METHOD FOR <tab>GAS SUPPLY TO HIGH VOLTAGE STRUCTURES OF HIGH-VOLTAGE INSTALLATIONS

摘要

A method for provision of gaseous nitrogen of high voltage structure of high-voltage installation comprises preparing dielectric inert gas mixture and supplying gas mixture to working a high-voltage installation. Before starting and at the end of work the operating installation and pipes are blown with dry nitrogen,worked out nitrogen is carried off, dry clear nitrogen is supplied to the high-voltage installation.
