HYMSVC series high voltage dynamic reactive power compensation device
MSVC magnetically controlled dynamic reactive power compensation complete set is a reactive power compensation and voltage optimization automatic control device integrating MCR, capacitor group switching and transformer on-load voltage regulation functions. MCR is a “magnetic valve” type controllable saturable reactor, which changes the magnetic saturation of the iron core through the excitation of the DC control current, so as to achieve the purpose of smoothly adjusting the reactive power output. Due to the grouping of capacitors, it realizes two-way dynamic continuous adjustment of reactive power. In addition, the MCR capacity only needs to be close to the maximum capacity of a single group of capacitors to achieve reasonable compensation requirements, reduce equipment costs, and greatly reduce operating losses.

Special filter compensation device for HYFCKRL series submerged arc furnace
Submerged arc furnace is also called electric arc furnace or resistance electric furnace. One end of the electrode is embedded in the material layer, forming an arc in the material layer and heating the material by its own resistance. It is often used for smelting alloys, smelting nickel matte, matte copper, and producing calcium carbide. It is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. It mainly produces ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten and silicon-manganese alloy, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. Its working feature is to use carbon or magnesia refractory materials as the furnace lining, and use self-cultivating graphite electrodes. The electrode is inserted into the charge for submerged arc operation, using the energy and current of the arc to smelt metal through the energy generated by the charge and resistance of the charge, feeding successively, intermittently tapping iron slag, and continuously operating an industrial electric furnace. At the same time, calcium carbide furnaces and yellow phosphorus furnaces can also be attributed to submerged arc furnaces due to the same use conditions.
