摘要（英）：

The utility model provides a transformer internal discharge trouble analogue test device based on signal acquisition discharges comprises the return circuit unit that discharges, acoustical signal monitor cell, auxiliary unit, it the return circuit unit that discharges contains isolation transformer, voltage regulator, testing transformer, divider, protection resistance, box, top cap, simulation discharge electrode, acoustical signal monitor cell contains acoustic sensor, recording device, the auxiliary unit contains heater and oil temperature thermometer, and the heater is placed inside the box, and oil temperature thermometer lower extreme soaks in transformer oil. Upper and lower electrode structure, electrode distance, the discharge path of the removable difference of simulation discharge electrode for discharge and the creeping discharge in the clearance of simulating under the different parameters, acoustic sensor is favorable to reducing the external interference for placing in the inside built -in sensor of box, accurate acoustics signal when the acquisition trouble is discharged.
