I. Definition and Principle of Vacuum Interrupter
Vacuum Interrupter (VI) is a key switching device used to protect electrical equipment in high voltage power systems. Its main function is to break the current and protect the system from damage when an electrical fault occurs. Unlike traditional oil circuit breakers or gas circuit breakers, the arc extinguishing medium of Vacuum Interrupter is a highly clean vacuum environment, which can more effectively inhibit the generation of electric arcs and enhance the breaking capacity and service life.
The working principle of the Vacuum Interrupter is that when a current overload or short-circuit fault occurs, the contacts inside the circuit breaker will quickly separate, forming an electric arc in the vacuum. As the gas in the vacuum is extremely thin, the arc is extinguished in a short time, thus achieving the effect of rapid disconnection.
2.The advantages of Vacuum Interrupter
Long life and high reliability
Due to the arc extinguishing characteristics of the vacuum environment, the Vacuum Interrupter has a long service life, usually up to 20 years or more, much higher than traditional circuit breakers. And because of the vacuum does not exist in any medium pollution problems, equipment reliability is high.
Smaller Maintenance Requirements
Vacuum Interrupter do not require frequent maintenance and inspection, which makes them less costly to maintain than other types of circuit breakers.
Highly adaptable
Vacuum circuit breakers can work normally in a variety of complex environments, especially suitable for high-voltage power transmission systems and industrial equipment.
3.the application field of Vacuum Interrupter
Vacuum Interrupter is widely used in the protection and control of high-voltage power systems, such as power distribution networks, power plants, substations and so on. They are not only used in the electric power industry, but also play an important role in many fields such as industry, transportation and construction.
