摘要
为了改善电机从变频器切换到电网中存在的不稳定等问题,分析了通用变频器启动方式、技术性能及发展情况,同时分析电机从变频器切换到电网和从电网切换到变频器的过渡过程及可能出现冲击电流的原因,并提出解决方案与措施。该方案在理论与方法上实现了创新,具有很高的工程应用价值。已在工程实际中应用,取得了很好的经济效益。
To the problem of unstability existed in motor switching from inverter to commercial power, the method, function and devel- opment of general inverter are studied. The reason why lashing current is happened when motor switches from inverter to commercial power or when motor is cut from commercial power to inverter is analyzed. An improved method is proposed with new idea in theory and method. The practical application results show that good economic effect is achieved.
