ABBI/O模件DI811-eADO802-eA变频器高次谐波的危害具体表现在以下几个方面。1、变压器：电流和电压谐波将增加变压器铜损和铁损，结果使变压器温度上升，影响绝缘能力，造成容量裕度减小。谐波还能产生共振及噪声。2=感应电动机：电流和电压谐波同样使电动机铜损和铁损增加，温度升。同时谐波电流会改变电磁转距，产生振动力矩，使电动机发生周期性转速变动，影响输出效率，并发出噪声。3、电力电容器：当高次谐波产生时由于频率增大，电容器阻抗瞬间减小，涌人大量电流，因而导致过热、甚至损坏电容器，还有可能发生共振，产生振动和噪声。4、开关设备：由于谐波电流使开关设备在起动瞬间产生很高的电流变化率，使暂态***峰值电压增大，***绝缘，还会引起开关跳脱、引起误动作。5、保护电器：电流中含有的谐波会产生额外转距，改变电器动作特性，引起误动作，甚至改变其操作特性，或烧毁线圈。6、计量仪表：计量仪表因为谐波会造成感应盘产生额外转距，引起误差，降低精度，甚至烧毁线圈。7、电力电子设备：电力电子设备通常靠***电源零交叉原理或电压波形的形态来控制和操作，若电压有谐波成分时，零交叉移动、波形改变、以致造成许多误动作。除上面所述内容外，变频器的高次谐波还会对电脑、通信、设备电视及音响设备、载波遥控设备等产生干扰，使通信中断，产生杂讯，甚至发生误动作，另外还会对照明设备产生影响。，都将产生因其非线性引起的高次谐波。1SAP250000R0001AX522AABBAdvant1SAP250300R0001AI523AI523B4ABBAdvant1SBP260001R100186AR230ABBAdvant1SBP260010R100107KR5107KR51-U3.6ABBAdvant1SBP260011R100107KR51-P30;07KR51-F12ABBAdvant1SBP260012R100107KT5107KT51-U3.6ABBAdvant1SBP260014R100107KR51-A3.6ABBAdvant1SBP260021R100107CR41-c12ABBAdvant1SBP260100R1001XI16E1-b10XI16E1-E4.0ABBAdvant1SBP260101R1001XO08R1;XOO8R1-B04ABBAdvant1SBP260104R1001XK08F1XK08F1-A3.0ABBAdvant1SBP260105R1001XO16N1-b20XO16N1-C3.0ABBAdvant1SBP260110R1001XC32L1XC32L1-B4.0ABBAdvant1SBP260150R1001TC50ABBAdvant1SBP260512R1001ICMK14F1ICMK14F1-I09ABBAdvant1SVR440621R5200LM012LM012-CXEPM581B1ABBAdvant1SAP240000R0001DI524ABBAdvant1SAP250000R0001AX522AABBAdvant1SAP250300R0001AI523AI523B4ABBAdvant1SBP260001R100186AR230ABBAdvant1SBP260010R100107KR5107KR51-U3.6ABBAdvant1SBP260011R100107KR51-P30;07KR51-F12ABBAdvant1SBP260012R100107KT5107KT51-U3.6ABBAdvant1SBP260014R100107KR51-A3.6ABBAdvant1SBP260021R100107CR41-c12ABBAdvant1SBP260100R1001XI16E1-b10XI16E1-E4.0ABBAdvant1SBP260101R1001XO08R1;XOO8R1-B04ABBAdvant1SBP260104R1001XK08F1XK08F1-A3.0ABBAdvant1SBP260105R1001XO16N1-b20XO16N1-C3.0ABBAdvant1SBP260110R1001XC32L1XC32L1-B4.0ABBAdvant1SBP260150R1001TC50ABBAdvant1SBP260512R1001ICMK14F1ICMK14F1-I09ABBAdvant1SVR440621R5200LM012LM012-CXEPM581B1ABBAdvant1SAP240000R0001DI524ABBAdvant1SAP250000R0001AX522AABBAdvant1SAP250300R0001AI523AI523B4ABBAdvant1SBP260001R100186AR230ABBAdvant1SBP260010R100107KR5107KR51-U3.6ABBAdvant1SBP260011R100107KR51-P30;07KR51-F12ABBAdvant1SBP260012R100107KT5107KT51-U3.6ABBAdvant1SBP260014R100107KR51-A3.6ABBAdvant1SBP260021R100107CR41-c12ABBAdvant1SBP260100R1001XI16E1-b10XI16E1-E4.0ABBAdvant1SBP260101R1001XO08R1;XOO8R1-B04ABBAdvant1SBP260104R1001XK08F1XK08F1-A3.0ABBAdvant1SBP260105R1001XO16N1-b20XO16N1-C3.0ABBAdvant1SBP260110R1001XC32L1XC32L1-B4.0ABBAdvant1SBP260150R1001TC50ABBAdvant1SBP260512R1001ICMK14F1ICMK14F1-I09ABBAdvant1SVR440621R5200LM012LM012-CXEPM581B1ABBAdvant1SAP240000R0001DI524ABBAdvant1SAP250000R0001AX522AABBAdvant1SAP250300R0001AI523AI523B4ABBAdvant1SBP260001R100186AR230ABBAdvant1SBP260010R100107KR5107KR51-U3.6ABBAdvant1SBP260011R100107KR51-P30;07KR51-F12ABBAdvant1SBP260012R100107KT5107KT51-U3.6ABBAdvant1SBP260014R100107KR51-A3.6ABBAdvant1SBP260021R100107CR41-c12ABBAdvant1SBP260100R1001XI16E1-b10XI16E1-E4.0ABBAdvant1SBP260101R1001XO08R1;XOO8R1-B04ABBAdvant1SBP260104R1001XK08F1XK08F1-A3.0ABBAdvant1SBP260105R1001XO16N1-b20XO16N1-C3.0ABBAdvant1SBP260110R1001XC32L1XC32L1-B4.0ABBAdvant1SBP260150R1001TC50ABBAdvant1SBP260512R1001ICMK14F1ICMK14F1-I09ABBAdvant1SVR440621R5200LM012LM012-CXE)
