Do not disassemble online verification test, strong air tightness, can be paired with various specifications at home and abroad switch interface, worry, safety!
summarize
SF6 density relay online calibration three-way valve device (WFS-A21-3I) is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, by operating the knob on the online detection valve, 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 "Twenty-five Key Requirements of the Energy Bureau 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 online calibration three-way valve device is mainly suitable for the power industry to achieve the requirements of online detection and calibration of non-disassembly density relays, improve the convenience of SF6 density relays without disassembly calibration and air replenishing, etc., and greatly improve the airtight guarantee of the body.
