  • SF6 Gas Detection For HV GIS Switchgear - Crowcon F-Gas Detector

    Sep 30, 2020 · SF6 gas has virtually replaced oil and air as the dielectric insulator in medium (MV) and high (HV) circuit breakers, switchgear, gas-insulated substations and electrical equipment. Despite SF6 being an inert gas during normal use, when electrical discharges occur through the operation of high voltage equipment insulated with SF6, highly toxic by-products are produced that pose a serious health threat to workers.

  • Ring Main Unit Gas Leakage Problem - Rockwill Electric Group

    There are 14 methods to detect gas leakage in the ring main unit. (1) Soap bubble method: Wipe the soapy liquid at the suspected point, check whether there is bubble, thus distinguish whether there is SF6 gas leakage. Pros and cons: The monitoring method is simple and clear, which does not require expensive instruments and equipment, but the monitoring precision is poor, the monitoring is one-sided, and the monitoring period is long, which is not suitable for general measurement.

    It was reported in 2013 that a three-year effort by the United States Department of Energy to identify and fix leaks at its laboratories in the United States such as the Princeton Plasma Physics Laboratory, where the gas is used as a high voltage insulator, had been productive, cutting annual leaks by 1,030 kilograms (2,280 pounds). This was done by comparing purchases with inventory, assuming the difference was leaked, then locating and fixing the leaks.

  • A precise ultra high frequency partial discharge location

    When it occurs inside the gas-insulated switchgear cavity, it degrades insulation, and, sooner or later, causes a breakdown. Therefore, it is important to discover insulation defects as early as possible, locate the discharge, and perform both defect identification and maintenance. Current ultra high frequency-based partial discharge location methods mainly use time delay.
