Esikhathini sobuchwepheshe bedijithali, amamitha ahlakaniphile avele njengethuluzi lokuguqula amandla okulawula amandla. Lawa madivayisi akali nje kuphela ukusetshenziswa kwamandla kodwa futhi ahlinzeka ngedatha yesikhathi sangempela kubo bobabili abathengi nezinkampani zezinsiza. Ukuqonda izingxenye zemitha ehlakaniphile kubalulekile ukuze ubambe ukuthi zisebenza kanjani kanye nezinzuzo ezinikezayo. Imitha ehlakaniphile ngokuyinhloko yakhiwe izingxenye ezintathu: ukushintsha, ukukala, kanye nokuhlanganisa. Ngaphakathi kwalezi zigaba, izingxenye ezimbalwa ezibalulekile zidlala indima ebalulekile, okuhlanganisa i-Magnetic Latching Relay, i-Current Transformer, ne-mangan shunt.
1. Ukushintsha: I-Magnetic Latching Relay
Enhliziyweni yokusebenza kwemitha ehlakaniphile iswishi, evame ukwenziwa lula yi-I-Magnetic Latching Relay(MLR). Le ngxenye ibalulekile ekulawuleni ukuhamba kukagesi ukuya nokubuya emitha. Ngokungafani nama-relay omdabu, adinga amandla aqhubekayo ukuze agcine isimo sawo, ama-relay amagnetic latching asebenzisa inkambu kazibuthe ukuze abambe indawo yawo. Lesi sici sibavumela ukuthi basebenzise amandla amancane, okubenza babe ukukhetha okuhle kwamamitha ahlakaniphile.
I-MLR ingashintsha phakathi kwezifunda zokuvula nokuvala ngaphandle kokudinga ukunikezwa kwamandla okuqhubekayo, okuzuzisa kakhulu ukonga kwamandla. Leli khono aligcini nje ngokunciphisa ukusetshenziswa kwamandla okuphelele kwemitha ehlakaniphile kodwa futhi lithuthukisa ukuthembeka kwayo. Uma kwenzeka ugesi unqamuka, i-MLR ingakwazi ukugcina isimo sayo, iqinisekise ukuthi imitha iyaqhubeka nokusebenza ngendlela efanele uma amandla esebuyile.
2. Isilinganiso: I-Transformer Yamanje kanye ne-Manganin Shunt
Ingxenye yokulinganisa yemitha ehlakaniphile ibalulekile ekukaleni ngokunembile ukusetshenziswa kwamandla. Izinto ezimbili eziyinhloko ezihilelekile kule nqubo i-Current Transformer (CT) kanye ne-mangan shunt.
I-Current Transformer iyingxenye ebalulekile evumela imitha ehlakaniphile ukuthi ilinganise amandla amanje ageleza kusekethe kagesi. Isebenza ngesimiso sokungeniswa kuka-electromagnetic, lapho okwamanje okuyinhloko kukhiqiza inkambu kazibuthe engenisa amandla alinganisiwe ekujikeni kwesibili kwe-transformer. Lolu shintsho luvumela ukulinganisa okuphephile nokunembile kwamagagasi aphezulu ngaphandle kwesidingo sokuxhuma ugesi okuqondile.
Ama-CTs anenzuzo ikakhulukazi kumamitha ahlakaniphile ngoba anganikeza idatha yesikhathi sangempela ekusetshenzisweni kwamandla, okuvumela abasebenzisi ukuthi baqaphe amaphethini abo okusebenzisa. Lolu lwazi lungaba wusizo kubo bobabili abathengi nezinkampani zezinsiza, njengoba luvumela ukuphathwa okungcono kwamandla nokubikezela.
Manganin Shunt
Enye ingxenye ebalulekile yokulinganisa yi-manganin shunt. Lolu cingo lusetshenziselwa ukukala ukwehla kwamandla kagesi endaweni eyaziwayo yokumelana, okuvumela imitha ehlakaniphile ukuthi ibale amandla amanje agelezayo kwisekhethi. I-Manganin, ingxubevange yethusi, i-manganese, ne-nickel, ikhethwa ngenxa ye-coefficient yayo yokushisa ephansi yokumelana, okuqinisekisa ukunemba okuphezulu ezilinganisweni.
I-mangan shunt isebenza kahle kakhulu kumamitha ahlakaniphile ngoba ikwazi ukuphatha imisinga ephezulu ngenkathi igcina ukuzinza nokunemba. Lokhu kunemba kubalulekile ekunikezeni abathengi idatha ethembekile ekusebenziseni kwabo amandla, okungaholela ezinqumweni ezinolwazi mayelana nokusetshenziswa kwamandla nokonga izindleko.
3. UMkhandlu: Ukuhlanganiswa Kwezingxenye
Ukuhlanganiswa kwemitha ehlakaniphile kuhilela ukuhlanganiswa kweswishi, izingxenye zokulinganisa, nokujikeleza okwengeziwe okusiza ukuxhumana nokucubungula idatha. Lo mhlangano uklanyelwe ukuqinisekisa ukuthi zonke izingxenye zisebenza ndawonye ngaphandle komthungo ukuze zinikeze ulwazi olunembile nolufike ngesikhathi.
Ukuhlanganiswa kwalezi zingxenye kuvumela amamitha ahlakaniphile ukuthi axhumane nezinkampani zezinsiza ngokusebenzisa amanethiwekhi angenawaya. Leli khono lokuxhumana liwukuthuthuka okuphawulekayo ngaphezu kwamamitha avamile, obekudinga ukufundwa mathupha. Ngamamitha ahlakaniphile, idatha ingadluliswa ngesikhathi sangempela, okuvumela izinsiza ukuthi ziqaphe amaphethini okusetshenziswa kwamandla, zibone ukuphela, futhi zilawule izinsiza ngempumelelo kakhudlwana.
Ngaphezu kwalokho, ukuhlanganiswa kwamamitha ahlakaniphile kuvame ukufaka izici ezithuthukile njengokutholwa kokuphazamiseka, okuxwayisa izinkampani zensiza ngokukhwabanisa okungaba khona noma ukusetshenziswa okungagunyaziwe. Lesi sendlalelo esingeziwe sokuphepha sibalulekile ekugcineni ubuqotho besistimu yokusabalalisa amandla.
Isiphetho
Kafushane, imitha ehlakaniphile iqukethe izingxenye ezintathu eziyinhloko: ukushintsha, ukukala, nokuhlanganisa. I-Magnetic Latching Relay isebenza njengesishintshi, ihlinzeka ngokulawula okusebenzayo kokugeleza kwamandla. Izingxenye zokulinganisa, ezifaka i-Current Transformer ne-mangan shunt, ziqinisekisa ukugadwa okunembile kokusetshenziswa kwamandla. Okokugcina, umhlangano uhlanganisa lezi zingxenye, ovumela ukuxhumana nokucubungula idatha okuthuthukisa ukuphathwa kwamandla.
Njengoba umhlaba uphokophele ezenzweni zamandla ezimeme kakhudlwana, amamitha ahlakaniphile azodlala indima ebalulekile ekusizeni abathengi nezinkampani ezisizayo ukuthi zisebenzise amandla ngokugcwele. Ukuqonda izingxenye ezakha lawa madivayisi kubalulekile ukuze ubonge umthelela wazo ekusebenzeni kahle kwamandla nokuphatha. Ngokuthuthuka kwezobuchwepheshe, ikusasa lamamitha ahlakaniphile libukeka lithembisa, livula indlela yezixazululo zamandla ahlakaniphile.
