JHGC-HQ series SF6 mixed gas valve filling device
For air distribution, air replenishment and filling of environmentally friendly insulated electrical equipment
At the same time, it has the function of gas replenishment. The device can automatically calculate the gas replenishment ratio parameters according to the gas parameters in the mixed gas chamber, automatically adjust the gas distribution ratio, and ensure the accuracy of the mixing ratio in the mixed gas electrical equipment
