摘要： The invention relates to a method for monitoring contact consumption in multiple contact switches of the load-switching type, wherein the selection and the switching is carried out in one step by the movement of switching contacts and which therefore do not have a separate diverter switch. Every time the multiple contact switch is actuated, the load current is measured. The corresponding, previously stored rated stage voltages for the current switching and information on whether it was shifted “up” or “down”, are used to calculate the switching currents of the breaking contacts, the consumption rates are determined on the basis thereof and the volume consumption is accumulated. Said accumulated value is compared with a previously determined threshold value; once this threshold value is reached, warning messages or other messages are generated.
摘要翻译：本发明涉及一种用于监测负载切换型多接点开关中的接触消耗的方法，其中选择和切换通过开关触点的移动在一个步骤中进行，因此不具有单独的切换开关。每次启动多接触开关时，都会测量负载电流。用于当前切换的相应的预先存储的额定级电压以及关于“向上”还是“向下”的信息用于计算断开触点的开关电流，消耗速率基于此确定，并且体积消耗积累。将所述累积值与先前确定的阈值进行比较; 一旦达到此阈值，就会生成警告消息或其他消息。

摘要： A method of monitoring contact burnoff in tap changers operating under load in which the load current is measured and for nominal variation of the voltage of the particular tap parameters are stored which are used to calculate the burnoff rate per contact per switching operation. From these values the cumulative burnoff rate of both the switching contact and resistance contact are determined and compared with limits or threshold values.

摘要： The invention relates to a load selector for step switches in step transformers with two movable selector contacts. A suitable vacuum switch is located downstream of the first movable selector contact to switch the load current and a suitable switch for switching the compensation current is located downstream of the second movable selector contact. Both of the selector contacts are independently movable in such a way that one of the selector contacts moves slowly and the other selector contact rapidly moves or jumps between positions. The sequence of operation of the selector contacts is independent of the switching direction.

摘要： The invention relates to an on-load tap changer for switching among winding taps of a step transformer without interruption. According to the invention, in each auxiliary current branch of the on-load tap changer, which operates with vacuum switching tubes as switching elements, additional switches are provided in series with the vacuum switching tubes and the respective winding tap. Said additional switches cause a complete galvanic isolation of the vacuum switching tubes in the auxiliary current branches in steady-state operation.
