Industrial Ethernet Switches Application of The Power Industry

In modern industry, special industrial Ethernet switches are usually used to define different Ethernet frame priorities, so that the information needed can be transmitted at the fastest speed. Industrial Switches are widely used because of their various characteristics, especially in the harsh industrial environment, industrial switches with excellent performance are preferred.

Industrial switches are widely used in intelligent transportation, security monitoring, wind power photovoltaic, coal mining and other fields. In particular, power, transportation and metallurgy are known as the three potential industries for the application of industrial switches. Today, we mainly talk about how industrial ethernet switches are applied to the power industry. The power industry is the most important application field of industrial switches. As the industry continues to change to the direction of intelligent, efficient, reliable and green development, the corresponding investment continues to increase. The construction of smart grid and the continued implementation of policies such as "increasing the size of the power supply and suppressing the small" have led to the growth of the market scale of industrial switches in the industry.

When industrial switches are used in the power industry, they will be concentrated in three fields, including thermal power plants, wind power generation and power grid construction.

In large-scale thermal power plants, with the increase of power equipment and the complexity of automation process, the requirements for data acquisition and monitoring of auxiliary control equipment are becoming increasingly strict. The auxiliary production workshops of large-scale thermal power plants are composed of water network, coal network and ash network. Each network can become an independent system, and each control point is relatively scattered, such as the treatment of water, coal and ash in power plants. For these production networks, they need to be responsible for the network redundant communication with multiple switches in the main control room, engineer station, protection system, excitation system, dispatching system and other parts.

In the wind power generation system, the scene environment of SCADA monitoring system of wind farm substation, wind farm video security system and wind turbine remote monitoring system is poor, and the communication guarantee is realized through industrial switch.

For example, the central centralized control part and the communication part generally divide the communication into the internal control communication part of the fan, the network communication part between the fan and the fan or between the fan and the control center according to different fan networks. The communication inside the fan mainly refers to the communication between the fan cabin and the tower base. The optical fiber ring network is used to form a 100m redundant ring network for the nearby fan. Each redundant ring network is connected to the local control center, which is connected with the remote monitoring center. The wind power communication generally adopts optical fiber connection. Therefore, the wind power industry has a great demand for industrial switches, and each fan needs switches for communication, According to the known national plan, the market demand for industrial switches will double in the next few years.

What we know is that both thermal power plants and wind power generation are in places with large temperature difference between day and night, large wind and sand and harsh environment. Therefore, industrial ethernet switches are generally required:

1. Excellent quality, excellent material, strong lightning, moisture and electromagnetic resistance;

2. The temperature difference between day and night is large. The working temperature is required to reach - 45 ~ 85 ℃, the storage temperature is - 45 ~ 85 ℃, the storage humidity is 0 [%] ~ 95 [%], and there is no condensation;

3. In order to ensure the reliability of communication, it is required to establish redundant ring network with small self-healing time;

4. When the network communication fails, it can be smoothly switched to the glory backup route. In order to ensure the security of data, the industrial switch should have comprehensive network security settings.

With the continuous development of the power industry, there will be more and more stringent requirements for industrial ethernet switches. Therefore, technological innovation is very important. Only by continuously optimizing their own products on the basis of existing products can they meet the trend of the development of the times.
