Electric comprehensive practical-training equipment

Electric comprehensive practical-training equipment comprises a frame and panels which are inlaid the frame; square steels A and square steels B are spliced into the frame, two end faces of each square steel are provided with side holes, and the other four faces of each square steel are provided with cross through holes which are arranged at the same interval; and each panel is provided with waist-shaped through holes or a socket. The square steels are spliced into the frame of the electric comprehensive practical-training equipment, and the sizes of the frame can be adjusted above standard sizes of 2400mm*800mm*2400mm; and the panels can be installed anywhere inside or outside the frame as needed, and each panel is a steel plate which is equipped with the socket or the waist-shaped through holes having the same size. The electric comprehensive practical-training equipment can simulate electrical engineering construction of buildings, a low-voltage electrical control technology and electrical maintenance of a
