Description
Technical field
The utility model relates to the liquid apparatus for changing of a kind of SF6 gas, belongs to technical field of electric equipment.
Background technique
In recent years, along with the raising with technical equipment that develops rapidly of China's power industry, SF6 electrical equipment puts into operation in a large number, SF6 gas is with the insulation of its excellence and arc extinction performance, be used widely in electric power system, almost become the unique insulation and arc-extinguishing medium that use in middle pressure, high pressure and ultra-high pressure switch.At present, in China 63 ~ 750KV electric power system, the application of SF6 gas insulation breaker and SF6 gas insulated transformer substation (GIS) has been quite extensive, therefore becomes more and more important to the day-to-day supervision work of SF6 electrical equipment.
Because SF6 equipment is various and through long-play, often there is may occurring of gas leakage, this just needs regularly to carry out tonifying Qi.Following problem is there is: 1, SF6 gas cylinder must be adopted during tonifying Qi during tonifying Qi operation, a steel cylinder nearly weighs 105kg greatly, and during current 110kV electric substation GIS device exemplary configurations, generally be arranged on 2nd floors and above floor, fill at every turn, tonifying Qi time, the carrying of SF6 gas cylinder is just cumbersome upstairs, especially can waste a lot of time and manpower when rushing to repair process.2, the specification of SF6 charger (circuit breaker, GIS etc.) is not quite similar, and on-the-spot tonifying Qi demand is also distinguish to some extent.Working experience according to reality is summed up known: the tonifying Qi work gas consumption of 70% is only at below 15kg.But all need to carry the steel cylinder of the 105kg that weighs during each on-the-spot tonifying Qi and need crane to coordinate, waste more material resources, add tonifying Qi cost.3, carry out when ambient temperature is lower filling, tonifying Qi, heater heating area cannot cover whole steel cylinder, SF6 gas not easily gasifies, steel cylinder meeting heavy ice, affect aeration speed 4, for adapting to the O&M of general overhaul in the future framework for intergration reform orientation, the possibility that person on duty carries out filling tonifying Qi increases greatly, and female person on duty is generally reflected and removed motionless gas cylinder.
For the problem of encountering in real work, bottle tonifying Qi is used effectively to overcome the above problems.But the extensive steel cylinder of small capacity that uses faces many objective factors:
(1) investigate domestic and international market to find: the about 8%--10% on the low side of the cyclinder gas every kilogram average price of 40L capacity comparatively 10L, 15L capacity.When purchasing in a large number, difference in selling prices can be all the more obvious;
(2) need when new equipment is delivered for use to fill a large amount of SF6 gas, buy jumbo cylinder filling gas and can reduce purchase steel cylinder radix, save purchase cost; If administrative electric substation all changes into buy small bottle packing gas, huge expenditure cost can be increased and bring the comparatively large resource waste filling rear more small capacity gas cylinder and leave unused caused;
(3), when simple large steel cylinder is filling to small steel cylinder, in Large Copacity gas cylinder, liquid state cannot fast to bottleneck flowing, and what fill mostly is gaseous state; Because small capacity steel cylinder volume is less, when gaseous state, a small amount of gas can reach pressure balance, and filling weight is few, and pressure is large; Utilize common recovery vehicle to carry out filling, not easily ensure gaseous mass; Utilization is carried out filling meeting without oil recovery device and is brought equipment volume comparatively large, the problems such as equipment price is higher.Meanwhile, both at home and abroad without the small combined exchangeable device of specialty.
Existing steel cylinder heating equipment structural feature is: 1, investigate market product and find, all amateur exchangeable device of existing exchangeable device, but utilize the recovery compression function of SF6 recovery vehicle to change the outfit.Recovery vehicle volume is comparatively large, and mobile inconvenience, uses comparatively loaded down with trivial details; 2, existing recovery vehicle mostly is hand push button control, controls comparatively random, cannot precisely control change the outfit weight and pressure, there is certain potential safety hazard; 3, the non-professional exchangeable device of recovery vehicle, the efficiency that changes the outfit is lower.
