Muhimman abubuwa

• High voltage adaptation, large capacity compensation: rated voltage of 35kV ± 10%, output capacity coverage of ±0.1Mvar~±200Mvar, supporting ultra large capacity reactive power regulation (maximum 84Mvar for air-cooled type, maximum 100Mvar for water-cooled type), perfectly adapting to the compensation needs of high voltage distribution networks and large loads.

• Dynamic and static combination, precise compensation: response time<5ms, compensation current resolution 0.5A, supporting capacitive/inductive automatic continuous smooth adjustment. The "dynamic and static combination" compensation method not only meets the basic compensation of steady-state loads, but also quickly responds to voltage flicker caused by impact loads (such as large electric arc furnaces and wind farm fluctuations), with industry-leading compensation accuracy.

• Stable and reliable, durable outdoors: adopting a dual power supply design, supporting seamless backup switching; Redundant design meets the operational requirements of N-2, equipped with multiple protection functions such as unit overvoltage/undervoltage, overcurrent, overheating, and drive failure, comprehensively avoiding operational risks; IP44 outdoor protection level, able to withstand operating temperatures of -35 ℃ to+40 ℃, humidity of ≤90%, seismic intensity of VIII degree, and pollution environment of IV level. The process is mature and durable, suitable for complex outdoor working conditions.

• Efficient and environmentally friendly, with extremely low energy consumption: system power loss<0.8%, no additional transformer loss, significant energy-saving effect; The harmonic distortion rate THDi is less than 3%, which causes minimal pollution to the power grid and meets the environmental protection operation standards for high-voltage power grids.

• Flexible expansion, strong adaptability: supports multiple operating modes such as constant reactive power, constant power factor, constant voltage, load compensation, etc; Compatible with various communication protocols such as Modbus RTU, Profibus, IEC61850-103/104, etc; It can achieve multi machine parallel networking, multi bus comprehensive compensation, modular design for easy expansion in the later stage, and adapt to different high-voltage power grid architectures.
