Product feature and application
With a capacity coverage of 3000VA~10000VA, it is designed for high-power scenarios such as industrial overload and power grid matching. It can stably drive heavy-duty loads such as large production lines, heavy industrial machinery, and power grid distribution station equipment. It can operate continuously for 24 hours without pressure under rated load; Supporting 30% short-term overload, it can easily cope with peak power surges during the start-up of heavy motors, compressors, and other equipment (starting power is 5-8 times the rated power), avoiding overload shutdown and adapting to complex load requirements in high-power scenarios.
Efficient and energy-saving operation, leading the industry in losses
Adopting top-grade magnetic oriented silicon steel core and high-purity oxygen free copper wire wide winding, the magnetic permeability far exceeds that of ordinary silicon steel sheet, and the conductivity is extremely excellent, greatly reducing no-load loss and load loss; The transformer efficiency is as high as 97.5%~98.5%, which is at the leading level in the industry and far superior to traditional large capacity transformers; Low energy consumption and minimal heat generation during operation, long-term use can significantly reduce industrial electricity costs, in line with the national dual carbon policy and green industry concept.
The core components adopt military grade processing technology, with wide and precise winding of the windings, high voltage and tight stacking of the iron core, minimal magnetic circuit loss, output voltage fluctuation error of ≤± 1%, and voltage stabilization performance reaching grid level standards; Adapt to 50/60Hz power frequency, output waveform distortion ≤ 2%, no harmonic interference, can safely supply power to loads with extremely high power supply quality requirements such as large data center server clusters, precision industrial equipment, and power grid supporting equipment, ensuring zero equipment failures and zero data transmission interruptions.
Equipped with an intelligent constant temperature heat dissipation system, it adopts a triple heat dissipation structure of "large area heat sink+dual high-speed silent fan+oil circuit auxiliary heat dissipation (high-pressure version)", matched with high-precision temperature sensors. The fan automatically adjusts the speed according to the device temperature, operates silently at low temperatures, and fully dissipates heat at high temperatures to ensure that the device temperature is stable within a safe range; The heat dissipation channel has been optimized by fluid mechanics to quickly dissipate heat, ensuring that the equipment can operate continuously for a long time without overheating risk in full load, high temperature, and harsh environments.

FAQ
Q: Can large capacity transformers convert DC voltage?
A: It's not possible. This series of high-capacity transformers are power frequency AC transformers, only suitable for AC voltage conversion and cannot directly convert DC voltage. If it is necessary to convert DC voltage, it is necessary to use industrial grade high-voltage rectifiers, inverters and other equipment to convert DC voltage into AC voltage, and then transform it through this transformer; Alternatively, industrial grade high-voltage direct current converters can be directly selected to avoid equipment damage and high-voltage safety risks.
Q: How to choose a large capacity transformer with appropriate capacity? Do we need to reserve a margin?
A: The selection of capacity should be based on the total load power and starting characteristics. It is recommended to reserve 50%~80% of the capacity for high-power overload scenarios to avoid overload and peak power impact. ① Calculate the total power of the load: Add up the rated power of all devices that need to be powered (unit: W), with a focus on inductive loads such as motors and compressors (starting power is 5-8 times the rated power); ② Choose transformer capacity: Transformer capacity (VA) ≥ total load power (W) × (1+50%~80%). Example: The total load power is 3000W (including multiple heavy-duty motors), with a 60% margin reserved. A transformer with a capacity of ≥ 4800VA should be selected, and the recommended model is 5000VA. Reserve sufficient margin to ensure stable start-up of heavy equipment, avoid the impact of power grid fluctuations, and extend the service life of transformers.
Q: Is it normal for the transformer to generate heat during operation? How to ensure the heat dissipation effect?
A: Heating during operation is a normal phenomenon, and it is safe for the shell temperature of a large capacity transformer to not exceed 80 ℃ when operating at full load. When the transformer core and winding work, losses are generated, which are converted into heat. The intelligent constant temperature cooling system equipped on the equipment can effectively dissipate heat: ① Dual silent fans automatically start and stop to adjust the speed according to the temperature, running at full capacity at high temperatures and silent at low temperatures; ② Large area heat sink+oil circuit auxiliary heat dissipation (high-pressure version), accelerating heat conduction and discharge; ③ The core components are tightly fitted and reinforced, and heat is quickly transferred to the outer shell. Attention to ensuring heat dissipation: ① Reserve at least 1m of heat dissipation space around the transformer to avoid stacking debris and blocking the heat dissipation holes; ② Keep the heat dissipation holes and dust screen unobstructed, and regularly clean the dust; ③ Avoid prolonged full load operation in confined spaces, high temperatures, and high humidity environments; ④ Regularly inspect the oil circuit and cooling system of the high-pressure model to ensure normal operation.
Q: Can high-voltage equipment (10kV/11kV) use 380V mains power or convert to other voltages through this transformer?
A: Okay. Just select the high-voltage customized version corresponding to the input/output voltage based on the rated voltage of the high-voltage equipment (such as selecting 380V input/10kV output or 10kV input/380V output for 10kV equipment). Attention during use: ① Confirm that the rated voltage and rated power of the high-voltage equipment match the transformer, and reserve 50%~80% margin for power; ② Wiring must be operated by a certified high-voltage electrician, strictly distinguishing between input (INPUT) and output (OUTPUT) terminals, following the wiring diagram and high-voltage electrical specifications to avoid reverse connection and leakage; ③ Only applicable to AC high-voltage equipment, DC high-voltage equipment requires additional industrial grade high-voltage rectification equipment; ④ High voltage models need to be equipped with separate high-voltage protection devices and grounding systems, and undergo regular insulation testing.
