Zusammenfassung:The utility model discloses a transformation ratio electric bridge calibrating device, including the install bin, being equipped with the transformer of adjustable input voltage and output voltage proportion in the install bin, the front middle part of install bin is equipped with the control handle that is used for the regulating transformer, and knob control transformer's transformation ratio value is 1: 1, 1: 2, 1: 5, 1: 10, 1: 20, 1: 50, 1: 100, 1: 200, 1: 500, 1: 2000, one every clockwise rotation of knob keeps off the position, and the transformation ratio value of transformer increasesa ratio, and one every counter -clockwise turning of knob keeps off the position, and the transformation ratio value of transformer reduces a ratio. This kind of transformation ratio electric bridge calibrating device can once only accomplish the surveying work of a three circuit transformer voltage ratio as required, and the measuring time is short, is favorable to the timely power transmission of equipment. Transformati
