摘要（英）：

The utility model provides an insulator contamination test device based on an acoustic sensor. The test device comprises an artificial fog chamber, an insulator, a test transformer, an electric heating furnace, an acoustic emission detection device and a monitoring device. The insulator is hanged at the center of the artificial fog chamber. One end of the insulator is connected with the test transformer which is arranged outside the artificial fog chamber through a wall passing bushing. A nozzle is arranged on the wall of the artificial fog chamber. The nozzle is connected with the electric heating furnace which is arranged outside the artificial fog chamber. The acoustic emission detection device is arranged in the artificial fog chamber, and comprises a reflector and an electret sensor. The electret sensor is arranged on the focus of a paraboloid formed by the reflector. The receiving end of the electret sensor points to the insulator. The monitoring device is arranged outside the artificial fog chamber. The insulator contamination test device provided by the utility model has the advantages of simple structure and less test process operation.
