ZVAThe series of non-disassembly calibration valves is a type ofSF6density relay andSF6a connection device for the gas chamber. After assembling this product, it allows electrical maintenance personnel to calibrate or replace theSF6gas density relay without power interruption. This product completely solves the disassembly problems during relay calibration, replacement, and gas replenishment, avoiding issues such as thread damage, sealing surface, and sealing ring damage caused by disassembling the density relay joints during regular calibration.SF6It can greatly reduce the probability of leakage, significantly improve the work efficiency of equipment calibration and maintenance, and ensureSF6the safe operation of electrical switches.
