Kushandiswa kweakavhurika-mhando yazvino transformer ine switching value

Open-type current transformers for IoT zvishandiso. Iyi Internet yeZvinhu purojekiti inosuma mashandisirwo eakavhurika-mhando azvino anoshandura mumapurojekiti ekugadzirisa, basa rekuvhurika-mhando ikozvino transformers ine switch, uye zvakanakira zvichienzaniswa neyakajairwa yakavhurika-mhando transformers, yakasanganiswa nekuongorora nyaya yeinjiniya.

Neshanduko yemadhorobha uye ekumaruwa magetsi magidhi muindasitiri yemagetsi yenyika yangu uye nekuenderera mberi kwekuvandudzwa kweautomation yeakaderera-voltage magetsi ekugovera masisitimu., yakavhurika-mhando ikozvino transformers, sechinhu chakakosha chemagetsi mune yakaderera-voltage magetsi ekugovera masisitimu, kutamba basa rinowedzera kukosha mukushandurwa kwegridi remagetsi. Iri kuramba ichiva pachena kuti yakashandiswa zvikuru mukuyera, metering, relay protection, system monitoring, kuchengetedzwa kwepasi uye kwakasiyana siyana kwesimba system kuongororwa.

Zvisinei, pakuisa yakavhurika-mhando yakaderera-voltage transformers parizvino pamusika, zvisungo zvingasasungwa, zvichiita kuti simbi yesimbi isanyatsovharwa; Iyo yepamusoro uye yakaderera iron cores haina kuvharwa, inokanganisa kurongeka kwetransformer kana kusabuda ikozvino. Iyo yakavhurika-mhando yazvino transformer ine switching value inogona kunyatso dzosera mamiriro ari pamusoro kune chiridzwa kana kumashure, uye ine tarisiro yakakura yekushandisa mumapurojekiti ekutarisa magetsi.

Azvino transformer is a sensor inoshandiswa kuyera alternating current

2. Kushanda musimboti wezvino transformer

Nheyo yekushanda yekuvhurika yakaderera-voltage ikozvino transformer inoratidzwa muFigure 1.

Iyo yekutanga mhepo yekuvhurika ikozvino transformer yakabatana mumutsara mumutsara uri pasi pekuyedzwa. I1 ndiyo mutsara wazvino, ndizvo, iyo yekutanga ikozvino yezvino transformer, uye N1 ndiyo nhamba yekutanga kutendeuka kweshanduko yazvino. I2 ndiyo yechipiri ikozvino yezvino transformer, N2 ndiyo nhamba yekutendeuka kwechipiri kweshanduko yazvino, uye Z2e ndiyo impedance yemidziyo yechipiri yedunhu uye waya dzekubatanidza. Kana iyo yekutanga ikozvino inoyerera ichibva kuP1 terminal yeazvino transformer uye ichibuda kubva kuP2 terminal, apo yechipiri Z2e yakabatana, zvichibva pamusimboti we electromagnetic induction, iyo yechipiri mhepo yemhepo inoshandura ine ikozvino I2 inoyerera kubva kuS1, kuburikidza neZ2e kusvika kuS2, gadzira loop yakavharwa.

Kubva pane izvi, inogona kuwanikwa kuti ikozvino I1×N1=I2×N2 mune yakanaka mamiriro, saka I1/I2=N1/N2=K, uye K ndiyo chiyero chekushandura cheshanduko yezvino. Zvisinei, sezvo musimboti wesimbi weiyo yakavhurika-mhando yazvino transformer yakatemwa, kushanda kwesimbi yesimbi kuchave kwakanyanya, saka nzvimbo yemuchinjikwa-chikamu chesimbi yesimbi ye transformer inofanira kuwedzerwa, uye nhamba yeampere-inotendeuka inofanira kuwedzerwa, uye I1×N1=I2 ×N2≥100AN.

Pamusoro pe, nokuda kwekuchinja kukosha kwekushandura pane transformer, kana buckle ye transformer isina kuvharwa zvakanaka kana kuti casing yakatyoka nekuda kwekuchembera kwe transformer., bhatani rekuchinja rinobuda, iyo inowanzovharwa inowanzovhurika, kufambisa kwechiratidzo kunogumiswa, uye transformer haina chiratidzo chekubuda; Kana buckle ye transformer yakajairika, iyo switch state inowanzovharwa, uye transformer inoshanda zvakajairika.

3. Vhura mhando yezvino transformer

Yakavhurika-mhando yazvino ma transformer anonyanya kushandiswa mumadhorobha uye ekumaruwa magetsi ekugadzirisa mapurojekiti muindasitiri. Iyo inoratidzirwa nekuiswa nyore, hapana chikonzero chekubvisa yekutanga busbar, uye inogonawo kushandiswa nemagetsi. Zvisinei, the low-voltage open-type transformers parizvino ari pamusika ane zvinotevera zvakaipa:

(1) Iyo yakavhurika-mhando yazvino transformer pamusika inogona kunge isina kusungirirwa kana iyo iron core inogona kusavharwa panguva yekuiswa, uye panogona kunge paine njodzi yekuti transformer inodonha kana kubviswa panguva yekushanda;

(2) Kana iyo yakavhurika-mhando yazvino transformer yakavhurwa zvechisikigo kechipiri mushure mekuiswa, pachava nematambudziko akadai sekusina chiratidzo.

Tichitarisa pane izvo zvataurwa pamusoro apa, AKH-0.66/K-SW yakatevedzana ikozvino ma transformer anogona kugadzirisa matambudziko ari pamusoro. Iyi transformer ine chimiro chakanaka, nyore kuisa uye kugadzirisa. Sezvakaratidzwa muMufananidzo 2, iyo transformer ine zvinotevera zvakanakira:

Ikozvino Transformer Sensor Equipment - Kushandiswa kweakavhurika-mhando yazvino transformer ine switching value

(1) AKH-0.66/K-SW akatevedzana azvino ma transformer haadi kubviswa panguva yekuiswa, uye inogona kushandiswa live, uye inogona kuiswa zvakananga panzvimbo mushure mekuvhara, kuderedza mari yebasa;

(2) AKH-0.66/K-SW yakatevedzana ikozvino transformer, pane 4 tungamira waya mune ino module, waya mbiri dzinotumira chiratidzo chazvino, uye waya mbiri dzinotumira chiratidzo chekuchinja;

(3) ZveAKH-0.66/K-SW akatevedzana ano shandurudzo, kana buckle isina kuvharwa kana transformer iri kuchembera, goko ratsemuka, magoko epamusoro neazasi anosvetuka, musimboti wesimbi hauna kubatana zvakanaka, uye yakanamirwa mugoko rezasi retransformer. Bhatani rakasimudzwa rekuchinja richabuda kumusoro, switch yacho yadimburwa, uye kutapurirana kwechiratidzo chekuchinja kukosha kunogumiswa, iyo inoita basa mukukurudzira iyo yakavhurika-mhando yakaderera-voltage transformer kumira kushanda.

(4) ZveAKH-0.66/K-SW akatevedzana ano shandurudzo, makwati ekumusoro neepasi ane maburi ekuvharisa emutobvu, iyo inofanira kuiswa chisimbiso pakarepo mushure mekuiswa.

4. Parameter yekuenzanisa tafura

Kubuda kweAKH-0.66/K-SW yakatevedzana yemazuva ano anoshandura ane mabasa akadai seasina kujairika yekuvhura alarm uye kuzivisa kwesimba-pa uye kudzima zviitiko.. Kukurumidza kukura kweindasitiri.
