Description

Transformer Lifting Tools on Pole

technical field

The utility model relates to the field of electric installation equipment, in particular to a transformer hoisting tool on a pole.

Background technique

The number of pole-mounted transformers is large and the distribution area is wide. Its operation and maintenance have always been the focus of the power supply unit. Since a small number of transformers are located in places that are inaccessible or far away from the road, it is impossible to use a crane to replace or hoist the transformer after it fails. Core handling.

For this kind of transformer station area where cranes cannot be used for operations, when the transformer fails, if it is necessary to lift the core, it is necessary to install a cross arm above the transformer, and then use the lifting hoist to lift the core. When the method is applied, it is necessary to apply for a power outage on the high-voltage line; and when the transformer is damaged and needs to be replaced, it is also necessary to use this method to lift the transformer, and rely on manpower to pull the transformer obliquely with ropes and then put it on the ground. This method is time-consuming and laborious. It is also easy to cause damage to the transformer.

The disadvantages of the existing hoisting methods are mainly reflected in: 1) the resulting power outage range is large; 2) it takes a long time to remove and install the distribution transformer; 3) the labor intensity of the operators is high.
