Ascending base current transformer test auxiliary device

The invention relates to an ascending flanged base current transformer test auxiliary device which is characterized in that movable sliding blocks are symmetrically arranged on two sides of a horizontal supporting plate, a metal guide rod is coaxially sleeved in an outer supporting rod, a flat-bottom drill bit is arranged at the bottom end of the metal guide rod, and the top end of the metal guide rod is connected with an operation crank through a crank butt joint; the upper part of the metal guide rod is provided with a wiring terminal, and the wiring terminal is connected to a P1 wiring terminal of the CT comprehensive tester through a primary test wiring. The device is scientific and reasonable in design, is researched and developed according to actual conditions in electrical test work of current transformers in ascending flangings of equipment such as transformers and reactors, and has the advantages of simplifying the working process, shortening the working time, ensuring the safety of personnel and equ
