Breaker "misclassification" treatment failures and automatically trip the circuit breaker protection if not action, and in no short circuit tripping system or other anomalies, then the circuit breaker "misclassification." On the "misclassification" of judgment and treatment is generally divided into the following three steps. 1, according to the characteristics of the phenomenon of the accident, which tripped the circuit breaker before the meter, signal indicating normal circuit breakers, high voltage vacuum circuit breaker after tripping Fuzhou, continuous flash green, red light is off, the circuit breaker ammeter and active and reactive power table indicates zero, you can determine is a "misclassification." 2, check whether it is due to mistakenly touch, misuse, or mechanical vibration force caused by the "misclassification", then the cause should be excluded from the switch, power transmission immediately. 3, if the partial failure because of electrical or mechanical power transmission and not immediately, you should contact the dispatcher to "misclassification" deal breaker deactivate turn overhaul. The world's first produced in 1885 in Dongguan breaker high voltage vacuum circuit breaker, which is a combination of a knife and the beginning of the overcurrent trip unit. In 1905, with the freedom of the air circuit breaker tripping device was born. Since 1930, with the invention advances in technology, the principles of discovery and a variety of arc interrupter device, and gradually formed the current institution. The late 1950s, due to the rise of electronic components Nanning high-voltage vacuum circuit breakers, has produced an electronic trip unit, up to now, due to the popularity, there has been the advent of single-chip intelligent breaker. Guangzhou high-voltage vacuum circuit breakers, circuit breakers, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
