The distribution automation communication network is to build a "communication highway" between the distribution equipment and the distribution automation main station system, and completes the four remote functions of "telemetry, remote signaling, remote control, remote adjustment". The distribution automation network will mainly realize two-way distribution automation data transmission:
1. Upload monitoring data: upload the monitoring data of various monitoring equipment installed in power grid facilities such as ring network cabinets, switchg2020-05-29ears, pole switches, etc. to the sub-station or main station in time and accurately;
2. Releasing the setting data: the setting data of the sub-station or the main station can be accurately and timely delivered to various monitoring equipment installed in power facilities such as ring network cabinets, switchgear, and pole switches.
With the development of computer technology, modern network communication technology, and automatic control technology, distribution network automation technology has also developed. Based on PoE Switch, customers can quickly build a reliable, efficient, and flexible distribution network. Based on a high-reliability and high-security communication network, it supports flexible and adaptive fault handling and self-healing functions to meet the requirements of future distribution system integration, self-healing, compatibility, and optimization.
PoE Switch for Ethernet terminals
Industrial PoE Switch application advantages in distribution automation:
1. PoE Switch for Ethernet terminals of Ethernet terminals can adapt to the harsh outdoor environment, IP40 protection level, dustproof, moistureproof, anticorrosive, high-temperature difference -40 ℃ to 75 ℃. Fanless heat dissipation design of aluminum profile improves equipment stability.
2. The industrial switch works reliably and stably in the harsh electromagnetic environment: through industrial four-level electromagnetic compatibility testing, it has high protection performance in data port lightning protection, anti-fast pulse group, anti-static and other aspects, which can effectively prevent industrial interference: High-voltage AC electric field, electrostatic field, arc, thyristor, etc .; defense against natural interference: lightning strikes, various electrostatic discharges, magnetic storms, etc .;
3. Instant ring network self-healing: support ring network redundancy technology, improve the security, reliability, stability of the network, and ensure the undisturbed switching of network communication, the switching time is less than 20ms (network self-healing time)
4. Realize the backbone Gigabit self-healing ring network and support the backbone 100M self-healing ring network.
5. Dual power redundant design, DC9-36V, to ensure power supply safety.
6. Long-distance fiber transmission to meet a wide range of communication coverage.
7. The equipment has an average trouble-free operation of 100,000 hours and free five-year after-sales guarantee.
8. Convenient WEB interface configuration and management.
