Power supply;It is characterized in that:The live wire input connects fire wire output end, the zero line input connection zero line output end;Institute
State the first piezo-resistance and the second piezo-resistance for being connected with and being serially connected between live wire input and zero line input;Described
Gas-discharge tube is connected between the connection end and ground wire input of one piezo-resistance and the second piezo-resistance;The live wire input
The 3rd piezo-resistance is also associated between end and zero line input.
When supply line caused by being struck by lightning live wire input terminal voltage more than the first piezo-resistance threshold value when, the first pressure-sensitive electricity
The rapid conducting of resistance, live wire input is discharged over the ground by the first piezo-resistance and gas-discharge tube, by voltage clamping to threshold value model
In enclosing;Similarly, when supply line caused by being struck by lightning zero line input terminal voltage more than the second piezo-resistance threshold value when, second is pressure-sensitive

In the range of;Further to protect late-class circuit, in input the 3rd piezo-resistance also in parallel, when input voltage exceeds its threshold value
When, the 3rd piezo-resistance is turned on rapidly, and by voltage clamping to threshold range, the incubator box for domestic fowl circuit of rear class is carried out effectively
Lightning protection.
Further, first piezo-resistance, the second piezo-resistance, the 3rd piezo-resistance are 20D561K.20D561K
Piezo-resistance is cheap, working stability.
Further, the gas-discharge tube is B8G600L.B8G600L gas-discharge tubes are cheap, working stability.
The beneficial effects of the utility model are:It is gentle using the first piezo-resistance, the second piezo-resistance, the 3rd piezo-resistance
Body discharge tube, can be by the threshold of the rapid clamper of voltage to piezo-resistance when supply line, which is struck by lightning, causes input terminal voltage to raise
In the range of value, effective lightning protection can be carried out to the incubator box for domestic fowl circuit of rear class.
Brief description of the drawings
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
As shown in figure 1, embodiment of the present utility model, a kind of incubator box for domestic fowl lightning protection circuit, including input and
Output end;The input includes live wire input L1, zero line input N1 and ground wire input PE, the live wire input L1
Connect the live wire of civil power, the zero line of zero line input N1 connection civil powers, ground wire input PE ground connection;The output end includes live wire
Output end L2 and zero line output end N2, the output end is powered to incubator box for domestic fowl;It is characterized in that:The live wire input L1
Connect fire wire output end L2, the zero line input N1 connection zero line outputs end N2;Live wire input L1 and the zero line input
The the first piezo-resistance RV1 and the second piezo-resistance RV2 being serially connected are connected between the N1 of end;The first piezo-resistance RV1
And second piezo-resistance RV2 connection end and ground wire input PE between be connected with gas-discharge tube GDT;The live wire input
The 3rd piezo-resistance RV3 is also associated between L1 and zero line input N1.
When supply line is caused threshold value of the live wire input L1 voltages more than the first piezo-resistance RV1 by being struck by lightning, first
Piezo-resistance RV1 is turned on rapidly, and live wire input L1 is discharged over the ground by the first piezo-resistance RV1 and gas-discharge tube GDT, will
Voltage clamping is in threshold range;Similarly, being struck by lightning when supply line causes zero line input N1 voltages more than the second pressure-sensitive electricity
