With the gradual implementation of the ten industrial revitalization policy, experts predict, "Twelve Five" period, the required amount of the relay and applications will continue to grow, the traditional electromechanical relays will be about 8% growth rate, solid state relays The growth rate will remain at around 15%, special relay is more than 20% of the rate of rapid development. Statistics show that China relay industry has tremendous market potential, China relay industry development direction and has the following features.
Characterized by high barriers to trade with
Electrical equipment is divided into primary and secondary equipment, a device that directly bear the generation, transmission, substation, distribution, electricity-enabled devices, such as generators, transformers, low-tech, many domestic manufacturers, intense competition. Secondary device refers to a device functioning and implementation of a variety of electrical equipment required for management objectives, such as the protection of generators, automated scheduling system. Compared with the same equipment, the production of secondary equipment with high barriers to entry, the industry's product brings together modern electronic technology, communications technology, computer and network technology, with high technological content and high added value, is a typical high technology industries. Although China relay industry after years of development, has made remarkable achievements, but have the capacity to produce domestic enterprises are still only a handful of secondary equipment. Computer Protection is the development direction .
Protection of technological development, and the development of electronics, information and communications technology are inseparable. The future, with further improvement of electronic CT current transformer and voltage transformer PT, the gradual application, IEC61850 protocol standardization, it is foreseeable, digital technology will be more widely used. The country has 110 kV, 220 kVvoltage level of electronic CT, PT Electronic put into trial operation, research and development applicable to electronic CT and PT relay protection equipment, will promote the development of protection techniques to drive relay Protect the new principles, new technologies and new applications become placed in front of relay researchers new topics.
