优选实施例的详细说明图1说明了控制系统10的一个优选实施例,其适合于波音757飞机,而图5说明了控制系统10的一个优选实施例,其适合于波音747飞机,每个方案都根据本发明设计,以便在电流不稳定被感测到的时候断开负载的电力。 Detailed description of the preferred embodiment of Figure 1 illustrates a preferred embodiment of the control system 10, which is adapted to the Boeing 757 aircraft, while Figure 5 illustrates a preferred embodiment of the control system 10, which is adapted to the 747, each program According to the present invention are designed to disconnect the load power in the current instability is sensed time. 参考图1和图5,本发明的可适用飞机的接地故障电路断流器10断开一个有线路侧24和一个有一个接地故障的负载侧26的电路20。 Referring to Figure 1 and Figure 5, the present invention is applicable to aircraft ground fault circuit interrupter 10 disconnect a load side 24 and a ground fault of a line side 26 of the circuit 20. 该负载可能是一个发动机,或牵引负载的任何电气装置,其中,设备或人员的保护措施被期望。 The load may be an engine, or any electrical device pulling loads, protection measures which are expected to equipment or personnel. 本发明的接地故障电路断流器包括一个电源30,一个传感器40,一个逻辑控制器50,和一个功率调节器60。 Ground fault circuit interrupter of the invention includes a power supply 30, a sensor 40, a logic controller 50, and a power regulator 60. 电源被配置来提供到逻辑控制器的电力,并且传感器被配置来感测电路20的线路侧24中的电流不稳定,以及输出一个传感器信号到逻辑控制器。 Power supply is configured to provide power to the logic controller, and the sensor is configured to sense the line 20 side current sensing circuit 24 is unstable, and outputs a sensor signal to the logic controller. 逻辑控制器被配置来接收和处理来自传感器的传感器信号,并且功率调节器被配置来接收来自逻辑控制器的输入以及在电流不稳定被感测到的时候切断到电路的负载侧的电力。 Logic controller is configured to receive and process the sensor signals from the sensors, and the power regulator is configured to receive input from the logic controller and the current instability is sensed when the load side of the circuit to cut off power.

图2和图6说明了电源的一个优选实施例的一个详图,并且图3和图7说明了逻辑控制器的一个优选实施例的一个详图。 Figure 2 and Figure 6 illustrates a power supply of a preferred embodiment of a detail, and FIG. 3 and FIG. 7 illustrates a detail of a preferred embodiment of logic controller of embodiment. 参考图4和图8,在本发明的一个优选实施例中说明了在本发明的控制系统中使用的一个传感器,本传感器优选地包括集成电路U7,它是一个当工作在10V的时候有一个233mV/A输出端的Amploc Pro 5霍耳效应线性传感器。 Referring to Figure 4 and Figure 8, in a preferred embodiment of the present invention shows a sensor in the control system of the present invention in use, the sensors preferably comprises an integrated circuit U7, which is a time when operating in a 10V 233mV / Amploc Pro 5 Hall effect linear sensor A output. 所有三个泵电力相线都经过传感器核心。 All three have been pumping power phase sensor core. kirchhcoff的电流定律指出,在一个节点中的净电流为零。 Current law kirchhcoff noted in a node of the net current is zero. 考虑到泵绕组的星形连接点并且回顾相绕组的输入,在用代数式求和的时候,相绕组中的净电流为零。 Taking into account the point of star connection winding and recalled pump input phase winding, with the algebraic sum of the time, the net current in the phase winding is zero. 如果存在一个接地故障,即其中电流通过传感器提供而不通过传感器返回,那么相线中的电流代数和将等于接地故障电流。 If there is a ground fault, i.e. wherein the current provided by the sensor does not return through the sensor, then the phase current will be equal to the algebraic sum of ground fault currents. 例如,一个中性线(fourth wire)可以被增加给星形连接点,并且被回到电源,而不经过传感器。 For example, a neutral line (fourth wire) may be added to the star connection point, and is returned to the power supply without passing through the sensor. 在所有四个线路中的净电流仍然为零,而经由三相线路被传递通过传感器的不稳定电流将等于在中性线中的电流。 Net current in all four lines remains zero, is transmitted via the three-phase line current by instability in the sensor will be equal to the current in the neutral line.

