I. Analysis of the Principle of Power System Voltage RegulatorsBefore analyzing the principle of power system voltage regulators, it is necessary to analyze the excitation regulator and draw conclusions through comparison. In practical application, the excitation regulator uses voltage deviation as a feedback quantity for adjustment, thereby keeping the generator terminal voltage within the standard range. However, this type of voltage regulator, especially during grid faults, requires a large a

1. Operating Principle of the DisconnectorThe operating mechanism of the disconnector is connected to the active pole of the disconnector via a connecting tube. When the main shaft of the mechanism rotates 90°, it drives the insulating pillar of the active pole to rotate 90°. The bevel gears inside the base drive the insulating pillar on the other side to rotate in the opposite direction, thereby achieving opening and closing operations. The active pole, through inter-pole linkage tubes, drives
