Abstract
A kind of dielectric oil chromatographic analysis sampling device, the utility model is made up of syringe, fixed clip, quantitatively fastener, antislip ring.The utility model is applicable to get calibrating gas and nitrogen in dielectric oil chromatographic analysis, there is safety, improve test accuracy, advantage that reliability is high, and can prevent piston after getting gas from getting tolerance change because Gravitational sliding causes, ensure that the precision of getting tolerance.
Description
Technical field
The utility model belongs to transformer technology and dielectric oil chromatographic analysis sampling device structure, mainly the proportioning device structure technology neighborhood of transformer insulated oil chromatogram analysis sampling device.
Background technology
Power transformer is in day-to-day operation process, insulating oil can produce by highfield, electromagnetic environment and various external environment condition effect the gas be dissolved in insulating oil, with the component concentration of characteristic gas in gas chromatography determination insulating oil, that power supplying and generating enterprises judges whether operating oil-filled power equipment exists the faults such as overheated, the electric discharge of latency, to ensure the effective means that power grid security effectively runs.Need from gas cylinder, get 5mL nitrogen in stratographic analysis test and inject 40mL insulation oil sample, and 0.5mL calibrating gas carries out standard specimen correction.The device getting gas at present directly adopts syringe, and testing crew hand props up piston, avoids ejecting under gases at high pressure acting force.This gas mode of getting can bring certain interference because of the difference of the operation technique of individual and Grasping level to the analysis of test findings.Particularly air inflow number very easily affect the result of chromatography test, and oil chromatogram analysis test now still relies on testing crew and relies on individual judgement, experiential operating etc. to be carried out, and can cause the mistake analysis to oil-filled equipment operation conditions.If getting the person of making angry may cause gases at high pressure pushing syringe piston because of carelessness simultaneously, piston is gone out and is injured people by a crashing object, causes personal injury.
Summary of the invention
The purpose of this utility model is got gas and intake method to solve conventional insulator oil chromatography analysis of experiments syringe to get tolerance inaccurate just, test findings is impacted and provides a kind of safe and reliable, can quantitatively, the stratographic analysis sampling device that prevents piston from falling.
The purpose of this utility model is achieved by the following technical solution.
A kind of dielectric oil chromatographic analysis sampling device, the utility model is characterised in that, is made up of syringe, fixing chuck, quantitatively kelly, antislip ring; Fixing chuck is used for fixing syringe, fixing chuck comprise fixing chuck, in fix chuck, lower fixing chuck; Chuck is fixed, in mesopore that lower fixing chuck is offered during syringe assigns into; Be provided with anti-skidding O-ring seal overlap on the injector and fix between chuck, lower fixing chuck in being installed on; Adopt 2-3 root two ends attack threaded quantitative kelly be each passed through upper fixing chuck, in fix chuck, through hole that lower fixing chuck is offered on arc-shaped edges, and two ends adopt nut to be fixed.
The utility model syringe adopts steel piston syringe, and whole fixed clip adopts acrylic material, and quantitative kelly adopts brass material, and anti-skidding O-ring seal adopts O type rubber seal.
The utility model syringe can better bear anticyclonic impact, and piston not easily crashes, and fixed clip adopts easily processing, transparency to reach 92%, the acrylic material that acid-proof alkaline is good.Quantitative fastener adopts plasticity strong, the high and low-cost brass just material of intensity, and can dismantle flexibly.The utility model adopts O type rubber seal to be installed in lower fixed clip, effectively prevents piston from gliding.
The beneficial effects of the utility model are, are applicable to get nitrogen and gas in the chromatography test of substation transformer insulating oil, and have safe and reliable, steadiness is good, can quantitative advantage, and can prevent piston from gliding, ensure to get the little advantage of tolerance error.
The utility model content is set forth further below in conjunction with drawings and the specific embodiments.
Accompanying drawing explanation
Fig. 1 is the utility model one-piece construction and example operating diagram.
Embodiment
As Fig. 1, a kind of dielectric oil chromatographic analysis sampling device, the utility model is characterised in that, is made up of syringe, fixing chuck, quantitatively kelly, antislip ring; Fixing chuck 2 for fixing syringe 1, fixing chuck 2 comprise fixing chuck 5, in fix chuck 7, lower fixing chuck 6; Chuck 7 is fixed, in mesopore that lower fixing chuck 6 is offered during syringe 1 assigns into; Be provided with anti-skidding O-ring seal 4 to be enclosed within syringe 1 and to fix between chuck 7, lower fixing chuck 6 in being installed on; And lower fixing chuck 6 fixes the thick disk of chuck 7 in a Thickness Ratio, mainly play the fixing effect reliably of safety, ensure the anti-buffer action of sampling device, not easily cause the operation of glass syringe fragmentation, ensure precision and the accuracy of sample size simultaneously.
Adopt 2-3 root two ends attack threaded quantitative kelly 3 be each passed through upper fixing chuck 5, in fix chuck 7, through hole that lower fixing chuck 6 is offered on arc-shaped edges, and two ends adopt nut to be fixed, make it have good stability, can be quantitative advantage.
The utility model syringe 1 adopts steel piston syringe, and whole fixed clip 2 adopts acrylic material, and quantitative kelly 3 adopts brass material, and anti-skidding O-ring seal 4 adopts O type rubber seal, effectively can prevent piston from gliding and cause taken amount inaccurate.
Power transformer is in day-to-day operation process, insulating oil can produce by highfield, electromagnetic environment and various external environment condition effect the gas be dissolved in insulating oil, with the component concentration of characteristic gas in gas chromatography determination insulating oil, that power supplying and generating enterprises judges whether operating oil-filled power equipment exists the faults such as overheated, the electric discharge of latency, to ensure the effective means that power grid security effectively runs.Need from gas cylinder, get 5mL nitrogen in stratographic analysis test and inject 40mL insulation oil sample, and 0.5mL calibrating gas carries out standard specimen correction.
The utility model method for making is:
1, the utility model needs the steel piston syringe of use and O type rubber seal all can directly buy.Syringe 1, fixed clip 2, quantitatively kelly 3, anti-skidding O-ring seal 4 all can carry out assembly and disassembly, and by adopting diameter to be 4mm, length is that the brass of 40cm is processed, and has produced and can facilitate quantitative fastener.Meanwhile, purchase acrylic material, and according to design size, die sinking has been carried out to acrylic, then processed according to quantitative fastener size, folder has punched the good combination meeting folder and fastener.
2, the utility model can not slide because of gravity to meet syringe piston, and mounting O-shaped O-ring seal in lower fixed clip effectively prevents piston from gliding.
