Description

Technical Field

[0001] The present invention relates to the technical field of transformer body compression, and in particular to a high voltage transformer body compression structure and a use method thereof. Background Art

[0002] Transformer is the basic equipment for power transmission and distribution, and is widely used in industry, agriculture, transportation, urban communities and other fields. Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, secondary coil and iron core. The main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc.

[0003] At present, investigations have found that there are many cases of transformers being damaged due to the unreasonable design of the transformer body compression structure and the non-standard body compression process, which leads to the decrease of the transformer's short-circuit resistance. This defect is due to the fact that after the transformer is assembled, it needs to be placed in a drying room for drying. However, the coils wound on the surface of the transformer will shrink after being dried, resulting in gaps in the shrunk coils, which reduces the transformer's ability to resist sudden accidents and poses a safety hazard to the operation of the transformer. Therefore, a high voltage transformer body compression structure capable of improving safety is now designed to solve such defects. Summary of the invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-voltage transformer body clamping structure, including a load-bearing base plate, a transformer body and a pressure top plate, the load-bearing base plate and the pressure top plate are respectively located at the top and bottom of a circular limit frame, the top of the load-bearing base plate is fixedly connected to the circular limit frame, the transformer body is located on the inner side of the circular limit frame, the front and rear parts of both sides of the top of the load-bearing base plate and the pressure top plate are provided with limit holes that penetrate to the bottom, a support rod is arranged on the inner side of the limit hole, the upper and lower parts of the surface of the support rod are respectively provided with a first thread groove and a second thread groove, the surface of the second thread groove is threadedly connected to a first thread sleeve, and the surface of the first thread groove is threadedly connected to a second thread sleeve.

[0006] Preferably, both sides, front and rear of the bottom of the pressure top plate are fixedly connected with a pressure sensor body, the top of the pressure top plate is fixedly connected with a data display screen through an opening, and the pressure sensor body and the data display screen are fixedly connected via a data line.

[0007] Preferably, the bottom of the pressure sensor body is fixedly connected to a cross-connecting plate via a fixing block, and both sides of the bottom of the cross-connecting plate are fixedly connected to arc-surface compression columns via fixing blocks, a compression sleeve is sleeved on the surface of the arc-surface compression column, and a butterfly spring sheet is arranged inside the compression sleeve and at the lower part of the arc-surface compression column.

[0008] Preferably, guide slide grooves are provided on both sides of the compression sleeve, guide slide blocks are fixedly connected to both sides of the arc surface compression column, and the guide slide blocks are slidably connected to the guide slide grooves.

[0009] Preferably, a circular pressure plate is fixedly connected between the bottom ends of several compression sleeves via a fixing plate, a pressing block used in conjunction with the transformer body is fixedly connected to the bottom of the circular pressure plate, and several pressing blocks are arranged in a ring shape.

[0010] Preferably, an upper lifting frame is provided on the top of the pressure top plate, and the front and rear parts on both sides of the top of the upper lifting frame are rotatably connected with a threaded handle barrel through an opening, and the threaded handle barrel is threadedly connected to the first thread groove.

[0011] Preferably, both sides of the top of the upper lifting frame are fixedly connected with handle frames through fixing plates.

[0012] Preferably, the bottom end of the support rod is threadedly connected to a base sleeve that cooperates with the second thread groove.

[0013] The present invention also discloses a method for using the high voltage transformer body compression structure, which specifically comprises the following steps: S1. Before use, first insert the four support rods into the inner side of the limiting sockets on the surface of the load-bearing base plate, then screw the first threaded sleeve to connect with the second threaded groove, so that the load-bearing base plate is balanced and installed through several first threaded sleeves, and then screw the base sleeve to connect with the second threaded groove. Then the staff uses the base sleeve to place the load-bearing base plate and the support rods on the ground and then place the transformer body inside the circular limiting frame. Then, the pressure top plate is connected to the support rods using the limiting sockets and then lowered to make the pressing block press the circular limiting frame. Then, A plurality of second threaded sleeves are threadedly connected with the first threaded groove, and the plurality of second threaded sleeves are continuously screwed to make the pressure top plate push the pressure sensor body and the arc surface compression column downward, and the arc surface compression column will compress the butterfly spring sheet under the limit of the guide slide groove, and when the butterfly spring sheet is compressed, the circular pressure plate and the pressing block will press the transformer body tightly to bind the coil on the surface of the transformer body from the bottom, and then the transformer body is installed, and then the threaded handle is threadedly connected with the first threaded groove to install the upper lifting frame on the top of the pressure top plate, and then go to step S2; S2. After all the equipment is installed, the staff will lift the equipment with the handle frame and send it to the drying room for drying. During the drying process, the coil will be dried and shrunk, resulting in gaps between the coils. At this time, the compressed butterfly spring sheet inside the compression sleeve will stretch out, but because the top of the butterfly spring sheet is supported by the arc compression column, the bottom ends of several butterfly spring sheets will push the circular pressure plate and the pressing block to compress the coil on the surface of the transformer body, thereby ensuring that no gaps will appear. After the drying is completed, the equipment will be taken out; S3. After drying, the equipment uses several pressure sensor bodies and data display screens. Since the butterfly spring sheet is located between the arc compression column and the circular pressure plate and squeezes each other, the pressure sensor body will display the value on the surface of the data display screen after being subjected to pressure. The staff can use the data display screen to observe whether the pressure of the transformer body after drying meets the requirements.

[0014] Beneficial Effects The present invention provides a high voltage transformer body compression structure and a method for using the same.

After the transformer body is dried, these structures can use the elastic force of the butterfly spring sheet after pre-compression to compress the shrunk coil again, thereby ensuring the anti-suddenness of the transformer body, reducing the occurrence of unexpected situations, and effectively improving safety.

[0015] (2) The high-voltage transformer body compression structure and its use method are characterized by installing a pressure sensor body connected to a pressure top plate on the top of the arc compression column and using it in conjunction with a data line and a data display screen. The arrangement of these structures enables the staff to quickly obtain whether the compression force of the transformer body after drying meets the surface requirements by using the data display screen after drying the transformer body, thereby effectively improving the product qualification rate and work efficiency.
