Guud ahaan, jidhka bini'aadamka wuxuu dareemi karaa qiimaha hadda ee kicinta waa qiyaastii 1 mA.Marka jidhka bini'aadamku dhaafo 5 ~ 20mA, murqaha ayaa isku laabanaya oo gariiraya, si aan qofka loo kala saari karin siliga.Wax soo saarka shoogga korantada hadda iyo waqtiga ay ogol yihiin wadamadu waa 30mA*S iska caabbinta jidhka bini'aadamka Sida caadiga ah 1500 ohms ~ 300000 ohms, qiimaha caadiga ah waa 1000 ohms ~ 5000 ohms, qiimaha lagu taliyey waa 1500 ohms
Qiimaha tamarta badbaadada leh waxaa laga heli karaa falcelinta jidhka bini'aadamka ee hadda iyo iska caabinta jidhka bini'aadamka: qiimaha badbaadada ee waddankeena guud ahaan waa 12 ~ 50V
U adkeyso danab, qulqulka hadda socda iyo badbaadada shaandhada awoodda EMI:
Cadaadiska iyo badbaadada
1. Haddii capacitor-ka Cx ee shaandhada ku jira uu jabo, waxay u dhigantaa wareegga gaaban ee grid AC, ugu yaraan keenaysa in qalabku joojiyo shaqada;haddii capacitor-ka Cy uu jabo
Waxay u dhigantaa in lagu daro korantada korantada AC ee daboolka qalabka, taas oo si toos ah u khatar gelinaysa badbaadada shakhsi ahaaneed waxayna saameyneysaa dhammaan qalabka biraha birta ah sida dhulka tixraaca.
Badbaadada wareegga ama qalabka, badanaa waxay horseedaa gubashada wareegyada ama qalabka qaarkood.
2. Qaar ka mid ah heerarka badbaadada cadaadiska u adkaysta caalamiga ah waa sida soo socota:
Jarmalka VDE0565.2 Tijaabada Korantada Sare (AC) P, N ilaa E 1.5kV/50Hz 1 daqiiqo
Switzerland SEV1055 Tijaabada Korantada Sare (AC) P, N ilaa E 2*Un+1.5kV/50Hz 1 daqiiqo
US UL1283 Tijaabada Korantada Sare (AC) P, N ilaa E 1.0kV/60Hz 1 daqiiqo
Jarmalka VDE0565.2 Tijaabada Korantada Sare (DC) P ilaa N 4.3*Un 1 daqiiqo
Switzerland SEV1055 Tijaabada Korantada Sare (DC) P ilaa N 4.3*Un 1 daqiiqo
US UL1283 Tijaabada Korantada Sare (DC) P ilaa N 1.414kV 1 daqiiqo
tusaale:
(1) Sababta loo isticmaalo danabka DC ee tijaabada korantada PN waa in awoodda Cx ay weyn tahay.Haddii tijaabada AC la isticmaalo, awoodda hadda loo baahan yahay tijaabiyaha korantada
Waa mid aad u weyn, taasoo keentay mug weyn iyo qiimo sare;dhibaatadani ma jirto marka DC la isticmaalo.Laakin si loogu badalo danabka shaqada AC mid u dhigma danab shaqeeya
Tusaale ahaan, tamarta ugu badan ee AC ee shaqaynaysa waa 250V(AC)=250*2*1.414=707V(DC),sidaa daraadeed qeexida badbaadada UL1283 waa
1414V(DC)=707*2.
(2) Shuruudaha tijaabada korantada ee adkeysiga ee buug-gacmeedka warshadda xirfadleyda shaandhada caanka ah ee caalamiga ah:
Corcom Corporation (USA) P, N ilaa E: 2250V(DC) hal daqiiqo P ilaa N: 1450V(DC) hal daqiiqo
Schaffner (Switzerland) P, N ilaa E: 2000V(DC) hal daqiiqo P ilaa N: Marka laga reebo
Soosaarayaasha xirfadleyda shaandheynta gudaha guud ahaan waxay tixraacaan xeerarka badbaadada VDE ee Jarmalka ama xeerarka badbaadada UL ee Mareykanka
Daadaynta hadda iyo badbaadada
Kapacitor-ka caadiga ah ee Cy ee wareegga shaandhada caadiga ah waxa uu leeyahay hal dhammaad oo lagu dhammeeyo kiis bir ah.Marka laga eego aragtida qaybta korantada, daboolka birta ee shaandhada ayaa leh
1/2 ee korantada la qiimeeyay, markaa marka laga eego aragtida badbaadada, qulqulka hadda jira (dhaqashada hadda) ee shaandhada ilaa dhulka iyada oo loo marayo Cy waa in ay ahaataa mid yar intii suurtagal ah.
waxay khatar gelinaysaa badbaadada shakhsi ahaaneed.
Xeerarka badbaadada ee qulqulka hadda ka jira qaar ka mid ah waddamada warshadaha waaweyn ee adduunka waa sida soo socota:
Fiiro gaar ah: 1. Daaqadda hadda jirta waxay si toos ah ula siman tahay tamarta korantada iyo inta jeer ee xadhkaha.Daadaynta hadda ee shaandhada 400Hz grid waa 8 jeer ka badan 50Hz (sida.
Shaandheeyayaasha la kulma xeerarka badbaadada ee xadhkaha korantada ee soo noqnoqda korantada waxa laga yaabaa inaanay la kulmin xeerarka badbaadada ee xadhkaha korantada ee soo noqnoqda)
2. Marka la hubinayo qulqulka dareeraha ee shaandhada, wareegga cabbiraadda ee waafaqsan heerarka caalamiga ah waa in la isticmaalaa (sida sawirka hoose ka muuqata).Marka la cabbirayo, kiis bir ah ma awoodo
Iyadoo salka ku haysa, waa in la hakiyo.
