Research On Quick Repairing Of10kV XLPE Cable After Single-phase Fault

As society’s dependence on electricity continues to improve and beautify the needs ofthe urban construction, urban cable rate is rising year by year, along with the cablerunning gradually increase the difficulty. How to quickly repair the cable fault andreducing the cost of repair, become a key issue. Cable Joints material, widely used forthree-phase construction process design and manufacture, how to deal with the middleof the single-phase cable joint insulation, sealing performance to become the newtopic. Cable single-phase fault, cable repair, consider the three-phase insulation of thecable processing, the method is often used to re-create a group (three phase) CableJoints, which not only caused not fault the two-phase unnecessary damage resulting inbroken Road area increases, compensation costs rose the broken road constructiontime, while the cable connector, and an increase in consumption of materials and aseries of problems. Compensation costs of destroying roads with the roadadministration department greatly increased, the cable repair the broken road torecovery occupied the company’s costs. Carried out using the single-phase cablerepair techniques to restore the sealing performance of the work of cable insulation,and can achieve the goal of reducing cable repair costs, speed up cable repair,reducing the difficulty of construction broken road. To this end, this article improvedcable connector technology, cable repair costs and speed up the cable repair speed ofthinking and method.This article on the study10kV power cable joint structure and the constructionprocess on the basis of the impact of cable quality, combined with the cable faultphenomena discussed how to cable one single failure quick fixes. First, it introducedthe current development of domestic and international power cables,10kV powercable concept, structure and application demonstration and analysis. Then, startingfrom the forms and types of cable fault, the cable connector Factors Affecting theQuality and technical control methods, including comparison of the two cableaccessory applications, Failure Analysis of10kV cable connector, and fish bonediagram qualitative analysis of the key factors to affect the quality of cable connector Comprehensive use of the theories and methods presented in this paper a10kV bugfixes to2011when the site operation process as a case study, described the rapidapproach of the single-phase fault in practice, the actual analysis show that themethod effectiveness, contribute to a single cable fault repair to improve quality,promote innovation. Finally, through expert research and feasibility studies and theactual test run effect obtained using the single-phase connector technology to repairsingle-phase fault cable, cable connector construction speed, construction quality,construction costs, achieve "win-win-win" purpose.
