"At present, the internationally leading high-voltage switchgear products have such functions as disconnection loop disconnection monitoring, operation time detection, contact parts detection and spring energy storage time detection, etc. All these functions constitute a smart high-voltage switch." Investment adviser Song Zhichen, an energy industry researcher, told China Electric Power Daily in an interview with reporters that as the market size and industry continue to expand, the growth rate of the industry shows a downward trend. China's high-voltage switchgear industry should take the opportunity of building a comprehensive smart grid. , Enhance the ability of independent innovation, and greatly enhance the intelligent switching equipment.
High-voltage switch to the intelligent direction
"Under the good situation of the development of high-voltage switchgear industry, manufacturers have stepped up the research and development of new-type high-voltage switchgears, paid attention to the improvement of product performance and quality, tried their best to extend the industry horizontally and vertically, and actively developed high-end products. In the process, intellectualization will be its main development direction. "Yang Zhihua, the deputy general manager of Siyuan Electric Co., Ltd. (hereinafter referred to as" Siyuan Electric ") and the general manager of domestic marketing center, said in an interview with" China Power Daily ".
In fact, high-voltage switchgear will combine functions such as control, signaling, protection, measurement and monitoring to enable high-voltage switchgear to function in continuous self-monitoring as well as direct connection to plant control systems to achieve any combination of these multiple functions, And this technology will guide the future development of high-voltage switch technology trend. At present, the internationally renowned brands of high-voltage switch products have the following features, such as the action time detection, spring storage time detection, temperature / humidity detection and monitoring of the door.
In the view of some experts, large-scale key enterprises of high-voltage switchgear should further develop the technical research on the key technologies and key components of UHV switchgear and achieve the goal of UHV equipment based on domestic and independent R & D and full realization of localization. Combined with the construction of smart grid, digital substation and distribution network automation, the intelligent high-voltage switch is vigorously promoted.
According to "Research Report on Production and Marketing Demand and Investment Forecast of China's High-voltage Switchgear Manufacturing Industry from 2013 to 2017" issued by Prospect Industry Research Institute, "During the 12th Five-Year Plan" period, China's high-voltage switchgear industry will take the opportunity of the overall construction of smart grid, AC and DC input electrical drive based, and constantly enhance the capability of independent innovation, to enhance the high-voltage switchgear to increase the intelligence level, promote environmental protection, energy saving, emission reduction efforts equipment; further enhance the overall technological level and the international competitiveness of high voltage switch industry, efforts High-voltage switch to achieve the industry from big to strong changes.
High-voltage switchgear market is the booming power market in our country, whether the value-added electricity market directly affects the development of high-voltage switchgear market. "In recent years, the phenomenon of globalization and high demand demonstrated by the power transmission and distribution equipment market has greatly contributed to the rapid development of China's high-voltage switchgear market." Yang Zhihua pointed out that in recent years, the rapid development of high-voltage switchgear industry In the next few decades, with the development strategy goal of combining the continuous development of our country's social economy and the further promotion of science and technology, the market prospect of high-voltage switchgear is attractive.
At present, the intelligent trend of high-voltage switch is obviously enhanced. To meet the needs of smart grid construction, intelligent power equipment has also been a great concern of manufacturers and users. The ever-increasing level of equipment intelligence has led to the widespread use of modern sensing technology, micro-processing technology, condition monitoring and fault diagnosis techniques. Today, the replacement of electrical products is very frequent, often in a short period of time, out of many old-style product line. Intelligent components in the electrical at the same time, high-voltage switch also continue to move forward in the direction of intelligence.
Technology bottleneck into the switch intelligent key
"The rapid development of industrialization and urbanization drive the continuous growth of power demand and the development of electrical equipment industries such as high-voltage switchgear are facing good development opportunities.However, the intelligent switch industry in our country faces many difficulties and the bottleneck of technology undoubtedly becomes the key to intelligent transformation." Song Zhichen Especially for the challenges of high-voltage switch intelligent, especially with the large-scale construction of EHV and UHV transmission lines, the development of smart grid, rapid industrialization of electric power and urbanization, high-voltage switchgear industry is facing more opportunities and challenges. challenge.
Some experts believe that to benefit from the domestic UHV and smart grid and other power projects, the demand for high-voltage switchgear in China is on the rise. However, compared with the prosperous markets, the industry faces a series of problems such as product homogenization and overcapacity. In recent years, with overcapacity caused by increased competition, raw materials, labor costs continue to rise, our high-voltage switch industry on the thin ice, the resulting price drop, profit decline for the entire industry to reach a crossroads.
In fact, with overcapacity causing competition intensified, raw materials, labor costs continue to rise, China's high-voltage switchgear industry is facing the pressure of falling prices and falling profits. Under the new situation, the smart grid and UHV construction put forward the intellectualization of high-voltage switchgear New requirement However, with the deepening of market competition, product prices and profits are getting lower and lower, resulting in lack of follow-up R & D and innovation capabilities and difficulties in achieving better development. Some analysts believe that high-voltage switch industry consolidation and reshuffle pushed to the cusp of reform, the industry generally use the Ebb and Tide to describe the current high-voltage switch facing the embarrassing situation.
"As an important part of transmission and distribution project, the high-end technology of high-voltage switch is monopolized by foreign companies. In recent years, large-scale backbone enterprises in the domestic high-voltage switchgear industry have been carrying out technical research on core technologies and key components of UHV switchgear. To achieve UHV equipment based on the domestic, independent research and development, the full realization of localization made a lot of efforts. "Qian Wang senior industry researcher, analyst Zhang Yuanyan high voltage switchgear made recommendations.
Coincidentally, chapter changlan and Yang Guanghua's point of coincidence. "Under the current market environment, the high-voltage switchgear only needs to excavate the potential for sustainable development, and how to prevent the high-voltage switchgear with huge living pressure from being eliminated to ensure product quality and innovation is the top priority." Yang Zhihua told the "China Power Daily" reporter, and for those who still have spare capacity of high-voltage switchgear, the most consideration should be the next step in the direction of product diversification, high-end may be a good choice.
