The utility model discloses an automatically-tracing liquid resistant speed-governing cabinet for a polar plate, which is applicable to automatic speed-governing control of a motor. A liquid resistor, a polar plate lifting motor circuit, an electrolyte circulating pump circuit and a standby electrolyte circulating pump circuit are connected with a main motor; the polar plate lifting motor circuit is connected with the polar plate of the liquid resistor; a revolution speed transmitter acquires a frequency pulse type revolution speed signal from the main motor; the revolution speed signal is converted into a current type revolution speed signal through a revolution meter on the speed-governing cabinet; the current type revolution speed signal is converted into a current signal through a transducer and transmits analog quantity in a current form and is then input to the module; and a revolution speed signal from a chopper circuit speed-governing is transmitted to the module. The revolution speed signal and a fee
