Esimeni sezimboni, kungase kube nenqwaba yezinkinga ezingaba khona, futhi ukufakwa okufanele nezindlela zokufaka izintambo zibalulekile ukuze kuqinisekiswe ukuphepha ekukhiqizeni.Ngocwaningo lwanamuhla, sizohlola ndawonye ukuthi singaqinisekisa kanjani ukuphepha emkhiqizweni wezimboni.
1. Incazelo Yenkinga
Ikhasimende letheminali lalisebenzisa imojula yokuxhumana engu-485 i-CT-5321 ukuze ixhumane nesiguquli samaza.Bahlangabezane nesimo lapho amakhadi okuxhumana ayisithupha ku-inverter ye-frequency eshile ngokulandelana.Ngemva kokushintsha amakhadi e-inverter izikhathi eziyisithupha (isikhathi ngasinye okubangela ukutubeka), imojula yokuxhumana ye-CT-5321 ngokwayo yasha ngesikhathi sesithupha.
Ukuze uvimbele ukulahlekelwa okwengeziwe kwamakhasimende, onjiniyela be-ODOT bavakashele isayithi ukuze basize ekuxazululeni izinkinga.
2. Ukuxazulula inkinga esizeni
Ngemva kokubhekisisa ngokucophelela nokuhlaziya onjiniyela esizeni, lezi zinkinga ezilandelayo zihlonziwe:
(1) Kukhona amakhabethe okulawula ayi-14 esizeni, ngalinye liqukethe ama-inverter amabili kanye nemitha yamandla eyodwa adinga ukuxhumana ne-CT5321.
(2) I-GND ye-inverter yefrikhwensi ixhunywe kungqimba oluvikelayo lomugqa wesiginali.
(3) Lapho kuhlolwa i-wiring ye-frequency inverter, kwatholakala ukuthi umhlabathi wokuxhumana kanye nomhlabathi we-inverter awuzange uhlukaniswe.
(4) Intambo evikelekile yolayini wesignali we-RS485 ayixhunyiwe phansi.
(5) Izinqamuleli zetheminali ye-RS485 azixhunyiwe.
3. Ukuhlaziywa Kwembangela
Ngokusekelwe ekubonweni nasekuhlaziyweni kwesimo sendawo, unjiniyela unikeze imininingwane elandelayo:
(1) Izingxenye ezilimele namamojula awazange abonise izimpawu zokulimala okuvamile kokukhishwa kwe-electrostatic (ESD) noma ukuhlinzwa.Ngokungafani ne-ESD noma ukulimala kokuhlinzwa, ngokuvamile okungabangeli izingxenye ezishile, izingxenye ezishile ku-CT-5321 zazihlobene nedivayisi yokuvikela ugesi yechweba le-RS485.Le divayisi ivamise ukuba ne-DC breakdown voltage ecishe ibe ngu-12V.Ngakho-ke, kwatholakala ukuthi i-voltage ebhasini i-RS485 yayidlule i-12V, mhlawumbe ngenxa yokwethulwa kwamandla kagesi angu-24V.
(2) Ibhasi le-RS-485 lalinamadivayisi amaningi anamandla amakhulu namamitha wamandla.Uma kungekho ukuhlukaniswa okufanele kanye nokubekwa phansi, lawa madivayisi angadala umehluko omkhulu ongaba khona.Uma lo mehluko ongaba khona namandla amakhulu, kuyenzeka kwakheke iluphu kulayini wesignali we-RS485, okuholela ekubhujisweni kwamadivayisi kule loop.
4. Isixazululo
Ekuphenduleni lezi zinkinga zasendaweni, onjiniyela be-ODOT baphakamise lezi zixazululo ezilandelayo:
(1) Nqamula isendlalelo sokuvikela isignali ku-inverter GND bese usixhuma ngokuhlukile endaweni yesiginali.
（2） Gcoba isisetshenziswa se-inverter, hlukanisa umhlabathi wesignali, futhi uqinisekise ukuthi umhlaba uphansi ngendlela efanele.
(3) Engeza izinqamuleli zetheminali zokuxhumana kwe-RS485.
(4) Faka izithiyo zokuhlukanisa ze-RS-485 kumadivayisi ebhasi le-RS-485.
5. Umdwebo wokulungisa
Ukuqaliswa kwalezi zinyathelo zokulungisa ezingenhla kungavimbela ngempumelelo izinkinga ezifanayo ukuthi zingaphinde zenzeke, kuqinisekiswe izintshisekelo nokuphepha kwamakhasimende.
Ngesikhathi esifanayo, i-ODOT iphinde ikhumbuze amakhasimende ukuthi anake izinkinga ezifanayo ekwakhiweni nasekugcinweni kwezinhlelo zokuxhumana, ukuqinisa ukugcinwa nokuphathwa kwemishini, nokuqinisekisa ukuzinza nokuthembeka kwesistimu.
