Description

가스분석용 절연유 채취장치{Picking device of insulating oil for gas analysis} Picking device of insulating oil for gas analysis

본 발명은 가스분석용 절연유 채취장치에 관한 것으로서, 보다 상세하게는 절연유 시료 채취전이나 후에 외부의 공기나 기포 등의 불순물 유입을 방지하고 절연유에 포함된 휘발성 가스성분의 누출을 억제하여 정확한 가스분석이 가능하도록 하며, 실린더를 안전하게 사용할 수 있음과 더불어 채취된 시료를 안정적이고 신속하게 분석할 수 있도록 된 가스분석용 절연유 채취장치에 관한 것이다.The present invention relates to an insulating oil collecting device for gas analysis, and more particularly, to prevent the inflow of impurities such as air or air bubbles before and after sampling the insulating oil and to prevent leakage of volatile gas components contained in the insulating oil for accurate gas analysis. The present invention relates to an insulating oil collecting device for gas analysis, which enables the use of a cylinder and enables the safe use of a cylinder, and enables the sample to be analyzed stably and quickly.

일반적으로, OF(Oil-Filled)케이블은 그 내부에 절연유가 충전되어 이 절연유에 의해 누전 등을 방지하도록 된 전력케이블의 일종이다. 그런데, 이러한 전력케이블에 이상이 발생되면 통상 열을 동반하기 때문에, 이 열에 의해 내부의 절연유 등이 분해되면서 가스가 발생되어 절연유에 용해된다. Generally, OF (Oil-Filled) cable is a kind of power cable that is filled with insulating oil therein to prevent a short circuit. However, when an abnormality occurs in such a power cable, heat is usually accompanied, so that gas is generated and dissolved in the insulating oil by decomposing the insulating oil inside.

그러므로, 케이블의 전력사고 등을 예방하기 위해서는 절연유를 채취하여 이에 포함된 가스의 성분 등을 분석하면, 케이블 내부의 이상징후를 조기에 진단할 수 있어서 세계적으로 널리 이용되고 있다. Therefore, in order to prevent electric power accidents of cables, when insulating oil is collected and the components of the gas contained therein are analyzed, abnormal symptoms in the cables can be diagnosed early, and thus they are widely used worldwide.

따라서, 이와 같이 절연유에 포함된 가스를 정확하게 분석하기 위해서는 케이블로부터 절연유 시료를 채취할 때 절연유 이외에 불순물이 혼입되면 정확한 가스 분석이 이루어지지 않기 때문에, 외부의 불순물이 유입되지 않도록 시료를 채취하는 것은 매우 중요한 과제이다. Therefore, in order to accurately analyze the gas contained in the insulating oil, when the insulating oil sample is taken from the cable, if impurities are mixed in addition to the insulating oil, accurate gas analysis is not performed. It is an important task.

그런데, 종래의 절연유 채취방식은 도 1에서와 같은, 투명 유리로 된 실린더(10)를 이용하여 절연유를 채취하게 된다. 따라서, 이러한 절연유 채취장치는 실린더(10)의 주입구(11)가 항상 개방된 상태로 사용되므로, 시료 채취 전이나 후에 이 주입구(11)를 통해 외부의 공기, 기포, 다른 가스등의 불순물이 유입되고, 절연유에 포함된 휘발성 가스성분 등이 누출될 수 있기 때문에, 정확한 가스분석을 어렵게 하는 문제점이 있다.By the way, the conventional insulating oil collection method is to collect the insulating oil using the cylinder 10 made of transparent glass, as shown in FIG. Therefore, since the inlet 11 of the cylinder 10 is always used in an open state, impurities such as external air, bubbles, and other gases are introduced through the inlet 11 before or after sampling. Since volatile gas components and the like contained in the insulating oil may leak, there is a problem of making accurate gas analysis difficult.

또한, 상기 절연유 채취장치는 채취되는 절연유의 상태나 채취량 등을 용이하게 확인할 수 있도록 투명의 유리로 제작되기 때문에, 사용 중 외부의 물체 등에 충돌되면 쉽게 파손되는 문제점이 있다. 또한, 상기 절연유 채취장치는 이를 안정적으로 세워놓기가 곤란하여 채취한 절연유를 신속하고 안전하게 분석하기 어렵다는 문제점과, 실린더(10) 내부로 기포 등의 불순물이 유입될 경우 이를 거꾸로 세워서 피스톤을 밀어 이를 제거하여야 하는데, 실린더(10)를 세워서 지지하기가 어려워서 불순물을 제거하기에도 적합하지 못한 구조로 이루어졌다는 문제점이 있다. In addition, since the insulating oil collecting device is made of transparent glass so as to easily check the state of the insulating oil to be collected or the amount collected, there is a problem that is easily broken when collided with an external object or the like during use. In addition, the insulating oil collecting device has a problem that it is difficult to put it stably, so that it is difficult to analyze the collected insulating oil quickly and safely, and when impurities such as bubbles enter the cylinder 10, it is necessary to push the piston upside down to remove it. However, there is a problem in that the cylinder 10 is difficult to stand up and is not suitable for removing impurities.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 절연유 시료 채취전이나 후에 외부의 공기나 기포 등의 불순물 유입을 방지하고 절연유에 포함된 휘발성 가스성분의 누출을 억제하여 정확한 가스분석이 가능하도록 하며, 실린더를 안전하게 사용할 수 있음과 더불어 채취된 시료를 안정적이고 신속하게 분석할 수 있도록 된 가스분석용 절연유 채취장치를 제공함에 있다. The present invention is to solve the above problems, an object of the present invention to prevent the inflow of impurities such as air or air bubbles before and after sampling the insulating oil and to prevent the leakage of volatile gas components contained in the insulating oil for accurate gas analysis In addition, the present invention provides an insulating oil collecting device for gas analysis, which enables to use the cylinder safely and to analyze the collected sample stably and quickly.
