The invention discloses a right-angle yoke plate clamp for live exchange of 220 kV strain insulator string. The right-angle yoke plate clamp is detachably connected to one end of an insulation switching pole to connect a right-angle yoke plate, the end, which is used to connect a right-angle yoke plate, of the right-angle yoke plate clamp forms a dual-interlayer structure, thus a right-angle yoke plate can be clamped between the interlayers, and the right-angle yoke plate clamp is fixed on the central position of the right-angle yoke plate. The right-angle yoke plate clamp has the advantages of simple structure, easy installation and operation, reduced maintenance difficulty, improved efficiency, more fastened connection, high strength, good balance, and fewer safety hazards, and can effectively satisfy the safety requirements during the live operation in a narrow base tower, so safe live maintenance is achieved, and the safety and reliability of power network operation are greatly improved.
