Circuit breaker mechanism for solid insulated ring main unit

Abstract

The invention relates to the technical field of power system distribution switch equipment, particularly to a disconnector mechanism for a solid insulating ring main cabinet. The disconnector mechanism for the solid insulating ring main cabinet comprises a support rack is a frame structure; the support rack is provided with an energy storage operation assembly, a switch-on operation assembly and a switch-off operation assembly which are horizontally arranged; the energy storage operation assembly, the switch-on operation assembly and the switch-off operation assembly, by taking the support rack as a carrier, form a modular structure which can be integrally mounted on the solid insulating ring main cabinet and used for switching on and off the vacuum tube of the ring main cabinet. The disconnector mechanism for the solid insulating ring main cabinet obtains the operations of energy storage, switch-on and switch-off as well as the functions of automatic switch-on and switch-off counting, can achieve manual and electrical operations, and meanwhile, is compact in structure, space-saving and convenient to mount and maintain.

Description

technical field [0001] The invention relates to the technical field of power system distribution network switchgear, in particular to a circuit breaker mechanism for a solid insulation ring main unit. Background technique [0002] At present, most of the solid-insulated ring main unit circuit breaker mechanisms on the market adopt the spindle rotation method, are arranged vertically, occupy a large space, have many mechanism parts, and cannot be pre-assembled into component modules. In addition, during the operation of opening and closing, the main shaft rotates to drive the swing arm on the main shaft to swing, and then drives the movable end of the vacuum tube to move. This movement method has some defects, because the swing of the crank arm has a radian, which will cause the movable end of the vacuum tube to move. The arc movement causes the vacuum tube to bounce, which will reduce the breaking performance. Contents of the invention [0003] The technical problem to be...
