Method and device for predicting the service cycle of the splice Russian patent published in 2021 - IPC G01R31/08 

FIELD: power lines.

SUBSTANCE: present group of inventions is a method and device for predicting the service cycle of a splice in a power line in real time for network management for the practical application of cost-effective preventive management. The device and method of the present invention predict the service cycle of the splice by first setting a base time for the splice of a predetermined design based on deviations in the signal curve for the splice near the zero intersection of the signal curve using a sinusoid and the first ratio of the amplitude during monitoring and the amplitude at the beginning and the coefficient of change of the period based on the period during monitoring and the period at the beginning. Such monitoring allows you to build a curve of the rate of destruction, which shows the dependence of time on the rate of destruction. This allows you to determine the percentage of remaining service life and time to failure for a splice during operation, and this failure rate curve can be used to predict the behavior of similar splices to determine when a splice may need to be repaired or replaced, for example in a power line. The device includes probes for determining the instantaneous voltage potential in the splice, a current measuring device for determining the instantaneous output current based on the splice and means for establishing a baseline, monitoring the splice during operation and comparing the baseline level of step (a) with information obtained in step (b) to determine the deterioration in the quality of the splice during operation and the destruction rate curve.

EFFECT: predicting the service cycle of a splice in a power transmission line, analyzing the total TTF time and transmitting a report to a remote central logistics system for control operations.
