Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that most of the transformers are installed outdoors, and infrared radiation is transmitted in the atmosphere. The outdoor environment is relatively complicated, and solid or liquid suspended particles such as fog and dust in the atmospheric environment have a strong effect on infrared radiation. The attenuation and absorption effect of the infrared temperature measuring device is not accurate, and the infrared detector detects the transformer in a poor timeliness, and cannot give a timely warning when the working temperature of the transformer is too high

Abstract

The invention relates to the technical field of transformers, in particular to a temperature monitoring and early warning system for a transformer, the system comprises a surface temperature sensing assembly arranged on the outer side wall of a transformer body and a controller connected with the surface temperature sensing assembly, and the controller is connected with an alarm; the system also includes a circulating oil tank circularly connected with the interior of the transformer body and a heat exchanger connected with the transformer body, a thermocouple is arranged in the circulating oil tank, and the thermocouple is connected with the controller; a storage module, a timing module and an open circuit protection module are arranged in the controller, and the controller is connected with a circuit breaker which is in control connection with the transformer body. The system has the effects of accurately monitoring the working temperature of the transformer in real time, early warning in time and improving the protection of the transformer body.

Description

technical field [0001] The present application relates to the technical field of transformers, in particular to a temperature monitoring and early warning system for transformers. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage, and is an important part of the power system. When the working temperature of the transformer is too high, the insulation protection of each component is easily decomposed or damaged due to high temperature, and the possibility of transformer failure, fire and explosion is greatly increased. Therefore, when the transformer is used, it is necessary to regularly check the working temperature and the actual condition of the tooling, which is easy to reduce the probability of fire or explosion accidents. [0003] The Chinese patent with the notification number CN203443672U discloses a transformer equipped with an infrared temperature measuring device, including a trans...
