The ATS (Automatic Transfer Switch) is a dual-power distribution cabinet designed to automatically switch between primary and backup power sources. Its core function is to rapidly transfer power to the backup system when the primary power fails or experiences voltage anomalies, ensuring uninterrupted supply for critical loads. Widely used in high-reliability power environments such as data centers, hospitals, and industrial production lines, this equipment guarantees reliable energy continuity.
The ATS dual power switchgear cabinet operates primarily through its core components: the power switching switch, control module, and monitoring system.
Here is a detailed description of its key working mechanisms:
A key function of the ATS dual power switchgear cabinet is to enable rapid and reliable switching between the main and backup power sources. Here are the specific steps for the switching process:
Main power monitoring:
The sensor and monitoring system monitor the power supply status of the main power supply in real time (voltage, current, frequency, etc.).
Primary power failure detection:
When the main power supply is interrupted, under-voltage, over-voltage or abnormal frequency, the control module recognizes these abnormal states.
Backup power startup:
The control module immediately activates the backup power source. If the backup is a generator set, it may take a few seconds to start.
Switch to:
The power switching switch quickly switches the load from the main power supply to the backup power supply under the control of the control module.
During the transition, ensure a seamless connection and minimize the impact on the load.
Primary power recovery monitoring:
After the main power supply resumes normal operation, the control module continues monitoring for a period to ensure stable and reliable power supply.
Switch back to the main power source:
After the main power supply is confirmed to be stable, the control module directs the power switch to transfer the load back to the main power supply.
ATS dual power switchgear cabinets typically support both automatic and manual switching modes to accommodate diverse operational scenarios.

The detailed explanation of the ATS dual power switchgear cabinet's fundamental principles demonstrates its vital role in ensuring power system stability and reliability. Whether through automatic or manual switching, this cabinet provides reliable power support during critical moments, guaranteeing uninterrupted power supply for critical loads.
Power switching is a core function of the ATS dual power switchgear cabinet, with key components including the power switching switch and input/output terminals. These components ensure rapid load transfer between the main and backup power sources.
Power switch:
This is a critical component of the ATS distribution cabinet, responsible for physically switching between the main power supply and backup power supply. The power switching switch typically features high reliability and rapid response.
The switch type can be either mechanical or electronic. Mechanical switches switch power through physical contact, while electronic switches use semiconductor components for switching, offering higher switching speed and reduced mechanical wear.
Power input/output terminals:
This part is responsible for the input and output of power, including the main power input terminal, the backup power input terminal and the load output terminal.
The input and output terminals are typically equipped with high-quality terminal blocks and protective devices to ensure stable and secure power transmission.
The control module serves as the central brain of the ATS dual-power distribution cabinet, monitoring power status, determining switching timing, and executing switching commands. It typically comprises the following sub-modules:
Monitor Submodule:
The voltage, current, frequency and other parameters of the main power supply and the backup power supply are monitored in real time.
The accuracy and real-time of data are ensured by the sensor and signal processing circuit.
Logical Decision Submodule:
Set switch conditions and logic, analyze monitoring data, and determine whether to perform a power switch.
For example, when the main power supply voltage drops below the preset threshold, the logic decision sub-module activates the backup power supply.
Execute sub-module:
After the logic decision sub-module issues the switching instruction, the execution sub-module is responsible for activating the power switching switch.
Ensure a swift and reliable transition to minimize power load impact.
The monitoring system serves as the eyes and ears of the ATS dual-power distribution cabinet, providing real-time monitoring of the entire system's operational status, along with visual interfaces and alarm functions.

Ensure operators promptly identify issues and take appropriate measures to prevent prolonged power outages.
The protection device is a key component of the ATS dual-power distribution cabinet, designed to safeguard equipment and loads during system anomalies or failures, preventing damage and accidents caused by power issues.
Overvoltage protector:
When the power supply voltage exceeds the preset threshold, the overvoltage protector will immediately disconnect the circuit to prevent high voltage damage to equipment and loads.
Undervoltage protector:
When the power supply voltage drops below the preset threshold, the undervoltage protector activates the backup power or disconnects the circuit to ensure stable power supply.
Overcurrent protector ：
When the current exceeds the preset threshold, the overcurrent protector will trip the circuit to prevent excessive current from damaging equipment and wiring.
Short-circuit protector:
Detect short-circuit faults in the circuit and quickly disconnect the circuit to prevent fire and equipment damage caused by short-circuit.
Insulation monitoring and warning device ：
The circuit insulation status is monitored in real time, and the circuit is alarm or cut off when the insulation damage or leakage current is found.
