Ntawm Nyab Laj ETE & Enertec Expo muaj nyob rau lub Xya Hli ntawm Saigon Exhibition thiab Convention Center hauv Ho Chi Minh City, switchgear thiab transformers tseem yog ob pawg uas tau txais kev nyiam tshaj plaws los ntawm cov neeg yuav khoom. Cov neeg siv khoom los ntawm cov xeev ntug dej hiav txwv tshwj xeeb tau nug seb peb puas muaj kev hloov pauv thiab hloov pauv cov kev daws teeb meem tsim los rau cov ntsev hiav txwv hiav txwv - qhov chaw tshuaj tsuag. Cov kev sib xyaw ua ke -cov neeg tua hluav taws hauv tsev thiab tso tawm- tawm fuses kuj tau nyiam cov neeg coob coob nyob ib puag ncig lub rooj muag khoom, thiab lub sijhawm no ntau tus neeg tuaj xyuas tuaj nrog lub vev xaib duab thiab cov phiaj xwm tiag tiag es tsis yog khaws cov ntawv qhia zoo li xyoo dhau los. Kev faib tawm network hloov kho kev sib tw hauv ntau lub xeev nruab nrab thiab sab qab teb ntawm Nyab Laj tau tshaj tawm tsis ntev los no, nrog 22 kV kab rwb thaiv tsev retrofits thiab hloov cov kev laus poob - tawm fuses accounting rau ib qho tseem ceeb. Transformer-mounted surge arresters thiab low{10}}voltage switchgear kuj tau rub mus rau hauv cov npe khoom. Nyob rau hauv tej yaam num nyob ib ncig ntawm Da Nang, Quang Ngai, thiab Binh Dinh, cov tswv yog kom meej meej qhib rau cov khoom siv txhawb nqa ntug hiav txwv dua li ua ntej. Cov hnub ntawm kev txo qis ntawm tus nqi tsuas yog ploj mus, thiab cov thawj coj kev paub uas paub txog lawv cov khoom tau khawb rau hauv cov ntsiab lus xws li txheej thickness thiab sealing workmanship. Qhov kev laus ntawm lub qhov rooj qhov rooj qhov rooj thiab cov ntsev- cov tshuaj tiv thaiv qib ntawm cov neeg raug ntes yog cov lus nug uas tshwm sim ntau zaus. Qhov kev hloov pauv no cuam tshuam ncaj qha rau cov khoom siv khoom lag luam teeb tsa lawv cov nqi thiab cov lus pom zoo tshaj lij - qhia tawm nrog cov qauv tawm -- cov khoom txee tsis txaus.
Cov phiaj xwm kis tau tus mob raws li Nyab Laj txoj kev npaj tsim hluav taws xob thib yim tseem tab tom mus tom ntej, thiab kev thov rau transformers thiab switchgear yog nce ntxiv nrog rau cov kab txuas ntxiv. Disconnect switches, instrument transformers, and station -class surge arresters for 500 kV and 220 kV transmission projects have been generated nquag nug tsis ntev los no. Hauv Bac Ninh, Hai Phong, thiab lwm qhov chaw thauj khoom, muaj ob peb qhov tshiab 110 kV substations tab tom tsim kho, thiab cov tswv tau tso ntau qhov hnyav rau lub neej- voj voog tus nqi hauv transformer thiab switchgear tenders es tsis yog saib ntawm tus nqi pib xwb. Cov qauv kev lees paub rau cov neeg ntes surges thiab tso tawm - tawm fuses kuj tau sau ntau yam nthuav dav, nrog rau feem pua siab dua ntawm - qhov chaw rwb thaiv tsev tsis kam thiab DC parameter chaw kuaj xyuas dua li xyoo tas los. Qee cov neeg xa khoom tau tshaj tawm tias yog tias cov khoom tuaj txog nrog cov ntawv xeem tsis tiav lossis tsis muaj chaw kuaj xyuas, tsis muaj chaw rau kev sib tham - lawv raug xa rov qab. Kev tswj hwm kev cia khoom kuj tau nruj: cov neeg ntes ntes thiab tso tawm - tawm fuses sab laug ntawm qhov chaw ntau tshaj rau lub hlis yuav tsum tau rov kuaj dua ua ntej tso cai. Qhov kev sib txawv no txhais tau tias cov neeg muag khoom yuav tsum tswj xyuas qhov zoo ntawm lub rooj vag lub Hoobkas txhua txoj hauv kev mus rau tus ncej, thiab qhov kev pheej hmoo ntawm cov ntaub ntawv ploj lawm lossis ua tsis tiav qhov kev kuaj xyuas tau ntau ntxiv.
