High voltage vacuum circuit breaker "because after extinguishing medium and arcing contacts dielectric gap is named after the high vacuum, which has a small size, light weight, suitable for frequent operation, no maintenance advantages interrupter in with grid application is more popular. Xi'an Huayi power plant is the high-voltage electrical equipment backbone enterprises, leading products 6-110kV high-voltage vacuum circuit breakers, low voltage switch cabinet, box-type substation, power transformers, voltage and current transformers, high-voltage fuse, load switch, disconnecting switch, zinc oxide surge arresters, harmonic elimination, wall bushing, post insulators, high voltage SF6 circuit breakers, transformers neutral point discharge gap and spare parts, such as circuit breakers "misclassification "Failure to judge and deal breakers automatically trip and protection if not action, and at the time of the trip system has no short circuit or other anomalies, then the circuit breaker" misclassification. "on the" misclassification "of the judge and deal with general points The following three steps. 1, according to the characteristics of the accident phenomenon, that is, before the circuit breaker to trip meter, a signal indicating normal, after a trip in the Yulin indoor vacuum circuit breaker, the green light flashes continuously Xi'an how breaker manufacturer, red light is off, The circuit breaker ammeter and active and reactive power meter indicates zero, you can determine is a "misclassification." 2, check whether they are due to mistakenly touch, misuse, or mechanical vibration force caused by the "misclassification" In this case the cause should be excluded from the switch, immediately sent electricity. 3, if the partial failure because of electrical or mechanical power can not be sent immediately Hanzhong vacuum circuit breaker manufacturers, should contact the scheduling of "misclassification" deal breaker deactivate turn overhaul. Common aspects of electrical and mechanical failures were: electrical faults aspects: protection malfunction or improper setting value, or current, voltage transformer circuit failure; adverse secondary circuit insulation, two DC system grounding occurred, the DC positive, negative power is turned on, which is equivalent to relay action, a signal caused by mechanical faults trip: Trip tripping mechanism untenable; positioning screw to adjust properly, so crank arm three high; trailers spring deformation, Stretch inadequate; wheel damage; trailers slope, errors or wheel in contact with less surface drag shelves Hanzhong vacuum circuit breaker manufacturers, Huayi Electric Power (certified), the circuit breaker is provided by Xian Xian Huayi Huayi power plant. power plant (www.xahy.com) is a leader in Xi'an high-voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Huayi Electric Power leadership with staff warmly welcome all inquiries negotiations to create electricity Huayi a better future.
