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.

The invention discloses a sulfur hexafluoride decomposition product gas pressure monitoring device based on gas in-situ detection. The device comprises a gas circuit part, a detection part and a power supply part; the gas circuit part comprises a gas supplementing pipeline, a gas using pipeline, a testing pipeline, a reference pressure inflation valve, a reference pressure locking valve and a reference pressure cavity; the detection part comprises a differential pressure sensor, a differential pressure display meter, a pressure sensor and a reference pressure display meter; and the power supply part supplies power to the detection part. In a transformer substation field environment with violent temperature and humidity changes, the pressure of SF6 gas components can be continuously monitored for a long time under the condition that the operation state of SF6 gas insulation equipment is not interfered, so that a corresponding test basis is provided for perfecting an SF6 decomposition theory and a chemical diagnosis technology of electrical equipment.
