A quantitative sampling device for oil sample chromatographic analysis with a dust-proof plug

Abstract

The invention relates to a chromatographic analysis and quantitative sample injection device with a dustproof plug for an oil sample. The chromatographic analysis and quantitative sample injection device comprises a supporting rod arranged on a bracket, and a movable block, a pressing assembly and a sample injection opening plugging assembly arranged on the supporting rod, wherein a longitudinal transmission device, a mounting seat for mounting an injector and a clamping device with an effect of fixing the injector are arranged on the movable block; the longitudinal transmission device comprises a longitudinal motor and a transmission gear group thereof; the mounting seat comprises a U-shaped opening and a mounting cavity; the clamping device comprises a fixed seat, a clamping motor, a clamping screw rod, a clamping sliding block, a connection rod and a clamping claw; the pressing assembly comprises a pressing motor connected with the movable block, a pressing screw rod, a guide shaft, a transmission gear group and a pressing sliding block; the sample injection opening plugging assembly comprises a dustproof electromagnetic coil with an inner iron core, a supporting arm and the dustproof plug. The chromatographic analysis and quantitative sample injection device is safe, convenient and accurate in sample injection; the problems of waste of samples, deviation of experimental data and low efficiency are effectively solved; meanwhile, the chromatographic analysis and quantitative sample injection device can be further applied to sampling of the oil sample and is wide in application range and easy to popularize.

Description

technical field [0001] The invention relates to a quantitative sampling device for oil sample chromatographic analysis with a dust-proof plug. Background technique [0002] During the daily operation of power transformers, insulating oil is subjected to strong electric fields, electromagnetic environments, and various external environments to produce gas dissolved in insulating oil. Insulating oil chromatography is a diagnostic technique for condition assessment of oil-filled equipment . It provides effective insulation supervision for electrical equipment to ensure the safe and stable operation of electrical equipment. Specifically, gas chromatography is used to measure the component content of dissolved gas in insulating oil. The measurement results are used by power supply companies to judge whether there are latent overheating, discharge and other faults in the oil-filled power equipment in operation, so as to ensure the safe and effective operation of the power grid.
