Automatic Transfer Switch (ATS) 150A-4000A

1. 

   1. Functions of the Automatic Transfer Switch (ATS):

• Ensuring continuous power supply:

  • When the main power source (grid power) encounters a problem (power outage, voltage drop, overvoltage, unstable frequency), the ATS will automatically switch to a backup power source (generator or other power source) in a very short time.

  • This ensures that critical loads continue to be supplied with electricity, avoiding operational interruptions.

• Automatic power transfer:

  • The ATS operates fully automatically without human intervention.

  • When the main power source returns to normal, the ATS will automatically switch back to the main source.

• Equipment protection:

  • ATs are usually integrated with protective devices to ensure the safety of both the power system and electrical equipment.

  • Protective functions typically include: overload protection, short-circuit protection, overvoltage protection, undervoltage protection.

• Increased reliability:

  • The ATS increases the reliability of the power system, ensuring that critical operations are not interrupted by power outages.

  • Especially important for applications such as: data centers, hospitals, manufacturing plants, high-rise buildings, etc.

• Energy management:

  • The ATS can be combined with energy management systems to optimize electricity use.

  • Appropriate power sources can be selected to minimize electricity costs.

2. How to Use the Automatic Transfer Switch (ATS):

• Installation:

  • Install the ATS in a dry, cool, and easily maintainable and inspectable location.

  • Ensure that the ATS is properly grounded for safety.

  • Select switching and protective devices appropriate for the rated current of the switchgear.

• Wiring:

  • Connect the main power source to the main power input terminals.

  • Connect the backup power source to the backup power input terminals.

  • Connect the loads to the output terminals of the ATS.

  • Thoroughly check all electrical connections before energizing.

• Parameter setting:

  • Set parameters such as voltage, frequency, switching time, and protection thresholds.

  • Adjust these parameters to suit the system requirements.

  • Buttons on the switchgear or software can be used for setting.

• Operation:

  • Power the ATS.

  • Test the ATS operation by simulating a power failure.

  • Monitor indicator lights and display parameters to understand the operating status.

  • The ATS can be operated in automatic or manual mode.

• Maintenance:

  • Periodically check switching devices, connectors, and internal components.

  • Clean the ATS to ensure stable operation.

  • Replace damaged components.

    

3. Basic structure of ATS:

• Cabinet: Usually made of steel, powder coated, with impact resistance and rust resistance.

• Controller: Microprocessor, relays, electronic circuits.

• Switching devices: Contactors, circuit breakers, circuit breakers.

• Protective devices: Circuit breakers, fuses, protective relays.

• Display: Displays operating parameters.

• Indicator lights: Indicate operating status.

• Connectors: Connect power, load, and control signals.

• Other accessories: Push buttons, wires, cable trays, etc.

4. Common types of ATS:

• Contactor ATS: Switching with contactors.

• ACB (Air Circuit Breaker) ATS: Switching with ACB.

• MCCB (Molded Case Circuit Breaker) ATS: Switching with MCCB.

• ATS with manual control mode: Allows users to switch manually if necessary.

• ATS with fully automatic control mode: Fully automatic switching, without human intervention.

5. Notes when using:

• Select suitable ATS: Select an ATS with a rated current suitable for the total power of the loads.

• Follow instructions: Carefully read the manufacturer's instructions.

• Electrical safety: Ensure electrical safety during installation, operation, and maintenance.

• Regular inspection: Regularly check the operation of the ATS to detect and promptly handle any problems.

• Regular maintenance: Regular maintenance to ensure the ATS operates stably and durably.
