Abstract

The invention discloses a solid insulating isolating grounding switch, and relates to the technical field of manufacturing of high and medium voltage electric appliances. The solid insulating isolating grounding switch comprises an insulating shell in which an isolating switch and a grounding switch are arranged, wherein a static terminal part of the isolating switch consists of a bus terminal, an isolating switch insulating cylinder and a conducting terminal; a static terminal part of the grounding switch consists of a conducting terminal, a grounding switch insulating cylinder and a grounding terminal; the static terminal part of the grounding switch and the static terminal part of the isolating switch are provided with a mobile terminal common channel in which a common mobile terminal and an operating mechanism are arranged; and shielding covers are arranged on both sides of the two ends of the isolating switch insulating cylinder and the grounding switch insulating cylinder. According to the solid insulating isolating grounding switch, the problems of large solid insulating switch volume, many assembly steps, high probability of flashover in the switch and serious local discharge can be solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing medium and high voltage electrical appliances, in particular to a solid-sealed solid-insulation isolating grounding switch with a grounding layer coated on the surface of the insulating layer and used for a solid-insulation ring network cabinet. Background technique [0002] Solid insulated ring network cabinets are currently a hot spot in the development of ring network cabinets. As key equipment for urban network transformation and user power distribution equipment control, the quality of ring network cabinets is directly related to the safety and reliability of the power transmission system. Because SF6 gas has a superior arc-extinguishing effect, ring network cabinets insulated with SF6 gas are very common at present, but because SF6 gas is an unfriendly gas, its destructive power to the atmospheric ozone layer is equivalent to 23900 times that of CO2, such as Improper handling will aggr...
