Ingcaciso yeMveliso

I-JLS-35 uhlobo oludityanisiweyo lwe-transformer (isigaba sesithathu sebhokisi yokulinganisa i-oyile yangaphandle entywiliselwe kwi-high-voltage power metering) yenziwe ngamacandelo amabini ombane kunye neziguquli ezimbini zangoku (ekubhekiselwa kuzo njengeziqalelo ezibini), luhlobo lwangaphandle oluntywiliselwa ngeoli (elingakwazi isetyenziselwe Indoor), ikakhulu i-35kV, i-50Hz igridi yamandla yokulinganisa amandla ombane aphezulu.Ifakwe kwicala eliphezulu le-voltage ye-transformer yamandla ombane.Kukho iimitha ezimbini ezisebenzayo ze-watt-yure esebenzayo kunye neemitha ezimbini ezisebenzayo ze-watt-yure kwibhokisi yesixhobo.Zisetyenziselwa ukulinganisa ngokuthe ngqo imigca ye-high-voltage, kungakhathaliseki ukuba amandla athunyelwa okanye abuyiselwe.Izixhobo zokulinganisa umlinganiselo wamandla asebenzayo kunye nasebenzayo ekuhlaleni.Idlala indima ebalulekileyo ekuthinteleni ukubiwa kombane, ukonga amandla nokomeleza ulawulo lonikezelo lombane.
Ukuze uhlangabezane neemfuno eziguqukayo zomthwalo wamandla ngamaxesha ahlukeneyo, imveliso inokwenziwa ibe yi-double current ratio yokhetho lohlengahlengiso.Ukuba ibhokisi yemitha yeendlela ezimbini isetyenzisiwe, ingasetyenziselwa ukulinganisa inethiwekhi (oko kukuthi, ukulinganisa ubungakanani bombane owenziwe kwaye usetyenziswe ngokwahlukileyo).Le mveliso ineempawu zokuchaneka okuphezulu, ubungakanani obuncinci, i-insulation ethembekileyo, ukusebenza kakuhle kokutshatyalaliswa kobushushu, ukusebenza okukhuselekileyo kunye nokuzinza, kunye ne-wiring elula kwaye elula.Ngokweemfuno ezahlukeneyo zabasebenzisi, iimveliso zineentlobo ezahlukeneyo, ezinokudityaniswa ngokungqongqo kwaye zikhethwe ngokukhululekileyo.Sisixhobo esifanelekileyo solawulo lwangoku lwamandla.

Inkcazo yoMfanekiso

Iiparamitha zobugcisa kunye nemilinganiselo yesakhiwo

Iiparamitha eziphambili zobugcisa
1. Umlinganiselo oqhelekileyo: 50Hz
2. Ukuxhatshazwa kwe-insulation: eyona nto iphambili ukuya kweyesibini kunye neprayimari ukuya kumhlaba≥1000MΩ;okwesibini ukuya kweyesibini kunye nesekondari ukuya kumhlaba≥50MΩ
3. I-Thermal stable current ye-1 yesibini: amaxesha angama-75 alinganiswe ngokuphambili (ixabiso elisebenzayo)
4. I-Dynamic stable current: amaxesha angama-188 i-primary current (ixabiso lencopho)
5. Jonga le theyibhile ingezantsi kwezinye iiparamitha
Iimpawu zobugcisa

11. Indawo esetyenziswayo: ngaphandle, indawo yofakelo ayinangcoliseko enzulu, akukho ngcangcazelo lumbi kunye neendawo ezinamaqhuma.

Iimpawu zemveliso kunye nobungakanani bokusetyenziswa

Le mveliso iqulethwe ngamacandelo amathathu-amacandelo amabini adibeneyo i-transformer kunye nebhokisi yesixhobo.I-transformer yesigaba sesithathu sezinto ezimbini ezidibeneyo zenziwe nge-voltage yesigaba esisodwa (PT) kunye neenguqu ezimbini zangoku (CT).I-PT kunye ne-CT zimbini uhlobo lwe-Electromagnetic, i-PT windings ezimbini ze-PT zenziwe ngendlela yokudibanisa i-V / V, isixhobo sokulinganisa isigaba sesithathu, kunye ne-primary windings ye-CTs ezimbini zidibaniswe ngokulandelelana kunye nesigaba A kunye nesigaba C segridi ngokulandelanayo.Kwinxalenye yokulinganisa, kukho iimitha zamandla ezithathu ezisebenzayo kunye ne-reactive energy nganye ene-inverter ukuqonda umlinganiselo wamandla ombane wokugqithiswa kwamandla phambili kunye nokuhanjiswa kwamandla.
Xa sele iqhagamshelwe kwi-AP1-AP2, i-CP1-CP2 ngumlinganiselo omkhulu wangoku, kwaye xa uqhagamshelwe kwi-AP1-AP3, i-CP1-CP3 yincinci yangoku.
Umzekelo: 50-100/5, xa sele iqhagamshelwe kwi-AP1-AP2, i-CP1-CP2 yi-100/5, xa iqhagamshelwe kwi-AP1-AP3, i-CP1-CP3 yi-50/5.
Imveliso ine: ukuxinwa kwamagnetic okuphantsi, umthwalo obanzi, ibhokisi yokulinganisa umbane ochasene nobusela kunye nemilinganiselo emininzi yangoku, kwimeko yokuhanjiswa kwamandla e-bidirectional, kungakhathaliseki ukuba ixesha lomthwalo litshintsha kakhulu, ukuchaneka okuphezulu kwe-0.2S kunokulinganisa ngokuchanekileyo amandla ombane. kwaye nangokunjalo.
