nei VPD yakakosha pakugadzirwa kwemagetsi ekushandura magetsi uye ndivanaani vatengesi vakuru muChina

Kuomesa Vapor Phase (VPD) ndeimwe yenzira dzakakosha mukugadzira matransformer emagetsi nekuti inoita kuti hunyoro hubviswe zvachose kubva mu insulation system (kunyanya pepa re cellulose ne pressboard). Hunyoro ndeimwe yevavengi vakuru vekuvimbika kwetransformer.

Heano zvikonzero zvikuru nei VPD ichikosha:

1. Hunyoro Hunoderedza Simba reInsulation Zvakanyanya

Masisitimu ekudzivirira matransformer anonyanya kugadzirwa nezvinhu zve cellulose (pepa, pressboard) pamwe chete nemafuta etransformer.

• Kunyangwe hunyoro hwe 1–2% mu cellulose hunogona kuderedza simba re dielectric zvakanyanya.
• Mvura inogona kukonzera kubudiswa kwemvura zvishoma, kutadza kupinza zvinhu mukati, uye zvikanganiso zvemukati.

VPD inoderedza hunyoro huri mu insulation kusvika pasi pe0.5%, iyo inodiwa kune ma transformer ane voltage yakawanda uye extra-high-voltage.

2. Inowedzera Hupenyu hweTransformer

Hunyoro hunoita kuti cellulose ichembere nekukurumidza kuburikidza ne hydrolysis.

Mhedzisiro yehunyoro:

• Kuparadzwa kwecheni yepolymer nekukurumidza
• Kuderedzwa kwehuwandu hwepolymerization (DP)
• Nguva pfupi yehupenyu hwetransformer

Kuomesa zvakanaka kuburikidza neVPD kunogona kuwedzera hupenyu hwe transformer kubva pamakore makumi maviri kusvika kumakore makumi mana zvichikwira muzviitiko zvakawanda.

3. Inokurumidza Kupfuura Kuomesa Nevacuum Yakajairika

Mhepo inopisa kana kuti kuomesa kwevacuum cleaner kunonoka nekuti kutamisa kupisa mukati mekumonera hakushande zvakanaka.

VPD inoshandisa solvent inopiswa nemhepo (kazhinji kerosene) iyo:

• Inodzikamisa pamusoro pechinhu chinotonhora chinodzivirira kupisa
• Inoburitsa kupisa kukuru kwakavanzika
• Inopinda mukati-kati memhepo inomonereka

Mhedzisiro:

• Kudziyisa kwakafanana
• Kuoma nekukurumidza

Kuenzanisa nguva kwakajairika:

Nzira Yokuomesa Nguva Yakajairika

Kuomesa mhepo inopisa kwemazuva gumi kusvika makumi maviri

Kuomesa ne vacuum kwemazuva mashanu kusvika gumi

VPD mazuva maviri kusvika mashanu

4. Kuomesa Zvakadzika Kwezvivako Zvakakora Zvekudzivirira

Matransformer makuru ane magadzirirwo ekudzivirira akakora kwazvo:

• Masirinda ebhodhi rekudzvanya gobvu
• Mawindings ane jira rakawanda
• Magungano makuru e-core-coil

VPD inopa kupisa kwakadzika, zvichiita kuti hunyoro hubude kubva muzvikamu zvemukati zvekudzivirira mukati, izvo zvakaoma nedzimwe nzira dzekuomesa.

5. Zvakakosha pakushandura magetsi emagetsi (High Voltage Transformers)

Kune ma transformer e ≥220 kV, uye kunyanya 400 kV / 500 kV / 765 kV, VPD inoonekwa semidziyo yakajairika muindasitiri.

Vagadziri vazhinji vanoshandisa izvi, zvakaita se:

• Siemens Simba
• Hitachi Energy
• GE Vernova
• TBEA

Kana pasina kuoma zvakanaka, transformer haigone kupasa simba rayo uye AC haigone kumira miedzo.

