Problems solved by technology

[0007] 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 gasify due to the low temperature of the gas cylinder, resulting in unsatisfactory refill

Example Embodiment

[0018] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0019] Such as figure 1 The special handling device for SF6 gas cylinders shown includes a fixed bracket 5, a base 3 and a transmission system. The transmission system is wrapped around the base 3, and the fixed bracket 5 is fixed above the base 3. The fixing bracket 5 is an L-shaped structure, made of carbon steel material, standard GB / T718-2005, the carbon steel pipe model is ZTG-40, the outer wall diameter of the carbon steel pipe is 40mm, and the wall thickness is 5mm; the upper and middle parts are installed with two diameters It is a 330mm ring-shaped hoop 6, and the fixed bracket 6 is connected to the base 3 through a rotating pin 9 and a hydraulic rod 10. The hydraulic rod 10 can lift up or lower the fixed bracket 5, and the fixed bracket 5 rotates through the rotating pin 9 to meet the action requirements of the hydraulic rod 10. The transmis...

Abstract

The invention relates to a carrying device specially for SF6 gas cylinders. The carrying device is characterized by comprising a fixed support, a base and a transmission system, wherein the transmission system is wound around the base; and the fixed support is fixed above the base. The carrying device is compact and exquisite in structure and flexible and convenient in movement. The carrying device is operated by one single person to facilitate carrying of the gas cylinders; the carrying device is capable of climbing slopes and going upstairs and downstairs up and down; and besides, the carrying device is convenient for carrying gas cylinders, simple and convenient in operation, capable of performing electric transportation, labor-saving and efficient. The carrying device is provided with a weighing device for displaying the weight of the SF6 gas cylinders and the gas in real time; the carrying device is also capable of heating the gas cylinder so as to improve the gas charging efficiency; the carrying device is reliable in working, free of quick-wear parts and low in fault rate; and the carrying device is energy-saving and environment-friendly as being capable of climbing up hundreds of steps by carrying the steel cylinders after being electrically charged at a time.

Description

technical field [0001] The invention relates to a special handling device for SF6 gas cylinders. Background technique [0002] Question 1: [0003] 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. [0004] Question 2: [0005] 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...
