Description

Technical Field

[0001] This utility model relates to the technical field of transformer core auxiliary devices, and in particular to a reliable transformer core impregnation mechanism. Background Technology

[0002] Transformers are indispensable and crucial equipment in power systems, and their performance directly affects the stability and reliability of the power system. During the transformer manufacturing process, the impregnation of the iron core is a key step, aiming to improve the insulation performance and mechanical strength of the iron core, reduce electromagnetic noise, and prevent the iron core from rusting.

[0003] Transformer cores need to be impregnated with varnish during the production process. The existing method for impregnating the core involves the core being carried into the impregnation tank by a conveyor device. After impregnation, the conveyor device removes the impregnated core from the other side. However, the core's travel distance is relatively long, resulting in a long processing time and cumbersome operation. Furthermore, due to the prolonged immersion in varnish, the varnish on the conveyor device accumulates, which can damage the equipment, waste materials, and increase production costs. Therefore, this method is not very practical. Utility Model Content

This optimization not only reduces varnish waste but also lowers equipment maintenance costs, extends equipment lifespan, and thus reduces production costs, thereby enhancing practicality.

This design enables rapid entry and exit of the transformer core in the varnish-impregnating tank, reducing the core's movement time. Traditional methods require a long conveying path for the core to complete the impregnation process, while this design, through rotation and lifting movements, allows for faster impregnation.

[0028] This utility model discloses a reliable transformer core impregnation mechanism. Its working principle is as follows: First, the equipment is fixed to the ground using four sets of fixed threaded rods, four sets of nuts, and a mounting plate. Then, the equipment position is set via an upper-level device. When core clamping is required, the first servo motor is activated to rotate the lifting threaded rods, thereby moving the first slider, sleeve, and top plate upwards. Next, a reduction motor is activated to adjust the direction of the cylindrical outer shell, lifting assembly, top plate, and first electric cylinder. Simultaneously, the rotation of the reduction motor drives the first and second transmission wheels to rotate, which in turn drives the encoder output to rotate, ensuring the accuracy of the gripper's rotation position. Finally, two sets of double-acting electric cylinders are activated to move four sets of second pneumatic rods inwards to clamp the core. Two sets of clamping plates and six sets of clamping blocks hold the iron core. When the two sets of clamping blocks move, the two sets of clamping plates can be reinforced and stabilized by three sets of sleeves and six sets of sliding rods. Then, the geared motor drives the output end to rotate in the opposite direction. Then, the first servo motor drives the gripper and the top plate to move downward. Then, the first electric cylinder drives the first pneumatic rod, gripper and iron core to be immersed in the paint soaking tank for paint soaking of the iron core. Then, the first electric cylinder drives the first pneumatic rod, gripper and iron core to move upward. Then, the first servo motor drives the entire equipment to move upward. Then, the geared motor drives the equipment to rotate in the direction. Then, the first electric cylinder drives the gripper and iron core to move downward and place the iron core on the lower device. Then, the gripper releases the iron core. Then, the first electric cylinder drives the gripper to move upward and then performs the paint soaking treatment of the second set of iron cores.
