Background technique

In the power industry, power supply companies often need to fill sulfur hexafluoride steel cylinders for sulfur hexafluoride high-voltage equipment. When the liquid sulfur hexafluoride in the steel cylinder is filled into the high-voltage equipment, sulfur hexafluoride will change from liquid to gas, absorbing a lot of heat , If there is no external heat source to continuously add heat to the steel cylinder, most of the sulfur hexafluoride remaining in the steel cylinder will not be discharged, and the electric power safety requirement cannot use an open flame to supplement the heat source. In the past, the heating device for heating sulfur hexafluoride steel cylinders used the structure of heating tubes and box-type brackets to heat the cylinder body. From 16.0cm to 24.5cm, the previous heating devices cannot be flexibly used on steel cylinders of various specifications, and the versatility is poor. And as the common knowledge of those skilled in the art, sulfur hexafluoride steel cylinders are not suitable for high temperature treatment, and the heating temperature needs to be kept within a suitable temperature range. However, due to the uneven heating area and poor heating effect of the previous heating devices, it is not possible to heat the steel cylinder. If the temperature is kept within the appropriate range, the temperature may exceed the rated value; moreover, when sulfur hexafluoride is charged into high-pressure equipment, the valve port of the steel cylinder will gradually form frost and dew due to heat absorption, which is very easy to cause The micro-water content of sulfur hexafluoride charged into high-pressure equipment is too high, and it is the consensus of the power industry that too high micro-water content will cause many serious consequences. However, all previous heating devices have not considered the treatment measures for the valve port. In order to meet the actual needs of the actual substation overhaul of power supply enterprises. the
