I-XGN15-24 BOX-TYPE FIXED AC METAL-ENCLOSED SWITCHGEAR
Isishwankathelo
I-DR-XGN-24 ibhokisi-uhlobo lwe-AC yensimbi evaliweyo ye-ring network switchgear sisizukulwana esitsha sokutshintsha komthwalo wesulfure hexafluoride, enokuthi iqwalaselwe kunye nabaphuli beesekethe, ukutshintshela okukodwa, abaguquli bangoku, abaguquli be-voltage, ukubamba umbane kunye nezinye izinto zombane. Ikhabhinethi yonke i-air-insulated kwaye ifanelekile ukuhanjiswa kwamandla okuzenzekelayo. Yintsimbi edibeneyo kunye neyokwandisa i-switchgear evaliweyo. Ineempawu zembonakalo entle, isakhiwo esilula, ubungakanani obuncinci, ukusebenza okuguquguqukayo, kunye nokunxibelelana okuthembekileyo.
Le khabhathi yomnatha womnatha ifanelekile kwisigaba sesithathu se-AC 50Hz, ireyithingi yombane we-12kV ring network network supply power supply, kwaye isetyenziswa ngokubanzi kumashishini kunye nothungelwano lwe-cable ring kunye neeprojekthi zonikezelo lwamandla ombane. Ifaneleka ngokukodwa kwezi ndawo zilandelayo: ukuhanjiswa kwamandla kwiindawo zokuhlala ezisezidolophini, izikhululo ezincinci zesibini, iiofisi zokutshintsha, amashishini oshishino kunye nemigodi, iindawo zokuthenga, izikhululo zeenqwelo moya, i-subways, itonela, ukuveliswa kwamandla omoya, njl.
Iimpawu eziphambili zemveliso
◆Ukwandisa umthamo wetransformer engundoqo kunye nokuphucula umthamo wobonelelo lwamandla kwisitishi esingaphantsi.
◆Ukuphucula amandla okuhambisa amandla kwiintambo zokuhambisa kunye nokunciphisa inani leentambo zokuhambisa.
◆Ukwandisa iradiyasi yobonelelo lwamandla kwiintambo zamandla ombane aphakathi.
Eli nqanaba lombane laliqhutywa kwindawo encinci ngaphambili. Ngokwesicelo seState Grid Corporation yaseTshayina, inqanaba lamandla ombane angama-20kV lanyuswa ngokokulinga kwiPhondo laseJiangsu. Ngoku i-China Southern Power Grid nayo ilungiselela ukukhuthaza inqanaba lamandla ombane angama-20kV eGuangdong nakwezinye iindawo. Kunokuqikelelwa ukuba ekugqibeleni izixhobo ze-24kV ziya kuLawula urhwebo.
