Abstract

The invention relates to a transformer respirator, which comprises a silica gel tank, an oil cup and a flange, wherein the flange is arranged in the center of the top of the silica gel tank, the silica gel tank consists of a glass tank body, an upper end cover, a lower end cover, long screw bolts and sealing rings, the upper end cover and the lower end cover are connected onto an end opening of the glass tank body through screw bolts, the long screw bolts are connected between the upper end cover and the lower end cover, the sealing rings are arranged between the tank body and the upper and lower end covers, and an exhaust pipe arranged at the bottom of the lower end cover is inserted in the oil cup. The transformer respirator is characterized in that a silica gel filling opening and a silica gel discharging opening are respectively formed in the upper end cover and the lower end cover, sealing covers are arranged on the silica gel filling opening and the silica gel discharging opening, the long screw bolts are positioned outside the glass tank body, the outer edge of the lower end cover is provided with a downwards extending water blocking edge, and the height of the oil cup is 80mm to 100mm. The operation is convenient, and the original sealing structure cannot be destroyed; the problem of air leakage caused by poor sealing between the long screw bolts and the tank body since the long screw bolts are positioned in the tank body is solved; snow water in winter is prevented from flowing into the oil cup from the outer wall of the silica gel tank along the bottom surface of the lower end cover; the loss of aqueous vapor absorption effect due to oil film forming through the contact of oil and silica gel particles is prevented.

Description

Transformer breather

Technical field

The present invention 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 present invention is the problems referred to above that will solve prior art existence, provides a kind of transformer breather.

Technical solution of the present invention 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 invention has the beneficial effects as follows:

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 invention.

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.
