The invention provides a testing method for a circuit breaker. The method comprises: step S1: assembling a basic circuit breaker; step S2: combining and punching; step S3: spraying a barcode; step S4:punching and riveting; step S5: pasting a sealing plug; step S61: testing the time delay characteristic; step S62: testing the instantaneous characteristic; step S64: testing the pressure resistancecharacteristic; and step S65: testing the mechanical operation. According to the testing method for the circuit breaker, the process is reasonable, the detection efficiency is high, the controllability is strong, and the product quality is stable. The invention also provides an automatic testing device for a circuit breaker based on the above testing steps, which has reasonable layout, compact structure and high automation efficiency.
Description
Technical field [0001] The invention relates to the field of automation, in particular to an automatic test device and a test method for circuit breakers. Background technique [0002] Circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions, and can close, carry and break current under abnormal circuit conditions (including short circuit conditions) within a specified time. Circuit breakers can be used to distribute current without frequently starting asynchronous motors. They can protect power lines and motors. They can automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse switch and The combination of overheating and underheating relays, etc., generally does not need to change parts after breaking the fault current. The circuit breaker production process generally includes two stages of assembly and inspection, but the existing cir...
