Umhlaba Avikelayo: ukuphepha eletropriborov

phansi Avikelayo kubhekwa ngokukhethekile uxhumano kagesi kwesizathu ngeke uphile metal izingxenye, okuyinto, ngenxa yokuvalwa izindlu kudivayisi ingavuthi bukhoma. Lokhu kwenzeka ngesikhathi okungahleliwe uxhumano kagesi ngeke uphile metallic izingxenye zalesi sihlahla amandla nezinto conductive, voltage kungaphinde kwenzeke, isibonelo, umbani.

Nge umhlaba zokuzivikela aqede ingozi yokuthi umuntu abanjwe ugesi lapho ngokuthinta izingxenye bukhoma umzimba noma imishini metal okuyinto, ngenxa earthing uvele akukhuthalele.

Kumele kube esihlukile earthing ukusebenza zokuzivikela, okuyinto yakhelwe operation kahle ukufaka kagesi, kanye lisemhlabathini ukuze awuvikele umbani. Ngu zokusebenza zingase zihlanganise isisekelo imisinga hlangothi generator emazombezombe we transformer amandla namanye amadivayisi.

Ukuze isisekelo zedivayisi ofuna ukusebenzisa amathuluzi ezingokwemvelo nasezintweni zokwakha: metal futhi amapayipi amanzi ukuthi akudingeki anti-ukugqwala enamathela, ngaphandle amapayipi amagesi alufakwa noma oluvuthayo noma uketshezi. Ifanele isisekelo phambili ikhebula sheathing, ama-valve futhi izakhi zensimbi kwagcizelela izakhiwo eziphakeme zikakhonkolo noma izakhiwo. Vele uqaphele ukuthi lokhu emhlabeni kumele abe maqondana nomhlaba. Futhi metal efanelekayo dowels noma bezinhlamvu. Kodwa angenalutho aluminium babashayeli kanye ikhebula sheathing asivunyelwe ukusebenzisa lezi zincwadi.

In the ukungabikho zemvelo emhlabeni electrode noma uma une ukumelana ingasetshenziswa kukhona yokufakelwa, ngawo ukudala isisekelo zokuzivikela. Basuke ezenziwe ngensimbi ekhoneni izingxenye 5h5h0,5 cm ubude 2-3 amamitha, usayizi ofanayo ka ngamapayipi ensimbi ngenhloso ububanzi ka 5 cm steel izingxenye isiyingi (ubude 5 m, ububanzi 12.0 - 14.0 mm). izingxenye asetshenzisiwe (electrode) kumele egxilile phansi buqamama komunye nomunye we 3-5 amamitha, kumele zonke izakhi exhunywe phakathi isiqeshana steel, esigabeni ngesiphambano 40x4 mm.

Strip yokuxhuma ibekwe emseleni a ka 0.70 metres ukujula, elifanayo ukusuka amaqabunga emikhawulweni engenhla electrode. Zonke izici axhunyiwe ngu Welding. Isibalo electrode ibalwa, esekelwe inhlabathi resistivity, usayizi electrode, ukujula okokuqandisa nezinye izinto.

Avikelayo isisekelo voltage kagesi izinkulungwane B kungenzeka ihlelwe usebenzisa metal izakhiwo ezingaphandle kwesakhiwo (ebukhoneni ukuxhumana okuthembekile izakhi wesifunda), wirings amashubhu steel, i-aluminiyamu ikhebula emigodleni, metallic amapayipi (ngaphandle amasistimu wokushisa, nendle iphayiphi). metal emathileyi, amabhokisi, ezivalekile bese busbars zero wire izifunda (umhlaba zokuzivikela futhi singathathi hlangothi) liyasetshenziswa.

Njengoba babashayeli zokuzivikela zero asivunyelwe ukusebenzisa metal neziqhumane mncane kuholele izintambo futhi izintambo. Air AC luzophela ngokusebenzisa umqhubi hlangothi, ezibekwe at ezisekelweni efanayo babashayeli isigaba.

Nokho, Vanishing akusho ngaso sonke isikhathi ukuqinisekisa ukuphepha ezidingekile nabantu abaxhumana ukufakwa kagesi. Kwezinye izimo, ezindaweni babe sengozini enkulu yokufa nokunyamalala, kanye kabusha ukusetshenziswa earthing ovikelayo noma ukuphepha ukuvala shaqa isetshenziswa. izintambo Avikelayo kokungathathi hlangothi asivunyelwe ukusebenzisa uhlelo nokunyamalala of zikagesi, zidla nezinye imigqa, njengoba kungacinywa sesondlo.

Ukuze amadivayisi zokuzivikela zihlanganisa wesifunda amadlambi, isabela zamanje ukuvuza. Ukusetshenziswa kwalezi amadivayisi amafulethi angathuthukisa ukuphepha kagesi.
