Vacuum with strong insulating properties, in a vacuum circuit breaker, gas is very thin, free travel of the gas molecules is relatively large vacuum circuit breaker factory outlets, collide with each other in a very small chance breaker factory outlets, therefore, not collision free vacuum The main reason for the vacuum gap breakdown high voltage circuit breaker factory direct, and in the high-strength electric field by the electrode deposited metal particle is the major factor in causing dielectric breakdown. The dielectric strength of vacuum gap not only with the size of the gap, the homogeneous electric field, but also to a greater impact properties and the surface condition of the electrode material is acceptable. Under vacuum gap (2-3 mm) in the case of a smaller distance breaker gap, there is high pressure air and SF6 gas high insulating properties, which is a vacuum circuit breaker contacts from the general is not the reason ZN5-10 vacuum circuit breaker three-phase AC 50Hz indoor high voltage circuit breaker, the circuit breaker body and actuator are linked to belong to a whole type of mechanical life increased from 2,000 originally split less oil circuit breaker mechanism to CD10 10000. Advantages whole circuit breaker is to overcome the presence of CD10 original link dead zone, can improve the reliability of the opening, to ensure that equipment and the safety of the grid. ZN5-10 vacuum circuit breaker breaking capacity, suitable for frequent operation and fault more occasions. Welcome to inquire! High voltage vacuum circuit breaker factory direct _ Huayi Electric Power (certified) _ Chengdu, Xian Huayi breaker provided by the power plant.
