Abstract
The invention belongs to a kind of 110 kilovolts of power transmission sequence single-pillar towers and establish the lightning protection method of installation of dual lightning wires.It is characterized in that fixing the lightning conducter cross-arm 3 of respective length at ground connection place, single-column shaft tower 1 upper end 2, lightning conducter 4 is set up at two ends at this cross-arm respectively, the installation site of other cross-arm, lead, insulator string etc. still is the invariant position that 110 KV single-pillar towers are established single lightning conducter.
Description
The invention belongs to a kind of 110 kilovolts of methods that the power transmission sequence single-pillar towers is established installation of dual lightning wires.
At present, the lightning protection method of 110 kilovolts of power transmission sequences is mainly taked following 2 kinds of methods: 1) single-pillar towers is established single lightning conducter; 2) door type twin columns tower erection installation of dual lightning wires.The 1st kind of method so lightning fault often takes place, influences safe power supply because lightning protection properties is lower in actual motion.Though the 2nd kind of method lightning protection effect is better, but because the quantity of 110 kilovolt in electrical network is more and divide cloth cover wider, so, if all adopt the lightning protection of door type twin columns tower erection installation of dual lightning wires, then the investment of Zeng Jiaing is more, is difficult under existing conditions to realize.
For improving the lightning protection properties of existing 110 kilovolt, improve the power supply reliability of electrical network, the purpose of this invention is to provide the lightning protection method that a kind of 110 KV single-pillar towers are established installation of dual lightning wires.This method is established single lightning conducter method than single-pillar towers, and lightning withstand level improves 14%, and shielding lead rate reduces 80%, hits the bar rate and reduces 35%, and trip-out rate reduces 40%, and lightning protection properties significantly improves; Than the method for door type twin columns tower erection installation of dual lightning wires, lightning protection properties is identical, but per 100 km can be reduced investment outlay about 450,000 yuan.
The not only newly-built line project of the present invention can adopt, and can be used to transform the circuit of just establishing single lightning conducter at operating 110 kilovolts of single-pillar towers.Use the present invention, small investment, it is remarkable to improve lightning protection effect.
The formation of invention: fix the lightning conducter cross-arm 3 of respective length at ground connection place, 110 kilovolt single-column shaft towers, 1 upper end 2, set up lightning conducter 4 respectively at the two ends of this cross-arm then.The invariant position of other cross-arm, lead, insulator string etc.
With reference to the accompanying drawings enforcement of the present invention is further described below.
Fig. 1 is the schematic diagram that 110 KV single-pillar towers are established installation of dual lightning wires.
According to shown in Figure 1, the lightning conducter cross-arm 3 in that respective length is fixed at the upper end of 110 kilovolt single-column shaft towers 1 ground connection place 2 sets up lightning conducter 4 respectively at the two ends of this cross-arm then.The invariant position of other cross-arm, lead, insulator string etc.About the strength problem of single-column shaft tower, can solve according to different meteorological conditions, the different conductor trade mark, different spans.Can adopt corresponding reinforcement measure to special circumstances.
