description The invention relates to a temperature rise test device of a winding thermometer for a transformer. The temperature rise test device is characterized by mainly comprising a constant temperature groove and a constant current source, wherein the constant temperature groove can simulate the temperature of an oil surface of the transformer and consists of a temperature controller, a thermometer seat, a working cavity and a stirring mechanism; and the constant current source can simulate the output current of a current mutual inductor of the transformer and consists of a transformer, a circuit part, an output control device and an in circuit test (ICT) measuring device. The constant temperature groove and the constant current source are integrated, so the volume and the weight of equipment are greatly reduced, and a worker can operate and carry the temperature rise test device conveniently and the temperature rise device is applicable to industrial application.
