Deterioration sensing cabinet panel distribution board

摘要

PURPOSE: A distribution board for sensing the deterioration of a live line is provided to simplify an internal structure by sensing a temperature of the live line with a noncontact sensing unit. CONSTITUTION: A deterioration sensing unit(200) senses the deterioration of a live unit(300) by measuring the temperature of a case and senses the temperature change of a connection unit(330) of a circuit breaker(310), a bus bar(320) and a connection unit(323) of the bus bar. The live unit distributes power supplied through a lead-in line to an indoor line. The live line is fixed on a base(120) of the case and includes a main circuit breaker(311), a first bus bar(321), a second bus bar(322), and a sub circuit breaker(312).
