The invention relates to an insulation barrier trolley for a high-voltage switch cabinet, which comprises a bottom supporting frame, and is characterized by further comprising a back seat frame which is arranged in a mode of being vertical with the bottom supporting frame, the back seat frame is provided with a cross beam with the height being adjustable, the cross beam is provided with two vertical brackets, each vertical bracket is provided with an isolating insulation barrier which can move in the horizontal direction, and an immovable isolating insulation barrier is arranged between the two vertical brackets; and the bottom supporting frame is provided with a group of universal wheels. The insulation barrier trolley provided by the invention can effectively solve problems of poor reliability and low universality of an existing barrier or barrier trolley, and effectively avoids the risk that an operator gets an electric shock and is injured or died. The insulation barrier trolley is simple in structure, easy to implement and can be widely applied to the field of high-voltage switch cabinet insulation barriers.
