て油入電器１内の油をクーラ５に送って冷却している。[Background of the Invention Technique 1fj] In general, in an oil-filled electrical appliance such as an oil-immersed transformer, in addition to the oil-filled electrical appliance 1 shown in FIG. 5. The oil flow indicator 6, oil pump 8, and lower valve 10 are connected to the lower oil pipe 4 and the intermediate oil pipe 7.
, are arranged in sequence with lower oil pipes 9 interposed therebetween, and heat loss caused by the operation of the oil-filled appliance 1 is cooled by sending the oil in the oil-filled appliance 1 to the cooler 5 by operating the oil pump 8.

＝Ｊけられている。The oil pump 8 is installed at a location near the floor below the oil-powered appliance 1 in order to perform daily inspections such as operation noise, periodic inspections such as hair ring replacement, and repairs. In addition, an oil flow indicator 6 that displays the oil flow status of the oil pump 8 is also installed at the bottom of the oil-filled electrical appliance 1 in order to monitor the indicator.
=J is kicked out.
このように、クーラ５の下方に油流指示器６−油ポンプ
８−下部弁１０と順次直列に配置している油入電器１の
冷却装置においては、油流指示器６の正常な動作を得る
ために油流の乱れのない直管部を油流指示器６の前後に
必要とする。In this way, the oil flow indicator 6, oil pump 8, and lower valve 10 are arranged in series below the cooler 5 in the cooling system for the oil-powered appliance 1, in order to ensure the normal operation of the oil flow indicator 6. In order to obtain this, a straight pipe portion without turbulent oil flow is required before and after the oil flow indicator 6.

、また油流指示器６の下流側−Ｃは、油ポンプ８の運転
中羽根車の回転によって生ずる乱流があって、これらが
油流指示器６内の流れを非常に複雑にする。That is, at the upstream side of the oil flow indicator 6, there is turbulence that occurs when the oil flows from the oil box of the cooler 5 to the oil pipe, and at the downstream side -C of the oil flow indicator 6, there is a turbulent flow that occurs when the oil flows from the oil box of the cooler 5 to the oil pipe. There are turbulences caused by the rotation of the car and these make the flow in the oil flow indicator 6 very complicated.

吸込口付近の渦流による局部的な流れが油流指示器６を
正常な流れとして指示させるなどという問題がある。On the other hand, in order to eliminate the negative effects caused by such a phenomenon, it is possible to lengthen the piping between the lower part of the cooler 5 and the suction port of the oil pump 8. It is almost impossible to realize this because of various problems, such as the need to make the upper oil pipe 4 a strangely shaped oil pipe that tends to trap air, and to make the servitor 2 of the oil-filled electric appliance 1 higher. Therefore, it is geometrically extremely difficult to attach the oil flow indicator 6 to an oil pipe with few straight pipes, catch the oil flow condition, and transmit it to the outside, so a complicated transmission mechanism is required. . In addition, if the upper and lower valves at the inlet and outlet of the oil-powered electric appliance 1 are operated incorrectly and the oil pump 8 is operated with the valves closed, the rotation of the impeller may cause a localized flow due to a vortex near the pump suction port to cause an oil flow indicator. There is a problem that 6 is indicated as a normal flow.
［発明の目的］
本発明の目的とするところは、簡単な構成でしかも油流

An object of the present invention is to provide a cooling device for oil-filled electrical appliances that can be monitored.

［発明の実施例］ 本発明の一実施例の構成を第２図にボッ。[Embodiments of the invention] The configuration of one embodiment of the present invention is schematically shown in FIG.
すなわち、第２図に示すように、第１図に示した従来装

、油ポンプ８は１図示のようにクーラ５の下部出口と油
入電器１の下部人口弁との間に設けられることになる。That is, as shown in FIG. 2, the oil flow indicator 6, which was provided below the cooler 5 and close to the oil pump 8 in the conventional device shown in FIG. The oil flow indicator 6 is attached to the oil pipe 4 that connects the upper outlet valve of the electric appliance 1 and the upper inlet of the cooler 5. In this case, the oil pump 8 will be provided between the lower outlet of the cooler 5 and the lower artificial valve of the oil-powered electric appliance 1, as shown in FIG.
なお、この実施例では、油流指示器６は、図示の洋に上
向きに取付１ノでいる。In this embodiment, the oil flow indicator 6 is mounted facing upward in the ocean shown in the figure.
このように構成すると、油流指示器６は油ポンプ８から

流指示器６ににり容易に異常どして検知することができ
る。With this configuration, the oil flow indicator 6 is attached to the oil pipe 4 far away from the oil pump 8.
It is not affected by vortices or local currents caused by the operation of the Therefore, the oil flow indicator 6 that simply catches the average oil flow (with almost no turbulence) flowing in the pipe is sufficient, and the structure of the oil flow indicator 6 can be made simple, making it inexpensive and of high quality. Can be used. In addition, since it operates with less turbulent oil flow, not only the performance is greatly improved, but also the upper and lower valves of electrical appliances.
Even if the oil pump 8 is operated by accidentally closing the oil flow indicator 6, the oil flow indicator 6 can be used to easily detect an abnormality.

た場合は油流の変動も少なく指示値も正確であるので、
さらに日常点検の必要性はなくなり、日常点検の点検項
目を減らづことができるなどのメリットも生づ゛る。The movement of the oil flow indicator 6 is essentially to check the rotational direction of the oil pump 8, and to check for wiring connection errors when the oil pump 8 is installed or reinstalled due to bearing or gasket replacement. Therefore, once the oil pump 8 is in operation, there is no need to monitor it in particular. This is because the insulating oil of the oil-filled electrical appliance 1 is clean with controlled moisture and gas amounts, and there is almost no foreign matter mixed in, so fluctuations in the oil flow are completely unthinkable. Further, even if the oil flow fluctuates, the contacts of the oil flow indicator 6 can operate to notify the abnormality. Therefore, there is little need to install the oil flow indicator 6 below the oil-filled electrical appliance 1 for daily inspection, and in particular, install the oil flow indicator 6 at a location where the oil flow is extremely stable as described above. If installed, there will be less fluctuation in oil flow and the indicated value will be accurate.
Furthermore, the need for daily inspections is eliminated, and the number of items to be inspected in daily inspections can be reduced.
なお、本発明は上述し且つ図面に示す実施例にのみ限定
されることなく、その要旨を変更しない範囲内で種々変
形して実施することができる。It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without changing the gist thereof.

合にも点検作業等は一層簡単になる。For example, as shown in FIG. 3, the oil flow indicator 6 can be attached to the side or bottom surface of the upper oil pipe 4 so that the indicated value can be seen from below the oil-filled electrical appliance 1. In this case, inspection work, etc., becomes easier even when checking the indicated value of the oil flow indicator.
