Description

Technical Field

[0001] The invention relates to the technical field of overheat monitoring devices, and in particular to a transformer local overheat monitoring device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. The main function of the transformer is to convert AC voltage, current, and impedance. It uses the principle of electromagnetic induction to convert AC power of one voltage level into AC power of another voltage level of the same frequency. The transformer can be used to increase or decrease voltage, and adjust the voltage level as needed. In addition, the transformer also has an isolation function, which can prevent the other side from being affected when the primary or secondary side fails, thus achieving a safe isolation effect.

[0003] The existing utility model patent with the publication number "CN221803174U" is named a transformer local overheating monitoring device, which relates to the field of glass processing technology, including a base, a transformer is arranged on the upper surface of the base, a bad plate is movably arranged in the base, a rotating sleeve is rotatably installed in the annular plate through a bearing, a bracket is fixedly installed in the rotating sleeve, and a temperature sensor is movably arranged on the upper surface of the bracket. In the utility model, the staff controls the rotation of the rotating sleeve and the movement of the annular plate to move the temperature sensor to any position of the transformer. After the temperature sensor moves to the working position, the staff controls the temperature sensor to move along the bracket so that the contact of the temperature sensor contacts the surface of the transformer, thereby obtaining monitoring data. The monitoring result has a high accuracy, avoiding the occurrence of large errors in the monitoring data. The inventor believes that the staff controls the temperature sensor to move along the bracket so that the contact of the temperature sensor contacts the surface of the transformer, thereby obtaining monitoring data. The monitoring result has high accuracy and avoids the occurrence of large errors in the monitoring data. However, there are certain defects. When performing local monitoring of the transformer, it is necessary to change the position of the monitoring camera. However, the existing monitoring method usually drives the camera to move in a circle. Due to the different shapes and widths of the transformers, this causes the camera to monitor at a distance sometimes and at a close distance sometimes, making it difficult to take a clear picture. At the same time, when the camera monitors, the angle is fixed, which results in a limited monitoring range. In order to solve the above problems, a transformer local overheating monitoring device is needed. Summary of the invention
