　　高压变频器

　　高压大功率变频调速装置被广泛地应用于大型矿业生产厂、石油化工、**供水、冶金钢铁、电力能源等行业的各种风机、水泵、压缩机、轧钢机等。

　　在冶金、化工、电力、**供水和采矿等行业广泛应用的泵类负载，占整个用电设备能耗的40%左右，电费在自来水厂甚至占制水成本的50%。这是因为：一方面，设备在设计时，通常都留有一定的余量；另一方面，由于工况的变化，需要泵机输出不同的流量。随着市场经济的发展和自动化，智能化程度的提高，采用高压变频器对泵类负载进行速度控制，不但对改进工艺、提高产品质量有好处，又是节能和设备经济运行的要求，是可持续发展的必然趋势。对泵类负载进行调速控制的好处甚多。从应用实例看，大多已取得了较好的效果(有的节能高达30%-40%)，大幅度降低了自来水厂的制水成本，提高了自动化程度，且有利于泵机和管网的降压运行，减少了渗漏、爆管，可延长设备使用寿命

　　高压变频器的种类繁多，其分类方法也多种多样。按着中间环节有无直流部分，可分为交交变频器和交直交变频器；按着直流部分的性质，可分为电流型和电压型变频器；按着有无中间低压回路，可分为高高变频器和高低高变频器；按着输出电平数，可分为两电平、三电平、五电平及多电平变频器；按着电压等级和用途，可分为通用变频器和高压变频器；按着嵌位方式，可分为二极管嵌位型和电容嵌位型变频器等等。

　　High voltage frequency converter

　　High voltage and high-power variable-frequency speed regulation devices are widely used in various fans, water pumps, compressors, rolling mills, etc. in large mining plants, petrochemical industry, municipal water supply, metallurgical steel, electric energy and other industries.

　　Pump loads widely used in metallurgy, chemical industry, electric power, municipal water supply, mining and other industries account for about 40% of the energy consumption of the entire electrical equipment, and electricity charges even account for 50% of the water production cost in waterworks. This is because: on the one hand, equipment is usually designed with a certain margin; On the other hand, due to the change of working conditions, the pump needs to output different flows. With the development of market economy and the improvement of automation and intelligence, using high-voltage frequency converter to control the speed of pump load is not only beneficial to improve the process and product quality, but also the requirement of energy saving and equipment economic operation, which is the inevitable trend of sustainable development. There are many advantages of speed control for pump loads. From the application examples, most of them have achieved good results (some energy saving is as high as 30%-40%), greatly reducing the water production cost of waterworks, improving the degree of automation, and facilitating the depressurization operation of pumps and pipe networks, reducing leakage and pipe burst, and prolonging the service life of equipment

　　There are many kinds of high-voltage frequency converters, and their classification methods are also diverse. According to whether there is DC part in the intermediate link, it can be divided into AC frequency converter and AC DC AC frequency converter; According to the nature of DC part, it can be divided into current type and voltage type frequency converters; According to whether there is an intermediate low-voltage circuit, it can be divided into high-high frequency converter and high-low frequency converter; According to the number of output levels, it can be divided into two-level, three-level, five level and multi-level frequency converters; According to the voltage level and purpose, it can be divided into general frequency converter and high-voltage frequency converter; According to the embedding mode, it can be divided into diode embedding type and capacitor embedding type frequency converters, etc
