Embodiment 1

[0012] As shown in the above-mentioned drawings, a circular hole is opened on the front of the insulation box 1 of the solid insulation ring main unit, and the center of the hole is at the same height as the center line of the load switch static cutter head 11. The viewing piece 8 is cylindrical with a boss. The observation piece 8 is made of transparent, insulating, high and low temperature resistant, and explosion-proof materials. The observation piece 8 is provided with a refracting mirror 13 . The angle 18 between the refracting mirror surface 13 and the bottom of the observation piece is 50-60 degrees, and the height of the refracting mirror surface 13 does not exceed the center line of the observation piece 8 . Two light-emitting diodes are embedded in the observation piece 8, wherein the load switch knife in the horizontal direction illuminates the diode 15, and the other vertically downward ground knife illuminates the diode 14, which are used to provide illumination f...

Embodiment 2

[0017] Embodiment 2: The observation piece 8 passes through the mould, and is molded at one time by an injection molding process. All the other are with embodiment 1.

Abstract

The invention discloses a high-voltage switch refraction observation window used for observing the switch state of a solid insulation ring network cabinet. The high-voltage switch refraction observation window comprises a barrel-shaped observation part with a boss, and an observation barrel connected with the observation part, wherein the observation part is provided with a refraction mirror surface; the included angle between the refraction mirror surface and the bottom of the observation part is 50-60 degrees; the height of the refraction mirror surface does not exceed the central line of the observation part; a horizontal load switch blade irradiation diode and a vertical downward ground blade irradiation diode are fixedly packaged in the observation part; a seal groove used for mounting an O-shaped seal ring is formed in the table surface of the observation part; the rest part of the observation part is a barrel with a bottom; a thread is arranged on the outer edge of the barrel. According to the high-voltage switch refraction observation window, only an observation hole needs to be formed in an insulation box, so that the influence on the strength and screening of the insulation box is reduced; the observation part is made from a transparent insulated material and the light-emitting diodes are fixedly packaged in the observation part, so that the volume is reduced and the influence on electrical field distribution in the insulation box is reduced.

Description

technical field [0001] The invention relates to a high-voltage switch refraction observation window used for observing the switch state of a solid insulation ring network cabinet, and belongs to the technical field of medium-voltage switches. Background technique [0002] In order to ensure the safety of power operation, power system operators hope to directly observe the opening and closing status of switches. Some domestic switchgear companies have also carried out some research and achieved some results. For example, Patent Publication No. CN103414111A introduces an observation window lighting device for a solid insulated ring main unit, and two groups of observation windows and lighting devices are provided. Patent Publication No. CN202737330U introduces a switchgear with a reflective observation window, which forms reflective imaging through the cooperation of cylindrical mirrors and plane mirrors to achieve the purpose of observing the state of equipment in the switch...
