| The paper mainly aimed self-supporting tower1lOkV～750kV power transmission line application to study, according to the safety and reliability, advanced technology, environmental protection, Cost saving principle for selecting the tower type commonly used. The common tower type insulation coordination and lightning protection, radial clearance and fittings, tower head electrical size, tower load, structure, optimization, computational application modeling and carry out related technology. Combined with the author’s experience in practical engineering summed up some personal thoughts, the indicators compared tower impact on overall project cost, safety, environment size, from the tower head electrical size, slope, tower body section, the tower diaphragm settings, considering the force transmission line, with open size ground transportation convenience, etc.,were calculated and economic comparison and optimization of existing tower. Through the contrast calculation, optimization scheme is proposed according to the index, and strive to tower finally optimized to meet the perfect and reliable electrical safety and structure as well as the specification requirements of the premise, the technology has the light tower weight and can be applied, while the maximum protection of the environment does not affect the surrounding vegetation and other savings the cost for the power grid construction. |
