Experimental device for simulating electrical faults

The utility model provides an experimental device for simulating an electrical fault. Box body, a smoke exhaust pipeline switch is arranged at the top of the box body; the box body is connected with asmoke exhaust pipeline through a smoke exhaust pipeline switch; a real-time smoke analyzer is arranged in the smoke exhaust pipeline, the smoke exhaust pipeline is connected with an electric precipitator and a smoke purifying device, and a variable-angle lifting device, a temperature sensor, a pressure sensor, a smoke collecting device, a liquid carbon dioxide spraying head, a combustion sample tray and a combustion sample heating device are arranged in the box body. According to the utility model, an electrical fault can be simulated or preparation of an electrical fault caused by a fire disaster can be simulated by using a liquid or solid two-phase material; in the preparation process, the environmental pressure and temperature and various smoke components and concentrations during molten bead formation can be
