Tijaabada Iska caabinta Dhulka

Erayga "iska caabin dhulka" waa kelmad si liidata loo qeexay.Heerarka qaar (sida heerarka badbaadada ee qalabka guriga), waxa ay tilmaamaysaa iska caabbinta dhulka ee gudaha qalabka, halka heerarka qaarkood (sida koodhka naqshadaynta dhulka), waxa ay tilmaamaysaa iska caabbinta dhammaan qalabka dhulka.Waxa aan ka hadleyno waxaa loola jeedaa caabbinta dhulka ee gudaha qalabka, taas oo ah, caabbinta dhulka (sidoo kale loo yaqaan caabbinta dhulka) ee heerarka badbaadada alaabta guud, taas oo ka tarjumaysa qaybaha daboolan ee qalabka iyo guud ahaan dhulka qalabka.iska caabin u dhexeeya terminal.Halbeegga guud wuxuu dhigayaa in iska caabbintani aysan ka badnayn 0.1.

Iska caabinta dhulka waxay ka dhigan tahay marka dahaarka qalabka korontadu uu guuldareysto, qaybaha birta ah ee si fudud loo heli karo sida korantada korantada ayaa laga yaabaa in lagu dallaco, waxaana loo baahan yahay ilaalin la isku halleyn karo oo loogu talagalay badbaadada isticmaalaha qalabka korontada.Iska caabinta dhulka ayaa ah tilmaame muhiim ah oo lagu cabbirayo isku halaynta ilaalinta dhulka korantada.

Iska caabbinta dhulka waxaa lagu qiyaasi karaa tijaabiye iska caabbinta dhulka.Maadaama caabbinta dhulku aad u yar tahay, badanaaba tobanaan milliohms, waxaa lagama maarmaan ah in la isticmaalo cabbirka afar-terminal si loo baabi'iyo caabbinta xiriirka oo loo helo natiijooyinka cabbirka saxda ah.Tijaabada iska caabinta dhulka waxa ay ka kooban tahay sahayda awooda tijaabada ah, wareegga tijaabada, tilmaame iyo wareegta alaarmiga.Korontada tijaabadu waxay soo saartaa tijaabada AC ee hadda ah 25A (ama 10A), wareegga imtixaanku wuxuu kordhiyaa oo beddelaa signalka korantada ee uu helay aaladda tijaabada ku jirta, kaas oo uu soo bandhigay tusaha.Haddii caabbinta dhulka la qiyaasay uu ka weyn yahay qiimaha alaarmiga (0.1 ama 0.2), qalabku wuxuu dhawaaqi doonaa alaarmiga iftiinka.

Cabbiraadda tijaabada iska caabinta dhulka ee uu maamulo barnaamijku

Marka tijaabiyaha iska caabbinta dhulka ee uu gacanta ku hayo uu cabbiro caabbinta dhulka, clip-ka tijaabada ah waa in lagu dhejiyaa barta isku xirka dusha sare ee qaybta la heli karo.Waqtiga imtixaanku ma fududa inuu aad u dheeraado, si aanu u gubin sahayda tijaabada.

Si sax ah loo cabbiro caabbinta dhulka, labada fiilood ee khafiifka ah (filliyada sambalka korantada) ee ku yaal clip-ka tijaabada ah waa in laga saaraa terminalka korantada ee aaladda, lagu beddelo laba fiilooyin oo kale, oo lagu xidho barta xidhiidhka ka dhexeeya shayga la cabbiray iyo kan hadda jira. Tijaabi clip si aad si buuxda u baabi'iso saamaynta caabbinta xidhiidhka ee imtixaanka.

Intaa waxaa dheer, tijaabiyaha iska caabbinta dhulka ayaa sidoo kale cabbiri kara caabbinta xiriirka ee xiriirada korantada ee kala duwan (xiriirada) marka lagu daro cabbiraadda caabbinta dhulka.

Tijaabada iska caabbinta Dhulka ee Barnaamijyada ee Merrick Instruments RK9930Imtixaanka ugu badan ee hadda jira waa 30A;RK9930AImtixaanka ugu badan ee hadda jira waa 40A;RK9930BHadda wax soo saarka ugu badan waa 60A; Waayo, imtixaanka iska caabin grounding, hoos qulqulo kala duwan, xadka sare ee iska caabin imtixaanka waxaa loo xisaabiyaa sida soo socota:

Marka iska caabbinta la xisaabiyay R ay ka weyn tahay qiimaha iska caabinta ugu badan ee tijaabiyaha, qaado qiimaha iska caabinta ugu badan.

