Embodiment Construction

[0012] like figure 1 As shown, a sulfur hexafluoride gas cylinder automatic heating and filling device includes a trolley, a gas cylinder 2, a coil heater 3, and a control cabinet 4; Tighten the bolts and nuts 5 to fix several coil heaters 3, the inner diameter of the coil heaters 3 is slightly larger than the outer diameter of the gas cylinder 2; the gas cylinder 2 is inserted into the coil heater 3 and fixed on the trolley Above the platform 6, the control cabinet 4 is installed under the trolley platform 6 and close to one end of the trolley handle 7.

[0013] Instructions:

[0014] When the automatic heating and filling device for sulfur hexafluoride gas cylinders of the present invention is in use, the gas cylinder 2 is inserted into the coil heater 3, the trolley is pushed or pulled to the operating place, the power is turned on, and the temperature upper limit is selected on the control panel. Press the heating button. When the temperature reaches the required tempera...

Abstract

The invention belongs to the technical field of breakers and combined electrical apparatuses for filling sulfur hexafluoride gas and relates to an automatic heating and aerating device of a sulfur hexafluoride cylinder, which comprises a trolley, the cylinder, a circle-type heater and a control cabinet. The cylinder is inserted into the circle-type heater and fixed with a trolley platform, the heating temperature is selected on an operation panel of the control cabinet, a cylinder body is kept in a certain temperature, and the sulfur hexafluoride gas in the cylinder can be discharged to the maximum extent, and therefore the automatic heating and aerating device of the sulfur hexafluoride cylinder improves gas use ratio, shortens aerating time, saves aerating cost and is safe and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of a circuit breaker and a combined electrical appliance for charging sulfur hexafluoride gas, and in particular relates to an automatic heating and charging device for a sulfur hexafluoride gas bottle. Background technique [0002] At present, the replacement of power equipment is becoming more and more frequent, and the traditional oil-filled equipment is basically replaced by gas-filled SF6 circuit breakers and combined electrical appliances. 6 Circuit breakers and combined electrical appliances are widely used in power transmission and transformation equipment due to their good safety performance and technical performance; however, when installing and daily maintaining these equipment, it is often necessary to carry out necessary air charging and replenishment. [0003] When the liquid SF in the cylinder 6 When the gas is filled into the equipment, the liquid state becomes gaseous state, which absorbs a...
