Wherein, sticking department is nut.
When Top electrode is moved to correct position, locked by nut so that it is suitable in this that Top electrode is stablized
Position.
Wherein, Top electrode, the shape of bottom electrode are the high segment for being less than the radius of a ball, and two electrode cambered surfaces are corresponding.
Segment is the spherical smaller portions cut by plane, i.e. the height of segment is not more than the radius of a ball；Two electrode cambered surfaces are relative
Should, it is ensured that the uniformity of electric field between upper/lower electrode.
Wherein, Top electrode, the shape of bottom electrode are hemisphere, and two electrode cambered surfaces are corresponding.
Upper/lower electrode uses hemispheroidal design, and because sphere gap is uniform electric field, discharge voltage is stable, and dispersiveness is small,
Protective value is good.
Wherein, the cambered surface of Top electrode is less than the cambered surface of bottom electrode.
Increase bottom electrode cross-sectional area, further the dispersiveness of reduction electric field, improves protective value.
Wherein, in addition to counter and connecting plate, connecting plate is fixed on lower installation board, and counter is fixed on connecting plate
On；Counter is in electrical connection with arrester main body, for recording discharge time.
Because arrester installation site is higher, due to extraneous factor influence, such as wind so that counter can be swung at any time will
Counter is fixed together by connecting plate with lower installation board, undoubtedly adds the steadiness of counter so that data acquisition is more
For convenience；Using the design of counter, number of lightning strokes is able to record that, the thunderbolt frequency of this area is intuitively known, this data can
For the strick precaution of later stage thunder and lightning.
Wherein, counter is with the low-voltage end of arrester main body in electrical connection, and the shell of counter is connected with ground wire.
The electric current produced that is struck by lightning is depressured by the resistance in arrester main body, and arrester body top is high voltage end,
Arrester bottom part body is low-voltage end, and counter and the low-voltage end of arrester main body are in electrical connection, and electric current is by keeping away
The decompression of resistance, extends the service life of counter in thunder device main body.
Wherein, in addition to disconnector, disconnector one end is with counter in electrical connection, and the other end is low with arrester main body
Voltage end is in electrical connection.
The design of disconnector, when arrester main body breaks down, can be such that arrester main body lead is disconnected with electric power system,
Lasting power-off is prevented, the protectiveness between circuit is improved.
