TBB0.4 Series Intelligent Reactive Power Compensation Installation is a revolutionary electricity saving product developed by ourselveson the basis of the reference to the structure of opponents from the world. It is equipped with microcomputer control system, which can automatically com pensate the reactive component through intellectualized track.

Basic Principles of the Installation

The automatic reactive-power compensation controller samples thereactive current of the power line. Then the microcomputer n the controller analyzes the sampled current and transmits the control signal to the outputrelay, which controls the special contactor .
of CJ19 type switching capacitor in the compensation cabinet, so as to control the switching of bsmj0.4 serialself-healing type low voltage   shunt capacitor and reduce the line loss andimprove voltage quality.

Main Technical indexes

1.Service conditions: Altitude ≤ 2000m. ambient temperature -25℃ ~45℃, humidity ≤ 90% at 20℃ and ≤ 50% at 40℃, and mounting gradient ≤5°.

  1. Rated voltage: 540VAC, 60Hz.
  2. Rated output:260Kvar.
  3. Operating voltage range (0.85-1.10)times of rated voltage.
  4. Max allowable current: 1.30 times of rated current.
  5. Number of circuits controlled: 11
  6. Switching time: 30-90s/time, adjustable.
  7. Operation method: Automatic, continuous operation.
  8. When the load varies from 5% to 100% the cosφ value remains over 0.95.

General Description

  1. Small size facilitates installation and maintenance of equipment is designed specially for reactive compensation of three-phase transformer with rated voltage 380V and capacity 50-1000KVA.
  2. Controlled by microcomputer and adopting automatic compens ation mode, it has complete functions and reliable performance LEd digital display shows the power factor of power line, ranging from lagging(0.00-0. 99 )to leading(0.00-0.99).
  3. The set values of Cosφ, delay and over-voltage can be set through three functional set keys on the panel keyboard and shown on the digital display. Concise man-machine dialogue facilitates the operation.
  4. With pilot lamp indicating the lagging, leading to operate and over voltage, LED hints program input.
  5. With over-voltage protection function, it is safe in operation. The over-voltage set value has been set at 540V in factory. The users can reset is between 500V and 580V according to their own needs When power line voltage exceeds the set value, Cosφ digital meter is changed automatically and shows the present voltage value of power line. At the same time, it switches off the input capacitors automatically, quickly and step by step. Once the voltage regains normally, This installation will work automatically again.
    6. Having strong anti jamming capability it can resist interference pulse of 2000v input directly through power line. The index exceeds national special standard.

7.Protection degree of Low Voltage Capacitor Bank Cabinet:IP54
