Description

Technical Field

[0002] At present, the fault tripping of transmission lines mainly relies on the voltage, current, circuit breaker position, protection device action information, fault phase, fault distance, etc. provided by the fault recording system for line fault inspection. The existing troubleshooting method is to use the online video monitoring installed on the transmission tower to inspect the line and confirm the fault point, and to use drones for high-altitude inspection and confirmation of the faulty line.

[0003] If the protection action of the transmission line trips and the reclosing fails, the fault patrol can quickly find the fault point. Such faults are generally visible to the naked eye, such as external breakage, wire breakage, foreign objects hanging, insulator breakdown, etc. However, the type of fault that the line trips and recloses successfully is generally an instantaneous fault. The fault patrol is carried out by inverting the corresponding tower interval through fault distance measurement. This type of fault is patrolled and confirmed by existing technical means, which requires relatively high skills of the fault patrol personnel. The discharge point of the size of a grain of rice is not easy to capture and judge, which leads to the expansion of the fault patrol interval and greatly increases the labor intensity of personnel fault patrol.
