摘　　要：CB级ATSE具有过电流保护和电源转换两大类功能。本文就其两大类功能在电路中的作用进行技术分析,指出CB级ATSE安装在供电系统的不同位置(电源级、配电级、负载级)应注意的问题,选择不当会造成转换故障,引起供电中断。CB级ATSE应用中应注意:①CB级ATSE不宜作为主开关电器;②作为配电保护电器使用时,与下级保护电器间应具有选择性;③作为终端(负载级)使用时,应注意负载性质与使用环境;④MCB派生的CB级ATSE一般仅适用于照明供电线路;⑤CB级ATSE不允许使用到消防泵供电系统。The class CB ATSE is with the functions of over-current protection and power transfer. This article analyses the roles of these two functions when they are applied to the circuit,and points out that improper selection will lead to transferring fault and the power supply interrupted,when the class CB ATSE is installed in the different positions(power level,distribution power level,load level)of the supply system. The following issues are needed to be noticed,i.e.,the class CB ATSE is not suitable as main on-off apparatus;there should have selectivity between upper and lower ATSE when they are used as power distribution apparatus;load characteristic and application environment should be noticed when they are used as terminal apparatus; the class CB ATSE made by MCB is only used to lighting power circuit generally; the class CB ATSE is not permitted to apply in power circuit for fire-fighting pump.
