The invention relates to a rapid conversion device for test wiring of a zero-flux CT secondary electronic module. The rapid conversion device realizes plug abutting joint between the zero-flux CT secondary electronic module and test equipment, and comprises quantity taking terminals, selective switches, a secondary electronic module end plug, a measuring equipment end plug and test wires, wherein one end of each quantity taking terminal is connected with the secondary electronic module end plug through one test wire, and the other end is connected with one selective switch; and the measuring equipment end plug is connected with a wire incoming end of each selective switch through one test wire. The rapid conversion device has the advantages that the defects that the previous zero-flux CT secondary electronic module is complex in test wiring, long in time consumption and prone to damage equipment are overcome, the plug abutting joint between the zero-flux CT secondary electronic module and the test equipment is realized, the repeated wire connecting and disconnecting on a wiring end of tested equipment are avoided, the power outage and wiring alteration are not needed when measuring different parameters, and the required parameters can be measured by just flipping the selective switches on the rapid conversion device.
