The invention relates to an overload property verifying device for a breaker. The verifying device comprises a base, an adjusting screw head, a motor, an air cylinder A for controlling the motor to retract along an axial direction of a motor output shaft, and a transmission device for transmitting current to the breaker, wherein the adjusting screw head is matched with the motor output shaft in a linkage manner; the base is provided with a slide platform capable of sliding along the direction of the motor output shaft; the slide platform is provided with a beaker mounting seat and the beaker mounting seat is matched with the slide platform in a linkage manner; and the overload property verifying device for the breaker further comprises a control device for controlling the switching-on and switching-off of the breaker and a positioning device for controlling the slide distance of the breaker mounting seat. With the adoption of the technical scheme, the overload property verifying device for the breaker provided by the invention can be used for automatically verifying a plurality of breakers in sequence, so that verification of the breaker is very convenient.
Description
technical field [0001] The invention relates to a circuit breaker overload characteristic verification device. Background technique [0002] In the past, people usually clamped the circuit breaker with welded electrodes to check the overload characteristics of the circuit breaker, and then applied the required current to the closed circuit breaker through the current output device composed of a voltage regulator and a resistance transformer. 1. When the loading current of the circuit breaker reaches the specified time, manually adjust the adjusting screw in the circuit breaker to the tripping position of the circuit breaker to see if the tripping time is within the specified time range, so as to judge whether the circuit breaker is qualified. [0003] Later, through continuous exploration and research, a circuit breaker overload characteristic verification device was produced. It includes a base, an adjusting screw head, and a motor. The adjusting screw head is coordinated ...
