Technical characteristicsThe collector is directly installed on the insulator and adopts a new type of cut-off ring design. The sampling resistance is added to the sampling circuit to improve the anti-interference ability and ensure the sampling accuracy;
All the components of the product are industrial devices, which ensure the high reliability of the product, and the product design indexes meet the requirements of industrial outdoor products;
Multiple power supply modes:
8.5ah disposable lithium battery;
Lithium iron phosphate rechargeable battery;
Multiple solar panels;
With the function of recording discharge pulse current, it can show the discharge pulse current to the operation and maintenance personnel, and provide detailed original data for fault diagnosis;
The short-distance wireless communication mode is adopted between the pollution collector and the terminal for information exchange, and the cable connection is canceled to avoid the electromagnetic interference caused by too long cable;
The main station system server can receive, store and display the comparison curve between pollution current and ambient temperature and humidity, and the waveform of discharge pulse recorder, etc. to make qualitative and quantitative analysis and trend prediction of pollution current of insulator in operation;
The recording of discharge pulse can record the waveform of 100ms before and after the occurrence of the pulse. The format of the recording file follows the format defined in COMTRADE 1999 standard.
