Technical field
The utility model belongs to technical field of electrical equipment, and in particular to a kind of transformer oil with piston respirator
Pillow.
Background technology
Oil-filled transformer has the characteristics that good heat dissipation, loss is low, capacity is big, price is low, therefore electric online operation at present
Power transformer it is most of be oil-filled transformer.The characteristics of oil-filled transformer maximum is exactly to need to soak unshakable in one's determination with winding
Steep in insulator oil, but in order to prevent fuel tank interior insulation body oil by air Quick Oxidation, while ensure to meet heat expansion again
The Volume Changes of insulator oil during shrinkage, therefore design conservator is also needed in addition to oil tank of transformer in field transformer.Work as transformation
When the volume of device oil expands or reduced with the change of oil temperature, conservator plays oil storage and repairing, can guarantee that in fuel tank and is full of
Oil, simultaneously because having filled conservator, reduce the contact surface of transformer and air, and moisture, dust and the oxygen absorbed from air
Grease after change is all deposited in the depositor of conservator bottom, can also slow down the degradation speed of transformer oil significantly.For dry
Dry air, except dust, the respirator on conservator has played key.Current respirator typically uses UNICOM's extraneous air
The moisture in air is filtered with impurity with cotton using silica gel, such a mode is due to being directly to be communicated with air, therefore
Humid air in air can be entered in transformer oil unavoidably, cause transformer oil ageing, and dielectric strength reduces.So user
Need often to change silica gel and processing transformer oil, it is necessary to spend substantial amounts of energy periodic maintenance and maintenance conservator.
Utility model content
To solve the above problems, the utility model devises a kind of installation for transformer with piston respirator, structure letter
List, good airproof performance, contact of the insulator oil with air is avoided, and regular replacement and repair need not be carried out to it.
To achieve the above object, the utility model employs following technical scheme：A kind of transformation with piston respirator
Device conservator, including conservator shell, conservator support frame, oil level indicator and corrugated hose, between the conservator shell and conservator support frame
It is welded and fixed, and conservator support frame bottom is threaded hole, and oil-out and oil return opening are provided with the conservator shell, it is described to exhale
Suction pipe road one end is fixedly welded on conservator shell side, and the other end connects piston respirator, the piston respirator by flange
Including the piston cylinder being vertically arranged, the piston being arranged on inside piston cylinder, the filter cotton being arranged at piston cylinder port and protection
Cover, wherein the piston is symmetrical I-shaped structure, sealing ring is provided with each piston head, the piston cylinder is with preventing
Connected between shield by three support bars, dust-proof cotton is arranged between piston cylinder and protective cover
As a kind of further improvement of the installation for transformer with piston respirator of the utility model：The filter cotton is put down
It is layered at piston cylinder port.
As a kind of further improvement of the installation for transformer with piston respirator of the utility model：The corrugated hose
Diameter is slightly less than piston diameter.
Beneficial effect
Compared with prior art, the utility model has the advantages that：
First, installation for transformer described in the utility model, the respirator of conservator replaces traditional silicon with piston respirator
Glue adsorbs respirator, makes conservator interior insulation body oil isolation air, in fully sealed position, efficiently avoid insulator oil
Oxidation, also, using the use for having prevented silica-gel desiccant after piston respirator, it is a large amount of using not only being needed during silica-gel desiccant
Human resources need it to be dried heating to change silica gel, and after silica gel is changed, virtually again add energy
Consumption, resource can be saved to greatest extent using piston respirator.
Second, installation for transformer described in the utility model, the protective cover design at the top of respirator can prevent rainwater from entering
Enter in piston cylinder, cross and filter pulp tiles to the impurity such as dust can be avoided at piston cylinder port to enter in piston cylinder, to piston head
Cause to wear.
