MNS GCS Low Voltage Withdrawable Switchgear
Uguhlo lwesikhephe swebuyebo Langsung ulwazi oluhle lokushicilela okubhekisiswa ngezinye izikhathi ezifanekese zokusebenza kanye nokusebenza okusetyenziswa ephakathini. Wavela amandla amaningi nokuthiwe kanye nokuphucukekelayo. Iguhlo lwenziwe ngokulandelana, uphenyo olunqapho ukuvamile kwezinhlobo zesithunzi nezinhlobo zokusebenza, ukuhlola, uhlobo olukhulu lokusebenza, kunye nokufakelwa kakhulu. Kulula kulapho kukusetshenziswa umkhombomthi wokugcina i-AC futhi ukusetha imotshani yokusebenza. Kuyahlonipha izindlela ezintsha, amasentora othisha amadatha, izindlela zephethefumelela, umetali, kunye nemibuzo yezindawo ezimbili.

Izici Zomkhiqizo:
❖ Ifyo yamathuluzi yindlela eyahlukene, ngokushesha esilimi sika-C. Zonke izicatulo zomthuluzi zihlabeleka ukuze kuhlonishwe indawo yokusetyenziswa.
❖ Igabhedvuni elingezansi kwise-switchgear lesiloweni lisilinganiswa ngemibuzo emithathu: indawo yesayithi selondawo (ekuphakheni kwigabhedvuni), indawo yedrawa (ekuphakheni kwigabhedvuni), kunye nozzle ndawo yecayibe (ekusiteni noma ekuphakheni kwesicatshulwa sesibayi). Amandawo amaningiwe ngamaphepu ezide namaphaneli amakhulu amafuthi amahhola olungaphandle kweziphumo zokubhizinisi. Ipheli lemetal ilungaphandle le-drawa ezindleni, incedise ukukholela iinkcukacha ezinikezeliwe ngokusebenza nge-arcing esifumanekayo ngenxa yokufa kwise-switchgear noma iishort circuit phakathi kwebayizini besayithi kunye nokuba noma amacircuits.
❖ Ukubuyekeza kwezinto zokugcina ukulawula amanqaku okuphakathi kunye nokuphela: ukuhlala esiphezulu kunye nokuhlala esijini, ukuhlala esiphezulu kunye nokuhlala esijini, ukuhlala esijini kunye nokuhlala esiphezulu, ukuhlala esijini kunye nokuhlala esijini.
❖ Amanqaku akhawukile kunye nesibhedlela esisetshe. Ngenqanawe ye-25mm, isiphumo kunye namandlu wokuhambisana akwaziwa ngokufanelekayo ukumisa izidingo zokusebenzisa isistimu.
