【摘要】 从直接高-高型变频调速系统的概念,引入高压变频器在这种特殊调速系统中的重要性。报告了由于"非线性"和"自举"等是高压变频器产生污染供电系统的现状,提出了抗干扰的必然性。进行实际中高压变频器的特殊干扰包括供电电源对变频器的干扰、变频器本身的干扰以及变频器对电动机的干扰等的调查及全面的分析,通过列举实践的典型现象,并有针对性进行了现象分析。总结了在实际的直接高-高型变频调速系统的设计、安装与应用中的特殊干扰,结合生产实际提出了相应的解决方法和对策。更多还原

【Abstract】 From the concept of direct high-high type frequency control system, introduce the importance of high-voltage in this particular speed control system. Report that "nonlinear" and "bootstrap" is the status situation of that high voltage inverter produces pollution, inevitability of antiinterference, it analyses actual interference of high voltage inverter including the interference from power supply, itself and inteference on the motor through typical phenomenon, summarizes the design, installation and special interference in application of actural direct high-high type frequency control system and puts forward corresponding solutions and countermeasures combined with the actual production.更多还原
