[0033] Further description will be made below in conjunction with the accompanying drawings.
[0034] see figure 1 , the measurement and communication unit collects the voltage and current signals of the fuse, analyzes and processes them, and sends the analyzed and processed data to the computer in the information center through wireless transmission. Realize on-line monitoring of fuses, can effectively judge fuse failures, and deal with them.
[0035] see figure 2 , the geographical information of each fuse is set in each measurement communication unit, and each measurement and communication unit, the computer in the information center and the GSM communication terminal constitute a fuse fault monitoring and fault judgment system.
[0036] see image 3, a metering PT fuse fault monitoring device, including a power management unit 3, a data measurement unit 1, a central information processor 2, a GSM communication unit 4, a GSM communication terminal 5, a computer 6, and a...
