Design of 110 kV Cable Laying Bushing Lifting Device for Transformers
As the operating years of the main transformer increase,the sealing ring gradually ages and encounters oil leak-age defects.It is often necessary to lift the sleeve to replace the sealing ring.The current operation method is to use a crane to lift and replace the casing,which poses a high risk and the indoor enclosed main transformer room cannot be used.This paper studies and designs a transformer 110 kV cable type bushing lifting device,which is set on the bushing through a sleeve ring and is positioned and locked by bolts and locking seats.The hook component above can adjust horizontal posi-tion and height,aiming to solve the problem of replacing the sealing ring of the transformer 110 kV cable type bushing lifting seat,improving work efficiency and avoiding the risk of accidental electric shock when using a crane.The applica-tion of this device can facilitate guaranteeing safety of power equipment and personnel,as well as providing necessary tech-nical support for lifting and maintenance of power grid equipment.
