The technical scheme includes that the auto-coupling and induction on-load voltage-regulating transformer comprises a constant magnetic flux body (1) and a variable magnetic flux body (7), wherein the constant magnetic flux body is provided with a low-voltage winding (5), a voltage-regulating winding (4), a common winding (3) and a series winding (2); the variable magnetic flux body is provided with an induction winding (8) and an excitation winding (9); the iron cores of the constant magnetic flux body and the variable magnetic flux body are in a single-phase three-column structure, the structural dimensions of the constant magnetic flux body are larger than the structural dimensions of the variable magnetic flux body, and the variable magnetic flux body is orthogonally arranged at the end part of the constant magnetic flux body. As a voltage-regulating coil is not connected with a high-voltage coil and a medium-voltage coil, and one end of the voltage-regulating coil is connected with a neutral point instead, the insulation level of a switch is the insulation level of the neutral point, so that the insulation level of the switch is very low, the insulation level of the switch is reduced to 72.5 kV grade from 500 kV, and the cost is reduced.
Description
Technical field:
The utility model relates to a kind of self coupling, induction on-load tap-changing transformer, belongs to technical field of transformer manufacturing.
Background technology:
Respond to load tapchanging autotransformer, be mainly used in when transformer high, that middle piezoelectricity pressure ratio is more approaching and middle piezoelectricity pressure is higher.The problem that background technology exists is that the insulation level of loaded switch is had relatively high expectations, and generally needs the horizontal 500kV level of switch insulation, and technology difficulty is big, the cost height.
The utility model content:
The utility model purpose provides a kind of self coupling, induction on-load tap-changing transformer, reduces the insulation level of loaded switch effectively, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of self coupling, induction on-load tap-changing transformer, and comprise permanent magnetic flux device body and become magnetic flux device body, permanent magnetic flux device is provided with low pressure winding, pressure regulation winding, common winding, series connection winding on one's body; Become the magnetic flux device and be provided with induction winding, field winding on one's body, the iron core of permanent magnetic flux device body and change magnetic flux device body is single-phase three pillar type structure, permanent magnetic flux machine body structure size becomes the end that magnetic flux device body quadrature is arranged at permanent magnetic flux device body greater than becoming magnetic flux machine body structure size.
Utilize permanent magnetic flux device body and become the neutral of magnetic flux device to be placed with load switch, be used for being pressed with voltage adjustment of on-load in the bight.
The series connection winding is connected with common winding and is the self coupling structure, and the pressure regulation winding is in parallel with excitation winding for the induction winding provides excitation, leads to intermediate voltage terminal after the induction winding is connected in the common winding head end.
The beneficial effects of the utility model are: change the effective turn of pressure regulation winding by loaded switch, thereby change the circle electromotive force of the excitation winding in parallel with it, the induced voltage of responding to winding like this also changes thereupon, presses the purpose of pressure regulation in the realization.Because voltage regulation coil directly is not connected on the high and medium voltage coil, but an end is connected neutral point, and the insulation level of switch is the insulation level of neutral point, so the insulation level of switch is very low, the switch insulation level is reduced to the 72.5kV level by the 500kV level, reduces cost.
