双向门机变频调速系统故障处理与分析

Fault treatment and analysis on frequency control system of bidirectional gate machine

针对恰甫其海双向门机变频调速系统故障,介绍了变频调速系统中整流回馈单元故障处理方法,并分析了变频调速系统的工作原理和导致整流回馈单元故障原因,对类似门机采用变频调速系统故障的处理有一定指导作用。

According to the fault of the frequency control system of the bidirectional gate machine in the Qiapuqihai, the paper introduces the fault treatment method of the commutate and feedback to the unit in the frequency control system, and makes analysis on the work mechanism of the frequency control system and the cause of the fault in the comrnutate and feedback to the unit, which gives certain guidance to the fault treatment to the frequency control system of the similar gate machine.
