Kkg-Ggd-LV AC Low Voltage Switchgear

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.
