Problems solved by technology
However, if the coil inserted into the iron core is exposed to the air for a long time, and the iron yoke is not inserted immediately, the coil will be damp, and the coil height direction will rebound. The large rebound will cause the later plug-in work to be impossible, which will directly affect the transformer body. assembly
The current method is to install all the high and low voltage side clamps and side beams, and then use a jack to press down the height of the coil, which requires a lot of work.

The invention relates to the field of transformer coil installation, in particular to an anti-rebound pressing tool for transformer coils, and solves the problem that at present, coil rebound is treated by means of installing all of high and low voltage side clamps, side beams and the like prior to pressing the coils in height with a jack, however workload is large. The anti-rebound pressing tool for the transformer coils comprises two press bolts, a straight rib plate, a pressing plate and a shaft; the straight rib plate is arranged between the two press bolts; thread bushings are arranged at two ends of the straight rib plate and sleeve the corresponding press bolts; the pressing plate is arranged in the middle of the straight rib plate; a shaft fixing hole is arranged in the middle of the pressing plate; the shaft is inserted into the shaft fixing hole. The anti-rebound pressing tool for the transformer coils is simple and light in overall structure and convenient to install, when the transformer coils are damped and rebounded, rebound amount of the coils can be effectively controlled under the action of the tool, the mode of pressing down by the jack at the present can be replaced completely, and labor intensity is reduced greatly.
Description
technical field [0001] The invention relates to the field of transformer coil installation, in particular to a transformer coil anti-bounce compression tooling. Background technique [0002] After the transformer coil is assembled as a whole, it needs to be vacuum dried and press-fitted to ensure that the overall height of the coil meets the design requirements. However, if the coil inserted into the iron core is exposed to the air for a long time, and the iron yoke is not inserted immediately, the coil will be damp, and the coil height direction will rebound. The large rebound will cause the later plug-in work to be impossible, which will directly affect the transformer body. assembly. The current method is to install all the high and low voltage side clamps and side beams, and then use a jack to press down the height of the coil, which requires a lot of work. Contents of the invention [0003] In order to solve the above technical problems, the present invention provid...
