The invention discloses a modular high-voltage test operating table test operating table, and relates to the technical field of electric power capital construction. The modular high-voltage test operating table includes an insulation platform, a front wheel and a rear heel are sequentially arranged on the lower surface of the insulation platform from left to right, one end of the front wheel is movably connected with a steering wheel through a first connecting shaft, a blocking seat is welded to the upper surface of the insulation platform, the upper surface of the insulation platform is sequentially and fixedly connected with a seat, a blocking plate, and a power shell from left to right, and a fixing seat is fixedly connected to one side of the outer wall of the power shell. According tothe modular operating table, the power shell, a mechanical arm, an extensible sleeving rod, a power interface, and an elasticity power line are arranged, the power shell and a high-voltage power supplying battery inside the power shell are used for providing a test power source for a to-be-tested machine body, the work difficulty of testers is reduced greatly, the mechanical arm and the extensible sleeving rod are used, and the effect that the power interface is connected with the to-be-tested machine body in a multi-direction and multi-angle mode is realized.
