HYMSVC series high voltage dynamic reactive power compensation device

Short Description:

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.
