CLAMP-ON FLEXIBLE ROGOWSKI COIL CURRENT TRANSFORMER

摘要

PURPOSE: A divided type Rogoski coil current transformer is provided to accurately measure currents by preventing the measurement limit of the currents flowing in a railroad due to magnetic saturation of an iron core or a direct-current component included in the currents. CONSTITUTION: A Y-shaped coupling part(11) couples a signal wire(24) and a Rogoski coil(23) for transmitting signals. The signal wire is coupled with one side of the Y-shaped coupling part. The Rogoski coil is connected to the signal wire on one side of the Y-shaped coupling part. A coupling groove(17) is fixed to the Y-shaped coupling part. A protrusion portion(22) is formed on the edge of the Rogoski coil.
