Circuit breakers, also known as the air switch, also known as automatic switch, low-voltage circuit breakers. The principle is: when the operating current exceeds the rated current, short-circuit, loss of pressure, etc., automatically cut off the circuit. Currently, the total household switch common with knife switch with porcelain insert Insurance (which has been eliminated) or air switch (with leakage protection MCB). Currently DZ series home use air switch, a common model / specification: C16, C25, C32, C40, C60, C80, C100, C120, and other specifications, where C represents the tripping current, namely the current take-off, such as C32 represents takeoff current of 32A, 6500W heater is usually installed to use the C32 vacuum circuit breaker factory outlets, installation 7500W, 8500W heater use of open space C40. Vacuum with strong insulating properties, in a vacuum circuit breaker, free travel very thin vacuum gas prices high voltage circuit breakers, gas molecules are relatively large high voltage vacuum circuit breaker factory outlets, collide with each other the chance is very small, and therefore, collision free The main factor is not the main reason for the vacuum gap breakdown, and in the high-strength electric field by the electrode deposited metal particle is caused by dielectric breakdown. The size of the vacuum gap in the dielectric strength of the gap not only, the homogeneous electric field of the relevant circuit breaker, and a greater impact properties and the surface condition of the electrode material is acceptable. Vacuum gap in the gap at small distance (2-3 mm) case, there is high pressure air and SF6 gas high insulating properties, which is a vacuum circuit breaker contacts from the general is not the cause of the vacuum circuit breaker price | Guangzhou breaker | Xi'an by the Xi'an high Huayi power plant. Xian Huayi Electric Power Equipment Factory (www.xahy.com) strong, credible, in the Xi'an high-voltage circuit breakers and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi electricity into the brilliant and you work for a better future!
