Central Point On Load Tap Changer
Tap changer operation principle is that the electrical motor , it is turned on, through gearing of two-level worm and worm wheel, drives arm which in its rotation process, pushes the turning arm to pull the spring to accumulate energy. When the turning arm overpasses the “dead point” position where it is lined up with the stretched spring, the pulled spring is immediately released, which makes turning arm to fast dial the wheel via a dialing disc. The wheel drives the moving contacts assembly through the main shaft to move from one position to the next. Because the transition resistor is added between main contacts and transition contacts which operate one by one in certain sequences therefore the main contacts can move from one tap to the adjacent one without current interruption.

Dandong is a great ancient city with long history. In the 1980s, Liaoning Jinli Electric Power Electrical Appliance Co., Ltd went on the road for hard entrepreneurship with strong beliefs. During more than 30 years encouraging and growing development in competitive market conditions, we accumulate rich experience, Jinli has become famous tap changer company of China and integrated R&D and manufacture enterprise function.
