[0002] Transformers are a common type of electrical equipment used in power transmission, and are mainly used to transform AC voltage and current to transmit AC power. Oil-immersed transformers require the use of an oil chromatograph to determine the content of dissolved gas components in the insulating oil using gas chromatography, so as to determine whether the transformer in operation has potential overheating, discharge and other faults, in order to ensure the safe and effective operation of the power grid. It is also a necessary means for oil-filled electrical equipment manufacturers to conduct factory inspections on their equipment.

[0003] Patent CN216525613U proposes a transformer oil chromatograph analyzer, which can conveniently put the test sample into the inside of the oil chromatograph analyzer body through a feeding mechanism arranged on the oil chromatograph analyzer body.
