KutloisisoLi-breaker tsa Potoloho tsa Hona Joale tse setsengKarolo ea Bohlokoa bakeng sa Polokeho ea Motlakase

Lefatšeng la polokeho ea motlakase, li-residual current circuit breaker (RCB) li bapala karolo ea bohlokoa ho sireletseng batho le thepa likotsing tsa liphoso tsa motlakase. Lisebelisoa tsena, tseo hangata li bitsoang lisebelisoa tsa residual current (RCD) kapa li-residual current circuit breaker (RCCB), li etselitsoe ho lemoha ho se leka-lekane ha current le ho bula potoloho ha phoso e fumanoa. Ho utloisisa hore na li-RCB li sebetsa joang le hore na ke hobane'ng ha li le bohlokoa ho ka thusa beng ba matlo le likhoebo ho netefatsa tikoloho e sireletsehileng ea motlakase.

Sehahlauli sa potoloho se setseng sa hona joale ke eng?

Sehahi sa potoloho sa motlakase se setseng ke sesebediswa sa motlakase se behang leihlo motlakase potolohong. Se bapisa kamehla motlakase o phallang ka hara terata e phelang le motlakase o kgutlang ho tloha terata e sa nke lehlakore. Maemong a tlwaelehileng, maqhubu ana a lokela ho lekana. Leha ho le jwalo, haeba ho hlaha phoso, jwalo ka potoloho e kgutshwane kapa motho a ama terata e phelang ka phoso, motlakase o mong o ka dutla fatshe. Ho se leka-lekane hona ho etsa hore motlakase o setseng o kgutlele potolohong, ho thibela ho tshoha kapa ho tuka ha motlakase.

Li-circuit breaker tse setseng tsa hona joale li sebetsa joang?

Li-circuit breaker tsa masala li sebetsa ho latela molao-motheo oa differential current. Ho na le transformer ka hare ho sesebelisoa e utloang hore current e phalla ka har'a lithapo tse chesang le tse sa nke lehlakore. Haeba phapang lipakeng tsa current tsena e feta moeli o reriloeng esale pele (hangata 30 mA ho netefatsa polokeho ea motho), circuit breaker ea masala e ea senyeha, e khaola motlakase ka har'a li-millisecond. Karabelo ena e potlakileng ea bohlokoa ho thibela kotsi e mpe kapa lefu le bakoang ke ho thunngoa ke motlakase.

Mefuta ea li-breaker tsa potoloho tse setseng

Ho na le mefuta e 'maloa ea li-residual current circuit breaker, e 'ngoe le e 'ngoe e na le morero o itseng:

1. Motlakase o Fetolanang: Mofuta ona ke wa dipotoloho tse nang le motlakase o fapanyetsanang feela (AC). Ke mofuta o tlwaelehileng haholo o sebediswang dibakeng tsa bodulo.

2. Mofuta wa A: RCB ena e lemoha diphoso tsa AC le tsa pulsating direct current (DC) mme e loketse dipotoloho tse nang le disebediswa tse nang le dikarolo tsa elektroniki, tse kang dikhomphutha le di-solar inverter.

3. Mofuta wa B: Di-RCB tsa Mofuta wa B di etseditswe dipotoloho tse ka tsamaisang motlakase o otlolohileng o boreleli mme hangata di sebediswa ditshebedisong tsa diindasteri, haholoholo tse kenyeletsang mehlodi ya matla a ntjhafatswang.

4. Mofuta oa F: Mofuta ona o kopanya likarolo tsa Mofuta oa A le Mofuta oa B, o sireletsa khahlanong le maqhubu a setseng a AC le DC, 'me o loketse mefuta e mengata ea lits'ebetso.

Bohlokoa ba li-circuit breaker tse setseng

Bohlokoa ba di-circuit breaker tse setseng bo ke ke ba feteletswa. Di bohlokwa ho ntlafatseng polokeho ya motlakase malapeng, dibakeng tsa mosebetsi le meahong ya setjhaba. Di-circuit breaker tse setseng di sireletsa maphelo ka ho thibela ho tshoha ha motlakase, haholoholo dibakeng tse nang le metsi, tse kang matloana le dikhitjhini. Di boetse di thusa ho thibela mello ya motlakase e bakwang ke dithapo kapa disebediswa tse fosahetseng.

Ho lekoa le ho hlokomeloa khafetsa ha RCB ho bohlokoa ho netefatsa hore e tšepahala. Liyuniti tse ngata li na le konopo ea teko ho lumella mosebelisi ho hlahloba ts'ebetso ea eona. Ho khothalletsoa hore RCB e lekoe bonyane hanngoe ka khoeli ho netefatsa hore e sebetsa hantle.

Ka kakaretso

Qetellong, di-circuit breaker tse setseng ke karolo ya bohlokwa ya ditsamaiso tsa motlakase tsa sejwalejwale, tse fanang ka tshireletso ya bohlokwa kgahlanong le dikotsi tsa motlakase. Ka ho utlwisisa hore na di-circuit breaker tse setseng di sebetsa jwang le mefuta ya tsona e fapaneng, batho ka bomong le dikgwebo ba ka etsa diqeto tse nang le tsebo mabapi le mehato ya bona ya polokeho ya motlakase. Ho tsetela ho di-circuit breaker tse setseng ha ho sireletse bophelo feela, empa hape ho sireletsa thepa, ho di etsa karolo ya bohlokwa ya ho kenya motlakase ofe kapa ofe.
