Munzvimbo dzekugadzira maindasitiri, kuchengetedzwa kwekuchengetedzwa kwekugadzirisa michina yemagetsi uye kugadziriswa kwesimba rekugovera magetsi ndizvo zvinhu zvikuru pakugadzirwa kwekuchengetedzwa kwebhizinesi.LOTO (Kuvharirwa/Kuburitswa)Sisitimu iyi, inosanganisira kukiya nekumaka kuti ivhare simba rine njodzi yemagetsi uye kudzivirira kusashanda zvakanaka kwemacircuit breaker, ndiyo "nzira huru yekudzivirira" yekudzivirira kuchengetedzeka kwevashandi uye kudzivirira kudzimwa kwemagetsi. Sekureva kwedata, inopfuura hafu yetsaona dzekugadzirisa magetsi dzine chekuita nekusavapo kana kusashandiswa zvakanaka kwemaitiro eLOTO. Pakati padzo, tsaona dzinokonzerwa nekusashanda zvakanaka kwemacircuit breaker, senge kuvhunduka kwemagetsi, mashort circuit equipment, uye kunyange moto, dzine huwandu hwakakura. Kiyi yecircuit breaker, semudziyo wekukiya wepakati wekubvisa sosi yesimba remagetsi mumaitiro eLOTO, ine chekuita zvakananga nekusarudzwa kwakajairika uye kushandiswa kwakakodzera kwemarudzi akasiyana emacircuit breaker uye chinhu chakakosha icho nyanzvi dzekuchengetedza maindasitiri nevashandi vemagetsi vanofanirwa kuziva. Chinyorwa chino chichapa ongororo yakadzama uye kuunzwa kwemarudzi akasiyana emacircuit breaker kubva pamaonero eLOTO, pamwe nehurongwa hwekukiya, uye kupindura mibvunzo inowanzo shandiswa muindasitiri kubatsira mabhizinesi kugadzirisa kushandiswa kwesystem yeLOTO uye kusimbisa tambo yekudzivirira kuchengetedzeka kwemagetsi emaindasitiri.
Pazasi, ndichaongorora, ndichatanga, uye ndichapa marongero ekukiya emhando dzakasiyana dzemacircuit breakers kubva pamaonero ehunyanzvi hweLOTO.
I. Madiki eDunhu reMaputsi
Ma "circuit breaker" madiki ndiwo midziyo yemagetsi inodzivirira zvakanyanya muma "industrial power distribution systems". Anonyanya kushandiswa kudzivirira overload uye short-circuit, ane saizi diki, ane mwero wekutyoka, uye kushanda zviri nyore. Ndiwo midziyo mikuru yekugovera simba muma "industrial workshops", ma "distributing boxes", uye michina midiki. Mukushanda kweLOTO, ma "circuit breaker" madiki anoshanda se "key node" yekuparadzanisa simba remagetsi pamberi. Kana asina kuvharwa zvinoenderana nemitemo, anogona kukonzera kuti michina yekugadzirisa iri pasi pemvura itange kushanda nekukurumidza nekuda kwevashandi vanovhara circuit breaker zvisirizvo, zvichikonzera tsaona dzakadai sekuvhunduka kwemagetsi, kukuvara kwemidziyo, nezvimwewo. Saka, kukiya kwemuviri kunofanirwa kuitwa kuburikidza nema "special locks" kuti zviite zvinodiwa zveLOTO energy isolation.
Mhando dzakajairika dzema "small circuit breakers":
⑴. Zvemumba: CHINT, DELIXI, VANHU, TENGEN, Nader, nezvimwewo. ⑵. Zvekunze: Schneider Electric, ABB, Siemens, Eaton, Legrand, nezvimwewo.
a. Mamiriro ekushandisa:
⑴. Kudzivirirwa kwemutsetse uye kupatsanurwa kwesimba mumabhokisi madiki ekugovera uye mabhokisi ekudzora michina mumashopu eindasitiri;
⑵. Kugadziriswa kwemagetsi ane simba shoma munzvimbo dzemahofisi nenzvimbo dzekubatsira dzemaindasitiri;
⑶. Kugadziriswa kwemaseketi madiki emapazi uye maseketi emagetsi ekushandisa zvinhu zvakanyatsonaka mumitsetse yekugadzira otomatiki.
II. Muputsi weDunhu reMakesi Akaumbwa
Chinopwanya dunhu chekasi chakaumbwa chine mabasa ekudzivirira kuzara kwemagetsi, kupfupika kwemagetsi, uye kudzivirira pasi pemagetsi. Chine simba rakasimba rekupwanya magetsi uye huwandu hwemagetsi hwakakura. Chivharo chacho chakagadzirwa nezvinhu zvinodzivirira kupisa, izvo zvinogona kudzivirira kusangana nearc. Ndicho chinhu chikuru chehurongwa hwekugovera magetsi mumaindasitiri uye chinoshandiswa zvakanyanya kudzivirira nekudzora michina ine simba rakawanda, kugoverwa kwesimba guru remuworkshop, uye mitsetse yetrunk yekugovera magetsi.
Senzvimbo inokosha yekuparadzanisa simba remagetsi munzvimbo dzemaindasitiri, muchina wekuparadzanisa dunhu wekasi wakaumbwa unobatanidza sosi yemagetsi yemidziyo ine simba guru. Kusashanda zvakanaka kwekuvhara switch kuchakonzera kuburitswa kukuru kwesimba remagetsi, zvichikonzera kukuvara kwakanyanya kwemunhu uye kukuvara kwemidziyo. Saka, panguva yekushanda kweLOTO, zvakakosha kuwana kiyi yakachengeteka kuburikidza nemakiyi ane basa guru uye kubatanidza dziviriro dzakawanda kuti uve nechokwadi chekuti simba rinoparadzaniswa zvakanaka.
III. Muputsi weDunhu reFuremu
Chinopwanya dunhu remafuremu, chinozivikanwawo sechinopwanya dunhu repasi rose, chine simba guru remagetsi, simba guru rekudzikisa magetsi, uye mabasa ekudzivirira akazara. Chinogona kushandiswa nemagetsi nemaoko uye chinonyanya kushandiswa sechinochinja chikuru muhurongwa hwekugovera magetsi emabhizinesi emaindasitiri. Ndicho chikamu chikuru chekudzora nekudzivirira network yese yekugovera magetsi emaindasitiri. Chinopwanya dunhu remafuremu chinodzora simba remagetsi renzvimbo yese yekushandira kana yefekitori. Kushanda kweLOTO (Lockout-Tagout) paLOTO panel ndiko kunonyanya kukosheswa pakuchengetedzwa kwemagetsi emaindasitiri. Kana chikashandiswa zvisirizvo, chinogona kukonzera kudzimwa kwemagetsi kukuru, kukuvara kwemapoka emidziyo, kana kunyange tsaona huru dzekuchengetedza munhu. Saka, zvakakosha kutevedzera maitiro ese eLOTO uye kushandisa makiyi akasimba kuti uwane kupatsanurwa kwakawanda kwemuviri, uye kushandisa musimboti wekuti "ndiani anokiya, ndiani anovhura".
a. Mamiriro ekushandisa
⑴. Chishandiso chikuru chekuparadzanisa simba mukamuri guru rekugovera mafekitori emaindasitiri nemapaki makuru emaindasitiri;
⑵. Kugadziriswa kwesimba remagetsi mumakambani makuru emaindasitiri akadai sekugadzira simbi, magetsi, uye makemikari;
⑶. Main distribution control switches emagetsi makuru ekugadzira otomatiki uye mafekitori akangwara ekushanda kweLOTO.
