Abstract

The invention relates to a novel surge protector. The surge protector mainly comprises a pedestal (1) and a lightning-proof module (2), wherein a relay (3) is arranged in the pedestal (1); the relay (3) is connected in series with the lightning-proof module (2) and the two are integrated into a whole through the pedestal (1); the relay (3) is cut off when the lightning-proof module (2) is short-circuited, so that the short-circuited lightning-proof module (2) is separated from the line; because the length and the inductive reactance of a connecting line are reduced, the integral protection performance is improved; and the surge protector can be applied to protection of various lines such as power line, signal line, control line and the like.

Description

A kind of novel surge protective device

Technical field

The present invention relates to a kind of novel surge protective device, belong 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.

Summary of the invention

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

The purpose of this invention is to provide a kind of novel surge protective device, relay (3) is built in the Surge Protector, relay (3) is connected with lightning-protection module (2), both are integrated in one by base (1), relay (3) disconnects when lightning-protection module (2) short circuit, and the lightning-protection module 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 present invention realizes by the following technical solutions: novel surge protective device mainly is made up of base (1) and lightning-protection module (2), built-in relay (3) in the base (1).Relay (3) is connected in series with lightning-protection module (2) by the electrical fitting (4) of base (1).Base (1) is provided with relay replacement port (6).Can there be relay replacement port (6) on the base (1) yet.Relay (3) is made up of contact switch (8), control unit (9).

The invention has the advantages that: relay (3) is built in the base (1), Surge Protector need not to select for use short-circuit protection again, has reduced the shared space of Surge Protector is installed, and has not needed 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.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is one embodiment of the present of invention, and relay (3) is built in the schematic diagram of base (1).

Fig. 2 is an embodiment of relay (3).

Among the figure: 1, base, 2, lightning-protection module, 3, relay, 4, electrical fitting, 5, fixed mechanism, 6, the relay replacement port, 7, indicator light, 8, contact switch, 9, control unit, 10, housing, 11, splicing ear.

Embodiment

The concrete scheme of embodiment is as follows:

One embodiment of the present of invention as shown in Figure 1, in the present embodiment, relay (3) is built in the base (1), by fixed mechanism (5) relay (3) is connected and fixed, fixed mechanism (5) is a fixture independently in the present embodiment, is installed in the base (1).Relay (3) is connected with lightning-protection module (2) connected in electrical series by the electrical fitting (4) in the base (1).Lightning-protection module (2) is installed on the base (1).Base (1) is provided with relay replacement port (6) and indicator light (7).Relay (3) is selected the device or the circuit that can bear very big surge impact and can move for use under the minute short circuit current conditions.

An embodiment of relay as shown in Figure 2 (3), in the present embodiment, relay (3) is made up of contact switch (8), control unit (9), and be loaded in the same housing (10), housing (10) is provided with splicing ear (11), and relay (3) is connected to electrical fitting (4) in the base (1) by splicing ear (11).Control unit (9) has control terminal, is connected to control appliance, can receive control signal.When having short circuit current to occur, control unit (9) receives control signal, and by and contact switch (8) between the break-make of connector control contact switch (8), realize Surge Protector disengaging in the line.

Relay of the present invention (3) can be built in any position of base (1), and what illustrate in the present embodiment is the form that relay (3) is installed perpendicular to base (1), and all possible position relation is all in protection scope of the present invention.
