PRODUCT STRUCTURE . The basic structure of the power distribution
device is fully enclosed indoors. It is assembled and welded by 8MF
profile with high strength, and the incoming and outgoing cables
can be introduced from the bottom of the box, and there are doors
in front and rear of the box, locks on the doors, control switches,
measuring instruments and signal indicators on the front door. The
rear door is for maintenance. The main busbar in the power
distribution device is placed in the upper part of the box and
fixed with high-strength insulators or busbar clamps. The
electrical components are mounted on a mounting plate in the box
and bolted. The upper and lower left and right can be adjusted
freely, and the installation is convenient and flexible.2. The door
and side plate of the power distribution device are made of rubber
sponge to realize the sealing requirements between the door and the
box, and there is a certain slope before and after the top of the
box, which has the effect of anti-drip.3. The power distribution
device can be operated from the front of the box and overhauled
after the box.4. The power distribution device can be used
individually or in groups. FEATURES . The power distribution device
has many schemes, and the internal circuits of each scheme can also
be arbitrarily combined, so as to form a new primary scheme to meet
the needs of feeding, contact, power factor compensation, and
lighting;2. The power distribution device adopts the most advanced
oil-free electrical components of 660V (380V) and 127V voltage
levels in China, with advanced technology, stable and reliable
performance, and high breaking capacity.3. There is an electrical
interlocking circuit between the disconnector and the circuit
breaker or contactor in the distribution device, which can
effectively prevent the accident of pulling the disconnector with
the load.4. The cable entry device of the power distribution device
can prevent the cable from twisting and pulling out and damage, and
there are bolts that are convenient for grounding5. The layout
spacing of the primary circuit bus bar of the power distribution
device and its supporting insulator have sufficient dynamic and
thermal stability. The clearance and creepage distance of the
electrical components in the device meets the provisions of the
relevant regulations;6. The power distribution device has reliable
internal and external grounding devices:7. The performance of power
distribution device humidity, heat, and other performance comply
with the relevant provisions of GB3836 "Explosion-proof Electrical
Equipment for Explosive Atmosphere" CONDITION OF USE .
Ambient temperature: -20°C ~ +40°C; 2. Altitude not
exceeding 1000M;3. Surrounding relative humidity not greater
than 95% (at 25°C); 4. In places without gas, coal dust
explosion hazards and severe vibration in coal mines; 5.
In an environment without gases and vapors that can corrode metals
and damage insulation;6. A small amount of vertical dripping
water is allowed. DESIGN & MANUFACTURE PROCESS Based on more than
30 years of design, manufacturing, and experimental experience in
the transformer industry, CEEG has developed a set of advanced
three-dimensional + parametric design software, which can realize
automatic design, cost optimization, and simulation.Fully
considering the requirements of the national and industrial
standards, ensuring the advantageous design of products.The
high-voltage winding conductor is wound with a high-quality
conductor and reinforced with long and short-cut glass fiber felt.
Poured by the advanced Heidrich vacuum pouring system under vacuum.
Effectively restrain the occurrence of partial discharge, and the
partial discharge is ≤ 5pc.The low-voltage winding adopts a
high-quality foil conductor and is wound on an automatic foil
winding machine. The foil winding machine adopts the patented
technology of foil wire hydraulic energy-saving tension crimping
device, high-precision detection of ±0.5mm, and advanced argon arc
welding technology, which plays a key role in ensuring the quality
of coil winding.The iron core adopts a high-quality high magnetic
conductivity-oriented silicon steel sheet, a 45° full oblique step
lapping process, and the surface adopts special moisture-proof and
rust-proof coating, which effectively reduces the no-load current
and noise level. TESTING All products strictly control the
production process and quality links, and conduct strict tests and
inspections according to national standards and customized
requirements before leaving the factory, including partial
discharge inspection, lightning resistance and electric shock
inspection, noise inspection, and other necessary inspection items.
Advanced test and detection equipment and a perfect inspection and
detection system ensure the high quality and high quality of
products. USE & INSTALLATION SERVICE CONDITIONS - The
installation site shall not be flooded by water, the altitude sh
