Abstract
The utility model discloses a double -voltage dry type transformer belongs to the substation equipment field, and its structure includes coil A, coil B and coil C, coil A, coil B and coil C through changing winding hookup group, do not be provided with firstly first and first two on coil A, coil B and coil C's top, respectively be provided with a tail head in coil A, coil B and coil C's lower part. The utility model discloses a double -voltage dry type transformer compares with prior art, has characteristics such as reasonable in design, simple structure, easily processing, simple to operate, and not only the cost is reduced can effectually guarantee moreover that the voltage ratio satisfies national standard and user's requirement.
Description
Technical field
The utility model relates to converting equipment field, specifically a kind of double-voltage dry type transformer.
Background technology
Current domestic existing electrical network mainly 10kV and 6kV distribution system, configure transformer of the prior art routinely, 6kV transformer can only be powered from 6kV electrical network, when line voltage becomes 10kV, namely electric power system changes, user must purchase the transformer being applicable to 10kV electric power system again, and such overlapping investment must cause and greatly waste.
Summary of the invention
Technical assignment of the present utility model is for above weak point, provides a kind of double-voltage dry type transformer that a kind of cost is low, easy for installation.
The utility model solves the technical scheme that its technical problem adopts: this double-voltage dry type transformer comprises loop A, coil B and coil C, described loop A, coil B and coil C are by changing winding connecting group grade, be respectively arranged with first first and first two on the top of loop A, coil B and coil C, be respectively provided with a tail head in the bottom of loop A, coil B and coil C.
First or first two, the head of described loop A, coil B and coil C is separately installed with binding post.
Described first two is connected by coupling bar with between tail head.
Described loop A, to be connected by coupling bar between coil B and the tail head of coil C.
A kind of double-voltage dry type transformer of the present utility model compared to the prior art, have reasonable in design, structure simple, be easy to processing, the feature such as easy for installation, not only reduce cost, and effectively can ensure that voltage ratio meets national standard and user's requirement.
Accompanying drawing explanation
