Abstract

The invention discloses a 110kV AC gapless metal oxide arrester assembly method, which comprises the steps as follows: an arrester body is arranged on an insulating base and comprises a porcelain jacket and a synthetic insulating jacket, wherein the synthetic insulating jacket wraps the outer surface of the porcelain jacket; an equalizing capacitor is arranged at the top part of the porcelain jacket; pressure release devices are arranged at two ends of an arrester; and an action and leakage current monitor is arranged on the arrester. The advantage of reducing the equipment failure rate is achieved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a method for assembling a 110kV AC gapless metal oxide arrester. 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 purpose of the present invent...
