Abstract

A solid-insulated ring main unit comprises a fuse unit, an operation mechanism, a bus unit, a control room unit, a metal plate cabinet body, a pole column body, a visual window and a light-permeable window, wherein the visual window is formed in the front face of the metal plate cabinet body, the light-permeable window is formed in the pole column body at the back of the metal plate cabinet body, and the closing position of the visual window, the closing position of the light-permeable window and the closing position of an isolating switch share the same axis. According to the solid-insulated ring main unit, devices and connection relations which lower the overall reliability in existing product structures on the market are redesigned, complex linkage structures of various main parts are replaced, the man-machine interaction characteristics of equipment are improved, the defects of existing linkage structures on the market are overcome, safety and reliability are improved, and the cost is lowered.

Description

technical field [0001] The invention relates to a high-voltage power supply device, in particular to a high-voltage switchgear for ring network power supply. Background technique [0002] Solid insulated ring network cabinets need to meet high-level industry standards and national standards to ensure reliability. In order to meet various mandatory national standards, ring network cabinets on the market continue to adopt improvement measures to overcome technical defects, gradually dissimilating the overall structure of ring network cabinets, and lack of unified design ideas between new and old modules, making the overall usability unreachable Guarantee, operability and human-computer interaction structure are often counterintuitive, and the maintenance personnel in the long-term operation and maintenance process of the equipment are extremely unfriendly and have low security. [0003] The existing solid insulated ring network cabinet mainly reflects the influence of targete...
