Field of the Invention The present invention relates to an improvement in a transformer diagnostic device for diagnosing a deterioration or abnormality of a transformer, and more particularly to an improvement in a diagnostic device using an optical fiber as a detecting portion.

Description of the Related Art In oil-filled equipment such as transformers, insulating oil deteriorates for various reasons during long-term operation, for example, penetration of rainwater due to deterioration of a gasket that secures airtightness and oxidation. In addition, the insulating paper or the like may be decomposed by operating for a long time at a high temperature, and the constituent components of the paper such as cellulose may be eluted in the oil, and CO (carbon monoxide), CO2 (carbon dioxide), etc. may be dissolved.

溶解する。On the other hand, when an internal abnormality occurs and local heating, corona discharge, arc discharge or the like occurs, an insulating material such as insulating oil or insulating paper is decomposed to generate a flammable gas. This flammable gas is a compound consisting of carbon and hydrogen such as H2 (hydrogen), CH4 (methane), C2H2 (acetylene). Most of this flammable gas also dissolves in the insulating oil.

ている。Therefore, conventionally, the characteristics of insulating oil are investigated, and at the same time, the components and gas components in the insulating oil are analyzed to detect deterioration or abnormality of the oil-filled equipment at an early stage, which is useful for preventing accidents. Came. As a method of detecting the components and gas components in this insulating oil, a person has conventionally taken oil from an oil-filled device, for example, an oil discharge valve of a transformer, etc., and analyzed in a laboratory with an analyzer such as gas chromatography. Off-line processing is mainly performed. In addition, recently, for example, JP-A-5-8
As described in Japanese Laid-Open Patent Publication No. 1042, an automatic analyzer that conducts oil extraction into a diagnostic device by connecting a pipe to an oil discharge valve of a transformer and automatically performs from gas extraction to analysis has also been commercialized. .

属され運転が行なわれている。FIG. 6 is a diagram showing a system of a diagnostic device of this type which is generally adopted in the past. In the figure, reference numeral 1 is a transformer, inside of which a winding and an iron core (not shown), which are main devices, are incorporated, and an insulating oil 2 is filled. A hot-line oil purifier 8 and a load tap changer 10 are attached to the transformer 1 for operation.

And the like, and inputs these detected values to the diagnostic device 20,
Performs calculations and judgments. At the same time, the oil discharge valve 11 and the diagnostic device 20 are connected by a pipe 27 to guide the oil into the diagnostic device 20. The diagnostic device 20 has a part for extracting gas from oil (not shown) and a part for analyzing the extracted gas component to specify the concentration, and is equipped with a device for performing advanced online processing that constitutes a kind of experimental device. ing.

のが普通である。As described above, in the past, in order to diagnose the deterioration and abnormality of the transformer, a laboratory offline processing,
It is usual to analyze the components in insulating oil and gas by online processing that incorporates a sophisticated gas analyzer.

そのものも極めて効率の悪い作業である。However, in the case of the off-line processing, as described above, a person collects oil or gas and performs the analytical processing in a laboratory with an analyzer such as gas chromatography, so that it is inevitably lacking in immediacy and convenience. I have a hate. In addition, when it is desired to grasp the tendency of changes in the gas amount in a relatively short period of time, it is necessary to collect oil each time, and in the case of an unmanned substation that is far from the power demand area, the dispatch of personnel is also necessary. This is extremely inefficient work.

きくなる嫌いがある。On the other hand, in the case of on-line processing in which a sophisticated gas analyzer is incorporated, the experimental apparatus is automatically incorporated and the system is not only complicated, but also considerably expensive. . When the main transformer is a high-capacity transformer of ultra-high voltage class or higher, the ratio of the diagnostic device to the total price is not so large, but in the case of a distribution class medium / small capacity transformer. , I hate that the proportion to the whole becomes large.

の場で直接検出診断する診断装置がある。As a device relatively free from these problems, for example, as disclosed in Japanese Patent Application Laid-Open No. 60-2012238, there is provided a diagnostic device in which an optical fiber is placed in oil or gas and directly detected and diagnosed on the spot. is there.

た。The diagnostic device for arranging the optical fiber in oil is relatively inexpensive and does not need to be sampled for each diagnosis, and the system is simple and has good immediacy and convenience. However, this device is difficult to adjust because the optical fibers are arranged so as to face each other in the oil, and when used for many years, there is a dislike of lack of reliability due to a shift of the facing surface and a facing gap.

のである。That is, in the diagnostic device thus formed, an optical fiber arranged so as to penetrate the oil in the oil sump or the gas in the gas sump is provided, and the end of this optical fiber is provided. Since the light emitting device and the light receiving device are combined, it is possible to predict and diagnose the deterioration degree of the transformer, the generated gas concentration and the presence or absence of abnormality by detecting the attenuation of the light that passes through this optical fiber. Alternatively, the light passing through the optical fiber in the gas is attenuated due to the deterioration of the oil and the change in the refractive index of the medium outside the fiber due to the surrounding gas. By detecting this, the degree of deterioration of the transformer, the concentration of generated gas and the presence or absence of abnormality can be sufficiently detected, and at this time, the optical fiber is arranged so as to penetrate into the oil in the oil sump or the gas in the gas sump. Therefore, it is not necessary to adjust the facing gap and the facing angle of the optical fiber as in the case of the conventional diagnostic apparatus using the optical fiber. Therefore, the configuration is simple and inexpensive, and the advanced adjustment is not required. Even if it is used for many years, it will be highly reliable with no change in the detected value.

ン化が可能である。As described above, the effect that the detecting section 25 of the optical fiber penetrating through the oil can detect the deterioration of the oil is that when the refractive index of the oil changes due to the deterioration of the oil around the oil deterioration detecting section 25, that portion is changed accordingly. The attenuation of the light passing through changes.
