Switchgear unit trust (CRU): mefuta e, litšobotsi tse, kgetho

Sehlooho sena se tla fana ka boitsebiso bo mabapi le ho switchgear feletseng. litšobotsi tse botekgeniki bona, mefuta e 'me ho khethoa ha le tla fuoa.

Boholo

Switchgear unit trust (CRU) - e sesebediswa e entsoeng ka mapolanka, tse kenyelletsoa ka sebopeho:

• mechine e qala le matla-timetsang thepa ya taolo ya;
• le sesebediswa tšireletso ea;
• ts'oarello sesebediswa;

Hammoho le dikarolo tse ding boikhethelo, ba bokana le loketse ho sebelisoa.

Sepheo se seholo ke ho fumana le ho li aba ka ho eketsehileng motlakase dinetweke tseo tse tharo-mohato ka maqhubu a ho sebelisa mehaho ea 50 Hz le gagamalo ba fetang 1000 V.

Switchgear unit trust (CRU) e arotsoe mefuta e 'meli, ka ntle le ka hare ho instola. Bakeng sa limela, 屋内 di kenngoa ka kapa jareteng ena. disebedisweng tse joalo ba ile ba bokana le busbar ena. Ha sebelisoa bakeng sa ho voltages bueloang hodimo 35 kV sebelisoa moea dinetweke tseo ho itšehla thajana 110 kV kwahelang e li sireletsang serameng khase.

E le busa, ka switchgear tšebeliso fapoha morao-rao se phahameng-gagamalo lephaka e le tšireletso le ho switjha sesebediswa, empa ho na le ho feta khale dimela tse hlomamisa fapoha oli.

Kabo likhabote, switchgear RN 6 li etsetsoang e le tšebeliso ntle le ba arotsoe ka mefuta e 'meli tsa tshebetso: phethola tsoa, eo ho eona likarolo tsohle le dikarolo ba tsepame boto e khethehileng,' me ema, moo likarolo tsohle le dikarolo hlomamisa bakeng sa bophelo ba nako e telele tšebeletso.

Tlhomamiso ea tlhomamiso ntle

Switchgear ntle tlhomamiso tlameha ho itokisetsa bakeng sa kopano, kahoo pele tsa motheo tsohle raloa. Lisele tse susumelletsa foromo bokellaneng pele maqheka ohle a beha. Ka mor'a moo pakolla le ka motlakase phethola tsoa matlo eo switchgear e hlomamisa. Behantsha seleng e le tokisetso ea ho latela morero oa. Tlhomamiso e qala ka fetisisa. Hang netefalitsoeng ho hlongoa e nepahetseng ea raka eo, e behiloeng e tlang. Ho ke ke bohlokwa hore lisele ha ba na ho ema ka hlaha ka lehlakoreng le ya.

Bakeng sa mela holim'a marulelo a e-hloa mekoalaba masakaneng hlomamisa. Ho boetse ho hlokahala hore ho beha mabone ea moo haufi le e mong le e seleng. Phahameng-gagamalo kabel dessyecik mola qetello switchgear tsepame ho se fumaneng ka lemati ka morao ea raka ho. Ka mor'a moo switchgears tlhomamiso ntle loketse bakeng sa tshebetso.

Design

switchgears balwa (KRU) 6/10 kV gagamalo lokela ho netefatsa tshebetso tloaelehileng ea thepa ea motheo e tsohle mounted ho eona. KRU tšoanang le ponahalo e ho kgolo seleng ea tšepe, ka hare tse mounted switchgear, ts'ireletso le disebediswa tsa ho ea thusang. Sekoahelo le ka ntle la sele bōpiloe ka maqephe a tšepe, ho e etswang ho eketsa matla a mehaho le tshireletso khahlanong le tse kgutshwanyane-oa potoloho morao-rao tsa lisebelisoa tse ling le teng haufi le moo.

