Transformer workshops in power companies usually include winding groups, insulation groups, iron cutting groups, assembly groups, and experiment stations. The frequent replacement of transformers has a great test on the winding work. The winding work is to wind the copper wire into a coil according to the specified form, and the coil is divided into high-voltage and low-voltage. The machine winds a low-voltage coil, and another person uses another winding machine to wind a high-voltage coil on the low-voltage coil. The original traditional winding machines are all gear-driven, and their working efficiency is relatively low. The maximum speed is only 260r/min. If you want to adjust the speed during the coil winding process, you must stop the machine tool, and then use the gear lever to change the speed. gear, and then continue to work.
