Design and research of special work equipment for narrow space in substation

Currently, during the operation and maintenance of the power system, maintenance personnel often use large vehiclemounted lifting and hoisting equipment to work at heights. However, this method has several issues, including expanding the scope of substation outages, high working difficulty, and posing a high risk to personnel and equipment. To address these problems, this paper proposes the design of special mechanical equipment for operating in the narrow spaces of substations. The equipment uses a crawler walking system and remote control operation, which reduces working difficulty, ensures personnel safety, and enables high-efficiency overhauling without extensive power outages.
