The switchboard, panelboard, leswitchgearke lisebelisoa tsa ts'ireletso ea overcurrent ea potoloho ea motlakase. Sengoliloeng sena se hlalosa phapang ea bohlokoa lipakeng tsa mefuta ena e meraro ea likarolo tsa sistimi ea motlakase.

Panelboard ke eng?

Panelboard ke karolo ea sistimi ea phepelo ea motlakase e arolang phepelo ea matla a motlakase ka lipotoloho tse tlatselletsang ha e ntse e fana ka fuse e sireletsang kapa sekhechana sa potoloho bakeng sa potoloho ka 'ngoe sebakeng se tloaelehileng. E na le phanele e le 'ngoe kapa sehlopha sa liphanele tse kentsoeng leboteng. Sepheo sa panelboard ke ho arola matla ka lipotoloho tse fapaneng. Li tšoana le li-switchboards, empa sebopeho ke sona se li khethollang.

Se etsang hore liphanele li fapane ke hore li lula li behiloe leboteng. Mokhoa o le mong feela oa ho fihlella liphanele ke ka pele.Bophahamo ba mapolanka bo tlase haholo ho feta switchboard le switchgear, 1200 Amp max. Li-panelboards li sebelisetsoa li-voltages ho fihlela ho 600 V. Har'a likarolo tse tharo tsa tsamaiso ea motlakase, li-panelboards li theko e tlaase le tse nyenyane ka ho fetisisa.

Lisebelisoa tsa Panelboards

Liphanele li fumaneha hangata libakeng tsa bolulo kapa tse nyane tsa khoebo moo tlhoko ea motlakase e seng holimo haholo. Lisebelisoa tse tloaelehileng tsa li-panels ke tsena:

• Meaho ea bolulo, ea khoebo, le litsi tsa liindasteri tse nyane. Malapeng le liofising, liphanele li tsamaisa motlakase likarolong tse fapaneng tsa moaho ho tloha phepelong e kholo. Ba ka tsamaisa motlakase litsing tsa HVAC, lisebelisoa tsa mabone, kapa lisebelisoa tse kholo tsa motlakase.
• Litsi tsa tlhokomelo ea bophelo. Litsing tsa tlhokomelo ea bophelo, li-panels li sebelisoa bakeng sa lits'ebetso tsohle tse boletsoeng ka holimo bakeng sa meaho ea bolulo le ea khoebo, hammoho le kabo ea matla a lisebelisoa tsa bongaka.

Ho ipapisitsoe le ts'ebeliso, liboto tsa liphanele li ka aroloa ka li-subtypes tse 'maloa, ho kenyeletsoa liboto tsa mabone le liphanele tsa kabo ea matla. Phanele e kholo, subpanel, le fusebox ke mefuta eohle ea liboto.

Likarolo tsa Panelboard

• Seqhenqha se seholo
• Sekoahelo sa potoloho
• Libaka tsa libese

Ke eng aSwitchboard?

Switchboard ke sesebelisoa se tsamaisang motlakase ho tloha mohloling o le mong kapa ho feta ho ea libakeng tse 'maloa tse nyenyane tsa tšebeliso. Ke kopano ea phanele e le 'ngoe kapa ho feta, e' ngoe le e 'ngoe e na le li-switches tse lumellang hore motlakase o tsamaisoe hape. Hobane ke kopano, switchboard e ka ntlafatsoa sebakeng sefe kapa sefe sa ts'ebeletso. Karolo ea bohlokoa ea li-switchboards ke hore hangata li kenyelletsa ts'ireletso ea overcurrent bakeng sa li-circuits tsa bona tsa phepelo mme li behiloe fatše. Likarolo tsa switchboard li reretsoe ho khutlisa matla.

Se khethollang li-switchboards ho tloha lits'ebetsong tse ling tsa motlakase tse hlalositsoeng ka tlase ke hore switchboard e emela kopano ea likarolo. Tekanyo ea motlakase ea li-switchboard system ke 600 V kapa ka tlase. Li-switchboards li fumaneha bakeng sa ts'ebeletso ho tloha ka pele le ka morao. Li-switchboards li khomarela litekanyetso tsa NEMA tsa PB-2 le UL standard -891. Li-switchboards li na le limithara tse bontšang boholo ba matla a fetang ho tsona, empa ha li na likarolo tsa tšireletso tse ikemetseng.

