Abstract
The invention provides a body pressing structure of a 220kV transformer without a pressing nail structure, relating to the field of the 220kV transformer without the pressing nail structure. By the adoption of the body pressing structure, the problems that as the 220kV transformer without the pressing nail structure is large in the crosswise size of coils, and the position of an oil hydraulic cylinder is limited, the body of the transformer is nonuniformly pressed and the overall pressing effect is not good are solved. The body pressing structure of the 220kV transformer without the pressing nail structure comprises a clamp, a press fitting support and the oil hydraulic cylinder, wherein a clamp bolt hole is formed in the clamp; the press fitting support consists of a bending part and a horizontal straight part; the bending part is closely adhered to the clamp; the horizontal straight part presses the top part of the oil hydraulic cylinder; a reinforcing plate is arranged between the side face of the bending part and the upper side face of the horizontal straight part; the bending part is provided with a press fitting bolt hole which is matched with the clamp bolt hole and is fixed through a bolt. The body pressing structure is simple in structure and can be flexibly adjusted; according to actual pressing demands, the oil hydraulic cylinder can be flexibly located, so that the body of the transformer is uniformly pressed, and the overall pressing effect of the body of the transformer is improved.
Description
Technical field
The present invention relates to the 220kV level field transformer of pin structure with no pressure, particularly relate to a kind of device body compressing structure of 220kV level transformer of pin structure with no pressure.
Background technology
The machine body structure kind of transformer is a lot, and different machine body structures has different device body compressing method.220kV transformer has a kind of pin structure device body with no pressure, this structure device body press-fits more difficult, reason is that coil width is very large to size, and the position placing oil hydraulic cylinder only has several position, make device experience pressure uneven, some places pressure is excessive, some places also do not compress, and overall compression effect is bad, cannot meet the required requirement evenly compressed of transformer body.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of device body compressing structure of 220kV level transformer of pin structure with no pressure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of device body compressing structure of 220kV level transformer of pin structure with no pressure, and it comprises folder, press-fits support and oil hydraulic cylinder composition; Wherein, described folder is provided with folder bolt hole; The described support that press-fits is made up of bending part and the portion being anyhow arranged on position, bending part middle reaches; Described bending part is close to side and the bottom surface of folder; Described portion is anyhow pressed in the top of oil hydraulic cylinder; The side of described bending part and be anyhow also provided with stiffener between portion's upper side; Described bending part is also provided with press mounting bolt hole and folder bolt hole and fits through bolt and be fixed.
Described bending part and anyhow portion are structure as a whole.
The compacted position of described oil hydraulic cylinder on coil adjusts by installation site adjustment folder press-fiting support.
Operation principle: the side bending part press-fiting support being close to folder, and will support be press-fited by bolt and folder is fixed together, place oil hydraulic cylinder in the below press-fiting support, oil hydraulic cylinder is placed on position coil needing compress; Start oil hydraulic cylinder, oil hydraulic cylinder provides pressure to coil, and the reaction force of coil to oil hydraulic cylinder is delivered to and press-fits support, finally passes on folder, reaches the object of compactor body; According to the difference of the position that need compress, multiple oil hydraulic cylinder can be set and press-fit support, and arbitrarily can adjust the position of oil hydraulic cylinder, making device experience pressure evenly.
Beneficial effect of the present invention: the structure of the device body compressing structure of the 220kV level transformer of a kind of pin structure with no pressure of the present invention is simple, can adjust flexibly, can according to the compression demand of reality, the position of oil hydraulic cylinder is set flexibly, make device experience pressure evenly, improve the effect that device body entirety compresses.
