[0002] An oil-immersed transformer is a power transformer whose main body is installed in a welded steel tank filled with insulating oil. During operation, it generates a lot of heat, which needs to be dissipated through a cooling system. The cooling system uses oil as a cooling medium, but in order to ensure the normal operation of the cooling system and prevent equipment failures caused by cooling medium problems, it is necessary to sample and test these liquids, such as checking their insulation properties, acid value, moisture content, etc.

[0003] When faced with different analytical experiments, multiple and varying numbers of experimental samples are required. However, traditional sampling and analysis devices cannot flexibly adapt to the different needs of different experiments. It is necessary to interrupt the sampling process to replace sampling containers of different specifications and quantities for sample collection. This collection method is not only cumbersome to operate, but may also cause contamination to the samples and affect the accuracy of the experiment.

[0010] Furthermore, the sampling bag is provided with a scale for measuring the sampling capacity.

[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] Embodiment: An electrical engineering automated sampling and analysis device, such as Figure 1-Figure 4As shown, it includes a drawstring 1, a fixing bolt 2, a water pump 3, a liquid extraction tube 5, a delivery hose 6, a splicing tube 7, a connecting hose 9 and a sampling bag 10. The top of the water pump 3 is fixedly connected with the fixing bolt 2, the fixing bolt 2 is fixedly connected with the drawstring 1, the liquid extraction end of the water pump 3 is fixedly connected with the liquid extraction tube 5, the infusion end of the water pump 3 is fixedly connected with the delivery hose 6, a plurality of splicing tubes 7 are movably provided at one end of the delivery hose 6 away from the water pump 3, a connecting hose 9 is fixedly connected to the splicing tube 7, and a sampling bag 10 is movably connected to one end of the connecting hose 9 away from the splicing tube 7. A sealing cover is provided at one end of the splicing tube 7 away from the delivery hose 6, wherein a threaded groove 701 is provided at one end of the splicing tube 7, and a connecting piece 702 is provided at one end of the splicing tube 7 away from the threaded groove 701, the threaded groove 701 and the connecting piece 702 correspond to each other, and a plurality of splicing tubes 7 are connected end to end through the threaded groove 701 and the connecting piece 702, the splicing tube 7 and the delivery hose 6 are connected to each other, the water pump 3 is started, the water pump 3 draws liquid from the liquid extraction tube 5, and discharges it from the infusion end of the water pump 3, and then the liquid flows into the splicing tube 7 through the connected delivery hose 6.

[0022] like Figure 1 As shown, the water pump 3 is connected to a filter screen 4 near the liquid extraction pipe 5 by fixing screws. Here, the design of the filter screen 4 can filter particulate impurities that may exist in the cooling oil, prevent the particulate impurities from entering the water pump 3 through the liquid extraction pipe 5, avoid clogging of the liquid extraction end of the water pump 3, and prevent the water pump 3 from malfunctioning.

[0023] like Figure 3-Figure 4 As shown, a valve 8 for controlling the on-off of the connecting hose 9 is provided on the connecting hose 9. Here, the design of the valve 8 can facilitate the user to control the on-off of the connecting hose 9 according to actual needs, thereby intercepting the cooling oil delivered by the water pump 3 to prevent the sampling bag 10 from excessive collection, and facilitate the user to directly take the sample in the sampling bag 10, thereby improving the flexibility of the device.

[0024] like Figure 4 As shown, the sampling bag 10 is provided with a scale 1001 for measuring the sampling capacity.

Here, when the splicing tube 7 is connected to the delivery hose 6 or when the splicing tube 7 is connected to the splicing tube 7, the sealing gasket 11 can seal the connection gap between the two to prevent sample leakage during the sampling process.

[0026] The device is used for sampling and analyzing the cooling oil of the oil-immersed transformer. When in use, a splicing tube 7 is installed according to the experimental requirements, so that multiple splicing tubes 7 are connected end to end through the cooperation between the thread groove 701 and the connecting piece 702, and then the corresponding sampling bag 10 is installed at the connecting hose 9 connected to the splicing tube 7, so that the sampling bag 10 is connected to the splicing tube 7 through the connecting hose 9. After completion, the oil tank of the oil-immersed transformer is opened, and then the water pump 3 is sent to the inside of the oil tank through the pull rope 1 until it is immersed in the cooling oil with the water pump 3, and then it is started. Water pump 3, water pump 3 draws the cooling oil in the oil tank from the extraction pipe 5, and discharges the drawn cooling oil from the infusion end, so that the cooling oil enters the inside of the delivery hose 6, and is transported to the splicing tube 7 through the guiding effect of the delivery hose 6, and then the cooling oil in the splicing tube 7 enters the sampling bag 10 through the connecting hose 9, until the sampling bag 10 receives a sufficient amount of cooling oil, the water pump 3 is turned off, and the water pump 3 no longer draws the cooling oil in the oil tank of the oil-immersed transformer, and the sampling of the cooling oil is completed, and then it can be moved to the laboratory for analysis experiments.
