Indlela ukudibanisa i RCD

Kutshanje, xa iifestile yeevenkile zombane, ungabona isixhobo ukwazi, zibonakaliswe yi-RCD ungayiqondiyo. Nangona ngenxa yomsebenzi wakhe akukho nto mbuso, nje ngoku kwafumaniseka ukuba kakhu- ethandwayo. Yinto elula: ukuba phambi kokuba avareji yokuhlala lombane ibandakanya ezimbalwa izibane ezingqengezelayo, intsimbi esezantsi-amandla kwisamkeli TV, ngoku uluhlu likhule kakhulu. Ngako oko, eli nani lenyuswa laya kunye nokwenzeka kho usiva ukuba abantu. Njengoko usazi, ukuziphendulela kakhulu kule meko kukuba yokufaka isekethe isiseko kunye nokufakelwa kwazo zonke izixhobo zombane kuyo. Nangona kunjalo, oku akusoloko kusenzeka. Ukongeza, kulula kakhulu ngocoselelo ecaleni imitha yombane ukudibanisa i RCD, kunokuba ukuzoba imigca ukusuka zonke izixhobo kumphathi wesekethe olukhuselayo.

akukho nzima

Umgaqo nokusebenza isixhobo yokhuseleko isekelwe uthelekisa amaxabiso Rule yale imisinga ezimbini - ayahamba na lesigaba kunye namasebe zero. Ngokwesiqhelo ke bayalingana (okanye delta ngaphakathi kuluhlu obuvumelekileyo), kodwa ke imbonakalo scheme umahluko iphathwa njenge kuvuza eyingozi, kwaye RCD icinyiwe. Ukuze uqonde ukuba yintoni na lo mzobo Uxhulumaniso RCD kunye oomatshini, kufuneka ukuqonda ngokucacileyo migqalisela ilapha ngentla. Ngoko ke, makhe usebenzise umzekeliso isingxobo kunye engamanzi. Vumela i inqaba abstract xinzelelo - yinto indlu bonke abathengi zombane. Kule zohlobo isusiwe - "igalelo" sonikezelo lwamanzi kunye "imveliso" some. Kucacile ukuba lo gama inqaba sivaleke vingci, inani ulwelo engenayo abuyele ngokulinganayo. Kodwa kamsinya nje amanzi yemveliso awekho - uyakwazi ukuthetha malunga ukuvuza. Kwaye ke umahluko inkulu anganalo babone ukuba mkhulu umonakalo lwenqaba loxinzelelo. Kulula ukuqonda ukuba ombane kufuneka ibe naphi na ukuba ashiye wesekethe. Ukuba oku kuyenzeka, ngoko ndaweni kukho ukuvuza, okanye, mhlawumbi, le nkqubo "imicu" sokubala. Ebona oku, uyakwazi ukufunda ngakumbi njengoko na ohlanganisa RCD.

Philosophy Electrical

Masithi kukho umonakalo ucingo ubushushu, kwaye isigaba (current) kwisekethe kumatshini wokuhlamba wabonakala phezu istili metal. Xa uthinte ntoni na ukuvuza ezikhoyo umzimba womntu, nto leyo eyingozi kakhulu. Ukuthintela oku, kufuneka ukudibanisa RCD. Kulo mzekelo, isixhobo mabarekhode umahluko imisinga engenayo nephumayo kwaye nangoko vala lulonke chain sonikezelo.

Ukuhlobanisa kwe RCD

Ukufakelwa kwesixhobo lulula yaye oko kubangela ubunzima nkqu kwezombane basandula kuqalisa ukuzisebenzisa. Kodwa ke, kufuneka kuqala ukhethe apho kuya kufakelwa i-RCD. Kukho ezintathu: ngqo kumgca unikezelo amandla isithuthi; kwi iqela isebe kwezixhobo; kuba yonke indlu. Indlela yokuqala luphawulwa lokhuseleko, kodwa oko kuthatha ixesha elininzi izixhobo zokhuselo. Okwesibini - vumelwano, kakuhle wesithathu kancinci iindleko, kodwa vakalelo luphantsi yokuvuza. RCDs zikhona naziphi na-output ezine ezinjengeetheminali: ezimbini ngezigaba unikezelo zero kunye output ezimbini. Ngakuye apho kusoloko ubhalo engqinelanayo, ngoko ukubaphazamisa into phantse ayinakwenzeka. Ngenxa yoko, isigaba lwenziwa kwi langutela kunye negama elifanayo - Imveliso esuka kwi RCD. Ukuze zero le meko efanayo. Nceda qaphela ukuba unako ukuvumela i "zero" yokucima i-RCD (khumbula umgaqo operation).

Indlela elula ku

Ngokomzekelo, cinga ngendlela elula. Kwaba kaninzi kusetyenziswa bakhe, qhagamshela RCD kweli lizwe. Uvakalelo kwefowuni for obandayo kwi ugwebu kufuneka abe phakathi kuka-100 ukuya 300 Ma (amaxabiso ezincinane ezi positives bobuxoki kunokwenzeka). Thelekisa: ukhuselo umatshini (umz, umatshini wokuhlamba) kufuneka RCD ne yangoku 10 MA; kunye nokhuselo lonke iqela - hayi ngaphantsi kwe-30 Ma. Ngoko ke, kungakhathaliseki nokuba kusetyenziswa kuphela RCD umehluko oluzenzekelayo (utshintsho, kudityaniswe isixhobo ukhuseleko), isigqibo isoloko enxulumene emva kokuba umatshini induction zaseprayimari. Kukho iingcingo ezimbini ukusuka iswitshi eziphezu igalelo RCD kunye neziphumo zayo - on. Ongaka ibandla osuka yenziwa kwiqela lenjongo counter.
