How Can Intelligent Circuit Breakers Maintain Greater Competitiveness in The Market?
Today, circuit breakers, as a common power distribution management device, are inseparable from most electric fields. Most common circuit breakers in our daily life use thermal bimetals and coils to realize the opening and closing of power lines. Most of them are thermal magnetic circuit breakers, which are one of the more important protection and control components in low-voltage electrical appliances. It integrates with a variety of protection functions. When the line is working normally, it acts as a power switch to connect or disconnect the circuit; when the circuit is short-circuited, overloaded, and leakage occurs, it can automatically trip and cut off the faulty circuit, thereby protecting the circuit and electrical equipment.
With the rise of smart grid, there are higher requirements for supporting power equipment technology, and intelligent circuit breaker is an important part of the power distribution network. However, traditional circuit breakers are mainly realized by the action of thermal double gold and magnetic system. It is more and more difficult to meet the reliability, accuracy and safety requirements of the power distribution system, and it is impossible to realize the communication networking. The function of traditional circuit breakers is too single, and can only provide a certain degree of short-circuit protection, overload protection, and leakage protection functions. Moreover, these three functions are passively triggered, and are not enough to highly protect personal and property safety. For example, when a short circuit occurs, the electrical circuit has caught fire and burned before the short circuit. The leakage protection is also too slow, and the circuit is still open after an electric shock casualty occurs. On the other hand, functions such as data collection, transmission, and remote control cannot be realized, and cannot meet the needs of multi-scenario applications.
The smart circuit breaker can not only improve the reliability of the distribution network, but also make the distribution network safer and more accurate. At the same time, it can also browse the operating parameters of the power grid in real time. When the power grid fails, it can quickly query the fault and eliminate the fault. At the same time, its volume is smaller, which is more convenient to install, saves space, and its modularity can meet the application needs of users in multiple scenarios, and the installation is also easier.
