Problems solved by technology

[0002] In power distribution lines, due to reasons such as long lines, long branches, and complex structures, when faults such as short circuit, disconnection, power outage, three-phase imbalance, and overload occur, the fault point and cause of the fault cannot be detected in time. Then prolong the maintenance time, cause a large-scale power outage, and cause large economic losses
At present, fault detection is carried out by installing fault detectors in many cable lines. The collected signals of each fault detector are processed by a centralized processor, and the centralized processor is installed on the cable tower nearby through the distribution box. The electric box only stores the battery, and when the battery is used up, it needs to be replaced manually, and the whole box structure is a sealed structure, which has poor heat dissipation effect

Description

technical field [0001] The invention relates to a distribution box for an intelligent on-line monitoring system for cable line faults, belonging to the technical field of line detection. Background technique [0002] In power distribution lines, due to reasons such as long lines, long branches, and complex structures, when faults such as short circuit, disconnection, power outage, three-phase imbalance, and overload occur, the fault point and cause of the fault cannot be detected in time. Then prolong the maintenance time, cause a large-scale power outage, and cause greater economic losses. At present, fault detection is carried out by installing fault detectors in many cable lines. The collected signals of each fault detector are processed by a centralized processor. The electric box only stores the battery, and when the battery runs out, it needs to be replaced manually, and the whole box structure is a sealed structure, so the heat dissipation effect is poor. [0003] I...
