Now every major type vacuum circuit breaker manufacturers have their own models of Anyang high voltage vacuum circuit breakers, and giving it takes is just a code name like it. ZN beginning of the model is the naming rule breaker national standard, and now no one uses generally are made in accordance with their own product-specific. Z represents a vacuum, N denotes indoors, the other numbers and characters no specific meaning. ZN is the beginning of a vacuum households ... beginning ZW is vacuum outdoors ..... V is generally English Vacuum acronym other characters generally have no special significance. -12 Shows such models rated at 12kV. Little relationship between product performance and product models, mainly to see the manufacturer's technical water products. Breaker "misclassification" deal breaker if the fault is not automatic tripping relay action Xinxiang high voltage vacuum circuit breakers, 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 accident phenomenon breaker that tripped the circuit breaker before the meter, a signal indicating normal, after tripping, continuous flash green, red light is off, the circuit breaker ammeter and active and reactive power meter indicates zero Suizhou high-voltage vacuum circuit breakers, 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.
