[0002] The coil is an important component of the transformer. After the coil is wound, in order to ensure that the coil can withstand the axial force during the short circuit and meet the requirements of the axial size, the coil must be compressed. For small and medium-sized coils, screw rods are generally used. , however, the currently used screw-type coil compression device usually has a complicated installation method of the screw, or a complicated compression operation using the screw, and it is difficult to achieve synchronous rotation of multiple screws (usually four)

The invention discloses a transformer coil pressing device, and belongs to the technical field of transformer production. The device comprises a base, upright posts, a cushion block, a coil, a pressure pad, a pressure beam and a compression bolt. The upright posts are arranged on the base, the cushion block is arranged in the center of the base, the coil is arranged on the cushion block, the pressure pad is arranged on the coil, the pressure beam is arranged to the upright posts and on the pressure pad, and the compression bolt is arranged on the upright post above the pressure beam. The basecomprises a platform, corner blocks and positioning holes, wherein the four corners of the platform are each provided with one corner block, and each corner block is provided with one positioning hole. The number of the upright posts is four, and each upright post is installed in one positioning hole. A pair of positioning blocks is installed in a 90-degree empty space between the screw rod and the positioning hole, and a locking nut is installed at the top of the screw rod and used for pressing the pressure beam. The pressure beam comprises a circular truncated cone, an extension beam and a sleeve, and the circular truncated cone is located on the pressure pad. The compression bolt is a non-standard bolt and comprises a threaded area, a hexagonal head, a through hole and a stress application rod, wherein the threaded area is in threaded fit with the circular truncated cone center hole.
Description
technical field [0001] The invention belongs to the technical field of transformer production, in particular to a transformer coil pressing device. Background technique [0002] The coil is an important component of the transformer. After the coil is wound, in order to ensure that the coil can withstand the axial force during the short circuit and meet the requirements of the axial size, the coil must be compressed. For small and medium-sized coils, screw rods are generally used. , however, the currently used screw-type coil compression device usually has a complicated installation method of the screw, or a relatively complicated compression operation using the screw, and it is difficult to achieve synchronous rotation of multiple screws (usually four). Contents of the invention [0003] The present invention provides a transformer coil pressing device to solve the above-mentioned problems in the background technology. [0004] The technical problem solved by the present ...
