[0002] The main function of the transformer core is to guide the current, so as to transmit the change of the current to the copper coil to realize the measurement and transformation of the current. In the power system, the transformer core converts high voltage and large current into low voltage and small current through the principle of electromagnetic induction, so as to facilitate the normal operation of the measurement and protection equipment. The heat treatment of the core can make the orientation of the core grain more consistent, thereby improving the magnetic conductivity of the core and reducing the flux loss and iron loss.

[0003] In the prior art, when the transformer core is heat treated, the position of the high-frequency coil heater is fixed, and the transformer core needs to be clamped and then placed inside the high-frequency coil heater for high-temperature heat treatment. After the heat treatment, the transformer core is clamped out for cooling. When the core is clamped and placed inside the high-frequency coil heater, the position of the core is easily offset, and the center of the core and the center of the high-frequency coil heater cannot be on the same straight line, resulting in different distances between the edge of the core and the circumferential surface of the high-frequency coil heater, resulting in different heating effects on the core surface and the time required to reach the heating temperature, which can easily cause uneven heating of the core, uneven internal structure and hardness of the core, and affect its strength and service life.

In this transformer core heat treatment equipment, the conveyor belt installed on the frame facilitates the transportation of several mounting seats, improving the conveying efficiency during the heat treatment of the core body. The placement seat fixed on the hollow rotating shaft facilitates the placement of the core body. When the several pressing and positioning components arranged on the placement seat work, they can firmly press the core body on the placement seat, preventing position deviation during heat treatment. At the same time, the position of the core body can be automatically adjusted, ensuring that the center of the core body, the hollow rotating shaft, and the center of the high-frequency coil heater are on the same straight line. This can achieve the purpose of keeping the distance between the circumferential surface of the core body and the inner wall of the high-frequency coil heater consistent.

The second sliding sheet fixed on the L-shaped cleaning block can be elastically connected to the cleaning bracket. When the rotating plurality of fourth resistance rods are in contact with the second L-shaped resistance strips fixed on the second sliding sheet, the fourth resistance rods can be in contact with the second L-shaped resistance strip fixed on the second sliding sheet, so that the L-shaped cleaning block can be intermittently reciprocated on the surface of the core body, further improving the cleaning effect.

[0035] A U-shaped contact frame 33 is arranged inside the mounting seat 3. A guide rod 34 is fixed to the U-shaped contact frame 33. The guide rod 34 is elastically connected to the mounting seat 3 through an eighth spring 35. One side of the U-shaped contact frame 33 is in contact with the first contact wedge 22, and the other side of the U-shaped contact frame 33 is in contact with the second contact wedge 26.

[0036] A hollow seat 43 is fixed on the mounting seat 3. A piston piece 44 is slidably connected inside the hollow seat 43. A piston rod 45 is connected to the piston piece 44.

The water outlet of the hollow seat 43 is connected to the nozzle 46 through a pipeline.

[0037] To improve the quality and heat-receiving effect of the heat treatment of the iron core body 6, it is necessary to clean the oxides and stains on the iron core body 6. When the first abutting bracket 10 is abutted by the second abutting rod 16, it can drive the trapezoidal abutting piece 29 to move horizontally synchronously, prompting the trapezoidal abutting piece 29 to abut against the third abutting rod 27, causing the third abutting rod 27 to move vertically upward, and the sixth spring 28 to store energy. During the upward movement of the third abutting rod 27, it abuts against the third abutting bracket 30, prompting the third abutting bracket 30 to drive the third abutting wedge 32 to move horizontally on the mounting seat 3, achieving the purpose of the third abutting wedge 32 abutting against the U-shaped abutting bracket 33, enabling the guide rod 34 to slide horizontally on the mounting seat 3, and at the same time, the eighth spring 35 to store energy. When the U-shaped abutting bracket 33 moves horizontally, it can achieve the purpose of abutting against the first abutting wedge 22 and the second abutting wedge 26, prompting the grinding bracket 19 to drive the L-shaped grinding piece 21 to abut against the surface of the iron core body 6, and the fourth spring 20 to store energy. When the iron core body 6 rotates, the oxides and impurities on the surface of the iron core body 6 can be removed, improving the thermal conductivity and ensuring the heat treatment effect. At the same time, the cleaning bracket 23 drives the L-shaped cleaning block 25 to abut against the surface of the iron core body 6, and the fifth spring 24 to store energy, capable of cleaning the impurities ground off, reducing the residual impurities on the surface of the iron core body 6, and improving the heat-receiving effect.

The L-shaped fixing piece can facilitate the fixing of the fiberglass cleaning sheet. The fiberglass cleaning sheet has good high-temperature resistance, so that when the high-frequency coil heater 15 is reset after heating, the L-shaped cleaning block 25 contacts the heated iron core body 6, avoiding deformation caused by high temperature and affecting the use effect.

[0038] To improve the cleaning effect of the L-shaped cleaning block 25, it is necessary to spray a decontamination agent onto the L-shaped cleaning block 25. Refer to Figure 1-Figure 7The liquid inlet of the hollow seat 43 is connected to the decontaminant conveying equipment, and the decontaminant can be quantitatively conveyed into the hollow seat 43. When the cleaning bracket 23 moves, it automatically drives the piston rod 45 and the piston plate 44 to move in the hollow seat 43, prompting the decontaminant to be conveyed from the liquid outlet of the hollow seat 43 through the pipeline to the nozzle 46, and sprayed toward the L-shaped cleaning block 25. When the L-shaped cleaning block 25 contacts the surface of the core body 6, the stains can be removed by the decontaminant, which can greatly improve the quality and effect of the heat treatment of the core body 6.
