Abstract
The aim of the utility model is to provide a three-phase integral transformer, which can effectively settle the problems of large material consumption, high production cost, large space occupation, inferior system stability, etc. The utility model relates to three-phase integral transformer which comprises a housing that is internally provided with three fixed voltage transformers. The three voltage transformers are connected one another in parallel. According to the utility model, three single-phase voltage transformers are equipped in a same housing. The three-phase integral transformer has the advantages of: effectively reduced material loss, reduced production cost, capability for installation without large space, and good system stability.
Description
Technical field
The utility model relates to a kind of three-phase coenosarc instrument transformer.
Background technology
Along with high speed development of national economy; various places improve constantly the demand of electric power; transmitting electric power generally is the conveying of growing distance with high voltage style, selects suitable potential device for use in the places such as terminal residential block or factory that power, and potential device is with using voltage transformer usually.The structure of voltage transformer is identical with common transformer with operation principle, and it is made up of iron core, winding, secondary winding, binding post and an insulating support substrate etc.A winding of voltage transformer is connected to the line voltage or the phase voltage of system, and its insulation should be decided with the height of real system voltage.One time winding has the more number of turn, and the secondary winding number of turn is seldom supplied with the potential winding of instrument or relay.In generalized information system, often need to use three single-phase 220kV voltage transformers to come supporting use, required three housings of product, material is wasteful, has increased production cost, and it is too many to take up room simultaneously, and the stability of a system is poor.
The utility model content
The purpose of this utility model provides a kind of three-phase coenosarc instrument transformer, and the material that can effectively solve prior art is wasteful, production cost is high, and space hold is many, problems such as stability of a system difference.The utility model relates to a kind of three-phase coenosarc instrument transformer, comprise housing, described housing internal fixation has three voltage transformers, and described three voltage transformers are connected in parallel to each other, described housing is provided with three binding posts, and three voltage transformers are connected on three binding posts.The utility model is installed in three single-phase potential transformers in the same housing, has effectively reduced spillage of material, has reduced production cost, and need not very large space can install, and the stability of a system is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Comprise housing 1 among the figure, described housing 1 internal fixation has three voltage transformers 2/3/4, described three voltage transformers 2/3/4 are connected in parallel to each other, described housing is provided with three binding posts 5/6/7, three voltage transformers are connected on three binding posts, and three voltage transformers are outwards powered by three binding posts.The each several part of a winding of three voltage transformers comprise that binding post all insulate over the ground, and insulation level is consistent with rated insulation level.The neutral-point solid ground of a winding of three voltage transformers.Three single-phase potential transformers are installed in the same housing, can effectively reduce spillage of material, have reduced production cost.
Claims (3)
1. a three-phase coenosarc instrument transformer comprises housing, it is characterized in that: described housing internal fixation has three voltage transformers.
2. a kind of three-phase coenosarc instrument transformer as claimed in claim 1 is characterized in that: described three voltage transformers are connected in parallel to each other.
3. a kind of three-phase coenosarc instrument transformer as claimed in claim 1 is characterized in that: described housing is provided with three binding posts, and three voltage transformers are connected on three binding posts.
