摘　　要：随着汽车制造业的不断发展,人类生活水平的不断提高,市场对汽车的需求量也越来越大。为了更好地实现北京奔驰“节约成本,降本增效”的理念,充分体现“碳达峰、碳中和”的重大历史意义,同时提高员工技术水平,现场更好地测试返修备件,焊装车间技术维护人员决定搭建测试区。根据现场实际需求,低压电气柜的设计成为搭建测试区的重要一环,主要从低压断路器、熔断器、电源线缆规格进行设计并选取,通过需要系数法进行负荷计算,校验低压断路器、低压熔断器整定电流,应用经济电流密度法计算并选取电源线缆规格。电气器件选取后并安装到电气柜中,将低压电气柜用到焊装车间测试区,实现返修备件测试功能。With the continuous development of the automobile manufacturing industry and the continuous improvement of human living standards,the demand for cars in the market is also increasing.In order to better implement the concept of“cost saving,cost reduction,and efficiency enhancement”of Beijing Benz,fully reflecting the significant historical significance of“carbon peaking and carbon neutrality”,meantime improving the technical level of employees and testing repaired spare part onsite,body shop maintenance decides to build master piece.Based on actual on-site requirement,the designing of low-voltage electrical cabinets has become an important part of building master piece,it mainly designs and selects specifications for low-voltage circuit breakers,fuses,and power cables,load calculation through the coefficient of demand method,verify the set current of low-voltage circuit breakers and low-voltage fuses,calculate and select power cable specifications through the economic current density method.After selecting components,the article installs them in the electronic cabinet and applies cabinet to body shop master piece,it achieves the test function of repairing spare parts.
