Abstract

The invention relates to a power capacitor unit, comprising a capacitor case and a capacitor core, the capacitor core is placed in the middle of the capacitor case, between the capacitor core and the capacitor case and inside the capacitor core There are corrugated mufflers in the middle. Compared with the prior art, the invention has a simple manufacturing process, has little influence on the electrical performance of the capacitor, can reduce the noise radiation level, has low cost, and is suitable for large-scale application.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a power capacitor which adopts an armored mute shell and a corrugated muffler to reduce noise radiation. Background technique [0002] The direct current transmission project plays a very important role in solving the imbalance of energy distribution between the east and the west in my country and realizing long-distance power transmission. In recent years, with the rapid development of DC transmission technology in my country, DC transmission accounts for an increasing proportion of my country's power energy transmission. After 2000, more than 10 new DC projects have been put into operation in my country, and the voltage level of the system has rapidly developed from ±500kV to ±1100kV. [0003] With the development of my country's economy and the improvement of people's living standards, the country's requirements for environmental protection have been increasing year by...
