Research And Practice Of Strengthening The10kV Transmission Line Icing In Ping Shi Area

This article has carried on the analysis based on the2008Southern ice disaster causes，damage range and return period， at the same time， through in-depth research andinvestigation of Ping Shi area. The study collected data of local， rural network line. Thatsuch as the use of simple methods to improve the value of the ice on the rural network line ofPing Shi area reinforcement， neither science， nor economic.The author aims at the influence of10KV overhead transmission lines of various factorsand the matters needing attention， finishing the analysis， at the same time calculation andSimulation of all aspects of the relevant technology application software. To determine theeffects of various components of10KV overhead transmission line under differentconditions， carefully comparing parameters. Reinforcement is presented below:1，the original line iron crossarm replacement for porcelain cross arm，make full use ofthe characteristics of porcelain cross arm， the weak point tower set Dan in the porcelaincross. To ensure the safe operation of the tower under normal conditions， in excess of designice thickness under the condition of porcelain cross arm fracture， further expand to preventaccidents， ensure the integrity of the tower， is conducive to the rapid repair after theaccident.2， by calculation based on the original line， add new rod， method， shorten the spanof over load by rod section， with fewer cost， effectively reduces the load of tower tower，enhance the ability to resist adverse weather condition.3，the new pole， through calculation and analysis， the use of reasonable depth increasemode， the increase in basic minimal cost， effectively enhanced the stability of tower.Then with plum station10kV show waterline Yangmei Hill branch as an example， iscalculated and simulated by using SLCAD software， the design of strengthening scheme ofthe circuit， and the checking work， and make the investment budget. Ping Shi area of ruralpower grid according to this scheme are strengthened， the scale of investment is not thecase， the establishment of an economic and reliable， can rapidly repair power lines， andpassed the using test.
