Transformer oil chromatographic detection system and detection method thereof

Abstract

The invention relates to a transformer oil chromatographic detection system and a detection method thereof, comprising a monitoring module, a detection module, a control module, an acquisition and conversion module, a data management module and a data analysis module; wherein, the monitoring module is connected with the detection module, the control module is separately connected with the monitoring module, the detection module and the acquisition and conversion module, the acquisition and conversion module is connected with the detection module, the detection module is connected with the acquisition and conversion module and the data management module in turn, the data management module is connected with the data analysis module and the data analysis module is operated by a user. Aiming to engineering rescue vehicles, the invention applies a self-made source gas, an automatic control function of quantitative oil-taking, a high effect vacuum degassing and an integrated technology of oil-taking, degassing and detection, thus reducing the volume, saving the source and shortening the detection and analysis circle. The invention can be fixed neatly on a car and is suitable to field work for timely discovering the power transformer latent fault and effectively tracking.

Description

technical field [0001] The invention relates to a detection device and method in the technical field of transformers, in particular to a transformer oil chromatography detection system and detection method. Background technique [0002] At present, in the power supply system, the system for effective monitoring and analysis of transformer oil has been widely used. The monitoring system is divided from the analysis method, there are offline system and online system, and the offline system generally adopts a measurement method with high precision. However, the degassing and measurement operations of offline analysis are complicated and difficult for non-professionals to complete; at the same time, due to the limitation of the offline measurement cycle, it is difficult to capture the faults in the transformer operation in time; The transformer carries out oil chromatographic monitoring and analysis. However, its fixed installation on the transformer site determines that the o...

Problems solved by technology

However, the supply and carrying of the gas source is inconvenient, and the technology adopts the incomplete degassing method, which makes the instrument life short, low efficiency, long time, and is easily interfered by external temperature, humidity, pressure, concentration and other factors, making the measurement accuracy not high.
