Description
Technical field
The present invention relates to electric equipment maintenance assistant tool technical field, especially relate to SF when sulfur hexafluoride electrical equipment keeps in repair
6pneumatic inflation auxiliary device.
Background technique
For filling SF
6the electrical equipment such as circuit breaker, current transformer, when break down overhaul or device memory storing gas occur to reveal lower than nominal pressure, needs re-fill in air chamber or fill into SF
6gas, to guarantee the safe and stable operation of the insulating property that equipment reaches enough, support equipment.On-the-spot to when needing the equipment tonifying Qi of inflation or inflate, the normal mode of direct tonifying Qi that adopts is carried out, and namely steel cylinder is connected with electrical equipment inflation inlet, carries out tonifying Qi by pressure difference.But the method exists many problems, the sulfur hexafluoride gas in steel cylinder stores in liquid form, during inflation, and SF when liquid state transforms to gas
6rapid spatial expansion, and along with a large amount of heat absorptions, around steam is condensed into frost and is attached to the position such as body and reduction valve, the temperature of interior of steel bottle also sharply declines, steel cylinder delivery pressure is more and more lower, and the pressure in equipment increases along with the increase of charge, make pneumatic inflation speed slow, when reaching pressure balance very soon, gas when inflation stops in equipment does not often reach nominal pressure value, now, still retaining a large amount of sulphur hexafluorides in steel cylinder cannot continue to be filled with again, and charging efficiency reduces.In addition, owing to there is condensation in steel cylinder, pipeline, temperature in steel cylinder is caused to reduce, even form solidification, the post-decompression sulphur hexafluoride initial stage due to its larger flowing velocity, pressure influence, often with liquid and gaseous state and the form access arrangement deposited, in this gas replenishment process, we can only judge aeration quantity according to the pressure gauge data with temperature detection, and accurately can not estimate the actual amplitudes of sulphur hexafluoride, deviation is larger.Gas into devices stabilization time enough after, liquid sulphur hexafluoride is gasified totally, and the gas pressure in equipment increases, and even exceedes its safety pressure, all can bring the impact and damage of can not ignore on the density monitor on equipment and equipment itself.During site operation, the heavier mobile difficulty of steel cylinder itself is large, and often easily topples over because lacking fixing device, causes actual bodily harm, therefore steel cylinder is placed in device, portable mobile to operator, time saving and energy saving, and safety operation control.
Therefore, we consider to take suitable method to heat sulfur hexafluoride gas, and make sulphur hexafluoride access arrangement in a gaseous form, simultaneously by the lithium sulfur content understood and enter in electrical equipment of weighing, the loss that said process brings can be avoided, improve charging efficiency.
Meanwhile, giving in equipment tonifying Qi process, the sulphur hexafluoride in steel cylinder can not flow out completely, gasify, and has many sulphur hexafluorides still to remain in steel cylinder, can not fully be used.Therefore, a heating equipment can be designed, to sulphur hexafluoride heating, accelerate its gasification, evaporation rate, reduce residual quantity, increase operation rate.
