Abstract
The invention relates to a multifunctional transformer for a power plant and belongs to the technical field of transformers. The invention adopts the technical scheme that: a low-voltage winding LV1 (4), a low-voltage winding LV2 (5), a voltage-regulating winding TV1 (2), a high-voltage winding (1) and a voltage-regulating winding TV2 (3) are sequentially arranged from the inside to the outside; the high-voltage winding (1) is connected with the voltage-regulating winding TV1 (2) in series and then connected with a non-exciting tapping switch to realize three different high-voltage rated voltages; and the voltage-regulating winding TV1 (2) is connected with the voltage-regulating winding TV2 (3) in series and then connected with an on-load tapping switch to realize voltage on-load regulation under different rated voltages. For the high voltage windings, three different generator outlet voltages can serve as the rated voltages, the high-voltage windings can perform voltage on-load regulation in a certain range, and the multifunctional transformer for the power plant can output two different voltages for the power plant. The multifunctional transformer for the power plant can serve as a standby of the transformer for the power plant having different generator outlet voltages or different voltages for the power plant.
Description
Technical field
The present invention relates to a kind of Multifunctional transformer for power plant, belong to the transformer technology field.
Background technology
The outlet voltage of different power plants generator can be different because of generator manufacturing age or power resources difference, and the rated voltage of the service power in different power plants also may be different.Increase along with power plant quantity, this difference situation between the power plant is just more and more, and common transformer can not be general, can not do standby for the station transformer in different power plants simultaneously, when the station transformer in different power plants breaks down, can not in time replace failure transformer.
Summary of the invention
The purpose of this invention is to provide a kind of Multifunctional transformer for power plant, do standby for the station transformer in different power plants simultaneously, when the station transformer in different power plants breaks down, can in time replace failure transformer, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is: a kind of Multifunctional transformer for power plant, low pressure winding L V1, low pressure winding L V2, pressure regulation winding TV1, high pressure winding and pressure regulation winding TV2 arrange from inside to outside successively, the first series voltage-regulating winding of high pressure winding TV1, connect off circuit tap changer, realize three kinds of different high pressure rated voltages, pressure regulation winding TV1 is series voltage-regulating winding TV2 again, is connected with on-load shunting switch, realizes having to carry based on the voltage under different rated voltages regulating.
The low pressure winding is in series by low pressure winding L V1 and low pressure winding L V2, and its mesolow winding L V1 only has the shunting switch of a gear by connection, realize two different output voltages.
Good effect of the present invention: adopt the mode of connection of the present invention and winding arrangement, high pressure can be accepted three kinds of different generator outlet voltages as rated voltage, and the high pressure winding can carry out the on load voltage of certain limit to be regulated, and can export the multi-functional station transformer that two kinds of different power plant use voltage.This transformer can provide standby for the station transformer in generator outlet voltage difference or power plant's utilization voltage different power plant.
