Description

Technical Field

[0001] The utility model relates to a primary-secondary fusion insulation ring network cabinet. Background Art

[0002] The primary and secondary integrated normal pressure sealed air insulated ring main unit is an advanced power distribution equipment, which uses air as the insulating medium to achieve the organic integration of primary and secondary equipment. While maintaining excellent insulation and arc extinguishing performance, the equipment avoids the pollution of SF6 gas to the environment. It is environmentally friendly, safe, intelligent and efficient, and is widely used in modern power distribution networks. The general ring main unit includes a mechanism cabinet room, a metering cabinet room, a busbar cabinet room, etc. Among them, the metering cabinet room is used for electric energy metering, and has built-in voltage transformers, current transformers and other related metering equipment. Therefore, it is often necessary to observe and open and close frequently. The existing metering cabinet room still uses a lock core to open. Since the metering cabinet room is placed at the top of the ring main unit, it is very inconvenient to operate and it is impossible to monitor the internal metering equipment in real time. Improvements and optimizations are made for this. Utility Model Content
