Description

A transformer group for power transformation

technical field

Its requirements are getting higher and higher. At present, combined transformers combining voltage transformers and current transformers have gradually appeared on the market. Such transformer groups are generally larger in size and heavier in weight. This makes the installation work very difficult, and because the transformer groups used for power transformation are fixedly installed on the utility poles, it is easy to cause inconvenient wiring, and when the cables are tight, it is not easy to adjust the position of the transformer groups. Adjustment causes the cable to be stretched too tightly, and the existing transformer group is in a suspended state after the cable is connected, and is easy to swing with the wind, causing the connection to shake back and forth and easy to wear, which affects the service life.
