摘要:供配电系统是整个商场安全、可靠运营的核心部分,是电力系统中对商场用电区域进行电能供应和分配的系统。

    首先,安全性是商业发展中的重要环节,特别是大型商场,由于人员密集、疏散困难、排烟不畅等, 一旦在商场内发生电气火灾, 极容易造成伤亡较多的重大火灾事故, 所以商场建筑的电气设计要特别注重火灾监控及消防措施, 所以合理安排、设计至关重要。

   其次,供电的可靠性是商业的中心支柱,特别是大型商场,一旦商场供电出现问题,整个商场的经济将无法运作,对商场造成重大经济损失,只有保证供电的可靠才能为商家带来很好的社会效益和经济效益。

   本文通过对商场用电负荷的计算和短路电流的计算来选择电气设备,以及确定变电所的主接线方案,加上变电所的继电保护设计和备用电源设计,从而保证了商场供电的可靠性,电气火灾消防联动和防雷接地保证了商场的安全性,所以本设计使得商场供电的可靠性、安全性大大提高了。

ABSTRACT: Supply and distribution system is the entire mall safe, reliable operation of the core part of the power system in the area of shopping malls electricity power supply and distribution system.

    First of all, security is an important part of the commercial development, especially in shopping malls, crowded evacuation difficulties, poor smoke, an electrical fire in the mall, very likely to cause more casualties major fire accident, so the mall building electrical design should pay special attention to the fire control and fire fighting measures, so reasonable arrangement, design is essential.

   Second, the reliability of power supply is a central pillar of the business, especially for large shopping malls, shopping malls supply problems, the economy of the entire mall will not work to cause significant economic losses, the mall, only to ensure reliable power supply in order for businesses to bring good social and economic benefits.

   In this paper, the mall electricity load calculation and short circuit current calculation to select electrical equipment, as well as to determine the main substation wiring scheme, plus substation relay protection design and standby power supply design, thus ensuring the mall supply reliability, electrical fire fire linkage and lightning protection and grounding to ensure the security of the mall, so the design makes the mall reliability of supply, security is greatly improved.

Keywords: shopping malls; supply and distribution system; security; reliability
