Detailed Product Description: | "High-voltage vacuum circuit breaker characteristics: ① contact opening distance small, 10KV vacuum circuit breaker contact opening distance is only about 10mm, operating power operating mechanism is small, small mechanical part of the trip, its mechanical life is long ② arcing time. short, and has nothing to do with the current size of the breaker switch, generally only half cycle after the contact gap ③ extinguishing media recovery faster, better off breaking performance near fault zone. ④ due to dredge at the breaking current small amount of wear So long electrical life of contacts, breaking up the full capacity of 30-50 times the rated current breaking more than 5000 times in Changsha high-voltage vacuum circuit breakers, low noise suitable for frequent operation. ⑤ small size and light weight. ⑥ apply Breaking capacitive load current of the circuit breaker "rejecting" failure analysis to determine the method is as follows: 1. Check whether the voltage is too low due to the power of 2 trip, check the trip circuit is intact, if the trip is good and the core action. rejecting breaker, then a mechanical failure. 3, if the power supply is good, if the core action and weak, the core jam or malfunction caused by rejecting the coil may be faulty electrical and mechanical aspects simultaneously. 4, if the operating voltage is normal Ganzhou voltage vacuum circuit breaker, after the operating core fixed Yiyang voltage vacuum circuit breaker, it is likely caused by an electrical fault, "rejecting" the common faults of electrical and mechanical aspects were: · There are electrical reasons: control circuit fuse Each device fuse or tripped circuit components such as control switch contacts, circuit breakers auxiliary contact actuator, anti-hop relay and trip circuit protection and other bad; tripping circuit break or trip coil burned; relay setpoint incorrect; the DC voltage is too low, less than 80% of rated voltage · mechanical reasons are: lack of impact Trip core action, indicating that the core may jam or trip off the core; welding or mechanical contact occurs card astringent, transmission failure (such as a pin off, etc.). Yiyang voltage vacuum circuit breaker, Huayi Electric Power (certified), the circuit breaker is provided by Xian Huayi power plant. Xian Huayi 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 the staff warmly welcome all inquiries negotiations, to create a better future Huayi electricity. |
