First, the basic working principle of high-voltage vacuum circuit breaker
High-voltage vacuum circuit breaker is a kind of equipment that utilizes vacuum medium for electrical isolation and switching. Its main structure includes circuit breaker body, operating mechanism, contacts, vacuum bottle and other parts. Its basic working principle is to use the insulating properties of the vacuum medium to interrupt or close in the circuit to realize the switching control of electric equipment.
Second, the main role of high-voltage vacuum circuit breaker
1. Safeguard the safe and stable operation of the power system
High-voltage vacuum circuit breaker is widely used in the power system, as an important protection device, which can guarantee the safe and stable operation of the power system. It can automatically cut off the circuit when the circuit fails or exceeds the rated load, avoiding the expansion of the fault, and protecting the safety of equipment and life and property.
2. Realize the remote control of power equipment
With the development of power automation, the high-voltage vacuum circuit breaker can also realize remote control, which improves the operation efficiency and stability of the power system. In the operation of the power system, the circuit load and switch status can be monitored, real-time control of the opening and closing of the circuit breaker to ensure the stability and safety of the power system.
3. Improve the operation reliability of power equipment
High-voltage vacuum circuit breakers have the advantages of simple structure, small size, reliable operation, etc., and can operate stably for a long time in a variety of harsh working environments. The use of high-voltage vacuum circuit breakers can reduce the failure rate of power equipment and improve the operational reliability of power equipment.
Third, the classification of high-voltage vacuum circuit breaker
High-voltage vacuum circuit breakers can be divided into many types according to their different characteristics such as rated voltage, place of use and working mode. The common ones are indoor high voltage vacuum circuit breaker, outdoor high voltage vacuum circuit breaker, SF6 gas circuit breaker and so on. Different types of high-voltage vacuum circuit breakers play different roles in different occasions.
Conclusion
In short, high-voltage vacuum circuit breaker is an indispensable and important device in the power system, and its function and role are not only closely related to the safe and stable operation of power, but also of great significance for the enhancement and development of modern power system.
