Embodiment
Below in conjunction with accompanying drawing, content of the present utility model is elaborated with a kind of preferred embodiment.
Embodiment 1
The lightning protection power source line comprises attaching plug, the connector that is connected with electrical equipment, is provided with lightning arrester between described attaching plug and described connector, and described lightning arrester inside is provided with circuit board.
With reference to shown in Figure 1; be provided with live wire 1, zero line 2 and ground wire 3 on circuit board; be arranged in parallel first surge protecter 4 between live wire 1 and zero line 2; be arranged in parallel second surge protecter 5 between live wire 1 and ground wire 3, be arranged in parallel the 3rd surge protecter 6 between zero line 2 and ground wire 3.
With reference to shown in Figure 2; described surge protecter comprises housing 8, is positioned at the hollow bulb 9 of housing 8 inside, is embedded two terminals 11 on housing; described hollow bulb 9 has the path 10 that runs through housing; one end of two terminals 11 stretches into hollow bulb 9 and is oppositely arranged, and the other end extends outside housing 8 and is arranged on circuit board.
Be connected with overload protective device on live wire 1, and described overload protective device is arranged on the front of the first surge protecter 4, the second surge protecter 5 and the 3rd surge protecter 6.
In the present embodiment, overload protective device is fuse 7.
The first surge protecter arranges 4 fronts at the second surge protecter 5 and the 3rd surge protecter 6.
After the abnormally high-voltage of thunderbolt generation enters power line; first by the first surge protecter 4 discharges; carry out respectively discharge between live wire and ground wire, zero line and ground wire by the second surge protecter 5 and the 3rd surge protecter 6 subsequently, the electric current of discharge generation flows out by ground wire.
