Abstract
The invention discloses an online monitoring system for leakage current of a contaminated insulator. The online monitoring system for leakage current of the contaminated insulator comprises a monitoring terminal 1, a communication module 2 and a monitoring center 3, and is characterized in that the monitoring terminal comprises a current sensor 1-1, a humidity sensor 1-2, a temperature sensor 1-3, a power module 1-4 and a control main board 1-5, and is used for detecting the leakage current of the insulator and diagnosing a pollution flashover state; the communication module 2 comprises a network 2-1 and a mobile phone terminal 2-2 and is used for transmitting and receiving monitoring information; and the monitoring center 3 comprises a server 3-1 and a PC terminal 3-2, and is used for receiving, displaying and recording the monitoring information. When the online monitoring system for leakage current of the contaminated insulator is used and pollution flashover early warning of the insulator occurs, early warning information can be automatically displayed on an interface of background monitoring software, meanwhile, the monitoring terminal can transmit the early warning information to a mobile phone of a warning receiving person, and then maintenance personnel can rapidly solve problems. The online monitoring system for leakage current of the contaminated insulator can monitor in real time, and is safe and reliable, and electric power accidents can be avoided to the greatest extent.
