Ngokujiwuzisa esi siphatho sime nkqo kwaye usijikelezise ngasekunene kwe-50º, indlela yokusebenza yokutshintsha idityanisiwe ukusuka kwishaft ephumayo. Xa kuqhawulwe, umqhubi wokutshintsha unokusebenza ngesandla okanye ngombane ngaphandle kokusebenzisa i-circuitwitch, kunye nesixhobo sokuhamba (ukuba sinikezelwe) sinikezelwa ngokungasebenzi. 1 Xa idityanisiwe, i-shaft ye-switchoperator output ithintelwe ukuba ihambe ngesixhobo sokutshixa ngomatshini ngaphakathi kwendawo evaliweyo yomsebenzisi.
Ngexesha lecandelo eliphakathi lokuhamba kwe-handle handle, elibandakanya indawo apho ukuchithwa kwangempela (okanye ukubandakanyeka) kwendlela yokudibanisa yangaphakathi kwenzeka, umthombo we-motorcircuit ukhokelela unqanyulwe okwethutyana, kwaye zombini ukuvulwa kunye nokuvala i-motor contactors zivaliwe ngomatshini kwi-Open position. Ukuhlolwa okubonwayo ngefestile yokuphonononga kunceda ukuqinisekisa ukuba indlela yokudibanisa yangaphakathi ikwindawo eDityanisiweyo okanye iDityanisiwe. Jonga uMfanekiso 3. Isiphatho sokuqhawula sisenokutshixwa kuyo nayiphi na indawo.
Ukudibanisa kulula. Akunakwenzeka ukwenza isibini "esivulekileyo" i-circuit-switch kunye nomqhubi wokutshintsha kwindawo evaliweyo, okanye ngokuphambene. Ukudibanisa kunokwenzeka kuphela xa i-shaft-opharetha yokukhupha i-shaft ihambelana ngomatshini kunye ne-switchoperator mechanism. Olu ngqamaniso lufumaneka ngokulula ngokusebenza ngesandla okanye nge-elektroniki umqhubi wokutshintsha ukuzisa kwindawo efanayo eVulekileyo okanye eValiweyo njenge-circuit-switch. Izalathi zesikhundla sokutshintsha, viewd ngefestile yokuphonononga, bonisa xa uqikelelo lwendawo ethi Vula okanye eValiweyo ifunyenwe. Jonga umzobo 3. Emva koko, ukuhambisa umqhubi wokutshintsha kwindawo echanekileyo yokudibanisa, isibambo sokusebenza semanuwali siphendulwe kude kube iidramu ze-positionindexing zihambelana ngokwamanani.
- Kuphela isixhobo sohambo lwe-shunt sinikezelwa ngokungasebenziyo. Umqhubi wokutshintsha usenokuvulwa ngokusebenzisa isekethe ye-protectionrelay yomsebenzisi. Ngaloo ndlela i-checkout "ekhethiweyo" yeskimu sokukhusela inkqubo inokwenzeka nangaliphi na ixesha.
Travel-Limit Switch Uhlengahlengiso
Ukutshintshela umda wokuhamba udityaniswe nemoto ulawula ubungakanani be-output-shaft rotation kwindlela yokuvula nokuvala. Ibandakanya abafowunelwa abathandathu abaqhutywa yi-cam-actuated rollers. Ukubekwa kweekhamera zokubandakanya ngokufanelekileyo ii-roller kufezwa ngeendlela ezimbini zeediski zokuhamba, enye i-stroke yokuvula kunye neyokuvala i-stroke.
Idiskhi nganye yomda wokuhamba ilungelelaniswa ngokuchanekileyo ngokusebenzisa ikhamera yokuzivalela entwasahlobo. Ukuvula ukuhamba kulungelelaniswa ngokuphakamisa kunye nokuguqula i-disc ye-openstroke yokuhamba-mda wokuhamba kwindawo efunekayo kwi-plate yesalathisi ngelixa ubambe i-handwheel. Ngokufanayo, ukuvala ukuhamba kulungelelaniswa ngokunciphisa kunye nokuguqula i-disc yokuvala i-stroke ye-travel limit disk kwindawo efunekayo kwi-plate yesalathisi ngelixa ubambe i-handwheel.
Ukwenza idiskhi ye-travel-limit ye-open-stroke ye-travel-limit disc yenza i-contact yokuvula ivule, ethi emva koko ikhuphe amandla kwi-solenoid yokukhutshwa kwe-brake ukumisa ukuhamba kwendlela. Ukusebenzisa idiskhi yomda wokuvala istroke kuphelisa amandla isinxibelelanisi esivalayo, nto leyo ephinda ikhuphe amandla kwi-solenoid ye-brakerelease ukumisa intshukumo yomatshini.

Ibonelela abafowunelwa abasibhozo abalungelelanisiweyo abafakwe ngaphambili kwiibhloko ze-terminal (abafowunelwa abathandathu bayafumaneka ukuba umqhubi wokutshintsha unikwe indawo ekhethiweyo ebonisa lamps, isimamva senani lekhathalogu “-M”). Aba bafowunelwa babonelelwe ukuze iisekethe zangaphandle zisekwe ukujonga ukusebenza kokutshintsha.
