Gukoresha ibikoresho by'amashanyarazi bitunganijwe neza cyangwa bishaje mubihe byangiza bishobora kwerekana abakozi nabashyitsi ibyago byo guhitanwa n amashanyarazi, cyane cyane iyo bahuye nubutaka.
Wishingikirize kuri RCDs kugirango wongere ukingire amakosa.Ibikoresho byinshi bihari byashyizwe ahubatswe mubwongereza birimo AC RCDs.
AC RCDs ntabwo ikwiriye gukoreshwa hamwe nibikoresho byinshi bigezweho byamashanyarazi nibikoresho bikoreshwa ahubatswe, usibye guhangana nubushyuhe bwo gushyushya no gucana - reba BS7671 Ivugurura 2.
Ibisabwa muri rusange kuri ubu buryo bitangwa mugice cyingenzi cyibikorwa byikora byikora.Ivugurura rya 2 rirangiye § 531.3.3 rigira riti: “Ubwoko bwa AC RCD * buzakoreshwa gusa mu bikorwa mu bikoresho byagenwe bifite imizigo izwi idafite ibintu bigize DC.”
Gukwirakwiza no kugenzura ibikoresho bifitanye isano no gutanga amashanyarazi, cyane cyane ibikoresho byacometse, nikibazo gikomeye cyubuzima n’umutekano.Ingaruka zijyanye no guhuza ibikoresho byibyiciro bitatu nisoko yingufu zisanzwe zirinzwe nubwoko butari bwo bwa RCD nibishobora guteza akaga ahantu hose mubwongereza.Ibi biramenyekana kandi byemewe muri HD 60364-7-704 2018 Umugereka wa ZB: Kubidage byubatswe n’isenywa ry’Abadage / Socket zose uko ari 3 eshatu zigera kuri 63 A zigomba kurindwa nubwoko B RCDS.
Kwishyiriraho by'agateganyo: Ibikoresho byose byafunzwe bikimurirwa ahantu hashya cyangwa byoherejwe gusana / gusana bizubahiriza ibisabwa byumutekano bigezweho, ni ukuvuga ko byashyizwe mubikorwa bishya kandi byujuje ibisabwa nubuyobozi.
Guhuza ibikoresho bishya: Amabwiriza yubuzima n’umutekano (reba hano hepfo) ashimangira ko hakenewe abakozi babishoboye kugirango barebe ko ibikoresho bitanga amashanyarazi n’ibirinda bikwiranye n’ibikoresho bihujwe, urugero, ubwoko bwa RCD bugomba kuba bukwiye ku bikoresho bifitanye isano / igikoresho.- reba BS 7671 531.3.3
* Ibisobanuro byemewe n'amategeko: "Shall" bivuze ko umuntu afite inshingano cyangwa inshingano zo gukora igikorwa.
Ubuyobozi butangwa mu gitabo cy’ubuyobozi bwa HSE na BS7671 bushigikira kubahiriza ibisabwa n’amategeko agenga ubuzima n’umutekano mu Bwongereza.
RCDs zatoranijwe neza zitanga uburinzi hamwe nuburinzi bwinyongera - reba Ibisabwa Gusuzuma Ibyago: Igitabo cya HSE Gukora ku bikoresho byamashanyarazi. Ubuyobozi (Indent 4 & 5) buvuga ko mbere yo guhuza ibikoresho, "umuntu ubishoboye" agomba kugenzura ibicuruzwa. Ubuyobozi (Indent 4 & 5) buvuga ko mbere yo guhuza ibikoresho, "umuntu ubishoboye" agomba kugenzura ibicuruzwa.Igitabo (paragarafu ya 4 n'iya 5) kivuga ko "umuntu ubishoboye" agomba kugenzura amashanyarazi mbere yo guhuza ibikoresho.Amabwiriza (yerekanwe 4 na 5) avuga ko "umuntu ubishoboye" agomba kugenzura imbaraga mbere yo guhuza igikoresho.Ibi birimo ibikwiranye nibikorwa bya RCD byose birinda ibikoresho byashyizwe mubikoresho.
