Abstract (en)
[origin: WO2012126685A1] The invention relates to a load stepping switch for switching over between taps of a control winding of a stepped transformer without interruption, wherein fixed step contacts are arranged in at least one horizontal plane in a wall of an insulating-material cylinder or on an insulating-material frame and are electrically connected to the taps, wherein a rotatable switching shaft is arranged in the center, said switching shaft having, for each horizontal plane of fixed step contacts on a contact support, mechanical contacts which can each be connected to the fixed step contacts, and wherein at least one contact on the contact support is electrically connected to the load discharge line by means of at least one interposed transition resistor (Rü1, Rü2). The transition resistor (Rü1, Rü2) comprises, in each case, a meandering wire helix (3) which is clamped and fixed by means of at least two resistor holders (6) which are composed of insulating material. The at least two resistor holders (6) of each transition resistor are attached to a shell-like resistor support (10) which is composed of insulating material and the resistor support (10), for its part, is attached to the switch pillar with which it shares a contour.
