摘　　要：高压变频器常见的重故障多为单元故障等,而控制电源UPS装置供电异常引起的高压变频器的重故障却不常见,因此在寻找故障原因时也往往被忽略。本文从一个具体案例来分析UPS装置供电异常所引起的高压变频器重故障,为解决故障提供一个参考思路。The common serious faults of high-voltage inverters are mostly unit faults,while the serious faults of highvoltage inverters caused by abnormal power supply of the control power UPS device are not common,so they are often ignored when looking for the cause of the fault.This paper analyzes the heavy fault of the high-voltage inverter caused by the abnormal power supply of the UPS device from a specific case,and provides a referenee idea for solving the fault.

关 键 词：高压变频器 重故障 控制电源 UPS装置
