Abstract
The utility model discloses an error compensation device of a voltage transformer. The device comprises the voltage transformer, wherein an insulator is arranged in the voltage transformer, a first iron core is arranged in the insulator in a sealed mode, and insulating copper, a second winding, an insulating layer and a first winding are sequentially wound on the first iron core from inside to outside. The device is characterized in that a second iron core wound through an enameled wire is arranged in the insulator and under the first iron core in a suspended mode, the second iron core is connected with the second winding through a copper wire, a compensation coil is wound on the second iron core, and the two ends of the compensation coil are led out to an N end and a P end of the outer side of the insulator through a first flexible copper strand and a second flexible copper strand. According to the error compensation device of the voltage transformer, the compensation coil is arranged at the outer end of a large iron core, so that position voltage of the inside of the large iron core is reduced, damages to insulation protection are avoided, different voltage error compensation values can be obtained more effectively, and fine compensation requirements are met.
Description
Technical field
The utility model relates to a kind of error-compensating apparatus of voltage transformer, belongs to instrument transformer and makes the field.
Background technology
During the error-compensating apparatus of original voltage transformer by a bucking coil around the home on the insulated copper surface of core exterior surface, be positioned at the next door of secondary winding, in the situation that occur after the product cast that error is undesirable to be adjusted by bucking coil, time error reaches optimum state like this.But this kind mode around the home on iron core, so that the winding quantity of iron core increases, installs very inconveniently bucking coil, and can destroy the insulating protection effect.
The utility model content
The technical problem that the utility model solves is to provide a kind of error-compensating apparatus of voltage transformer.
The technical solution that realizes the utility model purpose is:
A kind of error-compensating apparatus of voltage transformer, comprise voltage transformer, described voltage transformer inside is provided with insulator, the insulator inner sealing is provided with iron core one, be wound with successively from inside to outside insulated copper on the described iron core one, secondary winding, insulating barrier and a winding, it is characterized in that: inner at described insulator, the unsettled iron core two that is provided with the enamelled wire coiling in the below of iron core one, iron core two is connected with secondary winding by copper cash, be wound with bucking coil on the iron core two, the two ends of described bucking coil are respectively by annealed copper strand wire one, annealed copper strand wire two leads to insulator exterior " N " end and " P " end.
The error-compensating apparatus of voltage transformer of the present utility model is contained in bucking coil the outer end of large iron core, reduced the position pressure of large core interior, avoid the damage to insulating protection, and more effectively obtained different compensation of voltage error values, can satisfy meticulousr compensation requirement.
