Thermal mifananidzo inzira iri nyore yekuona mutsauko wetembiricha muindasitiri yechitatu-chikamu magetsi maseketi, zvichienzaniswa neakajairika maitiro ekushanda.Nekuongorora kusiyana kwekupisa kwezvikamu zvese zvitatu padivi-ne-parutivi, nyanzvi dzinogona kukurumidza kuona kusawirirana kwekuita pamakumbo ega nekuda kwekusagadzikana kana kuwandisa.
Kusagadzikana kwemagetsi kunowanzo kukonzerwa nekusiyana kwezvikamu asi zvinogona kunge zvichikonzerwa nenyaya dzemidziyo senge yakakwira kuramba.Kusagadzikana kudiki kwemagetsi anopihwa kumota kunokonzeresa kusaenzana kwakakura kwazvino izvo zvinounza kuwedzera kupisa uye kuderedza torque nekushanda.Kusagadzikana kwakanyanya kunogona kuridza fuse kana kufambisa a breaker ichikonzera imwe nhanho uye matambudziko anosanganisirwa nawo senge mota kupisa uye kukuvara.
Mukuita, hazvigoneke kunyatso kuenzanisa ma voltages muzvikamu zvitatu.Kubatsira vashandisi vemidziyo kuona mazinga anogamuchirwa ekusagadzikana, iyo National Electrical
Manufacturers Association (NEMA) yakanyora zvakatemwa zvemidziyo yakasiyana.Aya mabhesi inzvimbo inobatsira yekuenzanisa panguva yekugadzirisa uye kugadzirisa matambudziko.
Chii chekutarisa?
Bata mifananidzo inopisa yeese mapaneru emagetsi uye mamwe marefu ekubatanidza mapoinzi akadai sedhiraivha, madhiraini, zvidzoreso uye zvichingodaro.Kwaunowana tembiricha yakakwira, tevera dunhu iro uye ongorora yakabatana matavi uye mitoro.
Tarisa mapaneru uye zvimwe zvinongedzo zvakavharwa nemavhavha.Sezvineiwo, iwe unofanirwa kutarisa zvishandiso zvemagetsi kana zvanyatsodziya uye pakadzikama mamiriro ane inokwana 40 muzana yemutoro wakajairika.Nenzira iyo, zviyero zvinogona kuongororwa zvakanaka uye zvichienzaniswa nemaitiro akajairika ekushanda.
Kutsvaga chii?
Mutoro wakaenzana unofanirwa kuenzana nematembiricha akaenzana.Mumamiriro ezvinhu asina kuenzana emutoro, chikamu (s) chakaremerwa chichaonekwa chichidziya kupfuura mamwe, nekuda kwekupisa kunokonzerwa nekupikisa.Zvisinei, mutoro usina kuenzana, kuwandisa, kushamwaridzana kwakaipa, uye nyaya ye harmonic zvose zvinogona kuumba muenzaniso wakafanana.Kuyera mutoro wemagetsi kunodiwa kuti uongorore dambudziko.
Seketi kana gumbo rinotonhorera-kupfuura zvakajairika rinogona kuratidza chikamu chakundikana.
Iyo inonzwika nzira yekugadzira nzira yenguva dzose yekuongorora iyo inosanganisira ese akakosha ekubatanidza magetsi.Uchishandisa software inouya neanopisa mufananidzo, chengetedza mufananidzo wega wega waunotora pakombuta uye tarisa zviyero zvako nekufamba kwenguva.Nenzira iyo, iwe uchava nemifananidzo yekutanga yekuenzanisa nemifananidzo inotevera.Iyi nzira ichakubatsira kuona kana nzvimbo inopisa kana inotonhorera haina kujairika.Kutevera chiito chekugadzirisa, mifananidzo mitsva ichakubatsira kuona kana kugadzirisa kwakabudirira.
Chii chinomiririra "yambiro tsvuku?"
Kugadzirisa kunofanirwa kutungamirwa nekuchengetedza kutanga-kureva, mamiriro emidziyo anoisa njodzi yekuchengetedza-inoteverwa nekutsoropodza kwemidziyo uye nekukura kwekukwira kwekushisa.NETA (InterNational Electrical
Testing Association) nhungamiro dzinoratidza kuti tembiricha idiki se1°C pamusoro peambient uye 1°C yakakwirira kudarika michina yakafanana ine kurodha zvakafanana inogona kuratidza kushomeka kunobvira kunoda kuti kuferefetwa.
Miyero yeNEMA (NEMA MG1-12.45) inonyevera pamusoro pekushandisa mota chero ipi zvayo pamagetsi asina kuenzana anodarika chikamu chimwe chete muzana.Zvakadaro, NEMA inokurudzira kuti mota dziregedzerwe kana dzichishanda zvakanyanya.Safe unbalance percentages anosiyana kune mamwe midziyo.
Kutadza kwemota chinhu chinowanzoitika chevoltage unbalance.Mutengo wese unosanganisa mutengo wemota, basa rinodiwa kushandura mota, mutengo wechigadzirwa wakaraswa nekuda kwekugadzirwa kusina kuenzana, mashandiro emutsara uye mari yakarasika panguva iyo tambo yadzikira.
Zviito zvekutevera
Kana mufananidzo wekupisa uchiratidza kondakita wese achidziya kupfuura zvimwe zvikamu mukati mechikamu chedunhu, conductor anogona kuderedzwa kana kuremerwa.Tarisa chiyero checonductor uye mutoro chaiwo kuti uone kuti ndeipi nyaya.Shandisa multimeter ine clamp accessory, clamp mita kana simba remhando analyzer kuti utarise yazvino chiyero uye kurodha pachikamu chimwe nechimwe.
Padivi remagetsi, tarisa kudzivirira uye switchgear yekudonha kwemagetsi.Kazhinji, mutsara wemagetsi unofanirwa kunge uri mukati me10% yezita rezita.Neutral to ground voltage inogona kuve chiratidzo chekuremedza system yako kana kuti ingave chiratidzo che harmonic ikozvino.Neutral to ground voltage yakakwira kudarika 3% yenominal voltage inofanira kutanga kuferefetwa.Uyezve funga kuti mitoro inoshanduka, uye chikamu chinogona kuerekana chadzikira zvakanyanya kana hombe-chikamu chimwe chete chikauya online.
Voltage inodonha pamafuse uye ma switch anogonawo kuratidza seasina kuenzana pamota uye kupisa kwakanyanya panzvimbo yedambudziko.Usati wafunga kuti chikonzero chawanikwa, tarisa kaviri nezvose zvinopisa mufananidzo uye multi-mita kana clamp mita zviyero zvazvino.Hapana mafeeder kana maseketi ebazi anofanirwa kutakurwa kusvika pakakwirira inobvumidzwa.
Circuit load equations inofanirawo kubvumira ma harmonics.Mhinduro yakajairika yekuremedza ndeyekugoverazve mitoro pakati pemaseketi, kana kutonga kana mitoro yauya panguva yekuita.
Uchishandisa software yakabatana, dambudziko rega rega rinofungidzirwa rakafumurwa neanopisa mufananidzo rinogona kunyorwa mumushumo unosanganisira mufananidzo wekupisa uye mufananidzo wedhijitari wemidziyo.Ndiyo nzira yakanakisa yekutaurirana matambudziko uye kupa zano rekugadzirisa.
