Description

Special handling device for SF6 gas cylinder

technical field

The utility model relates to a special handling device for SF6 gas cylinders. the

Question 1:

At present, Zibo Power Supply Company has jurisdiction over 93 substations, including 36 GIS substations. Most of the 36 GIS substations have a second-floor GIS equipment area, and all circuit breakers of 100KV and above substations are SF6 circuit breakers. Due to the large number of SF6 equipment and long-term operation, there is often the possibility of air leakage, which requires regular air replenishment. When invigorating, it is necessary to frequently carry the cylinder up and down the stairs. the

Question 2:

The weight of the SF6 gas cylinder itself is 50KG, and the net weight of a bottle of fresh gas is 50KG. After being filled with new gas, the total weight of the SF6 gas cylinder is 100KG. In addition, the gas cylinder is cylindrical and there is no handle around it, so it is necessary to carry the gas cylinder. It needs many people to work at the same time, which is time-consuming and labor-intensive, and because the stairs are narrow, there is an unsafe factor that the gas cylinder will roll and hurt people during the transportation process. the

Question 3:

When SF6 gas is recharged from the gas cylinder to the SF6 electrical switch, the pressure in the gas cylinder is greater than the pressure in the electrical switch, and the liquid SF6 in the gas cylinder will be converted into gaseous SF6 and output to the electrical switch when the pressure is reduced, so There will be a physical phenomenon of heat absorption during the conversion process, and the SF6 gas cylinder will often fail to vaporize the SF6 gas due to the low temperature of the cylinder, and the refill efficiency is not ideal. Especially in cold weather environment, because the temperature of SF6 in the gas cylinder will drop sharply, frost will appear around the gas cylinder, prolonging the inflation time, and the risk of moisture in the external gas entering the equipment gas chamber at the inflation interface will increase. When the temperature drops, SF6 will change from gaseous state to liquid or even solid state, and the gas supply can only be continued after the temperature rises, and the entire gas supply process will take a long time. the
