Abstract

Power cable undertakes the important task of power transmission. In recent years, the use of power cables is increasing, and its safe and reliable operation is very important to ensure the stable operation of distribution system. However, the cable is deeply buried in the ground, so it is difficult to find the problem in time and reliably in ordinary daily inspection. In recent years, the number of cable faults has increased greatly, and the fire failure caused by the explosion of cable intermediate joint accounts for more than 80%. Taking a typical large-scale fire accident of distribution cable as an example, this paper deeply analyzes the prominent problems existing in the installation process of cables and accessories, line protection configuration, operation and maintenance of cable operation environment. The case has high learning value and significant guiding significance. It basically covers the prominent problems in technology, process and management of current distribution cable. Through in-depth analysis of the case, targeted and reliable solutions are proposed, which can effectively improve the operation level of distribution network.
