Hengdian Dongyang City, Kim Dae-magnetic magnet failure and treatment plant --- phenomenon: multi-axis, leakage vehicles, magnetic steel indicator light phenomenon. Reasons: 1) interference and cause. 2) is caused by outdoor rail high current, high-voltage power line near substations, locomotives; cause great interference "prohibit double bow" section, the locomotive commutation. 3) large interfering signals may cause the device locked permanent magnetic materials, the entire column leaking car phenomenon. Find and treatment methods: 1) CANTON or Guanghan Kefeng systems may be appropriate to increase the threshold voltage permanent magnet materials procurement, Jaco The system can adjust the input resistance and resistance threshold. 2) Check the device and the rail side piping magnets embedded within this distance cable insulation is good. 3) Check the device and the inner rail side pipes embedded magnet cable shield is grounded; check if the device itself grounding is good, if the equipment is not properly grounded, but will cause greater interference permanent magnetic material production, temporarily choose grounding, and other ground handling and re-grounded. Hengdian Kim magnet magnetic factory --- if the magnet-related failure analysis arrived at the scene first point of failure that may occur can detect magnets 1) Check whether the magnet over the life; 2) magnet Disconnect the wiring. With magnet detector test magnet performance is good; 3) magnet dimensions are appropriate. Suitable dimensions can make better magnet wheel output signal, shielding more interference 4) bracket is loose; magnet is mounted on the rail reflux. Quzhou permanent magnetic materials, the large magnetic plant, the production of permanent magnetic material is provided by a large magnetic Hengdian gold plant. Quzhou permanent magnetic materials, the large magnetic plant, permanent magnet material production is a large magnetic Hengdian gold plant (www.jjdct.cn) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, contact: gold total.
