Abstract

The invention relates to a GIS voltage sharing capacitor which comprises an insulating cylinder. An upper connecting conductive cover and a lower connecting conductive cover are respectively arranged on the two ends of the insulating cylinder, and a sealing cavity is formed in the insulating cylinder through the upper connecting conductive cover and the lower connecting conductive cover. A voltage sharing capacitor body and an expander are arranged in the sealing cavity. One end, of the voltage sharing capacitor body, adjacent to the upper connecting conductive cover is electrically connected with the upper connecting conductive cover, and the end, of the voltage sharing capacitor body, adjacent to the lower connecting conductive cover is electrically connected with the lower connecting conductive cover. The loss of the voltage sharing capacitor is effectively reduced, the production cost is lowered, and the work efficiency is improved. Voltage sharing effect is achieved during on / off of a GIS switch, micro-positive pressure state of the GIS voltage sharing capacitor is retained, and oil leakage and oil shortage of the GIS voltage sharing capacitor are effectively minimized. Partial discharge is reduced, and properties of the GIS voltage sharing capacitor are stabilized, so that the GIS voltage sharing capacitor can safely and stably operate in a power grid for a long time, and normal power consumption of users can be ensured.

Description

technical field [0001] The invention relates to a voltage equalizing capacitor, in particular to a GIS voltage equalizing capacitor, which belongs to the technical field of fixed voltage equalizing capacitors. Background technique [0002] With the development of the economy, the power consumption of the power grid is increasing day by day. GIS equipment has been widely used all over the world since it was put into practical use in the 1960s. GIS is not only widely used in the field of high voltage and ultra-high voltage, but also in the field of ultra-high voltage. Compared with open substations, GIS has the advantages of compact structure, small footprint, high reliability, flexible configuration, convenient installation, strong environmental adaptability, and small maintenance workload. The maintenance interval of its main components is not less than 20 years. GIS voltage equalizing capacitor is an important part of GIS equipment, which provides voltage equalization fun...
