CDF2
Wukai
1. Overview
The CDF2 on-load tap-changer motor-drive unit is mainly used as a mechanism to drive and control the tap-changer action, so that the tap-changer switches from one tap position to another, thus achieving voltage regulation.
The mechanical and electrical components required to operate the on-load tap-changer are installed in the motor drive unit and electrical interlocking circuits are used.
Generally, the motor-drive unit is supplied as an accessory to the on-load tap-changer unit as a complete set.
