RESISTOR DEVICE WITH STACKED ANNULAR RESISTANCE ELEMENTS

摘要

Disclosed is a stacked resistor device particularly for high-voltage installations. The resistor device includes inner and outer annular resistance elements of different diameters which are adjacently disposed along a common axis to form a stack. The resistance elements are electrically connected by annular-shaped contact elements. The contact elements include an annular recess of larger diameter on one side for receiving the outer resistance element and an annular recess of smaller diameter on the other side for receiving the inner resistance element, and include a central cutout through which a clamping sleeve of plastic material is inserted. Bushings and clamping parts are disposed at opposed ends of the sleeve to clamp the resistance elements and contact elements together to form the stacked resistor device. The contact elements not only provide for electrical connections between resistance elements but also provide a bearing surface for the resistance elements so that in cooperation with the bushings inserted into opposite ends of the clamping sleeve, the resistance elements and contact elements are clamped together into a compact and mechanically strong resistor device.
