Development and Application of Triangular Main Transformer On-load Tap Changer Hoisting Equipment for Overhaul

On-load tap changer is an important part of transformer. It playing role in voltage regulation, and its safe stable operation affects the reliability power supply grid. The has to maintenance after a certain number operations. In process, there are problems such as long time consumption low efficiency. On this basis, paper proposes development on main transformer on-load hoisting equipment. been verified practice that equipment can significantly shorten working improve efficiency under premise ensuring work safety.
