Operation and Maintenance of Transmission Lines Key words: Transmission line distribution line frequency voltage transmission lines that supply the context, the user plays a vital role in power supply, so the demands on the transmission line is safety first, but also to keep up with economic, because the power company is now a corporate mode of operation, so the requirements in terms of the economy must also be improved, in order to make safe and efficient operation of line, I think that following the transmission network can strengthen and improve in three areas: increased investment in construction projects to improve the operation and increase the level of work breakdown preventive measures. First, the increase in equipment investment areas: 1, to strengthen the structural integrity of transmission lines, increasing line loop or an additional transformer, which had replaced the old transformer energy saving transformer. Increase the transmission power lines, there are some old lines of smaller wire cross section, so that the voltage loss and line losses are large. In the unlikely case of boost, you can replace a large section of wire, or re-installation of the transmission line conductors to increase capacity, while achieving the purpose of reducing line losses. 2, the user at or near the user's installation of substation reactive power compensation equipment. Remain active in the load conditions, improving the load power factor, reduce reactive power load required for Q, will reduce the active power lines and transformers and power loss. As the pace of reactive power compensation device camera, static compensator, power capacitors. Requirements when the available reactive synchronous condenser, reactive power requirement of hours available capacitors, the impact of the load with a static compensator. Placement of reactive compensation equipment location to the actual situation may be. 3, to improve power grid voltage. For example, the power grid was promoted to 6kV 10kV, 35kV electricity network to step-up to 110kV and so on. This method is more obvious for lower power consumption, but investment has increased significantly. When using this method, it should be through the technical and economic comparison. 4, in place of adequate reactive power, the installation could increase the level of operating voltage power network equipment, such as regulating transformers. Because the electricity grid operation, lines and transformers and other electrical equipment, the maximum allowed by the insulation voltage, generally allow no more than 10% of the rated voltage. Therefore, the power grid operation, should try to raise the level of operating voltage to reduce power loss. It must be noted, in the system reactive power supply, used to adjust the transformer tap voltage to improve the way power grids, will load reactive power consumption increases. Second, improved operation and maintenance measures: 1, change the original wiring grid in order to participate in the most favorable way to run wiring. Circuitous routes to improve time, send down, to prevent Kabo Zi and so on. In localities where conditions permit may be closed to the open net net, the radiating power network, at least according to active power loss of the points was obtained by partitioning the network. 2, the full use of generators and reactive power adjustment on the camera's power plants and transformer substations to select the correct tap in order to maximize the level of operating voltage, lower power consumption. 3, in order to improve power supply reliability and meet the needs of the load, usually installed at the new substation with the capacity of two or more transformers in parallel with the model run. When a failure or maintenance, another transformer or the other to maintain power. At light loads, such as the number of parallel operation of the transformer in the same, the winding resistance loss is small, but a larger proportion of core loss. At this juncture, not to overload the transformer part of the case, part of the transformer can be removed, reducing the total loss of the transformer. 4, should be minimized during the maintenance outage of the transmission line flagging numbers, such as the use of line maintenance phase method, charged maintenance, rapid repair method. In this way not only improves the reliability of power supply, but also improve the power grid to run the economy. 5, establish a complete automated control system to calculate the production of electric energy in power plants, electric energy sold to users, as well as electric power plants and substations from the rational organization. 6, try to avoid power loss in distribution network, power grid in the actual operation may be due to poor insulation on electrical equipment while leakage loss. This loss can be maintained by strengthening the power grid to reduce the work. Maintenance work is mainly regular cleaning lines, transformers, circuit breakers and other insulators and insulating sleeve, remove branches touching the wire and take the nest on the line. Third, failure and protection measures 1, in the distribution line, because the lines horizontally, and the smaller distance between the lines, if the same file from the conductor sag is not the same, when the wind is strong swing of the wire is not the same, leading to short-circuit phase conductors caused by collision with each other Therefore, strict control must be in the construction, attention to the tension wire, so that the relaxation phase conductors are equal, and within the prescribed standards. Line inspection, we found that the above problems, it is timely arrangements. 2, wind Guaduan branches falling on the line, or throwing metal objects online wizard will lead to short-circuit phase conductors, or even break. In addition, the high line the bottom of the car or by cable car operation in the lines below, they may cause disconnection or short circuit accident. Therefore, in cross *, across the line should be left a certain interval distance. 3, due to the long wires by water, air and harmful gases, erosion, oxidation damage, steel wires and lightning line most likely to rust, a serious lead in the inspections found corrosion, should be promptly replaced. 4, the line of porcelain insulators due to the impact of harmful components in the air, so porcelain part of the dirty, wet weather encountered, dirty layer to absorb moisture, so that the conductive performance enhancement, not only increasing the power loss, but also likely to cause flashover accident . 5, lines installed wrong or because of failure of the porcelain insulator insulators aging in place under the action of frequency flashover voltage breakdown. Which are found in the inspection of the porcelain insulator flashover traces should be promptly replaced, and the replacement of the new ceramic insulator must withstand test. 6, the ceramic insulation in part by external damage, the occurrence of cracks or damage, wiped out a large piece of porcelain or from the edge of the skirt to the top of both the crack should be replaced, otherwise it will lead to reduced insulation flashover accident occurred. 7, cement rod subjected to external forces shot down collision accidents, such as a car or tractor collision. 8, wire Shouli Bu are so inclined tower, and you should pull tightening or adjustment of pole line. 9, where the vibration in the wire, gold with screw off easily due to vibration of the accident itself, so double-check inspection and cleaning should contact the parts fitting is good. In summary we can see that the management of the transmission lines and equipment to improve many aspects of the work needs to be done, in order for people to spend worry-free high-quality power supply, we must strengthen and improve the quality of learning, so that transmission line safe and efficient operation.
