Problems solved by technology
[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)

A transformer coil pressing device belongs to the technical field of transformer production, including a base, a column, a pad, a coil, a pressure pad, a pressure beam and a compression bolt. The column is installed on the base, the pad is placed in the center of the base, and the coil is placed in the center of the base. On the pad, the pressure pad is placed on the coil, the pressure beam is installed on the column and is located on the pressure pad, and the compression bolt is installed on the column above the pressure beam. The base includes a platform, corner blocks and positioning holes, each of the four corners of the platform has a corner block, and each corner block has a positioning hole. There are four uprights, and each upright is installed in a positioning hole. A pair of positioning blocks are installed in the 90° gap between the screw rod and the positioning hole, and a lock nut is installed on the top of the screw rod, and the lock nut is used to compress the pressure beam. The pressure beam includes a round table, an extension beam and a sleeve, and the round table is located on the pressure pad. The compression bolt is a non-standard bolt, and the compression bolt includes a threaded area, a hexagonal head, a through hole and a reinforcing rod, and the threaded area matches the thread of the center hole of the round table.
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 ...
