As shown in fig. 1-3, a lightning arrester comprises a bakelite 1 fixed on the surface of a bracket 6 and a shunt 2, wherein a coil 3 is connected between the bakelite 1 and the shunt 2; the shunt 2 comprises a cavity groove 21 and a sealing cover 22 for sealing the cavity groove 21, and a first terminal 23 and a second terminal 24 for connecting with the outside are arranged along the two ends of the cavity groove 21; in the cavity slot 21, the first terminal 23 and the second terminal 24 are respectively connected with a graphite sheet module 25;
a first connecting sheet 4 is connected to the bakelite 1, a second connecting sheet 5 is connected to the first binding post 23, and the first connecting sheet 4 and the second connecting sheet 5 are connected through the coil 3;
when the wiring is installed, the first connecting sheet 4 is used for being connected with a power module, the second connecting sheet 5 is used for being connected with an electricity utilization module, and the second binding post 24 is used for being grounded. Specifically, the power module includes a power supply for supplying power to the power utilization module, and is not limited to a household power supply or a mobile power supply; the power utilization module is all equipment or devices which use electricity to work.
In an outdoor enclosure power supply embodiment, the power utilization module is an electric wire wound around the enclosure, and when the enclosure is struck by lightning, the enclosure generates a high-voltage current, and the current needs to be drained to the ground to protect the enclosure power supply. The wiring layout is as follows:
fixing a bracket 6 on a fence timber pile, connecting a power supply module with a first connecting sheet 4 through a cable, and connecting a second connecting sheet 5 with an electric wire on the fence through the cable; the second terminal 24 is connected to a steel plate by a cable, and the steel plate is inserted into the ground, and the steel plate in this embodiment may be made of other conductive metals.
The working principle is as follows: the coil 3 on the arrester allows current to flow from the power supply of the fence (power module) to the fence and generates a magnetic field around the coil 3, but when a lightning strikes the fence, a very high voltage is instantaneously generated, when the voltage tries to reverse the current, it generates an inertia-induced resistance on the coil 3, which hinders the flow of the current, and tries to reverse the magnetic field, forcing the high-voltage current to stay and look for other flow directions, and then the voltage can be shunted to the ground through the steel plate connected to the grounding pile, thereby achieving the purpose of protecting the power supply of the fence.
