Series YTJLW10-720 Voltage Transformers
Ukugxeka
Series YTJLW10-720 ulandelelwano isigaba, zero ulandelelwano voltage kunye transformer yangoku luhlobo lwe-AC transformer kunye neenkcukacha zobugcisa ezihambelana nezixhobo zokudityaniswa eziziiprayimari nezizisekondari zeGridi kaRhulumente kwaye ngokuhambelana ne-T / CES 018-2018 "I-Distribution Network 10kV kunye I-20kV AC Transformers Iimeko zobuGcisa ". I-Voltage, i-current and power transformers yakhiwe kwimveliso, enokuthi ihlanganiswe ngokuthe ngqo kunye ne-circuit breaker ukuze yenze i-intelligent vacuum circuit breaker.easy ukufaka, ukusetyenziswa kwamandla aphantsi, ukuchaneka okuphezulu kunye nokulinganisa okuzinzile.
■ I-capacitor eyintloko isebenzisa i-capacitance elinganayo ukuqokelela i-voltage, enozinzo oluhle lwexesha elide kunye namava okusebenza kwexesha elide kwiigridi zamandla.
■ Imveliso yokuchasana yangaphakathi incinci, enokuthi ivumelane neentambo ezahlukeneyo, yoyise impazamo ebangelwa iintambo, kwaye impazamo yokutshintshiselana kwentambo ingaphantsi kwe-0.1%.
■ utshintsho oluchanekileyo oluncinci oluchatshazelwa bubushushu be-ambient, kwaye utshintsho oluphezulu lwempazamo lungaphantsi kwe-0.5% kuluhlu olupheleleyo lobushushu obuyi -40 °C ~ 70 °C, oluhlangabezana ngokupheleleyo neemfuno zesalathiso sokwahluka kobushushu bomgangatho we-3-level. i-transformer ichaziwe.
■ ithatha ukuxhathisa amandla okuzinzile kakhulu kunye nokujika kombindi wamandla aphantsi, uzinzo oluhle lwemveliso kunye nokuchaneka okuphezulu, kwaye ihlangabezana neemeko zokusebenza kwazo zonke iimeko zokusebenza.

Imilinganiselo kwiimilimitha
Indlela yokufakela
Imiyalelo yokufakela kunye nezilumkiso
■ Qinisekisa uqhagamshelwano oluthembekileyo phakathi kocingo lokumisa kunye nendlu ngexesha lofakelo.
■ Isiginali yemveliso yesibini ekhokelela kwi-transformer kufuneka ifakwe ngokusondeleyo kwibhokisi, kwaye iintambo ezingaphezulu kufuneka zinqunyulwe.
■ Ukukhutshwa kwamandla ombane wesibini we-transformer emhlabeni akuvumelekanga ukusebenza ngamaxesha ombane
■ Imiyalelo yocingo lwesibini
| UHLOBO | Ireyishini yotshintsho | Ukuchongwa kwendawo | phawula |
| Ulandelelwano lwesigaba sangoku | 600A/1V | Ia+Ia-,Ib+Ib-,Ic+Ic- | |
| Ulandelelwano lwangoku lwe-zero | 20A/0.2V | I0+ I0- | Identity I0+ I0- njenge Connect iintambo zotshintsho |
| Ukulandelelana kwesigaba sombane | 10kV/√3/3.25V/√3 | Ua+Ua-Ub+Ub-Uc+Uc- | |
| Voltage zero ulandelelwano | 10kV/√3/6.5V/3 | U0+ U0- | Isazisi U0+ njenge Connect iintambo zotshintsho |
Ekubeni i-voltage ye-zero-sequence current kunye ne-zero-sequence voltage idinga i-synthesis yesigaba sesithathu, kukho imfuneko yokudibanisa umgca wenguqu ephakathi, isigaba ngasinye I0 +, i-I0- ihambelana nokuxhuma;I-U0 + yesigaba ngasinye ihambelana nokukhwelana.Ngaphambi kokuba ushiye umzi-mveliso, imveliso ivaliwe,Nceda uyiphawule xa uyifaka.Ngokulandelayo:
