Embodiment Construction
[0015] Embodiment of frequency converter system
[0016] This embodiment provides a frequency converter system, including a frequency converter and a fan system. The fan system is used to dissipate heat from the frequency converter. Since the frequency converter belongs to the prior art, the protection point of the frequency converter system is the fan system. Moreover, the fan system includes a fan and a fan control device. Since the fan belongs to the prior art, the protection point of the fan system is the fan control device. Therefore, the protection points of the inverter system and the fan system are both the fan control device. Then, the application object of the fan system, that is, the application object of the fan control device is not limited to the inverter. In addition to the inverter, it can also be other of the heat-dissipated equipment.
