KOBLINGSANORDNING TIL AUTOMATISK LUKKING AV EN FJERNMATNINGSSLOEYFE I EN FJERNMATNINGSINNRETNING |
摘要 |
A circuit for automatically closing a backup remote feed loop upon interruption of the remote feed loop of a remote feed device for supplying electrical users by means of DC series feed has a holding winding and a response winding disposed in a longitudinal arm of a switching relay, the contact of the switching relay being disposed in a cross-arm in series with a choke coil. The relay operates with a very low voltage drop at the holding winding and occupies a relatively small volume. The circuit can be utilized as an auxiliary relay controlled by means of a delay circuit for selectively cutting in and cutting out the response winding of the relay, particularly in remote feed repeaters or regenerators. |