Kabo likhabote, switchgear RN 6 le hlomeletsoeng ka futhumatsang khethehileng sebakeng seo, eo ka eona hona joale-lekanya le disebediswa tse ka tsela e tloaelehileng sebetsa nakong ea mariha.

Tobileng le ho switjha bokgoni

Switchgear unit trust (CRU) 10 kV o na le tsena tse latelang ya data ka lebitso:

• phepelo bueloang gagamalo - 6, 10, 35, 110 KW;
• liindasteri tsa ho sebelisa mehaho mola maqhubu a - 50 Hz;
• Sebetsa Current - 630 A;
• tripping jwale - 12,5, 20, 25, 35, 40 Ka;
• kwahelang - moea;
• thaepa oa potoloho - e lephaka;
• thaepa jwale transformer - pushing-6;
• thaepa matla transformer - TM-25;
• Drive Type - motlakase.

Oa potoloho switchgear hanyetsa ikemiselitse thehiloeng entsprechen tsa thepa eo e hahiloeng ka sesebediswa sa switjha mounted ho e khanna. Ho switjha thepa, e leng e behoa ka switchgear sa, lokela ho ka tsela e tloaelehileng sebetsa ka mojaro rated le mamella teko potoloho ka phahameng pshatloa jwale, tse beha e tobileng a maqheka hare.

Setho sekwahelo le tekanyo ea ho tshireletso ya

Retractable elements eo ho thepa switjha, ka tšoaetsanoang ka bobeli ka letsoho le mechanically. Ka ho etsa joalo, koloi e lokela ho feta tseleng e sa esita le barbotage kaha e na le e ngata haholo ea boima ba 'mele.

likhabote All switchgear lokela ho ba phutholohile nakong buuoa le li etselitsoe matšeliso tlhomamiso, ho lokisa le Phetolo ya likarolo. Ka ho fetisisa likhabote switchgear nakong ea ka motlakase Sliding phethola tsoa lisele ka boemo ba sebetsa ho buleha ho mabitso a mang le e tsitsitseng ea balebeli ba potoloho ba ka sehloohong disconnector notlela likhareteneng khethehileng.

Ho itšetlehile ka hore kopo ya, ho hlongoa ka ba mokgwa o fapaneng wa tshebetso. CRU lokela ho iphaphatha eclectic le phetha molao mehaho matla, kwahelang le ho hanyetsa maemo mabifi ho sebelisa mehaho. Category tsa bodulo Crewe:

• V3 - etselitsoeng ho sebetsa libakeng tse ka ajoa tsa tlhaho moea;
• V4 - etselitsoeng likamore le boemo ba leholimo maiketsetso.

Tsela eo le entseng switchgear ke ho fana ka botsitso nakong loebehlana eo etsahala nakong ea ho switjha ka le theoha fapoha phahameng-gagamalo, hammoho le ha ba fallela unit. Tabeng ena, lisebelisoeng bohle ba lokela ho sebetsa, 'me lesokoana tšireletso ea sa etsahala nakong tshebetso ka lebelo le ka lebitso.

Switchgear ka etsoa bakeng sa maemo a fapaneng a klimate a ka tshebediso ya futhumatsang sebakeng seo kapa tsidifatso.

Ha ho sebetsa le switchgear hlokahale nako ho hlophisa tlhahlobo botekgeniki le tlhokomelo ya thepa, e leng e behoa ka seleng, hammoho le tsa mathata.

Tsamaisoa ke mosebetsi oa thepa e amehang ka ramotlakase mosebetsi kapa basebetsi ba sebetsang ho hlongoa. Ho latela seo a se hlokang hona joale polokeho, ho sebetsa le ditlhomo motlakase hoa lumelloa motho a le mong, kahoo ha ho sebetsa le KRU hloka bonyane ba babeli.

Basebetsi ba ba ba kopanela ho hlongoa lokisa tlameha ho koetlisoa le ho ba le mamello le sehlopha se tlaase ho feta IV, 'me le bona ba lokela ho tseba mabapi le thepa e ka phutheho switchgear,' me ho fana ka mekgwa motlakase sebetsa likarolo.

