Detection device of transformer and liftable transformer perambulating instrument

The invention provides a detection device of a transformer and a liftable transformer perambulating instrument. The detection device comprises a temperature sensor, a foreign matter detection sensor and a controller, the temperature sensor detects current temperature of the top of the transformer, the foreign matter detection sensor detects whether foreign matters exist at the top of the transformer or not, and the controller is used for comparing the current temperature with preset temperature, controlling an alarm to give an alarm if the current temperature is higher than the preset temperature and sending foreign matter information to a client side to enable the same to display the foreign matter information; the liftable transformer perambulating instrument comprises the detection device of the transformer, the detection device is arranged on a support which is fixedly mounted on a lifting mechanism through a connection device, the lifting mechanism is connected with a driving mechanism through a fixing s
