Uhlelo lokulawula lwe-injiniYakhiwe ngamaswishi, ama-fuse, ama-contactor amakhulu nasizayo, ama-relay, izinga lokushisa, amadivayisi okungenisa, njll., okuyinto eyinkimbinkimbi kakhulu. Kunezinhlobo eziningi zamaphutha, futhi ngokuvamile kuyadingeka ukuhlaziya nokuxazulula izinkinga ngosizo lwemidwebo yesimiso sokulawula.
Ngokuvamile, kufanele uqaphele ukugcina ingaphakathi nengaphandle lebhokisi lokulawula lihlanzekile futhi lomile, ngaphandle kwamanzi noma amabala kawoyela. Njalo (masonto onke) sebenzisa ifeni encane ukuze uphephule uthuli ezingxeni nasezithendeni nasemigqa ebhokisini, noma sebenzisa ibhulashi elicwiliswe esihlanzini sikagesi ukuze ulihlanze, ukuze ungathinti ukusebenza noma ukufudumala kwe-contactor kanye ne-relay. Kumabhokisi okulawula ane-drying resistor, ngokuvamile ungacimi i-heating switch ngokuthanda kwakho. Ibhokisi kufanele futhi libekwe phansi ngokwethembeka ukuze kuvinjelwe ukushaqeka kukagesi.
Hlola ukuqina kwezintambo nezikulufo ebhokisini njalo (njalo ngenyanga) ukuze uvimbele izintambo nezikulufo ukuthi zingakhululeki. Hlola ukuthi izingxenye ezifana namaswishi, ama-contactor, ama-relay, njll. zonakele noma zishile, nokuthi isimo sokusebenza sengxenye ngayinye kanye nemisebenzi yokuqala, yokuma, kanye neyokuxhumanisa kujwayelekile. Gcina oxhumana nabo abahambayo nabanganyakazi be-contactor bevaliwe futhi bexhumene kahle ukuze ugweme ukusha kwemoto ngenxa yokuxhumana okubi. Uma indawo yokuxhumana ilungile futhi imnyama nje, ungayisula ngendwangu eqinile. Ungapholi kalula ungqimba lwe-alloy olungashisi phezu kobuso, ngaphandle kwalokho kuzofinyeza impilo yoxhumana nabo; Uma indawo yokuxhumana isuswe kakhulu, ungasebenzisa iphepha lesihlabathi elithi “0″ ukuze libushelelezi. Oxhumana nabo abahambayo nabanganyakazi kudingeka balondoloze ukuxhumana komugqa noma indawo, hhayi ukuxhumana okuqondile. Isimo sokuxhumana singahlolwa ngokubeka iphepha phakathi koxhumana nabo abahambayo nabanganyakazi. Uma lingaboshelwanga kahle lapho lidonswa, kusho ukuthi oxhumana nabo noma isipilingi sidinga ukulungiswa noma ukushintshwa. Leli phuzu lidinga ukuthathwa ngokungathi sína. Ezimweni ezincane, ukuxhumana okubi kuzodala ukumelana okukhulu kokuxhumana (ugesi), okusho ukuthi umthwalo uyanda, okuholela ekukhubekeni kwe-relay yokuvikela ukunqwabelana ngokweqile. Ezimweni ezimbi kakhulu, kuzobangela ukuthi imoto isebenze ngendlela engenaso isigaba futhi ishe.
Uma ushintsha ama-relay nama-contactor, udinga ukunaka i-voltage yokusebenza ye-electromagnetic coil ukuze ugweme ukushisa i-coil ngenxa yokushintshwa okungalungile. Ngokuvamile, kune-24V, 220V kanye ne-380V. Kuma-relay esikhathi, ngaphezu kokunaka izidingo ze-voltage ye-coil, kufanele futhi ucacise iyunithi yokulungisa isikhathi (ihora, umzuzu, isekhondi) kanye nobubanzi be-time relay; ukuthi ngabe i-set current ye-thermal relay inengqondo futhi ifanelekile yini.
Kuma-motor aqalwa kusetshenziswa indlela ye-star-delta (Y-△) (ukubambezeleka kokuguqulwa kwemizuzwana emi-5), hlola ukuthi ukuqala kokuguqulwa kujwayelekile yini. Ngokuvamile, abakhiqizi banemithetho eqinile ngomjikelezo wokuqala wemoto (okungukuthi inani lokuqalisa ngomzuzu), futhi kuzoba namalebula esixwayiso ebhokisini lokulawula lokuqala ukukhumbuza abasebenzisi ukuthi bavimbele imoto ukuthi ingonakali ngenxa yokuqalisa njalo. Ngesikhathi esifanayo, futhi kuhloselwe ukuvimbela ezinye izingxenye zikagesi ebhokisini lokulawula lokuqala (njengeziqali zokuqalisa, njll.) ekushiseni nasekushiseni. Ngakho-ke, ezinhlelweni zokulawula izimoto eziqala futhi zima njalo noma ezinezikhukhula ezinkulu, umjikelezo wokuhlola nokulungisa kufanele ufinyezwe. Hlola njalo umsebenzi wokuvikela we-thermal overload relay (ungaphendula uhlelo olubomvu oluncane eduze kwalo) futhi inani lesenzo salo elibekiwe akufanele lidlule inani lamanje elilinganiselwe ku-nameplate yemoto ukuqinisekisa ukuthi lingadlala indima yokuvikela overload.
