KutloisisoLi-Breaker tsa Potoloho ea ho Dutla ha Lefatše tsa Mofuta oa BTataiso e Felletseng
Lefapheng la polokeho ea motlakase, li-residual current circuit breakers (RCCBs) li phetha karolo ea bohlokoa ho sireletseng basebetsi le lisebelisoa liphosong tsa motlakase. Har'a mefuta e fapaneng ea li-RCCB tse fumanehang 'marakeng, li-RCCB tsa Mofuta oa B li hlahella ka lebaka la likarolo le lits'ebetso tsa tsona tse ikhethang. Sengoloa sena se tla hlahloba litšobotsi, melemo le ts'ebeliso ea li-RCCB tsa Mofuta oa B, se fane ka kutloisiso e felletseng ea karolo ena ea bohlokoa ea motlakase.
Mofuta oa B RCCB ke eng?
Li-RCCB tsa Mofuta oa AB, kapa li-breaker tsa potoloho ea masala a Mofuta oa B, li sebelisoa ho lemoha le ho sitisa maqhubu a masala lipotolohong. Ho fapana le li-RCCB tse tloaelehileng, tse loketseng haholo-holo lits'ebetsong tsa motlakase o fapanyetsanang (AC), li-RCCB tsa Mofuta oa B li ka sebetsana le maqhubu a masala a motlakase a AC le a pulsating (DC). Sena se etsa hore li be molemo haholo lits'ebetsong tsa motlakase tsa sejoale-joale, haholo-holo ka ho amoheloa ho ntseng ho hola ha mehloli ea matla a nchafatsoang joalo ka liphanele tsa letsatsi le liteishene tsa ho tjhaja likoloi tsa motlakase.
Likarolo tse ka sehloohong tsa RCCB ea Mofuta oa B
1. Ho Lemoha Habeli ha Metsi: E 'ngoe ea likarolo tse hlahelletseng tsa li-RCCB tsa Mofuta oa B ke bokhoni ba tsona ba ho lemoha maqhubu a setseng a AC le DC. Tshebetso ena e habeli e li nolofalletsa ho fana ka tšireletso lits'ebetsong tse ngata, ho fihlela ho tenyetseha le ho tšepahala.
2. Ho ba le Kutlo e Phahameng: Li-RCCB tsa Mofuta oa B li etselitsoe ho khoptjoa ke maqhubu a tlase a setseng (hangata 30mA kapa 300mA). Ho ba le kutlo ena e phahameng ho bohlokoa ho thibela ho tšoha ha motlakase le ho fokotsa kotsi ea mollo oa motlakase.
3. Moralo o Monyenyane: Li-RCCB tse ngata tsa Mofuta oa B li nyane ka moralo 'me li ka kenngoa habonolo libotong tse fapaneng tsa switchboard ntle le ho nka sebaka se seholo haholo.
4. Ho latela maemo: Li-RCCB tsa Mofuta oa B li etsoa ho latela maemo a machaba a polokeho, ho netefatsa hore li fihlela litlhoko tse hlokahalang bakeng sa polokeho le ts'ebetso ea motlakase.
Melemo ea ho sebelisa RCCB ea Mofuta oa B
1. Polokeho e Ntlafaditsweng: Molemo o moholo wa ho sebedisa RCCB ya Mofuta wa B ke polokeho e ntlafaditsweng eo e fanang ka yona. Ka ho lemoha le ho sitisa mothapo o setseng, disebediswa tsena di fokotsa kotsi ya ho tshoha ha motlakase le mollo wa motlakase haholo, ka hona di sireletsa batho le thepa.
2. Ho feto-fetoha ha maemo: Li-RCCB tsa Mofuta oa B li loketse mefuta e mengata ea lits'ebetso, ho kenyeletsoa libaka tsa bolulo, tsa khoebo le tsa indasteri. Bokhoni ba tsona ba ho sebetsana le maqhubu a AC le a DC bo li etsa hore li be ntle bakeng sa litsamaiso tsa matla a nchafatsoang le ho kenya likoloi tsa motlakase.
3. Ho Latela Melao: Libaka tse ngata li na le melaoana e hlokang hore ho sebelisoe li-circuit breaker tsa mofuta oa B tse setseng lits'ebetsong tse itseng, haholo-holo tse amanang le litsamaiso tsa matla a letsatsi. Ho sebelisa lisebelisoa tsena ho netefatsa hore ho latela melao le maemo a motlakase a lehae.
4. Poloko ea Litšenyehelo tsa Nako e Telele: Le hoja litšenyehelo tsa pele tsa RCCB ea Mofuta oa B li ka ba holimo ho feta RCCB e tloaelehileng, bokhoni ba eona ba ho thibela liphoso tsa motlakase bo ka fella ka poloko e kholo ea litšenyehelo tsa nako e telele. Ka ho fokotsa kotsi ea tšenyo ea lisebelisoa le litokiso tse turang, RCCB ea Mofuta oa B ke letsete le molemo ho kenyeng motlakase ofe kapa ofe.
Tšebeliso ea RCCB ea Mofuta oa B
Li-RCCB tsa Mofuta oa B li sebelisoa hangata lits'ebetsong tse fapaneng, ho kenyeletsoa:
- Mekhoa ea ho Hlahisa Matla a Letsatsi: Ka ho tuma ha matla a letsatsi ho ntseng ho eketseha, li-RCCB tsa Mofuta oa B lia hlokahala ho sireletsa li-inverter tsa letsatsi le ho netefatsa polokeho ea lits'ebetso tsa letsatsi.
- Liteishene tsa ho tjhaja dikoloi tsa motlakase: Ha dikoloi tsa motlakase di ntse di tuma, di-RCCB tsa Mofuta wa B di bohlokwa ho sireletsa diteishene tsa ho tjhaja diphosong tse ka bang teng tsa motlakase.
- Lisebelisoa tsa Liindasteri: Mechini le lisebelisoa tse ngata tsa indasteri li hlahisa motlakase o tobileng, kahoo li-RCCB tsa Mofuta oa B ke likarolo tsa bohlokoa bakeng sa ho netefatsa polokeho libakeng tsa tlhahiso le ts'ebetso.
Ka bokhutšoane
Ka bokhutšoanyane, li-circuit breaker tsa mofuta oa B (RCCBs) ke karolo ea bohlokoa ea litsamaiso tsa polokeho ea motlakase tsa sejoale-joale. Bokhoni ba tsona ba ho lemoha maqhubu a setseng a AC le DC, kutlo e phahameng, le ho latela maemo a polokeho li etsa hore e be khetho e tšepahalang bakeng sa mefuta e mengata ea lits'ebetso. Ka kholo e tsoelang pele ea tlhoko ea litharollo tsa matla a nchafatsoang le likoloi tsa motlakase, bohlokoa ba li-circuit breaker tsa mofuta oa B (RCCBs) ho netefatseng polokeho ea motlakase bo ke ke ba nyenyefatsoa. Ho tsetela lisebelisoa tsena ha ho ntlafatse polokeho feela empa hape ho ntlafatsa katleho le ts'epo ea lisebelisoa tsa motlakase ka kakaretso.
