Abstract
A method for monitoring a circuit breaker and an apparatus and an internet of things using the same. The method includes: obtaining a first data set representing force applied to a fixed point of an element of an actuating mechanism of the circuit breaker in present operation cycle, judging a health condition of the circuit breaker in consideration of normal operating condition related parameters of the element according to a history profile when the circuit breaker operated normally and current operating condition related parameters of the element in the present operation cycle extracted from the force represented by the first data set, and generating a signal indicating the health condition of the actuating mechanism of the circuit breaker. The force applied to the fixed point of the actuating mechanism of the circuit breaker, which corresponds to a health condition of mechanical parts of the circuit breaker as a whole, is selected as an indicator for condition monitoring of the mechanical parts of the circuit breaker. The operating condition related parameters derived from the measurements of the force are considered giving a relatively high accurate judgement of the whole mecha…
