Detailed Product Description: | Breaker "rejecting" failure analysis to determine the method is as follows: 1. Check whether caused by low voltage power supply for the trip. 2. Check the trip circuit is intact Xinxiang high-voltage vacuum circuit breakers, if the action is good and the circuit breaker tripped core rejecting, 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, after the operating core does not move, it is likely caused by an electrical fault, "rejecting." Common aspects of electrical and mechanical failures were: · There are electrical reasons: control circuit blown fuse or tripped circuit components such as control switches for each contact, breaker auxiliary contact actuator, anti-hop relay and relay tripping Loop and other bad; tripping circuit break or trip coil burned; relay setting value is incorrect; the DC voltage is too low, less than 80% of rated voltage. · Mechanical reasons are: lack of impact tripping core action, indicating that the core may jam or tripping core loss; contact welding or mechanical jam occurs, the transmission part of the fault (eg pin off, etc.). Breakers "mistaken together" to determine if the breaker failure without automatic closing operation, then it is "wrong fit" fault. General shall be as follows judging process. The inspection confirmed without closing operation. If the handle is in the "post-minute" position of the breaker, but the red light flash Jiaozuo continuous high voltage vacuum circuit breaker, breaker closing Suizhou indicate high voltage vacuum circuit breaker, but it is a "mistake together." You should close the breaker opened by mistake. On the "wrong together" circuit breakers, if the breaker opened again "mistaken together", remove the closing fuses were checking electrical and mechanical aspects of the reason, contact dispatch to overhaul deal breaker switch deactivated. Nanyang high voltage vacuum circuit breaker breaker _ _ Huayi electricity provided by Xian 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! |
