Description
Technical field
The utility model relates to a kind of making-up air device, particularly a kind of portable sulphur hexafloride circuit breaker vacuum gas supplementary device.
Background technology
Along with the development of switching technique and the needs of Electric Power Network Planning; The SF 6 high-voltage switch application more and more widely, in the long-time running process of switch and since switch outdoor with variation of temperature; The pressure of sulphur hexafluoride is also in continuous variation in the switch; Test owing to sulphur hexafluoride inside the Pass will splitting every year carries out little water simultaneously, or owing to there is a spot of gas leak phenomenon in the equipment self reason, part switch sulphur hexafluoride pressure can be reduced to below the standard value; Just should split this moment to close and carry out tonifying Qi; Because sulfur hexafluoride gas is had relatively high expectations to water content in the switch, if water content high meeting precocity switch blow-out overlong time in the process of folding, thus the dynamic/static contact scaling loss of switch or the blast of arc control device caused.Therefore to the switch tonifying Qi time, should mend into qualified sulfur hexafluoride gas, and for a long time in the gas ducting that air is placed water content higher, do not satisfy and split the requirement of closing tonifying Qi, simple vacuum extractor can't satisfy the extraction to each pipeline vacuum.
Therefore, a kind of portable sulphur hexafloride circuit breaker vacuum gas supplementary device has overcome the difficult problem of prior art, has satisfied to split to close the needs that vacuumize when carrying out tonifying Qi.
Summary of the invention
The purpose of the utility model provides a kind of technological design sulphur hexafloride circuit breaker vacuum gas supplementary device reasonable, simple for production, easy to carry, reaches the purpose that guarantees the tonifying Qi quality
For realizing above-mentioned purpose, the utility model adopts following technical scheme to realize:
A kind of portable sulphur hexafloride circuit breaker vacuum gas supplementary device; Comprise valve I, tonifying Qi joint, gas-charging connection, valve II, motor switch, motor, handlebar, pressure vacuum gauge, pipeline I, valve III, valve IV, pipeline II, vacuum pump, tool box and wheel, described handlebar bottom is provided with the tool box, and the both sides, tool box are provided with wheel; The handlebar bottom is provided with motor; The motor surface is provided with motor switch, and motor is connected with vacuum pump, and vacuum pump is connected with pressure vacuum gauge through the pipeline II; The pipeline II is provided with valve III and valve IV; On the pipeline II between valve III and the valve IV, be provided with the pipeline I, the pipeline I is connected with gas-charging connection through the valve II, and gas-charging connection is connected with the tonifying Qi joint through the valve I.
Compared with prior art, the beneficial effect of the utility model is:
A kind of portable sulphur hexafloride circuit breaker vacuum gas supplementary device; Have that volume is little, cost is low, simple in structure, convenience operation; Be easy to carry simultaneously and mobile working, improved construction condition greatly, improved tonifying Qi efficient and quality; Can satisfy the tonifying Qi needs of different model sulphur hexafloride circuit breaker, guarantee the vacuum property of tonifying Qi pipeline.
