What are the functional characteristics of the circuit breaker dynamic characteristic tester?

The circuit breaker characteristic tester is a device used to test and diagnose the performance of circuit breakers in high-voltage power systems. Circuit breakers are common protective devices in the power system, used to isolate faults and maintain equipment. Therefore, it is necessary to ensure their normal operation and timely response. By using a characteristic tester, it is possible to accurately test the various functions of circuit breakers and identify any potential problems or anomalies, in order to take timely measures for repair or replacement. The function of the circuit breaker dynamic characteristic tester is very important. It is mainly used to detect and evaluate the dynamic characteristics of the circuit breaker, to ensure the reliability and safety of the circuit breaker’s performance during opening and closing. It can simulate the characteristics of the power grid, test the action and disconnection characteristics of circuit breakers, and accurately detect and evaluate the operation of circuit breakers.

The main functions of the circuit breaker characteristic tester include the following aspects:

1. Test opening time

The opening time is the completion time of the circuit breaker opening operation, usually expressed in milliseconds or microseconds. This is usually very important because the power system needs to calculate the protection action time and fault distance based on the opening time, and prolonged opening time may have adverse effects on the power system. Therefore, using a characteristic tester to test the opening time can ensure that the circuit breaker responds to faults in a timely manner and effectively protects the power system.

2. Test closing time

The closing time is the completion time of the circuit breaker closing operation, usually expressed in milliseconds or microseconds. Similar to the opening time, the closing time is also very important because it is necessary to ensure that the circuit breaker is closed within the predetermined time to ensure the normal operation of the power system. If the closing time is too long, it may lead to unnecessary shutdown or other losses in the power system.

3. Test contact tripping speed

The contact tripping speed refers to the time required for the distance between the contact points to completely separate from zero when the circuit breaker is opened. This is usually measured by testing instruments and expressed in milliseconds or microseconds. The speed of contact tripping is a major factor causing flicker and arc light, which may have adverse effects on the power system. By using a characteristic tester to test the contact tripping speed, potential foreign objects or wear can be detected and necessary repairs or replacements can be made.

4. Test damping time

Damping time refers to the time it takes for the mechanism to return to its original position (recovery) due to the action of a spring, usually measured by testing instruments and expressed in milliseconds or microseconds. If the damping time is too long, it may cause the circuit breaker to fail in a timely manner, thereby damaging the power system. By using a characteristic tester, it is possible to determine whether the damping time meets the requirements and make adjustments as needed.

5. Test maximum continuous current

The maximum continuous current refers to the maximum current that a circuit breaker can withstand without removing the transmission line. If the circuit breaker cannot withstand the required current, it may damage other equipment in the power system and have a negative impact on safety. By using a characteristic tester, the maximum continuous current of the circuit breaker can be determined and necessary repairs or replacements can be made.

In short, the circuit breaker characteristic tester is a very important tool in the power industry, which can help engineers quickly diagnose and solve problems when faults occur, and ensure the stable operation of the power system. It has the advantages of high precision, high efficiency, and easy operation, which is crucial for the protection and operation of the power system.
