Abstract

The invention discloses a high pressure capacitor component which includes more than one block of aluminum plates that are arranged by layers; more than one bare capacitor arranged on each layer of aluminum plate; more than one equalizing resistance arranged on each bare capacitor and more than one insulating part arranged between each layer of aluminum plate to carry out supporting. The invention can work under a high pressure gas atmosphere, in particular to SF6 gas environment; the pressure-proof capacity of the invention is higher and is the invention is convenient to be connected.

Description

technical field [0001] The invention relates to a capacitor assembly, in particular to a high-voltage capacitor assembly. Background technique [0002] Most of the existing polyester film capacitors with high withstand voltage and large capacity adopt a fully sealed structure. It cannot be used in a high-pressure gas environment, so the voltage it can withstand is also limited. However, if an unsealed bare capacitor is used, it is relatively difficult to use it in terms of mechanical connection and electrical connection. Contents of the invention [0003] The object of the present invention is to provide a high-voltage capacitor assembly that can work in a high-pressure gas environment, which has high withstand voltage capability, large capacity and convenient connection. The purpose of the present invention is achieved through the following technical solutions: [0004] A high voltage capacitor assembly comprising: [0005] More than one aluminum plate arranged in lay...
