17章变压器和相关电路的过载保护问题

请教大家,电池充电器做17章Overload protection of transformers and associated circuits实验,是直接给变压器次级rectifier之后输出带过载吗?是不是从额定带载到保护为止?新手求前辈们指导

17 Overload protection of transformers and associated circuits
Appliances incorporating circuits supplied from a transformer shall be constructed so that in
the event of short circuits which are likely to occur in normal use, excessive temperatures do
not occur in the transformer or in the circuits associated with the transformer.
NOTE Examples are the short-circuiting of bare or inadequately insulated conductors of accessible circuits
operating at safety extra-low voltage.
Compliance is checked by applying the most unfavourable short circuit or overload which is
likely to occur in normal use, the appliance being supplied with 1,06 times or 0,94 times rated
voltage, whichever is the more unfavourable. Basic insulation is not short circuited.
