Abstract

複数の針状電極を円環状に構成し汚れ防止機能を有した静電塗装装置において、任意の針状電極がアース体に近接した場合に、スパーク放電の発生を確実に防止し、かつ、その他の針状電極において、形成した静電界の強度を適正に維持する。 塗装ガン（５）は、円環状のベース部材（２）から半径方向外側に向けて略等間隔の放射状に複数の針状電極（３（３ａ～３ｊ））が突設されるリング状の電極部（４）と、電極部（４）に高電圧を印加する高電圧発生器（６）と、を含む汚れ防止装置（１）を備える。針状電極（３）は、個別抵抗器（９（９ａ～９ｊ））、ブロック別抵抗器（１０（１０ａ～１０ｅ））、および内蔵抵抗器（１１（１１ａ～１１ｊ））を介して高電圧発生器（６）に並列的に接続される。
