Opplei Intelligent lightning protection


The SPD is located in each power distribution cabinet (see the power distribution system diagram for the specific configuration), and it communicates with the data acquisition terminal through the 485 bus. The data collection terminal is set in the adjacent power distribution room, and it is wall-mounted, and the nearest 220VAC is used to collect power. The smart SPD is collected in two ways. The cable specification is RVVSP2*1.0 (signal) + RVVP2*1.5 (power supply), and each channel can be connected at most 16 smart SPDs, and consider reserving, each channel length does not exceed 800 meters. The data collection terminal communicates with the monitoring center via Ethernet. The monitoring center should include: monitoring hosts, server groups, printers, alarm devices, monitoring cabinets, UPS and other equipment intelligent
