Abstract

The invention relates to the electric power monitoring technology field and discloses a 3-1000KV cable terminal insulation fault monitoring method. A data acquisition sensor, an aging device host, a data acquisition wireless terminal, a mobile network, a cloud server, a background data management system, an APP management system and a data acquisition transmission optical fiber are included. Faultinformation is timely alarmed or early warned and notified so that first-aid repair personnel can conveniently know an actual condition of a cable terminal in time. Because the cloud server transmitsfault data information to the background data management system and the APP management system, a manager can inquire real-time operation data information of the cable terminal through a computer or acollection APP, and the aged cable terminal can be timely replaced. Real-time on-line cable terminal operation data is achieved, timely early warning is performed on a cable terminal fault, and accidents such as cable breakdown, an interphase short circuit, a grounding fault, an explosion fire disaster and the like caused by aging of the cable terminal are avoided.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a method for monitoring insulation faults of 3-1000KV cable terminals. Background technique [0002] At present, the theoretical value of the service life of 3-1000KV cable plugs and cable terminals is 25 years. In actual use, the aging of the silica gel is accelerated due to the environment and the effect of the electric field. Aging and flashover are likely to cause cable burnout, or electrical burnout, or even explosion, large-scale power outage, fire and other major losses. [0003] Therefore, it is necessary to monitor the cable terminal to determine the real-time status of the cable. The cable terminal cannot be inspected without power failure. At present, there is no real-time online monitoring equipment for cable terminal insulation faults. Real-time online monitoring cannot be performed because of the need for power failure. , it is impossible to give ...
