Abstract: The replacement of 500 kV suspension insulators in the power transmission line has problems such as low work efficiency, high labor intensity, inconvenient operation, time-consuming and labor-intensive operation, etc. A work platform device that is easy to carry and easy to operate has been developed. The device adopts light-weight and high-strength materials. The head of the hard ladder is fixedly connected with the cross arm of the work phase, which can withstand external forces of more than 15 kN, and the tail of the hard ladder is reliably connected to the wire. After installing the overhead platform, the operator descends to the operating platform along the hard ladder and works safely. The device can reduce unnecessary adjustment actions when the wire end personnel work, so as to meet the work requirements of safety, comfort and quick replacement, and improve work efficiency.
Key words: transmission line; operating platform; insulator replacement
