Outdoor high voltage solid-sealed polar pole or recloser

Abstract

The invention discloses an outdoor high voltage solid-sealed polar pole or recloser which comprises a solid insulation shell, an upper wire inlet conductor, a capacitor, a vacuum arc-extinguishing chamber, a lower wire outlet conductor, a transition conductive connection part and a grounding layer. The solid insulation shell is provided with the upper wire inlet conductor, the capacitor, the vacuum arc-extinguishing chamber, the lower wire outlet conductor, and the transition conductive connection part. The grounding layer is arranged at the outer surface of the solid insulation shell. The upper and lower ends of the vacuum arc-extinguishing chamber are provided with upper and lower shielding rings. The lower end of the transition conductive connection part is provided with a shielding ring, and one side of the transition conductive connection part is also provided with temperature sensor. According to the outdoor high voltage solid-sealed polar pole or recloser, through introducing the design of the grounding layer, the shielding rings and the temperature sensor, the prepared outdoor high voltage solid-sealed polar pole or recloser can measure the current and voltage in a line, equipment is protected, the influence of an external environment is small, and thus the overall reliability stability and security are improved.

Description

technical field [0001] The present invention relates to the field of power equipment in power systems, in particular to outgoing line protection equipment used for power distribution lines, or used as line section protection equipment in the middle of power distribution lines and at the entrance of important branch lines, and in particular to a reliable outdoor high-voltage Solid-sealed pole or recloser. Background technique [0002] Existing outdoor high-voltage vacuum circuit breakers or reclosers usually adopt a solid-sealed pole structure. Since this product is usually used outdoors, it is greatly affected by the surrounding environment such as air pressure, humidity, density, dust, etc., so it usually requires a higher climb rate. Electrical distance requirements, so the overall shed more, the overall larger. In some areas with harsh environments, ultraviolet rays or acid and alkali are particularly strong and easy to damage the molecular chain of epoxy resin, thereby ...

AI Technical Summary

Problems solved by technology

The product is relatively large overall, with many external sheds, which occupy more materials and use space, and cannot be used to measure the voltage, power and electric energy of the line, or to protect the valuable equipment in the line when the line fails. In this product, there are many conductive parts such as flexible connections, which cannot guarantee its overall reliability. At the same time, because its solid insulating material is insulated by air, it is greatly affected by the external environment.
