| 变频器的种类根据变频器价格，变频器品牌，变频器的工作原理及变频器的作用功能不同，在选型方面需要针对性，同时可以减少后期对变频器维修问题，把变频器进行系统分类综合起来有以下常用种类： Inverter price according to the kinds of frequency converter, inverter brand, the role of the working principle of frequency converter and inverter function is different, need to be targeted in selection, at the same time can reduce the late maintenance problems of the inverter, the inverter system classification together commonly used have the following kinds: 1）按变频器价格大小分类 1) classify the price according to the frequency converter 德力西中高低压变频器 High and low voltage inverter in delisi 可以分为高压变频器，中压变频器和低压变频器，高压变频器价格最高，常用于大型工业设备，中压变频器在工厂车间中应用比较广泛，可以起到节能省电作用，低压变频器可以解决小型设备变频调速问题。 Can be divided into high voltage inverter, medium voltage inverter and low voltage inverter, high voltage inverter price is highest, often used in large industrial equipment, medium voltage inverter is widely applied in the workshop, can have energy saving energy saving effect, low voltage frequency converter can solve the problem of small equipment frequency control of motor speed. 2）按变频器品牌分类 2) brand classification by frequency converter 世界变频器品牌大全 The world converter brand is full 有国产变频品牌，欧美品牌，日本品牌，台湾品牌等 There are domestic variable-frequency brands, European and American brands, Japanese brands, Taiwanese brands, etc 国产品牌：德力西、森兰、佳灵、易能、海利普、海利、乐邦、信诺、科姆龙、阿尔法、日锋、时代、博斯特、高邦、开拓、正弦、塞普信、惠丰、赛普、韦尔、华为、安圣、安邦信 、嘉信、日普、四方、格立特、康沃、吉纳、日川 、威科达、英威腾、春日 、爱迪生等 Domestic brands: delixi, LAN, JiaLing, easy, honest, honest, leeper, cigna, comair dragon, alpha, feng, age, Bosch, merchant, the development, the sine, Rowe, HuiFeng, Cyprus, weir, huawei, AnSheng, amb, schwab, day, four square, grid litas, Cornwall, kino, sichuan, keda, British witten, spring, Edison, etc 欧美品牌： European and American brands: ABB、SEW、伦次、施耐德、CT、科比、西门子、欧陆、G.E.、瓦萨、佛斯、西威、AB、艾默生、罗宾康、安萨尔多、博世力士乐等。 ABB, SEW, roen, schneider, CT, kobe, Siemens, continental, G.E., vasa, foss, west, AB, Emerson, robin kang, ansaldo, Bosch rexroth, etc. 日本品牌： Japanese brands: 富士、三菱、安川、欧姆龙、松下、东芝、超能士 、东冈、东川、三垦、卡西亚、东洋、日立 、明电舍等 Fuji, mitsubishi, anchuan, omron, panasonic, Toshiba, super energy, donggang, dongchuan, sanken, kasia, dongyang, Hitachi, Ming electric house, etc 台湾品牌： Taiwan brand: 欧林、台达、东达、普传、东菱、利佳、宁茂、三基、泓筌、东力、凯奇、盛华 、爱德利、士林、东元、三川、东炜庭 、富华、台安、隆兴、九德松益、腾龙、创杰等。 Orin, Taiwan, east, known, dongling, Leon, sunpearl, sanki, acquisitive Quan, east force, cage, shenghua, Ed, shilin, east yuan, three sichuan, east Hui court, fuhua, taian, the prosperity, nine's benefit, tenglong, gen jie, etc. 3) 按照工作原理分类 3) classify according to the principle of work 变频器工作原理中的各种控制优势 Various control advantages in the operating principle of inverter A、V/f控制--- V/f控制变频器就是保证输出电压跟频率成正比的控制这样可以使电动机的磁通保持一定，避免弱磁和磁饱和现象的产生，多用于风机、泵类节能，用压控振荡器实现。 A, V/f control - V/f control frequency converter is to ensure that the output voltage and frequency is proportional to the control so that we can keep the flux of the motor must be, avoiding the phenomenon of weak magnetic and magnetic saturation, used in fan and pump energy saving more, with A voltage-controlled oscillator to realize. 异步电动机的转矩是电机的磁通与转子内流过电流之间相互作用而产生的，在额定频率下，电压一定降低频率，磁通变大，磁回路趋向饱和，严重时将烧毁电机。当频率与电压要成比例地改变，使电动机的磁通保持一定，避免弱磁和磁饱和现象的产生。 Asynchronous motor torque is within the magnetic flux and rotor motor through the interaction between current, under the rated frequency, voltage must be to reduce the frequency, magnetic flux, magnetic circuit is becoming saturated, serious when will burn machine. When the frequency and voltage are changed proportionally, the magnetic flux of the motor must be kept to avoid the occurrence of weak magnetic and saturation phenomena. B、 转差频率控制---转差调速即改变异步电动机的滑差来调速，滑差越大速度越慢，绕膝是电机转子串电阻，转差频率控制技术的采用，使变频调速系统在一定程度上改善了系统的静态和动态性能，同时它又比矢量控制方法简便，具有结构简单、容易实现、控制精度高等特点，广泛应用于异步电机的矢量控制调速系统中。 B - slip, the slip frequency control speed control or change the slip to speed asynchronous motor, the greater the slip speed slower, RaoXi is motor rotor resistance, the adoption of slip frequency control technology, make the variable frequency speed regulation system to a certain extent, improve the static and dynamic performance of the system, at the same time it than vector control method is simple, has a simple structure, easy to implement and control precision higher characteristic, is widely used in induction motor vector control speed regulation system. |
