Special high-voltage and impulse capacitors

ksvii

          Static Capacitor Banks 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 static capacitor banks.

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 converting devices and also to complete filter and shunt banks 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.

In capacitors designation, the first number after type is rated voltage in kV; the second – rated power in kVAr. Permissible excesses: as per voltage - 110 %, as per current - 130 %.

Capacitors KEPF(М) for voltages 3,65; 4,4; 6,3; 6,6; 7,3 kV and power 100, 150 и 200 kVAr are manufactured without fuses built inside.
Capacitors are impregnated with ecologically safe dielectric fluid and equipped with discharge resistors.
