Transformer secondary circuit fault simulation platform

The present invention provides a transformer secondary circuit fault simulation platform. The platform comprises: a three-phase standard source configured to supply a first current; an upflow device configured to increase the first current to a second current, wherein the upflow device is an electromagnetic coupling type, multi-turn coils are arranged at a primary side, and a single coil is arranged at a second side; a current transformer set configured to selectively regulate the second current to a third current, wherein the current transformer set is a multi-transformation ratio transformer; and a state simulation unit configured to simulate the normal connection, open circuit, terminal short connection, a serial connection rectifier and a primary bypass state of a secondary circuit, wherein the current output end of the current transformer set is connected with a secondary circuit inspecting instrument to be tested through the state simulation unit.
