Embodiment

[0026] Such as figure 1 and as figure 2 As shown, the present invention provides a SF6 gas chamber interface device for GIS combined electrical equipment, which includes a base body 10 and an air intake operating part. The base body 10 is arranged at the SF6 gas chamber port and is connected with the SF6 gas chamber port. The base body 10 is circular The cover is provided with at least two fixing holes 13 on the circular cover, the fixing holes 13 are provided with threads, the fixing holes 13 are equipped with screws, and the screws fix the substrate 10 on the SF6 air chamber mouth.

[0027] A sealing ring 12 is provided on the side where the substrate 10 is connected to the SF6 gas chamber port, and the sealing ring 12 is a rubber sealing ring 12. When the substrate 10 is fixedly connected to the SF6 gas chamber port, the sealing ring 12 is squeezed and the sealing ring 12 is deformed. And increase the airtightness of the connection between the substrate 10 and the SF6 air...

Abstract

The invention relates to the technical field of power equipment maintenance, and more particularly, to a GIS combined electrical equipment SF6 gas chamber interface device, which comprises a base bodyand a gas taking operation member, wherein the base body is connected with an SF6 gas chamber port, the base body is provided with an opening matched with the SF6 gas chamber port, and the SF6 gas chamber port is provided with a non-return valve; the gas taking operation member comprises a gas taking interface and an unlocking member, a connecting member is arranged between the gas taking interface and the unlocking member, an adjusting member is arranged on the connecting member, and the adjusting member can slide relative to the connecting member; the connection place between the connectingmember and the unlocking member is provided with a limiting structure for limiting the adjusting member; and the unlocking member is in threaded connection with the opening of the base body. The problems of low working efficiency and low safety caused by the traditional repeated assembly and disassembly can be solved, and the gas taking process flexibility is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of power equipment maintenance, and more specifically, to a SF6 air chamber interface device for GIS combined electrical equipment. Background technique [0002] GIS combined electrical equipment is a gas-insulated metal-enclosed switchgear that uses SF6 gas as an insulating medium. Due to its reasonable structure, small footprint, high operational reliability, small maintenance workload, and long maintenance cycle, it is not affected by external environmental conditions. No static induction and corona interference, low noise level, good shock resistance, strong adaptability, etc., widely used in the power industry. [0003] GIS equipment needs to maintain the SF6 gas inside the gas chamber regularly, and the SF6 gas needs to be extracted or injected through the gas chamber interface. For the GIS equipment whose air chamber interface is a circular double-screw fastening structure to carry out SF6 gas mainte...
