| Summary: | Insulator, electrical device designed for electrical isolation and mechanical fastening
of electrical installations or their separate parts, which are under different electrical
potentials. As an element of the power system, it plays an important role in
ensuring its reliable operation. At present the issue of diagnostics and monitoring of
insulators is still topical. The article provides statistical data of failures on overhead
lines and lists methods and devices for detecting insulation damage. The research
problem is the lack of a reliable and cost-effective device for early detection of
insulator failure under voltage. The solution is the previously proposed method
of diagnosing single-element insulators by temperature. The author proposed a
scheme of the diagnostic device, described its principle of operation in normal and
emergency modes. The diagnostic device made according to the proposed scheme
is simple, works under voltage and without the intervention of operating personnel. |
