Abstract

Provided is an SF6 online automatic density adjustment device, which comprises an SF6 electrical module A. The SF6 electrical module A comprises an SF6 electrical device 1, a density relay 15, a solenoid valve 16, a joint 17, a pressure sensor 18 and a temperature sensor 19. The SF6 online automatic density adjustment device also comprises a density adjustment module B and a control communicationmodule C. The density adjustment module B of the SF6 online automatic density adjustment device can solve the problem of possible gas leakage in the gas filling and releasing process due to low density and high density, and automatic processing of a small amount of gas filling and releasing is realized.

Description

Technical field [0001] The invention relates to an SF6 online automatic density adjustment device, which belongs to the field of SF6 electrical equipment. Background technique [0002] At present, during the operation of SF6 electrical equipment, the leakage of SF6 gas inside the SF6 electrical equipment due to the aging of the seals and the calibration of SF6 density relays causes the pressure and density of the SF6 gas to decrease, which leads to a decrease in the insulation performance of the SF6 gas. Causes hidden dangers to the safe operation of SF6 electrical equipment, or changes in the internal air pressure of SF6 electrical equipment due to external temperature changes, resulting in accidental alarms by SF6 density relays. Generally, the current conventional solution for the above situations is to add gas when the gas density is insufficient The method of deflation or recovery is adopted for high density. Generally speaking, it is more troublesome to recover the gas. At ...
