Fault diagnosis device of switch cabinet

Abstract

The invention discloses a fault diagnosis device of a switch cabinet. The fault diagnosis device of the switch cabinet comprises a single-chip microcomputer, a high-speed signal collector, a photoelectric detector, a temperature sensor, a data acquisition module, a fault diagnosis module and a display device. The high-speed signal collector and the photoelectric detector are connected with the single-chip microcomputer and the data acquisition module, the temperature sensor is connected between the photoelectric detector and the data acquisition module, and the data acquisition module is connected with the display device through the fault diagnosis module. Through the above way, the fault diagnosis device of the switch cabinet can real-time monitor the temperature information and running status of the switch cabinet and alarm in time when an exception occurs, avoid the occurrence of the damage and accident of the switch cabinet, meanwhile, it is used for detecting the fault in the switch cabinet and checking the cause of the fault, timely maintenance is carried out by personnel conveniently, safety and reliability are achieved, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of switch cabinets, in particular to a fault diagnosis device for a switch cabinet. Background technique [0002] As a large amount of equipment used in the power grid, the high-voltage switchgear is directly related to the user's power supply. If it breaks down and causes an accident, the economic loss and social loss will be very large. In addition, due to the narrow space inside the switchgear, many parts, complex structure, and small insulation distance, insulation defects are more likely to occur than other equipment, which brings huge hidden dangers to the safe operation of the equipment. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a fault diagnosis device for switchgear, which can monitor the temperature information and operating conditions of the switchgear in real time, alarm in time when an abnormality occurs, avoid damage to the switchgear ...
