Respond to the national environmental protection policy and adapt to the new direction of industry development.

The transportation and inspection department of the power grid company responded to the actual problems of the SF6 gas cabinet in operation:

There are many manufacturers of SF6 gas cabinets, the quality is uneven, and there is a lack of detection means in the acceptance link, resulting in a large number of SF6 gas cabinets in transit leaking. SF6 gas leakage will cause the following effects:

Although SF6 gas is a good insulating medium for electrical equipment, its equivalent greenhouse effect is 23900 times that of carbon dioxide, and gas leakage or illegal emissions will have a great impact on the natural environment.

Although SF6 gas is non-toxic, its molecular structure is much larger than that of natural air, so it is difficult to disperse naturally in closed air, and leakage will pose a serious threat to personal safety.

The leakage of SF6 gas cabinet will cause the overall insulation level of the switch cabinet to decrease, and the gas pressure gauge will give an alarm, so it must be cut off for maintenance or replacement in time.

The load switch and grounding switch of SF6 gas cabinet are insulated by SF6 gas. Operating the load switch and grounding switch under insufficient gas pressure may cause personal safety and equipment explosion risks.
