Arrangement for preventing the formation of a foreign layer on a high-voltage insulator

Abstract

An arrangement for preventing the formation of a layer of foreign material on a high-voltage insulator. In situations where wind and rain are not available to clean a high-voltage insulator and thereby prevent arcing, this invention provides blowers which move a stream of air around the insulator. The blowers may be provided with motors which are supplied electrical energy from local low-voltage networks, or from a plurality of solar cells which are disposed on grounded parts of the support structure of the power line network. In some embodiments, the blowers may be of a motorless type and mounted directly on a high-voltage carrying conductor. In such a motorless blower arrangement, the blower blade is configured so as to have points which generate and repel ions in accordance with the known point-effect principle.
