Hloov pauv zaus tsav tshuab txuag lub zog. Tab sis lawv kuj tsim ob qho teeb meem. High harmonics thiab ntau hom voltage. Cov kab hluav taws xob zoo tib yam tsis tuaj yeem cuam tshuam qhov cuam tshuam no. Qhov no ua rau kev puas tsuaj thaum ntxov ntawm lub cev muaj zog. Bearings tau puas los ntawm hluav taws xob yaig. Cov cuab yeej ze ze muab cov cim cuav.
Peb Vfd Motor Cable yog VFD cable. Cia kuv rov hais dua. Peb Vfd Tsav Cable yog VFD tshwj xeeb sib txuas tiv thaiv cable. Nws qhov ntsuas hluav taws xob yog 0.6 / 1kV. Nws yog tsim los txuas VFD rau VFD lub cev muaj zog. Nws txo cov hluav taws xob hluav taws xob zoo. Nws kuj txo cov peev txheej hauv av.
Peb siv 3+3 core kev npaj. Qhov ntawd txhais tau hais tias peb lub ntsiab cores thiab peb qhov nruab nrab cores sib npaug thiab sib npaug. Cov qauv no ua tau zoo tshem tawm xoom kab ke harmonic flux. Nws tiv thaiv nruab nrab taw tes drift.
Lub shielding txheej yog cov qauv sib xyaw. Sab nraum cov tub ntxhais hlua khi hlua, peb ua ntej ua tooj liab hlau winding shielding. Kev pab them nqi yog 90% lossis ntau dua. Tom qab ntawd peb qhwv cov ntaub nplaum mos. Kev sib tshooj yog 15% lossis ntau dua. Cov tooj liab hlau winding muab DC tsis tshua muaj kev tiv thaiv hauv av. Daim kab xev tooj liab muab 100% high zaus hluav taws xob tiv thaiv kev tiv thaiv.
Cov rwb thaiv tsev yog XLPE. Qhov ntsuas kub yog 90 degree. Nws tuaj yeem tswj cov kab hluav taws xob siab los ntawm VFD cov zis. Lub plhaub yog nplaim retardant PVC.
Cov tooj liab hlau ntxiv rau tooj liab daim kab xev sib xyaw ua ke muab cov cable hloov impedance tsawg li 50mΩ / m ntawm 30MHz. Qhov no txhais tau hais tias lub siab zaus hom tam sim no los ntawm VFD yog sai sai absorbed los ntawm shielding txheej. Ces nws mus rau hauv av. Radiation rau sab nraud yog txo qis heev.
Lub symmetrical 3+3 qauv thiab qis impedance shielding txheej zoo sib npaug ntawm peb theem voltage. Nws txo qhov voltage hom ntawm lub cev muaj zog bearing kom tsawg tshaj li ib feem tsib ntawm ib tug unshielded cable. Lub cev muaj zog bearing lub neej yog txuas ntxiv.
Tus neeg xyuas pib ua haujlwm kub yog 90 degree. Qhov tsawg kawg nkaus khoov vojvoog yog 15 npaug ntawm cov kab hluav taws xob sab nraud. VFD cables muaj qhov nruj dua qhov yuav tsum tau khoov vojvoog vim tias lawv cov qauv nyuaj.
Lub shielding txheej yuav tsum muaj kev ntseeg siab hauv av ntawm ob qho kawg. Qhov no ua kom muaj kev cuam tshuam ntau zaus tam sim no muaj txoj hauv kev luv tshaj plaws. Yog hais tias grounded ntawm ib kawg, qhov siab zaus impedance nce sharply. Cov nyhuv shielding ploj lawm.
Cov khoom lag luam tus qauv coj lub sijhawm nyob ntawm seb muaj pes tsawg. Peb sim peb qhov zoo tshaj plaws kom tau raws li cov neeg siv khoom xav tau. Tib yam mus rau cov khoom siv. Lub hli ntau lawm muaj peev xwm nyob ntawm cov specifications. Cov qauv sib txawv muaj cov zis sib txawv.
