Nader Circuit Breaker

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...

The oil in the oil-rich circuit breaker and the oil-less circuit breaker have the same function (both transformer oil), which is mainly used for insulation and arc extinguishing. If it is mainly used for insulation and heat dissipation in the transformer. Both oil-rich and oil-less circuit breakers m...
