Benefits of technology

This patented technology allows for faster testing of sulfhexaniline (SF 6) concentration meters at different locations within an electric power system or transformer station. It also includes various technical features such as automatic shutdown functions, remote communication capabilities, and leakage detection systems. These improvements make it safer during operation while ensuring accurate measurement results.

Problems solved by technology

The technical problem addressed by this patented technology is how to quickly measure the concentration of gases used within electricity systems such as Sulfursulfur hexafluidum while minimizing any risks associated with testing or inspecting these materials during installation. Current methods involve bulky devices attached to the system being tested, making them hard to use safely due to their size and weight.

Abstract

The invention relates to a rapid verification method and device for a non-dismountable sulfur hexafluoride density relay. The device comprises first sulfur hexafluoride gas insulation equipment (1), second sulfur hexafluoride gas insulation equipment (5), a first gas sampling connector and valve (2), a second gas sampling connector and valve (6), a first density relay (3), a second density relay (7), a first density relay verification valve (4), a second density relay verification valve (8), a verification connector (9) and a rapid density relay verification platform (10). The device is advantaged in that the adjacent high-altitude sulfur hexafluoride density relays can be integrated on the platform arranged on the ground, climbing risk can be greatly reduced, all the density relays concentrated on the platform can be verified completely through a valve control method without dismounting the verification connectors, the time is substantially saved, and emission of sulfur hexafluoride gas having the greenhouse effect can be prevented.
