Kunoza Umutekano no Gukora neza hamwe na JCH2-125 Main Switch Isolator

Amashanyarazi agira uruhare runini mubuzima bwacu bwa buri munsi, ariko birashobora no guteza akaga iyo bidacunzwe neza. Kugirango sisitemu y'amashanyarazi ibungabunge umutekano, ni ngombwa kugira ibintu byizewe, bikora neza. Bumwe muri ubwo buryo niJCH2-125Inzira nyamukuru. Muri iyi blog, tuzasesengura ibiranga ibicuruzwa nibyiza, twibanda kuburyo biteza imbere umutekano nubushobozi bwa porogaramu zitandukanye.

Biratandukanye kandi byizewe:
UwitekaJCH2-125imiyoboro nyamukuru ihindura iraboneka muri 1-pole, 2-pole, 3-pole na 4-pole iboneza kugirango byuzuze ibisabwa bitandukanye. Ubu buryo butandukanye butuma habaho guhinduka mugushushanya no gushiraho sisitemu y'amashanyarazi, ikemeza guhuza nibikorwa bitandukanye. Ikigereranyo cyayo cya 50 / 60Hz itanga imikorere myiza kandi irakwiriye kubidukikije ndetse nubucuruzi.

Ihangane na voltage nubu:
Ubushobozi bwo guhangana na voltage nubushyuhe bugezweho nibyingenzi kuri sisitemu y'amashanyarazi. Impulse yagereranijwe kwihanganira voltage ya JCH2-125 nyamukuru ihinduranya ni 4000V, irashobora gutanga uburinzi buhagije bwo kwiyongera gutunguranye. Byongeye kandi, igipimo cyacyo kigufi cyumuzingi cyihanganira amashanyarazi (lcw) ya 12le kuri t = 0.1s itanga imikorere yizewe nubwo haba mubihe bikomeye.

Gukora no kumena ubushobozi:
Gukora ni urufunguzo muri sisitemu y'amashanyarazi, kandi JCH2-125 nyamukuru ihinduranya ikemura ibyo ikeneye hamwe nubushobozi bwayo bwo gukora no kumena. Ifite ubushobozi bwo gukora no kumena ubushobozi bwa 3le, 1.05Ue, COSØ = 0,65 kugirango igenzure neza kandi neza. Iyi mikorere itanga imbaraga nke mugihe cyo gukora, igira uruhare mubikorwa byingufu no kuzigama amafaranga.

Icyerekezo cyiza cyo kwerekana:
Umutekano ningenzi mugihe ukorana namashanyarazi, kandi JCH2-125 izigunga ibishyira imbere hamwe nibyiza byayo byerekana. Igikoresho cya isolator gifite icyatsi / umutuku utanga ibimenyetso bifatika byerekana uko amashanyarazi ahagaze. Icyatsi kibisi kigaragara cyerekana icyuho cya 4mm, wizeza uyikoresha ko switch ifunze kandi umuzenguruko uri wenyine. Iyi mikorere igabanya ibyago byo guhitanwa n amashanyarazi bitunguranye, bityo umutekano ukiyongera.

Urwego rwa IP20 rwo kurinda:
JCH2-125 nyamukuru ihinduranya yateguwe hamwe nurwego rwo kurinda IP20, rushobora gutanga uburinzi bwizewe kubintu bikomeye bifite diameter irenze 12mm. Iyi mikorere yemeza ko ibicuruzwa biramba ndetse no mubidukikije bikaze, bigatuma bikenerwa mubikorwa bitandukanye byinganda nubucuruzi. Igipimo cya IP20 kandi kirinda umukungugu nibindi bice kwinjira muri switch, bikarushaho kongera ubwizerwe no kuramba.

mu gusoza:
Muncamake, JCH2-125 nyamukuru ihindura itanga itanga urutonde rwuzuye rwibanze rushyira imbere umutekano wamashanyarazi no gukora neza. Hamwe nimiterere yayo itandukanye, ubushobozi bwo guhangana na voltage nubushyuhe bugezweho, gukora neza no kumena ubushobozi, kwerekana imikoranire myiza hamwe no kurinda IP20, iyi switch ni amahitamo yizewe kubikorwa bitandukanye. Gushora imari muri JCH2-125 nyamukuru itandukanya ibintu ntabwo bizarinda umutekano wa sisitemu y'amashanyarazi gusa, ahubwo bizanagira uruhare mukugenzura neza amashanyarazi no kuzigama igihe kirekire.
