Maitiro Ekusarudza Saizi yeTransformer Oil Containment System

Nhanganyaya​

Mukushandiswa kwema transformer emagetsi epakati nepamusoro, masisitimu ekuchengetedza mafuta akakosha pakuchengetedzwa kwezvakatipoteredza, kutevedzera mitemo, uye kuchengetedzeka kwekushanda. KuJZP, isu tine hunyanzvi mukugadzira mhinduro dzakasimba dzekuchengetedza mafuta dzakagadzirirwa zvinodiwa zvakasiyana zvema transformer eindasitiri uye emagetsi. Gwaro iri rinotsanangura zvinhu zvakakosha uye nzira dzekusarudza saizi yakakwana yema transformer ekuchengetedza mafuta, kuve nechokwadi chekuti zvinoenderana nemitemo yepasi rose uye zvinodiwa zvepurojekiti.

Zvinhu Zvikuru Zvinokanganisa Kukura KwemaSisitimu Ekuchengetedza​

 

Vhoriyamu yemafuta eTransformer​

 

Nheyo Yepfungwa: Sisitimu yekudzivirira inofanira kugamuchira 100% yehuwandu hukuru hwemafuta etransformermumamiriro ezvinhu akajairwa uye 110% panguva yemoto(kusanganisira mvura yekudzimisa moto nemvura inonaya)

 

Muenzaniso weKuverenga:

 

Transformer ye110 kV ine simba remafuta rematani makumi matatu (≈34 m³) inoda huwandu hwemushonga wekudzivirira 37.4 m³(34 m³ × 1.1) kuti isangane nezvinodiwa zvekuchengetedza moto.

 

Mutemo weMutemo:

 

GB50060-2008inorayira kuti masisitimu ekudzivirira Transformer yekunzes ine simba remafuta ≥1,000 kg inofanira kutakura60% yehuwandu hwetangi gurukana kupatsanurwa kwemafuta nemvura kwaitwa.

 

Mamiriro Ezvinhu Akanangana Nenzvimbo​

 

 

Kuiswa Mukati vs. Kunze:

 

Matransformer emumba (semuenzaniso, muzviteshi zvemagetsi) anowanzoda kuchengetwa kudiki nekuda kwenzvimbo dzakadzorwa, nepo masisitimu ekunze achifanira kutarisisa kunaya kwemvura uye kupenya kwevhu.

 

Nzvimbo dzekuchengetedza moto:

 

Chengetedza daro diki remamita 1.5pakati pematransformer nemadziro anobvira moto, uye Mita imwe kupfuura mipendero yetransformeryekupararira kwemvura yemoto

 

Zvinhu zveGeotechnical uye Environmental​

 

Kukwanisa Kutakura Ivhu: Ongorora rudzi rwevhu (semuenzaniso, ivhu, matombo) kuti uone kugadzikana kwehwaro uye zvinodiwa pakudonhedza mvura

 

Kuwanda kwemvura: Kune masisitimu ekunze, verenga huwandu hwemvura inonaya uchishandisa data remamiriro ekunze emunharaunda (semuenzaniso, 100 mm/awa munzvimbo dzinopisa).

 

 

Maitiro Ekuita Saizi Nhanho Nenhanho​

 

Sarudza Huwandu Hwakanyanya hweMafuta​

 

Ongorora mifananidzo yehunyanzvi hwe transformer kuti uone huwandu hukuru hwemafuta (semuenzaniso, marita zviuru gumi eyuniti ye 60 MVA).

 

Shandisa Zvinodiwa Zvemutemo​

 

Kutevedzera SPCC: Pakuisa zvinhu muUS, tevera mutemo weEPA we110% (huwandu hwemafuta + 10% freeboard)

 

Mitemo yeChina:

 

GB50053-2013: Inoda 20% yekudzivirira ma transformer emukati ane oiri ≥100 kg, zvichikwira kusvika 100% kana mvura isingashande.

 

Verenga Vhoriyamu Yekuchengetedza​

 

Fomura:

 

Mukatihuwandu hwakazara​=(Mukatimafuta​×1.1)+(Mukatimvura × 0.35)

 

V_mvura: Huwandu hwemvura yemoto (nzvimbo yepamusoro × mwero wekuyerera × nguva).

 

0.35: Chikamu chisina chinhu chekuchengetedza kwakazara nejecha (40% porosity)

 

Dhizaini yeVashanduri Vakawanda​

 

 

Unganidza huwandu hwemafuta ematransformer akaunganidzwa uye wedzera huwandu hwe20% hwekuwedzerwa kwemafuta mune ramangwana.

 

 

Maitiro Akanakisisa Ekugadzira Sisitimu Yekuchengetedza Zvinhu​

 

Kusarudzwa Kwezvinhu​

 

Konkriti Yakasimbiswa: Inoshandiswa mukati meimba nekuda kwekusapisa uye kugara kwenguva refu.

 

Mapaipi eGeomembraneShandisai HDPE liners munzvimbo dziri panze kudzivirira kudonha kwemvura muvhu

 

Magadzirirwo eGravel Layer​

 

Ukobvu: ≥250 mm.

 

Saizi yeDombo: dhayamita ye50–80 mm kuti pave nekupinza kwakanaka uye kudzivirira moto

 

Kuparadzanisa Mvura neOiri neMvura​

 

 

Isa mapaipi akaboorwa ane dhayamita ye ≥150 mm uye sikirini dzesimbi dzisina ngura kuti usefe tsvina.

 

Kuramba Kudzikiswa Kwepasi Nemhepo​

 

Gadzira mabhaudhi ekudzivirira kuti agare kwenguva refu 0.4 static friction coefficientuye mitoro yakanangana nenzvimbo dzekudengenyeka kwenyika

 

 

Mhedziso​

Kusarudza saizi yakakodzera yemuchina wemafuta etransformer kunoda kuongororwa kwakanyatsojeka kwehuwandu hwemafuta, mitemo yemutemo, uye mamiriro enzvimbo. KuJZP, tinoshandisa maturusi einjiniya epamusoro uye nzira dzakanakisisa dzeindasitiri kuti tipe masisitimu emuchina wekuchengetedza anokoshesa kuchengetedzeka, kutevedzera mitemo, uye kushanda zvakanaka. Batana nesu kuti uve nechokwadi chekuti uri pakati nepakati uye wepamusoro-soro.Madhiragi eVoltage zvinodzivirirwa kubva pakudonhedza mvura, moto, uye njodzi dzezvakatipoteredza.
