Cable insulation monitoring devices

The utility model discloses a cable insulation monitoring devices, including leaking current sampling circuit, voltage sampling circuit, current sampling circuit, wireless temperature collection ware,singlechip and LCD, hourglass current sampling circuit voltage sampling circuit current sampling circuit the wireless temperature collection ware with LCD all with the monolithic is electromechanicalto be connected. Beneficial effect: can generate the curve and make things convenient for the staff to evaluate the cable insulation performance, when the safe limit value of settlement appeared surpassing in the cable performance number, the device was reported to the police, and the suggestion staff maintains the cable. Still to influencing cable life factor in the system, detect like cable temperature, system power source, harmonic current etc to remind the staff to handle unusual through the man -machine interface display abnormity item when the appearance is unusual, guarantee cable safety work for more time, slo
