YC9VA Voltage Protection Relay
Maonekedwe ndi Kukula kwa Keypad
Kufotokozera
YC9VA voliyumu ndi mawonekedwe amakono owonetsera ndi chipangizo chowunikira magetsi opangidwa ndi microprocessor pamanetiweki agawo limodzi la AC kuti ateteze zida zamagetsi kumagetsi owonjezera.Chipangizocho chimasanthula voteji yayikulu ndikuwonetsa mtengo wake wapano pa chizindikiro cha digito.Katundu amasinthidwa ndi electromagnetic relay.Wogwiritsa akhoza kukhazikitsa mtengo wamagetsi omwe alipo komanso kuchedwetsa nthawi kudzera pa batani.
Mtengowo umasungidwa mu kukumbukira kosasunthika.Mawaya a aluminiyamu ndi mawaya amkuwa angagwiritsidwe ntchito polumikizana.
Kugwiritsa ntchito
YC9VA voliyumu ndi mawonekedwe apano omwe amagwiritsidwa ntchito poyang'anira, mafakitale ndi nyumba zogona ndipo ali ndi ntchito yoteteza mizere yagawo limodzi:
Chitetezo chochepa;
Kutetezedwa kwa overvoltage;
Kugwira ntchito pansi pa voltmeter mode.
Ntchito ndi Kuyika Ntchito
Mphamvu yamagetsi ikagwiritsidwa ntchito pa chipangizocho, chizindikiro cha digito chidzawonetsa mtengo wamakono wamagetsi pamaneti.
Kuwala konyezimira kukuwonetsa kuti palibe voteji pakutulutsa kwa chipangizocho.Ngati magetsi operekera ali mkati mwamtundu wokhazikitsidwa, pambuyo pa Ton (zosakhazikika ndi masekondi 30), katunduyo adzayatsa ndipo chizindikirocho chidzasiya kung'anima.Ngati magetsi sali mkati mwazomwe zafotokozedwa, katunduyo sungagwirizane ndi mzere mpaka magetsi abwerere mwakale.Pakadali pano, ngati voliyumu ndi yotsika kuposa malire omwe adayikidwa pakuyambiranso, chizindikiro cholakwa chidzawunikira.Ngati voteji ndi yapamwamba kuposa malire apamwamba, chizindikiro cholakwacho chidzakhalabe.
1. Kukhazikitsa ndi kuteteza relay.
2. Lumikizani mawaya ku relay malinga ndi dongosolo.
3. Khazikitsani mtengo wamagetsi womwe mukufuna.
4. Khazikitsani nthawi yoyenera kuyankha.
