Method for manufacturing 500kV isolation switch

Abstract

The invention discloses a method for manufacturing a 500kV isolation switch. The method comprises the following steps of: installing an insulator on a base, and well setting a conductive loop on the base, such that an isolation switch body is manufactured; fixing a wiring board on the isolation switch body by using a bolt, wherein the static safety factor of the wiring board is not less than 3.5; and the wiring board can bear 1000N*m bending moment and cannot be deformed; then, connecting an operation mechanism, auxiliary equipment, a horizontal operation connecting rod and a vertical operation connecting rod onto the isolation switch body, wherein the output shaft and the transmission shaft of the operation mechanism are in transmission connection; a universal bearing and shaft sleeve connection having a self-lubricating function are adopted in the transmission connection; and a shaft pin of the universal bearing is made of an aluminium bronze material; and finally, connecting an induced current turn-on / turn-off device onto the isolation switch body. The advantage that the equipment failure rate is reduced can be realized.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a method for manufacturing a 500kV isolating switch. Background technique [0002] At present, the planned maintenance system adopted by most of the power equipment in the power system has serious defects, such as frequent temporary maintenance, insufficient or excessive maintenance, blind maintenance, etc., which makes countries around the world spend a lot of money on equipment maintenance every year. For a long time, my country's power system has implemented a regular maintenance system for power equipment, that is, equipment is tested and maintained according to the planned time period, so there are disadvantages of over-maintenance and under-maintenance. A fault in the power system often causes a large-scale power outage. However, existing power equipment has a relatively high failure rate. Contents of the invention [0003] The object of the present invention is to pro...

[0002] At present, the planned maintenance system adopted by most of the power equipment in the power system has serious defects, such as frequent temporary maintenance, insufficient or excessive maintenance, blind maintenance, etc., which makes countries around the world spend a lot of money on equipment maintenance every year

For a long time, my country's power system has implemented a regular maintenance system for power equipment, that is, equipment is tested and maintained according to the planned time period, so there are disadvantages of overhaul and insufficient maintenance

Due to a fault in the power system, it often causes a large-scale power outage

However, the existing power equipment has the problem of relatively high failure rate.
