本发明涉及一种根据反应器开关原理的分接开关，用于通过真空开关单元进行不间断负载切换。 根据本发明，该分接开关具有三个分离的绝缘轴; 第一这些绝缘轴的用于致动的所有相的可动的选择器触点，这些绝缘轴的第二用于致动所述可动预选器接触和这些绝缘轴的第三用来致动，一方面可动旁路接触，而在另一相应的相位相关的真空开关单元。 通过其中各个绝缘轴的相应的旋转运动，根据每个独特的开关序列产生一个单一的，横向布置的齿轮用于依次致动绝缘轴。

The invention relates to a tap changer according to the reactor switching principle for uninterrupted load transfer by vacuum switching cells. According to the invention this step switch on three separate insulating shafts; The first of these insulating shafts serves to actuate the movable selector contacts of all phases, the second of these insulating shafts serves to actuate the movable preselector contacts and the third of these insulating shafts serves to actuate the movable bypass contacts on the one hand and the respective phase associated vacuum switching cell on the other hand. For actuating the insulating shafts turn serves a single, laterally disposed gear, through which the corresponding rotary movements of the individual insulating shafts are generated according to the switching sequence to be realized.
