Embodiment Construction

[0015] Attached below Figure 1-3 The present invention will be described in detail.

[0016] refer to figure 1 , the oil chromatographic analysis standard sampler of the present invention is made up of syringe barrel 1, syringe push rod 2, syringe needle 3 and fixed support, wherein fixed support includes fixed plate 4, control plate 5, upper baffle plate 6 and connects above-mentioned three The screw of the plate and the fixing nut, the fixing plate is fixed on the syringe barrel 1, and the top of the syringe push rod 2 is provided with an upper baffle 6. Since the injection port of the chromatograph has a certain pressure, the upper baffle 6 ensures that the syringe push rod 2 will not be ejected under the action of the pressure gas, avoiding the risk of operation failure, the upper baffle 6 and the fixed plate 4 are connected by two screw rods 7, and the upper baffle nut is set on the upper part of the upper baffle 6 for fixing.

[0017] In addition, a control board 5 is...

Abstract

The invention discloses an oil chromatographic analysis standard sample injector. The oil chromatographic analysis standard sample injector comprises an injector barrel, an injector push rod, an injector needle head and a fixed bracket, wherein the fixed bracket comprises a fixed plate, a control plate, an upper baffle plate, and two screw rods and fixed nuts for connecting the fixed plate, the control plate and the upper baffle plate; the fixed plate is fixed on the injector barrel; the top of the injector push rod is provided with the upper baffle plate; the upper baffle plate and the fixed plate are connected through two screw rods; upper baffle plate nuts are arranged on the upper part of the upper baffle plate; the control plate is further arranged between the upper baffle plate and the fixed plate; the control plate penetrates through the screw rods, and the position adjustment and the positioning of the control plate are performed through control plate nuts at the lower part of the control plate.

Description

technical field [0001] The invention relates to an auxiliary tool when using insulating oil chromatographic analysis, in particular to a tool for gas sampling during chromatographic analysis. Background technique [0002] 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. This is also It is a necessary means for oil-filled electrical equipment manufacturers to carry out factory inspection of their equipment. The requirements of GB / T72...
