I. Fikradaha aasaasiga ah ee sanduuqyada qaybinta
Sanduuqa qaybinta waa aalad udub dhexaad u ah nidaamka korantada ee loo isticmaalo qaybinta dhexe ee tamarta korantada, xakamaynta wareegyada iyo ilaalinta qalabka korantada. Waxay u qaybisaa tamarta korantada ilaha korantada (sida transformers) aaladaha korantada ee kala duwan waxayna isku daraa hawlaha ilaalinta sida culeyska xad dhaafka ah, wareegga gaaban iyo daadinta.

Isticmaalka ugu muhiimsan:

Qaybinta iyo xakamaynta tamarta korantada (sida tamarta laydhka iyo qalabka korontada).

Ilaalinta wareegga ( culeyska xad dhaafka ah, wareegga gaaban, daadinta).

La soco heerka wareegga (voltage iyo bandhigay hadda).

Ii. Kala soocidda sanduuqyada qaybinta
Marka la eego xaaladaha codsiga:

Sanduuqa qaybinta guriga: Xajmi yar, oo leh heer ilaalineed oo hooseeya, isku darka ilaalinta daadinta, furayaasha hawada, iwm.

Sanduuqa qaybinta warshadaha: Awood weyn, heer ilaalin sare ah (IP54 ama ka sareeya), taageeraya xakamaynta wareegga adag.

Sanduuqa qaybinta bannaanka: Biyo-ilaalinta iyo boodhka (IP65 ama wixii ka sareeya), oo ku habboon jawiyada hawada furan.

Habka rakibaadda:

Nooca rakibaadda bannaanka ah: Si toos ah loogu dhejiyay gidaarka, fududahay in la rakibo.

Nooca qarsoodiga ah: Ku dheji gidaarka, waa mid qurux badan laakiin dhismuhu waa mid adag.

Qaab dhismeed ahaan:

Nooca go'an: Qaybaha waxaa lagu rakibay hab go'an, oo leh qiime jaban.

Nooca Drawer (sanduuqa qaybinta modular): Naqshad qaabaysan, oo ku habboon dayactirka iyo ballaarinta.

Iii. Qaab-dhismeedka Sanduuqa Qaybinta
Jirka sanduuqa:

Qalab: Bir (saxan bir ah oo qabow-duuban, bir aan lahayn) ama bir aan ahayn (cag Injineer ah).

Heerka ilaalinta: Koodadka IP (sida IP30, IP65) waxay muujinayaan awoodaha boodhka iyo biyaha.

Qaybaha korantada ee gudaha:

Jabiyayaasha wareegga: ilaalinta xad-dhaafka ah/wareegga gaaban (sida furayaasha hawada, jebiyeyaasha kiis la qaabeeyey).

Xidhiidhiyaha: Gacan ku jar korontada

Aaladda ilaalinta daadinta (RCD): Waxay ogaataa daadinta hadda iyo safarrada.

Mitirka korontada: Cabbirka tamarta korontada.

Xiriiriyaha: Wuxuu si fog u koontaroolaa daarta iyo daminta wareegga.

Ilaalinta Surge (SPD): Waxay ka ilaalisaa hillaaca ku dhaca ama korontada.

Qaybaha caawimada:

Basbarrada (buska naxaasta ama aluminiumka), baloogyada terminaalka, nalalka tilmaame, marawaxadaha qaboojinta, iwm.

Iv. Qiyaasaha Farsamada ee sanduuqa qaybinta
Hadda la qiimeeyay: sida 63A, 100A, 250A, kaas oo lagu dooranayo iyadoo lagu salaynayo wadarta awooda culayska.

Danab la qiimeeyay: Caadi ahaan 220V (hal-waji) ama 380V (saddex waji).

Heerka ilaalinta (IP): sida IP30 (boodhka-ka-ilaalinta), IP65 (biyo-ilaalinta).

Adkeysiga wareegga-gaaban: Waqtiga aad u adkeysan karto wareegga gaaban ee hadda jira (sida 10kA/1s).

Awoodda jebintu: Ciladda ugu badan ee hadda jirta ee jabiyaha wareegga uu si badbaado leh u goyn karo.

V. Hagaha Xulashada Sanaaduuqda Qaybinta
Marka loo eego nooca rarka:

Wareegga iftiiminta: Dooro 10-16A wareegga wareegga yar (MCB).

Qalabka baabuurta: Kuleyliyaha kuleyliyaha ama matoorrada wareegga wareegga ee gaarka ah ayaa u baahan in la is waafajiyo.

Aagagga xasaasiga sare leh (sida musqulaha) : waa in la rakibaa aaladda ilaalinta daadinta (30mA).

Xisaabinta awoodda

Wadarta hadda waa ≤ wakhtiga la qiimeeyay ee sanduuqa qaybinta × 0.8 (margin nabdoonaanta).

Tusaale ahaan, wadarta guud ee awoodda culaysku waa 20kW (saddex weji), ta hadda jirtana waa qiyaastii 30A. Waxaa lagu talinayaa in la doorto sanduuqa qaybinta 50A.

La qabsiga deegaanka

Deegaanka qoyaanka leh: Dooro sanduuqa jirka ee birta ah + heerka ilaalinta sare (IP65).

Bey'ad kuleyl sare leh: godadka kuleylka kuleylka ama marawaxadaha ayaa loo baahan yahay.

Shuruudaha la kordhiyay:

Kaydi 20% booska banaan si loo fududeeyo ku darida wareegyada cusub hadhow.

Vi. Taxadirka Rakibaadda iyo Dayactirka
Shuruudaha rakibidda:

Meeshu waa mid qallalan oo hawo wanaagsan leh, kana fog alaabta gubanaysa.

Sanduuqa si la isku halleyn karo ayaa loo dejiyay si looga hortago khatarta korontadu.

Tilmaamaha midabka fiilada (silig nool casaan/jaalle/cagaar, buluug silig dhexdhexaad ah, silig dhulka cagaaran huruud ah).

Qodobbada muhiimka ah ee dayactirka:

Si joogto ah u hubi in xadhiggu dabacsan yahay ama oksaydhaysan yahay.

Nadiifi boodhka (si aad uga fogaato wareegyada gaaban).

Tijaabi qalabka ilaalinta (sida adigoo riixaya badhanka tijaabada ilaalinta daadinta bishiiba mar).

Vii. Dhibaatooyinka iyo Xalka Caadiga ah
Socdaal joogto ah

Sababta: culeys xad dhaaf ah, wareegga gaaban ama daadinta.

Xallinta dhibaatada: Ka saar xariiqda culeyska adigoo isticmaalaya khadka oo hel wareegga khaldan.

Goosashada aaladda ka hortagga daadinta

Macquul ah: Daboolida wareegga oo burburay, korontadii ka soo daatay qalabka.

Daaweynta: Isticmaal megohmmeter si aad u tijaabiso caabbinta dahaarka.

Sanduuqa aad buu u kululaaday.

Sababta: culeys xad dhaaf ah ama xiriir xumo.

Xalka: Iska yaree culeyska ama adkee xirmooyinka terminalka.

Viii. Xeerarka Badbaadada
Waa in ay u hoggaansamaan heerarka qaranka (sida GB 7251.1-2013 "Kuwa danab-yar ee Bedelashada Assemblies").

Marka la rakibayo oo la dayactirayo, korontadu waa in la gooyaa, hawlgalkana waa in ay fuliyaan khabiiro koronto.

Waa mamnuuc in la beddelo wareegyada gudaha sida la rabo ama laga saaro aaladaha ilaalinta.
