Problems solved by technology

[0004] Although the above-mentioned gas analysis chromatograph has solved the existing problems to a certain extent, there are still certain problems. For example, the end-to-end serial connection between the two chromatographic columns, the gas is separated through the two chromatographic columns in turn. If the chromatographic columns If the column is shorter, the separation effect will be poor. If the chromatographic column is longer, the detection result will be longer, and the packing in the chromatographic column cannot effectively separate the target gas, and the separation and detection effect is limited; the sample gas detection mechanism is set in the sample gas separation In addition to the mechanism, additional heating and heat preservation measures are also required; the sampling method is also relatively complicated, which is not suitable for conventional sampling devices and modes, and the overall device structure is relatively complicated. The system has the disadvantages of poor long-term stability and easy poisoning failure

Embodiment 1

[0041] Such as Figure 1-4 As shown, a gas separation and detection device in insulating oil provided in this embodiment includes a box body 1, a built-in heating furnace 2, a sample gas separation mechanism 3 and a sample gas detection mechanism 4, a sample gas separation mechanism 3 and a sample gas detection mechanism 4 are connected through the air pipe 5, the sample gas separation mechanism 3 includes a three-way splitter 33 and two chromatographic columns-chromatographic column one 31 and chromatographic column two 32, one end of the three-way splitter 33 is connected with the air pipe 5, and the other two The ports are respectively connected with chromatographic column one 31 and chromatographic column two 32, and the two chromatographic columns are wound into a spiral shape, and are connected up and down in parallel on the outer wall of heating furnace 2; sample gas detection mechanism 4 is accommodated in heating furnace 2, and sample gas detection mechanism 4 It incl...

Embodiment 2

[0056] As the second embodiment of the present invention, there is one detection channel 43 in the detection assembly 40, and only one corresponding detection element, and air holes for air flow are provided between the air inlet channel 41, the air outlet channel 42 and the detection channel 43 respectively. Passage one 44, the overall shape between the passages is "Y". Because of the two detection elements in Embodiment 1, the outer layer of the sensitive sensing area of ​​one of the detection elements is coated with an isolation layer, the collected data is only used to correct the deviation caused by the environment and temperature changes on the detection process, the actual working environment 1. The data deviation caused by temperature is extremely small. In order to save costs, there can be only one detection element and one corresponding detection channel. Other content is the same as embodiment one.

Description

technical field [0001] The invention relates to a gas chromatography detection device and detection technology, in particular to a gas separation detection device for analyzing dissolved gas in insulating oil of high-voltage oil-filled electrical equipment. Background technique [0002] Transformer is a very important equipment in the power system, so monitoring the operation status of the transformer is the key to ensure the safe operation of the power grid. Taking the characteristic gas dissolved in transformer oil as the object of transformer fault monitoring, combined with chromatographic detection technology to detect and analyze the change of gas content, so as to judge whether there is a fault and the nature of the fault inside the oil-filled power equipment, it has been proved to be effective in practice One of the means. Separation from transformer oil contains H 2 , CO, CO 2 , N 2 , O 2 、CH 4 、C 2 h 4 、C 2 h 2 、C 2 h 6 etc., among which the diagnosis of...
