CABLE CONNECT BOX AND HINDRANCE DETECT METHOD OF ELECTRIC CABLE

摘要

PURPOSE: A cable connect box and a hindrance detect method of an electric cable are provided to check a disconnecting of a power cable by measuring an insulating resistance of the power cable. CONSTITUTION: An outdoor cable connection box including a disconnector includes a main body(11), a disconnector(20), and an operating bar(24). The disconnector(20) is installed in the inside of the main body(11). The disconnector(20) includes an input terminal(21), an output terminal(22), and a lever(23). The operating bar(24) is connected to the lever(23) of the disconnector(20) in order to turn on or off the electric power. A plurality of outdoor cable connection boxes(10) are installed between high-voltage distributing lines. A disconnecting state of a power cable(3) is checked by measuring an insulating resistance of the power cable(3).
