Ubuchwepheshe bokuvikela i-Voltage zero-crossing, ukuze kuvikelwe i-relay emkhiqizweni.
Indlela yokubona ukuvikelwa yile: ukunikezwa kwamandla kukhoyili edluliswayo kulawulwa yi-microcomputer ye-single-chip, ngaleyo ndlela ilawula ukuvala koxhumana nabo abadluliswayo.Ngesikhathi esifanayo, iphoyinti lokucupha lenzeka ukuthi liyiziro kagesi ye-AC sine wave.Oxhumana nabo be-relay bavaliwe eduze nendawo ye-voltage enguziro, enganciphisa ukugoqa koxhumana nabo, ngaleyo ndlela ivikele i-relay kumthelela wamaza amakhulu.
Amathiphu Esithombe
Umugqa oluhlaza- igagasi elinesine lamanje elishintshanayo
Umugqa ophuzi -iphoyinti lokucupha ukuze oxhumene naye edluliselwe ukuvala
1-1 Iphoyinti lokucupha lisendaweni eyiziro-voltage
1-2 Iphoyinti le-Trigger liphuma ku-zero voltage
Isiphetho
1-1 Eduze kwephoyinti lokucupha kanye nendawo ye-voltage enguziro, lapho othintana naye evaliwe, ukulahlekelwa ngokomzimba kwamandla amanje okweqile kwe-relay kungagwenywa.
I-1-2 Uma othintana naye evaliwe, kukhona i-arc evela ku-voltage zero, khona-ke lapho othintana naye evaliwe, akukho ukuvikelwa kokudluliselwa.
Uchungechunge lwethu lomkhiqizo wokuvikela i-Voltage zero-cross oluhlobene:207C, 207HP, 207E,207F, 205C, 215C, 243C,217C, 251C, njll.
