ROLLER SERVO STABILIZER
The Technology concept of Differential wound linear regulator
with Series Transformer in RED PHASE’S make Automatic Voltage Controller.
We are manufacturing Industrial type Automatic Voltage
Regulators (Stabilizers/Rectifiers) using the differential wound Vertical
Roller Type Regulators. Manufacturing LINEAR TYPE +/- Heavy Duty Regulators
with rollers rolling on both the sides of the coil (as illustrated in the
brochure enclosed). The size of conductor used is more than THREE TIMES than
used in conventional design regulators. Being + type, the same winding is used
for boosting the voltage on one side and bucking the voltage on the other side
of the regulator. So, the rating of the regulator required is half of the
conventional design regulator.
The losses of differential wound linear regulator should be
1/18th of the conventional type regulator and due to heavy section of copper
used in our regulator, overall size is more and practically the losses of our
regulator are 1/5th of the conventional type regulator.
The manufacturing material cost of differential wound linear
regulator is almost more than THREE TIMES the cost of conventional design
Regulator.
As per the Regulator design, the regulator is technically OUT
OF CIRCUIT, When the input voltage is LOWEST/HIGHEST as per the voltage range
of the stabilizer while in stabilizer with conventional brush type regulators,
the regulator is maximum in the circuit and losses are maximum at
LOWEST/HIGHEST as per the range of the stabilizer.
The Actual Efficiency of our stabilizer in running conditions
at 100% Load for the (360-460 V) model will be 99.5% in comparison to less than
approx. 95-96% of conventional type stabilizer for the Automatic Voltage
Controller of similar rating.
WINDINGS
linear Coils are manufactured with copper strips of heavy
cross sectional area instead of copper wires in conventional design with 4-QPC
paper layer cover plus 3 TPC – Polyester film cover for better insulation to
resist the high temperatures on continuous duty cycle with Electrolytic grade
copper strip while taking the current density of 2 to 2.5 amps/mm2 in oil
therefore the maximum temperature rise at full load never goes more than 25
degree centigrade while in conventional design accordingly we use more
copper than any other manufacturer to give the highest quality
with minimum losses for the entire running life of the equipment. Radiators
Cooling is provided to keep the hot spot temp. As low as possible for higher
working efficiency for all the years with lowest temperature rise even on full
load conditions.
CORE
The core is constructed from low loss, cold rolled, grain
oriented, annealed laminations of electrical sheet steel conforming to the
latest internationals standards using grade 4 laminations with thickness from
0.23mm to 0.27mm for minimum no load losses.
CARBON ROLLERS
We are giving self lubricating carbon roller assemblies with
working life of 1 lakh track meters instead of Carbon brush used in
conventional technology. Our rollers are point contact with least wear and tear
as surface area in contact keeps on changing during the running motion and heat
is dissipated through out the body resulting in very high working life on
maximum temperature rise with spring tension be Red Phase to keep the roller
intact with required torque on coil for trouble free operation.
As stabilizers being of Capital equipment, its Life is
considered to be 15-20 years. Considering this, we design our equipment
accordingly introducing further improvements in the construction of equipment
as per feedback received from the customer.
CONTINUOUS DUTY CYCLE
The stabilizers with Roller type Regulators are wound with
heavy section of copper strip suitable for continuous duty on 100% load.
Normally, conventional design regulator are designed for temperature rise of
45*C to 55 degree centigrade. We keep temperature rise between 15*C to 20*C,
which means that our machine can sustain 15-25% overloading without any harm to
the equipment for shorter duration.
LIFE
Life of our stabilizer is more than 20-25 Years as compared to
2-3 years of conventional type stabilizers at FULL LOAD. This is due to the
fact that the losses for our differential wound linear regulator model shall be
least as against maximum of conventional design regulator and therefore due to these
higher losses there shall be more heat generated inside the conventional
regulators, which shall ultimately result in the faster deterioration of the
paper insulation being used for the winding & thereby resulting in
shortening of life of the stabilizer.
In the conventional design regulators, you have to bear the
cost of repair & replacement.
Un-Conditional GUARANTEE
Our equipments are guaranteed unconditionally for FIVE YEARS
against any defects. During this period, we do not charge anything for spares,
services & routine checkups provided to the installation.
SERVICING
We have servicing network all over India for the following
reasons:
To provide prompt/Immediate services to our customers in case
of minor problems.
Regular routine check ups once in two months for checking the
performance of our Stabilizer.
No charges for installation/inspections etc. to be carried out
during the visits of service engineer/technician while others will charge AMC
after the completion of Warrantee period and for routine visits also.
Advantages
By installing voltage controller, you can save 10% to 20%
power consumption of lamps, tube etc. and reduce its failure rate up to 80% if
you are having higher voltage problems. It has been observed that the
industries usually face the problem of both low as well as high voltage
problem. With the installation of AVC and by maintaining 400/230 volts
three/single phase – you will certainly achieve the advantages as explained
under:
Reduction in Breakdown of Electrical Equipments: 60-80%
depending upon the input voltage variation and working hours of the plant.
- Energy Saving: 5-10% depending upon the input voltage variation
and working hours of the plant.
- Reduction in MDI: There will be definite reduction by 10 -15%
after the installation of the equipment.
- Improvement in Power
Factor: There will be definite improvement in the power factor by 10-15% after
the installation of the equipment.
- Uniform Quality of end
product.
- Better Utilization of Existing Transformer and cables.
- Lesser production loss and better efficiency of plant.
