Fully sealed solid insulated switch insulation cover

Abstract

The invention discloses a fully-sealed solid insulating switch insulating cover. The insulating cover is in a cuboid shape, one side wall of the insulating cover is provided with a first interface and a second interface from top to bottom, the opposite side wall of the insulating cover is provided with a first pull rod through hole and a second pull rod through hole from top to bottom; a three-position switch cavity is arranged in the insulating cover, the first interface and the first pull rod through hole are respectively communicated with the three-position switch cavity; and a second pull rod groove and a vacuum foam groove are respectively arranged in the insulating cover, and the top of the insulating cover is covered with a transparent cover. The insulating cover disclosed by the invention can correctly master whether an isolating switch separating brake is in a safe distance, and is especially applicable to an upper isolation and lower isolation scheme.

Description

technical field [0001] The invention relates to switchgear, in particular to a fully sealed solid insulation switch insulation cover. Background technique [0002] In the prior art, 10-35kV ring network switchgear is mostly SF6 inflatable switch, which will produce toxic gas to pollute the environment after arc extinguishing, and SF6 gas will produce a greenhouse effect; most of the switch structure gas boxes are welded by steel plates. The production process is complicated, and it is usually difficult to observe whether the isolation switch has been opened, which brings safety hazards to the operator. The sealing ring is used for a long time and will cause gas leakage after aging. It is difficult to see the closing and opening states of the switch, and it is difficult to determine whether the fracture has reached a safe distance after seeing it; when using the upper isolation or lower isolation scheme, two sets of different switchgear must be used, which is costly and infle...

Problems solved by technology

[0002] In the existing technology, most of the 10-35kV ring network switchgears are SF6 inflatable switches, which will produce toxic gas to pollute the environment after arc extinguishing, and SF6 gas will produce a greenhouse effect; most of the gas boxes of the switch structure are welded by steel plates. The production process is complicated, and it is usually difficult to observe whether the isolating switch has been opened, which brings safety hazards to the operator. The sealing ring is used for a long time, and the gas will leak after aging; It is difficult to see the closed and open state of the switch, and it is difficult to determine whether the fracture has reached a safe distance after seeing it; when using the upper isolation or lower isolation scheme, two different sets of switchgear must be used, which is costly and inflexible in manufacturing
