Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.Obviously, described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
A kind of gas-filling cabinet high leakproofness pole is equipped with leading-out terminal 2 at the top of shell 1 as shown in Figure 1, including shell 1
With controller 13,1 bottom of shell is equipped with end of incoming cables 3, and vacuum interrupter 4 is equipped in shell 1, is equipped with silicon above vacuum interrupter 4
Rubber layer 5 is equipped with insulating cylinder 6 below vacuum interrupter 4, and 4 two sides of vacuum interrupter are perfused with epoxy resin 7, and 1 two sides of shell are set
There is sealing room 8, sealing 8 end of room is fixed with air pump 9, and air pump 9 is equipped with air bag 10, and sealing is equipped with briquetting 11, briquetting 11 in room 8
It is equipped with pressure sensor 12.
Pressure sensor 12 is set to one end opposite with air bag 10 on briquetting 11, and pressure sensor 12 and controller 13 are wireless
It communicates, air pump 9 and controller 13 wirelessly communicate, and it is arranged symmetrically to seal room 8 there are four setting for sealing room 8.
Silastic-layer 5, insulating cylinder 6 and epoxy resin 7 around vacuum interrupter 4 can carry out vacuum interrupter 4 close
Envelope, leading-out terminal 2 and end of incoming cables 3 are used for the wiring of vacuum interrupter 4.Vacuum interrupter 4 electric arc generate when, inside can generate
Very big heat, these heats can be transmitted to epoxy resin 7 of the surrounding for sealing, after cooling after a period of time,
Epoxy resin 7 can restore original temperature, but since a degree of shape will occur for the epoxy resin of " expanding with heat and contract with cold " 7
Become.
Electric arc generates initial stage, and 7 temperature of epoxy resin is higher, and the volume of epoxy resin 7 will increase at this time, and push briquetting 11
Air bag 10 is pressed to, pressure sensor 12 is able to detect the pressure between briquetting 11 and air bag 10, and by wireless communication by data
It is sent to controller 13, control air pump 9 is evacuated controller 13 by wireless communication again, so that 10 volume of air bag reduces, avoids ring
Oxygen resin 7 causes to damage with vacuum interrupter 4 due to mutual extrusion.
After electric arc generates, epoxy resin 7 can restore original temperature through cooling after a period of time, at this time epoxy resin 7
Volume will reduce, and the pressure between briquetting 11 and air bag 10 reduces, and controller 13 controls air pump 9 and inflates into air bag 10, so that
Briquetting 11 presses to epoxy resin 7, avoids forming air layer due to not being bonded between epoxy resin 7 and vacuum interrupter 4, effectively
Improve the leakproofness before and after generating electric arc in vacuum interrupter 4 in pole.
A kind of gas-filling cabinet provided by the present invention is provided with silicon rubber with high leakproofness pole around vacuum interrupter
Glue-line, insulating cylinder and epoxy resin are sealed, when generating electric arc in vacuum interrupter and issue amount of heat, epoxy resin
