Resistor assembly for tap changer and tap changer

A resistor assembly for a tap changer, the resistor assembly comprising:

• a resistor element, which is held by at least two resistor holders;
• a base plate with at least one opening and on which the at least two resistor holders holding the resistor element are arranged;
• a plurality of guides, respectively formed in each of the resistor holders and being configured to position a first end and a second end of the resistor element with respect to a longitudinal direction between the two resistor holders;
• and
• contact points of the resistor element, the contact points being respectively electrically contacted by contacts of the tap changer in a condition where the resistor element is inserted into the resistor holder,
• wherein each of the guides is formed as a slot with a closed end and an open end, and the slot is provided, at least in part, with a side wall which extends partially along the slot, wherein the resistor element is configured to be pushed in via the open end,
• wherein each of the guides comprises a holding element which is in the form of a reversibly and elastically pivotable leg with a snap-action hook provided at a free end, and
• wherein the snap-action hook secures the resistor element pushed into the guide and holds it in position.
