Inkqubo kunye nendlela yokujonga uhambo kunye nokuvala kwakhona ukusilela kwe-air circuit breaker(ACB)

I-air circuit breaker(I-ACB) ukukhubeka, ukuvala kwakhona akuphumelelanga

1. Okokuqala jonga ukuba ngaba iI-air circuit breakerayikhubekanga ngempazamo

Uhambo olungekho ngengozi luthetha uhambo olungenayo isiphaluka esifutshane okanye impazamo yomthwalo ogqithisileyo.Kukho izizathu ezininzi zokuI-air circuit breakerhayi ukuvala.Okokuqala, kuyimfuneko ukugqiba uhambo olubangelwa isiphaluka esifutshane kunye nokugqithiswa, okanyei-air circuit breakerngokwayo okanye iluphu yolawulo inempazamo.Fumana kwaye ubone ukuba isekethe inempazamo okanye iisiqhekeza-moyayona ngokwayo iyimpazamo.
Emva kokumisela impazamo ye-air circuit breaker, khupha i-breaker circuit (ibhekisela kwi-idrowa uhlobo air circuit breaker) ukwenzela ukuhlolwa.

2. I-Universal type breaker yesekethe ukulungisa ingxaki eqhelekileyo

(1) I-breaker circuit ayinakuvalwa ngenxa yokulahlekelwa kwamandla kwisixhobo sokuhamba nge-undervoltage.Ukuba i-voltage iphantsi kakhulu okanye i-coil ye-undervoltage device yokukhwela iphelile amandla, i-breaker circuit iya kukhwela kwaye ayikwazi ukuphinda ivalwe.Ezi meko zine zilandelayo zinokubangela icoil ye-undervoltage tripper ilahlekelwe amandla.

• (1) I-fuse yesekethe yokhuselo ivuthelwe, efana ne-RT14, ekhokelela ekuvalelekeni kwesekethe kunye nokulahleka kwamandla e-coil yokukhubeka yesixhobo sokukhubeka sangaphantsi kombane;
• (2) Iqhosha lokuvala, i-relay contact, i-circuit breaker encedisayo yoqhagamshelwano olubi, umonakalo wecandelo, kunokukhokelela ekuvalelekeni kwesekethe, ukukhubeka kombane wekhoyili;
• (3) Intambo yokudibanisa kwi-loop yaphukile, kwaye i-crimping screw ikhululekile kwaye ikhululekile, eya kukhokelela kwisekethe ivaliwe, kwaye i-coil ekhubekayo inqanyuliwe;
• (4) Ngenxa yekhoyili yokukhutshwa kwe-undervoltage ikwimeko yokusebenza yombane ixesha elide, ungcoliseko lokusingqongileyo kunye nezixhobo aziguquguquki, okanye umsantsa womoya phakathi kombindi kunye nesixhobo sokuzikhusela sikhulu kakhulu, kulula ukuwenza. yenza i-current ikhulu kakhulu kwaye iholele ekukhululeni ukufudumeza kwekhoyili kunye nokutshisa, ulahlekelwe ngumsebenzi wekhoyili yokukhulula.
• Isiphoso esingentla ngokuqwalasela kunye nokuhlola okulula kunye novavanyo lunokwenza isigwebo esichanekileyo, ngoko ke xa kufunyenwe iphoso kufuneka kupheliswe ngexesha, njengokudibanisa okukhululekileyo ukuqinisa, umonakalo wecandelo kunye nokutshiswa kwekhoyili efuna ukutshintshwa.

(2) Ukungaphumeleli kwenkqubo yomatshini, okubangela ukuba i-breaker circuit ayikwazi ukuvala.Emva kokukhubeka kunye nokuvala indlela yokusebenza ye-circuit breaker amaxesha amaninzi, umatshini unxitywe kakhulu kwaye ezi mpazamo zilandelayo zingenzeka.

• (1) Ukunxitywa kwendlela yokuhanjiswa kweMoto, efana ne-ME switch worm gear, umonakalo weentshulube, ayinakukwazi ukuqhuba i-buckle ye-circuit breaker yokusebenza, vala.Igiya yeentshulube, ukutshintshwa kweentshulube kuntsonkothile ngakumbi, imfuno yolondolozo lobungcali.
• (2) Ukunxitywa kwesixhobo sokuhamba simahla, ukwenzela ukuba i-breaker sekethe kunzima ukuyibopha, ukukhubeka lula, ngamanye amaxesha kunyanzeliswe ukuba ibophe, kwimeko yokungcangcazela, uhambo;Ngamanye amaxesha emva kwe-buckle, i-buckle evaliweyo iya kutyibilika.Ngeli xesha, i-screw yokulungelelanisa kufuneka ijikelezwe ukuze ilungelelanise indawo ehambelanayo ye-shaft ye-half shaft kunye ne-buckle ye-tripping, ukwenzela ukuba indawo yoqhagamshelwano ibe malunga ne-2.5mm2, kwaye iindawo ezihambelanayo kufuneka zitshintshwe xa kuyimfuneko.
• (3)Imithombo yogcino lwamandla yendlela yokusebenza ayilungile.Imithombo yokugcinwa kwamandla okuphulwa kwendlela yokusebenza ikhulula okanye ilahlekelwe yi-elasticity yayo emva kokunwebeka okuninzi, kwaye amandla okuvala ayancipha.Xa uvala, i-four-bar mechanism ye-breaker circuit ayinakutyhalelwa kwindawo yokufa, kwaye i-mechanism ayikwazi ukuzigcina kwindawo yokuvala.Ngoko ke, i-breaker circuit ayikwazi ukuvalwa ngokuqhelekileyo.Umthombo wokugcina kufuneka utshintshwe.
• (4)Umatshini wokusebenza awuguquguquki, kwaye kukho into ebambekayo.Ngenxa yokuba olu hlobo lwe-breaker circuit aluvalwanga ngokupheleleyo, ukuba i-screws, i-nuts kunye nezinye izidumbu zangaphandle zishiywe ngengozi kwindlela yokusebenza, ukwenzela ukuba i-circuit breaker operation ibambe i-phenomenon, iya kuchaphazela ukuvala;Ukongeza, ukujikeleza kunye neendawo ezityibilikayo zokungabikho kwegrisi yokuthambisa, indawo yokugcina amandla yokuvula indlela yokusebenza ikhubazekile kancinane, kwaye i-breaker circuit ayikwazi ukuvala i-brake.Ngoko ke, xa kwenzeka ukungaphumeleli okungentla, ngaphezu kokujonga indlela yokusebenza, akukho mahluko, kodwa kunye nokujova igrisi yokuthambisa kwi-rotation kunye ne-sliding part.
