Intelligent Low Voltage Protection Devices , Low Voltage Reactive Power Compensation Cabinet




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℃
~45℃,humidity≤90% at 20℃ and ≤50% at 40℃,
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.
