What are the functions of high and low voltage switchgear? How to operate it correctly?

High and low voltage switchgear is an important distribution equipment in the power system, with multiple functions to ensure the safe operation of the power system. The following are its main functions and correct operation guidelines:
Function:
1. Electricity distribution and control:
Electric energy branch: distributes the electrical energy transmitted from the power system to different electricity consuming areas or equipment.
Electric energy control: Control parameters such as current and voltage in the power system to ensure safe operation of the system.

2. Protection function:
Overload protection: When the current exceeds the set value, the circuit is automatically cut off to avoid equipment damage.
Short circuit protection: Quickly cut off the circuit to prevent short circuits and ensure the safety of equipment and personnel.

3. Control and monitoring:

    Remote control: With remote control function, it supports remote switching and monitoring of equipment status.
    Intelligent monitoring: real-time monitoring of equipment operation status, early detection of potential problems and early warning.

4. Security protection:

    Personal safety protection: Equipped with safety devices to avoid injuries due to misuse.
    Fault self-diagnosis: with self-diagnosis function, anticipate and warn of possible faults.

5. Flexibility and reliability:

    Modular design: Modular design makes it easy to assemble, maintain, and upgrade.
    Stable and reliable: The equipment operates stably and reliably, adapting to various operating conditions and load changes.

Correct operation guide:
1. Familiar with equipment:

    Read the product manual and operation manual in detail to understand the functions, characteristics and safety precautions of the equipment.

2. Safe operation:

    Wear safety gear before operation and ensure that the equipment is in a stop state.
    Abide by the operating procedures and strictly prohibit overload operation or unauthorized personnel.

3. Start correctly:

    Check the external and internal status of the device to ensure that there are no abnormal conditions before starting the device.
    Follow the steps in the operating manual to start the equipment gradually to avoid sudden high load.

4. Pay attention to monitoring:

    Regularly check the operating status and parameters of the equipment to maintain its normal operation.
    Pay attention to abnormal sounds, vibrations, or temperature increases, and deal with them in a timely manner.

5. Emergency response:

    In case of malfunction or abnormality, immediately cut off the power supply and notify professional maintenance personnel to deal with it.
    Do not disassemble or repair equipment without authorization to avoid causing greater damage.

Conclusion:

The functions of high and low voltage complete sets of switchgear are rich and diverse, providing an important guarantee for the safe and stable operation of the power system. Correct operation of high and low voltage complete sets of switchgear is the key to ensure the normal operation of equipment and personnel safety. Strict compliance with operating procedures and safety precautions is required. Familiarity with equipment functions, keeping equipment clean, regular maintenance inspections and timely handling of abnormal situations are all key steps for correct operation.
