Problems solved by technology
The number of power cable samples submitted for inspection due to the issued inspection plan every year is huge and steadily increasing year by year, which makes the storage of power cable samples, query and extraction of sample information in the laboratory too cumbersome, and ultimately leads to laboratory testers. The detection of power cable samples and the collation, summary, analysis and evaluation of test results have brought many difficulties and inconveniences, which seriously hindered work efficiency and work quality

The invention discloses a power cable detection sample information acquisition and monitoring method. The method comprises the following steps: 1, power cable laboratory workers compile unique numbersfor electric power cable detection samples, and the electric power cable detection samples are subjected to dissection, and the image acquisition, detection and storage on the structure of each dissected part can be carried out; 2, the model batches, the production manufacturer information, the image acquisition information and the detection information are input to a power cable detection sampleinformation acquisition library system according to the month period, an electronic information file is established, and the information of the input power cable detection samples are rechecked and stored after the confirmation, and the user exists the power cable detection sample information acquisition library system; 3, information tracing is carried out on products of different cable manufacturers according to the month period, and the needed information is summarized, counted and analyzed. The method has the advantages that the accuracy and the reliability of cargo inspection are improved, and the safety and the high quality of a network power cable are ensured.
Description
technical field [0001] The invention relates to a method for collecting and monitoring information of a power cable detection sample, which belongs to the status control and risk prevention of power distribution cables. Background technique [0002] At present, power grids at all levels (distribution network and main grid) are developing rapidly, and the scale of the power grid is expanding rapidly at an incredible speed. As an important material for power transmission and transformation projects, power cables are used to transmit and distribute electric energy, which contributes to the prosperity and development of the power grid. made an indelible contribution. At the same time, due to its many advantages such as small footprint, high reliability of power supply, less maintenance workload in the later stage of operation and less possibility of electric shock, it is suitable for urban underground power grids, power station lead lines, internal power supply for industrial an...
