Miniature circuit breaker reliability test equipment

Abstract

The invention relates to miniature circuit breaker reliability test equipment which comprises a computer control cabinet, a data acquisition system, a test load adjustment impedance cabinet and a test port cabinet. The computer control cabinet is connected to the data acquisition system, the test load adjustment impedance cabinet and the test port cabinet. The computer control cabinet inputs a control power supply, and the test load adjustment impedance cabinet inputs a test power supply. Through the above, according to the miniature circuit breaker reliability test equipment, the all reliability tests of a miniature circuit breaker can be automatically completed, the accuracy and repeatability of a test result are ensured, the equipment is controlled by a computer, the operation is simple, the degree of automation is high, the equipment can be widely applied to electrical life, mechanical life and overload reliability test of various miniature circuit breakers, the automatic recording of test data and the automatic recording of fault data are realized, a test sample quits a test when the test sample is invalid or failed, and the test of other test samples is not affected.

Description

technical field [0001] The invention relates to the field of advanced manufacturing technology equipment, in particular to a miniature circuit breaker reliability test equipment, which belongs to intelligent electric appliance test equipment. Background technique [0002] Improving the reliability and economic benefits of energy supply has received more and more attention from the state. At present, the main direction of my country's power grid construction is the smart grid, that is, to enhance the security, stability and reliability of the power grid by improving the overall intelligence of the power grid. Smart grid devices will make the grid more reliable, efficient and controllable. As an important part of the smart grid user end, the miniature circuit breaker's reliability directly affects the stable operation of the system, production labor and home safety, so the reliability of the miniature circuit breaker is particularly important. In order to improve the reliabi...

Problems solved by technology

[0004] The miniature circuit breaker reliability test equipment in the prior art has a long test cycle due to the long test period of the miniature circuit breaker. Generally, the temperature rise, mechanical life, and electrical life tests take dozens of hours or even longer; To adjust the expected current, the tested product needs to be energized for a long time, and the expected current adjustment cycle is long and it is easy to damage the tested product. The tester needs to work in shifts and work for a long time. The test process is monotonous and boring, and the tester needs to manually adjust the load frequently and Repeated data measurement for a long time; a large amount of test data is not easy to save for a long time, human factors are large, and the test data is inaccurate; lack of remote monitoring and operation

Insufficient protection functions such as cabinet door opening and closing protection in the energized area, main switch chain protection, overheating protection, and automatic exit of failed test products; although it is controlled by an industrial computer or PLC, it is not a real-time operating system; the logic accuracy error of the measurement and control system is large
