    摘要： The invention relates to a switching arrangement (15) with a pre-selector (28) for a power transformer (10, 40) which has multiple windings (12, 14). The pre-selector is designed to optionally connect at least one first winding (12) to one of the two end contacts (30, 32) of at least one second winding (14). At least one first switch is arranged in the connection between the preselector (28) and the first winding (12), thereby allowing the pre-selector to be switched in an arc-free manner and thus in a gas-free manner as well.

    摘要翻译： 本发明涉及一种具有用于具有多个绕组（12,14）的电力变压器（10,40）的预选器（28）的开关装置（15）。 预选器被设计成可选地将至少一个第一绕组（12）连接到至少一个第二绕组（14）的两个端部触头（30,32）之一。 至少一个第一开关布置在预选器（28）和第一绕组（12）之间的连接中，从而允许预选器以无电弧的方式被切换，并因此以无气体的方式被切换。
