Modular solid insulation ring network cabinet

Abstract

The invention discloses a modular solid insulation ring network cabinet which comprises a cabinet body, an insulated bus module, an isolation module, a main body module, a grounding module and an operating mechanism for controlling the main body module and the grounding module to actuate, wherein the operating mechanism is arranged on the side wall of the cabinet body, the main body module is connected with the operating mechanism through an insulated pull rod, the grounding module is arranged below the main body module, the grounding module is connected with the operating mechanism through a grounding pull rod, the isolation module is arranged at the right lower side of the grounding module, the isolation module comprises an isolation blade and an isolation pull rod movably connected with the isolation blade, and the isolation pull rod is movably connected with a rotating swing rod at the bottom of the operating mechanism. By adopting the modular design, the modular solid insulation ring network cabinet is flexible in production process, convenient to mount and maintain, and compact in structure and small in size as a fully-sealed structure is adopted in the mounting process; and in addition, the modular solid insulation ring network cabinet is provided with a working state monitoring device which can be used for avoiding an electric shock risk, thereby being high in safety.

Description

technical field [0001] The invention relates to the field of high-voltage switches, in particular to a modular solid insulation ring network cabinet. Background technique [0002] The ring network cabinet is a kind of electrical equipment commonly used in ring network power supply. Its core components are load switches and fuses. Important switchgear for ring mains power supply and terminal power supply. [0003] Recently, most of the ring network cabinets on the market are air-insulated ring network cabinets and SF6-insulated ring network cabinets. Among them, air-insulated ring network cabinets have been gradually eliminated due to their large volume, high cost, and large space occupation. The SF6 insulated ring network cabinet has an SF6 switch inside. SF6 is an inert greenhouse gas that is easily mixed with toxic gases such as sulfur fluoride. Therefore, the supervision of its use is gradually strengthened. On the other hand, with the maturity of vacuum switch technolo...
