Description

A kind of sulfur hexafluoride gas high-efficiency gasification aggregating apparatus
Technical field
The present invention relates to the charger field of electric apparatus, more particularly, to a kind of sulfur hexafluoride gas efficient air Change aggregating apparatus.
Background technology
At present, the main airing form for still using " single pair list " is inflated to sulfur hexafluoride gas equipment, i.e. an air chamber connects One bottle of gas is inflated.But sulfur hexafluoride gas equipment air chamber is all bigger, more bottles even more than ten bottles of gas is generally required, By taking certain power supply administration's website as an example, station largest interval air chamber is completed once to inflate to need 60 bottles of gas altogether, inflate 1 hour by every bottle of gas based on Calculate, complete the total time-consuming of interval inflation up to 60 hours, charging efficiency is low, causes equipment to have a power failure for a long time and manpower and materials Waste.In addition, being generally 100-120PPm using traditional micro- water inspection of airing form equipment, also occur micro- water sometimes and surpass Mark problem.This is due to need frequently to change gas cylinder in whole gas replenishment process is completed, and easily causes moisture and enters equipment, causes micro- The unqualified problem of water.
The method for improving charging efficiency is taken mainly to improve gas vaporization speed by being heated to gas cylinder at present, So as to accelerate the efficiency of inflation.But such method still can not solve, and the inflation total time that " single pair list " aeration zone comes is long, micro- water Measure the problem of exceeded.
The problem of presently, there are have it is following some：First, " single pair list " airing form charging efficiency is low；2nd, frequently change It is exceeded that gas cylinder easily causes micro- water；3rd, during inflating gas cylinder, due to the too fast heat absorption of liquid sulfur hexafluoride gasification rate, make Into gas cylinder frosting, the remaining liquid sulfur hexafluoride for ultimately resulting in gas cylinder is difficult to gasify, and gas effciency is low in gas cylinder.
The content of the invention
The present invention is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of sulfur hexafluoride gas efficient air Change aggregating apparatus, charging efficiency is high, micro- water is up to standard, and gas effciency is high.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of sulfur hexafluoride gas high-efficiency gasification converges Acquisition means, including tank body, several gas injection flanges, several inflation inlets, exhaust outlet and stop valve, described gas injection flange are located at On tank body, described inflation inlet is connected with exhaust outlet by stop valve with tank body.
When needing to be inflated equipment, multiple gas cylinders equipped with sulfur hexafluoride gas are passed through into tracheae and gas injection flange Connection, sulfur hexafluoride gas is injected into tank body, opens the stop valve of exhaust outlet, is closed after the air in device is completely exhausted out The stop valve of exhaust outlet is closed, inflation inlet and equipment are connected by tracheae, sulfur hexafluoride gas is filled with equipment.
Further, described tank body includes charging portion and gas injection section, and described charging portion passes through detachable with gas injection section Valve connects, and on charging portion, several gas injection flanges work as inflation on gas injection section for described inflation inlet and exhaust outlet Sulfur hexafluoride gas amount needed for equipment is few（As 1 bottle of gas is enough）When, can by removable valve goalkeeper charging portion and Gas injection section is taken apart, and sulfur hexafluoride gas cylinder directly is accessed into charging portion by dismountable valve；When equipment needs are substantial amounts of lithium Sulphur gas（Such as need more bottles of gases）When, the gas injection flange on multiple sulfur hexafluoride gas cylinders access gas injection section can thus be kept away One bottle of sulfur hexafluoride gas deficiency is exempted from, it is necessary to change the problem of moisture enters so as to cause micro- water exceeded during gas cylinder. It simultaneously when need to be inflated multiple equipment simultaneously, can be also connected, realized with multiple equipment by multiple inflation inlets Multiple equipment is inflated simultaneously, improves charging efficiency.
Further, in addition to handle, described handle is on tank body, by setting handle to be moved easily this dress Put.
Further, in addition to air pressure detection table, described air pressure detection table are located on tank body, and air pressure detection table is used to examine Survey the pressure of gas in device.
Further, described tank body is copper or aluminium alloy structure, and device is more durable, and avoiding long-term use causes to give birth to The situation of rust gas leakage occurs, and tank body can bear larger gas pressure.
Further, gasket seal is provided between described gas injection flange and gas injection section, by setting gasket seal to make note Better tightness between gas flange and gas injection section, prevent gas leakage or air from entering in device.
Compared with prior art, beneficial effect is：
1st, more bottles of sulfur hexafluoride gas are realized while inflation of gasifying, improves charging efficiency；
2nd, disposably connect gas cylinder to be inflated again, avoid moisture during changing bottle from entering；
3rd, more aggregating apparatus can be used in series, and meet different size of chamber inflated capacity requirement.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art, Some known features and its explanation may be omitted and will be understood by accompanying drawing.Being given for example only property of position relationship described in accompanying drawing Explanation, it is impossible to be interpreted as the limitation to this patent.
As shown in figure 1, a kind of sulfur hexafluoride gas high-efficiency gasification aggregating apparatus, its tank body is by 2 groups of charging portion 1 and gas injection section Into charging portion 1 is connected with gas injection section 2 by dismountable valve, and several gas injection flanges 21, gas injection are provided with gas injection section 2 Gasket seal is provided between flange 21 and gas injection section 2, device sealing can be made better, prevents air from entering device or hexafluoro Change sulphur gas leakage.Exhaust outlet 12 and several inflation inlets 13 are provided with charging portion 1, inflation inlet 13 and exhaust outlet 12 pass through Stop valve 11 is connected with charging portion 1.Air pressure detection table 14 is provided with charging portion 1, can be examined in real time by air pressure detection table 14 The air pressure surveyed in device.
Wherein, handle 3 is equipped with gas injection section 2 and charging portion 1, easily can be lifted the present apparatus by handle 3, Convenience in transport moves the present apparatus.
