"Qala-stop" inkinobho izindlu. Indlela ukuxhuma?

Zokulawula "qala-stop" ivamile impela emsebenzini. Lezi amadivayisi asetshenziswa ukusebenzisa imishini. Ngaphambi oxhumanisa imodeli kubalulekile ukwazi uhlobo inkinobho. Kukhona ukuthintana kanye ukuhlela kabusha engenantambo. Ngaphezu kwalokho, udlala indima isilawuli, esetshenziswa phakathi nokufaka. Ukuze siqonde impikiswano, kuba okokuqala kudingekile ukuba ucabangele ejwayelekile wiring Umdwebo inkinobho.

wiring idayagramu

Standard uxhumano wesifunda inkinobho isiqalo-stop kuhilela ukusetshenziswa sokuvalwa contactor. Ashaywe ifaniswe nge conductivity ka 4.5 cm. Abanye ochwepheshe ukufaka kudivayisi ngqo ngokusebenzisa edluliselwe. It kuphela olunezintambo ukulungiswa efanelekayo. Uma abeke le divayisi ne comparator, flip-flop isetshenziswa ne insulators. I wire wokuqala kusukela inkinobho uvala ikhoyili edluliselwe. Contactor ihlinzekwa ngqo transceiver.

Ukucutshungulwa QF1

Ixhuma nge ukuziqalela inkinobho "ukuqala-stop" wenziwa udlulisela. Uma sicabangela isikimu nge isilawuli yezintambo, le thyristor isetshenziswa ngezigaba ezimbili. Ngqo capacitor liyadingeka 4 PF. Ochwepheshe bathi nabalawuli ingasetshenziswa amabili kuya kwamathathu okukhiphayo. Nokho, kulesi simo ukuthi okuningi kuncike uhlobo rectifier. Ngo imishini ezivamile lifakwe nenkokhiso omuhle.

I ukumelana naye kulingana engengaphansi kwengu ohms 50. Kubalulekile futhi ukwazi ukuthi uye walungiselela ipuleti lokuvala. Kulesi simo, oxhumana lokuqala inkinobho ayanikezelwa kuya edluliselwe. Kulokhu isilawuli uvala isigaba sokuqala. Ngaphambi kokuhlola ukumelana kubalulekile ukuhlola wesifunda phansi. Liphinde belulekwa ukuxhuma yisivikelo. Oxhumana we inkinobho wesibili yanikezwa olwandisa. I isimame iyadingeka ukuxhuma uhlobo wave.

Umdwebo nge actuator engelapheki

temusho engelapheki muva nje njalo. Xhuma inkinobho "ukuqala-stop" ovunyelwe ukwenza ngqo ngokusebenzisa edluliselwe. Kulokhu, flip-flops kungukuthi isicelo. Kufanele kuphawulwe ukuthi ukufakwa switch kungenziwa ngokusebenzisa comparator. Esimweni esinjalo sizokwazi ukufaka isilawuli. Ngaphezu kwalokho ukukhwezwa isimame.

Ochwepheshe bathi Converter isetshenziswa uhlobo bi Ohlangothi. Ixhuma Ungowokuqala okuxhunyanwa naye eyalo isigaba sokuqala. Kufanele kuphawulwe ukuthi circuit capacitors asetshenziswa uhlobo capacitive. Ngakho-ke, isimame kudingeka uhlobo olulodwa-pole. Uma sicabangela omoya ezimbili isiteshi, oxhumana naye Wegazi kuphela asetshenziswa kubo. I izishintsha evaliwe Kulokhu nge ebheke. Oxhumana yokuqala ingibeke ngaphansi sesibili.

Ukusetshenziswa temusho Goal

Ixhuma inkinobho isiqalo-stop nge contactors Goal Kwenziwa noma ngaphandle converters. Uma sicabanga ukhetho lokuqala, capacitors Kusetshenziswa Semiconductor insulators. Ngqo ukusetshenziswa ku emazombezombe 15V ukumelana Inkomba kuso akufanele kube ngaphansi kuka-30 ohms.

A comparator isetshenziswa ukushintshela ku Imiphumela ezimbili. Oxhumana lokuqala ivaliwe by isigaba sokuqala. I isimame kulokhu kufanele kube kule sikhundla evulekile. Ezinye ukushintshwa zidayiswa enezihlungi. Futhi uzinake wukuthi kukhona contactors nge Unijunction resistors.

Iziyalezo temusho PML-1100 Series

Indlela kokuxhuma "ukuqala-stop" inkinobho? Kuyinto pretty elula ukwenza nge thyristor siteshi. Drives yedivayisi lemifanekiso ezimbili ezikhethiwe. Ukumelana Inkomba, ngokwesilinganiso elilingana 55 ohms. Dynistors ogunyaziwe ukusebenzisa uhlobo bi Ohlangothi.

Ochwepheshe bathi kubalulekile ngokuphelele uhlanze contactors. Ngaphezu kwalokho, kufanele kuphawulwe ukuthi babashayeli kufanele kahle ngci. Oxhumana lokuqala uvaliwe sesibili. I conductivity yochungechunge, ngokwesilinganiso elilingana 4.5 cm. I olwandisa isetshenziswa uma ufaka uhlobo broadband.

