The usage conditions of low and high voltage distribution cabinets are crucial for ensuring the normal operation of the power system and the long-term safety of the equipment. The following are the usage conditions for low and high voltage distribution cabinets:

1. Environmental Conditions:

1. Temperature: Distribution cabinets generally require operation in an environment between -5℃ and +40℃, while some high-end equipment may have specific requirements within a narrower temperature range.

2. Humidity: The environmental humidity should be kept below 90% to avoid short circuits or corrosion due to moisture.

3. Air Quality: It should be kept away from chemically corrosive gases and dust to prevent damage to the equipment.

2. Electrical Conditions:

1. Power Quality: The power supply to the distribution cabinet should meet its specifications, and the voltage fluctuation range should be within the allowable range of the equipment.

2. Load Capacity: The distribution cabinet should be able to carry loads within its design range to avoid overload operation.

3. Installation Conditions:

1. Foundation: It should be installed on a flat, non-vibrating, and non-corrosive foundation or floor.

2. Protection: Depending on the usage environment and requirements, the distribution cabinet should have appropriate protective measures, such as waterproof, dustproof, and fireproof.

3. Space Requirements: There should be enough space around the distribution cabinet for maintenance and operation.

4. Operation and Maintenance Conditions:

1. Operators: Operators should have the relevant electrical knowledge and be familiar with the equipment operation and maintenance processes.

2. Regular Inspections: The distribution cabinet should be regularly maintained and inspected to ensure it is in good working condition.

3. Fault Handling: If a fault or abnormal situation is found, use should be stopped immediately, and relevant personnel should be contacted for repairs.

5. Safety Conditions:

1. Insulation Performance: The insulation performance of the distribution cabinet should meet relevant standards to avoid leakage risks.

2. Safety Protection Devices: There should be complete safety protection devices, such as grounding protection and leakage protection.

3. Safety Warning Labels: There should be clear safety warning labels and operation guidelines on the distribution cabinet.

In summary, the usage conditions of low and high voltage distribution cabinets cover various aspects including environment, electrical, installation, operation and maintenance, and safety. In practical applications, users need to strictly adhere to these conditions based on specific situations to ensure the normal operation of the distribution cabinet and the safety of personnel. For any questions or uncertainties, it is recommended to consult professionals for further guidance.
