に機器の絶縁能力を低下させる。DETAILED DESCRIPTION OF THE INVENTION Background of the Invention Many types of electrical equipment, including transformers, cables, and capacitors, contain insulating oil. In some cases, these devices lose insulating oil C when a leak occurs. Loss of insulating oil draws moisture into the electrical equipment, reducing the equipment's insulation ability to the point that the electrical equipment fails.

は意識を失うに至る。When the insulating oil is mineral oil or other oil with a color and is fairly non-volatile, it is easy to detect the insulating oil leak by finding the insulating oil leaking outside the electrical appliance. . However, since the insulating oil is colorless and volatile, it is very difficult to detect the leaked oil, and since it does not remain outside the electrical machine for a long time, it is difficult to detect the leaking point. is extremely difficult. An example of such an insulating oil is perchlorethylene, which is widely used in transformers. This insulating oil is colorless and quite volatile, which makes it difficult to detect where the insulating oil has leaked, and since insulating oil is heavier than air and almost odorless at low temperatures, perchlor When ethylene leaks out, it displaces the air in the room, causing the person inside to become dizzy and eventually lose consciousness.

は検出に必要な手段は紫外光だけであるからである。SUMMARY OF THE INVENTION We have discovered that if certain fluorescent dyes are added to halogenated insulating oils, leakage of the insulating oils can be easily detected under ultraviolet light that causes the dyes to fluoresce. Ta. The dye does not interfere with the electrical or physical properties of the insulating oil within the equipment in which it is used. This dye can be easily added to these types of insulating oils at a relatively low cost. The dye was found to be stable in dielectric oil, non-mutagenic, and non-carcinogenic. Another advantage of using dyes is that leaks of insulating oil can be easily detected even in the wild. The reason for this is that the only means necessary for detection is ultraviolet light.

ある。This insulating oil includes transformers, cables, and condensers that use insulating oil. Although it can be used in any electrical machine, it is particularly useful in transformers. This is because this type of transformer uses a large amount of perchlorethylene as insulating oil, and the leakage of insulating oil is more likely than in other equipment.
