In a 3000 square meter shopping mall, reasonable configuration of circuit breakers is the key to ensure the normal operation and safe use of electrical equipment. This article will explore the mall circuit breaker configuration principles, demand analysis, electrical load calculation and other content, in order to guide readers how to scientifically and reasonably configure the circuit breaker, to ensure the electrical system stability and safety of the mall.

1. Configuration principles

1.1 compliance

• circuit breakers are configured to comply with national standards and relevant codes to ensure compliance and safety of the electrical system.

1.2 security

• choose high-quality and reliable circuit breaker equipment to ensure the safety and stability of the electrical equipment in the mall.

1.3 flexibility

• according to the actual needs of the mall and future development planning, the configuration of flexible and adjustable circuit breaker, convenient for future maintenance and expansion.

2. Needs analysis

2.1 mall layout

• regional division of the mall, including retail areas, office areas, toilets, corridors and other different functional areas, each area of the electricity demand is different.

2.2 lighting equipment

• the power demand of the lighting equipment in the mall, and the total lighting load is calculated according to the size and lighting demand of the mall.

2.3 office equipment

• electrical equipment requirements for office areas in the mall, including power requirements for office equipment such as computers, printers, and photocopiers.

3. Electrical load calculation

3.1 lighting load

• calculate the lighting load according to the lighting demand and lamp power of the mall, and configure the corresponding circuit breakers and switches.

3.2 office equipment load

• calculate the power demand of office equipment in each office area in the mall, calculate the total load of office equipment, and configure the corresponding circuit breaker.

3.3 air conditioning equipment load

• the power demand of the air-conditioning equipment in the mall is large, and the load of the air-conditioning equipment shall be calculated according to the power of the air-conditioning equipment, and the corresponding circuit breaker shall be configured.

4. Circuit breaker configuration scheme

4.1 main distribution room

• configure the main distribution room, install the main circuit breaker and main switch, and be responsible for the overall power supply and distribution of the mall.

4.2 branch circuit breaker

• set up corresponding branches according to the electrical load demand of each functional area in the mall. Circuit Breaker power support for different regions.

4.3 safety protection circuit breaker

• configure leakage protection circuit breaker, overload protection circuit breaker and other safety protection devices to ensure the safe operation of the electrical system of the mall.

5. Daily maintenance and inspection

• regularly check the working status of circuit breakers and electrical equipment, and deal with abnormal situations in time to ensure the stable operation of the electrical system of the mall.
• Establish sound electrical equipment files and maintenance records, regularly maintain and maintain the equipment, and extend the service life of the equipment.
