    Abstract: This paper introduced a multi-power and multi-bus systemic atypical undisturbed fast switching device to promote the safety and stability of the 10 kV power supply system of the aluminum electrolytic enterprise. It compared the undisturbed fast switching device and the traditional standby power switching device and provided the configuration and control principle of the undisturbed fast switching device. The on-load test of the 10 kV power supply system of the aluminum electrolysis enterprise verified the undisturbed fast switching device. Moreover, it recorded the switching actions and analyzed the waveform. Combining the practical switching effects, it shows that the undisturbed fast switching device could improve the stability of the power supply and decrease the frequency of the manual switching operation under emergency conditions and shorten the recovery time.
    Key words: undisturbed fast switching device; 10 kV power supply system; aluminum electrolytic enterprise
