Transformer detection system

Abstract

The invention discloses a transformer detection system. The system comprises an oil temperature detection unit, a noise detection unit, a current and voltage detection unit, a central processor, an early warning unit and a wireless communication module. The oil temperature detection unit is used for detecting oil temperature in a transformer in real time. The noise detection unit is used for detecting vibration signals and sound signals of the transformer in real time. The current and voltage detection unit is used for detecting high voltage operation voltage, high voltage load current and high voltage end screen current values of the transformer in real time. According to the invention, detection data is transmitted to a monitoring center along with a detection network, so real-time monitoring of the transformer is achieved; different information is combined and integrated to judge faults, so an information fusion effect is achieved; maintenance plans are reduced; defects of blindnessand enforceability are overcome; a large number of manpower and materials are saved; and damage to other aspects of the transformer in the maintenance process is avoided.

Description

technical field [0001] The invention relates to the electrical field, in particular to a transformer detection system. Background technique [0002] my country's power system is moving towards the direction of super (ultra) high voltage, large capacity, and national interconnection. The scale is still expanding, and the number and capacity of transformers are further increased. Against such a background, the requirements for the safety of power generation, power supply and distribution are getting higher and higher. The transformer is one of the most important and valuable electrical equipment in the power system, and its operating status is directly related to the safety and stability of the entire power system. [0003] For a long time, the maintenance strategy of electrical equipment in my country's power system mainly adopts regular maintenance based on time. The planned maintenance system undoubtedly plays a very good role in the diagnosis of electrical equipment fault...

Problems solved by technology

Due to the complex and diverse causes of power transformer faults, it is difficult to meet the fault diagnosis requirements only by a single fault diagnosis method.

Lack of a comprehensive diagnostic method that combines various mature traditional fault diagnosis methods, or takes into account the advantages of each diagnostic method as much as possible
