Abstract
A kind of transformer breather, comprise silica gel tank, lubricating cup, be located at the flange at center, silica gel tank top, described silica gel tank is by glass tank body, what be bolted at glass tank body port is upper, bottom end cover, be connected to, stay bolt between bottom end cover and be arranged on tank body and upper, sealing ring between bottom end cover is formed, described bottom end cover base bleed pipe inserts in lubricating cup, its special character is: upper, bottom end cover is arranged respectively silica gel inlet and silica gel outlet, silica gel inlet and silica gel outlet install seal cover, it is external that described stay bolt is positioned at glass jar, described bottom end cover outer rim is provided with the dash edge to downward-extension, the height of described lubricating cup is 80mm-100mm.Easy to operate, original hermetically-sealed construction can not be destroyed; Solve because of stay bolt be positioned at tank body therebetween poor sealing cause leak gas problem; Prevent winter snow-broth from being flowed in lubricating cup along bottom end cover bottom surface by silica gel tank wall; Prevent from forming oil film because oil contacts with silicon particle and losing the gas effect that absorbs water.
Description
Technical field
The utility model relates to a kind of transformer breather.
Background technology
Transformer is as the capital equipment in electric power system, its safe and stable operation directly affects the reliability of power supply, respirator, as a part for transformer, is generally made up of silica gel tank, the lubricating cup being located at silica gel pot bottom center, the flange that is located at center, silica gel tank top.Described silicone tube be by glass tank body, be bolted glass tank body port upper and lower end cap, to be connected between upper and lower end cap and by tank body through stay bolt, be arranged on the sealing ring glass tank body and end cap and the sealing gasket be arranged between stay bolt and end cap is formed; Described upper end cover is provided with silica gel and injects outlet.There is following problem in the transformer breather of this structure: 1, injects outlet owing to being only provided with a silica gel, when silica gel deliquescence needs to change, first lubricating cup will be unloaded, again the flange bolt of silica gel tank top is dismantled, then silica gel tank is inverted, make silica gel inject outlet by silica gel to discharge, complex operation; 2, due in unloading process, open sealing ring, when again installing, affect sealing effectiveness, easily leak gas; 3, stay bolt passes by silica gel tank, the sealing gasket that the junction of itself and end cap is arranged, and seals bad herein, easily causes gas leakage.4, the Winter Snow water capacity easily flows in lubricating cup by silica gel tank wall along bottom end cover bottom surface, easily makes oil ga(u)ge bursting by freezing after freezing.5, the height of lubricating cup is 20mm-60mm, and in lubricating cup, oil easily sucks in glass tank body, forms oil film, make silica gel lose deliquescent effect at Silica Surface.
Summary of the invention
The utility model is the problems referred to above that will solve prior art existence, provides a kind of transformer breather.
Technical solution of the present utility model is:
A kind of transformer breather, comprise silica gel tank, be located at the lubricating cup at silica gel pot bottom center, be located at the flange at center, silica gel tank top, described silica gel tank is by glass tank body, what be bolted at glass tank body port is upper, bottom end cover, be connected to, stay bolt between bottom end cover and be arranged on tank body and upper, sealing ring between bottom end cover is formed, described bottom end cover base bleed pipe inserts in lubricating cup, its special character is: upper, bottom end cover is arranged respectively silica gel inlet and silica gel outlet, silica gel inlet and silica gel outlet install seal cover, it is external that described stay bolt is positioned at glass jar, described bottom end cover outer rim is provided with the dash edge to downward-extension, the height of described lubricating cup is 80mm-100mm.
The beneficial effects of the utility model are:
1, owing to setting up silica gel outlet, directly can open silica gel outlet when changing silica gel and discharge, easy to operate, original hermetically-sealed construction can not being destroyed, preventing because unloading lower flange impact sealing.
2, stay bolt is positioned at outside tank body, solve because of stay bolt be positioned at tank body therebetween poor sealing cause leak gas problem.
3, bottom end cover outer rim is provided with dash edge, and prevent winter snow-broth from being flowed in lubricating cup along bottom end cover bottom surface by silica gel tank wall, oil ga(u)ge can not bursting by freezing.
4, add the height of lubricating cup, during air-breathing, in lubricating cup, oil can not enter tank body, prevents from forming oil film because oil contacts with silicon particle and losing the gas effect that absorbs water.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: silica gel tank 1, lubricating cup 2, flange 3, stay bolt 4, upper end cover 5, bottom end cover 6, seal cover 7, sealing ring 8, base bleed pipe 9, seal cover 10, glass tank body 101, silica gel inlet 501, silica gel outlet 601, dash are along 602.
Embodiment
As shown in the figure, this transformer breather, the flange 3 comprising silica gel tank 1, be located at the lubricating cup 2 of silica gel tank 1 bottom centre, be located at silica gel tank 1 top center; Described silica gel tank 1 is that the sealing ring 8 be arranged between silica gel tank 1 and upper and lower end cap is formed by glass tank body 101, the upper and lower end cap 5,6 being connected to glass tank body 101 port by stay bolt 4; The base bleed pipe 9 of described silica gel tank 1 to insert in lubricating cup 2 and with lubricating cup 2 inner bottom surface distance 1cm-2cm, upper and lower end cap 5,6 arranges silica gel inlet 501 and silica gel outlet 601 respectively, silica gel inlet 501 and silica gel outlet 601 are provided with seal cover 10, described stay bolt 4 is positioned at outside silica gel tank 1, described bottom end cover 6 outer rim is provided with dash to downward-extension along 602, and the height of described lubricating cup 2 is 80mm-100mm.
Described bottom end cover 6 end face is plane, discharges for the ease of silicon particle, and bottom end cover 6 end face can be the inclined-plane tilted to silica gel outlet 601 direction.
Claims (1)
1. a transformer breather, comprise silica gel tank, be located at the lubricating cup at silica gel pot bottom center, be located at the flange at center, silica gel tank top, described silica gel tank is by glass tank body, what be bolted at glass tank body port is upper, bottom end cover, be connected to, stay bolt between bottom end cover and be arranged on tank body and upper, sealing ring between bottom end cover is formed, described bottom end cover base bleed pipe inserts in lubricating cup, it is characterized in that: upper, bottom end cover is arranged respectively silica gel inlet and silica gel outlet, silica gel inlet and silica gel outlet install seal cover, it is external that described stay bolt is positioned at glass jar, described bottom end cover outer rim is provided with the dash edge to downward-extension, the height of described lubricating cup is 80mm-100mm.
