碳纤维复合芯导线综合性能的试验研究
摘要
近年来我国电力系统迅猛发展,架空导线输送容量出现严重不足的现象,各国供电公司都在积极寻找应对的方案。方案中最佳的选择是寻找一种合适的扩容导线,最好不改变原有输电走廊。碳纤维复合芯导线即是这种最佳选择。然而针对碳纤维复合芯导线挂网运行的试验及检测都不系统。
按国家标准的检测程序建立一个碳纤维复合芯导线的试验平台,试验平台主要由检测设备构成,并且针对碳纤维复合芯导线的试验对设计的拉力机,升流器,过滑轮,微风振动系统,电阻率测定仪,直流电阻测定仪等提出更为合理的参数,确保整个试验与检测的顺利进行。
对碳纤维复合芯导线的高温拉断力,高温握力,温度与弧垂,耐振疲劳等机械性能进行试验,并由此得出碳纤维复合芯导线弧垂低,抗覆冰性能良好等关键性能优于现挂网运行的钢芯铝绞线的指标,碳纤维复合芯导线的施工以及挂网运行需要注意的铝股变形和过滑轮折断等问题,对导线寿命预测等提供一个新的标准。
对导线进行直流电阻的检测,铝股电阻率的测定,导线载流量和电晕与无线电干扰等电气性能分别进行试验,得出了碳纤维复合芯导线优于钢芯铝绞线的扩容作用,高温运行下扩容将近一倍,另外碳纤维复合芯导线的起晕电压也较高,易于高压高温下运行,无线电的电压也较小。最终也为碳纤维复合芯导线挂网运行提供较为准确的数据支持。
In recent years China's electric power systems developed rapidly, the phenomenon of transmission capacity of overhead conductors is serious deficiencies, the power company of all the countries are actively looking for the response programs. The best choice of programs is to find a suitable expansion of wire, preferably without changing the transmission corridor. ACCC is the best choice for this. However, the test and inspection for ACCC hanging on to run are not systems.
To establish a test platform for test a ACCC according to national standards. The test platform is mainly made up of testing equipment. The system include the Tensile testing machine, High-current generator, over pulleys, Aeolian vibration system, electrical resistance instrument, etc. the DC These machines are more reasonable than before because of designing carefully.
The ACCC is many good mechanical properties. The tensile force at high temperature, the grip at high temperature, the relationship between sag and temperature , the perform at vibration etc. We can conclude lots of better performance after the test. In addition, we can expect more accurately the life of ACCC by the test results.
The ACCC is lots of good electrical performances. These are the test of DC resistance, the test of an aluminum resistivity, and the capacity of current of an ACCC, the occurrence of the corona at high voltage and other electrical performances. So, we can prove that the ACCC have better performances at high temperature and high voltage. The current capacity of ACCC is double the general ASCR under normal running. We can also conclude that the ACCC have a higher occurrence voltage for corona and a lower radio induced voltage. In all, The test is the basis of the ACCC running in general grid.
