Haɗa Modul ɗin Rana: Jagora Mai Aiki don Gyara Matsalolin Solder Sanyi (Tare da Taswirar Hankali)
Gabatarwar Samfur
Babu dogon gabatarwa. Taswirar hankali ta fara. Idan ya taimaka, ajiye labarin kuma sauke hoton. Hakanan zaka iya tuntuɓar mu ta hanyar WeChat don shiga rukunin tattaunawa na fasaha na PV module don samun sigar babban ƙuduri. (Kawai gaya mana wane bangare kake gudanarwa, kamar tsari, inganci, kayan aiki, ko samarwa.)
Kafin mu shiga cikin gyaran cold solder, bari mu ga yadda stringing ke aiki. Ribbon, wanda injin zane ya ja, an sanya shi daidai a saman busbar na cell. Sa'an nan kayan aikin walda ya sauko, kuma maƙallan latsawa a kan kayan aikin suna matsa ribbon don ta taɓa busbar. Cell ɗin yana motsawa ƙarƙashin akwatin haske na stringer, inda infrared ke dumama ribbon da cell. Tin a kan ribbon yana narke kuma yana haɗuwa da man azurfa a kan busbar, yana samar da gami na ƙarfe.
Abu ɗaya da za ka tuna. Ga duk wani bincike na cold solder, duba wuraren da farin (wanda ba a haɗa shi ba) ya bayyana da farko. Idan ka ga farin da ya bayyana, magance shi kafin ka yanke hukunci game da soldering ɗin kansa. Duk abin da ke ƙasa yana amfani da stringing na cell TOPCon da stringer ATW050 a matsayin misali.
Kamar yadda aka nuna, ribbon na farko, na biyu da na uku a cikin akwatin ja sun bayyana farare. Na huɗu a waje da akwatin yana da kyau.
Ma'auni na Fasaha
1. Cold solder na gaba gabaɗaya
Lokacin da duk gefen gaba ya nuna cold solder, duba waɗannan:
| Abu | Abin da za a duba |
|---|---|
| Akwatin haske | Mai da hankali kan sigogin soldering. Shin akwatin haske yana tsufa? Duba duk wani abu da ke shafar dumama gabaɗayan panel. |
| Tsayin walda | Lokacin tsayawa, akwatin haske yana ɗagawa kaɗan don guje wa walda fiye da kima a ƙarƙashin tantanin halitta. Idan tazarar tsakanin akwatin haske da dandalin walda ta yi yawa yayin walda, ingancin infrared yana raguwa kuma kuna samun walda mara kyau. |
| Lokaci da ƙarfi | Lokacin walda da ƙarfin akwatin haske sune manyan abubuwan. Bincika waɗannan da farko. |
| Matsakaicin flux | Flux mara kyau, musamman ƙarancin ƙarfi, ya kasa tsaftace oxide daga saman ribbon, kuma ingancin walda yana raguwa zuwa walda mara kyau na gaba ɗaya. |
| Kayan shigowa | Tantunan da ke da ƙarancin man azurfa suna haifar da walda mara kyau ko walda fiye da kima. Ruwancin tin mara daidaituwa akan ribbon yana nufin wuraren siraran ba za su iya haɗuwa da man ba. Flux da ya ƙare ko ya lalace ba zai cire oxides ba kuma haɗin ya gaza. |
| Kayan aiki | Shin kayan aikin yana tsakiya? Kayan aikin da ba a tsakiya ba yana nufin fil ɗin matsi ba zai iya riƙe ribbon a kan busbar ba, yana barin tazara da walda mara kyau. Hakanan bincika fil ɗin matsi da kansu. |

2. Walda mara kyau na gaba mai ribbon guda ɗaya
Tunda ribbon guda ne, kawai duba injin da ke da alaƙa da wannan ribbon.
| Abu | Abin da za a duba |
|---|---|
| Zane | Sako-sako da clamp ɗin zane, clamp ɗin da ya lalace, ko kuma mara kyau na clamp bearing. Duk wani lahani a kan injin ribbon guda ɗaya yana sa ribbon ya fita daga matsayi kuma ya lalata haɗin. |
| Ɗagawa | Abu na waje a cikin ramin jagorar ɗagawa, ko kuma ribbon ɗin yana goge a cikin ramin. |
| Kayan aiki | Kayan aiki na yau da kullun? Kayan aiki ya lalace? Matsi na pin ba daidai ba? |
| Bututun haske | Don sanyi mai ƙarfi a wuri mai tsayi, duba bututun haske a wannan wuri don tsufa ko ƙarfin da bai dace ba. |
| Mai yanka | Bayan yanka, ribbon ɗin yana da lankwasa ko ƙura? Dukansu suna sa ribbon ɗin ya goge a kan bel ko wasu sassa kuma ya lalata haɗin. |

3. Sanyi mai ƙarfi na gaban kai
| Abu | Abin da za a duba |
|---|---|
| Akwatin haske | Shin farantin inuwa ya lalace ko yana toshe bututun haske? Matsayin farantin inuwa mara kyau yana sa ribbon ɗin ya narke tin kafin ya shiga akwatin haske, wannan shine narkewar tin da wuri, kuma kuna samun sanyi mai ƙarfi na kai. Duba ikon jiran aiki da lokacin siyar da bututun haske. |
| Kayan aiki | Shin kayan aikin yana da baka ko ya lalace? Kayan aiki mai baka ba zai iya matse ribbon ba, don haka cold solder yana bayyana. Shin duk maƙallan matse suna riƙe kan solder? Shin kayan aikin yana zamewa? |
| Ribbon | Ribbon da ya lalace ko ya miƙe fiye da kima yana lanƙwasa kuma ba zai iya daidaita da busbar ba, yana haifar da cold solder. Hakanan duba ƙarshen ribbon da ya ɗaga, wanda ba zai iya taɓa busbar ba. |
| Sauran | Shin an bushe danshi bayan yanke cell? |
4. Cold solder na kai da wutsiya
| Abu | Abin da za a duba |
|---|---|
| Zane | Ƙarshen ribbon da ya ɗaga ko ribbon da ya miƙe fiye da kima. |
| Kayan aiki | Maƙallan matse ya faɗi, ya lalace, ko ya makale. Cold solder na tabo yawanci yana fitowa daga matsalar maƙallan matse. Idan babu maƙallan, ribbon ba zai iya isa busbar ba. |
