Abstract
The utility model relates to a kind of current compensation structure that is installed on converter transformer, described current compensation structure comprises and is fixed on the other post compensating plate of the other post in left and right, the iron yoke compensating plate that is fixed on the stem compensating plate of stem and is fixed on iron yoke, and three kinds of compensating plates are combined to form loop.The utility model thinking is ingenious, simple in structure, utilizes the feature that copper coin resistance is little to design current compensation structure, thereby has reduced the loss that lead-in wire magnetic field produces, and avoids the generation of local overheating, guarantees converter transformer safe operation.
Description
Technical field
The utility model relates to a kind of converter transformer, is specifically related to a kind of current compensation structure that is installed on converter transformer.
Background technology
Converter transformer has large-scale on-load voltage regulation ability, and its pressure regulation number of leads is far more than common power transformer, so the magnetic field that produces of its pressure regulation lead-in wire wants large many with respect to common power transformer.According to electromagnetic induction principle, when the magnetic flux through a closed conductor circuit changes, in conductor, just there will be induced current.The alternating magnetic field that electric current in change of current modified tone voltage lead wires produces, through structural member and silicon steel sheet, induces larger induced current in structural member loop, silicon steel sheet loop, produces a large amount of losses, very easily produces local overheating, the safe operation of harm converter transformer.
Summary of the invention
For the problems referred to above, the utility model provides a kind of current compensation structure of guaranteeing converter transformer safe operation.
For addressing the above problem, the technical scheme that the utility model is taked is: described current compensation structure comprises a current compensation loop, this current compensation loop by being fixed on the other post compensating plate of the other post in left and right, the iron yoke compensating plate that is fixed on the stem compensating plate of stem and is fixed on iron yoke connects to form.Described compensating plate should adopt the material that resistance is little to make; thereby the induced current overwhelming majority that lead-in wire magnetic field produces circulates by compensating plate loop; induced current in structural member loop and silicon steel sheet loop just becomes very little; it is very little that its loss becomes equally, meanwhile, and because compensating plate plate resistance is minimum; the loss that induced current produces in compensating plate loop is also very little; thereby reduced the loss that lead-in wire magnetic field produces, avoided the generation of local overheating, guaranteed converter transformer safe operation.
In order to guarantee that compensating plate and silicon steel sheet fully insulate, described current compensation structure is arranged between silicon steel sheet loop and structural member loop, insulate out each other by insulating part.
Described stem compensating plate, other post compensating plate and iron yoke compensating plate two ends are equipped with connecting hole.Such three kinds of compensating plates can form loop, the induced current circulation that the magnetic field of being convenient to go between produces.
Preferably, each described compensating plate is copper coin.
The utility model thinking is ingenious, simple in structure, utilizes the feature that copper coin resistance is little to design current compensation structure, thereby has reduced the loss that lead-in wire magnetic field produces, and avoids the generation of local overheating, guarantees converter transformer safe operation.
