Xakamaynta wareegtada: wuu shidi karaa, qaadi karaa oo jebin karaa wakhtiga ku jira xaaladaha wareegga caadiga ah, waxa kale oo lagu shidi karaa xaalado wareeg oo aan caadi ahayn oo cayiman, waxa uu qaadi karaa wakhti go'an oo uu jebiya hadda dareemaha mishiinka.
Mikro Circuit Breaker, oo loo yaqaan MCB (Micro Circuit Breaker), waa qalabka korantada ee ugu badan ee loo isticmaalo ilaalinta terminalka marka lagu dhisayo aaladaha qaybinta qaybinta korantada.Waxaa loo isticmaalaa wareegga gaaban ee hal-waji iyo saddex-weji gaaban, culeys xad-dhaaf ah iyo ilaalinta korantada oo ka hooseeya 125A, oo ay ku jiraan afar nooc oo hal cidhif ah 1P, laba-cir 2P, saddex-cir 3P iyo afar-tiir 4P.
Xakamaynta wareegga yar waxa uu ka kooban yahay habka hawlgalka, xidhiidhka, qalabka ilaalinta (qalabka sii daynta ee kala duwan), nidaamka daminta arc, iwmKa dib marka xidhiidhka ugu muhiimsani xiro, habka safarka bilaashka ah wuxuu xiraa xiriirka ugu muhiimsan ee booska xiritaanka.Gariiradda sii daynta xad-dhaafka ah iyo walxaha kulaylka ee sii-deynta kulaylka waxay ku xiran yihiin wareegga ugu muhiimsan ee taxanaha, iyo gariiradda sii-deynta korantada waxay ku xiran tahay korontadu si siman.Marka wareeggu dhaco wareeg gaaban ama culeys culus oo culus, cufan ee qalabka safarka ee dheeraadka ah ayaa soo jiidanaya, samaynta habka safarka bilaashka ah ee shaqeeya, xiriirka ugu muhiimsana wuxuu gooyaa wareegga ugu muhiimsan.Marka wareeggu buux dhaafiyo, qaybta kulaylka ee qalabka safarka kulaylka ayaa kululaanaya si uu u leexiyo xaashida bimetal oo riix habka safarka bilaashka ah si uu u dhaqmo.Marka wareeggu ku hoos jiro korantada, waxaa la sii daayaa armature-ka soo-saaraha ka hooseeya.Sidoo kale waxay ogolaataa habka safarka bilaashka ah inuu shaqeeyo.
Xakamaynta wareegtada hadda jirta: Shidaal si toos ah u shaqeeya marka hadhaaga wareegga wareegga uu ka sarreeyo qiimaha hore loo dejiyay.Xakamaynta wareegga wareegga ee sida caadiga ah loo isticmaalo waxaa loo qaybiyaa laba qaybood: nooca Voltage iyo nooca hadda, iyo nooca hadda waxa loo qaybiyaa nooca elektromagnetic iyo nooca elektarooniga ah.Xakamaynta wareegga wareegga wareegga waxaa loo isticmaalaa si looga hortago shoogga shakhsi ahaaneed, waana in lagu doortaa iyadoo loo eegayo shuruudaha kala duwan ee xiriirka tooska ah iyo ilaalinta xiriirka dadban.
Dooro iyadoo loo eegayo ujeedada isticmaalka iyo meesha uu yaal qalabka korontadu
1) Ka ilaalinta taabashada tooska ah ee korontadu
Sababtoo ah waxyeelada xiriirka tooska ah ee shoogga korantada waa mid aad u weyn, cawaaqibta ayaa ah mid halis ah, sidaas darteed si aad u doorato wareegga wareegga qulqulka leh dareenka sare, qalabka korontada, qalabka korantada ee moobiilka iyo khadadka ku-meel-gaarka ah, waa in lagu rakibaa wareegga hadda shaqeeya ee 30mA, wakhtiga shaqada gudahooda 0.1s wareegtada dareerahaGuryaha la dego ee leh qalab guri oo badan, waxa fiican in la rakibo ka dib markaad gasho mitirka tamarta guriga.
Haddii mar ay shoog koronto fudud keento dhaawac labaad (sida ka shaqaynta joogga), waa in lagu rakibaa wareegtada wareegga wareegga oo hadda shaqaynaysa 15mA iyo wakhtiga hawlgalka gudaha Maraykanka.Qalabka caafimaadka korantada ee isbitaalada, waa in lagu rakibaa furayaasha wareegga wareegga oo leh 6mA iyo waqtiga hawlgalka gudaha Mareykanka.
2) Ilaalinta xiriirka dadban
Shoogga korantada ee sida tooska ah loo taabto meelo kala duwan waxay qofka u keeni kartaa heerar kala duwan oo waxyeello ah, sidaas awgeed waa in meelo kala duwan lagu rakibaa wareegyada wareegyada qulqulaya.Waxaa loo baahan yahay in la isticmaalo biriyeyaasha wareegga wareegga dareeraha oo leh dareen sare oo loogu talagalay meelaha shoogga korontadu uu ka dhib badan yahay.Meelaha qoyan marka loo eego meelaha engegan khatarta shoogga korontadu aad bay uga weyn tahay, guud ahaan waa in lagu rakibaa hadda shaqaynaysa 15-30mA, wakhtiga shaqaynaysa 0.1sQalabka korantada ee biyaha, ficil waa in lagu rakibaa.Xakamaynta wareegga wareegga oo leh 6-l0mA hadda iyo wakhtiga hawlgalka gudaha US.Qalab koronto oo ay tahay in hawlwadeenku uu ku istaago shay bir ah ama weel bir ah, waa in lagu rakibaa korantadu ka sarreyso 24V, waa in lagu rakibaa fiilo wareeg ah oo hadda shaqaynaysa oo ka hooseysa 15mA iyo wakhtiga hawlgalka gudaha Maraykanka.Qalabka korantada ee go'an ee leh korantada 220V ama 380V, marka iska caabbinta dhulka ee guryuhu ay ka hooseeyaan 500fZ, hal mashiin ayaa ku rakibi kara jebinta wareegga wareegga oo leh hadda shaqeynaya 30mA iyo waqtiga hawlgalka ee 0.19.Qalab koronto oo waaweyn oo hadda lagu qiimeeyay in ka badan 100A ama wareegga korantada oo leh qalab koronto oo badan, waxaa lagu rakibi karaa furaha wareegga wareegga oo hadda shaqeynaya 50-100mA.Marka caabbinta dhulka ee qalabka korantada ay ka hooseyso 1000, waxaa lagu rakibi karaa fiilo wareeg ah oo hadda shaqaynaysa 200-500mA.
