1. The role of sf6 gas density meter and density relay The so-called density refers to the mass per unit volume of a specific substance under specific conditions. The SF6 pressure gas in the SF6 circuit breaker is sealed in a fixed container. It has a certain density value under the rated pressure at 20℃. Within the range of various allowable conditions for the operation of the circuit breaker, although the pressure of SF6 gas changes with temperature, the density value of SF6 gas is always the same. Because the insulation and arc extinguishing performance of SF6 circuit breakers depends to a large extent on the purity and density of SF6 gas, the detection and density monitoring of SF6 gas purity is particularly important. If an ordinary pressure gauge is used to monitor the leakage of SF6 gas, it will be difficult to distinguish whether the pressure change of SF6 gas is caused by the actual leakage or the change of the ambient temperature. In order to achieve the purpose of frequent monitoring of density, SF6 circuit breakers should be equipped with SF6 gas density meters or density relays. The SF6 gas density gauge meter is for monitoring, and the density relay is for control and protection.

SF6 Gas Measurement Valves Our valve is a SF6 density relay connection with SF6 gas chamber, after complete assembly can make the power maintenance personnel don't remove this device, you can to check or replace SF6 gas density relay, thoroughly solved the relay check, change and remove the problem of tonifying qi, avoided due to periodically remove the joint in the process of checking result in the damage to the switch seal face and sealing ring, greatly reduces the leakage probability, improve work efficiency, ensure the safety of SF6 electrical switch operation.
