Sireletsang lefatše: polokeho eletropriborov

fatše sireletsang e nkoa e khethehileng entsoeng mabapi motlakase ho lebaka la se phela likarolo tsa tšepe, tseo, ka lebaka la ho koalo tsa sesebediswa matlo a ka ba tla phela. Hlahellang ka mabapi tšohanyetso motlakase ba sa phela likarolo metallic tsa semela matla le thepa ea motheo e conductive, ho gagamalo ka boela la hlaha, ho etsa mohlala, lehalima.

Le lefatše le sireletsang felisa kotsi ea makala motlakase ha ho ama likarolo tse u phele tsa 'mele tsa tšepe kapa thepa eo, ka lebaka la earthing hlaha kentse letsoho.

E lokela ho ba hlaheletseng ho tswa ho sebetsa earthing sireletsang, e etselitsoeng ho tshebetso e nepahetseng ka ditlhomo motlakase, hammoho le ho tloha fatše ho sireletsa e tsoa ho e lehalima. Ke sebetsa ka kenyelletsa hexagon le maqhubu a sa nke lehlakore ha jenereithara matsoelintsoeke ea matla transformer le lisebelisoa tse ling.

Bakeng sa hexagon ea sesebelisoa sa u batla ho sebelisa lithulusi tsa tlhaho le thepa: tšepe le liphaephe metsi se nang-ba khahlanong le ts'enyeho barbotage, ho sa kenyeletswe lipeipi le likhase tse phatlohang, kapa chang kapa sephalli. A loketse bakeng sa hexagon etella pele kabel sheathing, di-valve le likarolo tsa tšepe tsa matlafatsoa meaho e hahiloeng ka konkreite kapa mehaho e. Feela ho hlokomela hore lefatše lena e tla ba le mabapi le lefatše. Hape dowels loketse tšepe kapa kenapa. Empa a se nang letho aluminium conductors le kabel sheathing e hanetsoeng ho sebelisa tsa boitsebiso boo.

A ho ba sieo tsa li-electrode tsa tlhaho lefatše kapa haeba ba na le ho hanyetsa phahameng ka sebelisoa ke maiketsetso, eo ka eona bopa hexagon sireletsang. Ba li etsoa la tšepe sekhutlo likarolo 5h5h0,5 cm, bolelele ba limithara tse 2-3, boholo e tšoanang ea lipeipi tšepe ka bophara tsa 5 cm, tšepe likarolo tse chitja (bolelele 5 limithara, bophara 12,0 - 14,0 limilimithara). likarolo Used (li-electrode) e lokela ho qoelisoa mobung le hōle le e mong le tse ling tsa limithara tse 3-5, likarolo tsohle e lokela ho amana pakeng rolo tšepe, le karolo sefapano sa limilimithara 40x4.

The hlobolisa tlohang e kenngoa ka foro ho ka botebo ba limithara tse 0,70, sebaka se tšoanang ho tloha holimo ke ea lipheletsong ka holimo ea li-electrode ho. likarolo tsohle tse amanang ka ho tjheseletsa. palo ea li-electrode e balwa, e thehiloeng resistivity mobu, eleketrode boholo, leqhoa botebo le lintho tse ling.

Sireletsang hexagon motlakase gagamalo ho likete B ka hlophisitse sebelisa tšepe dibopeho tsa mohaho (ka ho ba teng ha mabapi le e ka tšeptjoang ea likarolo oa potoloho), wirings methapo tšepe, aluminium sheaths kabel, liphaephe metallic (ntle le bakeng sa tsamaiso ea bohareng futhumatsang, le lipeipi likhoerekhoere). tšepe diterei la, mabokose, masakeng le busbars lipotoloho lefela terata (sireletsang lefatše le ho se nke lehlakore) le boetse le sebelisoa.

Ka conductors sireletsang lefela e hanetsoeng ho sebelisa tšepe le likhetla tšesaane lebisa lithapo le lik'hebole. Air lenaihana fela ka mokhanni nke lehlakore, tse behiloeng ka litšehetso tšoana le conductors mohato.

Leha ho le joalo, ho vanishing hase kamehla netefatsa polokeho hlokahalang bakeng sa batho ba a kopana le tlhomamiso ea motlakase. Maemong a mang, dibakeng tse nang le kotsing ea ho vanishing, hammoho le botjha tšebeliso earthing sireletsang kapa shutdown polokeho eketsehileng e sebediswa. Sireletsang lithapo se nke lehlakore e hanetsoeng ho etsa kopo bakeng sa vanishing ea lisebelisoa tsa motlakase, ho fepa ka mela a mang, ha ba ntse ba ka retelehela theoha bakeng sa tokiso.

Ho le disebediswa tse sireletsang kenyeletsa qartulad potoloho, li amohele ho dutla jwale. The tshebediso ya le disebediswa tse tsena ka flats le ka ho ntlafatsa polokeho ea motlakase.
