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, 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 utility model is realized 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).

Advantage of the present utility model is: relay (3) is built in the base (1), 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.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an embodiment of the present utility model, 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:

An embodiment of the present utility model 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 described in the utility model (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 range of the present utility model.
