SG series three-phase dry-type transformer

Description

SG series three-phase dry-type transformers are industrial oil-free safety power supply units featuring fire resistance, explosion protection, low loss, strong anti-interference ability and excellent insulation performance. They are widely used in key industrial fields such as power distribution assemblies, testing equipment and automation control systems, providing stable, isolated and properly matched three-phase power for various loads.
1.Application in Complete Electrical Equipment
As the core power supply unit for high and low voltage distribution cabinets, power cabinets, frequency conversion control cabinets and reactive power compensation cabinets, it provides isolated three-phase power for internal control loops, protection components and driving devices. It can realize step-up and step-down conversion of industrial voltages such as 380V/400V/480V to meet voltage matching requirements of different complete sets of equipment, while isolating grid harmonics and surges to improve operational reliability. It is widely used in standard cabinet types such as MNS, GCS, GGD and various non-standard electrical control assemblies.
2. Power Supply for Industrial Testing and Measuring Equipment
It provides isolated and stabilized three-phase power for motor test benches, transformer testing equipment, electrical aging test devices, new energy test platforms and precision measuring instruments, effectively isolating interference between the test circuit and the power grid to avoid data distortion caused by voltage fluctuations and harmonic interference. It can also be customized with special voltage levels according to testing needs to meet voltage adaptation requirements of export equipment and imported testing instruments, ensuring test accuracy and equipment safety.
3. Application in Automation Control and Industrial Control Systems
In PLC control systems, servo drive systems, robot workstations and intelligent production lines, it provides three-phase isolated power supply, blocks ground potential circulation and high-frequency interference, and protects precision components such as controllers, drivers and sensors from grid noise. Stable voltage output avoids misoperation and shutdown faults, improving the continuous operation capability of automated production lines. It is a key power supply supporting device for intelligent manufacturing and flexible production lines.
4. Power Supply for Machine Tools and Heavy Machinery
Suitable for high-power industrial equipment such as CNC machine tools, machining centers, cranes, fans, water pumps, injection molding machines and mining machinery, it achieves accurate three-phase voltage conversion and electrical isolation, reduces the impact of equipment startup surges on the power grid, and protects motors and driving components from overvoltage and surge damage. The dry-type structure features high temperature resistance and vibration resistance, enabling long-term stable operation in dusty and high-humidity workshop environments.
5. Adaptation to Special Industrial Scenarios
It is suitable for places with high fire safety requirements such as data centers, hospitals, shopping malls and factories. It can also be used for voltage conversion of imported and electromechanical equipment, auxiliary power supply for photovoltaic/energy storage systems, and purified power supply systems. With oil-free, maintenance-free and high-safety characteristics, it meets the strict requirements of modern industry for green, safe and stable power supply.
