Embodiment Construction

[0024] The present invention will be described in more detail below in conjunction with examples.

[0025] Best practice:

[0026] a kind of like figure 1 The full degassing system and degassing process of the chromatographic high-performance full-analysis online monitoring device for transformers shown. Including oil filter oil return system 1, online gas content detection system 2. The oil filtering and returning oil system includes an oil circuit circulation system 11, a degassing tank 12, an agitator 13, and an oil storage tank 14. The agitating member 131 of the agitator extends into the degassing tank, and the oil circuit The circulation system includes a cylinder 111 and a vacuum pump 112. The oil port of the cylinder is connected with the upper and lower oil outlets of the transformer through the oil pipeline. The vacuum pump is connected with the air port of the cylinder through the oil pipeline. It is also connected with the carrier gas system through the oil pipe...

Abstract

The invention relates to a full desaeration system of a chromatogram high-performance total analysis on-line monitoring device and a desaeration process of the full desaeration system. The invention adopts the oil sample quantitiveness for oil path circulation, can calculate the circulation times required by cleaning so as to achieve the cleaning of dead oil of the system; meanwhile, the invention adopts a method which combines direct oil return and oil discharge, thereby fully returning the rest oil sample to a transformer.

Description

technical field [0001] The invention relates to a novel chromatographic on-line monitoring device, in particular to a full degassing system and a degassing process of the insulating oil chromatographic on-line monitoring device suitable for transformers. Background technique [0002] Chromatographic analysis of dissolved gases in insulating oil is an effective method to detect latent faults in oil-filled electrical equipment. With the development of condition-based maintenance of electrical equipment, chromatographic analysis of insulating oil becomes more important, and the detection work will be more arduous. Due to the long off-line chromatographic detection cycle in the laboratory, the power departments of all provinces and cities in the country have carried out online monitoring in recent years, which has played an active and effective role in the safe operation of the main equipment of the power grid. The existing degassing system has disadvantages such as complex stru...
