Abstract
The utility model relates to a combined transformer fusing mechanism, in particular to a fusing mechanism of a booster transformer applied to wind power generation technique. The combined transformer fusing mechanism is characterized in that each phase line arranged at an output end of the booster transformer is connected with at least two fuses, and the at least two fuses are connected in parallel. The combined transformer fusing mechanism disclosed by the utility model utilizes a structure of parallel fuses so as to increase current in use, solve a problem that the current of a single phase of a transformer is too small when a single fuse is utilized, and have an excellent protection function on overload and short circuit of the transformer.
Description
Technical field
The utility model relates to the fuse body of the booster transformer that uses in the combined transformer fuse body, particularly wind power generation.
Background technology
Along with the fast development of wind power generation, the use of combined transformer also more and more widely.Overload and short circuit for to combined transformer play a good protection, the plug formula gamut protection fuse in the high-pressure side of transformer.Operational version in the past is that transformer every uses single fuse mutually; Along with the continuous increase of transformer capacity, the development of fuse can not be satisfied the needs that transformer capacity increases far away, single fuse use promptly occurs and flows through little problem single-phase the powering on of transformer.
Summary of the invention
The purpose of the utility model is: designs and a kind ofly can adapt to big electric current, thus the combined transformer fuse body that transformer overload and short circuit are played a protective role.
The technical scheme of the utility model comprises that each phase line that is installed in booster transformer (like wind power generation transformer) output connects at least two fuses, each fuse parallel connection.Generally speaking, each phase line of transformer output can be used two fuses, and the parallel connection of two fuses.
For said structure, each fuse that is connected with same phase line is installed on the same mounting panel with side.
The utility model adopts the structure of fuse parallel connection, uses after-current to increase, and has solved single fuse use and has flow through little problem single-phase the powering on of transformer, and transformer overload and short circuit are played a good protection.
