摘要： A step switch for a step transformer (1), preferably for a cast-resin encapsulated step transformer, has one-phase identical step switch modules (3.1, 3.2, 3.3) having each all means required for switching the load and its own housing for enclosing said means. The step switch modules are linked each by a driving shaft (4.1, 4.2, 4.3) to a motor drive (5). Each step switch module is directly arranged with no connecting lines on the output lines of a step winding or is connected thereto over a connecting terminal (2.1, 2.2, 2.3) and has fastening elements having the same geometrical configuration, as well as electric connecting elements (3.1.1, 3.1.2, 3.1.3) which are electrically connected with the step contacts to be wired inside the housing or which extend themselves into the inside of the housing through a recess (3.4) in the housing and directly form the wirable step contacts.

摘要： The invention relates to a load selector for step switches in step transformers with two movable selector contacts in which there is a suitable vacuum switch downstream of the first movable selector contact to switch the load current and a suitable switch for switching the compensation current downstream of the second movable selector contact and in which both selector contacts are independently movable in such a way that one of them moves slowly and the other in jumps and their sequence is independent of the switching direction.

摘要： The invention concerns a switching arrangement for load change-over switches of step switches and for selector switches, wherein two switching contacts movable in two directions are present. The first switching contact is in the form of a main switching contact and is connected to the load derivation by means of a first vacuum switchgear cell. The second switching contact is in the form of a resistance switching contact which is likewise connected to the load derivation by means of a series connection comprising a second vacuum switchgear cell and a transition resistor. Both the main and the resistance switching contacts can be moved independently of one another and without mutual coupling or influence. The main switching contact always reaches the new fixed contact abruptly and independently of the switching direction before the resistance switching contact leaves the previous fixed contact.

摘要： The invention relates to an on-load tap changer of a step switch with an energy accumulator having a lifting slide continuously movable by a drive shaft and a depressor actuating a switching shaft. According to the invention, on the switching shaft there is an axially movable insert bearing cam discs to actuate vacuum switches and mechanical switching components. Depending on the switching direction, i.e. the linear movement of the lifting slide of the energy accumulator, the switching insert is taken to an upper or lower position on the switching shaft in such a way that different cam discs become operative. It is possible with this on-load tap changer to make asymmetrical circuits in which there is the same sequence of switchgear to be moved or actuated regardless of the switching direction.
