High-voltage capacitor banks upgraded

Non-adjustable capacitor banks UKL(P)

non-adjustable.jpg

Capacitor Banks 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 the 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 an additional load.

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

Capacitor Bank description

By the design the banks UKL(P) 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 the input cell door there are amperemeters and signaling lamps. Left of the door there is a drive of disconnector's main blades and blocking locks for a protection from the access to current-carrying parts when the bank is switched on. 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 static capacitor banks;
  • 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 if input cell door is closed.
