Description

Single-phase power supply low-pass lightning arrester
Technical field
The present invention relates to a kind of single-phase power supply low-pass lightning arrester.
Background technology
The existing power supply lightning protection device mostly is between live wire, ground wire Surge Protector to be set.In case thunderbolt, the high voltage that live wire, zero line are sensed discharges to equipment by power line, is easy to damage equipment, and particularly the Switching Power Supply in the modern comfort lies prostrate high pressure more and will damage, so between live wire, zero line Surge Protector must be set 1,000.
The existing power supply Surge Protector mostly adopts piezo-resistance, and it is the protector of votage limit type, and any switching mode (comprise gas put pipe, thyristor) Surge Protector is inapplicable because of the instantaneous interruption power supply.Piezo-resistance is by the zinc oxide ceramics sheet, and the parchment covering on the positive and negative is formed.It by chance constitutes one several thousand electric capacity that PF is big.After discharge finishes, have higher residual voltage (about more than 1,000 volts) toward contact on the piezo-resistance, high like this residual voltage is easy to power consumption equipment is caused damage; And the existing power supply lightning protection device can only be by discharging with the mode of earth short or mode by line disconnection completely cuts off thunder and lightning, and when thunder and lightning was attacked, power consumption equipment can't normal power supply.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defective that how to overcome the existing power supply lightning protection device, provide a kind of simple in structure, easy to use, thunder and lightning can discharge charge inducing before attacking in advance, do not interrupt normal power supply when thunder and lightning is attacked, and can completely cut off thunder and lightning, but the thunder and lightning single-phase power supply low-pass lightning arrester of residual voltage in the safe release piezo-resistance later.
For solving the problems of the technologies described above, this single-phase power supply low-pass lightning arrester comprises the Surge Protector SPD that is arranged between live wire, the ground wire 1And be arranged on Surge Protector SPD between zero line, the ground wire 2, it is characterized in that:
1., live wire is in series with inductance L successively from input to output 1, L 3, L 5, zero line is in series with inductance L successively from input to output 2, L 4, L 6This inductance is to form on the ferrite bead of high permeability with enough thick enamelled wire.It constitutes path to the impedance approximate zero of power supply.
2., inductance L 1And L 2, inductance L 5And L 6The common mode inductance (the common mode inductance i.e. coil of two inductance is wrapped on the same magnet ring, and the number of turn is identical, around to opposite) that partners respectively is connected with Surge Protector SPD between the input of live wire and the input of zero line 3In inductance L 1, L 3Between live wire and inductance L 2, L 4Between zero line between be connected with Surge Protector SPD 4
3., in inductance L 3, L 5Between live wire and inductance L 4, L 6Between zero line between be connected with capacitor C 1Inductance L 5Near live wire output one side and inductance L 6Be connected with capacitor C near between zero line output one side 2
4., the output of the output of live wire, zero line passes through capacitor C respectively 3, C 4Join with ground wire.
So design, Surge Protector SPD 3And inductance L 1, L 2Form first order filtering voltage-limiting protection; Surge Protector SPD 4And inductance L 3, L 4Form second level filtering voltage-limiting protection; Capacitor C 1And inductance L 5, L 6Form third level filtering discharge prevention; Capacitor C 2, C 3And C 4Constitute fourth stage discharge prevention.
Before thunder and lightning is attacked, the present invention can discharge the charge inducing that is subjected to thundercloud to influence generation between live wire and the zero line in advance, is that a process is arranged because thunder and lightning forms, and this lightning protection device has played and subtracted thunder lightning protection effect in this process, so very low to the earth mat requirement, general earth resistance gets final product less than 5 ohm.When thunder and lightning is attacked, after pressure limiting discharge of the present invention, scurry into the hurried decay of lightning current in the electric wire, and normal power supply can not interrupt; After the thunder and lightning, because the main concentration of energy of lightning wave is in the 5HZ frequency range, the present invention has the decay of 10db in this frequency range, in time discharges residual voltage in the piezo-resistance by ground wire, guarantees device security.
As optimization, described Surge Protector SPD 1, SPD 2, SPD 3, SPD 4Be piezo-resistance, SPD 3Starting resistor be higher than SPD 4Starting resistor; Inductance L 1=L 2=0.6～0.8mH, inductance L 5=L 6=0.5～0.9mH, inductance L 3=L 4=0.01～0.03mH.So design, better effects if.
That single-phase power supply low-pass lightning arrester of the present invention has is simple in structure, easy to use, thunder and lightning can discharge charge inducing before attacking in advance, do not interrupt normal power supply when thunder and lightning is attacked; but the advantage of residual voltage in the safe release piezo-resistance after the thunder and lightning; be the desirable lightning protection device of single phase poaer supply, be particularly useful for the protection of various network device.
