| description | The purpose of the work is to develop the design of a sensor for monitoring the condition of high-voltage power lines suspended insulation. To achieve this goal, a diagnostic criterion was selected, the operating principle and design of the insulation monitoring sensor were determined. As a diagnostic criterion is considered a changing of voltage on the insulator plate due to a change in the distribution of electrical potential on the insulators, caused of damage in the insu-lators string. For the diagnostic system implementation was adopted a sensor based on a capaci-tive divider. The calculations confirm the possibility of registration a damaged element in a insu-lators string by getting of voltage change at the sensors output. The calculation results were veri-fied by modeling in the Multisim software. The parameters of the sensor were calculated, cor-rectness of it is confirmed by the results of laboratory measurements of the new insulators plate capacitances, as well as insulators destroyed as a result of operation. The most important results of the research are the selection of the optimal diagnostic criterion and researching of the pro-posed design sensor effectiveness for assessing the suspended insulation condition. The signifi-cance of the results obtained lies in the fact that the developed design of a sensor allows one to obtain prompt information about the presence of damage in the insulation. The use of the pro-posed sensor design will make possible creation a continuous diagnostic system and identify damage at an early stage, which will ensure timely maintenance. |
