Test bench for Instantaneous operating characteristics of Moulded-case circuit breaker
Short Description:
This equipment is used for the instantaneous action characteristic test of the plastic shell circuit breaker, which is completed
10 (12) The characteristic test of Iin unipolar and bipolar series.
Equipment use
The instantaneous operating characteristics test bench of molded case circuit breaker is a device used to test the operating characteristics of molded case circuit breaker under different fault conditions. This equipment is used to test the instantaneous operating characteristics of molded case circuit breakers, completing 10 (12) single-pole and bipolar series I characteristic tests. The equipment complies with the testing requirements of national and international standards such as GB14048.1/IEC60947-1, GB14048.2/IEC60947-2.
It usually consists of the following components:
Control system: The test bench is equipped with a sophisticated control system to control various parameters and operations during the test process. Through the control system, parameters such as fault type, fault current and fault duration can be set.
Power supply system: The test bench is equipped with a stable and reliable power supply to provide the power supply required during the testing process. Power systems often have multiple output voltage and current options to meet the testing needs of different types of circuit breakers.
Switching system: A set of switching systems is installed on the test bench to switch different test circuits and fault conditions. The switching system can simulate various fault types, such as overload, short circuit and ground fault, and provide corresponding test current.
Testing instruments: The test bench is also equipped with some necessary testing instruments, such as voltmeter, ammeter and power meter. These instruments are used to measure and record parameters such as operating time, current characteristics and durability of circuit breakers.
Safety protection measures: In order to ensure the safety of the test process, the test bench is usually equipped with corresponding safety protection measures, such as leakage protection devices, overload protection devices and short-circuit protection devices.
By using the molded case circuit breaker instantaneous operating characteristics test bench, the performance of the circuit breaker in actual use can be accurately evaluated and verified. This helps ensure that the circuit breaker can quickly and reliably cut off the current when a fault occurs, protecting the safe operation of the electrical system.
