The advantages of our vacuum circuit breakers
Vacuum circuit breakers provide reliable protection and excellent performance for power systems. They have excellent arc extinguishing ability and long service life, making them an ideal choice for high voltage and high current applications. A deep understanding of its functions helps ensure the efficient operation and long-term safety of electrical systems.
Arc extinguishing performance
Vacuum circuit breakers use vacuum as an arc extinguishing medium, which can quickly extinguish the arc and avoid contact burnout. This characteristic ensures that the circuit breaker can still operate efficiently and stably in high voltage and high current environments.
Long service life
Due to the reduced wear and oxidation of contacts in the vacuum environment, the mechanical and electrical lifespan of vacuum circuit breakers is generally long, with low maintenance frequency, which can save users long-term operating costs.
High security
Vacuum circuit breakers do not produce harmful gases or pose explosive hazards during the breaking process, and their overall safety performance is much higher than traditional circuit breakers, providing more reliable protection for the power system.
Environment protection
Unlike circuit breakers that use sulfur hexafluoride (SF ₆) gas, vacuum circuit breakers do not emit greenhouse gases, are green and environmentally friendly, and are in line with the current trend of sustainable development.
Wide range of applications
Vacuum circuit breakers are suitable for multiple fields such as power, metallurgy, petrochemicals, and manufacturing, and can meet various application needs from distribution cabinets to substations. They have strong adaptability and practicality.
Intelligent upgrade
Modern vacuum circuit breakers can be combined with intelligent monitoring and protection devices to achieve remote monitoring, status diagnosis, and preventive maintenance, helping users achieve efficient management and intelligent upgrading of power systems.
