关键词： power cable   fault location   overview of ranging  

摘要： With the continuous development of social economy and the continuous improvement of the city modernization, people have higher requirements for the reliability of power supply, and the layout of processing lines also requires them to be more standard and beautiful. The power cable is widely used in 110kv and below systems, mainly because it is not easily affected by external factors, has good power supply reliability, does not interfere with radio waves, and occupies a small area. However, because many of the cable lines are relatively hidden, and the testing equipment also has great limitations, it is difficult to quickly determine its failure point after a failure. Therefore, power supply enterprises attach great importance to how to identify the cable fault location, which can improve the efficiency of fault repair and reduce its cost.

摘要： 目前,随着社会的不断发展,电能已经成为人们的生产生活中离不开的关键环节,所以对电网的了解和关注越来越对。发电厂在发完电后,需要通过升压变电站提升电压,然后借助高压输电线路电力送至人们所需的场所,该方式有效的降低了传输过程中的功耗。高压电力送至各用电中心后,降压变电站将降低电力电压,通过配电线路送至各用户终端。随着社会现代化进程的加快,城市电网建设的速度也在不断加快。如今,大城市的大多数配电网都使用电力电缆。因此,分析10kV配电线路电力电缆的故障排除和预防措施是非常必要的。

关键词： power cable   test   research  

摘要： China's power field is developing rapidly, and the development speed of condition based maintenance technology of power equipment is also very fast. Now the research goal of power researchers is to evaluate the operation state of power cables more scientifically and efficiently, and to minimize the damage to cables caused by *** cable condition evaluation technology has not been developed for a long time. When conducting field tests, it is usually combined with the application of condition evaluation and withstand voltage test technology, such as dielectric loss measurement, partial discharge detection and AC withstand voltage test technology, so as to build a relatively perfect power cable test technology system,The core of this system is shock wave test, frequency conversion resonance test and ultra-low frequency test technology. Through such combined application, the weight of equipment can be reduced, the requirements for test power supply are lower, and more effective means can be provided to evaluate the operation state of cable and obtain more accurate data,At the same time, the damage to the cable caused by the test can also be better *** continuous field tests, many cable defects can be detected, which is an important basis for test analysis.

摘要： After entering the modern society, the demand for electricity for production and living is growing rapidly, and the safety and stability of power transmission are becoming more and more important. In this regard, the development and application of power cable equipment fault detection technology has also become an important topic, which plays an important role in cable fault analysis and the implementation of relevant measures. Advanced detection technology has important application value, which can improve the efficiency of cable fault judgment, reduce the adverse effects caused by the fault, and enable the power system to supply power safely and stably.

关键词： 10kV power cable line   design   key points of construction   analysis  

摘要： With the continuous development of social economy, daily life and production of power demand is increasing. 10kV cable as an important part of power transmission plays an irreplaceable role. So far, many cities in China have completed underground cabling of 10kV lines and successfully completed underground inactive track cabling. Under normal circumstances, 10kV cable lines are chaotic, the power supply situation is complex, and there are various forms of safety risks and defects in daily operation. Therefore, only by formulating and implementing effective cable management and maintenance measures, the safety and stability of power system operation can be ensured. Since 10kV cable failures are usually permanent and cause significant losses, it is necessary to improve the management and maintenance of power engineering operations.
