SF6Anti misoperation valve control three-way connector（Winfoss-A21-3D）

Non disassembly online verification and detection, anti misoperation mechanical lock, can be pairedVarious specifications of switch interfaces at home and abroad, worry free, safe and reliable!

Overview

SF6Anti misoperation valve control three-way connector（Winfoss-A21-3D）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 and replenishment of the equipment body, as well as the online calibration and replacement of SF6 density relay controllers. This product is equipped with an anti misoperation mechanical lock to prevent the equipment from being operated during operation, ensuring the safety and reliability of the equipment during operation.

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.
