General Description

JiukangTM TBB0.4 Series Intelligent Reactive Power Compensation

Installation is a revolutionary electricity saving product developed by

Ourselves on the basis of the reference to the structure of opponents

from the world. It is equipped with microcomputer control system, which

can automatically compensate the reactive component through

intellectualized track.

Basic Principles of the Installation

The automatic reactive-power compensation controller

samples there active current of the power line. Then the microcomputer

in the controller analyzes the sampled current and transmits the

control signal to the out put relay, which controls the special contactor

of CJ19 type switching capacitor in the compensation cabinet, so as

to control the switching of BSMJ0.4 serial self-healing type low voltage

shunt capacitor and reduce the line loss and improve voltage quality.

Basic Principles of the Installation

1. Service conditions: Altitude≤2000m, ambient temperature -25°C

~45°C,humidity≤90% at 20°C and ≤50% at 40°C,

and mounting gradient≤5°.

2. Rated voltage: 400VAC,220VAC, 50/60Hz.

3. Rated output: 22.5, 36, 40, 60, 72, 90, 120, 140, 180, 220, 375 Kvar.

4. Operating voltage range:(0.85~1.10)times of rated voltage.

5. Max allowable current:1.30 times of rated current.

6. Number of circuits controlled:4,6/

7. Switching time:30~90s/time,adjustable.

8. Operation method: Automatic, continuous operation.

9. 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.

It 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 compensation

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 overvoltage,

LED hints program input.

5. With over-voltage protection function, it is safe in operation.(The

over-voltage set value has been set at 420V in factory. The users

can reset is between 400V and 450V 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.
