Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit breaker testing, in particular to a controller code test bench for electronic circuit breakers. BACKGROUND

[0002] Electronic circuit breakers can more accurately protect circuits and devices from electrical faults such as overloads and short circuits. To ensure the accuracy of the circuit breaker after manufacturing, a controller is used to connect the circuit breaker circuit board for testing. The tester connects the controller to the interface on the circuit breaker for power on, and during the process, rotates multiple knobs on the circuit board to adjust parameters such as rated current, loss time, short circuit short delay time, etc. The controller collects signals output by the circuit breaker from the interface to determine whether the circuit breaker has defects. After testing, the circuit breaker often needs to be adjusted to the preset parameters required by the customer for direct use. However, the existing test device requires the tester to use a screwdriver to manually adjust the angle by inserting it into the screw slot on the end face of the knob. Since the knob is small and delicate, the screwdriver can easily separate from the knob when rotating the knob. This operation is time-consuming and labor-intensive and difficult to accurately rotate the knob, resulting in a decrease in circuit breaker testing efficiency. Therefore, it is an urgent technical problem to design a controller code test bench for electronic circuit breakers that can easily adjust the circuit breaker knob and improve the rotation accuracy.
