The utility model discloses a transformer test analogue means, in using, it is connected with needing experimental transformer to pass through termination with the cable, a plurality of sub - cable in the cable respectively with the A looks of the high -pressure side of transformer, the B looks, the A looks of C looks and low tension side, the B looks, C looks one -to -one is connected, the front one -to -one of eight interfaces on the other end of cable and the interface panel is connected, the back of eight interfaces on the interface panel respectively with the 2nd interface panel on the back of eight interfaces pass through the insulated wire one -to -one and be connected, actually be through the utility model provides a A looks of the high -pressure side of transformer test analogue means on with the transformer, B looks, C mutually and the A looks of low tension side, B looks, C through the cable connect draw to get off and can be normal use with the test instrument butt joint, during the test instrument of the experimental usefulness that needs to be changed, as long as on the 2nd interface panel the plug wire can, need not to climb up the transformer, reduce and change wiring time, improve work efficiency.
