Equipment use
Small circuit breaker delay action characteristics test bench. This equipment is used to test the delay action characteristics of handheld small circuit breakers, that is, 2.55 inches. It is a device specially used to test the delay action characteristics of small circuit breakers. It is mainly used for evaluation. The delayed shutoff performance of a circuit breaker in the event of a fault. The equipment complies with the test requirements of national and international standards such as GB10963.1/IEC61009-1. The equipment is also suitable for the current action characteristics of small leakage circuit breakers (RCBO) during military testing, and complies with GB16916.1/IEC61008-1, GB16917.1/IEC61009 -1 and other national and international standards and relevant leakage circuit breaker test requirements.
The small circuit breaker delay action characteristic test bench usually consists of the following parts:
Control system: The test bench is equipped with an advanced control system, which can set and adjust the test conditions through the operation panel. Operators can select different fault modes, fault current, delay time and other parameters as needed.
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 for testing. The power system has a variety of voltage and current options to meet the testing requirements of different types of circuit breakers.
Fault simulation equipment: The test bench is equipped with fault simulation devices to simulate various fault conditions, such as overload, short circuit and grounding. Fault simulation equipment can provide fault current and delay time that meet the set requirements.
Data recording system: In order to accurately evaluate the operating characteristics of the circuit breaker, the test bench is equipped with a data recording system to record parameters such as circuit breaker operating time, fault current and delayed cut-off time. The data recording system can provide visual data reports to facilitate subsequent data analysis and evaluation.
Safety protection measures: In order to ensure the safe conduct of the test, the test bench is also equipped with a variety of safety protection measures, such as overload protection, temperature protection and short circuit protection. These protective devices ensure the safety of personnel and equipment during testing.
By using a small circuit breaker delay operating characteristic test bench, the delay cutting performance of the circuit breaker can be accurately tested and evaluated. This helps to verify the circuit breaker's operating time and cutting ability when a fault occurs, ensuring that it can cut off the fault current in time, thereby protecting the safe operation of the electrical system.
