PFIZER is a research-based biopharmaceutical company founded in 1849 and headquartered in New York, USA. Pfizer inc. 's products include lipitor, oral antifungal diflucan and antibiotic cixotamax. It is the largest foreign pharmaceutical enterprise in China and has been listed in the world's top 500 for many years. It also has a branch in Singapore. This time, YT Electric exported Active Harmonic Filter Cabinet (AHF) to Singapore and cooperated with Pfizer, one of the top 3 pharmaceutical giants in the world, to bring the products of YT to the world. Whether a medical production equipment can exert its maximum efficiency is not only directly related to the technical performance of the machine itself, but also has an extremely important relationship with the quality of the power supply. For pharmaceutical giants like Pfizer, the quality of power supply will directly affect the stability and reliability of equipment operation, and even lead to major production equipment accidents and huge economic losses. Pharmaceutical production equipment has the characteristics of high power supply continuity and reliability requirements, and there are many challenges such as complex distribution system, difficult daily management, low efficiency of operation and maintenance. There are many harmonic sources in the distribution system of pharmaceutical production, which will produce a large number of harmonics and seriously pollute the power grid, resulting in power quality problems such as excessive harmonics and neutral line harmonic overload. These problems will affect the use of the device. The following problems need to be considered in determining the power supply scheme of medical equipment. Harmonics will lead to the failure of image acquisition equipment, which may lead to data error, image blur, information loss and other problems, or damage circuit board components and cause medical equipment can not continue to work normally. In particular, when some imaging equipment is affected by harmonics, the internal electronic components may record fluctuations and change the output, which will lead to overlapping distortion or ambiguity of waveform images, and easy to cause the information error of drug development in the early stage; Some instruments with very weak signals may cause information collection errors or even failure to work when disturbed by harmonic , causing significant losses to enterprises. Facing the characteristics of pharmaceutical manufacturing industry, YT Electric provides customers with customized low-voltage electrical system solutions in order to ensure the continuous and reliable operation of the long-term high-load power distribution system and improve the stability of the production process: 1200A low-voltage Active Power Filter helps customers greatly reduce the risk of outage due to power distribution system failure and realize the improvement of production and operation level. Active Power Filter (APF) is a kind of used for...

National Exhibition and Convention Center(Shanghai) is the largest complex of single building and exhibition in the world. Located in the Yangtze River Delta, National Exhibition and Convention Center(Shanghai) serves China and the world with breakthrough planning and design combined with perfect service functions, which is suitable to be used as a venue for business promotion, theatrical performances, forum annual meetings, cultural exhibitions, fashion entertainment and other activities. The main loads of National Exhibition and Convention Center(Shanghai) are elevators/escalators, water supply system pumps and air-conditioning fan inverters, office and computer networks, UPS power supplies, and electronic lighting. These loads will generate a large amount of harmonics during use, which may become a disturbance source that causes harmonic distortion in the low-voltage power supply system, causing pollution to the power distribution system, and even causing harm to the surrounding communication system and even equipment other than the power distribution system.     Faced with the power quality characteristics of the National Exhibition and Convention Center(Shanghai), YT Electric provides customers with customized low-voltage electrical system solutions: 400A Active Harmonic Filter Cabinet in order to ensure the continuous and reliable operation of the automation equipment that has been under high load for a long time, and to improve the stability of the operation of the exhibition center. The Active Harmonic Filter(AHF) device uses advanced power electronic technology to detect the harmonics in the power grid in real time. It also generates an inverse compensation current through the converter to dynamically filter out the harmonics in the power grid. The following is the outcome. After the treatment of the YTPQC-AHF Active Harmonic Filter device, the current waveform is well improved and the harmonic current distortion rate is reduced from 34.7% to 1.5%. YT Electric Co. has effectively reduced the harm of harmonics and ensured the smooth development of various activities in the Convention and Exhibition Center. It also verified the safety, reliability and efficiency of YT Electric's Active Harmonic Filter once again.   Current waveform before compensation Current waveform after compensation Current distortion rate before compensation Current distortion rate after compensation Reactive power and power factor before compensation Reactive power and power factor after compensation    

Jiangsu Shenlong Non-woven Material Co., Ltd. was founded in 2002 and has a history of 20 years of non-woven fabric production. It is a high-quality manufacturer of high-end non-woven fabric integrating research and development, production and after-sales.Factory is located in China's famous non-woven production base-changshu town, Jiangsu province, the factory covers an area of 15000 ㎡, daily capacity of 40 tons, the production of all kinds of short fiber non-woven fabric, non-woven fabric, synthetic non-woven fabric, filter, non-woven cotton, antibacterial cotton, automotive interior materials, oil pads and other non-woven products.The products are widely used in medicine, automobile, leather, sports shoes, home textile, smart home and other fields. Factory equipment mainly includes carding machine, needle machine, non-woven oven, coil machine, etc., which will produce a large number of harmonics in the production process, resulting in the field capacitance compensation cabinet can not work normally, often appear capacitance drum and contactor burned out.To ensure the normal operation of the site capacitor cabinet, the 300A Active Harmonic Filter Cabinet (AHF) is installed on site for harmonic control. The field voltage distortion rate is 5.9%, exceeding the national standard limit of 5%, the current distortion rate is 23.5%, the harmonic current is mainly 3 and 5 harmonics, but also contains a small number of 2 and 4 even harmonics.After treatment through Active Harmonic Filter Cabinet (CAHF), the voltage distortion rate drops to 4.2%, the current distortion rate is reduced to 2.0%, and the field capacitor capacity compensation cabinet can operate normally, with no operation failure.
