Nader Circuit Breaker

High-voltage circuit breakers can cut off or switch on normal working current, or cut off or close short-circuit current. They are important electrical equipment in power systems. It is generally equipped with a special arc extinguishing device to quickly extinguish the arc generated between the movi...

The circuit breaker is a very important switchgear. Its normal operation directly affects the safe operation of the power grid and electrical equipment. Therefore, the operation and maintenance of the circuit breaker must be strengthened to ensure that its performance is intact. In order for the circ...

The floor-standing structure is suitable for low-oil circuit breakers with large rated current and rated breaking current. For example, the outdoor-type low-oil circuit breakers with higher voltage levels mostly adopt floor-standing structures. Figure 1 shows the structure diagram of a floor-standing...

In order to improve its breaking capacity, the oil circuit breaker is equipped with an arc extinguishing chamber made of insulating material around the contacts. The arc extinguishing chamber of the oil circuit breaker uses the gas generated by the decomposition of the oil to form a high-speed airflo...

Circuit breaker (MCB, MCCB, ACB) refers to the ability to close, carry and break the current under normal circuit conditions, and to close, carry and break abnormal circuit conditions (including short circuit) within a specified time Condition) of the current switching device. Circuit breakers can be...
