Abstract
The invention relates to a novel surge protector which mainly comprises a base (1) and a lightning protection module (2), wherein the lightning protection module (2) is internally provided with a relay (3), the relay (3) is connected with a surge suppressor (4) in series, and the relay (3) and the surge suppressor (4) are integrated into a whole by an electrical connection part (5); and when the surge suppressor (4) is short-circuited, the relay (3) can be disconnected so as to disengage the short-circuited surge suppressor (4) from a circuit. By reducing the length and the inductive reactance of a connection circuit, the invention improves the overall protection performance. The novel surge protector can be used for protecting various circuits for power, signals, control and other purposes.
Description
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 make 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 lightning-protection module (2), relay (3) is connected with surge suppression device (4), both connect by electrical fitting (5), relay (3) disconnects when surge suppression device (4) short circuit, and the surge suppression device (4) 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 lightning-protection module (2).Relay (3) is connected in series with surge suppression device (4) by the electrical fitting (5) of lightning-protection module (2).Lightning-protection module (2) is provided with relay replacement port (7).Can there be relay replacement port (7) on the lightning-protection module (2) yet.Breaking device (3) is made up of contact switch (9), control unit (10).
The invention has the advantages that: relay (3) is built in 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.
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 lightning-protection module (2).
Fig. 2 is an embodiment of relay (3).
Among the figure: 1, base, 2, lightning-protection module, 3, relay, 4, surge suppression device, 5, electrical fitting, 6, fixed mechanism, 7, the relay replacement port, 8, indicator light, 9, contact switch, 10, control unit, 11, housing, 12, 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 lightning-protection module (2), by fixed mechanism (6) relay (3) is connected and fixed, fixed mechanism (6) is a fixture independently in the present embodiment, is installed in the lightning-protection module (2).Relay (3) is connected with surge suppression device (4) connected in electrical series by the electrical fitting (5) in the lightning-protection module (2).Lightning-protection module (2) is installed on the base (1).Lightning-protection module (2) is provided with relay replacement port (7) and indicator light (8).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 (9), control unit (10), and be loaded in the same housing (11), housing (11) is provided with splicing ear (12), and relay (3) is connected to electrical fitting (5) in the lightning-protection module (2) by splicing ear (12).Control unit (10) has control terminal, is connected to control appliance, can receive control signal.When having short circuit current to occur, control unit (10) receives control signal, and by and contact switch (9) between the break-make of connector control contact switch (9), realize Surge Protector disengaging in the line.
Relay of the present invention (3) can be built in any position of lightning-protection module (2); what illustrate in the present embodiment is that relay (3) is parallel to base (1) form that lightning-protection module (2) installs of packing into, and all possible position relation is all in protection scope of the present invention.
