摘要
为解决传统的架空悬链状态方程存在计算繁琐复杂,不利于工程现场计算的缺点,依据架空线路各种应力参数的具体特点,对悬链状态方程进行了推导和合理的近似处理,提出了一种斜抛物线状态方程,最后通过对实际线路的分析、计算和比较,验证了这种方法在计算的精度方面完全符合工程需要,有较好的实用价值。
Abstract：Correct and rapid solution of overhead transmission lines tension state equation is very important to the construction and operation of the lines. In the traditional sense, although e- quation of state of catenariy lines has a precise calculation,it is cumbersome and complex. So, it is not suitable for engineering calculation. On the basis of the tension features of overhead trans- mission lines, this paper put forward a declining parabolic equation,analyzed and calculated actual lines. The result form this study declining parabolic equation has good accuracy and is able to meet the needs of engineering.
