三角形联结的移相变压器

本发明涉及一种三角形联结的移相变压器，属于变压器制造技术领域。技术方案是：所述在三角形连接的电源侧或负荷侧绕组的内部内接一个负荷侧或电源侧三角形绕组，该三角形绕组的每相绕组与电源侧或负荷侧的对应相绕组为自耦接线结构，自耦接线的串接绕组为带抽头的调压段，通过调节抽头位置实现小角度的移相以及小幅度的降或升压。本发明的有益效果是：可以在小角度移相的同时解决线路需要小幅度的变压的需求，该结构的移相变压器为单器身结构，绕组数量少，接线简单，比实现同等功能的传统双器身结构的移相变压器要大为简化，降低了设计、制造难度，提升了系统运行的可靠性。 The invention relates to a phase-shifting transformer in triangular connection, and belongs to the technical field of transformer manufacturing. According to the technical scheme, a load-side or power-side triangular winding is internally connected into a power-side or load-side winding in triangular connection, each phase winding of the triangular winding and a corresponding phase winding of the power side or the load side are of a self-coupling wiring structure, a series winding of the self-coupling wiring is a voltage regulating section with a tap, and small-angle phase shift and small-amplitude step-down or step-up are realized by adjusting the position of the tap. The phase-shifting transformer has the beneficial effects that the requirement
