Test bench for standard operating characteristics of Moulded-case circuit breaker
Short Description:
This equipment is used for the standard action characteristic test of the plastic case circuit breaker, which is automatic
Complete 1.05ln~1.3In, agreed time action characteristic test.
Equipment use
The molded case circuit breaker standard operating characteristics test bench equipment is used for the molded case circuit breaker standard operating characteristics test. It can fully automatically complete the 1.05ln~1.3In and agreed-upon time operating characteristics test. The equipment complies with the testing requirements of national and international standards such as GB14048.1/IEC60947-1, GB14048.2/IEC60947-2, etc. It mainly includes the following components:
Control system: The test bench is equipped with an advanced control system, which can set and adjust the test conditions of the circuit breaker through the operation panel. The operator can select parameters such as fault type, fault current and fault duration 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. Power systems often have multiple voltage and current options to meet the testing requirements of different types of circuit breakers.
Fault simulation device: The test bench is also equipped with a fault simulation device to simulate different types of fault conditions. It can simulate faults such as overload, short circuit, grounding and overvoltage, and provide the corresponding fault current within a set time.
Recording instruments: In order to accurately evaluate the operating performance of the circuit breaker, the test bench is also equipped with various recording instruments. For example, time recorders, voltmeters, ammeters and power meters are used to record the operating time, operating current and voltage of the circuit breaker.
Safety protection measures: In order to ensure the safe conduct of the test, the test bench is also equipped with safety protection measures. For example, leakage protection devices, overload protection devices and short-circuit protection devices, etc., to ensure the safety of personnel and equipment during the test.
By using the molded case circuit breaker standard operating characteristics test bench, the operating performance of the circuit breaker can be accurately and reliably tested, which helps to verify the operating time and current resistance capability of the circuit breaker under various fault conditions to ensure that it In practical applications, it can cut off the fault current in time and protect the safe operation of the electrical system.
