Circuit breakers play an indispensable role in ensuring the reliability of power networks. In order to meet different power system requirements, a variety of circuit breakers are developed, such as CB181F-100. This article discusses the application field and working principle of CB181F-100.

CB181F-100 is an intelligent, digital and multi-function circuit breaker produced by Nantong Rongsheng Electrical Equipment Co., Ltd. It is mainly used in three respects: first, the 35kV single busbar and single busbar system; second, the 660kV high-voltage substation; third, the air insulated switchgear (AIS) of 110kV-550kV DC circuit breaker and ac contactor. Thanks to its many advantages, it can work in extreme temperature, muddy and wet environment, and difficult environment. Furthermore, its current transformers, voltage transformers, core balance current transformers and other protections can meet the requirements of most power systems.

The working principle of CB181F-100 is rather simple. When an overload current or short circuit current occurs, an internal relay or device will detect this current and trip the breaker. The breaker then releases a trip coil, which opens the breaker\'s moving and contacts. This breaks the circuit and isolates the overloaded section of the power system, thus preventing further damage. After the fault is eliminated, the breaker can be manually reset to its original position.

In conclusion, the CB181F-100 circuit breaker is a reliable and efficient device for the protection of power system. It can be used in a variety of systems with high levels of safety and can detect and trip on fault currents. Furthermore, it has a simple working principle which makes it easy to install and maintain. As a highly advanced device, it is widely used in power systems all over the world.
