SF6 density relay three-way valve assembly joint

SF6 Density Relay Three-Way Valve Assembly Connector (Winfoss-A21-3I)

No disassembly for online verification and testing, strong air tightness, and can be paired with various specifications of switch interfaces at home and abroad!

Overview

SF6 density relay three-way valve assembly joint (Winfoss-A21-3I) 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 can be connected In order to realize the on-line verification and replacement of the air-filling, air-supplying and micro-water, decomposition products, purity test of the inner cavity of the equipment body, and SF6 density relay controller.

According to Article 13.1.6 of the Twenty-Five Key Requirements of the National Energy Administration on Preventing Electric Power Production Accidents (Guo Neng Security [2014] No. 161): the connection between the sulfur hexafluoride density relay and the switchgear body The method should meet the requirement of not disassembling the verification density relay.

Applications

The SF6 density relay three-way valve assembly joint is mainly suitable for the power industry to meet the requirements of on-line inspection and verification of the density relay without disassembly, which improves the convenience of the SF6 density relay without disassembly, verification and air supply, and thus greatly improves the airtightness of the body. Assurance.
