Description
Technical Field
The invention relates to the technical field of SF6 gas detection, in particular to an SF6 gas detection auxiliary device for a switch porcelain bottle.
Background
SF6 is widely used in power systems, mainly in circuit breakers, CT, PT and other devices. Because the device runs outdoors for a long time, the air tightness is insufficient after the device runs outdoors for a long time, SF6 is leaked, and the device is damaged to influence the safe operation of a power grid. When SF6 leakage occurs, it is one of very difficult works to check the SF6 leakage point on site. Taking the check of the SF6 leakage point of the 35kV switch porcelain bottle as an example, the leakage point usually appears between the porcelain bottle and the flange joint, and is very tiny, the leakage point cannot be detected by infrared detection equipment, at this time, after the porcelain bottle and the flange are wrapped by a plastic film, the leakage point is checked for 0.5h or more until the leakage point is tightly attached to the surface of the porcelain bottle or the flange by a handheld SF6 detection instrument (a non-optical instrument); the method is very effective, but the manual skill of the wrapping is very detailed in the film wrapping process, the wrapping needs 1-2 hours for one time, and the problems of leakage detection and repeated work that the wrapping is waited again after the air tightness is not good exist. The inspection process is toxic in one hour on site, so that it is necessary to inspect whether the insulator is tightly connected with the transformer connection part in the maintenance process. Because the space that the transformer is located is spacious in the current transformer maintenance process, a small amount of SF6 gas leakage very diffuses easily, and special sensor is difficult to the accurate detection, leads to unable very first time discovery gas leakage. Potential safety hazards are left for production and maintenance of the transformer substation, and personal safety and property safety are endangered. Therefore, a portable transparent insulator sealing cover capable of being sealed randomly is urgently needed to be designed, the insulator and the connecting joint thereof above the transformer can be tightly packaged from the side edge, the space to be detected is reduced, and the accuracy of sensor identification is improved.
