Description

A high-efficiency gasification and collection device for sulfur hexafluoride gas

technical field

The utility model relates to the field of inflatable equipment for electrical instruments, in particular to a high-efficiency gasification and collection device for sulfur hexafluoride gas.

Background technique

At present, the "one-to-one" inflation method is still mainly used to inflate sulfur hexafluoride gas equipment, that is, one gas chamber is connected to one bottle of gas to inflate. However, the gas chambers of sulfur hexafluoride gas equipment are relatively large, and generally require multiple bottles or even more than ten bottles of gas. Taking a power supply bureau site as an example, a total of 60 bottles of gas are needed to complete the inflation of the largest interval gas chamber at this station. Calculated for 1 hour of gas inflation, the total time to complete the inflation at this interval is up to 60 hours, and the inflation efficiency is low, resulting in long-term power failure of the equipment and waste of manpower and material resources. In addition, the micro water volume inspection of the equipment using the traditional inflation method is generally 100-120PPm, and sometimes the micro water volume exceeds the standard. This is because the gas cylinder needs to be replaced frequently during the entire inflation process, which may easily cause moisture to enter the equipment, resulting in unqualified micro-water volume.

At present, the method of improving the inflation efficiency is mainly to increase the gas vaporization speed by heating the gas cylinder, thereby accelerating the inflation efficiency. But this type of method still cannot solve the problems of long total inflation time and excessive water content caused by "one-to-one" inflation.

The current problems are as follows: 1. The "one-to-one" inflation method is inefficient; 2. Frequent replacement of gas cylinders may easily cause excessive water content; 3. During the gas cylinder inflation process, due to the gasification of liquid sulfur hexafluoride The heat absorption rate is too fast, resulting in frosting of the gas cylinder, which eventually makes it difficult to vaporize the remaining liquid sulfur hexafluoride in the gas cylinder, and the gas utilization rate in the gas cylinder is low.

At the same time, when it is necessary to inflate multiple devices at the same time, it can also be connected to multiple devices through multiple inflation ports, so as to realize simultaneous inflation of multiple devices and improve the inflation efficiency.

Further, a handle is also included, and the handle is provided on the tank body, and the device can be moved conveniently by setting the handle.

Further, it also includes an air pressure detection gauge, the air pressure detection gauge is arranged on the tank body, and the air pressure detection gauge is used to detect the pressure of the gas in the device.

Further, the tank body is of copper or aluminum alloy structure, the device is more durable, avoids the occurrence of rust and air leakage caused by long-term use, and the tank body can withstand relatively large gas pressure.

Further, a sealing gasket is provided between the gas injection flange and the gas injection part. By setting the sealing gasket, the sealing between the gas injection flange and the gas injection part is better, preventing air leakage or air from entering the device. Inside.

Compared with the prior art, the beneficial effects are:

1. Realize simultaneous gasification and inflation of multiple bottles of sulfur hexafluoride gas to improve inflation efficiency;

2. Connect the gas cylinder at one time and then inflate it to avoid water entering during the bottle change process;

3. Multiple converging devices can be used in series to meet the inflation capacity requirements of air chambers of different sizes.
