Abstract

The invention belongs to the technical field of capacitors and discloses a voltage-sharing capacitor. The voltage-sharing capacitor comprises an insulating bush, an expander and a capacitor element assembly, wherein the expander and the capacitor element assembly are arranged in the bush; an upper end cover is arranged at the top end of the insulating bush; a lower end cover is arranged at the bottom end of the insulating bush; a top inflation hole is formed in the upper end cover and is a stepped threaded hole; a bottom oil injection hole is formed in the lower end cover; a bottom sealing cover is arranged in the bottom oil injection hole; the expander is arranged above the capacitor element assembly; the expander is fixed on the upper end cover; an expander cover is arranged outside theexpander; wires are led out from two ends of the capacitor element assembly; and one end of the capacitor element assembly is connected with the expander, and the other end of the capacitor element assembly is connected with the lower end cover. The voltage-sharing capacitor is compact in structure and good in sealing performance and insulating performance. The inflation hole is sealed by means ofa one-way inflation mode, so that the air tightness of the whole capacitor can be guaranteed; filling paper boards and a buffer pad are adopted and can bear large mechanical vibration and impact loadin operation or transportation, and therefore, the stability of the capacitance of the product is ensured.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a voltage equalizing capacitor. Background technique [0002] With the development of the economy, the power consumption capacity of the power grid is increasing day by day. The voltage equalizing capacitor equipment is not only widely used in the high voltage and ultra high voltage fields, but also in the ultra high voltage field. The voltage equalizing capacitor is mainly used to improve the unbalanced voltage distribution between the breakers, reduce the rate of recovery voltage rise, and improve the breaking capacity and overall insulation level of the circuit breaker. However, there is still a lot of room for improvement in the important performance sealing performance and insulation performance of voltage equalizing capacitors in the prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a voltage equali...
