The invention discloses a real-time temperature monitoring device for a synchronous motor, which is used for monitoring the internal temperature of the synchronous motor in real time, and comprises a thermal infrared imager, a data line for connecting peripheral equipment and the thermal infrared imager, and an observation port cover for sealing an observation port of the synchronous motor, an observation hole is formed in the observation opening cover, and a lens of the thermal infrared imager is arranged right opposite to the observation hole, so that infrared radiation in the synchronous motor is received through the observation hole, and the infrared radiation is converted into an infrared thermogram to be transmitted to the peripheral through a data line. The temperature of each position in the synchronous motor is monitored through the infrared thermogram, the overtemperature fault of the synchronous motor is avoided, the stable operation of the synchronous motor is ensured, and the smooth production of steel rolling operation and the like is further ensured. In addition, the thermal infrared imager is arranged outside the synchronous motor and is convenient to install and replace.
Description
technical field [0001] The invention relates to the field of electrical technology, more specifically, to a real-time temperature monitoring device for a synchronous motor. Background technique [0002] In the metallurgical industry, large and medium-sized synchronous motors are usually used to drive rolling mills for steel rolling operations. As the key equipment of the production line, the synchronous motor needs to be inspected regularly during equipment shutdown. [0003] During regular inspection, in addition to external inspection, it is also necessary to open the four observation ports on both sides of the motor to check the insulation material inside the motor, the condition of the stator and rotor, etc., to prevent aging of the insulation material, rubbing of the stator and rotor, short circuit between turns, Local iron core damage and other problems can be avoided to avoid the failure of the motor temperature exceeding the normal range at rated load, which will af...
