Munhu wese anogona kunge achinyatsoziva nezvemamita emagetsi. Mazuva ano, mamita akangwara anowanzo shandiswa kuyera nekubhadharisa magetsi emumba. Kana ukanyatso tarisa, uchaona kuti pane parameter 5 (60) yakanyorwa panzvimbo yaionekwa yemita yemagetsi.

Semuenzaniso, paramita iri mudenderedzwa dzvuku mumufananidzo uri pamusoro: 5 (60) A. Tichitarisa yuniti, tinoziva kuti yakanyorwa se current, saka hukama huripo pakati pe currents mbiri idzi ndehwei? Chii chinoitika kana current yadarika? Ngatitaurei nezvezvinorehwa ne currents mbiri zvichienderana nema brackets ekunze (5) uye mukati mema brackets (60).
Magadzirirwo emagetsi ari mumabhuraketi
Mwenje uri mumabhureki - 60A mumuenzaniso, unoreva mwenje wepamusoro wakayerwa wemita yesimba. Kusiyana nemimwe michina, mwenje wemagetsi wakayerwa wemita yesimba remagetsi unokanganiswa zvakanyanya nezvinhu zvezvakatipoteredza, saka muganho wakati unosara paunobuda mufekitori - mwenje wepamusoro wakayerwa i120% yemagetsi akanyorwa. Naizvozvo, kana nhamba iri mumabhureki iri 60, mwenje wayo wepamusoro wakayerwa i72A - kana isiri nzvimbo yakaoma zvakanyanya, kukanganisa kwemwenje wepamusoro wakayerwa kazhinji hakuzosviki 20%. Saka, mwenje wepamusoro wakayerwa wemita wakanyorwa ne60A kazhinji ungangoita 66A mukushandiswa chaiko.
Chii chinoitika kana kukosha uku kwapfuura? Mhinduro yacho ndeyekuyera kusina kururama - pamwe kwakawanda, pamwe kwakaderera.
Mabhureki ekunze aripo iye zvino
5 iri kunze kwemabhuraketi pano inonzi basic current, inonziwo calibration current. Inotsanangurwa ne starting current ye electric energy meter - iyo minimum current value inobvumira electric meter kuti irambe ichitenderera uye ichiyera nguva dzose. Starting current ye general smart meter i0.4% ye rated current. Kureva kuti, meter ine rated current ye 5A ichachajwa chero bedzi current iri mu circuit yasvika 0.02A kana ichishandiswa. Pachava ne ratio pakati pe rated current ne rated current yepamusoro, senge 5 (60) A, inova hukama hwe 4 times. Iyi ratio inonzi "load width". Kazhinji, kune 2 times, 4 times, 6 times, 8 times kana kutopfuura gumi times - load width yakakura, technical level inodiwa yakasimba, uye mutengo we meter uchava wakakwira.
Saka, nhamba dziri kunze kwemabhureki hadzina chekuita nekushandiswa chaiko nemushandisi—zvishoma kana zvishoma pane izvi hazvizokanganisi kuyera kwemita. Pane zvinhu zviviri zvinokanganiswa nekuyera kwemita: mutengo wemita (une chekuita nehupamhi hwemutoro) uye kutanga kwesimba (kunoverengwa nekuyera kwesimba).
