产品详情/ Product details
SF6 Density Relay three-way Valve device (Winfoss-A21-3I)
No disassembly online verification test, strong air tightness, can be pairedVarious specifications at home and abroad switch interface, worry free, safe and efficient!
summarize
SF6 density relay three-way valve device (Winfoss-A21-3I) is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, through the operation of the on-line detection valve knob, to realize the valve and the equipment body gas path. Thus, the aeration, aeration and micro-water, decomposition, purity test of the cavity in the body of the equipment and the on-line calibration and replacement of SF6 density relay controller are realized. According to Article 13.1.6 of the "25 Key Requirements of the National Energy Administration on Preventing power Production Accidents" (National Energy Safety (2014) No. 161), the connection between the sulfur hexafluoride density relay and the switchgear body should meet the requirements of not disassembling the check density relay.
Apply
SF6 Density Relay three-way Valve device (Winfoss-A21-3I)It is mainly applicable to the electric power industry to realize the online detection and verification requirements of non-disassembly density relays, improve the convenience of non-disassembly calibration and air replenishment of SF6 density relays, and greatly improve the airtight guarantee of the body.
