Description
この考案は、高電圧受配電設備が経年劣化等により、コロナ放電現象を発生した場合、高電圧受配電設備内の酸素を分解してオゾンガスが発生する。このガスを検出することによりコロナ放電現象を捕促し高圧受配電機器が絶縁破壊に至たるまえに、当該機器を更新し、破損事故・突発停電を未然に防止するものである。In this device, when the corona discharge phenomenon occurs due to deterioration of the high voltage power distribution facility due to aging, etc., ozone gas is generated by decomposing oxygen in the high voltage power distribution facility. By detecting this gas, the corona discharge phenomenon is captured and the device is updated before the high-voltage power receiving / distribution device breaks down to prevent damage and sudden power failure.
高圧受配電設備は、月例・年次の定期点検及び、数年毎の精密点検が法律で義務付けされており、また、臨時に点検して異常を発見した場合は、所定の専用計測機器で検査・診断を行い異常状態を除去するが、復旧作業にかかる時間・経済的損失は多大となる。High-voltage power distribution facilities are required by law to have regular monthly and yearly inspections and precise inspections every few years. In addition, if abnormalities are found through temporary inspections, inspections are performed using specified dedicated measuring equipment.・ Diagnosis is performed to remove abnormal conditions, but the time and economic loss for restoration work will be significant.
オゾンガス・センサ−の文献はあるが、高圧受配電設備に常備して連続監視・警報を発生するものはない。
また、コロナ現象リーク音については、次の内容が周知されている。
高電圧受配電設備の、絶縁耐力試験を実施したとき
１）「ジジジジ・・・・」と連続吃音が発生する。
２）周囲が暗いと青白い光を認めることが出来る。
３）湿度が高い場合は、１）項のような独特のリーク音が認められる。
４）高電圧機器の口出し線が、接近している個所や、極端に折り曲げている箇所からも、この現象は見られる。
５）充電部分が鋭角で、絶縁物に接しているケースでは、コロナリークがあった跡は、表面が白色化して、内部は徐々にカーボン化する。
これらの現象は公知のものである。また高電圧受配電設備が、その機能を低下させ、オゾンガスを発生したときは、人間の五感によって、その機能低下を確認されている。
現在は連続してオゾンガスを常時監視し、異常発生時、これを知らせる検出装置はない。Although there is a literature on ozone gas sensors, there is no one that always keeps high voltage power distribution facilities and generates continuous monitoring / alarms.
Moreover, the following content is known about the corona phenomenon leak sound.
When a dielectric strength test is performed on a high-voltage power distribution facility 1) A continuous noise is generated as “jijijiji”.
2) When the surroundings are dark, a pale light can be recognized.
3) When the humidity is high, a unique leak sound as in 1) is observed.
4) This phenomenon can also be seen from the location where the lead wire of the high-voltage equipment is close or extremely bent.
5) In the case where the charged part has an acute angle and is in contact with the insulator, the trace of corona leak is whitened on the surface and gradually carbonized inside.
These phenomena are known. Moreover, when the high-voltage power distribution facility deteriorates its function and generates ozone gas, it is confirmed by the human senses that the function is deteriorated.
Currently, there is no detection device that continuously monitors ozone gas continuously and notifies when an abnormality occurs.
本考案に係わるコロナ放電検出装置は、函体型及び開放型高圧受配電設備内で、オゾンガス発生対象機器（高電圧交流負荷開閉器等）
を内蔵した装置・機器に接近して装備されるもので、次の条件を充たす場所に設備する。
１） オゾンセンサーは０〜２５０ ｐｐｂで制禦
２） コロナリーク音を感知できる離隔距離。
３） 湿度５０％以下。
４） 高電圧機器の口出し線からは１００ｍｍ（離隔距離）
コロナ放電によって、分解された大気中の酸素から発生するオゾン・ガス臭（生臭い・魚の腐った様な臭気）を検出して、現象を確認する。その信号を監視盤へ送り機器破損・突発停電を未然に防止する。The corona discharge detection device according to the present invention is a device for generating ozone gas (such as a high-voltage AC load switch) in a box-type or open-type high-voltage power distribution facility.
It will be installed in close proximity to equipment / equipment with built-in and installed in a place that satisfies the following conditions.
1) Ozone sensor controlled at 0-250 ppb 2) Separation distance that can detect coronal leak sound.
3) Humidity 50% or less.
4) 100mm from the lead wire of high-voltage equipment (separation distance)
The phenomenon is confirmed by detecting ozone and gas odors (raw odors and rotten odors of fish) generated from oxygen in the atmosphere that has been decomposed by corona discharge. This signal is sent to the monitoring panel to prevent equipment damage and sudden power outages.
１） 常時、予め設定した濃度の範囲内で検出する。（同じ水準で）
２） 人間の臭覚感知は、オゾン濃度 ０〜５０ ｐｐｂである。
３） オゾンセンサーは ０〜２５０ ｐｐｂで感知する。
この２）３）の濃度レベル幅を監視して、前出対象機器が破損、突発停電を起こす要因に至る前に、コロナ放電から発生するオゾン臭を感知し、このオゾン臭発生の要因を、除去する装置を提供する。1) Always detect within a preset concentration range. (At the same level)
2) Human olfactory perception is ozone concentration 0-50 ppb.
3) The ozone sensor senses from 0 to 250 ppb.
2) The concentration level range in 3) is monitored, and the ozone odor generated from corona discharge is detected before the above-mentioned target device is damaged and causes a sudden power failure. An apparatus for removing is provided.

２）オゾンガス濃度を監視しで設備機器の状況が把握でき、対策が事前に出来る。
３）機器破損・突発停電が防止できる。
４）原因不明の当該機器故障の要因を、早期に発見・除去できる。1) The state of damage due to corona discharge of high voltage power distribution equipment can be continuously monitored for 24 hours.
2) By monitoring the ozone gas concentration, the status of the equipment can be grasped, and measures can be taken in advance.
3) Equipment damage and sudden power failure can be prevented.
4) The cause of the device failure of unknown cause can be detected and removed at an early stage.
臭覚の敏感でない電気管理技術者を対象に、携帯用オゾン感知器を、絶縁機能を持つ伸縮棒の先端に装備し、当該電気機器を点検することも可能である。
また、本考案を実施するための、形態について説明する。高電圧受配電設備の、内部に装置している電気機器の、絶縁状態が劣化して、機能維持が困難になると、センサー周辺の酸素を分解してオゾンガスが発生する。この発生したオゾンガスを捕捉して、コロナ放電現象を検出し、電気機器の絶縁破壊に至る前に、当該電気機器を特定して更新し、機器破損事故を未然に防止する。
このコロナ放電検出装置により、外部へ警報信号を送り、オゾンガス臭を濃度値により機器の損傷程度を特定して処置をする。For electrical management engineers who are not sensitive to smell, it is also possible to equip a portable ozone sensor at the tip of a telescopic rod having an insulating function and inspect the electrical equipment.
Moreover, the form for implementing this invention is demonstrated. If the insulation state of the electrical equipment installed in the high-voltage power distribution facility deteriorates and it becomes difficult to maintain its function, the oxygen around the sensor is decomposed and ozone gas is generated. The generated ozone gas is captured to detect a corona discharge phenomenon, and the electrical equipment is specified and updated before the electrical equipment is broken down to prevent an equipment damage accident.
With this corona discharge detection device, an alarm signal is sent to the outside, and the ozone gas odor is treated by specifying the degree of damage to the device by the concentration value.
