Background technique
Transformer be electric system most expensive and a most important one piece apparatus and structure is most complicated, failure rate compared with
High equipment, the safe operation of transformer is to guaranteeing that power supply reliability is of great significance;The load ratio bridging switch of transformer is
The mostly important component of transformer, the load ratio bridging switch well run are the bases of transformer safety operation, therefore will be to having
On-load shunting switch periodically carries out suspended core maintenance;Currently, 110kV transformer, which has load to decompose switch all, to be lifted by crane using crane, cost
High, low efficiency, it is exactly a danger source that crane, which enters substation, and crane lifting error is big, is easily damaged switch, increase need not
The economic loss wanted, and increase the insecurity factor of site operation;If being lifted by crane without using crane, needs three people while lifting
Switch, and there are grease stains on transformer at this time, artificially lift switch quite dangerous.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provide it is a kind of work efficiency is high, and can be completed without using crane
A kind of combined type hoisting of on-load tap changers of transformers suspended core maintenance.
The technical solution of the present invention is as follows: a kind of combined loaded tap-changer boom hoisting, structure are as follows: support rod (1)
