Method and system for measuring mechanical characteristic of breaker

The invention relates to a method and system for measuring the mechanical characteristic of a breaker. The method for measuring the mechanical characteristic of the breaker comprises: acquiring a pull rod force signal, a main contact displacement signal, and a main shaft angular displacement signal in an opening/closing process of the breaker; processing the pull rod force signal, the main contact displacement signal, and the main shaft angular displacement signal to obtain pull rod force data, main contact displacement data, and main shaft angular displacement data; performing analysis according to the pull rod force data, the main contact displacement data, and the main shaft angular displacement data to obtain a mechanical characteristic parameter. The method for measuring the mechanical characteristic of the breaker solves a problem of the detection of the mechanical characteristic of a breaker in which a spring is arranged in a transmission mechanism.