在一个优选实施例中,因为没有被测量到的不稳定,传感器的输出近似于电源电压的二分之一。 In one preferred embodiment, as instability is not measured, the output of the sensor approximately half the supply voltage. 放大器U3A把信号放大十倍。 The signal is amplified tenfold amplifier U3A. 增益通过电阻R5和R3的比值而被设置。 Gain by the ratio of resistors R5 and R3 are disposed. 在3db点处电容C4的电抗等于R5的电阻。 Electric 3db point of capacitor C4 is equal to the resistor R5 in the anti. 这出现于3386Hz。 This appears to 3386Hz. 电阻R1,R2,和R4偏置该放大器并且已经被选择,因此对电阻R4,要求其最大值为1兆欧,以在传感器被指定的更坏的高输出情况下,调整放大器输出到中间供给(mid supply)。 Resistors R1, R2, and R4 bias the amplifier and have been selected, so the resistors R4, require a maximum value of 1 megohm, to at worse case high output sensors are specified to adjust the amplifier output to mid supply (mid supply). 传感器的更坏的低输出情况的校准容易实现。 Worse case low output calibration sensor easily achieved.

放大器U3B和U3C,和电阻R6,R7,以及R8被设置来探测一个大于大约1.5A的电流不稳定。 Amplifiers U3B and U3C, and resistors R6, R7, and R8 are set to detect a current greater than approximately 1.5A is unstable. 来自放大器U3B或U3C的一个高输出指示一个不稳定存在于1.5A阈值的超额。 A high output from the amplifier or U3C U3B indication of instability exists in excess of a threshold value of 1.5A. 集成电路U4A对放大器U3B和U3C的输出起″或门″作用。 U4A IC amplifier output from U3B and U3C "or door" effect. 在它的输出端的一个逻辑0指示一个或别的故障条件存在。 A logic 0 at its output indicates one or the other side of the fault condition exists. 同时发生的不稳定输入可以被处理,但是因为一个正不稳定不能和一个负不稳定同时存在,所以物理上是不可能的。 Simultaneous input may be processed unstable, but not unstable due to a positive and a negative instability exist, it is physically impossible.

如果一个故障条件存在,那么它经过集成电路U5A给出一个逻辑1到包括集成电路U4B和U4C的锁存器(latch)。 If a fault condition exists, then it is given through a logic IC U5A to include an integrated circuit U4B and U4C latch (latch). 在管脚5的一个逻辑1强迫输出端管脚4为低(单位),关掉晶体管Q1,这去掉了到电力控制平台的驱动信号。 In a logic output pin 5 of a terminal pin 4 is forced low (unit), turn off the transistor Q1, which removes power to the drive signal control platform. 另一个到锁存器的输入端的管脚9一般是在逻辑0。 Another input of the latch pin 9 is generally in the logic 0. 这将引起管脚10到高(电位),通过给出一个逻辑1到管脚6而设置锁存器。 This will cause the pin 10 to a high (potential), by giving a logic 1 to pin 6 disposed latches.

在一个优选实施例中,上电序列把电力控制部分初始化到不工作模式。 In a preferred embodiment, the power-up sequence initializes the power control section to the non-operating mode. 这通过给出一个逻辑0到集成电路U5A的管脚2以模仿一个电流的不稳定情况来被完成。 This IC U5A 0 to pin 2 to mimic a current unstable situation to be done by giving a logic.

集成电路U5B,电阻R13,电容C5和二极管CR8产生的上电复位脉冲一般是7msec。 IC U5B, power-on reset pulse resistor R13, capacitor C5 and diode CR8 produce generally 7msec. 该复位由电容C5通过电阻R13充电到由IC U5B设置的阈值所用的时间决定。 The reset by the capacitor C5 is charged through resistor R13 to the threshold set by IC U5B elapsed time decision. 二极管CR8提供一个快速复位。 Diode CR8 provides a quick reset.

二极管CR1,CR2,CR3,CR4,CR5,和CR6形成一个全波三相电桥。 Diode CR1, CR2, CR3, CR4, CR5, and CR6 forming a three-phase full-wave bridge. 电容C1用作由电桥产生的281V峰值电压的存储装置。 Capacitor C1 is used as a storage device 281V peak voltage produced by the bridge. 优选地,调节器是一个有着非常规架构(abnormal architecture),在低端有感应器的补偿型(buck-type)配置。 Preferably, the regulator has a conventional architecture (abnormal architecture), there is at the low end of the sensor compensation type (buck-type) configuration. 因为电路不必涉及接地,所以这是可接受的。 Because the circuit does not have to involve the ground, so it is acceptable. 其实,板载的地线大约超出接地270V。 In fact, onboard ground by about grounding 270V.

