Transformer monitoring device based on thermal imaging principle

Abstract

The invention discloses a transformer monitoring device based on a thermal imaging principle. The device comprises a monitoring box, a monitoring mechanism, a closing mechanism and a transformer body. The monitoring mechanism is arranged at the upper end of the interior of the monitoring box, the closing mechanism is arranged on the left wall of the interior of the monitoring box, and the transformer body is arranged in the monitoring box. According to the transformer monitoring device based on the thermal imaging principle, an infrared thermal imaging sensor is installed in the monitoring box, heat generated by a transformer body and overall heat distribution data can be sent to monitoring personnel, a servo motor is started to drive a lead screw to rotate, a movable seat moves left and right along the interior of a movable sliding groove, real-time temperature monitoring can be conveniently carried out on the whole transformer body, multiple infrared thermal imaging sensors do not need to be arranged, cost is saved, and the situation that data of temperature monitoring on the transformer by a traditional temperature sensor is inaccurate is avoided.

Description

technical field [0001] The invention relates to the technical field of transformer monitoring, in particular to a transformer monitoring device based on the thermal imaging principle. Background technique [0002] Due to the existence of black body radiation, any object radiates electromagnetic waves according to the temperature. The part with a wavelength of 2.0 to 1000 microns is called thermal infrared. Thermal infrared imaging images objects through thermal infrared sensitive CCDs, which can reflect the temperature field on the surface of objects. Thermal infrared is widely used in military, industrial, automotive assisted driving, and medical fields. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the monitoring devices of transformers are measured and monitored through temperature sensors, and simple air temperature detection is carried out in the transformer placement area, so as to achieve a monitoring purpose for the temperature generated by the transformer. This method is not accurate and cannot monitor the temperature of the transformer. Overall real-time temperature monitoring
