Turning to the undercurrent, starting from the turn, the fingertips are nearing the end of 2006. At the time of the new and the old, "Power World" and the Guangdong Power Supply Society conducted a large-scale survey of power companies in Guangdong, and face-to-face with the top management of major enterprises. Exchange, deep understanding of the survival and development of power companies, and explore the future development direction of power companies.
Let's taste the ups and downs in recent years, revisit the past and change, what is worthy of our nostalgia, and what is worth our expectation?
Constantly expanding market share, gradually moving towards the international market
We understand that during the visit, the output value of most companies have maintained a good momentum of growth, the average growth rate of about 30%. On the future several years of development we are also full of confidence.
As a variety of power plant electrical equipment and electronics industry basic products in the next few years, the rapid development of related industries will bring greater market demand for power companies. 3G license issuance means that large-scale construction of 3G networks and the engine room; "triple play" and "village project" and gradually expand; to develop railway electrification; the financial industry, the insurance industry as well as government offices and vigorously promote information technology; PC, mobile phones Maintaining a good growth situation with the home appliance industry; the state’s substantial investment in manufacturing industry and infrastructure during the 11th Five-Year Plan period will definitely create a huge new market for power companies.
With the further opening of the Chinese market, China's power products into the world economy on a larger scale and in greater depth. The domestic market is internationalized, and foreign well-known brands are constantly pouring into the Chinese market, which has brought a lot of impact to China's power companies. At the same time, China's power products have also begun to export in bulk, and have considerable market advantages in the international market. Competitive ability.
Emphasis on R&D investment, rapid development of product technology
In recent years, with the advancement of microelectronics technology, especially the upgrading of power devices, the use of new electromagnetic materials, the advancement of power conversion technology, the improvement of control methods and the integration of related disciplines, the performance of power supply products has made great progress. . The emergence of fully-controlled power devices has greatly promoted the development of power technology.
During the visit, we saw that everyone is fully aware of the importance of R&D. The proportion of investment in R&D has increased year by year, and the technical content of products has been continuously improved. Especially in the development of power supply efficiency and power supply applications, we have spared no effort. Everyone agrees that power products are moving toward more integration, intelligence, and high efficiency and reliability.
On the other hand, with the development of various industrial technologies, the requirements for power supply technology are getting higher and higher, the variety of specifications is increasing, the technical difficulty is getting bigger and bigger, and the academic fields involved are becoming wider and wider. The object of special power applications is versatile, novel and complex, requiring special power supply equipment not only to ensure the perfect internal performance, but also to assign a variety of specific external characteristics and external interface methods, which determines The special power supply technology must combine the essence of many disciplines and integrate the scientific and technological achievements of all walks of life. The expansion of the special power supply and custom power supply market will definitely put forward higher requirements for the technical strength of the enterprise.
Going green power, future power
The EU has officially launched RoHS and WEEE this year. The Chinese government has proposed to vigorously develop new energy sources and reduce the energy consumption per unit of GDP. This will push power products to the road of “green products†and “future productsâ€.
At the production site of each company, we can see the importance of environmental protection from the lead-free production process and strict testing procedures. At the same time, everyone also recognized the bright future of new energy sources and increased their investment in energy-saving power sources and new energy sources. Everyone agrees that in the next few years, China's new energy facilities will enter the era of mass production. The current leaders will face the challenge of insufficient capacity, and if the latecomers can seize the opportunity, they will have a chance to get a big cake. Although the development of nuclear power and wind power are still facing different obstacles and shortcomings for the time being, there will be a market for demand, and the pioneers who are the first to enter this "blue sea" will surely win a rich harvest.
Established industry standard
During the visit, Prof. Zhang Zhansong, the president of the Guangdong Provincial Power Supply Society, solicited the opinions of the “General Specification for DC Stabilized Power Supply†that was about to be approved. Everyone unanimously agreed to launch the industry standard as soon as possible and said that they would actively participate. Because the standard use of domestic DC power supply is still not standardized, the power supply used in a specific industry mostly adopts its corresponding industry standard. If there is no suitable industry standard, only other standards can be used. Some directly adopt IEC standards, and some develop their own corporate standards, which brings a lot of trouble to everyone.
Based on the principle of perfection and practicality, combined with the actual use of DC stabilized power supply in China, and referring to the current international DC stabilized power supply standard, the authors decided to modify the four standards of IEC60478 and IEC 61204 as the four sub-parts of this standard. At the same time, combined with the actual situation of China's power supply manufacturing and use industry, some parts of the standard were also revised, and some chapter positions of the original standard were also adjusted. The international standards adopted include:
IEC 60478.1-1974 "Director for DC output stable power supply";
IEC 61204-2001 (Edition 1.1) "Low-voltage DC power supply performance characteristics";
IEC 60478.4-1976 "Test methods for DC output stabilized power supplies other than radio frequency interference";
IEC 61204-3:2000 "Electromagnetic Compatibility of Low Voltage DC Power Supply Units";
The general specification of DC stabilized power supply is divided into four parts, namely:
SJ/T XXXX.1: terms and definitions;
SJ/T XXXX.2: performance characteristics;
SJ/T XXXX.3: Tests other than electromagnetic compatibility;
SJ/T XXXX.4: electromagnetic compatibility;
At present, the industry standard has been submitted for approval. After the announcement, it will play a role in regulating and guiding the domestic power supply industry, and it is also more conducive to the integration of domestic DC power supply products with the international.
