Embodiment Construction

[0016] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

[0017] The cables running on site are basically drawn out from the substation, so this embodiment is installed in the substation.

[0018] This embodiment is connected to the SCADA system (data acquisition and monitoring system) as a substation in the SCADA system (see Figure 3).

[0019] The SCADA system realizes "remote control, remote measurement, remote adjustment, and remote signaling" of the power grid, and has been widely deployed in power grids of various voltage levels, especially for power grids above 35kV.

[0020] As shown in Figure 1, the present embodim...

Abstract

A kind of electric cable insulated state monitor and use life manage system in electric technology field, it includes: data collection module, data analysis module, data-base module, image display module and report manage module, the data collection module takes charge to collect the cable insulated monitor data, and sends the monitor module to the data analysis module and image display module, save the monitor data in data-base module at the same time; the data analysis module pre-processes and analyzes the cable insulated monitor data after receiving them, judges the insulation and residual life of cable by combining with the related data, saves the judge result in data-base module and sends it to the image display module; the data-base module memory the monitor data and judge result; the image display module display electric net image and monitor data; the report manage module read the monitor data and judge result saved in the data-base module. This invention analyzes data largely, the covered information is abundant, it advanced the judge precision and effect.

Description

technical field [0001] The invention relates to a system in the field of electric power technology, in particular to a power cable insulation state monitoring and life management system. Background technique [0002] The cables used by industry and enterprise departments (especially for power supply to important loads) will age after running for a period of time, leaving hidden dangers of accidents. If measures are not taken in time, it may cause major property and other losses. The off-line detection of cables is often not feasible for cables in operation. Therefore, on-line monitoring technology of cables and the judgment of the operating status of cables are necessary, so as to facilitate maintenance or even replacement of cables at an appropriate time. The key technologies of cable condition monitoring and life management include two aspects: data acquisition and data analysis. Due to the relatively small leakage current of the cable and the interference on site, the da...
