Iyo switchboard, panelboard, uyeswitchgearndiyo midziyo ye overcurrent kudzivirira yemagetsi redunhu. Ichi chinyorwa chinotsanangura musiyano wakakosha pakati pemhando nhatu idzi dzemagetsi system components.

Chii chinonzi Panelboard?

A panelboard inhengo yemagetsi ekupa magetsi inokamura chikafu chemagetsi kuita maseketi anotsigira uku ichipa fuse yekudzivirira kana yedunhu redunhu redunhu rega rega munzvimbo yakavharirwa. Iyo inoumbwa nepaneti imwe chete kana boka remadziro akaiswa madziro. Chinangwa chebhodhibhodhi ndechekupatsanura simba kuita masekete akasiyana. Iwo akafanana ne switchboards, asi chimiro ndicho chinhu chinovasiyanisa.

Chii chinoita kuti mapaneru asiyane ndeyekuti anogara akaiswa kumadziro. Nzira chete inogoneka yekuwana mapaneru ndeyekumberi. Humwero hwemapuranga emapuranga akadzikira zvakanyanya pane switchboard uye switchgear, 1200 Amp max. Panelboards anoshandiswa pamagetsi anosvika 600 V. Kunze kwezvikamu zvitatu zvemagetsi emagetsi, mapaneru ndiwo akachipa uye madiki muhukuru.

Zvishandiso zvePanelboards

Panelboards anowanzo kuwanikwa munzvimbo yekugara kana diki yekutengesa uko kudiwa kwemagetsi hakuna kukwira zvakanyanya. Mashandiro akajairika epabhodhi ndeaya:

• Zvivakwa zvekugara, zvekutengesa, uye zvivakwa zvidiki zvemaindasitiri. Mudzimba uye mumahofisi, mapaneru anoparadzira magetsi kune zvikamu zvakasiyana zvechivako kubva kune chikuru. Vanogona kugovera magetsi kuHVAC masisitimu, masisitimu emwenje, kana midziyo yemagetsi mikuru.
• Zvivako zvehutano. Munzvimbo dzehutano, mapaneru anoshandiswa kune zvese zvikumbiro zvakatsanangurwa pamusoro pezvivakwa zvekugara uye zvekutengesa, pamwe nekugovera magetsi emidziyo yekurapa.

Zvichienderana nechishandiso, mapaneru anogona kukamurwa kuita akati wandei ma subtypes, anosanganisira mwenje mapaneru uye simba rekugovera mapaneru. Iyo main panel, subpanel, uye fusebox ese marudzi emapaneru.

Panelboard Zvikamu

• Main breaker
• Circuit breaker
• Mabhawa

Chii chinonzi aSwitchboard?

Switchboard mudziyo unotungamira magetsi kubva kune imwe kana mamwe masosi ekupa kune akati wandei madiki ekushandisa. Iko kuungana kweimwe kana kupfuura mapaneru, imwe neimwe ine switch inobvumira magetsi kudzoserwa. Nekuti iri gungano, switchboard inogona kukwidziridzwa chero nzvimbo yebasa. Chinhu chakakosha cheswitchboards ndechekuti ivo vanowanzo sanganisira overcurrent kuchengetedza kune avo ekupa maseketi uye akaiswa pasi. Izvo zvikamu zve switchboard zvinoitirwa kudzoreredza simba.

Chii chinosiyanisa switchboards kubva kune mamwe magetsi masisitimu anotsanangurwa pazasi ndechekuti switchboard inomiririra gungano rezvikamu. Iyo voltage rating ye switchboard masisitimu ndeye 600 V kana pasi. Switchboards anowanikwa kuitira sevhisi kubva kumberi nekumashure. Maswitibhodhi anonamira kuNEMA yakajairwa PB-2 uye UL mwero -891. Maswitchboards ane mamita anoratidza huwandu hwesimba rinopfuura nemaari, asi haana chero otomatiki kuchengetedza zvikamu.

Zvikumbiro zveSwitchboards

Kunge mapaneru, switchboards anoshandiswa mune zvekutengesa uye zvekugara marongero, uye, senge switchgear, anoshandiswa muzvivakwa zveindasitiri. Switchboards anoshandiswa kudzoreredza magetsi main distribution equipment.

Switchboards anodhura kupfuura mapaneru asi akachipa pane switchgear. Chinangwa cheswitchboards ndechekugovera simba pakati pezvakasiyana zvinyorwa. Mhando dzema switchboards dzinosanganisira general-chinangwa switchboards uye fusible switchboards.

Switchboard Zvikamu

• Panel uye mafuremu
• Dziviriro uye kudzora michina
• Swichi
• Mabhawa

Chii chinonzi aSwitchgear?

Switchgear inosanganisa magetsi ekubvisa ma switch, fuse, kana mabreaker breaker kudzora, kudzivirira, nekutsaura midziyo yemagetsi.

Switchgear inosiyana kubva kune switchboard uye mapaneru nekuti inosanganisira ega zvinhu. Midziyo inhengo ye switchgear inoshandiswa kubatidza nekudzima magetsi.

Switchgear inoshandiswa kubvisa-energize michina kubvumira basa kuti riitwe uye kujekesa kukanganisa kuzasi. Inowanzo shandiswa muzvigadziriso umo magetsi makuru anoda kugovaniswa pakati pezvimedu zvakawanda zvakasiyana zvemidziyo, zvinova masisitimu ekutengesa emagetsi akasiyana (akaderera, epakati, uye akakwira). Switchgear yakashongedzerwa nezvikamu zvinoita kuti otomatiki chengetedzo.

Switchgear ndiyo inodhura zvakanyanya uye yakawedzera zvakanyanya zvichienzaniswa nepanerubhodhi uye switchboards. Iyo voltage rating ye switchgear inosvika 38 kV, uye ikozvino chiyero inosvika 6,000A. Switchgear inotevera ANSI mwero C37.20.1, UL mwero 1558, uye NEMA mwero SG-5.

Pakupedzisira, switchgear inogona kushandiswa kunze uye mukati. Mhando dze switchgear dzinosanganisira low-voltage, medium-voltage, uye high-voltage.

Zvikumbiro zveSwitchgear

Switchgear inonyanya kushandiswa kudzora mitoro yemagetsi. Zvishandiso zvakajairika zve switchgear zvinosanganisira:

• Simba uye kushandura midziyo, kunyanya huru yekugovera michina (transformers, jenareta, magetsi network, nezvimwewo).
• Kuzivikanwa kwechikanganiso mumagetsi emagetsi uye kukanganisa panguva isati yawanda
• Kudzora kwemidziyo mumagetsi emagetsi uye magetsi ejenareta zviteshi
• Transformer control mumashandisi ekugovera masisitimu
• Kudzivirirwa kwezvivakwa zvakakura zvekutengesa uye data data

Zvikamu zveSwitchgear

• Draw-out breakers: kushandisa draw-out breakers ne switchgear kunodzivirira kudzima gadziriro yemagetsi kuitira kugadzirisa.
• Simba rekushandura zvikamu: mavhiriki ematunhu, fuse, nezvimwe. Izvi zvikamu zvinotarisirwa kuputsa simba mudunhu.
• Simba rekudzora zvikamu: control panel, transformers, kuchengetedza relays. Izvi zvikamu zvakagadzirirwa kutonga simba.
