sf6 infrared leak detection auxiliary tool

Abstract

The invention relates to an SF6 infrared leakage detection assistant tool, which includes a base. A fan is installed in the middle part of the base, and air outlets are respectively arranged on two sides of the fan. The bottom part of the base is connected with a handle, and the top part of the base is connected to two air supply pipes capable of folding to an integration in hinge. The air outletsarranged on the two sides of the fan are respectively connected with the bottom parts of the two air supply pipes through flexible air outlet pipes. Two ends of the air supply pipes are close and theinvolution surfaces of the two air supply pipes are planes; a plurality of air supply holes are respectively arranged on the two corresponding involution surfaces and two corresponding air supply holes are communicated with each other when the air supply pipes are folded; wherein the top end of one air supply pipe is connected to a metal setting hose, and a lateral air outlet is arranged on the top end of the metal setting hose. The SF6 infrared leakage detection assistant tool solves the problem of lacking air in the SF6 leakage detection and has the advantages of easy whole structure, convenient maneuvering and sound detection effect.

Description

technical field [0001] The invention relates to the field of SF6 equipment leak detection, in particular to an auxiliary tool for SF6 infrared leak detection. Background technique [0002] SF6 (sulfur hexafluoride) is an insulating medium, its dielectric strength is 2.33 times that of air, and its arc extinguishing ability is 100 times that of air, so SF6 is generally used as an insulation and arc extinguishing medium for high-voltage electrical equipment. [0003] For SF6 equipment, the leakage of SF6 gas will seriously affect the operation safety of the equipment. Therefore, regular testing of SF6 equipment is required. SF6 leak detection generally uses SF6 infrared leak detector. In actual detection, SF6 infrared leak detection requires a breeze in the environment and a suitable wind direction. If there is no breeze in a suitable wind direction, the smoke generated by SF6 leakage cannot be seen under the SF6 infrared leak detector. gas. The current GIS combined equipmen...

Problems solved by technology

SF6 leak detection generally uses SF6 infrared leak detector. In actual detection, SF6 infrared leak detection requires a breeze in the environment and a suitable wind direction. If there is no breeze in a suitable wind direction, the smoke generated by SF6 leakage cannot be seen under the SF6 infrared leak detector. gas

The current GIS combination equipment is arranged indoors, and the air circulation is not smooth, so it is difficult to accurately detect SF6 leakage
