A manual and electric dual-purpose test variable
voltage regulator, including the
voltage regulator box, the fixed plate is arranged in the
voltage regulator box, the fixed plate divides the
voltage regulator box into upper cavity and lower cavity, the self-
coupling variable winding is arranged in the upper cavity, and the lead screw is assembled, the motor is installed in the lower cavity, the motor output shaft is connected with the lead screw through the
gear transmission mechanism, the nut is assembled on the lead screw, the insulating block is fixedly connected on the nut, the first
sliding contact is installed on the insulating block, the first
sliding contact abuts on the self-
coupling variable winding, the input voltage meter, the output
current meter, the output voltage meter and the input
current meter are installed on the
voltage regulator box shell, and the upper and lower ends of the self-
coupling variable winding are connected with the power supply through the first lead line respectively. The utility model is used to solve the problem that the existing
voltage regulator electric device cannot be operated when being damaged.
