The invention provides a hot test device for a circuit breaker, which can provide accurate data for a research and development test of the circuit breaker and can be used for setting a parameter of a production line of the circuit breaker according to the data when a large batch of circuit breakers are produced. The hot test device for the circuit breaker comprises a circuit breaker loading assembly, a circuit breaker clamping assembly, a power supply assembly and a control system, wherein the circuit breaker loading assembly is used for conveying the circuit breaker to a working station; the circuit breaker clamping assembly is used for locating and clamping the circuit breaker in the working station; the power supply assembly is electrically connected with the circuit breaker so as to provide currents with various values to the circuit breaker; the circuit breaker loading assembly, the circuit breaker clamping assembly, the power supply assembly and the circuit breaker are respectively connected with the control system; and the control system controls the circuit breaker loading assembly, the circuit breaker clamping assembly and the power supply assembly to act and obtains or sets a performance value of the circuit breaker. The invention also relates to a test method and a regulating method for the hot test device of the circuit breaker.
Description
technical field [0001] The invention relates to the field of circuit breaker production or experimentation, in particular to a thermal testing device for a circuit breaker and a testing method and an adjustment method for the thermal testing device for a circuit breaker. Background technique [0002] The technology of electrical equipment is developing rapidly, and the replacement of circuit breakers commonly used in electrical equipment is also very rapid. Before the newly developed circuit breaker is mass-produced, it is usually necessary to conduct research and development experiments on the circuit breaker to test various performance parameters of the circuit breaker, such as: on-off indicators, and more specifically, such as the current value passed to the circuit breaker, How long it takes for the circuit breaker to trip. [0003] In the prior art, there is no device specially designed for thermal testing of circuit breakers under development. The heat testing device...
