Qhov Scope ntawm daim ntawv thov ntawm xoom sequence tam sim no transformer
Jun 16, 2023| CXRD －LJ series xoom-sequence tam sim no transformer yog cable hom, txais ABS engineering yas plhaub, resin cam khwb cia rau hauv tag nrho kaw, zoo rwb thaiv tsev kev ua tau zoo, zoo nkauj tsos, siab rhiab heev, zoo linearity, txhim khu kev qha lag luam, yooj yim installation, thiab lwm yam. yog zoo heev Nyob rau hauv lub general xoom-sequence tam sim no transformer. Kev siv ntau yam, tsis tsuas yog haum rau kev tiv thaiv electromagnetic relay, tab sis kuj haum rau cov khoom siv hluav taws xob thiab microcomputer tiv thaiv. coil grounding) xaiv qhov tsim nyog xoom-sequence tam sim no transformer.
Zero-sequence tam sim no transformers yog siv nyob rau hauv ntau yam, tsis tsuas yog haum rau electromagnetic relay tiv thaiv, tab sis kuj rau hluav taws xob thiab microcomputer tiv thaiv pab kiag li lawm. Cov neeg siv tuaj yeem siv cov ntsiab lus nruab nrab zoo hauv av lossis nruab nrab taw tes tsis zoo hauv av raws li kev ua haujlwm ntawm qhov system. Xaiv qhov sib thooj zero-sequence tam sim no transformer.
Lub zero-sequence tam sim no transformer yog siv ua ke nrog lub relay tiv thaiv ntaus ntawv thiab lub teeb liab thaum lub hwj chim system generates xoom-sequence grounding tam sim no, thiaj li hais tias cov cuab yeej ua hauj lwm kom paub txog kev tiv thaiv los yog saib xyuas. DH-LJ series xoom-sequence tam sim no transformers yog cable-hom, nrog ABS engineering yas casing, resin cam khwb cia rau hauv tag nrho kaw, zoo rwb thaiv tsev kev ua tau zoo, thiab zoo nkauj tsos. Nws muaj cov yam ntxwv ntawm siab rhiab heev, zoo linearity, txhim khu kev qha lag luam thiab yooj yim installation. Qhov kev ua tau zoo ntawm transformer yog zoo dua li ntawm cov xoom-sequence tam sim no transformer, thiab nws yuav siv tau nyob rau hauv ib tug dav ntau yam. Nws tsis yog tsuas yog haum rau kev tiv thaiv electromagnetic relay, tab sis kuj rau hluav taws xob thiab microcomputer tiv thaiv cov cuab yeej. Cov neeg siv tuaj yeem ua tau zoo hauv qhov nruab nrab ntawm qhov nruab nrab lossis nruab nrab taw tes raws li kev ua haujlwm ntawm qhov system. Yog hais tias qhov taw tes tsis zoo hauv av, xaiv qhov sib thooj xoom-sequence tam sim no transformer. Lub hauv paus ntsiab lus: Lub hauv paus ntsiab lus ntawm xoom-sequence tiv thaiv tam sim no yog raws li Kirchhoff txoj cai tam sim no: cov lej algebraic ntawm cov txheej txheem tam sim no ntws mus rau hauv ib qho ntawm hauv Circuit Court yog sib npaug rau xoom. Thaum cov kab thiab cov khoom siv hluav taws xob zoo li qub, cov vector sum ntawm cov tam sim no ntawm txhua theem yog sib npaug rau xoom. Yog li ntawd, qhov thib ob sab winding ntawm xoom-sequence tam sim no transformer tsis muaj teeb liab tawm, thiab tus actuator tsis ua haujlwm. Thaum muaj teeb meem hauv av, qhov vector sum ntawm cov tam sim no ntawm txhua theem tsis yog xoom, qhov txhaum tam sim no ua rau cov hlau nplaum sib nqus tsim nyob rau hauv lub nplhaib hlau tub ntxhais ntawm xoom-sequence tam sim no transformer, thiab induced voltage nyob rau theem nrab ntawm lub xoom-sequence tam sim no transformer ua rau tus actuator ua thiab tsav Lub tripping ntaus ntawv hloov lub zog mov network kom ua tiav lub hom phiaj ntawm av txhaum kev tiv thaiv.
