Description
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

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
