Abstract
The invention relates to a method for controlling an electrical switching module which can be displaced between an entry position and an exit position. The switching module comprises switching contacts of vacuum switching tubes; an isolating element which can be also be displaced in the switching module and comprises isolating contacts which can be connected to, and disconnected from, corresponding mating contacts inside an enclosed switchboard section, as required; and connector contacts and mating connector contacts in the low voltage range. The switching contacts of the vacuum switching tubes support the closing and opening processes, under the control influence of a closing spring which can be influenced by a closing catch (EK) and an opening spring which can be influenced by an opening catch, and prominent functional positions of the isolating position. Only the isolating contacts are disconnected from the mating contacts in a test position which is situated between the operational position and the isolating position. The connector contacts are also disconnected from the mating connector contacts in the isolating position of the isolating element. When the switching module is switched from the isolating position to the exit position, the closing spring and the opening spring are forced into an unstressed state. One such method is used to control displaceable switching modules in medium voltage switchboard sections.
