The world's first 30MW smart photovoltaic power station settled in Ningxia

As of the 30th, the 30-megawatt photovoltaic power station of the Tianjing Mountain, the world's largest installed smart photovoltaic power station in Ningxia, has delivered 5 million kilowatt-hours of power to the Ningxia Power Grid. The power station was independently designed and built by China Enfi Engineering & Technology Co., Ltd., a subsidiary of the world's top 500 China Metallurgical Group, in Zhongwei Mountain, Zhongwei, Ningxia, and was successfully built on December 22, 2011. The project adopts the intelligent linkage tracking system independently researched and developed by China Enfi. Compared with traditional photovoltaic power plants, it can track the sun in 24 hours, increase the power generation by 25%, and generate an annual average power generation of 54 million kWh, which can be calculated according to the 25-year service life. The increase in power generation capacity was 270 million kwh, and the accumulated carbon dioxide emission reduction was 1.3 million tons.

Located near the Tengger Desert, Zhongwei City belongs to the category of solar radiation and is one of the regions with the most abundant light and heat resources in the country. This intelligent photovoltaic power plant with an annual output value of more than 60 million yuan has only 7 employees. Among them, the average age of technicians is less than 24 years old. Zhang Ning, the general manager, told the reporter that Enfi's self-developed intelligent linkage tracking system continuously adjusts the angle of the rotating bracket that supports the solar panel, and keeps consistent with the sun's operating pattern, continuously and accurately tracking the sun, and greatly increasing the amount of light energy absorbed. With energy efficiency, electricity generation can be increased by 25% compared to conventional photovoltaic power plants. In the main control room, technician Wang Hua introduced to the reporter that Tianjingshan PV power station adopts time-controlled technology and can track the sun in 24 hours. Compared with traditional light control, it saves time and effort. At present, China Enfi has applied for 8 patents related to this R&D result.

The Tianjingshan 30 MW photovoltaic power station will also be the first in China to implement a combination of clean energy power generation and the development of green organic agriculture. The station chooses a single-axis tracking method with an inclination of 8 degrees to allow the space between the panel and the ground to be nearly 3 meters away. This space can be used to develop organic agriculture and aquaculture and improve the utilization rate of land resources. It will build a large-scale desert photovoltaic power station and photovoltaic ecology for Ningxia in the future. Greenhouses accumulate basic data and engineering experience.

SMT Stencil is made of stainless steel, and used for printing the solder paste on the SMT pads when do PCB Assembly job. Ours SMT stencil is high-precision Laser stencils which is OK for 0.3mm BGA PCB Assembly.

 

SMT Stencil could be framed SMT stencil and also could be un-framed SMT stencil.

 

 For un-framed SMT stencil, the biggest size is 280mm*380mm and the valid size is 190mm*290mm. And also the size could be customized if required, just ensure the stencil size is bigger than the PCB boards. Normally, un-framed stencil is used for PCB hand assembly or PCB Prototype assembly which is cheap and convenient.

 

For framed SMT stencil, it has many sizes could be chose and it`s always used for PCB automatic assembly or big quantity PCB assembly. It could be put on the auto solder paste print machine in the automatic SMT line.
