Variable frequency driving system, frequency converter switching method and device, medium and equipment

The invention belongs to the technical field of variable frequency driving, and particularly relates to a variable frequency driving system, a frequency converter switching method and device, a medium and equipment. According to the frequency converter, the redundant frequency converters are arranged, and the first change-over switch and the switching module are arranged between the two frequency converters, so that when one frequency converter breaks down or is maintained, the other frequency converter can quickly replace the frequency converter to work, the production efficiency can be better guaranteed, and meanwhile, the frequency converters are more convenient to maintain and repair. 本发明创造属于变频驱动的技术领域，具体涉及了一种变频驱动系统、变频器切换方法、装置、介质和设备。本申请通过设置冗余变频器，并且在两个变频器之间设置第一切换开关和切换模块，使得当一个变频器发生故障或者维护时，另一个变频器可以迅速的接替工作，使得能更好的保证了生产效率，同时也使得变频器的维护维修更加的方便。
