SF6 Gas Disconnector

General Information

SF6 Gas Separators are sealed in an epoxy resin cast body, with a “sealed pressure system”; It has 3 poles and 3 positions. EFG brand SF6 Gas Separators, which are filled with SF6 gas at 1.5 bar pressure at a pressure of 1.5 bar, can operate at 10.5 pressure, and whose gas tightness is checked in the production area and presented to the consumer company, are designed in a sealed pressure structure that does not require SF6 gas supplementation for 30 years, in accordance with TS EN 62271-102 standard.

In the event that the SF6 gas pressure unexpectedly rises to a dangerous level during operation, a pressure relief valve (weakened area) is located on the rear cover of the separator body to ensure that the gas is discharged in a way that does not pose a hazard to the operating personnel.

Closing and opening operations are performed manually in the EFG brand Gas Separator mechanism. The closing and opening process of the earthing switch is completed depending on the operator’s action. The operating mechanism is supervised by position indicators that reliably show the open and closed positions of the contacts. As standard, 3NO+ 3NC auxiliary contacts are provided; Additional contact can be provided upon request.