优选地,转换开关在一个非常规模式中起作用。 Preferably, the switch is in a very scale formulas work. 如果它感测到输出电压是低电位,那么它打开并且一直保持到通过感应器L1的电流到达一个预确定值。 If it senses that output voltage is low, then it is opened and maintained until the current through inductor L1 reaches a pre-determined value. 否则,该循环被跳过。 Otherwise, the cycle is skipped. 电能被存储在感应器L1中并且通过二极管CR7被传输到输出电容器C3。 Energy is stored in inductor L1 and the capacitor C3 is transferred to the output through a diode CR7. 恰当的调整由齐纳管VR1和光耦合器U2确定。 U2 is determined by the appropriate adjustments Zener VR1 and optocouplers. 电容C2用来存储少量调节器用来运转它的内部电路的电能。 Capacitor C2 is used to store a small amount of operation of the regulator to power its internal circuitry.

参考图9到13,说明了本发明一个控制系统的一个可替换优选实施例,其适合于一个AC-DC应用,该操作在电流不稳定被感测到的时候切断电路。 With reference to Figure 9-13, illustrate the present invention, a control system according to an alternative preferred embodiment, which is suitable for an AC-DC application, the operation at unstable current is sensed when the cut-off circuit. 如图9所示,本发明的可适用飞机的接地故障电路断流器10断开一个有线路侧24和一个有一个接地故障的负载侧26的电路20。 As shown in Figure 9, the present invention is applicable to aircraft ground fault circuit interrupter 10 disconnect a load side 24 and a ground fault of a line side 26 of the circuit 20. 该负载可能是一个发动机,或牵引负载的任何电气装置,其中,设备或人员的保护措施是必须的。 The load may be a motor, or any electrical device tractive load, wherein the protection of equipment or personnel is necessary. 本发明的接地故障电路断流器包括一个电源30,一个传感器40,一个逻辑控制器50,和一个功率控制器60。 Ground fault circuit interrupter of the invention includes a power supply 30, a sensor 40, a logic controller 50, and a power controller 60. 电源被配置来提供到逻辑控制器的电力,并且传感器被配置来感测电路20的线路侧24中的电流不稳定,以及输出一个传感器信号到逻辑控制器。 Power supply is configured to provide power to the logic controller, and the sensor is configured to sense the line 20 side current sensing circuit 24 is unstable, and outputs a sensor signal to the logic controller. 逻辑控制器被配置来接收和处理来自传感器的传感器信号输入,并且功率控制器被配置来接收来自逻辑控制器的输入以及在电流不稳定被感测到的时候切断到电路的负载侧的电力。 Logic controller is configured to receive and process the sensor signal input from the sensor, and the power controller is configured to receive input from the logic controller and the current instability is sensed when the load side of the circuit to cut off power.

Kirchhcoff的电流定律指出在一个节点中的净电流为零。 Current law Kirchhcoff noted in a node of the net current is zero. 考虑到泵绕组的星形连接点并且回顾相绕组的输入,在代数求和时,相绕组中的净电流为零。 Taking into account the point of star connection winding and recalled pump input phase winding, when the algebraic sum of the net current in the phase winding is zero. 如果存在一个接地故障,即其中电流通过传感器提供而不通过传感器返回,那么相线中的电流代数和将等于接地故障电流。 If there is a ground fault, i.e. wherein the current provided by the sensor does not return through the sensor, then the phase current will be equal to the algebraic sum of ground fault currents. 例如,一个中性线可以被增加到星形连接点,并且被回到电源,而不经过传感器。 For example, a neutral point of star connection can be increased, and is returned to the power supply without passing through the sensor. 在所有四个线路中的净电流仍然为零,而经由三相线路被传输,通过传感器的不稳定电流将等于在中性线中的电流。 Net current in all four lines remained zero, and is transmitted via a three-phase line, the current through the sensor will be equal to the unstable current in the neutral line.

在一个优选实施例中,因为没有被测量到的不稳定,传感器的输出近似于电源电压的二分之一。 In one preferred embodiment, as instability is not measured, the output of the sensor approximately half the supply voltage. 放大器U3A把信号放大十倍。 The signal is amplified tenfold amplifier U3A. 增益通过电阻R5和R3的比值而被设定。 Gain by the ratio of resistors R5 and R3 is set. 在3db点处电容C4的电抗等于R5的电阻。 Electric 3db point of capacitor C4 is equal to the resistor R5 in the anti. 这出现在3386Hz处。 This occurs at 3386Hz. 电阻R1,R2,和R4偏置该放大器并且已经被选择,因此对电阻R4,要求其最大值为1兆欧,以在传感器被指定的更坏的高输出情况下,调整放大器输出到中间供给。 Resistors R1, R2, and R4 bias the amplifier and have been selected, so the resistors R4, require a maximum value of 1 megohm, to at worse case high output sensors are specified to adjust the amplifier output to mid supply . 传感器的更坏的低输出情况的校准容易实现。 Worse case low output calibration sensor easily achieved.