Ixhuma ukuziqalela Modular

Okokuqala wire Modular ixhunyiwe kuphela inkinobho "ukuqala-stop". Kulokhu, lo converters avame ukusetshenziswa ne adapters. Oxhumana lokuqala inkinobho ivaliwe by isigaba sokuqala. Ngqo yisivikelo isethelwe eside. I rectifier thyristor isetshenziswa. Nokho, kulesi simo ukuthi okuningi kuncike endleleni isilawuli. Uma sicabanga imodeli ku okukhiphayo ezintathu, banayo ababili dynistor. Oxhumana lokuqala inkinobho ivaliwe ngu sesibili. A isimame aboshelwe komunye umkhawulo zokuhlunga.

Yokuqala version evulekile

Inkinobho "qala-stop" e izindlu ukuvula contactor ixhunyiwe ngocingo inhlamvu. I transceiver isetshenziswa eyodwa noma ngaphezulu Wegazi. Lapho oxhumanisa inverter iyenziwa ukumelana kusukela capacitor ayikwazi ukumelana umthwalo lamanje.

Lokhu kukhetha ngokwesilinganiso elilingana 33 ohms. Uma emithathu isikhundla ukushintsha isilawuli, le transceiver isebenzisa uhlobo multi-umzila. Conductivity kufanele kube mayelana 4.5 cm. Ngaphezu kwalokho, kubalulekile ukuqaphela ukuthi contact inkinobho yesibili ivaliwe by isigaba sokuqala. Ochwepheshe bathi umqhubi phezu plate kumele uqale ukucindezela ngokucophelela. I isolator isethelwe lo olwandisa. Uma solder-ngokusebenzisa transceiver, izihlungi ezimbili ezisetshenziswa wesifunda.

temusho Ixhuma ivaliwe ukubulawa

Inkinobho "ukuqala-stop" idatha temusho efakwe ngqo ngokusebenzisa edluliselwe. I transistors zikhethwa le njongo a conductivity ongaphakeme. Ngaphambi oxhumanisa izingxenye ihlolwe okukhipha impedance. Wathi ipharamitha yesifunda kumele singeqi 45 ohms. Ngezinye sindisa okusezingeni eliphezulu kunconywa ukushintsha ukuhlunga. Futhi uzinake ukuthi izinkinga singenzeka ngenxa conductivity eliphansi Transistor. Oxhumana lokuqala inkinobho ivaliwe by isigaba sokuqala. IStabilizer wesifunda isetshenziswa kuphela eyodwa-pole hlobo. Ngokweqile inkomba embundwini umbono ingxenye ilingana okungenani 5 A.

Uxhumano ngokusebenzisa unijunction inkinobho inhlamvu

Unijunction icuphe abe conductivity eliphezulu. Insulators kumadivayisi akhethwe uhlobo bidirectional. inkinobho Simple "ukuqala-stop" Kumiswa ngqo nge udlulisela. Kufanele kuphawulwe ukuthi idivayisi ukufakwa zingenziwa ngokusebenzisa control unit. Uma sicabanga esiku yasungula umshini wokugaya, le transceiver isebenzisa uhlobo olulodwa-siteshi. Oxhumana lokuqala inkinobho wumnikezeli sesibili. Kulesi sigaba kubalulekile ukuhlola impedance okukhipha. Lapho ukulayisha 3 A conductivity akumele leqe 5.5 Bheka.

Uma usebenzisa abalawuli okuqinile-state, ukumelana ngokwesilinganiso elilingana 55 ohms. Ngaphezu kwalokho, kubalulekile ukwazi ukuthi ngokuvamile ukusetha contactors sokuphetha kanye nasemigwaqweni ezimbili. Kulesi simo, yisivikelo isethelwe Transmitter. Ngakho, sindisa ekugcineni idlula 6 A. Ashaywe ngokuvamile isetshenziswa olwandisa. Xhumana nabo kungase kuhlotshaniswe ngqo.

trigger Isicelo dvuhperehodnyh

Kaningi, "ukuqala-stop" inkinobho isethwe izimbangeli ezimbili period. Basuke exhunywe nge edluliselwe supply 12 V amandla isetshenziswa uhlobo ishayela. Udlulisela zingasebenzisa 4 A. inkinobho inhlamvu igibele ukufakwa transducer. ukumelana okukhipha elilingana 40 ohms. Uma isici kakhulu kushisa kakhulu ke inkinga itholakala inhlamvu ukuminyana. Ngenxa yale njongo, kuphela capacitors wire. Ngakho comparators zivaliwe by isigaba sokuqala.

Amadivayisi nge abalawuli capacitive kungenziwa exhunywe kuphela ngokusebenzisa dynistors. Kulokhu, ukushintshwa efanelekayo ezintathu kuphela ekhishwayo. I yisivikelo ogibele wesifunda okukhiphayo. Kulokhu, Converter kuyakhethwa blocker bidirectional. I voltage okukhiphayo of wesifunda imayelana 15 V. Kulokhu, isici umthwalo kumele singeqi 4 A. Uma isilawuli dipole, adaptha singasebenza okukhiphayo ezimbili. Oxhumana lokuqala inkinobho ivaliwe ngu sesibili. I ukumelana kumelwe ibe ngaphansi kuka-30 ohms.
