Disconnector switch (los yog Switch- Disconnector los yog Off-load Switch) yog ib qho khoom siv disconnecting uas tsis tuaj yeem hloov tawm tam sim no, yog li nws feem ntau cuam tshuam nrog lub Circuit Court breaker los yog ib qho kev hloov ntawm load. Circuit Court breaker yog ib qho khoom siv hloov pauv uas tuaj yeem txiav cov ntsuas tam sim no (Ir) thiab luv luv Circuit Court tam sim no (Ik).
Tsis tas li lo lus nug yog, qhov txawv ntawm qhov hloov pauv thiab cais tawm yog dab tsi?
Isolator thiab Disconnector yog ua manually. Circuit Breaker yog ib qho khoom siv hluav taws xob lossis hluav taws xob thiab cov khoom siv hluav taws xob. Isolator yog Mechanical Device ua raws li Hloov thiab muab cov haujlwm cais tawm. Isolator yog OFF-Load Device i.e. Disconnector tuaj yeem ua haujlwm thaum lub hwj chim mov tag nrho.
Ib sab saum toj, dab tsi yog qhov haujlwm ntawm disconnector? Hauv hluav taws xob engineering, a disconnector , disconnect hloov los yog rho tawm hloov pauv yog siv los xyuas kom meej tias cov hluav taws xob hluav taws xob tau ua kom tsis muaj zog rau kev pabcuam lossis kev saib xyuas.
Tsis tas li ntawd, qhov txawv ntawm lub breaker thiab disconnect yog dab tsi?
Ib fused txiav tawm switch yog kev sib txuas ntawm qhov hloov mus rau txiav tawm lub Circuit Court thiab lub fuse los kaw lub Circuit Court tawm hauv xwm txheej ntawm qhov teeb meem. Ib Circuit breaker combines lub zog ntawm kev hloov thiab ib qho overcurrent txiav tawm nyob rau hauv ib qho khoom siv.
Dab tsi yog fuse hloov disconnector?
Fuse - hloov disconnectors yog cov khoom siv hluav taws xob qis qis uas ua rau muaj kev nyab xeeb ntawm phau ntawv txuas thiab txiav cov hluav taws xob hluav taws xob nyob rau hauv kev thauj khoom, nyob ntawm qhov voltage thiab kev siv qeb. Nws tuaj yeem siv nrog kev txiav riam thiab tom qab ntawd muaj kev ua haujlwm ntawm hloov - disconnector.

Qhov sib txawv hauv zos tau tshaj tawm hauv ib qho kev ua haujlwm whereas Ntiaj teb hloov pauv tau tshaj tawm sab nraum lub luag haujlwm. Cov kev hloov hauv zos tau tsim thaum lub luag haujlwm tau pib ua tiav thiab ploj thaum lub luag haujlwm xaus, ntawm qhov tod tes, Ntiaj teb hloov pauv yog tsim raws li kev tua pib thiab ploj thaum qhov kev pab cuam xaus
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog qhov sib txawv Circuit Court?
Nyob rau hauv electronics, ib tug txawv yog acircuit uas yog tsim xws li hais tias cov zis ntawm lub circuit yog kwv yees li ncaj proportional rau tus nqi ntawm kev hloov (lub sij hawm derivative) ntawm cov tswv yim.
