STATE MONITORING DEVICE FOR ELECTRICAL DEVICE

摘要

the present invention, to facilitate attachment or removal for constant monitoring of the attachment state of the temperature and dust from the high-voltage main circuit charging the metal closed type switch gear, the conductor 33 for performing the energization and a core 22 disposed around, and the coil (3) which generates an induced voltage by the electrification of the wound to a portion of the core 22, the conductor 33, for measuring the temperature of the conductor 33 and a temperature sensor 6, for measuring the adhesion amount of the attaching portion dirt and dust sensor 9, the temperature sensor (6) and provided with a transmission unit 42 for external transmission for the measurement result of the dust sensor (9) will. ;
