The utility model embodiment provides a kind of lightning protection device of high voltage supply circuit, solves in prior art to electricity When power equipment takes lightning measure, the lightning-arrest impact of signal is not considered, so as to easily cause the failure of power supply signal.
In order to solve above-mentioned technical problem, the utility model embodiment provides a kind of lightning protection of high voltage supply circuit and fills Put, including power protecting circuit, holding wire protection circuit and earthed circuit, the holding wire protection circuit includes being sequentially connected Signal input part, induction coil, fuse, there is forward conduction and the reverse lightning protection circuit and signal output part of cut-off, The lightning protection circuit includes that at least one diode and lightning rod, the power protecting circuit include power source surge protector, institute State power protecting circuit and holding wire protection circuit is connected to earthed circuit.
Further, described lightning rod one end connects power protecting circuit, and the other end connects earthed circuit.
Further, the lightning rod is specially transient state power supply killer tube TVS or piezo-resistance.
The utility model embodiment at least has the following technical effect that or advantage:
Due to be provided with the lightning protection device of the high voltage supply circuit power protecting circuit, holding wire protection circuit and Earthing power supply, signal input part that the holding wire protection circuit includes being sequentially connected, induction coil, fuse, has positive guide The lightning protection circuit and signal output part of logical and reverse media, the lightning protection circuit include at least one diode and lightning rod, should Power protecting circuit includes that power source surge protector, power protecting circuit and holding wire protection circuit are all connected with earthed circuit, solution When lightning measure is taken to power equipment in prior art of having determined, do not consider the lightning-arrest impact of signal, so as to easily make Into the failure of power supply signal, and then the generation of such failure can be prevented effectively from.
Description of the drawings
Module diagrams of the Fig. 1 for the lightning protection device of the utility model embodiment mesohigh supply line.
Specific embodiment
, by providing a kind of lightning protection device of high voltage supply circuit, it is right in prior art to solve for the utility model embodiment When lightning measure taken by power equipment, the lightning-arrest impact of signal is not considered, so as to easily cause the failure of power supply signal.
In order to solve above-mentioned technical problem, below in conjunction with Figure of description and specific embodiment to above-mentioned technology Scheme is described in detail.
A kind of lightning protection device of high voltage supply circuit that the utility model is provided, as shown in figure 1, including power protecting circuit 10th, holding wire protection circuit 20 and earthed circuit 30, the holding wire protection circuit include the signal input part being sequentially connected 201st, induction coil 202, fuse 203, there is forward conduction and the reverse lightning protection circuit 204 and signal output part of cut-off 205, the lightning protection circuit includes at least one diode and lightning rod, and the power protecting circuit 10 includes power source surge protector 101, the power protecting circuit 10 and holding wire protection circuit 20 are connected to earthed circuit 30, wherein, holding wire protection electricity The signal output part 205 on road 20 connects the earthed circuit 30 such that it is able to which heavy current is introduced the earth, protects power equipment.
In a particular embodiment, the lightning rod one end connects power protection electric power 10, and the other end connects earthed circuit 30, the lightning rod is specially transient state power supply killer tube TVS or piezo-resistance.
When thunder and lightning occurs, heavy current effectively can be imported by the lightning protection device of the high voltage supply circuit by lightning protection circuit Greatly, and ensure that signal line and the power supply of power supply unit normally effectively work.
Although having been described for preferred embodiment of the present utility model, those skilled in the art once know substantially Creative concept, then can make other change and modification to these embodiments.So, claims are intended to be construed to wrap Include preferred embodiment and fall into the had altered of the utility model scope and change.
