Viking 35转速控制器故障原因分析

Investigation on Causes of Malfunction of Viking 35 Speed Controller

以某舰船主推进监控系统为例,对可能导致其Viking 35转速控制器产生无主控电流输出故障的原因进行深入分析。通过搭建试验平台,分别进行高温环境试验、主控输出线路对地试验、主控输出线路短路试验和控制器主板工作机理分析及验证试验,定位故障原因是Viking 35转速控制器的工作电源受到外部干扰。在舰船上采用由隔离电源模块隔离的电源作为转速控制器的工作电源,故障得以消除,该模块的工作边界得以验证。该研究可供后续该类型转速控制器的使用和类似故障的排查参考。

Taking the main propulsion monitoring system of a warship as an example,an in-depth analysis of the possible causes of the failure of the main control current output of the Viking 35 speed controller.A test platform is set up to perform high temperature environment test,main control output line grounding test,main control output line short-circuit test,working mechanism analysis and verification test of the controller main board.The exact cause of the failure is finally identified to be external interference on the working power supply of the controller.Introduction of an isolation power supply module solved the problem perfectly.
