Introduction
A Silent Three-Phase Diesel Generator is a diesel generator that outputs three-phase AC power and controls noise propagation through a silent structure. It is used in industrial, commercial, and other power supply scenarios where both power quality and environmental noise are critical.
Features
Three-Phase Load Matching
The generator employs a three-phase winding structure (typically 400V/50Hz standard output), directly powering three-phase motor loads and reducing line losses and phase imbalance current caused by single-phase conversion.
Voltage Fluctuation Control
Equipped with an AVR automatic voltage regulation system, it monitors the output voltage in real time and adjusts the excitation current to control voltage deviation within ±1%–±2%, reducing operational deviations of sensitive equipment caused by voltage fluctuations.
Noise Propagation Suppression
The generator housing uses a steel plate sandwich structure lined with 50–100 mm of sound-absorbing material, combined with a labyrinthine air intake and exhaust channel, reducing the sound pressure level at a 7-meter testing distance by approximately 15–35 dB(A), minimizing acoustic impact on the indoor and surrounding areas.
Applications
Industrial Manufacturing
Used for powering three-phase motors, production lines, and processing equipment in factories, meeting the requirements for continuous load operation and phase consistency.
Commercial Complexes
Used for backup power systems in shopping malls, office buildings, and mixed-use complexes, providing three-phase power output for elevators, air conditioning, and lighting systems.
Construction Sites
Used for powering tower cranes, hoists, and welding equipment on construction sites, adapting to scenarios with concentrated use of three-phase power equipment.
Hospitals
Used for backup power supply for medical equipment and logistics systems, meeting the requirements for three-phase precision equipment and power quality.
Data Centers Auxiliary Systems
Used for auxiliary power supply and emergency systems in computer rooms, reducing the impact of voltage fluctuations on some three-phase auxiliary equipment.
FAQ
Q: What are the main differences between a three-phase AC power supply and a single-phase AC power supply?
A: A three-phase AC power supply outputs three AC power supplies with a 120° phase difference, which can directly drive industrial three-phase motors; a single-phase AC power supply is only suitable for single-phase loads and requires additional phase conversion.
Q: What is the function of an AVR system?
A: An AVR monitors the output voltage and adjusts the excitation current to maintain the voltage within a set range when the load changes, thereby reducing the impact of voltage fluctuations on equipment operation.
Q: Does the silent structure affect the three-phase output capability?
A: The silent structure only affects noise propagation path control and does not participate in the power output circuit design; therefore, it does not change the three-phase output electrical characteristics.
