Abstract

The invention discloses a method for acquiring a travel curve of a circuit breaker operating mechanism. The method comprises the following steps: building an assembly body model of the circuit breaker operating mechanism; importing the assembly body model into an ADAMS to obtain a multi-body dynamic model, and setting parameters of all parts in the multi-body dynamic model and constraint relations among all the parts in the ADAMS; setting the magnitude of spring and friction acting force in the multi-body dynamic model, and performing simulation; and setting observation points, and obtaining a travel curve and a speed curve of the multi-body dynamic model of the operating mechanism. A series of problems of difficulty in arrangement of friction coefficients between mechanisms, limitation of experimental sites, difficulty in equipment acquisition, difficulty in sensor installation and the like can be solved, and a travel curve can be simply and accurately acquired.

Description

technical field [0001] The invention relates to the technical field of circuit breaker fault diagnosis, in particular to a method for obtaining a stroke curve of an operating mechanism of a circuit breaker. Background technique [0002] The circuit breaker is an important switching device in the power supply system. In addition to breaking and closing the circuit, it can also isolate the faulty circuit in time to prevent the scope of the accident from further expanding and ensure the reliable operation of the system. If the circuit breaker fails to open or close properly or malfunctions or refuses to operate, it will cause a short-term power outage on the line, or endanger the stability of the system, induce more serious power outages, and cause huge economic losses. Therefore, considering the important role of the circuit breaker in the power supply system, it is very necessary to carry out fault diagnosis on it. [0003] According to statistics, mechanical failure account...
