High-voltage capacitor banks upgraded

ust-kond-vys-napr-001Non-adjustable capacitor banks UKL(P)

They are meant for power factor correction (cos φ) of electrical plants of industrial companies and distribution networks for voltage of 6-10 kV frequency 50 Hz with fixed energy consumption at hours of maximum and minimum loads in a work regime of grid assembly unit.

Application of non-adjustable banks reduces current loads at electricity transmission lines and distribution equipment, what gives a possibility to reduce the charges for energy payment, to connect additional load.

Non-adjustable capacitor banks of reactive power compensation are meant for operation in closed industrial rooms at normal operation conditions in the districts of moderate and cold climate.

Bank description

By the design the banks UKL(P)-6 (10) consist of input cell and capacitor cells, the quantity of which depends on bank power. The cells present the assembled weldable metal cabinets, inside of which an apparatus of main and auxiliary circuits is placed. An access to the cells is secured through the doors from facade side.

In the input cell there are current transformers, a disconnector with a drive, control and measuring instruments, devices of relay protection and automatics. At input cell door there are amperemeters and signaling lamps. Left of the door there are blocking locks for a protection from the access to current-carrying parts when the bank is switched on and a drive of disconnector's main blades. Right from the door there is a drive of grounding blades.

Three phase capacitors and fuses are installed in capacitor cells. Each capacitor has built-in discharge resistors and is protected by installed fuse. The fuse has an actuation indicator and for its observing there is a peep-hole in capacitor cell doors.

Capacitor banks secure the following:

  • switching on/off of capacitor bank by external high-voltage circuit-breaker;
  • protection from rated current increase;
  • current indication of capacitor batteries;
  • emergency signaling at protection actuation;
  • a blocking which prevents closing and opening of disconnector (for operation with disconnector) at applied voltage onto the bank;
  • a blocking which prevents input cell door opening if capacitor battery is not grounded;
  • a blocking which prevents capacitor cell door opening of input cell door is closed.

In a bank designation: third letter – input cell from the left (L) and from the right (P);
56 - banks with disconnector;
57 - banks without disconnector;
first number after type – rated voltage in kV; second – rated power in kVar. Banks have a protection degree IP32 - for UЗ performance, IP44 – for U1 performance.
The banks are completed with capacitors KEP4-6,3(10,5)-450-ЗU2, KEPЗ-6,3(10,5)-300-ЗU2.
