Unodzivirira pasi: kuchengeteka eletropriborov

Unodzivirira ivhu anoonekwa kuti dzakagadzirirwa zvemagetsi kubatana pasi kurarama simbi, iyo, nokuda kuvhara ari mudziyo kwedzimba ave kurarama. Izvi zvinoitika panguva chero zvemagetsi kubatana kwete kugara esimbi echifananidzo simba chirimwa pamwe conductive okunze, kuti voltage zvingaitikawo Somuenzaniso, mheni.

With unodzivirira pasi anobvisa nengozi yemagetsi kuvhunduka kana anobata mhenyu zvikamu simbi muviri kana michina iyo, nokuda earthing akazviratidza kwakapa.

Anofanira kusiyaniswa kubva kushanda unodzivirira earthing, iro rakagadzirirwa ichishanda zvakanaka magetsi zvivako, uyewo kubva pasi kuidzivirira kubva mheni. By nokushanda kungasanganisira grounding kusatsigira dzenzvimbo ari jenareta ichitenderera simba transformer nezvimwe namano.

Nokuti grounding of mudziyo muchida kushandisa zviwanikwa zvishandiso uye zvinhu: simbi uye mapaipi mvura kuti havana Anti-ngura unhani, dzakakudzingai mapaipi vane putika kana zvinobata moto magasi kana mvura mvura. Akakodzera grounding kutungamirira wire sheathing, mavharuvhu uye zvinhu nekongiri Zvivako kana zvivako Akazadzisa zvesimbi. Just ziva kuti pasi rino rinofanira kuva chokuita nenyika. Uyewo dzakakodzera simbi dowels kana casing. Asi pachena aruminiyamu conductors uye waya sheathing chinorambidzwa kushandisa izvi zvinhu.

Pasina pasi zvakasikwa electrodes kana vane refu nemishonga inogona kushandiswa vari chakagadzirwa, izvo akasika rwokudzivirira grounding. Ivo vakaita hwendarira pakona zvikamu 5h5h0,5 masendimita kureba 2-3 metres, zvakaenzana pakati mapaipi simbi ine dhayamita 5 masendimita simbi dzeraundi zvikamu (urefu 5 m, dhayamita 12,0 - 14.0 mm). Used zvikamu (electrodes) inofanira achinyatsotaurira pasi ari kure nomumwe navamwe 3-5 metres, zvinhu zvose zvinofanira kwakabatana pakati simbi zviuno, chikamu muchinjikwa 40x4 mm.

The unobatanidza Pfekenura anoiswa mukati mugoronga kuti kudzika 0,70 metres, zvakafanana daro pachiso ndiyo okumusoro kumigumo electrodes. zvinhu zvose zvine chokuita ne Welding. Kuwanda electrodes rinowanikwa, inobva muvhu resistivity, electrode saizi, nechando chemvura kudzika uye zvimwewo.

Unodzivirira grounding zvemagetsi voltage kune zviuru B anogona kurongwa kushandisa zvivako simbi kweimba (pamberi akavimbika kubatana pakati redunhu zvinhu), wirings simbi sepombi, aruminiyamu wire sheaths, mapaipi esimbi (kunze nechepakati kudziyisa mugadziriro, uye tsvina Mapaipi). zviumbwe simbi, mabhokisi, zviruva uye busbars razero waya nematunhu (unodzivirira pasi uye kusatsigira) rinoshandiswawo.

Sezvo anodzivirira conductors razero chinorambidzwa kushandisa simbi uye dzakaonda anoshongwa vatungamirire waya uye netambo. Air AC ngavaparadzwe kuburikidza kwazvakarerekera kondakita, iyo panguva iyoyo zvitsigiso sezvo Pasika conductors.

Zvisinei, ichidzikira hapasi pave zvakakodzera kuchengeteka kuvanhu vaaisangana zvemagetsi kugadzwa. Mune zvimwe zviitiko, nzvimbo ine mikana ichidzikira, pamwe chete kunenge kushandiswa unodzivirira earthing kana kuchengeteka shutdown inoshandiswa. Protective waya kwazvakarerekera chinorambidzwa kushandisa kuti ichidzikira pamusoro midziyo yemagetsi, zvokudya dzimwe pemitsara, vanogona kutsauka kure yokuzvigadzirisa.

To anodzivirira mano zvinosanganisira redunhu namapoporodzi, vanoteerera kuti leakage ano. Kushandiswa mano aya Apartments kunogona kuvandudza magetsi kuchengeteka.
