CONSTRUCTING DEVICE FOR CONCENTRIC NEUTRAL CONDUCTOR CABLE WITH FUNCTION CHECKING GROUND FLOATING OR DISCONNECTION FROM THE NEUTRAL POINT OF POWER SOURCE AND METHOD THEREOF

摘要

An implementing apparatus for a concentric neutral conductor cable and a ground floating checking method are provided to prevent a voltage imbalance by checking a ground floating or a disconnection from the neutral point of power source in real-time. An implementing apparatus for a concentric neutral conductor cable cuts a connecting line(130) between concentric neutral conductor cables in an active state, while checking a ground floating of the cut concentric neutral conductor cable. First and second connectors(10,15) are connected to a rear portion of the 2-phase concentric neutral conductor cable to be cut. A common connector(20) is connected to a common ground portion. A pair of circuit breakers(30) are arranged in the middle of respective lead lines which are elongated from the first and second connectors. First and second resistor groups(35,40) are parallel-coupled with the circuit breakers on the respective lead lines.
