Ukusetyenziswa kohlolo lokuvuza kwimithombo yokwakheka komhlaba

Inkcazo: Sonke siyazi ukuba iibhodi zeebhilibhodi kwiibhasi zebhasi zigcwele iingcingo ezahlukeneyo. Ngenxa yomoya nelanga, nokungabikho kwesondlo, ezinye izibane azilayiti ngqo, kwaye ezinye zazo ziyavuza. Iintambo zombane zihlala zisetyenziselwa ngaphandle ixesha elide, indawo yokusebenza ilukhuni, kwaye inqanaba lokhuseleko kunye nemigangatho yokhuseleko eyamkelwe kuyilo okanye ulwakhiwo ayiphezulu kangako, isekethe yombane iyaguga kakhulu, ingasebenzi kwaye ukuvuza. Kwisistim yesiqithi esifana nesikhululo sebhasi enye okanye indawo yokugada ibhasi, ukuba inkqubo yonikezelo lwamandla ithatha ibhokisi yonikezelo lonikezelo lwamandla oluphakathi, kufanelekile ukufakela i-residual monitor yangoku kwibhokisi yolawulo ephambili ukujonga ukuvuza komntu ngamnye. isekethe ngexesha lokwenyani kunye nokuhanjiswa kwesekethe, uqwalaselo 30mA relay of residual current ngaphandle kokulibaziseka kwisenzo sangoku kunye okanye 30mA ukuvuza ukukhusela switsha ukukhusela.

Amagama angundoqo: indawo yomthombo; umthombo; umbane wobuqu; impazamo yomhlaba; ukukhuselwa kukothuka kombane

0 Imvelaphi yoshishino

Ngenjikalanga ye-26 kaMeyi, 2019, amantombazana amabini afunyanwa elele emanzini amileyo kwindlela ebukekayo kuluntu lwaseHushan Dijingwan, kwisitalato saseYuhang, eHangzhou, kwaye akazange aphinde avuke. Ngokweengxelo ezivela kwisitalato saseYuhang kunye namajelo eendaba, kugwetywa kwangaphambili ukuba le ntlekele inokubangelwa kukothuka kombane.

Esi ayisosihlandlo sokuqala ukwenzeka. Kwiminyaka yakutshanje, kuye kwakho iimeko ezininzi zokuba abantwana babanjwe ngumbane ekuhlaleni, ngakumbi kufutshane nequla lomthombo. Ngenjikalanga ye-9 ka-Agasti 2013, eKudi Pet Park eBeijing Chaoyang Park, izinja ezimbini ezifuywayo zafa ngenxa yokothuka kombane kumthombo apho izinja zazidada khona, kungekuphela nje ukuba umnini-zinja naye wabethwa ngumbane xa wayengena equleni. amanzi ukuze asindise inja yakhe, waza wafa ekugqibeleni. Ngalo lonke ixesha xa ezi zinto zibonakala, oko kuphawula umngxuma onzulu kwisazela soluntu.

Kweminye imithombo okanye imithombo yendalo engavumelekanga ukuba ingene ngexesha lokusetyenziswa, abantu bakhuselekile, kodwa kusekho imithombo yamanzi kunye nemithombo yomhlaba apho abantu banokungena khona, Inomngcipheko omkhulu wokothuka kombane xa isihlwele singena, ukukhubazeka komntu. umzimba uyancipha, kwaye i-impedance yendlela yoqhagamshelwano yehla ukuya kwixabiso elincinci., kwaye ngokuqhelekileyo, kukho abantwana abaninzi ngakumbi kwezi ndawo.

Ukuze kukhuselwe ubomi babantu, kwiSiqendu 4.6.5: 《Iinkcukacha jikelele yokwakha umbane nobukrelekrele》(idrafti yokwamkelwa), ichaze ngokucacileyo ukuba:

Xa isixhobo sangoku esishiyekileyo (RCD) sisetyenziswa njengomlinganiselo owongezelelweyo wokhuseleko wokhuseleko lombane, ezi mfuno zilandelayo ziyakufezekiswa:

1. Ixabiso lesenzo sangoku esilinganisiweyo akufanele sibe ngaphezu kwe-30mA;

2. Ezi sekethe zilandelayo ezingaphantsi kwe-32A kufuneka zixhotyiswe nge-residual current device (RCD);

2.1 Isekethe yesokethi yobonelelo ngombane kubasebenzi ngokubanzi;

2.2 Isixhobo sombane esihambayo ngaphakathi;

2.3 Izixhobo zombane ezingaphandle ezinokuphathwa ngabantu;

I-3 i-Residual current device (RCD) kufuneka isetyenziswe njengenye yamanyathelo okukhusela;

4 Xa usebenzisa i-residual current device (RCD), i-conductor earthing ekhuselayo (PE) kufuneka ifakwe.

Umgangatho wokushiyeka okusebenzayo ngoku kwi-GB/T22387-2016 ucacisa ngokucacileyo,

Intsalela yangoku esebenzayo isilayidi kufuneka ixhotyiswe njengendlela yokhuseleko kwizixhobo ezifakelwe emanzini, ezifana nezixhobo zombane kumadama okuqubha, imithombo, amagumbi okuhlambela nakwiibhafu.

