Detailed Description
As shown in fig. 1, an insulating support for withstand voltage test of lightning arrester comprises an insulating support base 1 as shown in fig. 2, wherein the insulating support base is a black insulating rubber mat of 400mm 30mm, a groove 2 of 300mm 20mm is arranged inside the insulating support base, the insulating support base has an insulation grade of 35kV, and can bear the test voltage applied during withstand voltage test of most lightning arresters. The guide rail base 3 is arranged in the groove, the specification is 300mm 30mm, and the transverse length of the guide rail is 300mm at most, and the guide rail is arranged in the groove of the insulating rubber mat.
Two telescopic support rods 8, as shown in fig. 3, have a longitudinal maximum rod length of 700mm. The device comprises an outer rod 4, wherein the bottom of the outer rod 400mm long is connected with an 80mm and 35kV insulation-grade insulation rubber column 5, and the bottom of the outer rod is provided with a guide groove 6 matched with a guide rail; the length of the inner rod 7 is 300mm, the top end of the inner rod is a cambered surface with the radius of 10mm, and the semi-ring bodies 9 with the length and the width of 15mm are used for dragging two ends of the lightning arrester; the maximum width between the two supporting rods is 300mm, and the distance between the two supporting rods can be adjusted in a sliding mode according to the size of the lightning arrester. Wherein, the outer pole of a bracing piece has ground terminal, and ground terminal uses BV2.5mm, long 3000 mm's earth connection 11, sets up intelligent control circuit breaker 12 on the ground terminal. When the lightning arrester is in a withstand voltage test, the intelligent control circuit breaker is in an open circuit state, and the positive electrode of the lightning arrester is insulated from the ground; after the test voltage drops to 0, the intelligent control circuit breaker is closed through remote control, and at the moment, the positive electrode of the lightning arrester is grounded and discharges through the grounding wire.
