RESEARCH INTO ACTION OF SURFACE SOIL MOISTENING, DRYING OR FREEZING ON ELECTRICAL CHARACTERISTICS OF GROUNDING DEVICE

The analysis made has shown expediency of modernization rather than reconstruction of earth electrodes, after inspection of long operating substations grounding grids, via building a two-level structure. It will result in both technical and economic effects. The novelty of the results consists in st...

Приведенный анализ показал, что после обследования заземляющих устройств длительно эксплуатируемых подстанций целесообразно проводить не реконструкцию, а модернизацию их заземлителей путем создания двухуровневой конструкции. Это позволяет получить как технический, так и экономический эффект. Новизна результатов состоит в том, что с использованием математической модели исследованы электрические характеристики заземлителя в виде двухуровневой конструкции в зависимости от глубины просыхания или промерзания верхнего слоя земли. Наведений аналіз показав, що після обстеження заземлюючих пристроїв тривало експлуатованих підстанцій доцільно проводити не реконструкцію, а модернізацію їх заземлювачів шляхом створення дворівневої конструкції. Це дозволяє отримати як технічний, так і економічний ефект. Новизна результатів полягає в тому, що з використанням математичної моделі досліджено електричні характеристики заземлювача у вигляді дворівневої конструкції залежно від глибини просихання або промерзання верхнього шару землі.
