Abstract

The utility model relates to a novel surge protector, which comprises a base (1), a lightning protection module (2) and a short-circuit protection module (3), wherein the short-circuit protection module (3) is in plug-in connection or in compression joint to lightning protection module (2), and connected with the lightning protection module (2) in series, the short-circuit protection module (3) isswitched out when the lightning protection module (2) is short-circuited so as to enable the short-circuited lightning protection module (2) to be separated from a circuit, since the length and the inductive reactance of a connecting circuit is reduced, the whole protection performance is improved, and the novel surge protector can be applicable to the protection of various circuits such as a power circuit, a signal circuit, a control circuit and the like.

Description

A kind of novel surge protective device

Technical field

The utility model relates to a kind of novel surge protective device, belongs to the surge guard technology field of electronic electric equipment.

Technical background

The line surge that a variety of causes such as thunder and lightning cause is to cause the major reason that electric/electronic device is aging or damage, and on metallic circuits such as the power line of electric/electronic device, holding wire, control line Surge Protector being installed is one of important safeguard procedures of being taked.In this technical field; the problem that exists is at present: Surge Protector is in protection equipment; himself device deterioration gradually damages or directly damages under excessive surge impact; the switching mode device then can produce afterflow; all have a strong impact on the operate as normal of equipment or system; especially it is even more serious that device failure causes the situation of short circuit, and should in time break away from circuit with it this moment, otherwise phenomenons such as burning, switch trip, power failure, signal transmission fault will occur.

Addressing the above problem existing technical method at present, is in that connect on the circuit of Surge Protector independently a circuit breaker or a fuse are installed, as the short-circuit protection of Surge Protector.This method exists following problem: series connection circuit breaker or fuse on the Surge Protector circuit, and it is big to take up room, the various coiling of connection line; circuit induction reactance strengthens; and making its response time slack-off, circuit two ends residual voltage raises, and causes whole surge protection effect to descend.

The utility model content

In order effectively to overcome the above problems, the utility model proposes a kind of novel surge protective device.

The purpose of this utility model provides a kind of novel surge protective device, short-circuit protection module (3) is pegged graft or is crimped on the lightning-protection module (2), short-circuit protection module (3) is connected with lightning-protection module (2), short-circuit protection module (3) disconnects when lightning-protection module (2) short circuit, and the lightning-protection module (2) that is short-circuited is spun off from circuit; Owing to reduced connection line length and induction reactance, therefore improved the integral protection performance; Can be applied to the protection of various circuits such as power supply, signal, control.

The utility model is realized by the following technical solutions: novel surge protective device comprises base (1), lightning-protection module (2), short-circuit protection module (3), and short-circuit protection module (3) is pegged graft or is crimped on the lightning-protection module (2).Be connected for connected in electrical series between lightning-protection module (2) and the short-circuit protection module (3).Short-circuit protection module (3) comprises short-circuit protection device (8), shell (7), electrical fitting (9).Described short-circuit protection module (3) is fuse or circuit breaker or relay.

Advantage of the present utility model is: short-circuit protection module (3) is pegged graft or is crimped on the lightning-protection module (2), Surge Protector need not to select for use short-circuit protection again, reduced to install the shared space of Surge Protector, and do not need lead to connect, can reduce the lead inductance amount, accelerate response speed, reduced residual voltage; Therefore, in time it is broken away from the existing problem of prior art method that circuit connects when efficiently solving above-mentioned Surge Protector fault.
