Sunwin Intelligent Power Load Bank: The "Intelligent Hub" of Industrial Power Systems

Driven by the dual goals of global Industry 4.0 and "dual carbon" development, the manufacturing, petrochemical, metallurgical and other fields have put forward unprecedented requirements for the stability of power systems. According to the "2025 Global Industrial Energy Report", in power grids where new energy accounts for more than 40%, the power fluctuation range can reach 70%, while traditional load test equipment has low accuracy and slow response, resulting in an average annual power failure loss of more than 15% for industrial enterprises. With 29 years of technological accumulation, Sunwin Electric has launched an intelligent power load bank, which provides disruptive solutions for industrial power systems with the dual engines of "full-scenario adaptation + digital operation and maintenance".

Core technology breakthrough: redefining load test standards

1. Intelligent dry load technology to solve industrial environment problems Sunwin's intelligent power load bank uses a self-developed intelligent dry load module, which achieves 0.5% power accuracy control through high-precision resistor components and intelligent temperature control systems. Compared with traditional liquid-cooled loads, its volume is reduced by 40%, the heat dissipation efficiency is improved by 30%, and no coolant maintenance is required, avoiding the risk of leakage in scenarios such as petrochemicals. For example, in the CNOOC offshore platform project, the equipment can operate continuously in extreme environments of -40℃ to 70℃, and has passed the IP55 protection certification to effectively resist salt spray erosion.

2. Full-dimensional data acquisition to build an industrial power "digital twin" The equipment integrates a multi-dimensional sensor array to monitor 50+ parameters such as voltage, current, harmonics, and temperature in real time, and supports 2-40 harmonic analysis. With the intelligent testing software developed by Sunwin, it can automatically generate load sudden addition/sudden unloading curves and power accumulation reports to improve testing efficiency. For example, in the test of the electric furnace power supply system of a metallurgical plant, the equipment analyzed the voltage distortion rate and warned of transformer aging risks in advance, avoiding equipment downtime losses.

3. Modular design, "customized on demand" products for industrial scenarios support free power combination (1kW-2872kVA), and can customize the proportion of resistive, inductive and capacitive loads according to needs. For example, the AC400-1000kW load cabinet customized for a certain automobile manufacturing plant realizes multi-production line collaborative testing through the parallel function, ensures the power stability of key equipment such as welding robots, and reduces the failure rate of production lines.

Benchmark cases in the industrial field to verify technical strength

1. Petrochemical: Ensure the safety of "black blood" In a certain 10 million ton refinery project, Sunwin AC10.5kV-2200kW high-voltage intelligent load cabinet has achieved the following value: Energy efficiency optimization: By simulating the real load of the refining unit, it helps customers discover the redundancy of the power supply system and save electricity costs. Fault warning: Real-time monitoring of the harmonic distortion rate of the UPS system, discovering the hidden dangers of capacitor aging 7 days in advance, and avoiding the shutdown of the catalytic cracking unit due to power fluctuations.

2. New energy field: Accelerate the transformation of energy structure In a photovoltaic power station project, Sunwin load bank completed the high-voltage ride-through test to verify the stability of the inverter when the grid voltage fluctuates, ensuring the efficient grid connection of new energy power. In addition, the equipment supports dynamic load testing of hydrogen fuel cells, providing key technical support for the development of the hydrogen energy industry.

3. Ship and offshore engineering: "Invisible Guardian" in harsh environments Sunwin products have passed the IP55 protection level certification and can operate stably in extreme environments of -40℃ to 70℃. For example, the intelligent load bank customized for a submarine unit can simulate complex underwater working conditions and ensure the reliability of shipboard generator sets. Its test data helps customers pass the stringent certification of the International Maritime Organization (IMO).
