Description

[0002] Dry-type transformers have been widely used due to their advantages of flame retardancy and maintenance-free. To ensure the stability of the voltage at the low-voltage output end, a voltage regulating switch is usually set on the high-voltage side of the dry-type transformer. The windings on the high-voltage side of the dry-type transformer are connected by copper tubes, and the amount of copper tubes used is relatively large.

Currently, copper bar processing equipment is mainly used to bend copper tubes. Although the design size requirements of the copper tubes can be met, the phenomenon of internal concavity will occur at the bent parts of the copper tubes as Figure 1 shown, resulting in the reduction of the internal cavity space of the copper tube at the bent part, leading to the blockage of the internal cavity, poor air circulation, local heating of the used copper tube, affecting the normal and stable operation of the dry-type transformer, and the existing copper bar processing equipment is relatively bulky and not convenient to use in a relatively narrow environment.
