Outdoor high-voltage isolation energy-taking capacitor structure

Abstract

An outdoor high-voltage isolation energy-taking capacitor structure comprises an insulation tube, wherein two ends of the insulation tube are sealed with a short-diameter cover plate and a long-diameter cover plate respectively; a spring, a high-voltage fuse and a high-voltage capacitor are mounted in the insulation tube sequentially from the short-diameter cover plate to the long-diameter cover plate; the outer wall of the insulation tube is sleeved with an insulation sleeve; more than one umbrella-shaped skirt structure is arranged on the periphery of the insulation sleeve; and the umbrella-shaped skirt structures are arranged at intervals in the axial direction of the insulation sleeve. According to the outdoor high-voltage isolation energy-taking capacitor structure, the insulation tube is sleeved with the insulation sleeve, and the umbrella-shaped skirt structures are arranged on the outer wall of the insulation sleeve, so that the creep distance of a high-voltage capacitor can be increased greatly, the problem that the insulation degree of an outdoor distribution network line monitoring device is insufficient due to damp climate, heavy rain, salt fog and air pollution when outdoor distribution network line monitoring device are subjected to high-voltage energy-taking and the problem that the insulativity is damaged under the condition of a very low temperature in an extremely cold area are solved, the electrical performance is good, the mounting is convenient, and the service life is long.

Description

Technical field: [0001] The invention relates to the field of electricity, in particular to a technology for obtaining electric energy of a high-voltage power monitoring system, in particular to an outdoor high-voltage isolation energy-taking capacitor structure. Background technique: [0002] In smart distribution network technology, the monitoring system uses high-voltage isolation energy harvesting capacitors to obtain electrical energy. In the prior art, outdoor high-voltage isolation energy harvesting capacitors are made by simply wrapping epoxy resin outside high-voltage fuses and high-voltage capacitors. However, in winter in extremely cold regions, the epoxy resin wrapped around high-voltage capacitors cracks due to low temperature, resulting in The surface insulation strength of the outdoor high-voltage isolation energy harvesting capacitor is greatly reduced, and it may cause surface breakdown after falling off, posing a potential accident.
