TBBZ High voltage reactive power automatic compensation device

Product Description

Product overview

TBBZ series high voltage reactive power automatic compensation device according to the 6KV and 10KV power supply bus grid and load conditions, through the control system capacitor bank automatic tracking and switching, automatic tracking and compensation of no power, power factor of 0.9 or more. Greatly optimize power quality, energy saving and consumption reduction, improve the transmission capacity of transmission and distribution system.

Model and meaning

For example: TBB10-1500(600+900)-AK indicates that the voltage is 10kV, the device capacity is 1500kvar, divided into two groups of automatic switching, a group of 600kvar, a group of 900kvar, single type wiring, open triangle voltage protection.

Environmental conditions of use

Altitude: no higher than 1000m;

Ambient temperature: -25~+55C;

Relative humidity: 85%;

The operation site is not allowed to have explosive danger of the medium, the surrounding medium should not contain corrosive and damage insulation gas and conductive media, do not allow full of water vapor and serious mold presence.

Key technical data

A single capacitor is guaranteed by a spray type fuse, and each group is equipped with a lightning arrester operating overvoltage and lightning overvoltage protection; Large-screen LCD controller, real-time display system voltage, current, power factor; With RS232/RS485 standard communication interface, and can realize the "four remote" function, each group can be configured with a reactor to suppress harmonic amplification in the closing inrush current;

Rated voltage: 6-10kV;

Rated frequency: 50Hz;

Rated capacity: 100-10000kvar;

Number of groups: 1-5 groups;

Reactor parameter selection: inhibition of closing inrush current, reactance rate is 0.1-1%;

Suppressing more than 5 harmonics, the reactance rate is 6%; More than 3 harmonics are suppressed, and the reactance is 12%.

Product characteristics

The device can run for a long time under the steady-state overvoltage of 1.1 times the rated operating voltage. The device can run continuously under overcurrent with the average root value not exceeding 1.3 times the rated current of the capacitor bank;

The device adopts vacuum contactor to cut and can be operated frequently.

Each group of capacitors is equipped with a discharge coil, which can reduce the residual voltage to less than 50V within 5 seconds;

Each group of capacitors can be protected by relay or microcomputer protection control unit to achieve overcurrent, voltage imbalance, undervoltage and overvoltage protection of the capacitor bank. When a group of capacitors fails, this group of capacitors can be cut off without affecting the use of other capacitors.
