Process for fastening and assembling open-type zero sequence current transformer by adopting limiting bolts and pressure springs

The invention discloses a process for fastening and assembling an open-type zero-sequence current transformer by adopting a limiting bolt and a pressure spring. The process comprises the following steps: cutting a pouring body of the open-type zero-sequence current transformer to obtain an upper half pouring body and a lower half pouring body; fastening holes are drilled in the seat body on the two sides of the upper half pouring body and the lower half pouring body; a rectangular spring is selected according to the spring pitch, the distance and length of spring wires, the spring rigidity and the spring strength; a limiting bolt sequentially penetrates through the first adjusting block, the rectangular compression spring, the fastening hole of the upper half pouring body, the fastening hole of the lower half pouring body and the second adjusting block to be connected with a fastening nut in a matched mode so that the two pouring bodies can be assembled and fastened. Through the process, the problems of produ
