The Power of three-phase inverter single-phase network

The Power of three-phase inverter single-phase network There Are cases in manufacturing power tools and equipment accounts from a single-phase voltage source. It basically realize of course you can, but remember that in this case we need to select the frequency drive in tandem with the engine, because the output tog under load should not be the largest of more than 50% of nominal.
Frequency Converter is not only the simplicity of the driven equipment and the various options to include, but explicit as you can imagine the saving of resources. How and where is actually saving money I will try to explain in more detail. And so, saves a lot of reasons, this is one of the main growth cosine Phi (what is this Read school physics course) to about 0.98, that is the efficiency of the entire system grows and the use of parasitic energy cost is reduced significantly. What else is important, the index "Phi" approximately all modes are the same. For example, consider the inclusion of the induction motor without using a drive or frequency Converter. In this case, the cosine Phi is typically of the order of 0.3, that is, as you know 70 percent of the energy is wasted. So the savings is achieved by reducing the cost of completing work projects, less any contactors and cables, dampers and brakes, all implemented in drive technology on an electronic level. It turns out that if you use drive technology (Alcivar, a frequency Converter), the savings will be about 50%. For complex production cycles (drilling rigs, concentrator) is often necessary to integrate a certain area in the total chain of the production process, so to speak to synchronize multiple devices in one cycle. Altiware and frequency converters from other manufacturers have additional control inputs involving them, you can synchronize the operation of the equipment. One process is dependent on the other, say, until the pipeline reaches the desired level, the motor side conveyor will not turn on and the discharge valve is not activated (it is used at airports for baggage sorting, complete with microcontroller). The synchronization process can often be seen in the work of milling machines, where depending on the efforts of the tool can be adjusted and the speed of rotation of the head and the feed rate. If one Altivar frequency drive or the company, then it is not that big of a problem for high-frequency harmonics, but when the drive technology on a piece of land a lot, the issue of protecting the network from higher harmonics becomes relevant. Use short cable between asynchronous electrical surge protectors. Just apply throttle, they are used in the chains of LC filters and jump-current quench.
