Problems solved by technology

Among them, the manual lifting operation is difficult, inefficient and has hidden dangers of personnel injury; crane lifting requires a large operating space, and the crane body is close to the electrified body, and there are potential electrical safety hazards; hydraulic lifting and complete machine return to the factory are expensive.
[0004] Moreover, in the process of hanging the core, when the inner core is taken out and cleaned, it is necessary to keep the inner core stable and not shake as much as possible, and one person must be there to monitor it, which increases manpower and safety hazards

Description

technical field [0001] The invention relates to the technical field of transformer maintenance, in particular to a hoisting and maintenance tool for a voltage regulating switch. Background technique [0002] The transformer on-load tap changer is a voltage regulating device used to change the connection position of the transformer winding. In order to ensure the normal operation of the transformer on-load tap changer, it is necessary to regularly carry out core inspection and maintenance on the transformer on-load tap changer. [0003] In the prior art, the maintenance of the transformer hanging core is mainly carried out by manual lifting, crane lifting, hydraulic lifting, and return of the complete machine to the factory. Among them, manual lifting operation is difficult, inefficient and has hidden dangers of personnel injury; crane lifting requires a large operating space, and the crane body is close to electrified bodies, which poses potential electrical safety hazards; ...
