Mamiriro uye Phenomenon yeEnergy Meter's No-load Behaviour
Kana iyo mita yemagetsi isina-mutoro maitiro mukushanda, mamiriro maviri anofanirwa kugutsikana.(1) Panofanira kunge pasina ikozvino mudunhu razvino remamita emagetsi;(2) mita yemagetsi haifanirwe kuburitsa anopfuura rimwe pulse.
Iyo isina-mutoro maitiro emamita emagetsi anogona chete kutsanangurwa kana zviri pamusoro apa mamiriro akasangana panguva imwe chete.Kana iyo isina-mutoro maitiro inokonzerwa kupfuura 115% yereferensi voltage, maererano nemitemo yakakodzera, mita yemagetsi inokodzera, iyo yaisagona kuonekwa seisina-mutoro maitiro;asi kana zvasvika kune vashandisi, sekudzoserwa kwemagetsi kune chekuita, zviri pachena kuti inofanirwa kutorwa senge isina-mutoro maitiro panzvimbo peyakajairika.
Kuti uite mutongo chaiwo, kuongororwa kunoitwa zvinoenderana nemamiriro ari pamusoro apa:
I. Iko hakuna ikozvino munharaunda yemazuva ano yemamita emagetsi
Chokutanga pane zvose, mushandisi haashandisi chiedza, mafeni, TV uye zvimwe midziyo yemumba, izvo hazvirevi kuti hapana ikozvino munharaunda yemazuva ano yemamita emagetsi.Zvikonzero zvinotevera:
1. Internal leakage
Nekuda kwekusagadzirisika, kukuvadzwa kwekudzivirira kwewaya dzemukati uye zvimwe zvikonzero, kubatana kwemagetsi kunoitika pasi uye kubuda kwemvura kunogona kuita kuti mita ishande panguva yekuvhara.Mamiriro ezvinhu aya haakwane nechimiro (1), saka haafanire kutorwa seasina-mutoro maitiro.
2. Tora iyo sub-energy mita yakabatana kune main mita semuenzaniso.Sirin'i fan isina blade inobatidzwa zvisirizvo munguva yechando.Kunyangwe pasina kujeka kushandiswa kwemagetsi pasina ruzha uye chiedza, mita yemagetsi yanga ichishanda nemutoro, uye zvechokwadi haigone kutorwa senge isina-mutoro maitiro.
Naizvozvo, kuti uone kana iyo magetsi emagetsi mita pachayo isingashande hapana-mutoro unoshanda, iyo huru switch pamagetsi emagetsi meta terminal inofanira kubviswa, uye mutsara wechikamu kumucheto wepamusoro weiyo switch unofanirwa kubviswa mune dzimwe nguva. .
II.Iyo mita yemagetsi haifanirwe kuburitsa zvinopfuura imwe pulse
Mushure mekuita chokwadi chekuti hapana ikozvino munharaunda yemazuva ano yemamita emagetsi, inogona kutariswa kana isiri-mutoro maitiro kana kwete zvichienderana nekuti chiedza chepulse chinopenya kana kwete.Muyedzo wekubuda kwemamita haufanire kunge uine pulse inodarika imwechete.
Mushure mekusimbisa maitiro asina-mutoro, nyora pasi nguva t (miniti) yepuru yega yega uye inogara c (r/kWh) yemamita emagetsi, uye dzosera mutero wemagetsi zvinoenderana neinotevera fomula:
Magetsi akadzorerwa: △A=(24-T) ×60×D/Ct
Muchidimbu, T inoreva zuva rega rega rekushandisa magetsi nguva;
D zvinoreva nhamba yemazuva emamita emagetsi hapana-mutoro maitiro.
III.Dzimwe nyaya dzemagetsi mita's no-load maitiro:
1. Ikozvino coil ipfupi-inotenderera nekuda kwekuremerwa uye zvimwe zvikonzero, uye iyo voltage inoshanda magineti inobatwa neizvi, iyo inotsemuka kuita zvikamu zviviri zvekuyerera munzvimbo dzakasiyana uye nguva dzakasiyana, zvichikonzera kusashanda-mutoro.
2. Iyo yechitatu-phase inoshanda watt-awa mita haina kuisirwa maererano neyakatsanangurwa chikamu kutevedzana.Kazhinji, iyo nhatu-phase mita inofanirwa kuiswa zvinoenderana nechakanaka chikamu chinoteedzana kana inodiwa chikamu chinoteedzana.Kana iyo chaiyo yekumisikidza ikasaitwa zvinoenderana nezvinodiwa, mamwe mamita emagetsi akapindirana zvakakomba neiyo electromagnetic dzimwe nguva ichaita isina-mutoro maitiro, asi inogona kubviswa mushure mekugadzirisa kutevedzana kwechikamu.
Muchidimbu, kana hunhu husina-mutoro huchiitika, hazvifanirwe chete kutarisa mamiriro emamita emagetsi pachawo, asi zvakare dzimwe nguva tarisa wiring uye mamwe madhizaini emagetsi.
