Abstract

The utility model relates to a circuit system protection device, in particular relates to a surge protector. The surge protector comprises a lightning-preventive module, a lightning-preventive base, as well as a fusing module, wherein the lightning-preventive module is fixedly arranged on the lightning-preventive base, and the fusing module is arranged in the lightning-preventive module or in the lightning-preventive base. According to the structure, a short circuit protection circuit is arranged in the lightning-preventive module or in the lightning-preventive base as the fusing module, so that the residual voltage is almost zero, therefore, equipment can be more effectively protected, the surge protector is convenient to install and is space-saving, the installation cost of a power distribution cabinet can be saved, and an inductor and a communication module are combined to realize remote monitoring on the electricity leakage condition and realize the additional functions of monitoring fire disasters and the like.

Description

Surge Protector

Technical field

The utility model relates to a kind of protective device of Circuits System, especially a kind of Surge Protector.

Background technology

Surge protector (Surge protection Device) is indispensable a kind of device in the electronic equipment lightning protection, and the past often is called, Surge Protector.The effect that " lightning arrester " or " overvoltage protection device " English is abbreviated as the SPD. Surge Protector is that the instantaneous overvoltage of scurrying into power line, signal transmssion line is limited in the voltage range that equipment or system can bear; or powerful lightning current let out the inflow place, protect protected equipment or system not to be hit and damage.The type of Surge Protector is different by different purposes with structure, but it should comprise a non-linear voltage limiting element at least.The basic components and parts that are used for Surge Protector have: discharging gap, gas-discharge tube, piezo-resistance, inhibition diode and choking-winding etc.

But the function ratio of Surge Protector is more single at present; more and more can not satisfy the diversified demand of existing market; must add a fuse protection such as original Surge Protector; but install fuse separately additional; all there is inductance on fuse itself and the connection lead so, certainly exists very big residual voltage like this.

Summary of the invention

The purpose of this utility model is, the Surge Protector that a kind of function is many, applicability is wide is provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of Surge Protector; comprise lightning-protection module, lightning protection base; lightning-protection module is fixed on the lightning protection base, also comprises the fusing module, the fusing module be arranged in the lightning-protection module or the lightning protection base in.

Of the present utility modelly further be set to: comprise that also communication module, communication module are arranged in the lightning protection base.

Of the present utility modelly further be set to: insert in the loop of lightning protection base by an inductance at communication module.

Of the present utility modelly further be set to: described fusing module is a short-circuit protection circuit.

Said structure is provided with short-circuit protection circuit as the fusing module in lightning-protection module or in the lightning protection base; residual voltage is almost nil so; therefore can more effectively protect equipment; easy for installation; save the space, saved the installation cost of power distribution cabinet, and the combination by inductance and communication module; just can realize remote monitoring electric leakage situation, realize additional functions such as fire hazard monitoring.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of present embodiment;

Fig. 2 is the principle sketch of present embodiment.

Embodiment

With reference to figure 1; Fig. 2 as can be known; a kind of Surge Protector; comprise lightning-protection module 1; lightning protection base 2; lightning-protection module 1 is fastened on the U type lightning protection base 2; a short-circuit protection circuit is set in lightning protection base 2, and (it is that prior art is not done sign in the drawings that short circuit is hit in short circuit cruelly; do not influence those skilled in the art and implement this programme) as the fusing module; in lightning protection base 2, also be provided with a communication module; usually communication module is a communication chip; such as 485 communication chips; in the loop in the inductance access lightning protection base 2, just can realize signal and communication, just can realize the purpose of remote monitoring; safer when in use; because the existence of this communication module, if with long-range fire monitoring system, just can realize fire hazard monitoring.

Fusing module in the utility model can be arranged in the lightning-protection module, also can be provided with in the lightning protection base, but be arranged in the lightning-protection module, the structure more complicated, because the restriction of various factors, be arranged in the lightning protection base, more reasonable, so the utility model module that will fuse is arranged in the lightning protection base.

Obviously, the foregoing description only be for explanation clearly done for example, and be not qualification to execution mode.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And conspicuous variation of being extended out thus or change still are in the protection range of the present utility model.

Claims

1. a Surge Protector comprises lightning-protection module, lightning protection base, and lightning-protection module is fixed on the lightning protection base, it is characterized in that: also comprise the fusing module, the fusing module be arranged in the lightning-protection module or the lightning protection base in.
