From reactive to useful 10/14/2015 At the Chelyabinsk Electrometallurgical Plant, it was decided to put up a barrier of reactive electricity, which wasted loads of power without bringing any benefit. “In electricity, there is the concept of the total power of an electric current, which consists of active and reactive components,” says Sergei Ostashkevich, chief electrician at ChEMK. - The active component does useful work. In our case, it melts metal in furnaces. There is no use for us from the reactive component of the power of the electric current, one useless heating of networks and equipment (transformers, cables). To eliminate overloads of electrical installations, reactive power compensation is carried out. For this we have purchased filter compensating devices, which consist of capacitor banks and inductive coils. Their capacity is 15 megawars. Approximately the same amount of reactive energy is emitted by each melting furnace. Two devices have already been installed on the electric melting furnaces and are working successfully. Seven more are to be mounted. “The main advantage of installing these devices is that energy losses are reduced,” adds Sergei Ostashkevich. - After increasing the current, reactive energy leads to heating of the equipment, losses occur. Capacitor banks compensate for this energy. By eliminating reactive losses, we can increase the consumption of active power, and, therefore, increase the production capacity. Thus, the efficiency of the equipment will increase. Previous news Next news The address: 454081, Chelyabinsk region, Chelyabinsk, st.
