Method for Evaluating the Mechanical Performances of a Switchgear Device and Switchgear Device for Implementation of Said Method

摘要

A method for evaluating the mechanical performances of a switchgear apparatus comprising at least one pole having: a pair of contacts; a drive mechanism of a support arm of a first contact comprising: a rotary pole shaft and at least one connecting rod which couple the drive mechanism to the support arm, an energy storage system designed to cause movement of said arm to close the contacts. The method consists in measuring the angle of rotation of the pole shaft during closing of the contacts; reconstituting at least two specific values from the measurements and comparing them with an operating reference to diagnose the mechanical wear performances of the drive mechanism with respect to a comparative state.