Imitwaro y'ibyiciro bitatu harimo inverter (urugero: pompe, compressor, kashe, gusudira, nibindi) bitanga imirongo myinshi kandi yoroshye ya DC yameneka ibangamira RCDs zisanzwe.Ingingo 531.3.3 (iv) isaba gukoresha Ubwoko B RCDs kugirango itange urwego rukenewe rwo kurinda ubwo bwoko bwimitwaro.
“Ugomba gufata ingamba zo kwirinda ibyago byo gupfa cyangwa gukomeretsa amashanyarazi.Ibikoresho by'amashanyarazi bigomba kuba bifite umutekano kandi bikabungabungwa neza. ”HSE ishimangira akamaro k'amashanyarazi mu mabwiriza agenga akazi 1989 no gushyigikira ubuyobozi bwo kugabanya / gukuraho ingaruka ziterwa no gukora nabi kandi zakozwe nabi, zikoreshwa nabi kandi zibungabunzwe.Amashanyarazi mu kazi k'Amategeko yo mu 1989, Ingingo ya 4- (1) “Sisitemu zose zigomba kuba zubatswe igihe cyose kugira ngo hatabaho ingaruka zose zishoboka.”Igitabo gikwiye cya HSE (HSR25) kigaragaza ibisabwa bijyanye: igishushanyo (paragarafu ya 62), ibihe biteganijwe no gukoresha (paragarafu ya 63), ibiranga uruganda, ibikoresho bikingira amashanyarazi… (paragarafu ya 64)), na “Umutekano wibikoresho”.sisitemu biterwa no guhitamo neza ibikoresho byose byamashanyarazi.Sisitemu ”..

Ni ukuvuga, RCD itanga uburinzi, kubwibyo, mugihe uhisemo ubwoko bwa RCD, birakenewe ko uzirikana ibisabwa nibyifuzo byatanzwe muri BS 7671 531.3.3, hashingiwe ku bikoresho bishobora guhuzwa nyuma ya RCD ikingiwe gusohoka.
RCDs na RCDs birakwiriye kurinda umuzunguruko wanyuma / sock: amanota yagenwe arakwiriye cyane cyane kurinda mA 30 guhindurwa bitemewe nabakozi badafite ubumenyi (amashanyarazi) - reba BS 7671 531.3.4.1 CBR na MRCD bifite amanota ashobora guhinduka, birashobora gukoreshwa / umutekinisiye. nkuko byateganijwe - reba ingingo 531.3.4.2 ya BS7671.
ICYITONDERWA.MRCDs zikoreshwa hamwe nibikoresho byananiranye-bigomba rero kwemezwa nyuma yo guterana kwa OEM no guhuza (BSEN60947-2 Umugereka M).Ibi bikorwa kugirango hamenyekane igihe cyo guhagarika igihe cyose cya MRCD + MCB + S / Urugendo cyangwa U / Kurekura inteko mugice cyikizamini cyanyuma cyo guterana:
Urebye uko ibintu bimeze nabi byubatswe hamwe ningaruka nyinshi zo gukoresha ibikoresho byamashanyarazi hanze, amategeko aroroshye: ibikoresho bigomba kuba bikwiriye gukoreshwa, kubungabungwa neza no kubungabunga umutekano.Ibi birimo guhitamo ubwoko bukwiye bwa RCD, kurinda neza ibikoresho nka RCDs kubidukikije, no kubikomeza neza.Kugenzura buri gihe no gusuzuma kugirango RCD itanga urwego rukenewe rwo kurinda kandi ibereye ibikoresho bihujwe.Mbere yo guhuza ibikoresho bishya na switchbo iriho - Amabwiriza ya HSE arasaba "umuntu wujuje ibyangombwa" kugirango agerageze amashanyarazi kugirango yizere neza gukoresha ibikoresho.
