Claims (1)
これら変流器の二次側に夫々並列接続され対応す
る変流器の二次出力が過電流レベルを越えたとき
に該変流器からの自己電流路をしや断する複数の
熱動形過電流継電器と、前記各変流器の二次出力
電流を加算・整流して１つのトリツプコイルに供
給するダイオード回路とを備えたことを特徴とす
るしや断器の引外し回路。 a plurality of current transformers for detecting phase currents in grid lines;
Multiple thermal types are connected in parallel to the secondary sides of these current transformers and cut off the self-current path from the current transformer when the secondary output of the corresponding current transformer exceeds the overcurrent level. What is claimed is: 1. A tripping circuit for a shield breaker, comprising an overcurrent relay and a diode circuit that adds and rectifies the secondary output currents of the current transformers and supplies the same to one trip coil.
