Description
technical field [0001] The invention relates to a 10kV sulfur hexafluoride gas pressure relief ring network cabinet, which belongs to the technical field of power distribution equipment. Background technique [0002] At present, the insulation of 10kV ring main unit is mainly based on gas insulation, return body insulation and environment-friendly gas insulation. Gas insulation is currently mainly SF6 gas. SF6 gas has very stable chemical properties and has excellent insulation and arc extinguishing properties. SF6 gas-insulated ring network cabinets are small in size, compact in structure, and extremely adaptable. [0003] For traditional gas ring network cabinets, for the 10kV power distribution project indoor sulfur hexafluoride gas ring network cabinet, the pressure relief port of the switch is located in the middle and lower parts and the middle and upper parts. Then the pressure is released from the pressure relief port; when the pressure relief port releases the pres...
