For a constant impedance load or a constant current load, if regulating the secondary voltage by making the changer ratio higher, the primary voltage will get much lower while the load power is restoring, and the power will then lose balance. For a constant power load or a motor load, since the change of OLTC has no or little influence on the load power, the voltage of primary side almost has no change whether the tap operates or not. The influence on the voltage stability with respect to the dynamic restoring load which is sensitive to voltage is also discussed.

对于恒阻抗和恒电流型负荷，在变比上调恢复副边电压的情况下，负荷功率恢复，又使原边电压下降，可使系统功率失去平衡，而对于恒功率负荷和电动机负荷，OLTC的变化不会引起负荷功率的恢复，OLTC的变化对系统电压稳定有利；同时研究了对于一般电压敏感和具有动态恢复特性的负荷，反调分接头对电压稳定性的影响。

The frequency changer Surpasses the voltage fail safe is the frequencychanger middle DC voltage after achieved the degree of hazard adoptsprotective measures, this is a big flaw which the frequency changerdesigns, causes this breakdown reason in the frequency changer actualmovement many, may adopt the measure are also more, when processesthis kind of breakdown must analyze the clear breakdown reason, haspointed takes the corresponding measure to process.

摘 要：摘要变频器过电压故障保护是变频器中间直流电压达到危险程度后采取的保护措施，这是变频器设计上的一大缺陷，在变频器实际运行中引起此故障的原因较多，可以采取的措施也较多，在处理此类故障时要分析清楚故障原因，有针对性的采取相应的措施去处理。关键词变频器电动机整流 Abstract ：The frequenc。。