Likopo tsaLi-switchboards

Joalo ka mapolanka, li-switchboards li sebelisoa libakeng tsa khoebo le tsa bolulo, 'me, joalo ka switchgear, li sebelisoa litsing tsa indasteri. Li-switchboards li sebelisoa bakeng sa ho khutlisa lisebelisoa tsa mantlha tsa motlakase.

Li-switchboards li theko e boima ho feta li-panelboards empa li theko e tlaase ho feta switchgear. Sepheo sa li-switchboards ke ho aba matla pakeng tsa mehloli e fapaneng. Mefuta ea li-switchboards e kenyelletsa li-switchboards tsa sepheo se akaretsang le li-switchboards tsa fusible.

Likarolo tsa switchboard

• Liphanele le liforeimi
• Lisebelisoa tse sireletsang le ho laola
• Liphetoho
• Libaka tsa libese

Ke eng aSwitchgear?

Switchgear e kopanya li-switches, li-fuse kapa li-circuit breaker ho laola, ho sireletsa le ho arola lisebelisoa tsa motlakase.

Switchgear e fapane le li-switchboards le li-panelboards hobane e na le likarolo tse ikemetseng. Lisebelisoa tseo e leng likarolo tsa switchgear li sebelisoa ho bulela le ho tima motlakase.

Switchgear e sebelisetsoa ho fokotsa matla a lisebelisoa ho lumella mosebetsi hore o etsoe le ho hlakola liphoso ho ea tlaase. Ka kakaretso e sebelisoa litlhophisong moo phepelo e kholoanyane ea motlakase e hlokang ho aroloa har'a lisebelisoa tse ngata tse fapaneng, tseo ha e le hantle e leng litsamaiso tsa khoebo tsa li-voltage tse fapaneng (tse tlase, tse mahareng le tse phahameng). Switchgear e na le lisebelisoa tse netefatsang polokeho ea othomathike.

Switchgear ke eona e theko e phahameng ka ho fetisisa ebile e atile haholo ha e bapisoa le liboto tsa liphanele le li-switchboards. Tekanyo ea motlakase ea switchgear e fihla ho 38 kV, 'me tekanyo ea hona joale e fihla ho 6,000A. Switchgear e latela ANSI standard C37.20.1, UL standard 1558, le NEMA standard SG-5.

Qetellong, switchgear e ka sebelisoa ka ntle le ka tlung. Mefuta ea li-switchgear e kenyelletsa matla a tlase, a mahareng le a matla a phahameng.

Likopo tsaSwitchgear

Switchgear e sebelisoa haholo ho laola meroalo ea matla. Lisebelisoa tse tloaelehileng tsa switchgear li kenyelletsa:

• Lisebelisoa tsa matla le ho fetola, haholo-holo lisebelisoa tse ka sehloohong tsa ho aba (li-transformer, lijenereithara, marang-rang a matla, joalo-joalo).
• Ho tsebahatsa phoso ho potoloho ea motlakase le tšitiso e nakong pele ho tlala
• Taolo ea lisebelisoa lifemeng tsa motlakase le liteishene tsa jenereithara
• Taolo ea li-transformer lits'ebetsong tsa phepelo ea lisebelisoa
• Tšireletso ea mehaho e meholo ea khoebo le litsi tsa data

Likaroloana tsaSwitchgear

• Draw-out breakers: ho sebelisa li-draw-out breakers tse nang le switchgear ho thibela ho koala sistimi ea motlakase bakeng sa tlhokomelo.
• Lisebelisoa tsa ho fetola matla: li-circuit breakers, fuses, joalo-joalo Likarolo tsena li reretsoe ho senya matla a potoloho.
• Likarolo tsa taolo ea matla: liphanele tsa taolo, li-transformer, li-relay tse sireletsang. Likarolo tsena li reretsoe ho laola matla.
