Abstract
An integrated multiple stages serially connected lightning arrester for AC or DC power supply is composed of I/O terminals, automatic switch, the first protector consisting of zinc oxide modules and inductors, the second protector consisting of zinc oxide modules and inductors, the third protector consisting of two suppressing diodes, "Normal" and "Failure" indicating lamp, and additional elements. All said devices and elements are assembled on an insulating board in an iron box.
Description
The invention belongs to AC and DC power supply anti-induction thunder lightning arrester.
At present, various electronic informations, in the various electronic equipments as communication and navigation station, computer center, radio station etc., the lightning arrester of use is a very excellent nonlinear characteristic of utilizing zinc oxide (ZnO) piezo-resistance, promptly during normal voltage, piezo-resistance is equivalent to an insulator (resistance infinity), only pass through several microamperes of electric currents, and when the thunder and lightning high voltage hit, its resistance reduced sharply, a suitable good conductor releases lightning current shunting to greatly.Though such lightning arrester has been installed on the power supply of equipment, but still equipment has repeatedly been occurred and broken, also occur lightning arrester sometimes and do not broken, and the electronic equipment of its protection is broken.In order to improve fail safe, high price is not stinted by the unit that has, from buying a large amount of lightning arresters abroad, after loading onto, still unavoidably by the bad puzzlement of thunderbolt.Trace it to its cause, the lightning wave size is at random, happens suddenly, the energy size is difficult to expect that when the discharge capacity of lightning wave energy greater than lightning-arrest device, lightning arrester just may be broken, the energy of being released by lightning-arrest device does not directly enter electronic equipment, and equipment is broken.The voltage of protected electronic equipment tolerance is far below the residual voltage of lightning arrester; protected equipment normal voltage has only tens to several hectovolts, and the residual voltage of 220 volts of power supply zinc oxide arrester spares can reach 1.3KV, directly is added on the electronic equipment; therefore, also often equipment is broken.Zinc oxide arrester spare in the market, its response time lagged behind by the response time of the electronic equipment of its protection, and when thunderbolt took place, lightning arrester was not bad, and the electronic equipment of its protection has been broken earlier.
The objective of the invention is to for overcoming above-mentioned deficiency, and the lightning arrester of a kind of multistage integrated series in power circuit is provided.This type has adopted CPOWER PROTEC
Proprietary multistage integrated-IMP
Lightning surge resist technology (integrated multi-stage protection) has fundamentally solved the power (energy) of protective device and the problem of response speed.Thunder and lightning or other surges be through decay shunting step by step, pressure limiting, choked flow, make the surge overvoltage with semi-conductive response speed by clamped within the predetermined safe scope.Simultaneously, the electromagnetic time constant T of inductance component
L=8.9 (ms), it can avoid electronic equipment to be struck by lightning earlier fully.
The accompanying drawing drawing is described as follows:
