电力设计方案的综合影响因素探讨与分析.docx

由于电力电缆供电系统有着诸多的优势，比如安全性高、美观性好、可靠性高等，在当今社会不断的进步趋势下，严重缩小了电力电缆的地基范围，但是该系统能够增强功率因数，从而确立起电力电缆在供电体系中的核心位置。由于电缆的敷设方法大概有电缆沟以及穿管等，工作的环境比较繁琐。随着越来越多的城市电缆的建立，出于建立的时间都比较久远，导致电缆的可靠性下降以至于造成故障的发生。但是当地下的电缆出现故障时，能够及时准确的找到故障的位置是极其不容易的，这就会浪费大量的人力物力财力，甚至会出现严重的停电损失问题。在充分分析了电力电缆检测故障的技术之后能够加快查找故障的速度，而且从另一方面能够有利于电力电缆系统的稳定性及安全性的提高。因为一般情况下会将电力电缆埋藏在地下或者隐藏的比较好，从而增加了检测故障点的难度，所以是否能够正确的选择检查故障的设备以及采用的测量手段起到至关重要的作用。此外，包括电缆工作人员在内的大多数人都希望减少停电的时间，而且从该研究领域来讲，在电力电缆的发展方面将起到至关重要的作用。该课题主要将现存的几种常用的电力电缆检测技术进行综合比较，通过对各种不同类型的故障检测，从而得出最为合理的检测方式和手段。同时详细研究了平常用来包庇电线的屏蔽层故障的分析与检测手段，找到其中的原因以及性质问题，从而得出能够精确定位故障点的技术手段，迅速的完成维修工作，使供电系统继续正常工作，从而有利于电网的正常持续工作。关键词:电力电缆 测寻步骤测寻技术Abstract Power cable power supply is safe, reliable, many advantages to beautify the city,along with the rapid development of social production, the power supply cable covers an area of less, the cable capacitance can improve the power factor, the power cable power transmission way occupy the dominant position of power supply. Because the cable generally wear pipe buried underground or into the cable trench laying, complex environment, at the same time with the increase in number of cables and extend the operation time, cable more and more failures. Once the underground power cable fault occurs, quickly detect the exact location of the fault point is more difficult, need to spend a longer time, waste a lot of manpower, material resources, but also cause incalculable loss of outage. Power cable fault detection to improve the processing speed of the cable fault finding technology, plays a decisive role in the power system reliability and stability. Due to the limitations of power cable line invisibility and test conditions make the cable fault finding has certain difficulty, so how to reasonably select the fault test equipment and test method of quickly and accurately find the cable fault shorten outage time is the cable operators are very concerned about the issue, but also has a very important theoretical and practicalsignificance of this researc