Hauv Manila, lub teb chaws cov khoom siv hluav taws xob loj tshaj plaws, Meralco, tau qhia txog qhov tshiab ntawm kev faib khoom lag luam kev ntseeg siab kev nqis peev ntawm PhilEnergy qhia xyoo no. Surge arresters thiab switchgear tau muab tso rau siab nyob rau hauv cov npe hloov, nrog coob tus qub roj hloov nyob rau hauv lub nroog cov laus cov cheeb tsam teem yuav tsum tau hloov los ntawm lub tshuab nqus tsev switchgear thiab transformer bays upgraded nyob rau tib lub sij hawm. Lub National Grid Corporation ntawm Philippines (NGCP) tab tom txuas ntxiv nws cov phiaj xwm kev sib kis hauv Luzon, thiab qee qhov 500 kV kab thiab substation expansion ua haujlwm tau nkag mus rau theem kev yuav khoom. Kev thov rau siab -voltage disconnect keyboards thiab surge arresters yog qhov tseeb, thiab cov neeg muag khoom switchgear tau kaw qhov muag ntawm cov kev sib tw loj no. Thaum lub sijhawm ua yeeb yam, cov neeg cog lus hauv zos tau hais tias cov tswv Philippine tam sim no muaj kev nruj heev txog kev ntsuas IP thiab kev tswj xyuas sab hauv hauv kev hloov pauv. Ntug hiav txwv substations tshwj xeeb tshaj yog xav tau surge arrester ua rau luv luv thiab ncaj qha hauv av, thiab kev sib koom ua ke ntawm kev poob- tawm fuses thiab surge arresters yuav tsis raug tswj tsis tu ncua. Cov ntsiab lus no tau hloov kho cov khoom tsim rau cov neeg muag khoom - kev tiv thaiv condensation, ntsev-txhaj tshuaj tiv thaiv, thiab kev yooj yim ntawm kev teeb tsa tau dhau los ua qhov nyuaj rau kev txiav txim siab hauv Philippines.
Tom qab lub caij cua daj cua dub, lub Philippines yeej ib txwm pom muaj nthwv dej ntawm qhov chaw yuav khoom rau poob - tawm fuses thiab ncej- mounted disconnect keyboards. Xyoo no, tom qab ob peb qhov dej nag hnyav hauv Luzon, cov tub lag luam twb tau pib ua khoom lag luam. Kev txiav txim kho xwm txheej kub ntxhov rau hlawv- tawm cov tshuab hloov pauv tau nce zuj zus, thiab hu rau cov neeg tua hluav taws sab nraum zoov thiab qis- cov thawv xa hluav taws xob txuas ntxiv mus. Qhov xwm txheej ntawm kev yuav khoom rov qab yog qhov ceev: leej twg muaj Tshuag ntawm tes yog tus thawj coj. Cov tswv lag luam hauv zos muaj kev txhawj xeeb tshwj xeeb txog kev tiv thaiv cov dej noo hauv cov raj fuse thiab tiv thaiv - cov txheej txheem nplaum, vim tias lawv tau pom ntau dhau ntawm kev poob - tawm fuses tsis poob thaum lawv yuav tsum thiab poob thaum lawv tsis tsim nyog thaum huab cua typhoon. Rau switchgear, rwb thaiv tsev degradation nyob rau hauv lub thib ob circuits tom qab dej nyab yog ib qho teeb meem tshwm sim, yog li kev thov rau ntawm - qhov chaw ziab thiab rwb thaiv tsev kuaj cov kev pab cuam rau switchgear thiab transformers kuj nce thaum lub sij hawm rov qab. Cov nthwv dej ntawm qhov kev thov no cuam tshuam ncaj qha rau cov tswv yim khoom muag - khaws cov qauv siv feem ntau hauv Tshuag ua ntej lub caij cua daj cua dub yeej cov neeg siv khoom ntseeg ntau dua li kev sib tsoo los nrhiav cov khoom tom qab.
Saib ntawm cov ntaub ntawv sib tw los ntawm Nyab Laj thiab Philippines, kev tiv thaiv - corrosion thiab ya raws - pov thawj cov cai rau transformers thiab switchgear yog converging. Nyob rau hauv ntug dej hiav txwv tej yaam num, zoo tib yam galvanized qhov chaw tsis tau txais zoo lawm, thiab stainless hlau ntxiv rau cov txheej txheem kev daws teeb meem yog dhau los ua qauv clauses. Rau surge arresters thiab tso- tawm fuses, cov vaj tsev sib xyaw lossis cov raj sib xyaw ua ke tau dav dav, thiab ntsev- cov kev xav tau tshuaj tsuag tau raug tsa los ntawm 400 mus rau 500 teev mus rau 1,000 teev. Cov tswv tau txais kev nruj dua txog kev tshuaj xyuas tuaj: qhov feem ntawm ntawm - qhov chaw rwb thaiv tsev tiv thaiv thiab DC parameter qhov chaw kuaj xyuas tau nce, thiab cov neeg ntes ntes thiab tso tawm - tawm fuses khaws cia rau ntau tshaj rau lub hlis yuav tsum dhau mus kuaj ua ntej lawv tuaj yeem ntsia tau rau ntawm tus ncej. Qhov kev paub no maj mam pib hauv paus ntawm cov tuam txhab engineering hauv zos. Thaum koj sib sau ua ke cov kev cai tshwj xeeb no, lawv thawb cov tuam txhab tsim khoom kom suav nrog kev tiv thaiv- kev kho corrosion, noo noo{16}} cov ntaub ntawv pov thawj, thiab ua tiav cov ntaub ntawv raws li ib feem ntawm cov txheej txheem ntim khoom. Yog tsis muaj qhov ntawd, nws nyuaj rau tuav txoj haujlwm ruaj khov hauv Nyab Laj thiab Philippines kev lag luam.
