A substation temperature monitoring device comprising: the device comprises a support 1, a power supply 2, an air pump 3, a first pipeline 4, a pipe joint 5, a plurality of second pipelines 6, a first temperature sensor 7 and a second temperature sensor 8. The bracket 1 is fixedly arranged on the outer surface of the equipment to be tested, the power supply 2 is arranged on the bracket 1, and the air pump 3 is fixedly connected to the bracket 1; one end of a first pipeline 4 is communicated with the air pump 3, the other end of the first pipeline 4 extends towards the equipment to be tested, a pipe joint 5 is fixedly arranged at one end of the first pipeline 4 far away from the air pump 3, one end of a second pipeline 6 is communicated with the interior of the equipment to be tested, and the other end of the second pipeline 6 is communicated with the first pipeline 4 through the pipe joint 5; first temperature sensor 7 sets up in first pipeline 4, and second temperature sensor 8 sets up in second pipeline 6, and first temperature sensor 7 and second temperature sensor 8 are supplied power by power 2.

Specifically, when the device is in operation, the air pump 3 pumps air inside the device, and because the second pipeline 6 is provided in plurality, the air pump 3 can pump air at different positions of the device according to the arrangement position of the second pipeline 6, and the pumped air enters the first pipeline 4 through the second pipeline 6 and is finally discharged to the outside. It will be appreciated that the second temperature sensors 8 can measure the local temperature of the apparatus and in this embodiment the exhaust ends of the second ducts 6 are evenly distributed within the apparatus and the temperature measured by the first temperature sensor 7 is the average temperature of the air at the exhaust ports of all the second ducts 6. Therefore, the device realizes the monitoring of the average temperature of the equipment and the local temperatures of different parts through the first temperature sensor 7 and the second temperature sensor 8 respectively. On the other hand, the air pump 3 accelerates the air flow in the equipment while exhausting air, and has the effect of auxiliary heat dissipation. In addition, the device is arranged outside the equipment, the internal space of the equipment is not occupied when the internal temperature of the equipment is measured, the device is far away from the high-temperature environment inside the equipment, the failure rate is reduced, and the service life of the device is prolonged.
