Description
Technical Field
The utility model belongs to the technical field of electric power detection and specifically relates to a distributed monitoring system is put in office is related to.
Background
With the continuous upgrade of urban distribution networks, power cables have gradually replaced overhead lines to become an inevitable trend of future development due to the advantages of small urban space occupation, small influence of severe weather damage and the like. The insulation state of the power cable is directly related to the reliable operation and power supply quality of the urban power transmission and distribution system. If no test equipment is provided, the cable fault point is searched manually, which not only wastes manpower and material resources, but also causes power failure loss which is difficult to measure. How to reasonably select a fault on-line monitoring means, accurately and quickly find the cable fault and shorten the fault power failure time becomes a focus of great concern and deserve discussion and communication for power operation and maintenance personnel. The cable terminal is used as a special insulation structure for recovering the body insulation layer by layer, and belongs to weak links and fault high-speed parts in the operation process of a cable system. According to statistics, more than 70% of power cable operation faults are caused by cable accessory faults under the conditions that external force damage and other factors are not counted. Partial discharge is considered to be an important cause for insulation aging of electrical equipment, and is also used as a common characteristic parameter for insulation state evaluation and defect fault diagnosis, so live detection and online monitoring of insulation partial discharge of a cable terminal are of great significance for reducing cable insulation faults and maintaining safe operation of cables.
