Description
Affiliated technical field:
The utility model relates to a kind of electric power system supplementary equipment, particularly high pressure SF6 equipment quick air-inflating apparatus.
Background technique:
SF6 (sulphur hexafluoride) is a kind of fabulous gaseous dielectric of high-tension apparatus that is applied to, and it has been widely used in electrical equipments such as circuit breaker, GIS (insulated metal sealing switch equipment), transformer.Combined electric equipment such as GIS need a large amount of SF6 gas, and the generally all assemblings at the scene of these equipment, on-the-spot inflation.Main equipment fills the problem that SF6 gas is a comparison difficulty at present.Subject matter has, and the first, aeration speed is too slow, incurs loss through delay built-up time, has extended the construction period greatly; The second, a large amount of SF6 gases of residue in the SF6 steel cylinder, SF6 gas price costliness causes serious waste, has increased power cost greatly.In order to reduce inflationtime, reduce remaining gas flow in the steel cylinder, people adopt three kinds of following methods: 1. in inflation, directly the steel cylinder bottom is heated with inflammable matters such as firewoods, but SF6 steel cylinder bottom can be burnt black, be unfavorable for the recovery of producer to steel cylinder, and the heat that firewood combustion produces is big and inhomogeneous, and temperature is extremely low in the steel cylinder, because the part acutely is heated, cause the blast of SF6 steel cylinder probably, dangerous.2. in inflation, steel cylinder is put on the powerful heating system.This method also can only provide part vaporization required heat because the steel cylinder hot area is little, and also is the blast that local heating still may cause steel cylinder.3. in inflation, with the flame baking steel cylinder surface of blowtorch, comparison difficulty but execute-in-place gets up, and the flame of blowtorch can not the balance steel cylinder in the heat that needs of SF6 vaporization.In the time of in the winter time, inflation in this way, freezing will appear in the steel cylinder bottom about 8 minutes, just stops inflation about 10 minutes substantially, and this method does not still have effectively to solve the many difficult problems of residual gas in inflationtime length and the steel cylinder.
The model utility content:
The utility model purpose provides a kind of high pressure SF6 equipment quick air-inflating apparatus, reduces inflationtime, reduces remaining gas flow in the steel cylinder, and is safe and reliable, solves the problems referred to above that background technique exists.
The technical solution of the utility model is: high pressure SF6 equipment quick air-inflating apparatus comprises water container, electric heating apparatus, power supply, SF6 steel cylinder, and the SF6 steel cylinder is arranged in the water container, and water heater is placed in the SF6 steel cylinder water on every side, and power supply is connected with water heater.
Can the SF6 steel cylinder be sling by crane gear during use, the SF6 steel cylinder is suspended in the water container, and does not touch with the bottom connection of water container the bottom of SF6 steel cylinder.Also can support be set in the bottom of water container, the height of support is lower than the water surface, and the SF6 steel cylinder is placed on the support.
The utility model also is provided with the insulation rubber cushion, and water container is placed on the insulation rubber cushion.
Adopt the utility model, the SF6 steel cylinder is arranged in the water container, the temperature of control inner bucket water; The staff wants the tape insulation rubber gloves, and forbidding directly catches touches SF6 steel cylinder and water heater.If discovery steel cylinder bottom freezes, when the coolant-temperature gage in the bucket is not high, can increase water heater, increase heat.If the temperature of water is too high in the discovery bucket, in time reduce water heater, to reduce heat in the bucket.Reduce the temperature of water, aeration speed can slow down.Improve the temperature of water and can accelerate aeration speed.Because the temperature of gas replenishment process inner bucket water is controlled between 30-40 degree centigrade, the temperature of water is very low, and well below the fluidizing point of water, so the steam output of inner bucket water is very little, can influence the humidity of whole inflation environment hardly.If the inflation environment is airtight and little, can open ventilation plant, reduce the humidity of air.After inflation is finished to GIS combined electric equipment in this way, need in the quiescence time of regulation, place, each independent air chamber to the GIS combined electric carries out the detection of SF6 gas micro-water content, SF6 gas micro-water content is less than state specified standards (the equipment SF6 micro-water content before putting into operation≤150ul/L), the SF6 micro-water content basically identical that records with common inflation.That is to say that water can't influence the micro-water content of the SF6 gas in the equipment of charging into for the heating of SF6 steel cylinder.
The beneficial effects of the utility model are: are not subjected to the influence of seasonal temperature, are not subjected to the restriction of geographical environment, and can widespread usage; Inflation method is simple to operate, and equipment needed thereby realizes that easily cost is low; Solved a long difficult problem such as GIS (insulated metal sealing switch equipment) large-scale SF6 electrical equipment inflationtime, and SF6 gas fully can be used, significantly reduce remaining SF6 gas in the steel cylinder, greatly reduced the cost of electrical equipment, had very big social value and economic value.
