Equipment use

The molded case circuit breaker delayed action characteristics test bench is a device used to test the delayed action characteristics of molded case circuit breakers. This equipment is used to test the delayed action characteristics of molded case circuit breakers, and has completed 2 (2.5) ln multi-pole series. The equipment complies with the testing requirements of national and international standards such as GB14048.1/IEC60947-1, GB14048.2/IEC60947-2.
The test bench usually consists of the following components:
Control system: including host controller and control panel, used to set test parameters and monitor the test process. Users can set current, time delay and other test parameters through the control panel.
Power supply system: used to provide current and voltage to the circuit breaker for testing. There are usually two options of DC power supply and AC power supply to meet the testing needs of different circuit breakers.
Current measurement system: used to measure the current in a circuit. Precision ammeters or current sensors are usually used for real-time monitoring and recording.
Time delay measurement system: used to measure circuit breaker action time delay. Usually a high-precision timer or timer is used for measurement.
Data acquisition and analysis system: used to record and analyze test data. Test data can be displayed on the screen in real time as needed and can be exported and stored for subsequent analysis and reporting.
Protection safety system: It has over-current, over-voltage, over-temperature and other protection mechanisms to ensure the safety of operators and equipment.
Generally speaking, when using the molded case circuit breaker delay action characteristic test bench for testing, the test parameters, such as current size, time delay, etc., need to be set in accordance with relevant standards. During the test, the test bench will simulate the current changes under actual working conditions and record the circuit breaker's action time delay. By analyzing the test results, it can be evaluated whether the delay action characteristics of the circuit breaker meet the requirements, and can be used for product quality control and engineering design reference.
