Abschalteinrichtung für Serienstromkreise auf Flugplätzen

摘要

A disconnection device for series circuits (2) including input terminals (3,4) connected to a current source (1), output terminals (5,6) connected to a series circuit (2) and connector elements (7,8) for interconnecting the input and output terminals. An actuator/control is provided for the disconnecter and in a normal position positions the connector elements (7,8) so that each input terminal (3,4) is connected to an output terminal (5,6), and in a servicing or maintenance position the connector elements are positioned so that the input terminals are separated from the output terminals and are connected to an earthing terminal (9) and the output terminals are interconnected and joined to the earthing terminal. In a test position, the connector elements are positioned so that the input terminals are separated from the output terminals and are joined to the earthing terminal (9) and the output terminal are interconnected and are joined to a test terminal (10).
