Power transformer body and on-load tap-changer integrated chromatography on-line monitoring device

Abstract

The invention relates to a power transformer body and on-load tap-changer integrated chromatography online monitoring device which is arranged in a stainless steel shell and comprises a transformer body chromatography detection assembly, an on-load tap-changer chromatography detection assembly, a micro-processing assembly and a power module. During monitoring, oil-gas separation is carried out on an oil sample in the transformer body or on-load tap-changer chromatographic detection assembly through the oil-gas separation module, separated gas components are detected through the gas detection module, then the oil sample is filtered through the filtering module and then input into the transformer body and the on-load tap-changer, and whole oil circulation is achieved; and then a data processing module in the micro-processing assembly is used for carrying out optimization processing on the signals, and finally data is transmitted to a cloud platform through a data transmission module. The device adopts a stainless steel shell, has the advantages of strong anti-interference capability and strong corrosion resistance, and meanwhile, the Internet of Things technology is used for accessing data to a cloud platform, so that the target of monitoring the running state in real time is realized.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of power transformers and on-load tap-changers, in particular to an integrated chromatographic on-line monitoring device of a power transformer body and on-load tap-changers. Background technique [0002] With the development of China's economy, electric energy has become a necessity for the development of all walks of life. Ensuring the safety and stability of electric energy is a key issue in today's power system, and power transformers are extremely important equipment in power equipment, and the reliability of their operation is directly related to the safety and stability of the entire power system. The on-load tap-changing transformer is an important power transmission and distribution equipment in the power system substation. It realizes the on-load voltage regulation of the high-voltage transmission and distribution grid through the step-by-step action of the on-load tap changer...
