In particular, due to the widespread use of electronic equipment, office automation equipment, and the like in the general society, it is becoming difficult to perform power outages even when inspecting electrical equipment, so tools that can be inspected without power outages are desired. [Structure] A microphone (2) for emphasizing corona discharge sound and a main body (1) containing an amplifier (3) for the same purpose, which is less susceptible to ambient noise, can withstand high voltage and are replaceable. A feature is that the search tube (6) can be attached.

[Industrial applications]

この考案は、高圧回路の絶縁不良によるコロナ放電を、音響として捕捉し、停電することなく放電箇所を探索、特定する用具である。 The present invention is a tool for capturing corona discharge due to poor insulation of a high-voltage circuit as sound and searching for and identifying the discharge location without stopping the power.

【０００２】[0002]

[Prior Art]

高圧回路の絶縁不良によるコロナ放電は、微弱な音響を伴うため聴覚により検出する方法があった。 Corona discharge due to poor insulation of the high-voltage circuit is accompanied by faint sound, so there was a method of detecting it by hearing.

[Problems to be solved by the device]

これには、次のような欠点があった。（イ）聴覚による検出は、音響が微弱なため、電気設備の発する運転音または周囲の騒音に埋もれて発見が困難であった。（ロ）検出された場合でも、高圧電気が通電されているため接近できず、放電箇所を特定するには、停電して精査確定する必要があった。本考案は、これらの欠点を除くためなされたものである。 This had the following drawbacks. (B) In the case of auditory detection, since the sound is weak, it was difficult to find it because it was buried in the driving noise generated by electrical equipment or the ambient noise. (B) Even if it was detected, it could not be approached because the high-voltage electricity was energized, and in order to identify the discharge location, it was necessary to confirm the power failure and confirm it. The present invention has been made to eliminate these drawbacks.