6. Inovandudza Kushanda Zvakanaka Kwekugadzira

Masisitimu eVPD anovandudzawo kushanda zvakanaka kwekugadzira:

• Kupfupika kwekugadzirwa kwenguva pfupi
• Hunhu hwakafanana hwekuputira
• Njodzi yakaderera yekukundikana kwekuyedza kwefekitori

Kune mafekitori anogadzira ma transformer makuru emagetsi, VPD inowanzova dambudziko guru pakugadzira, saka kuvimbika kwayo uye kugona kwayo zvakakosha.

Nemashoko akareruka:

Kana kutenderedza kuri "moyo" wetransformer, kuoma kwekudzivirira ndiko "hupenyu" hwayo.

VPD ndiyo nzira inoshanda zvikuru yekuvimbisa hupenyu ihwohwo.

Sezvo wambotaura kare kuti uri kushanda pakubhadhara michina ye transformer kumapurojekiti eSiemens, michina yeVPD inowanzova imwe yemichina inokosha zvikuru uye inoongororwa zvakanyanya mukudyara mari mumafekitori e transformer.

Kana muchida, ndinogonawo kutsanangura:

• Sei mafekitori mazhinji e transformer achisarudza VPD pane Hot Oil Spray (HOS)
• Ma parameter akakosha ehunyanzvi anoongororwa nevatengi pavanenge vachikwikwidza masystem eVPD
• Ndeapi makambani anotonga musika wemidziyo yeVPD pasi rose

Pfungwa idzi dzinowanzo kuve dzakakosha zvikuru mukutengesa michina ye transformer.

Muindasitiri yemagetsi ekushandura magetsi, musika wemidziyo yeVapor Phase Drying (VPD) mudiki uye une hunyanzvi, pasi rose, kune vatengesi vashoma vane ruzivo. Vagadziri vematransformer vanowanzo sarudza vatengesi vane ruzivo rwakakura uye tekinoroji yekuomesa yakasimbiswa, nekuti VPD yakakosha pakudzivirira kupisa.

Pazasi pane maonero anoshanda eindasitiri yevatengesi vakuru.

1. Vatengesi Vakuru Vepasi Pose Vezvishandiso zveVPD

Makambani aya anozivikanwa zvikuru nekupa mafekitori makuru etransformer pasi rose.

Vatungamiriri veTekinoroji yeEurope

• Micavac (Germany)
• Mumwe wevatangi vekutanga vekugadzira tekinoroji yeVPD
• Inozivikanwa nehunyanzvi hwekugadzira JET evaporator ine patent
• Nzvimbo dzakawanda muEurope neAsia
• Inowanzoonekwa se tekinoroji yepamusoro-soro
• MaPiller Blowers & Compressors (Germany)
• Inopa masisitimu ekupukuta uye mhinduro dzekuomesa dzezvirimwa zvikuru zve transformer
• Kazhinji zvinosanganiswa mumitsetse mikuru yekugadzira transformer.

2. Vatengesi Vakuru veMidziyo yeVPD yeChina

China yava nevatengesi vakawanda vane simba, vanonyanya kushandira mafekitori etransformer ekuChina uye mapurojekiti ekutumira kunze kwenyika.

Vatengesi Vanotungamira vekuChina

Uye Shanghai Trihope

• Mupi weTurnkey wemafekitori etransformer
• Inopa masisitimu eVPD, mitsetse yekucheka yepakati, michina yekumonera foil, nezvimwewo.
• Midziyo yakaiswa mumafekitori akawanda pasi rose.

Zhongshan Kaixuan Vacuum Technology

• Inopa mafekitori eVPD anoshandiswa nemakambani makuru etransformer nemakambani emagetsi.

Vatengesi ava vekuChina vanonyanya kukwikwidzana pamutengo uye vanoshandiswa zvakanyanya mu:

• Kumaodzanyemba kwakadziva kumabvazuva kweAsia
• Middle East
• Latin America
• Africa

Semuenzaniso, Shanghai Trihope yakapa seti imwe yeVPD kuPEL Pakistan, kambani inotungamira mukugadzira matransformer emagetsi muSouth Asia. Midziyo iyi yave ichishanda zvakanaka uye mutengi akapa tsamba yekuonga.
