Abstract：The hidden dangers of electric shock accidents caused by the low installation height of lighting luminaires in underground garage of residential buildings due to floor height control and blind spots in electric shock protection measures are analyzed. The advantages and disadvantages of several electric shock protection measures are analyzed and compared,and it is suggested that the protection switch of distribution circuit of common lighting luminaires should be equipped with miniature circuit breaker with residual current action protection function.

Key words：underground garage of residential buildings;lighting luminaires;installation height of lighting luminaires;electric shock protection;indirect contact fault protection;lighting distribution box;distribution wire length;residual current action protection

摘　要：分析住宅地下车库照明灯具由于层高控制导致安装高度低矮，电击防护措施存在盲区，带来的电击事故隐患问题。分析比较几种电击防护措施的优缺点，建议普通照明灯具配电回路保护开关采用带剩余电流动作保护功能的微型断路器。
