The invention designs a lightning arrester live-line test trolley which comprises a frame, three mechanical arms of the same structure are arranged on the frame, each mechanical arm comprises a base fixedly installed on the frame, the base is rotatably connected with one end of a first supporting rod, and the other end of the first supporting rod is hinged to one end of a second supporting rod. Anair cylinder is installed at the other end of the second supporting rod, a piston of the air cylinder is connected with the first connecting rod, the first connecting rod is hinged to second connecting rods on the two sides, the second connecting rods on the two sides are hinged to the middles of clamp arms on the two sides respectively, the clamp arms are hinged to a supporting frame, and the supporting frame is fixed to the second supporting rod. The three-phase wiring clamp of the lightning arrester tester is respectively clamped on the three clamp arms on the frame, the trolley drives theclamp arms to be close to the lightning arrester, and controls the clamp arms to stably clamp the lightning arrester counter, thereby ensuring that no contact point disconnection occurs in the measurement process, and improving the stability and safety of operation.
