Transformation of SF6 density relay in Wevers-Feng

Recently, Weavers and Chengde Power Supply Company 110kv substation SF6 density relay renovation, SF6 density relay installed three-way valve, and successfully, strengthen the safety and reliability of SF6 electrical equipment in the power station.

SF6 density relay online calibration system is not changing any of the original structure of the switch, through the switch SF6 density relay interface, add a combination valve with a breaking device, The valve is provided with a connector for the original SF6 density relay interface, a SF6 density relay connector, a breaking device and a connector for a special SF6 density relay calibrator. After the connection is made according to the design requirements, the gas path of SF6 density relay and the gas path of switch body can be realized by rotating the breaking device. When it is necessary to verify the SF6 density relay, it is necessary to rotate the breaking device on the valve body to the closed state, and then complete the connection between the calibrator interface and the calibration interface reserved on the valve body, so as to realize the calibration of SF6 density relay, which can greatly save the precious time of maintenance personnel. It can also greatly reduce the risk of SF6 gas leakage due to regular verification disassembly.

The density relay transformation carried out by Weavers for the 110kv substation of Chengde Power Supply Company has enhanced the safety and reliability of SF6 electrical equipment and played a key role in the power supply optimization of the 110kv substation of Chengde Power Supply Company.
