小弟现在手头有个UL多士炉的项目,看标准时有些疑惑,请各位有经验的朋友指点一下!!
标准原文如下:
44.2.5.1 a toaster is to be operated as described in 44.1.5 without toast and with doors, or the equivalent, closed. in the case of an automatic toaster, any means employed for de-energizing the heating elements is to be defeated.
我看了后对any means employed for de-energizing the heating elements is to be defeated.这段话有些疑惑,如果把任何导致发热元件断电的措施或装置都失效的话,那不是将发热线直接和电源连接吗?这样的话持续加热肯定会有危险发生的!我想请教一下有经验的朋友任何导致发热元件断电的措施或装置包括保护装置吗?(比如保护继电器,热断路器,FUSE等等)
