Capacitor unit for reactive power compensation UKKRM 5 series

Capacitor unit for reactive power compensation UKKRM 5Capacitor unit for reactive power compensation UKKRM 5 produced in accordance with with SHEDK.656232.001TY and GOST 27389-87, and designed to improve the power factor in the automatic mode while connected to the mains supply at the transformer substation, or directly to the consumer.

Control of the capacitor unit is provided by automatic controllers of the power factor NOVAR 5 + or NOVAR 114  manufactured by KMV (Czech Republic). The microprocessor-based regulator provides needed level of the power factor with high accuracy and a wide range of compensated power. Regulator NOVAR by RS 485 / RS 232 interface (MODBUS-RTU protocol) allows to configure and monitor the required parameters in real time. CD with software comes with the device.

The capacity unit are made as a single-end service chamber according to GOST 10958-80 and protection level IP31 as to GOST 14254-96. The UKKRM cabined is installed on a foundation.

Connection of the unit to the supply circuit is made by the cable through the bottom entry. Connection also can be carried out through the unit’s roof.

Distinctive features of the used capacitors:

  • Using three-phase capacitors allows significantly (in comparison with single-phase capacitors) to reduce weight and dimensions of the capacitor unit, number of wires and contact connections , increase the reliability of the capacitor unit;
  • The voltage margin of safety: with maximum grid voltage the capacitors loaded only for 80-85 % of the rated voltage potential, thus guarantee rated power in KVar;
  • Capacitors for reactive power compensation have build-in discharge modules. Capacitors discharge occurs in up to 50 V for 60 seconds . This increases the safety of staff and eliminates capacitors overload at next power up;
  • Environmentally friendly: eco-friendly and safe filler (gas or polyurethane resin)  does not pose a threat to humans and the environment.
  • Easy disposal of waste capacitor cans.
  • Self-healing capacitor dielectric provides the ability to compensate reactive power for a long time maintaining rated characteristics;
  • Security services and gap protection: capacitors are equipped with fuses - choppers, which are triggered in any case of overpressure inside the banks. This can happen because of an overcorrect, overheating or end of life due to the large number of self-healing breakdowns.

Capacitor unit orders carried out according to the questionnaire (you can fill it yourself or consult with engineering expert of ChEAZ-ELPRY Ltd center).

The opportunities of computer modeling and design available on the enterprise, as well as rapidly modified manufacturing can not only produce a wide range of serial capacitor units, but quickly develop and manufacture non-standard products according to customer specifications, for example Antiresonant throttles installation (harmonic filters 134/189/210 Hz).

To select capacitor units you can use the program specially designed by ChEAZ-ELPRY Ltd for calculating the power, which allows you to choose the design of the installation according to the mandatory requirements of Russian electric power regulation and the optimum in terms of cost. During years or working we accumulate extensive statistics of various equipment parameters depending on the process and depending on the type of installed equipment.
