Abstract

The invention discloses a prismatic joint clamping device for an SF6 gas test of a GIS combined electric facility. The joint clamping device is used to communicate a prismatic gas chamber joint and atest joint and comprises a clamp connection member, a matching member, and a fastening member. The clamp connection member is connected to the prismatic gas chamber joint. The matching member is provided with a channel, which communicates the prismatic gas chamber joint and the test joint. The fastening member and the clamp connection member are connected through threads. The fastening member is used to push the connection between the matching member and the prismatic gas chamber joint. The joint clamping device is suitable for a prismatic gas chamber joint; a spiral locking structure is usedto replace a screw fastening mode, during the using process, only one fastening screw of the prismatic gas chamber joint is disassembled, the joint clamping device is connected to the gas chamber joint, then an air duct is leaded out through a second port, a test can be carried out; after the test, only one fastening screw is installed, the time for assembling and disassembling screws frequently during the test process is saved, a large amount of assembly-disassembly time is saved, the test process is optimized, and the test efficiency is improved obviously.

Description

technical field [0001] The present invention relates to SF 6 The gas test device particularly relates to a prismatic joint clamping device for SF6 gas test of GIS combined electrical equipment. Background technique [0002] GIS combined electrical equipment is the use of SF 6 Gas-insulated metal-enclosed switchgear with gas as the insulating medium, due to its reasonable structure, small footprint, high operational reliability, small maintenance workload, long maintenance cycle, is not affected by external environmental conditions, and has no electrostatic induction and corona interference. Low noise level, good anti-seismic performance, strong adaptability, etc., are widely used in the power industry. [0003] SF 6 Gas test (including humidity test and gas decomposition product test, etc.) is a must-test item for GIS combined electrical equipment. 6 Condition of gas and equipment. At present, the air chamber interface of GIS combined electrical equipment usually adopts...
