Binding method for stays inside and outside voltage regulating coil

The invention belongs to the technical field of transformer manufacturing, and relates to a method for binding internal and external stays of a voltage regulating coil of a converter transformer, which comprises the following steps of: manufacturing the internal and external stays and an adjusting filler strip, winding the voltage regulating coil and placing the adjusting filler strip, placing the internal stays on one side close to a central shaft, and binding and fixing the internal stays with a paper tape. The paper tape is fixedly bound in a binding open groove in the middle of the internal supporting strip; the first external supporting strip, the second external supporting strip and the third external supporting strip are arranged in a three-section staggered lap joint mode from top to bottom and placed on the side away from the center shaft, the first external supporting strip, the second external supporting strip and the third external supporting strip are bound and fixed through PET belts, and the fi
