Special high-voltage and impulse capacitors

ksviiCapacitor Batteries are widely used in AC electricity transmission lines (ETL) which are switched on either in-parallel (shunt) or in-series into a break of ETL (series), and serve to increase transmitted power along ETL and to increase a stability of power energy system operation. Special capacitors and capacitor blocks are used to complete batteries.

At electrical energy transmission along DC ETL the capacitors take a big specific weight in the equipment (about 30% of ETL total cost), which are used as damping and equating elements in transforming/converting devices and also to complete filter and shunt batteries at accepting and sending ends of line.

Over the last years power semi-conductive (thyristor) converting devices for electric drive control are widely used which replace a contact-rheostatic control. One of the most important elements of these devices are capacitors meant for reactive power compensation, higher harmonics filtration and oscillations damping.

Application:
* for operation in batteries of inductive furnaces and other electrothermal plants;
** for power factor correction for shunt and filter batteries of DC ETL;
*** for power factor correction of AC electrical plants of frequency 50 Hz and for using in explosion-proof electric equipment of underground electric power supply systems of mines;
**** for operation in plants of longitudinal compensation of ETL reactive resistance;
***** for operation in shaping lines of impulse devices and other impulse plants;
****** for operation in circuits of AC auxiliary machines of electric locomotives.
