In modern society, electricity is crucial, permeating all aspects of life and production. Whether it's hospitals safeguarding lives, data centers handling vast amounts of information, or factory workshops driving industrial progress, a stable power supply is essential. The Automatic Transfer Switch (ATS) for diesel engines plays a vital role in ensuring uninterrupted power.
The ATS acts as a key link between utility power and diesel generators. In normal operation, it enables utility power to supply electricity smoothly to various electrical equipment. However, when utility power failures occur, like outages, voltage drops, or frequency abnormalities, the ATS springs into action. Its high-precision sensors detect issues swiftly, and it promptly starts the diesel generator and switches to backup power, ensuring minimal disruption to electrical equipment. Once the utility power is restored, it seamlessly reverts to the normal supply.
For instance, during a typhoon-induced power outage at a city's transportation hub, the ATS system reacted within 50 milliseconds, allowing the station's lighting, security, and display systems to keep running, averting passenger chaos and ensuring smooth operations.
Intelligent MonitoringAdvanced sensors sample utility power parameters like voltage, current, and frequency multiple times per second. They're highly sensitive, detecting even slight fluctuations, such as a 2% voltage deviation.Intelligent algorithms analyze collected data, combining it with historical power and local meteorological info to predict potential power risks. Before a thunderstorm, for example, the diesel generator can be preheated in anticipation of possible voltage drops.
Hierarchical ResponseFirst-Level Response: The moment utility power loss is detected, the ATS cuts off non-essential loads like landscape lighting and some office equipment to reduce power consumption and secure power for critical loads, buying time for the generator startup.Second-Level Response: Within 0.2 seconds, it initiates the diesel generator's pre-magnetization process, adjusting the output voltage and frequency to match the load, keeping the phase difference within ≤15°.Third-Level Response: In 0.5 seconds, via reliable actuators and advanced arc-free contact technology, it switches the power source, protecting equipment from arc damage and ensuring a smooth transition to the generator's power.
Stable RegulationDifferent scenarios demand varying voltage stabilities. Hospital CT scanners require voltage fluctuations within ±2%, while some factory machinery can tolerate ±5%. The ATS regulates output voltage based on load characteristics.When power is tight, the ATS dynamically allocates load. In hospitals, it prioritizes power to operating rooms and ICUs, reducing power to other areas like ward air conditioners.
Intelligent Back-SwitchingWhen utility power recovers, the ATS doesn't switch back immediately. It monitors for about 10 minutes, checking voltage, frequency, etc. Only when the power is stable within set ranges, like 380V ± 5% and 50Hz ± 0.2Hz, does it initiate the switch back.After switching, the diesel generator runs for 3 - 5 minutes to cool down, preventing engine damage and extending its lifespan.
Medical Field Traditionally, power outages in hospitals could halt surgeries and life support equipment, endangering patients. With ATS, in case of utility power failure, it quickly switches to the diesel generator, ensuring power to critical areas and allowing surgeries to continue, averting medical disasters.
Data Centers Data centers house vast enterprise and user data. A brief power outage can lead to server downtime and data loss, costing enterprises dearly. The ATS's rapid switching keeps servers running and data intact during utility power issues, safeguarding business operations.
Industrial Production In factories, power outages can scrap products in progress and incur high restart costs. The ATS instantly switches power sources, maintaining production line operation, reducing waste, and enhancing productivity.
Capacity MatchingDetermine the ATS's rated current and capacity based on actual power load. Use the formula: Rated Current = Total Load Power (kW) × 1.73 ÷ Voltage (V) × 1.1 (allowing for some redundancy). For a 1000kW small factory with 380V voltage, an approximately 1500A ATS is needed.
Protection RequirementsDifferent scenarios demand different ATS protections. In medical settings, it must meet relevant safety standards, with stable contact materials to prevent interference. In industrial environments with dust, humidity, or hazards, it needs appropriate protection levels like IP54 or above, or explosion-proof certification.
Intelligent FeaturesConsider intelligent functions as technology advances. Some high-end ATSs support Modbus for remote monitoring, allowing ops staff to track equipment status and switching history. For energy-saving needs, choose ATSs with intelligent load regulation.
