Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0028] A multifunctional SF6 steel cylinder inflation device, comprising a vehicle body 1, a power supply unit 2, a heating unit 3, a measuring scale 4 and a gas pipeline 5,

[0029] The vehicle body 1 includes wheels 11 mounted on the bottom of the vehicle body;

[0030] The front of the car body 1 is open, the other three sides are installed with a heating unit 3, and a power supply unit 2 and a temperature control module 72 are also installed on the back of the car body 1. The car body 1 is U-shaped; A fixing device is provided to prevent the SF6 cylinder 6 from shaking in the device and causing the loosening of each connection part; the fixing device is a strap;

[0031] The heating unit 3 converts the electrical energy provided by the power supply unit 2 into thermal energy;

[0032] A gas pipeline 5 is installed i...

Abstract

The invention discloses a multifunctional SF6 steel cylinder aerating apparatus. The apparatus comprises a vehicle body, a power supply unit, a heating unit, a weigher and a gas conveying pipeline. A segment from a pressure reducing valve to the pipeline of the apparatus is provided with the heating device, and the temperature can be set and automatically controlled, so SF6 (sulfur hexafluoride) entering the apparatus is in a gaseous state by arranging the enough long conveying pipeline forming an S-shaped appearance in the heating unit; the bottom of the vehicle body is provided with the weigher, so the SF6 gas in a steel cylinder can be accurately metered, or the aerated used SF6 gas is metered; the apparatus is designed to be a cart with universal wheels, so transportation and use are convenient; and the body of the cylinder is placed in a space with three sides formed by the heating unit, so the cylinder body heated by heat of the heating unit, and the flushing of SF6 in the steel cylinder to a device is full.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for the maintenance of electrical equipment, in particular to an auxiliary device for inflating SF6 steel cylinders during the maintenance of sulfur hexafluoride electrical equipment. Background technique [0002] For electrical equipment such as SF6 circuit breakers, current transformers, etc., in the event of overhaul or leakage of the stored gas in the equipment below the rated pressure, it is necessary to refill or replenish SF6 gas into the gas chamber to ensure that the equipment achieves sufficient insulation performance to ensure the safe and stable operation of the equipment. When inflating or inflating equipment that needs to be inflated on site, it is often carried out in a direct way, that is, the cylinder is connected to the inflatable port of the electrical equipment, and the air is supplemented through the pressure difference. However, there are many problems with this meth...
