Helicopter Patrol The 500-kilovolt Transmission Line Feasibility Study Yang Huai

Based on the current helicopter operation at home and abroad on transmission line and its technical development trend, the paper has carried on research and demonstration on feasibility to apply helicopter in cruising inspection of Yang-Huai 500KV transmission line from various aspects as its significance, necessity, selection of operating management mode and technical working plan as well as its rationalization economically etc.Applying helicopter to operate on power transmission has been tendencyof the world power industry.On using helicopter to cruise, inspect and maintainthe Yang-Huai 500KV transmission line, the first objective is to insist on flyingsafety. Two steps should be taken seperately for short term and long termobjective. First, to rent helicopters and then, to buy them. As for types of thehelicopter,it should be taken into consideration of two facters;i.e. secure andeconomic. At beginning period, we could consider chartering of BO-105Chelicopter and select affiliated equipments and instruments according to thespecific operating projects and methords. By means of helicopter's cruisinginspection on transmission line, it can greatly improve the productivityand has obvious economic benefit.And it will enhance the standard of helicopterapplication in our country, thus promoting the development of general aviationof ourcountry and spuring on the development of related industry as well.
