ける圧縮空気吹付け装置において、空気圧回路を
開閉する電磁弁と電気的に直列に雪センサー回路
を接続することによつて、積雪を感知すると自動
的に圧縮空気をブロアーより吹出して、積雪をそ
の圧縮空気により吹飛ばすことを特徴とする積雪
防止用圧縮空気吹付装置。 In a compressed air blowing device that blows compressed air to the fixed contact part of a disconnector when snow is falling, a snow sensor circuit is electrically connected in series with the solenoid valve that opens and closes the pneumatic circuit, so that it can automatically operate when snow is detected. A compressed air blowing device for preventing snow accumulation, characterized in that compressed air is blown out from a blower to blow away accumulated snow with the compressed air.
