电子分级开关
摘要：
本发明涉及一种用于调节电压的分级开关，其在调节变压器上具有半导体开关单元（S1.1，S2.1；S1.2，S2.2,；...；S1.6，S2.6），该调节变压器具有调节绕组，其中设置两个并联的负载支路（1，2），在所述负载支路中多个半导体开关单元分别设置成串联电路。在这两个负载支路之间交替地并联设置调节绕组（W1，W2，W3）的部分以及电桥（B1，B2），使得通过将在两个负载支路中的所述半导体开关单元相应接线，调节绕组的部分可任意地接入或断开。
摘要（英）：

The invention relates to an electronic tap changer for voltage regulation, comprising semiconductor switch units (S1.1,..., S1.6; S2.1,..., S2.6) on a regulating transformer having a regulating winding, wherein two parallel load branches (1, 2) are provided, in each of which several series-connected semiconductor switch units are arranged. Parallel between the two load branches, alternating parts of the regulating winding as well as bridge circuits are provided such that by corresponding wiring of the semiconductor switch units in both load branches, the parts of the regulating wiring can be operated at will in a subtractive and/or additive manner.