Tlhomamiso ka gagamalo bueloang tse 35 kV

Switchgear phahameng gagamalo letoto la lihlooho tse BM-4 sebelisoa bakeng sa phetiso ya matla ho dinetweke tseo tse tharo-mohato le liindasteri timang maqhubu a ya 50 Hz le e gagamalo bueloang tse 35 kV.

Switchgear seleng e ke sebopeho sheathed le maqephe galvanized tšepe tse ikopanya ke ao cheseletse kapa rivet. Ka hare mounted fapoha phahameng-gagamalo, gagamalo baru, switchgear, ditlabelwa le isolator.

Joalo switchgear etselitsoeng tšebeletso peli tsela. Ha hlomamisa ka e nyenyane-boholo bo lekaneng dimela hlahisa fetotsoeng KRU-tsela tšebeletso. Ho boloka mocheso ka lisele tsa tsona li, ho na le foufatsa. Hape le hore nka imoloha khatello, e ka hlaha ka taba ea mekhoa tshebetso tshohanyetso kapa molato maqhubu senya-valve tse hlomamisa marulelo a ka seleng.

Sethusathuto letšoao K-63

Switchgear letšoao K-63 e etsoa ka 'mele oa tšepe rigidly tsitsitseng ho ea litšehetsong, ka hare e leng kakaretso ho Sireletsa switchgear le transformer thepa. Switchgear mofuta switchgear K-63 hammoho le batho ba bang, ba ne a rerile hore phetiso le kabo ya jwale motlakase ka dinetweke tseo tse tharo-mohato le maqhubu a indasteri ea 50 Hz le nang le gagamalo bueloang la 6 kV.

Tšobotsi e 'ngoe ea KRU K-63 ke hore e ka sebelisoa e le sesebelisoa sa transformer. Ka sehloohong disebediswa tsa ho switjha K-63 di se phahameng-hona joale e fapoha ka ho BB / Tel sebelisa phetela electromechanical kapa MPD.

Lisele tsa K-63 li etselitsoe bakeng sa tlhomamiso ka jareteng, 'me transformer e ka fumaneha ka ntle. K-63 o ile a bokella le tsamaiso le 'ngoe busbar, ho eo motlakase feptjoang ka phahameng-gagamalo switchgear seleng ea ho kena ka hore o ile a lokisetsa ka holim'a teraka.

Unit K-594 cha: seriti

Switchgear KRU letšoao K-594, joaloka seta tsohle ka holimo, a sebetsa ka gagamalo tsa dinetweke tseo kV 6-10 le oa maqhubu a ho sebelisa mehaho ea 50 Hz.

E le busa, KRU K-594 li sebelisoa substations, dimela matla, libaka tsa temo le liporo. Switchgear kopano KRU-594, theko ea eona e itšetlehile ka mofani wa thepa le theko ea tikolohong eo, o phethahetseng bakeng sa tlohang Motors phahameng-gagamalo le tse ling tse mechine ea motlakase. Melemo e ka sehloohong ea switchgear ke tsena:

• actuators tsohle tsa motlakase di bokane ka seleng e le 'ngoe' me ea phethoa ka fekthering;
• Ho eketsa polokeho ya semela ka boeona e, hammoho le ea basebetsi ho sebetsa;
• kaofela ha likarolo rarahaneng ka ho fetisisa ba mounted ka phethola tsoa ka koloi, e leng ho fokotsa ho rarahana ha mosebetsi ka ho boloka thepa;
• lisele tse KRU ha bulky, kahoo ba ile ba haholo boloka sebaka ka kamoreng.

Switchgear unit trust (CRU) K-594 letoto la lihlooho tse nang le tobileng tse ka fetola tabeng ea eketseha kapa aa fokotseha ka balwa indices ka lebitso la bareki, e tla amana switchgear.
