Description

technical field [0001] The invention belongs to electric power equipment vibration reduction technology in the field of electric engineering, and in particular relates to a power capacitor with a core vibration reduction device. Background technique [0002] The power capacitor is an important equipment in the power transmission and transformation system of the substation. Its main function is to compensate the reactive power of the line, improve the power factor to improve the power supply quality, limit the voltage rise, protect the electrical equipment, reduce line loss and maintain reactive power. balance. With the rapid development of my country's economy and the improvement of people's living standards, the scale of the power grid is gradually expanding, and the requirements for power quality are getting higher and higher. The application of power capacitor banks in power systems is becoming more and more extensive. In order to improve the power factor of the line, su...

Problems solved by technology

[0004] In order to solve the problem of capacitor vibration and related noise, most of the relevant Chinese patents only focus on the removal of noise, and some noise reduction measures have been studied. Although they have a certain effect on reducing the external noise of the capacitor device, they are not helpful to the weakening and isolation of the internal vibration of the capacitor. , can not fundamentally solve the vibration problem

The literature search shows that the research and development specifically for the vibration reduction of the compensation capacitor bank core of the substation power equipment is still blank, so the development of related power capacitors with internal vibration reduction devices has become an urgent need
