Embodiment Construction

[0015] The implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0016] An eluting device for gas chromatographic analysis of transformer insulating oil, such as figure 1 with 2 As shown, it includes a cylindrical metal elution body 4 with an upper end opening. The upper opening of the elution body is screwed with an upper cap 1 on the elution body, and the lower half of the cylindrical inner space of the elution body is filled with Packing 10, the upper half of which is the eluting gas space 6, and an upper air inlet and outlet 5 communicating with the inner space is formed on the upper top surface of the upper cap, which is used for the outlet of oil-soluble gas and eluting gas and the inlet of back-blowing gas , the lower bottom surface of the elution body is formed with...

Abstract

The invention relates to an eluting device for the insulating oil-gas chromatographic analysis of a transformer. The eluting device comprises a cylindrical metal eluting body with an opening in the upper end, wherein an upper sealing cap covers the upper end of the eluting body through a thread in a screwing manner, the lower-half part of the inner space of the eluting body is filled with a filler, the upper-half part of the inner space of the eluting body serves as an eluting gas space, an upper gas inlet and outlet hole is formed in the top surface of the upper sealing cap, a lower gas inlet and outlet hole is formed in the lower bottom surface of the eluting body, a vertically-downward heating rod hole is formed in the top of the right side wall of the eluting body, a vertically-downward temperature measuring hole is formed in the top of the left side wall of the eluting body, a heating rod corresponding hole corresponding to the heating rod hole and a temperature measuring corresponding hole corresponding to the temperature measuring hole are formed in a top cover of the upper sealing cap. The eluting device is simple and reliable in structure; and the operation time of an analyst is greatly saved, and the degassing rate is far higher than that of a standard requirement.

Description

technical field [0001] The invention belongs to the technical field of insulating oil gas chromatographic analysis, in particular to an eluting device used for transformer insulating oil gas chromatographic analysis. Background technique [0002] At present, elution technology is mainly used in the fields of biotechnology, preparation of chemical reagents, liquid chromatography analysis, and medical and health equipment, and is mainly used for the separation of mixtures or further separation of difficult-to-separate substances. There is no dedicated gas elution device on the market, and they are all used in conjunction with analytical instruments, and the purpose of elution is also different. In order to cooperate with the gas chromatographic analysis technology of insulating oil and achieve complete gas elution, it is necessary to develop an elution device for gas chromatographic analysis of transformer insulating oil. Contents of the invention [0003] The purpose of th...
