Embodiment Construction

[0029] The present invention will be further elaborated below in conjunction with the accompanying drawings of the description.

[0030] Such as Figure 1A ~ 1C As shown, a transformer coil annular axial compression device of the present invention is characterized in that it has a pressure plate 4 and an upper hanging plate 1, the two are connected by a chain 2, and the lower part of the pressure plate 4 is provided with multiple Adjust the pressure beam 3 of the position. The part of the lower part of the pressure plate 4 corresponding to the pressure beam 3 is provided with a pull-out structure. The pull-out structure includes a slide rail 5 and ferrules. The slide rail and ferrule are fixedly installed on the bottom surface of the pressure plate 4 along the radial direction of the pressure plate 4. 3 sides are slidably connected to the slide rail 5, and the pressure beam 3 is inserted into the ferrule.

[0031] Such as Figure 1C As shown, the ferrule includes two connec...

Abstract

The invention relates to an annular axial pressing device and an annular axial pressing method for a transformer coil. The annular axial pressing device is provided with a pressure plate and an upper hanger plate which are connected through a chain; and the lower part of the pressure plate is provided with a plurality of position adjustable pressure beams along the radial direction of the pressure plate. The method comprises the following steps: according to the inner diameter of a coil to be pre-pressed, adjusting the adjustable pressure beams of the annular axial pressing device; using a hoist to hoist the annular axial pressing device, and directly putting the annular axial pressing device on the section of the coil to be pre-pressed; controlling the pre-pressing time to be 10-20 minutes; and after the pre-pressing of the section of the coil is finished, hoisting and moving away the annular axial pressing device, so that the one-time pre-pressing process is finished. According to the annular axial pressing device and the annular axial pressing method, the pre-pressing process is realized in the coil winding process as well as after completion of winding and before demolding, so that the problem that the winding of the coil with a larger wire gauge or a special structure is not compact is solved.

Description

technical field [0001] The invention relates to a tool for manufacturing a transformer, in particular to a ring-shaped axial compression device and a compression method for a transformer coil. Background technique [0002] The transformer industry is developing rapidly, and user units have higher and higher requirements for the performance of transformer products. Therefore, according to the needs of users, we continue to develop innovative high-voltage, high-current large-capacity transformers and converter transformers. These transformers are also major products in national key projects. The coil wire structure of these products is complex, and it is difficult to ensure the axial tightness of the coil during the winding process. Especially when using a vertical winding machine, the axial tightness is the key control measure to avoid the wire segment from falling down and avoiding the short circuit of the wire segment. [0003] In view of the above reasons, it is necessary...
