The invention discloses a solid ring network cabinet, which includes a solid-sealed pole, and the solid-sealed pole includes an insulating jacket, three sets of vacuum switch tubes and an insulating pull rod assembly. The insulating jacket has an integrated structure, and the insulating jacket includes The lower casing and the three hollow tube parts arranged on the lower casing, the three sets of insulating pull rod assemblies are all set in the lower casing, the three sets of vacuum switch tubes are respectively set in the three hollow tube parts, and the three sets of insulating pull rod assemblies It is respectively connected with three sets of vacuum switching tubes; it also includes an isolation knife switch operating mechanism and a vacuum switch operating mechanism; the vacuum switch operating mechanism is connected with the moving contact of the vacuum switch tube to control the opening and closing of the vacuum switch; the isolation knife switch The operating mechanism is connected with the insulating pull rod assembly, and is used to drive the insulating pull rod assembly to move up and down. The invention is a solid ring network cabinet with small volume, no pollution and low requirements on the sealing performance of the cabinet body.
Description
technical field [0001] The invention relates to the technical field of solid ring network cabinets. Background technique [0002] At present, the country is building a smart grid, which includes: power generation, power transformation, power distribution, dispatching and automation of power consumption, etc. As an important link such as power distribution, scheduling, and power consumption, the ring network cabinet plays an important role in power distribution automation. [0003] The insulation medium of the ring network cabinet has gone through the process of air insulation, air and SF6 gas mixed insulation, SF6 gas full insulation, and finally solid insulation. [0004] The disadvantages of air-insulated ring network cabinets are: large volume, weak anti-pollution ability, and limited by the use environment; and the disadvantages of SF6 gas-insulated ring network cabinets are: SF6 gas pollutes the environment and is not environmentally friendly; the sealing requirements ...
