Totally-enclosed solid-sealed polar pole

Abstract

A totally-enclosed solid-sealed polar pole comprises an epoxy resin pouring block, a vacuum extinction chamber and a vacuum disconnecting switch, wherein the vacuum extinction chamber and the vacuum disconnecting switch are arranged in the epoxy resin pouring block; a fixing contact of the vacuum extinction chamber is connected with a first wire incoming and outgoing casing pipe; the first wire incoming and outgoing casing pipe is arranged at the side of the epoxy resin pouring block; a moving contact of the vacuum extinction chamber is linked with a first draw bar; a fixing end of the vacuum disconnecting switch is connected with a second wire incoming and outgoing casing pipe; the second wire incoming and outgoing casing pipe is arranged at the side of the epoxy resin pouring block; the moving end of the vacuum disconnecting switch is linked with a second draw bar; the moving end of the vacuum disconnecting switch is in flexible connection with the moving contact of the vacuum extinction chamber; and the upper ends of the first draw bar and the second draw bar extend out of the epoxy resin pouring block. According to the totally-enclosed solid-sealed polar pole, the insulating capacity can be improved, the protection level is higher and the potential safety hazard can be effectively eliminated.

Description

technical field [0001] The invention relates to a solid-sealed pole of a ring network cabinet, in particular to a solid fully-enclosed pole of a medium-voltage AC power distribution all-solid insulation ring network cabinet. Background technique [0002] In the prior art, the solid-sealed pole is to embed the vacuum interrupter and the conductive parts related to the circuit breaker into an easily curable solid insulating material such as epoxy resin to form a pole, so that the entire circuit breaker pole becomes a integral parts. The existing technology usually only casts the vacuum interrupter and related conductive parts together, but there is no way for the three-position isolating switch to be cast together with the vacuum interrupter, which seriously hinders the development of the real solid cabinet . Contents of the invention [0003] In order to overcome the shortcomings of the existing all-solid insulated ring network cabinets, such as poor insulation capability...
