Low -voltage heavy current temperature -rise tests system suitable for multiloop output

The utility model provides a low -voltage heavy current temperature -rise tests system suitable for multiloop output, it is mainly by the many magnetic circuit of low pressure heavy current, electric flow regulator and annular opening formula iron core triplex, the many magnetic circuit of low pressure heavy current connect in low pressure electric appliances and do the experimental heavy current of low pressure electric appliances input, again by the output of low pressure electric appliances multiloop, concatenate one on each way output circuit of low pressure electric appliances through the manual electric flow regulator who carries out the target electric current and adjust, behind the experimental conductor of annular opening formula iron core on emboliaing output circuit, the manual magnet gap that carries on is adjusted and is restrained loop current, by the experimental power of the many magnetic circuit of low pressure heavy current output 960KVA interchange, realize through electric flow regulator's
