Ee, za ku iya - kuma ya kamata - haɓaka janareta! Gwajin juriya na insulation (wanda aka fi sani da "Gwajin Megger") ba zai yiwu ba kawai amma yana da mahimmanci don kiyaye mafi kyau duka. rufin janareta mutunci. Wannan hanyar bincike mara lahani yana taimakawa gano shigar danshi, gurɓatawa, ko tsufa a cikin iskar iska, yana hana gazawar bala'i da faɗuwar lokaci. Ga masu samar da dizal da ke aiki a cikin mahalli masu buƙata, gwajin Megger na yau da kullun yana wakiltar ginshiƙin aikin kulawa na ƙwararru.

Tsaro Farko! Koyaushe kashe wutar lantarki ta janareta, keɓe shi daga duk hanyoyin wutar lantarki, kuma bi hanyoyin kullewa da suka dace. Tabbatar da cikakken fitar da iska zuwa ƙasa kafin da bayan gwaji.

Test Kayan aiki:

• Gwajin juriya na insulation (Megger) tare da ƙimar ƙarfin lantarki mai dacewa

• Kayan kariya na sirri (safofin hannu masu keɓance, gilashin aminci)

• Na'urar auna zafi da zafi

Tafsirin Karatun Megger

undersƘimar juriya na tanding yana da mahimmanci don ingantaccen kimanta yanayin rufin janareta:

Sharuɗɗan karɓa:

• Mafi ƙanƙantar ƙimar ƙima a kowane ma'auni na IEEE: (Ƙaramar Ƙarfafawa + 1000) / 1000 MΩ

• Ƙimar da ke ƙasa 0.1 MΩ suna nuna mummunar tabarbarewa da ke buƙatar kulawa cikin gaggawa

• Binciken kwatancen akan karatun baya da ƙayyadaddun masana'anta

Babban Ma'aunin Bincike:

• Fihirisar Polarization (karanta minti 10 / karatun minti 1)

• Dielectric Absorption Ratio (karantawa dakika 30/karanta 60 dakika)

• Zazzabi-daidaita yanayin bincike akan lokaci

Matsalolin rufewa na yau da kullun da ake iya ganowa ta hanyar fassarar da ta dace sun haɗa da ɗaukar danshi, gurɓataccen ƙurar carbon, shigar mai, da kuma tsufa. Daidaitaccen yanayin ƙasa a cikin karatu, ko da lokacin da ƙima ta kasance sama da mafi ƙanƙanta, yawanci yana nuna ci gaba rufin janareta lalatawa da ke buƙatar shiga tsakani.

• Gwajin kwata-kwata don matsananciyar mahalli (mai zafi, ƙura, gurɓatawa)

• Gwaje-gwajen riga-kafi don sababbin shigarwa

Gwajin-Tsarin Yanayi:

• Bayan tsawaita lokacin rufewa (> watanni 3)

• Bayan aikin gyara ko jujjuyawa

• Bayan bayyanar da yanayi mara kyau ( ambaliya, zafi fiye da kima)

• Lokacin da al'amurran da suka shafi aiki suna ba da shawarar matsalolin rufewa
