COMMON TERMINAL BLOCK WITH CURRENT TRANSFORMER, CAPABLE OF MONITORING POWER LINE FAILURES THROUGH NAKED EYES

摘要

PURPOSE: A common terminal block is provided to prevent loss of electric device and supply power in a stable manner by monitoring power line failures through naked eyes. CONSTITUTION: At least one terminal support base(52) made of an insulating material is disposed. Each terminal support base has an upper surface on which at least one conductor bars(54a to 54d) are arranged. Each conductor bar is inserted into a current transformer assembly, and has both terminals screw-coupled to the terminal support base. The current transformer assembly includes a current transformer for performing transform operation on the current flowing along the conductor bar; a light emitting element(62a to 62d) for emitting light while driving current is being input; and a driver circuit for receiving output current from the current transformer and providing the driving current to the light emitting element. The light emitting element and the driver circuit are assembled to a printed circuit board, and the light emitting element is exposed outward such that light emitting operation is recognized through naked eyes. A conductive common connection bar(56) for connecting a pair of conductor bars if necessary, is arranged across over the pair of conductor bars such that common connector bar is screw-fixed to the terminal support base.
