Abstract
The invention relates to a self-balancing transformer of a regulating coil on a side column and belongs to the transformer technical field. The technical scheme includes that a magnet exciting coil (1) of the transformer is arranged on a main column (6), the magnet exciting coil is incorporated into the regulating coil (2) which is arranged on the side column (7) through a leading wire, and the transformer performs excitation through the regulating coil; when the transformer works under a certain tap, working current only flows through the tapping range of an accessed part of the regulating coil and reverse working current is enabled to flow through the tapping range of an non-accessed part of the regulating coil by adjusting the number of turns and winding directions of the magnet exciting coil; and self-balance of ampere turns of the regulating coil on the side column is achieved by arranging the wire gauge and configuration mode of the regulating coil. The self-balancing transformer of the regulating coil on the side column has the advantages of simplifying wiring of the transformer and saving the space of the transformer, the raw materials and the artificial cost.
Description
Technical field
The present invention relates to a kind of other post voltage regulation coil self-balancing type transformer, belong to the transformer technology field.
Background technology
At present, in high-power transformer, when range of regulation larger, when the pressure regulation number of taps is more, independently voltage regulation coil is set usually, and because minute wiring is more, electric pressure is high, so outlet is comparatively complicated, thus this type of voltage regulation coil be enclosed within on the other post more, and on the other post of transformer overlap coil and must realize ampere-turn equilibrium, so, the background technology method is that magnet exciting coil is set separately on other post, in order to the magnetic potential that balance is produced by voltage regulation coil, finally reaches other post magnetic potential balance.On the other hand, the range of regulation of transformer determines the voltage regulation coil number of taps, and then determines the number of turn, structure and the arrangement mode of voltage regulation coil.For the voltage regulation coil of traditional structure, for range of regulation and the number of taps that satisfies the transformer technology protocol requirement, each tapping range should guarantee enough numbers of turn and current capacity in the voltage regulation coil, and transformer is only worked under a certain tap, then voltage regulation coil also only accesses the tapping range of part, then this part tapping range flows through operating current, and in most situation, tapping range and no current that voltage regulation coil does not access part pass through.But in order to guarantee transformer when the work of this tap, the voltage and current of transformer meets design requirement, and then not access the number of turn of part tap the same with current capacity with the number of turn of access part tap with current capacity for voltage regulation coil.Therefore the voltage regulation coil of background technology structure certainly will cause the waste of raw material and cost of labor.
Summary of the invention
The purpose of this invention is to provide a kind of other post voltage regulation coil self-balancing type transformer, arrange under the prerequisite of independent voltage regulation coil at satisfied other post, do not arranging in the situation of independent excitation coil at other post, make other voltage regulation coil that post overlaps itself realize ampere-turn equilibrium, namely overlap the magnetic potential balance of coil on the other post, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is:
Post voltage regulation coil self-balancing type transformer by a kind of, the magnet exciting coil of transformer is arranged on the principal post, the voltage regulation coil by by lead-in wire magnet exciting coil being incorporated on the post, transformer is by the voltage regulation coil excitation; When transformer was worked under a certain tap, the tapping range that voltage regulation coil only accesses part flow through operating current, the number of turn by adjusting magnet exciting coil and around to, the tapping range that makes voltage regulation coil not access part flows through the reverse operation electric current; By arranging wire gauge and the arrangement mode of voltage regulation coil, realize the ampere-turn equilibrium of voltage regulation coil on the other post itself again.Voltage regulation coil is satisfied outside the demand of pressure regulation, can also accomplish the voltage regulation coil ampere-turn equilibrium, and then reach the purpose of other post magnetic potential balance.
Patent of the present invention is improved energized circuit, and magnet exciting coil is enclosed within on the principal post, for conserve space and raw material, adopts the neutral point voltage regulating mode, is arranged on the insulation level of magnet exciting coil on the principal post in order to reduction.
The present invention arranges under the prerequisite of independent voltage regulation coil at satisfied other post, is not arranging in the situation of independent excitation coil at other post, makes other voltage regulation coil that post overlaps itself realize ampere-turn equilibrium, namely overlaps the magnetic potential balance of coil on the other post.Because transformer is only worked under a certain tap, so voltage regulation coil only accesses the tapping range of part and flows into operating current, so the tapping range that can utilize voltage regulation coil not access part flows through the reverse operation electric current, then by selecting voltage regulation coil wire gauge and arrangement mode, just can make on the other post institute overlap voltage regulation coil realization ampere-turn equilibrium itself by rational wiring again.Reach in tapping range as much as possible, to allow and all pass through electric current in the voltage regulation coil, and then simplify wiring, save the space, the purpose of economical with materials.
Good effect of the present invention is: the present invention has simplified transformer connection, has saved spatial transformer, has saved raw material and cost of labor.
