Circuit breaker characteristic test method and device

Abstract

The invention discloses a circuit breaker characteristic test method and device. The method comprises the steps that S1, the model of a to-be-tested circuit breaker is acquired; s2, testing the circuit breaker according to the model of the circuit breaker and acquiring test data; and S3, obtaining a function test standard corresponding to the circuit breaker model according to the circuit breaker model, and judging whether the circuit breaker is qualified or not according to the function test standard and the test data. It can be seen that whether the test data is qualified or not can be automatically judged, the mode of manually checking the test standards one by one is replaced, the workload of testers can be reduced, and the test time is saved.

Description

technical field [0001] The invention relates to the technical field of electrical testing, in particular to a method and device for testing the characteristics of a circuit breaker. Background technique [0002] The test sequence of traditional high-voltage switch mechanical characteristics is: open the high-voltage switch panel, clamp the locking electromagnet with a clip to unlock the locking electromagnet; find the functional pin numbers of the energy storage motor, closing coil and opening coil in the secondary drawing; mechanical characteristics The output end of the instrument leads out the test line; the test line is clamped to the pin of the high-voltage switch aviation male plug; the energy storage motor is manually stored; the high-voltage switch realizes the closing and opening functions of the high-voltage switch; the multimeter test line is connected Aviation male plug pin, measure the resistance of closing coil and opening coil. [0003] This test method has s...

Problems solved by technology

[0003] This test method has shortcomings: it is necessary to open the high-voltage switch panel to unlock the locking electromagnet, which has potential safety hazards and troublesome operation. It is necessary to find the function pin serial number in the secondary drawing of the high-voltage switch, which will consume too much time and need to be completed by professionals. It is necessary to use more wire clips to connect the pins of the aviation male plug of the high-voltage switch. It is easy to cause wrong connection between the wire clip and the pin, and short-circuit between the wire clip and the adjacent pin, which will cause personal injury, damage to the high-voltage switch and damage to the mechanical characteristic instrument. Manual energy storage many times, there are potential safety hazards and the speed is slow. To measure the resistance of the closing coil and the opening coil, a multimeter test line must be used to connect the pins of the aviation male plug. It needs to be completed by two people, and it needs to be checked manually Test data and test standards, to judge whether the test results are qualified, need to manually record the test data and other issues, resulting in inconvenient and time-consuming overall testing operations

[0004] For this reason, the prior art proposes a test device that stores the serial numbers of the function pins corresponding to the signals of high-voltage switches of various types. The model outputs the corresponding control signal to complete the test of the high-voltage switch, but the device can only complete the test, and cannot make a judgment on the test result. It still needs to manually check the test results one by one, which is time-consuming and laborious.
