Embodiment Construction

[0031] Such as Figure 1-3 As shown, the monitoring method of the transformer overheating fault, the monitoring method includes the following steps:

[0032] A. Thermal image collection: non-contact monitoring of transformer prone to failure areas, collecting transformer thermal imaging images in the monitoring area, and then transmitting them to the industrial computer; B, image recognition processing: the industrial computer will collect the transformer thermal imaging images Carry out identification and processing to determine whether there is an overheating fault in the transformer; C. Fault judgment and treatment: If the monitored transformer does not have an overheating fault, continue monitoring; if the monitored transformer has an overheating fault, an alarm signal will be sent. The transformer is a high-voltage product, and the invention adopts a non-contact monitoring method to ensure the safety of personnel. The fault-prone area of ​​the transformer in the present ...

Abstract

The invention belongs to the technical field of electrical equipment monitoring and relates to a monitoring method and a monitoring system for an overheat fault of a transformer. The technical problems that traditional monitoring methods and monitoring systems in the prior art are not reasonable enough and the like are solved by the invention. The monitoring system comprises the following steps: A, thermal image acquisition; B, image recognition processing; and C, fault diagnosis and processing. The monitoring method and the monitoring system for the overheat fault of the transformer have the advantages that acquired image information is recognized by adopting a non-contact monitoring mode to realize fast recognition and diagnose of the part, the degree the type of the early potential fault of the transformer. The monitoring method and the monitoring system for the overheat fault of the transformer have the characteristics that the safety, the reliability and the efficiency are high. Meanwhile, by utilizing the non-contact monitoring mode, a condition is provided for realizing all-weather state monitoring on the transformer on the premise that the operation of the transformer is not influenced, and therefore, the safe, stable and reliable operation of equipment is ensured, the maintenance level of the transformer is comprehensively promoted, and the maintenance cost is reduced. The system is reasonable in design, simple in structure, good in working stability and high in fault detection rate.

Description

technical field [0001] The invention belongs to the technical field of power equipment monitoring, and relates to transformer monitoring, in particular to a monitoring method and a monitoring system for a transformer overheating fault. Background technique [0002] Since its birth, the power system has always been in the evolution process of continuous technological innovation. At present, due to the continuous growth of electricity demand and the rise of electricity costs; the increasing pressure of national environmental protection; the continuous introduction of electricity-related technologies and standards, the country has higher and higher requirements for the safety, stability and economy of the power system. The system is facing more and more challenges. Today, when the global environmental situation urgently needs to be improved and new energy development continues to develop, in order to achieve sustainable development, increase the proportion of renewable energy ...
