Zero carbon park grid connected power quality monitoring device

Zero carbon park grid connected power quality monitoring deviceAdopting a dual ARM core processor based on Xilinx SoC architecture, ARM1 runs embedded Linux, TCP/IP protocol, HTTP protocol, web server, storage, statistics, and analysis of power quality data, while ARM2 is used for data sampling and power quality data calculation. The device samples up to 1024 points per cycle and has high measurement accuracy to accurately record fault waveforms. Using a 32GB industrial grade large capacity SD card, it can store event records, fault waveforms, and other data for a long time. Featuring a user-friendly interface, the 800 * 480 pixel dot matrix color large-sized LCD allows users to view real-time waveforms and fault waveforms on-site, facilitating fault analysis.

2 Naming and selection of device models

3 Hole size and installation method

The device adopts embedded installation. First, make a hole on the cabinet (screen) panel as shown in 3.1, and then place the device into the hole as shown in Figure 3.2 until the device panel is against the cabinet (screen) panel. Reinstall the fixed bracket and screw the screws into the screw holes to securely fasten the device to the cabinet (screen).

Zero carbon park grid connected power quality monitoring devicePrecautions for use:

1. Before use, the instrument needs to be powered on for 15 minutes.
2. Be careful to prevent vibration and impact, and do not use in places with excessive dust and harmful gases.
3. The input wire should not be too long. If the input end of the measured signal is too long, please use twisted pair shielded wire.
4. If the signal is accompanied by high-frequency interference, a low-frequency filter should be used in the line.
5. When stored unused for a long time, please power on for at least 4 hours every three months.
6. Long term storage should avoid direct sunlight and should be stored at an ambient temperature of -25 ° C~55 ° C.
7. If the instrument does not display, the auxiliary power supply should be checked first to ensure that the voltage is within the range.
8. If the display is abnormal, check if the input signal is normal and if the signal terminals are tightened.
9. Unless the PT has sufficient power, the PT signal cannot be used as an auxiliary power source to ensure the normal operation of the instrument.
10. The screws of the current connection terminals in the CT circuit must be tightened to ensure reliable contact between the incoming and outgoing lines, in order to avoid faults.
11. To calibrate instruments, the calibration instrument should be better than level 0.1 to ensure calibration accuracy.
