Photovoltaic industry
The German government decided to expedite the reduction of subsidies for photovoltaic roof installation projects that began on July 1 and ground installation projects that began on September 1. The new amendments stipulate that FiT subsidies will be reduced by 15%, depending on the growth rate of the photovoltaic market from March to May this year. This move will accelerate the gradual reduction of subsidies as required by the law.
On March 24, Aerospace (600151) disclosed that the company has signed a "cooperation framework agreement" with CGN Solar, a wholly-owned subsidiary of China Guangdong Nuclear Power Group, and plans to implement strategic cooperation through the cooperation of photovoltaic power plant projects at home and abroad. The two sides will jointly invest in the development of high-quality photovoltaic power station projects developed and stored in overseas PV markets in China, and in Europe and the United States, and jointly provide funding, technology, and other resources for photovoltaic power plant projects.
With the completion of the first phase of the industrialization of silicon single crystal materials for renewable energy solar cells used by Inner Mongolia Zhongrong Photovoltaic, the business focus of China Central (002129) has been gradually adjusted from the semiconductor manufacturing industry to new energy materials, semiconductor materials and semiconductors. Device manufacturing industry goes hand in hand. In 2010, the company basically completed industrial transformation and industrial layout, and formed an industrial structure oriented by energy-saving products and new energy products.
Chao Riyue (002506) Chairman of the Board recently stated that in the face of the new pattern of the PV industry beginning to enter the integration period, Chaori Sun will accelerate the involvement of the European solar power station market this year and extend the industrial chain to consolidate and expand overseas markets.

Wind power industry
On March 16, the U.S. Department of Energy and the Ministry of the Interior jointly issued the "National Offshore Wind Power Strategy: Creating a US Offshore Wind Power Industry." This is the first inter-agency cooperation plan for offshore wind power in the history of the United States. The plan focuses on addressing three major issues: the relatively high cost of offshore wind power, technical challenges in installation, operation, and grid integration, as well as the lack of experience in field data and project approval processes. To support the above strategic work plan, US Secretary of Energy Zhu Xiwen and Interior Minister Salazar recently announced a series of major initiatives, including investing US$50.5 million in offshore wind projects and identifying several high priorities in the Middle Atlantic (600558). Wind energy area.
A few days ago, the China Wind Energy Association announced the latest “2010 China Wind Power Installation Capacity Statisticsâ€. The data shows that, compared with the rapidly growing domestic installed capacity, domestic fan exports still remain in the "on paper" stage. In addition, the trend of further increase in the degree of manufacturing concentration in the entire machine has become increasingly apparent.
On March 24, Sinoma Technology (002080) announced that the company’s holding company, Sinoma Technology Wind Power Blade Co., Ltd., sold three types of 1.5MW wind power blade products to Goldwind Technology (002202) and its wholly-owned subsidiary. The amount was 1.729 billion yuan. Sinoma Leaf's main business is technical research, design, manufacture, sales, and technical service of wind power blades. Sinoma Blade sells wind power blades to customers for normal business operations. The signing of the contract will have a beneficial effect on the company's business.
Nuclear power industry
The “Large Advanced Pressurized Water Reactor and High-Temperature Gas-Cooled Reactor Nuclear Power Plantâ€, one of the major national science and technology projects, has made a series of important developments. A large-scale advanced pressurized water reactor joint scientific research system has basically taken shape. A 200,000 kilowatts will be built at the Shidao Bay Nuclear Power Plant in Rongcheng, Shandong Province. The high-temperature cold reactor nuclear power plant demonstration project has completed the preparation work for the site and has the construction conditions for pouring the first concrete tank. At present, the procurement of main equipment for high-temperature gas-cooled reactor demonstration project has been fully completed. All of them have been manufactured under the supervision of the nuclear power equipment manufacturing eagle volume management system. The localization rate of equipment has exceeded 75%, laying the foundation for China's development of the fourth-generation nuclear power technology.
On March 13th, CNOOC Fifth Construction Co., Ltd. contracted Haiyang Nuclear Power Station No. 2 Nuclear Island CV Simplified Part successfully installed in place. This is the first major milestone for the company's 2011 Haiyang nuclear power project. .
On March 12th, China's Yizhong (601106) developed the world's first AP1000 nuclear power plant one-three-one unit regulator underseal header, indicating that China's Chongyi has fully manufactured all the forgings of the nuclear-island primary circuit of the AP1000 third generation nuclear power plant. Ability to achieve autonomy and batch.
Smart Grid Industry
On March 16, the Twelfth Five-Year Plan outline of China's national economy and social development authorized by the Xinhua News Agency pointed out: “Accepting the requirements of large-scale cross-regional transmission and new energy generation and grid connection, accelerate the construction of a modern power grid system, and further expand West-to-East power transmission scale, improve the regional backbone network, develop high-capacity, high-efficiency, and long-distance advanced transmission technologies such as UHV, rely on advanced technologies such as information, control, and energy storage to promote the construction of smart grids and effectively strengthen the construction and transformation of urban and rural power grids. Enhance the power grid to optimize the allocation of power capacity and reliability of power supply. Among them, UHV and smart grids have been explicitly included in the “12th Five-Year†energy transmission channel construction.

6V Dc Worm Gear Motor is the most common used worm gear motor. 6v worm gear motor has a low efficiency, so while working, it is necessary to save energy as much as possible.
DC Worm Gear Motor including a dc motor with a worm gearbox. A worm gearbox means the output shaft is vertical with the dc motor shaft. Connecting the gears with the motor, there is a worm gear. Dc Worm Gear Motor has very low efficiency, normally for the first stage, the efficiency will loss at least half. However, dc worm gear motor is widely applied on some products need with self-lock function. Like the automatic range hood in the kitchen, or the roller blind motor.
The dc worm gear motor has the following characteristics:
1. Achieve great speed reduction through high gear ratio. Normally reduce the speed as low as 3-5 rpm.
2. Achieve vertical transform by the worm gear
3. With self-lock function to prevent the back-driving.
