Nader Circuit Breaker

Circuit breaker is a kind of load switch, which has short-circuit and overload protection functions, and its short-circuit protection function is realized by electromagnetic coil. Because of its complete protection function, easy maintenance and use, it is widely used in power systems. This article i...

Whether a circuit breaker can operate effectively and reliably depends to a large extent on the performance and quality of the operating mechanism. Therefore, depending on the circuit breaker, the operating mechanism equipped with it should meet the required nature and reliability, mainly as follows:...

Low-voltage circuit breaker, originally called air circuit breaker. It is mainly used to automatically break the circuit and cut off the power supply when the circuit is overloaded, short-circuited, and undervoltage. A common fault of low-voltage circuit breakers is failure to close. The reasons for ...

In order to correctly judge the status of high-voltage circuit breakers through preventive test data analysis, simple, safe and effective test methods are used to provide a basis for the state maintenance of circuit breakers. The following introduces several commonly used preventive test analysis met...

In our daily electromechanical maintenance, we sometimes encounter the first-level circuit breaker tripping that is supposed to use electrical equipment, but why the upper-level or next-level circuit breaker trips? The following author analyzes the reasons for everyone. The main situation of skipping...
