Domestic solid-state relay product standards improve

This year is a crucial year for the implementation of the objectives of the 12th Five-Year Plan. The “Twelfth Five-Year” development plan of the Ministry of Industry and Information Technology mentions: “Efforts to develop relays, connectors, micro-motors, super Capacitors and other key electronic components; Accelerate the research and development and industrialization of nickel-metal hydride batteries, power-type lithium-ion batteries and battery management systems, and battery grouping technologies for new energy vehicles.”

According to Guo Guosheng, an expert in the domestic relay industry, the rapid development of the new generation of information technology, energy saving and emission reduction, high-end manufacturing transformation, and urbanization construction, which are rapidly cultivated in the planning, has created a huge market environment for the relay industry, and the entire industry is expected to usher in rapid development. In the period, the "Solid State Relay" client will be the biggest beneficiary as a result of the combination of emerging technologies and entities.

Yu Guosheng has been in the relay industry for many years and has extensive industry experience. He also witnessed the development of relays from electromechanical to solid-state. He believes that solid-state relays have advantages unmatched by traditional electromechanical relays. Solid-state technologies respond time, resist electromagnetic interference, and work. The advantages of life and control methods can provide customers with more suitable products, and the combination with mobile internet technology will certainly become the relay industry's future development trend.

According to statistical data from relevant agencies, the market potential of the relay industry in China is very large. In 2008, the market capacity of industrial relays in China was only 1.09 billion yuan. In 2009, the market capacity of industrial relays reached 1.16 billion yuan, and the export of relays reached more than 38 million US dollars. In 2010, China’s relay sales increased to 1.6 billion US dollars. With the gradual implementation of the ten major emerging industry revitalization policies, it is expected that during the “Twelfth Five-Year Plan” period, traditional electromechanical relays will grow at a rate of about 8%, while the development speed of solid-state relays will maintain rapid development at a rate of more than 15%. .

The output of relays in China ranks first in the world. In 2011, the output was 5.47 billion, which accounted for 58.25% of the world's total output. The sales amount was 16.3 billion yuan, accounting for 33.69% of the world's total sales. However, as can be seen from the data, high-end relays with higher profit margins are mainly solid-state relays produced by foreign companies. As domestic manufacturers continue to catch up with and advance in solid-state technology, the product standards of solid-state relays are constantly moving closer to world-class companies. Substitution is gradually being achieved and it is expected to catch up further in global market share.

With a series of relay projects supported by the state, such as "industrialization of HVDC relays and meter components", "low-voltage electrical technology expansion and industrialization", "high-performance relay technology expansion and industrialization", "relay R & D capability With the in-depth development of such projects as the ability to upgrade and upgrade precision components, solid-state relays will be significantly better than conventional electromechanical relays in terms of precision, reliability, and volume, and they can effectively expand domestic communications market share and gradually attack the high-end signal relay market. In the environment where the market policies are very favorable, the "solid-state relay" client will surely lead the entire industry to usher in a rapid and large-scale development.
