This product is suitable for monitoring the density of SF6 gas in sealed containers. The gas density value can be displayed on site. When the gas density value reaches the preset value, the contact device will immediately send out an alarm and control signal. The effective execution of inflation, micro water measurement and calibration can be carried out without disassembling the SF6 gas density relay, preventing unnecessary leakage of SF6 gas during the process of inflation, micro water measurement and calibration. Widely used in SF6 insulated combined electrical appliances, circuit breakers, column switches, transformers and transformers and other electrical equipment. Provide solutions for new substations and intelligent transformation of existing substations.
