Hi friend, are you interested in electric equipment?
Vacuum circuit breaker is the core product in the power protection system.
Our main product is VTZ-12 vacuum circuit breaker. Do you want to know the vacuum circuit breaker test methods? Let me tell you. There are three methods of testing vacuum circuit breaker, including the withstand voltage test, the mechanical characteristic test and the vacuum test.
voltage withstand test
Voltage withstand test is the most important insulation performance in the vacuum circuit breaker.
The purpose is pressure the circuit breaker under the specified voltage to check whether it can withstand the rated voltage without breakdown or flash over. When conducting the voltage withstand test, the test voltage, test time and pressure method need to be strictly controlled to ensure the accuracy of the test results.
mechanical characteristic test
These parameters directly affect the action performance and life of the circuit breaker. In the mechanical characteristic test, it is necessary to use professional test equipment, such as high-speed cameras, displacement sensors, etc., in order to obtain accurate test data. Mechanical characteristic test is mainly used to detect the mechanical properties of vacuum circuit breaker, such as opening and closing speed, contact travel, bounce time and so on.
Vacuum Degree Test
The level of vacuum directly affects the circuit breaker arc extinguishing performance and on-off capability. In the vacuum test, you need to use professional vacuum measurement instruments, such as vacuum gauges, mass spectrometers and so on. At the same time, it is also necessary to disassemble the circuit breaker to observe whether there are foreign objects and metal particles inside it to further confirm the reliability of the vacuum degree.
Vacuum test is an important means of checking whether the internal vacuum of the vacuum circuit breaker meets the requirements.
conclusion
Through the comprehensive using these test methods, the performance of the circuit breaker can be comprehensively tested to ensure the vacuum circuit breaker normal operation. At the same time, it provides good guarantee for the safe operation of the power system.In conclusion, each of the three methods of vacuum circuit breaker testing has the own characteristics and application places