放大器U3B和U3C,和电阻R6,R7,以及R8被设置来探测一个大于大约1.5A的电流不稳定。 Amplifiers U3B and U3C, and resistors R6, R7, and R8 are set to detect a current greater than approximately 1.5A is unstable. 来自放大器U3B或U3C的一个高输出指示一个超过1.5A阈值的不稳定存在。 A high output from the amplifier or U3C U3B unstable than 1.5A indicating a threshold exists. 集成电路U4A对来自放大器U3B和U3C的输出进行″或″(处理)。 IC U4A output from amplifier U3B and U3C be "or" (processing). 在它的输出端的一个逻辑0指示总有一个故障条件存在。 At its output terminal a logic 0 indicates that there is always a fault condition exists. 同时发生的不稳定输入可以被处理,但是因为一个正不稳定不能与一个负不稳定同时存在,所以物理上是不可能的。 Simultaneous input may be processed unstable, but not unstable due to a positive and a negative of instability exist, it is physically impossible.

如果一个故障条件存在,那么它经过集成电路U5A给出一个逻辑1到包括集成电路U4B和U4C的锁存器。 If a fault condition exists, then it passes through IC U5A gives a logic 1 to the integrated circuit comprises a latch U4B and U4C. 在管脚5的一个逻辑1强迫输出端管脚4为低电位,关掉晶体管Q1,这去掉了到电力控制平台的驱动信号。 In a logic output pin 5 of a terminal pin 4 is forced to a low potential, to turn off the transistor Q1, which removes power to the drive signal control platform. 另一个到锁存器的输入端,管脚9一般是在逻辑0。 Another input of the latch, pin 9 is generally in the logic 0. 这将引起管脚10为高电位,通过给出一个逻辑1到管脚6而设置锁存器。 This will cause the pin 10 to a high level, by giving a logic 1 to pin 6 disposed latches.

在一个优选实施例中,上电序列把电力控制部分初始化到不工作模式。 In a preferred embodiment, the power-up sequence initializes the power control section to the non-operating mode. 这通过提供一个逻辑0到集成电路U5A的管脚2以模仿一个电流的不稳定情况而实现。 This 0 to pin 2 of IC U5A to mimic a current instability is achieved by providing a logic.

集成电路U5B,电阻R13,电容C5和二极管CR8产生的上电复位脉冲一般是7msec。 IC U5B, power-on reset pulse resistor R13, capacitor C5 and diode CR8 produce generally 7msec. 该复位由电容C5通过电阻R13充电到由集成电路U5B设置的阈值所花费的时间确定。 The reset by the capacitor C5 is charged to the time threshold set by IC U5B takes determined by resistor R13. 二极管CR8提供一个快速复位。 Diode CR8 provides a quick reset.

二极管CR1,CR2,CR3,CR4,CR5,和CR6形成一个全波三相电桥。 Diode CR1, CR2, CR3, CR4, CR5, and CR6 forming a three-phase full-wave bridge. 电容C1担当由电桥生产的281V峰值电压的存储装置。 Capacitor C1 play storage device produced by the bridge 281V peak voltage. 该调节器是一个有非常规架构的,在低端有感应器的补偿型配置。 The regulator is an unconventional structure, there is at the low end of the compensated sensor configuration. 因为电路不必涉及接地,所以这是可接受的。 Because the circuit does not have to involve the ground, so it is acceptable. 实际上,因为分别为10V和20V的输入,板载地线大约超出接地270v和260V。 In fact, because of 10V and 20V respectively input, onboard ground by about grounding 270v and 260V.

优选地,转换开关在一个非常规模式中起作用。 Preferably, the switch is in a very scale formulas work. 如果它感测到一个输出电压低,那么相应的控制器打开并且一直保持到通过感应器L1或L1A的电流到达一个预先确定值。 If it senses an output voltage is low, the corresponding controller turns on and maintained until the inductor L1 or L1A reaches a current through the predetermined value. 否则,该循环被跳过。 Otherwise, the cycle is skipped. 电能被存储在感应器L1或L1A中并且通过二极管CR7或CR7A被传输到输出电容器C3或C3A。 Energy is stored in inductor L1 or L1A and transmitted to the output capacitor C3 or C3A through diode CR7 or CR7A. 恰当的调整由齐纳管VR1或VR1A和光耦合器(opto-coupler)U2或U2A确定。 U2 or U2A appropriate adjustments determined by Zener VR1 or VR1A and optocoupler (opto-coupler). 电容C2或C2A用来存储少量能量,每个相应的调节器用该能量来运转内部电路。 Capacitor C2 or C2A used to store a small amount of energy, each respective conditioner energy to operate the internal circuit.
