Abstract
The invention relates to an isolation switch device which comprises a device housing and is characterized in that the device housing is internally provided with a base, and a stationary contact bridge is arranged on the base and sleeved with an encloser. In addition, a socket is arranged at the bottom of the encloser, and a cover plate is arranged at the top end of the encloser. Furthermore, a contact support component is arranged on one side of the cover plate, and an interlocking piece is arranged on the other side of the cover plate. In this case, the encloser and the contact support component form an isolation module; a major loop of the isolation module is closed; then a subsidiary loop is closed; a body power supply is turned on; an electromagnet coil is powered on; a body major loop is closed; and the switch works normally. The subsidiary loop is opened to ensure that the body power supply is off and an electromagnet is powered off, the main body major loop is opened, then the major loop of the isolation module is opened, so that the safety is realized, and the operation is very convenient.
Description
Technical field
The present invention relates to a kind of switching device, relate in particular to a kind of isolation switch device.
Background technology
Control well combines together with the function of protection switch electrical equipment (CPS) with circuit breaker, contactor, thermal relay; reasonable coordination the work that cooperates of each apportion appliance component protective feature, control characteristic; can replace conventional motors control and use, also can be widely used in occasions such as automation centralized control system and Fieldbus Based dcs.
Isolating switch is a kind of switchgear that does not have arc-control device, is mainly used to disconnect the circuit of zero load electric current, and insulating power supply has tangible cut-off point when gate-dividing state, to guarantee the safety inspection of other electric equipments.When "on" position, can pass through normal duty electric current and short-circuit current reliably.Because it does not have special arc-control device, can not cut off load current and short circuit current.Therefore, isolating switch can only be operated under the situation that circuit has been disconnected by circuit breaker, forbids on-load to be operated, in order to avoid cause serious equipment and personal injury.
There is the inconvenience of risk and the operability of fail safe in traditional isolation module.Must disconnect the body major loop earlier, as not disconnecting, directly unplug isolation module, can cause electric arc burn.Very strict to operational norm and sequence requirement, careless slightly meeting leads to serious consequence.
Summary of the invention
Purpose of the present invention is exactly in order to solve the above-mentioned problems in the prior art, and a kind of isolation switch device is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of isolation switch device, include crust of the device, wherein: be provided with base in the described crust of the device, described base is provided with the stationary contact bridge, be arranged with case on the described stationary contact bridge, described case bottom is provided with socket, and described case top is provided with cover plate, one side of described cover plate is provided with the contact supporting assembly, and the opposite side of described cover plate is provided with locking part.
Further, above-mentioned a kind of isolation switch device, wherein: described contact supporting assembly includes receiver, is provided with elastic parts in the described receiver, and described elastic parts top is provided with contact.
Further, above-mentioned a kind of isolation switch device, wherein: described elastic parts is spring.
Again further, above-mentioned a kind of isolation switch device, wherein: described case sidewall is provided with slotted eye.
The advantage of technical solution of the present invention is mainly reflected in: case and contact supporting assembly constitute isolation module, allow the major loop of isolation module connect earlier, auxiliary connection then, and the body power connection, electromagnet coil power, the body major loop closes, the switch operate as normal.Thus, adopt auxiliaryly to disconnect earlier, guarantee that the body power supply disconnects and electromagnet does not have electricity, and then after guaranteeing that the main body major loop disconnects, disconnect the major loop of isolation module again, reaching fail safe, and operation is quite convenient.
Description of drawings
Purpose of the present invention, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solution of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of protection of present invention.In the middle of these accompanying drawings,
Fig. 1 is the unitary construction schematic diagram of isolation switch device;
Fig. 2 is that contact flicks the auxiliary work schematic diagram that disconnects in back;
Fig. 3 is that case is mentioned the work schematic diagram that the back major loop disconnects;
Fig. 4 is the work schematic diagram that isolation switch device disconnects fully.
Embodiment
A kind of isolation switch device shown in Fig. 1～4 includes crust of the device 1, and its unusual part is: be provided with base 2 in the crust of the device 1 that the present invention adopts.Specifically, base 2 is provided with stationary contact bridge 3.And, be arranged with case 4 at stationary contact bridge 3.Simultaneously, case 4 bottoms are provided with socket 5, and case 4 tops are provided with cover plate 6.As shown in Figure 1, a side of cover plate 6 is provided with contact 9 supporting assemblies, and the opposite side of cover plate 6 is provided with locking part 7.
With regard to the present invention's one preferred implementation, consider and to realize the effect that postpones to link that contact 9 supporting assemblies that the present invention adopts include receiver 8.Specifically, be provided with elastic parts in this receiver 8, and the elastic parts top is provided with contact 9.Moreover, consider upspringing smoothly of contact 9, elastic parts is spring 10.
In conjunction with actual operating position of the present invention: comprise and resolve open procedure and the process of closing.
The disconnection process: as shown in Figure 2, slip off locking part 7 to the right, mentioning has slight feel when cover plate 6(has just pulled up), at first the contact 9 of Fu Zhu contact 9 supporting assemblies is upspring earlier, realizes auxiliary the disconnection.Simultaneously, be accompanied by auxiliary the disconnection, this moment, the body power supply also disconnected thereupon, and electromagnet coil will not have electricity yet, and then guarantee that body cuts off the power supply.
Then, as shown in Figure 3, continue to mention cover plate 6, when the stroke of cover plate 6 and case 4 reached terminal point, socket 5 was along with case 4 upwards is raised together, and the major loop of isolation module disconnects then.And the cover plate 6 of mentioning can be inserted into case 4, and case 4 sidewall grooved holes are specialized in the position that locking part 7 inserts, and so far whole disconnection process is finished, and the position relation of each parts as shown in Figure 4.
The process of closing: remove locking part 7 to the right, press lower cover 6, socket 5 and stationary contact bridge 3 contact earlier in this process.Afterwards, continue to press lower cover 6, with auxiliary contact 9 supporting assemblies by on earth.Then, be moved to the left locking part 7, block case 4, it can not be mentioned.
Realize auxiliary function of closing this moment, the energising of body power supply, electromagnet coil power then, the body major loop closes, the switch operate as normal.
By above-mentioned character express as can be seen, behind employing the present invention, case and contact supporting assembly constitute isolation module, allow the major loop of isolation module connect earlier, auxiliary connection then, body power connection, electromagnet coil power, the body major loop closes, the switch operate as normal.Thus, adopt auxiliaryly to disconnect earlier, guarantee that the body power supply disconnects and electromagnet does not have electricity, and then after guaranteeing that the main body major loop disconnects, disconnect the major loop of isolation module again, reaching fail safe, and operation is quite convenient.
