である。DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a method for inspecting and repairing a disconnector/grounding device used as one of power plant or substation equipment.
（従来の技術）
一般に、発電所あるいは変電所設備の１つであるＩＪＪ

時には、不完全投入、不完全接触又は開路動作不能とな
る場合がある。従って、良好な開閉動作を維持するため
に３年に１回の周期で定期的に断路器あるいは接地装置
の各部を点検、清掃し、接触子の接触面や機構部の摺動
軸受部に潤滑油を塗布している。(Prior art) In general, IJJ, which is one of power plant or substation equipment,
In order to maintain good operation of the electrode section and mechanism section of the road device or grounding device, lubricant is applied to the contact surface of the contact and the sliding bearing section of the mechanism section as a measure to reduce sliding resistance due to friction. However, since the electrical disconnector or grounding device (headquarters and machine 41) are installed outdoors, dust may adhere to and solidify on the lubricating oil coating area, or it may be exposed to wind and rain. The lubricating oil may leak or evaporate, increasing friction or sliding resistance, and as a result, when opening and closing a disconnector or grounding device, incomplete closing, incomplete contact, or inability to open the circuit may occur.Therefore, In order to maintain good opening/closing operation, periodically inspect and clean each part of the disconnector or grounding device once every three years, and apply lubricating oil to the contact surfaces of the contacts and the sliding bearings of the mechanical parts. It is being applied.
この定期点検は発電所あるいは変電所の停電を伴うとと
もに、人的経費も必要なばかりか、定期的に行う点検は
断路器あるいは接地装置の開閉動作を良好に維持する目
的で行なうので、開閉動作が良好なものまで点検するこ
とになり不経済である。This periodic inspection not only involves a power outage at the power plant or substation and requires human resources, but also because periodic inspections are performed for the purpose of maintaining good opening/closing operation of the disconnector or grounding device. This is uneconomical as it means inspecting even those that are in good condition.
一方、新路器あるいは接地装置が悪環境下に設置されて
いる場合は、３年周期の窓明点検以内で前記摺動抵抗が
増大し点検前に断路器あるいは接地装置の前記開閉動作
が不良となる場合や、電力需要の関係で停電がとれず、
３年周期の点検が繰延べされる場合もあって、そのため
開閉動作不良となる問題がある。On the other hand, if a new circuit switch or grounding device is installed in a bad environment, the sliding resistance increases within the 3-year window inspection, and the opening/closing operation of the disconnector or grounding device is found to be defective before the inspection. In some cases, power outages cannot be achieved due to electricity demand,
In some cases, the three-year inspection is postponed, resulting in problems with opening and closing operations.

を解決しようとしている。(Problems to be Solved by the Invention) The present invention solves the problems that exist in the above-mentioned conventional method of periodically inspecting and cleaning each part of a disconnector or grounding device and applying lubricating oil, that is, a power plant or a substation. This can lead to power outages and increase human costs, and it is uneconomical to have to inspect things that don't need to be inspected.Furthermore, disconnectors or grounding devices may malfunction before inspection, and power outages may occur due to power demand. We are trying to solve the problem where inspections are postponed due to failure.
