Abstract

The invention discloses an intelligent integrated online monitoring system and method for underground cable operation. The online monitoring system comprises a monitoring center as well as a cable anti-stealing detection unit, a cable video monitoring unit, a cable joint temperature monitoring unit, a cable metal sheath grounding current monitoring unit, an environment gas monitoring unit, a cable tunnel water level monitoring unit and a cable tunnel smoke monitoring unit which are connected with the monitoring center respectively. According to the system and the method, various sensors and mutual inductors are adopted to monitor cables and cable environments, the monitoring center masters the operation conditions of the cables in real time and gives an alarm when a normal condition happens, a worker is reminded to clear a fault in time, and large potential safety hazard is avoided; with the adoption of anti-stealing monitoring, the possibility of stealing of the cables is eliminated, in combination of video monitoring, the missing report caused by visual fatigue is prevented, one all-weather dead-zone-free monitoring platform is established, so that visual monitoring of important positions in cable tunnels is realized, manual inspection is replaced, the labor cost is reduced, the time is saved, further, videos can be stored and taken, and later maintenance is facilitated.

Description

technical field [0001] The invention relates to the field of power grid safety monitoring and evaluation, in particular to an intelligent comprehensive online monitoring system and method for underground cable operation. Background technique [0002] In recent years, with the rapid development of power grids, more and more cables are used in urban power grids. With the growing size of cable lines, a serious problem has become increasingly obvious---cable line failure. [0003] On the one hand, the technical capabilities and production levels of cable manufacturers are uneven; on the other hand, due to objective factors such as rising raw material prices and fierce market competition, some manufacturers reduce product quality due to blind pursuit of benefits. The quality of its accessories itself is not stable. At the same time, the cable lines run underground, and the corresponding monitoring and maintenance are relatively difficult. The environment in the cable trench, s...
