Load switch

Abstract

The invention relates to a load switch. The load switch comprises a front partition plate, a rear partition plate, an upper cross beam, a lower cross beam, a grounding static contact seat mounting plate and a rotating shaft; the upper cross beam and the lower cross beam are made of insulating plastic; the rear partition plate is fixedly connected with the front sides of the upper cross beam, the lower cross beam and the grounding static contact seat mounting plate through bolts; and the front partition plate is fixedly connected with the rear sides of the upper cross beam, the lower cross beam and the grounding static contact seat mounting plate through bolts. An upper metal support and a lower metal support in an existing load switch are omitted, so the overall weight of the load switch is reduced; the cross beams made of the insulating plastic are directly fixed between the front partition plate and the rear partition plate through the connecting bolts, so the whole load switch is more convenient and easier to disassemble and assemble, and good in insulating performance; and the insulating composite material is adopted, so the load switch is resistant to high temperature.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a load switch. Background technique [0002] The existing load switch includes a front partition, a rear partition, an upper bracket, a lower bracket, and a grounding static contact seat mounting plate. The upper bracket, the lower bracket, and the grounding static contact seat mounting plate are fixedly arranged on the front bulkhead and the grounding static contact seat by welding Between the rear bulkheads; then the upper beam and the lower beam are respectively installed on the upper bracket and the lower bracket, and the upper and lower beams are insulating plastic parts. [0003] In the past, the installation of the load switch required metal brackets for the crossbeam, and the material of the crossbeam was insulating plastic such as PC or nylon; this resulted in an increase in the weight, cost, and assembly time of the entire load switch. In the past, the bracket...
