Magetsi eVhiki Nevhiki: Chii chinonzi Gas-Insulated Switchgear (GIS)?
Tsananguro Yepakati: Chiteshi Chidiki, Chakabatanidzwa
Gas-Insulated Switchgear (GIS) chishandiso chinopa simba remagetsi rakawanda. Chinosanganisira zvikamu zvese zve substation—kunze kwe main power transformer—zvakaita se circuit breakers, disconnectors, earthing switches, instrument transformers, busbars, uye surge arresters, mukati me sealed metal enclosure yakazadzwa ne sulfur hexafluoride (SF6) insulating gas. Saka, GIS bay imwe chete inoshanda se connective high-voltage power distribution devices. nzvimbo diki yekuisa zvinhu panzvimbo. Chigadziko chayo chemukati chinoshandisa hunhu hwepamusoro hwekudzivirira kupisa uye kudzima arc-quenching hwegasi reSF6 kuti ribvise zvachose zvikamu zvese zvipenyu kubva kune nharaunda yekunze.
Kuongorora Chimiro: Zvivako zveModular & Zvikamu Zvikuru
GIS haisi tangi hombe chete; mukati mayo makakamurwa kuita akawanda akazvimiririra zvikamu zvegasi zvichibva pakushanda kwayo. Semuenzaniso, circuit breaker inowanzogara muchikamu chayo che high-pressure; mabhazi, ma voltage transformers, uye surge arresters zvinowanzova nezvikamu zvakasiyana. Uku kupatsanurwa kwezvikamu kunobvumira kuparadzaniswa, kugadziriswa, kana kuzadzazve gasi kwezvikamu zvega pasina kukanganisa mashandiro ezvimwe. Zvikamu zvese zvemagetsi zvakabatana kuburikidza mabhazi emukati (mabhazi) mukati menzvimbo yakavharirwa, zvichibvisa zvachose kubatana kwekunze kuri pachena kunowanikwa muAir-Insulated Switchgear (AIS) yechinyakare. SF6 gas density monitors inogara ichitevera kumanikidzwa muchikamu chimwe nechimwe, ichiva nechokwadi chekuti insulation yakasimba.
Mabhenefiti Akakosha & Mashandisirwo Akajairika
Kushanda kwakanaka kweGIS kunoita kuti isatsiviwe mune zvimwe zviitiko. Chinhu chikuru chakanakira ndechekuti tsoka diki kwazvo, zvinoda chete 10% kusvika 30% yenzvimbo yepasi zvichienzaniswa nechiteshi chekare cheAir-Insulated Substation (AIS) chine simba rakaenzana. Izvi zvinoita kuti ive yakakodzera nzvimbo dzemaguta dzine nzvimbo shoma, mukati mezvivakwa zvirefu, munzvimbo dzakakwirira dzemakomo, kana nzvimbo dzakasvibiswa zvakanyanya. Uyezve, chivakwa chakavharwa zvizere chinopa kuvimbika kwakanyanya kushanda (huwandu hwekukundikana hunogona kuderera ne60-80% pane AIS) nezvinodiwa zvishoma zvekugadzirisa (nguva huru dzekugadzirisa dzinogona kudarika makore makumi maviri), uye inobvisa zvachose njodzi dzekuvhundutswa kwemagetsi ekunze uye moto. Nekuda kweizvozvo, GIS chikamu chikuru mumagridi emagetsi emazuva ano uye nzvimbo dzakakosha pa110kV uye pamusoro pemazinga emagetsi, kunyanya uko kugomara, kuvimbika, uye kuchengetedzeka zvinonyanya kukosha.
Nezvedu:
Mingri Electric Co., Ltd. ikambani inotungamira mukupa zvikamu zvemagetsi zvemhando yepamusoro uye mhinduro, inyanzvi mukugadzira switchgear, circuit breakers, switches, nezvimwewo. Takazvipira kupa zvigadzirwa zvitsva zvinogutsa zvinodiwa neindasitiri yemagetsi yepasi rose.
