Description
Technical field
The utility model relates to a kind of respirator for transformer more particularly to a kind of double filter ventilators of transformer.
Background technique
After main transformer of transformer substation changes colour because of the respirator interior silica gel moisture absorption, need to re-replace new silica gel.Usual
In the case where, it should be by removing respirator and breathing the screw on pipe flange, to complete the integral demounting to respirator, to reach
More renew the purpose of silica gel.In disassembly, need to back out on the screw on transformer flange, it is time-consuming and laborious, while increasing work
The work difficulty of industry personnel.More importantly existing respirator is after removal, due to not preventing main fransformer oil effectively
The barrier of respiratory siphon and air is rested the head on, it can be during replacing respirator silica gel, main transformer conservator passes through respiratory siphon and air
It directly contacts, to lose the real effect of respirator.Especially in summer wet weather, the fouling product of moisture and air,
All very likely enter inside main transformer conservator, causes the rapid degradation of main fransformer oil.In addition, when respirator lower part breathes
After hole plug, negative pressure can occur in respirator interior, if could not conscientiously check discovery before staff dismantles respirator, tear open
When unloading respirator, Buchholz relay can be impacted, the malfunction of Buchholz relay is caused because air rapidly enters respiratory siphon,
Such example be also it is aobvious have it is existing.
Summary of the invention
The utility model is directed to above-mentioned problems of the prior art, provides a kind of transformer double filter ventilators,
It avoids during replacing respirator silica gel, occurs because causing main fransformer oil directly to connect with air after respirator disassembly
The problem of touching.
The technical solution of the utility model is as follows:
Silica gel, the bottom of silica gel tank is arranged in transformer double filter ventilators, including silica gel tank and lubricating cup, the inside of silica gel tank
Portion connects lubricating cup;The inside of the silica gel tank is equipped with self-filtering tank, and self-filtering tank is filled with silica gel, self-filtering tank
Top is connected to one end of connecting tube, and the other end of connecting tube stretches out silica gel tank and is connected to the pedestal of mounting flange, mounting flange
The top of pedestal and silica gel tank be detachably connected with, top and the transformer flange of mounting flange are fastenedly connected.
The mounting flange matches with transformer flange screw pitch.
The top of the mounting flange uses back taper open type through-hole, and the bottom end of through-hole is connected to connecting tube, through-hole
Top is connected to transformer respiratory siphon.
The pedestal of the mounting flange is cylinder, and the inner wall of the inner hollow of cylindrical base, cylindrical base is set
There is internal screw thread, internal screw thread matches with silica gel upper end external screw thread, and the pedestal and silica gel tank of mounting flange are twisted solid by screw thread.
At the threaded recess of the pedestal internal screw thread of the mounting flange, it is equipped with venthole.
The connecting tube is identical as transformer breathing pipe diameter.
The self-filtering tank is transparent tank body, and the upper end of tank body is connect with connecting tube using solid mode is twisted, tank body
Bottom end is using breathing web frame.
Bore is greater than the tank diameter of self-filtering tank in the tank body upper end of the silica gel tank.
The utility model has the advantages of as follows:
1. the utility model is separated by turning silica gel tank, by the internal screw thread of mounting flange with the external screw thread of silica gel tank, behaviour
It is simple, convenient to make.
2. the utility model can limit air in silica gel by way of in the punching of the internal screw thread recess of mounting flange
Inflow velocity in the case of tank internal negative pressure slows down the impact to transformer Buchholz relay, so as to avoid Buchholz relay
Malfunction.
3. the utility model, when replacing silica gel tank silica gel, is guaranteed after dismantling silica gel tank using self-filtering tank is installed additional, interior
Portion's filtering tank is still connected to transformer respiratory siphon, was continued to complete the effect of air filtering, and not will cause air and transformer oil
Direct contact.The effect of double filterings is also played simultaneously.

Specific embodiment
The utility model is described as follows referring to attached drawing by specific embodiment.
Embodiment
As shown, silicon is arranged in transformer double filter ventilators, including silica gel tank 5 and lubricating cup 8, the inside of silica gel tank 5
The bottom of glue 7, silica gel tank 5 connects lubricating cup 8;The inside of the silica gel tank 5 is equipped with self-filtering tank 6, and self-filtering tank 6 is filled
There is silica gel, the top of self-filtering tank 6 is connected to one end of connecting tube 4, and the other end of connecting tube 4 stretches out silica gel tank and fixation
The pedestal connection of orchid 2, the connecting tube 4 are identical as transformer breathing pipe diameter.The pedestal of mounting flange 2 and silica gel tank 5
Top is detachably connected with using screw thread, and the fixing threaded hole 3 of mounting flange 2 matches with the screw hole screw pitch of transformer flange 1, fixed
The top of flange is connect with transformer flange by screw threads for fastening.
The top of the mounting flange uses back taper open type through-hole 11, and the bottom end of through-hole is connected to connecting tube 4, through-hole
Top be connected to transformer respiratory siphon.Formula through-hole is open upwards using back taper, in favor of connecting with transformer mounting flange
Afterwards, airway unobstructed.
The pedestal 10 of the mounting flange is cylinder, the inner hollow of cylindrical base, the inner wall of cylindrical base
Equipped with internal screw thread, internal screw thread matches with silica gel upper end external screw thread, and the pedestal and silica gel tank of mounting flange are twisted solid by screw thread.
At each threaded recess of the pedestal internal screw thread of the mounting flange, it is equipped with venthole 9.
Transparent tank body is made using glass material in the self-filtering tank 6, convenient for observing the suction of self-filtering tank silica gel
Damp situation.The upper end of tank body is twisted solid mode using screw thread with connecting tube and is connect, and using breathing web frame, guaranteeing should for the bottom end of tank body
Self-filtering tank it is unimpeded.
Bore is greater than the tank diameter of self-filtering tank in the tank body upper end of the silica gel tank, when mounting flange internal screw thread
After separating with silica gel tank external screw thread, self-filtering tank can pass through the bore of silica gel tank, after completing the disassembly of silica gel tank, internal-internal
Filtering tank is still connected to transformer respiratory siphon, using this double filter types, avoids the direct of main fransformer oil and air
Contact.
For the homework burden for mitigating staff, the utility model is used on the basis of transformer flange itself, design one
A matched mounting flange, haves no need to change the structure other than transformer respiratory siphon, and mounting flange passes through screw and transformer method
Orchid twists solid.When designing mounting flange, using screw thread twist it is solid by the way of connect with silica gel tank, can thus reduce operation
It is cumbersome.Meanwhile to prevent during replacing silica gel, there may be negative pressure for respirator interior, easily cause Buchholz relay
Malfunction, in each internal screw thread recess of mounting flange, by the way of getting through stomata, when dismantling silica gel tank, if
Occur having negative pressure inside silica gel tank, when turning disassembly silica gel tank, can gradually pass air through self-filtering tank by venthole
Into transformer respiratory siphon, air-flow is stepped into, and limit air flows rapidly into transformer, it will be able to avoid transformer gas
The malfunction of relay.The utility model essentially consists in disassembly, it is only necessary to turn once, by the internal screw thread and silicon of mounting flange
Disassembly can be completed in the external screw thread disengaging of glue tank.
