SF6 density relay three-way valve connector（Winfoss-A21-3I）

Non disassembly online verification and testing, strong airtightness, can be pairedVarious specifications of switch interfaces at home and abroad, worry free, safe and efficient!

overview

SF6 density relay three-way valve connector（Winfoss-A21-3I）It is mainly used in high-voltage equipment in the power industry that uses SF6 gas as the arc extinguishing medium. By operating the knob on the online detection valve, the valve and the equipment body gas path can be connected or disconnected, thereby realizing the inflation, replenishment, micro water, decomposition products, purity testing of the equipment body cavity, as well as online verification and replacement of SF6 density relay controllers.

According to the "25 Key Requirements of the National Energy Administration on Preventing Power Production Accidents" (National Energy Safety)2014[]161 Document No.)13.1.6Regulation: The connection method between the sulfur hexafluoride density relay and the switchgear body should meet the requirement of not disassembling and verifying the density relay

application

SF6 density relay three-way valve connectorIt is mainly suitable for the power industry to achieve the requirement of online detection and verification of non dismantling density relays, which improves the convenience of non dismantling verification and gas replenishment of SF6 density relays, and greatly enhances the airtightness guarantee of the body.