Njengeediski zomda wokuhamba, unxibelelwano ngalunye oluncedisayo lunekhamera yokuzimela e-spring-biased cam evumela ukulungiswa okuchanekileyo kokubandakanyeka kwe-cam-roller kwindawo efunwayo kumjikelo wokusebenza. Isikhundla seCam sihlengahlengiswa ngokunyusa (okanye ukuthoba) ikhamera ukuya ngasentwasahlobo ekufutshane kwaye iyijikelezise kwindawo oyifunayo. Jonga umzobo wesi-5. Iswitshi eyongezelelweyo yeepali ezine edityaniswe nenjini kunye nokusetyenziswa kolwakhiwo olufanayo kuyafumaneka njengokhetho (inombolo yekhathalogu isimamva "-Q")
Utshintsho oluncedisayo olongezelelweyo oludityaniswe kwi-circuitswitcher lukwakhona njengokhetho kwaye lunokubonelelwa ukuze abafowunelwa bangaphandle bamiselwe ukujonga imisebenzi ye-circuit-switch. Olu tshintsho oluncedisayo lukwasebenzisa iikhamera ezizitshixayo ze-springbiased. Inokuthi inikwe kwinguqu yeepali ezisibhozo (inombolo yekhathalogu isimamva "-W") okanye kwi-12-pole version (inombolo yekhathalogu isimamva "-Z").
Ubonelelo lweSixhobo se-S&C Shunt-Trip
I-S&C Mark V Circuit-Switchers exhotyiswe ngesiXhobo se-S&C Shunt-Trip esizikhethelayo sibonelela ngomjikelo we-8 ubuninzi bexesha lokuphazamisa. Olu phazamiseko lwesiphaluka olukhawulezayo luququzelela ukusetyenziswa kwee-circuitwitchers kwicala eliphambili le-transformers ukwenzela ukukhusela abaguquli kwiimpazamo zangaphakathi, ukwenzela ukhuseleko lwe-backup multiple-contingency for overloads kunye neempazamo zesibini, kunye nokukhusela iisekethe zecala lomthombo kuzo zonke iintlobo zeempazamo ze-transformer.
Xa isixhobo se-shunt-trip sisebenza, i-solenoid enesantya esiphezulu evalelwe kwizindlu ezingenwa yimozulu kwisiseko ngasinye sepali ijikelezisa i-lowinertia ebhityileyo egqunyiweyo kwi-15 degrees. Oku kukhupha amandla agciniweyo ngaphakathi kwengqondo yokuvula ngesantya esiphezulu sesiphazamisi.
Uhlobo lwe-CS-1A i-Switch Operators, enikwe i-Mark V Circuit-Switchers exhotyiswe ngesixhobo sohambo lwe-shunt-trip, inokubonelelwa ngonxibelelwano olukhethiweyo lwe-shunt-trip kunye ne-time-delay relay (inombolo yekhathalogu isimamva "-HP"). Olu phawu olukhethwayo lunciphisa ukutyhoboza kolawulo ngokunika amandla isixhobo sohambo lwe-shunt kunye nemoto yokusebenza ngokulandelelana, ngaloo ndlela ivumela ukusetyenziswa kocingo lolawulo olunobungakanani obuncinci phakathi kokhuseleko lomsebenzisi okanye isilayidi solawulo kunye nomsebenzisi wokutshintsha.
Ulawulo lolandelelwano
Ukusebenza okuchanekileyo kwe-Mark V Circuit-Switchers kuxhomekeke ekuhlawuleni nasekubambeni umthombo wamandla ogciniweyo ngaphakathi kwengqondo nganye njengoko iiblawudi zokuqhawula zisiya kwindawo eVulelekileyo ngokupheleleyo. Ithagethi yokuphazamiseka ebekwe kwicala lendlu nganye yobuchopho ibonakala ityheli xa isiphazamisi sivulekile. Ithagethi ibonakala ingwevu (eqhelekileyo) xa isiphazamisi sivaliwe.
Iziphazamisi akufuneki zivuleke ngelixa iiblade zikwindawo eValiweyo. Ukuvala iziphazamisi, i-circuit-switcher kufuneka ivulwe ngokupheleleyo kwaye iphinde ifakwe kwakhona. Ngesi sizathu, umqhubi wokutshintsha udibanisa isiphaluka solawulo esenza ukuba umqhubi wokutshintsha abuyele ngokuzenzekelayo kwindawo eVulekileyo nanini na xa i-voltage yolawulo-mthombo.tage ibuyiselwa ngelixa umqhubi wokutshintsha ukuyo nayiphi na indawo phakathi kokuvula ngokupheleleyo kunye nokuvala ngokupheleleyo.
Esi senzo senzeka nokuba leliphi icala ebesisebenza kulo phambi kokulahleka kwevolthitage. Esi sijikelezo solawulo sisixhobo esakhelwe ngaphakathi ukukhusela i-circuit-switcher ukuba ivalwe ukusuka kwindawo evulekileyo yokuvula emva kokuba iziphazamisi zikhubekile zivulekile.
