Abstract:
A closure resistor assembly for high voltage electrical gear, the assembly comprising:a case having one end closed by a cover;a multiplicity of resistive electrical components, disposed within said case and aligned in a row along an axis; anda mechanism which exerts a compression force on the resistive electrical components along the axis so as to maintain electrical contact between them, wherein the mechanism which exerts said compression force comprises a rigid tube disposed inside said case and within which said resistive electrical components are stacked, and an energy-storing floating structure placed inside the tube at one end of the row of said resistive electrical components, said floating structure being constituted by a first piece disposed between said end of the row of said resistive electrical components and a second piece that is mounted in a fixed manner inside the tube, together with a spring that is kept in compression between the first and second pieces, said first piece also being mounted so as to have limited movement between two abutments that are spaced-apart along the axis and that are constituted by the ends of a slot of the tube, said slot having passing therethrough a movable stud which is secured to said first piece.
