Foreword
With the rapid growth of China's wind power market and the entry of wind turbine manufacturers, the competitive landscape of China's wind turbine supply market is quietly changing. Wind farm developers are showing unprecedented enthusiasm for investing in and building wind farms, and China's installed wind power capacity will once again exceed expectations and set a new record in the next few years!
The national target for wind power installations in China is 30 million kilowatts by 2020. However, it is conservatively estimated that by 2020, China's installed wind power capacity will reach 80 million kilowatts.
With the large-scale construction of wind farms, wind farm information management systems and wind turbine remote monitoring systems are also widely used. These systems operate in harsh environments, requiring managed wide-temperature industrial Ethernet switches for network support. Therefore, the requirements for industrial Ethernet switches in the Chinese wind power market are becoming increasingly stringent.
Requirements for industrial Ethernet switches in the wind power sector:
1. Wind power applications are in harsh environments with large temperature differences between day and night and severe sandstorms. The required operating temperature is -45 to 75℃, the storage temperature is -45 to 85℃, and the storage humidity is 0% to 95%, with no condensation.
2. The electromagnetic environment of the motor control system is harsh, requiring industrial switches to have strong anti-electromagnetic interference capabilities and a long mean time between failures (MTBF).
3. To ensure communication reliability, a redundant ring network with a short self-healing time is required. In the event of a communication network failure, a smooth switch to the redundant backup line is necessary.
4. To ensure the security of remotely monitored data, the switch needs to have comprehensive network security settings.
Today, industrial Ethernet switches are widely used, especially in the field of industrial security. In the future, their application areas will undoubtedly continue to expand.
