Online monitoring system for leakage current of contaminated insulator

[0015] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless specifically stated, can be replaced by other equivalent or equivalent alternative features. That is, unless otherwise stated, each feature is just one example of a series of equivalent or similar features.

[0016] Such as figure 1 The shown on-line monitoring system for leakage current of polluted insulators includes a monitoring terminal 1, a communication module 2 and a monitoring center 3. The characteristic is that the monitoring terminal 1 includes a current sensor 1-1, a humidity sensor 1-2, and a temperature sensor. Sensors 1-3, power modules 1-4 and control boards 1-5 are responsible for detecting the leakage current of the insulators and diagnosing pollution flashover; the communication module 2 includes network 2-1 and mobile phone terminal 2-2, responsible for transmission And receiving monitoring information; the monitoring center 3 includes a server 3-1 and a PC terminal 3-2, which is responsible for receiving, displaying and recording monitoring information.

[0017] The monitoring terminal 1 collects parameters such as leakage current, air humidity and ambient temperature of the insulator in real time, makes intelligent diagnosis results for these parameters, and transmits real-time information of the insulator operation to the monitoring center 3 through the communication module 2. Data transmission between the monitoring terminal and the monitoring center is carried out through three modes of GSM/GPRS/4G. The terminal sends real-time status information such as insulator leakage current, meteorological parameters, and pollution flash warning information, and reports to the background monitoring center through GPRS/4G communication. At the same time, the pollution flashover information is sent to the mobile phone of the police receiving personnel in the form of GSM short message, and the monitoring center can query the real-time monitoring information of the insulator of the monitoring terminal at any time. In addition, through the GSM network, the staff can also send commands to the terminal in the form of short messages through the mobile phone, modify the configuration, and query the status information of the insulator. The PC terminal of the background monitoring center is connected with the database server to store various data in real time. When the insulator has a pollution flashover warning, the background monitoring software interface will automatically display the warning information, and the monitoring terminal will also send the warning information to the mobile phone of the police officer, so that the maintenance staff can quickly deal with the problem.

[0018] The present invention is not limited to the foregoing specific embodiments. The present invention extends to any new feature or any new combination disclosed in this specification, and any new method or process step or any new combination disclosed.
