Equipment use
Small circuit breaker instantaneous operating characteristics test bench. This equipment has a handheld small circuit breaker instantaneous operating characteristics test. It is a device specially used to test the instantaneous operating characteristics of small circuit breakers, that is, it can complete the 3~20In instantaneous current single-pole tripping characteristics test. , in line with the test requirements of national and international standards such as GB10963.1/IEC61009-1. At the same time, the equipment is also suitable for the instantaneous current operating characteristics test of small leakage circuit breakers (RCBO), meeting the test requirements of national standards such as GB16916.1/IEC61008.1, GB16917.1/IEC61009-1. International standard for earth leakage circuit breakers.
The instantaneous operating characteristics test bench of small circuit breaker mainly consists of the following parts:
Power supply system: The test bench is equipped with a stable and reliable power supply system to provide the required power supply voltage and current to ensure the normal operation of the circuit breaker under different circuit conditions.
Fault simulation device: The test bench is equipped with a fault simulation device that can simulate different types of faults, such as overload, short circuit and grounding, to trigger the action of the circuit breaker. The fault simulation device can provide a preset fault current and ensure that the fault is triggered within a set time.
Control system: The test bench is equipped with an advanced control system, which can easily set and adjust test parameters through the instrument panel. The operator can set parameters such as fault current size, fault type and action delay time as needed.
Data recording system: The test bench is equipped with a data recording system to record the operating time, fault current size, triggering time and other parameters of the circuit breaker. This data can be exported and analyzed to evaluate circuit breaker operating performance.
Safety protection measures: In order to ensure the safety of the test process, the test bench is also equipped with a variety of safety protection measures, such as overload protection, short circuit protection and leakage protection, to ensure the safety of operators and equipment during the test.
By using a small circuit breaker instantaneous operating characteristics test bench, the instantaneous operating characteristics of the circuit breaker can be accurately tested and evaluated. This helps to verify the response speed and performance of the circuit breaker when a fault occurs, ensuring that it can cut off the fault current promptly and reliably to protect the normal operation of the electrical system. At the same time, the test bench also provides data recording and analysis functions, allowing for a more comprehensive understanding of the circuit breaker's operating characteristics.
