公司与产品

“上水”历经十五载,成功研制出世界首套SWS-k型无刷双馈高压交流电机及智能调速系统。该系统构思巧妙新颖,结构科学合理,拚弃了传统的交流电机结构模式和调速理念,实现了用1/3功率380V智能控制器调速10kV高压电机的世界顶级技术!完全颠覆当今世界广泛应用的高压变频电机调速原理,继而成为传统电机、进口等变频传动设备的替代产品。该系统比起传统设备,拥有高效节能、运行可靠、经济廉价等方面优势,真正为用户创造更加卓越而又实际的价值与体验,实现中国制造向中国创造、中国速度向中国质量、中国产品向中国品牌的三大转变。真正为世界节约资源做到工业低碳运行,实现国家节能减排大方针。

 

技术与研发

我们知道,在电机工业领域里,需要变频调速来控制电机的运转,以达到实现电动机软启动、节能、无级变速、自动化控制、设备保护等目的和效益。而目前在水利、电力、冶金、化工、市政等领域,使用的高压大功率电机多采用鼠笼式感应电机、绕线式感应电机、双馈电机等,这些电机都有各自的缺点和局限性(如:尖峰电压与谐波)。特别是容量的不断扩大使得鼠笼式电机的变频容量不断上升,增加了变频器的生产技术难度和维护保养成本;绕线式感应电机转子的有碳刷结构使其运行可靠性大幅降低,定期维护使其运行成本也相应提高。

而SWS-k型无刷双馈交流电机及智能调速系统取消了电刷和集电环,可以在0-100%范围内灵活调速,并且安装尺寸与国家现行交流异步电动机安装标准尺寸一致,同时解决了交流调速电动机无刷化,小容量低压控制器控制高压电动机的两大问题。该产品必将成为传统电机、进口变频等传动设备的替代产品。

 

应用与成果

目前,该产品获得国家多项发明专利并成功商用,已通过国家水利部新产品技术鉴定:《产品技术国际领先》!已通过国家电控配电设备监督检验中心、天津天传电控设备检测公司及陕西省泵(电)站监测调试中心检测,各项指标均达到或超过国家相关标准,特别在节能调速时功率因数和效率均高于其他异步电机30-50%,且运行稳定、安全可靠!

 

 

Abstract

Company and Product

After 12 years, “Sheung Shui” successfully developed the world’s first SWS-k brushless doubly-fed high voltage AC motor and intelligent speed control system. The system is ingenious and novel, the structure is scientific and reasonable. The engineers abandoned the traditional AC motor structure and speed control concept, and realized the world’s top technology of controlling the speed of 10kV high voltage motor by a 380V (1/3 power of ordinary speed control system) intelligent controller! It completely subverted the speed control principle of high voltage frequency conversion motors that wildly used in the world, and became the alternative product of traditional motors, imported frequency conversion equipment and other transmission equipment. Compare with traditional equipment, it’s with the advantages of energy efficient, reliable and economical; it creates extraordinary and actual value and experience; it implemented three changes of “made in China to made in China, Chinese speed to Chinese quality and Chinese products to Chinese brands”. It truly conserves the resources of the world and actualizes low carbon industrial operations and energy saving.

 

Technology and R & D

As we all know, in the motor industry field, we apply the frequency conversion to control the operation of the motors to actualize soft start, energy saving, stepless speed change, automated control, equipment protection and other purpose of the motors. Currently in the industry fields of water conservancy, power, metallurgy, chemical industry, municipal administration and others, mainly squirrel cage induction motors, winding rotor induction motors and doubly-fed motors are used. These motors have their own shortcomings and limitations (such as peak voltage and harmonic wave). In particular, the expanding of the capacity increases the capacity of frequency conversion of squirrel cage motors, which increases the producing difficulties and maintenance cost; the carbon brush greatly reduces the operational reliability of winding rotor induction motor, maintenance routine increases the operational costs.

Without electric brush and slip ring, SWS-k brushless doubly-fed high voltage AC motor and intelligent speed control system is capable of control the speed at a range of 0-100% flexibly. The installation dimensions are the same as current national standard AC asynchronous motors; further more, it realized the facts of brushless of high voltage AC speed control motor and low capacity low voltage controller controls high voltage motor. This product will definitely become the alternative product of traditional motors, imported frequency conversion equipment and other transmission equipment.

 

Applications and Achievements

Currently, the product has obtained many national patents and successfully applied commercially. The product also passed new product technical appraisal by Ministry of Water Resources: International leading technology! Furthermore, the product has passed the tests of National Electric Power Distribution Equipment Supervision and Inspection Center, Tianjin Tian Chuan Electric Control Equipment Testing Co. and Shanxi Pump (electric) Station Monitoring and Testing center. The indicators have met or exceeded the relevant national standards, particularly the power factor and efficiency are 30%-50% higher than other asynchronous motors during the process of speed control, stable operation, safe and reliable!