2 Intshayelelo yemveliso

Uthotho lwe-ASJ olushiyekileyo olusebenza ngoku relays kunye neemonitha ezishiyekileyo zesekethe ezininzi zinokwenziwa zibe sisixhobo sangoku esishiyekileyo esine-low-voltage circuit breaker kunye ne-low-voltage contactor, elungele ubukhulu becala i-AC 50Hz, i-voltage ekalikelwe i-400V nangaphantsi kwe-TT kunye ne-TN. imigca yokuhambisa amandla enkqubo.Ingasetyenziselwa ukukhusela iisekethe zombane kwiimpazamo zomhlaba, ukuthintela ukonakala kwezixhobo kunye neengozi zomlilo zombane ngempazamo yemisinga, kwaye inokubonelela ngokhuseleko lonxibelelwano olungathanga ngqo kwiingozi zokothuka kombane.

ASJ60 series intsalela esweni ngoku

3 Intshayelelo yomsebenzi

Uluhlu lwe-ASJ10/20 olusele lusebenza ngoku relays lunemisebenzi elandelayo: Uhlobo lwe-A okanye i-AC-uhlobo lomlinganiselo oshiyekileyo wangoku, ngelixa i-alamu ye-residual current over-limit instruct, rated residual operating current can be set, limiting non-driving time. inokusetwa, iiseti ezimbini zeziphumo zokuhanjiswa, kunye ne-on-site, ekude "uvavanyo" kunye "nokusetha kwakhona" imisebenzi;

I-ASJ60 i-series ye-residual ye-monitor yangoku inemisebenzi elandelayo: i-16 i-residual monitoring yangoku, i-1 isilumkiso se-relay output, i-16 ye-alarm relay output, igalelo le-2 DI, umsebenzi wokuvala ngokuzenzekelayo, umsebenzi wonxibelelwano olude, ukuvula nokuvala umsebenzi.

4 Isalathiso sobugcisa

ASJ10/20 uthotho intsalela yangoku amanyathelo relay izikhombisi zobugcisa

Iimpawu zobuchwephesha be-ASJ60 uthotho olushiyekileyo esweni ngoku

5 Imiyalelo yokhetho

Kufuneka sinikele ingqalelo kuhlobo lwesixokelelwano se-low-voltage xa ​​i-relay esebenzayo eseleyo isetyenziswa.

Ezinye iintlobo ze-wiring eziseleyo kufuneka zitshintshwe zibe ziintlobo ezimbini ezingentla ukuthintela ukungahambi kakuhle okanye ukungaphumeleli kwe-outlet.

Ukukhethwa kwe-transformer yangoku eshiyekileyo kufuneka isekelwe kwi-rate yangoku yesekethe eyintloko njengesalathiso.

Enyanisweni, njengoko kubonisiwe kumzobo, i-transformer ifakwe kwisiphaluka esikhulu okanye kwisebe, kwaye ugwebe ukuba uqhube i-breaker circuit ngokulinganisa i-residual current.

6 Umqukumbelo

Kwiingozi zokothuka kombane zemithombo okanye imithombo yomhlaba, ezi ngxaki ziyingxaki yolawulo ubukhulu becala. Ukuba usebenza nzima kulawulo olufanelekileyo, lunokupheliswa ngokwenene. Ukuba umthombo we-landscape awunakuchukunyiswa ngabantu abaqhelekileyo, akuyi kubakho zingozi zombane. Imithombo eqhelekileyo nayo inokuxhotyiswa ngeecingo. Ukuba akukho cingo okanye ungangena kwindawo yomthombo nangaliphi na ixesha, kusekho ingozi yokhuseleko.

Kwiingxaki ezinjalo, inokulawulwa ubuchwepheshe . Iivolthi ezingama-24 okanye ii-volts ezili-12 zombane wokhuseleko kufuneka zisetyenziswe kwimithombo yembonakalo-mhlaba, izibane zembonakalo-mhlaba, izibane eziphantsi komhlaba, kunye neentambo zokukhanya kwiindawo zikawonke-wonke. Zonke izibane ziyacinywa emini kwaye zivulwa kuphela ebusuku, kusetyenziswa ulawulo lokuhanjiswa. Ngexesha elifanayo, kunyanzelekile ukufaka isixhobo sokukhusela ukuvuza ukunqumla amandla ngokuzenzekelayo kwimeko yongxamiseko.

Kwangaxeshanye, ukubeka iliso kufuneka kwenziwe kakuhle. Kwelinye icala, ukwenza umsebenzi olungileyo wolawulo oluqhelekileyo, kwaye kwelinye icala, iiyunithi ezifanelekileyo kufuneka ziqhube uhlolo kumaxesha ngamaxesha ukunqanda ukuguga komgca kunye nomonakalo.
