What Are The Main Aspects Of The Safety Operation Procedures Of Distribution Cabinets And Distribution Boxes?

1. Preparation before use: The distribution box and switch box should be set up in a well-ventilated and dry place, away from flammable and explosive materials. Check whether there is obvious damage on the chassis before use, and replace or repair it in time if there is damage. Check whether the cable is damaged or aged, and repair or replace it in time.

2. Safety precautions for wiring operation: Before wiring operation, the power supply should be cut off and the power supply should be confirmed to be disconnected. When wiring, the correct wiring operation should be carried out according to the wiring diagram or wiring identification of the equipment, and it is strictly forbidden to connect and move indiscriminately. For equipment with metal enclosures, grounding operations should be carried out to ensure the safety of personnel and equipment.

3. Safety precautions during operation: Do not operate the distribution box and switch box in a humid environment, so as not to cause leakage and short circuit. Do not operate the distribution box and switch box in a high-temperature environment, so as not to cause overheating and damage to the equipment. Attention should be paid to the protection of the equipment during operation to avoid impact or damage.

4. Daily maintenance: check whether the wiring of the switch box and distribution box is loose, and if it is loose, it should be tightened in time 1. Regularly clean the inside and outside of the chassis from dust and maintain good ventilation of the chassis. Regularly check whether the grounding resistance of the equipment is normal, and deal with it in time if there is any abnormality. Regularly check whether the working status of the equipment is normal, and repair it in time if there is any abnormality.

5. Emergency measures: In the event of leakage, cut off the power supply immediately to prevent the current from passing through the personnel to be electrocuted, and isolate the leakage place, and contact professional maintenance personnel for maintenance in time. In the event of a short circuit, immediately cut off the power supply to prevent excessive current from causing damage to the equipment or causing fire, isolate the short-circuited equipment, overhaul the equipment after it cools down, and contact professional maintenance personnel for maintenance in time. In the event of a fire, immediately cut off the power supply, use a fire extinguisher or fire extinguishing appliance to extinguish the fire, and contact the fire department as soon as possible to ensure the safety of personnel.

6. Requirements of operators: Operators should have certain power knowledge and maintenance experience, and understand the basic structure and working principle of distribution cabinets. Operators should be professionally trained and hold relevant certificates. Operators should wear labor protection equipment that meets safety requirements, such as electrically insulating gloves, anti-static shoes, etc. Operators shall abide by the power safety operation specifications and shall not operate without authorization.

Through the above regulations and requirements, the safe use and maintenance of distribution cabinets and distribution boxes can be ensured, and the normal operation of the power system and the safety of personnel can be guaranteed.