Waa maxay faa'iidooyinka tijaabiyaha iska caabbinta dhulka ee uu maamulo barnaamijka?

Tijaabada iska caabbinta Dhulka ee Programmable Earth-ka-dhaliyaha mawjadda sine waxaa inta badan gacanta ku haya CPU si ay u dhaliso mawjadda halbeegga ah ee sinaha, iyo qalloocintiisa qaab mawjadda ayaa ka yar 0.5%.Mawjadda sinjiga caadiga ah waxaa loo diraa wareegga korantada korantada si loo kordhiyo awoodda, ka dibna hadda waxaa soo saaraya beddelka wax soo saarka hadda.Hadda wax-soo-saarku waxa uu maraa transformer-ka hadda jira.Saamaynta, hagaajinta, shaandhaynta, iyo beddelka A/D waxa loo diraa CPU si loo soo bandhigo.Samaynta korantada, hagaajinta, shaandhaynta, iyo beddelka A/D waxa loo diraa CPU, qiimaha iska caabbinta la qiyaasay waxa xisaabiya CPU-gu.

Tijaabada Iska caabbinta Dhulka ProgrammableMarka la barbar dhigo nooca caadiga ah ee xakamaynta tamarta korantada tijaabada caabbinta dhulka, waxay leedahay faa'iidooyinka soo socda:

1. Wax soo saarka isha joogtada ah;u dhig wakhtiga xaadirka ah 25A, gudaha tirada tijaabada ee tijaabiyeyaashan taxanaha ah, inta lagu jiro tijaabada, wax soo saarka hadda ee tijaabiyaha waa 25A;hadda wax-soo-saarku kuma beddelo culayska.

2. Soo-saarka hadda ee barnaamijka-xakamaynta tijaabiyaha iska caabbinta dhulka ma saameynayso tamarta korontada.Nidaamiyaha korantada ee dhaqameed nooca tijaabiyaha iska caabinta dhulka, haddii korontadu is bedbeddesho, hadda wax soo saarkeeda ayaa la bedbeddeli doona;Shaqadan tijaabiyaha iska caabbinta dhulka ee uu maamulo barnaamijka laguma guulaysan karo maareeyaha korantada ee nooca caabbinta dhulka.

3.Tijaabada iska caabinta dhulka ee RK7305waxa uu leeyahay shaqo habayn software;haddii wax soo saarka hadda, muujinta caabbinta hadda iyo tijaabada tijaabada ee tijaabiyaha ay dhaafto xadka lagu sheegay buug-gacmeedka, markaas isticmaaluhu wuxuu qiyaasi karaa tijaabiyaha iyadoo loo eegayo tallaabooyinka hawlgalka ee buug-gacmeedka.Taxanaha RK9930Si toos ah ayaa loo cabbiri karaa mana saameynayso bay'addu

4.The soo-saarka soo noqnoqda hadda waa variable;RK9930,RK9930A,RK9930BSoosaarka hadda ee tijaabiyaha iska caabbinta dhulka ayaa leh laba jeer oo la kala dooran karo: 50Hz/60Hz, kaas oo buuxin kara baahiyaha qaybaha kala duwan ee tijaabada.

Tijaabinta waxqabadka badbaadada ee qalabka guriga

1. Tijaabada caabbinta dahaarka

Iska caabbinta dahaarka ee qalabka korontada guriga waa mid ka mid ah calaamadaha muhiimka ah ee lagu qiimeeyo tayada dahaarkooda.Caabbinta dahaarka waxaa loola jeedaa iska caabbinta u dhaxaysa qaybta nool ee qalabka guriga iyo qaybta birta ah ee aan noolayn.Iyada oo horumarka degdega ah ee warshadaha qalabka guriga iyo korodhka weyn ee caanka ah ee alaabta noocaas ah, si loo hubiyo badbaadada shakhsi ahaaneed ee dadka isticmaala, shuruudaha tayada ilaalinta ee qalabka guriga ayaa noqda mid aad u adag.

Habka hawlgalka qalabka cabbiraadda caabbinta dahaarka

1. Ku xidh qalabka korantada, shid furaha korantada, nalka tilmaame koronto ayaa shid;

2. Dooro danabka shaqada oo riix batoonka loo baahan yahay;

3. Dooro qiimaha alaarmiga;

4. Dooro wakhtiga tijaabada (ee taxanaha bandhiga dhijitaalka ah, nooca tilmaamuhu ma laha shaqadan);

5. Dugsi la'aanta ();(Taxane RK2681 ayaa taageeri kara)

6. Si aad u cabbirto cabbirka buuxa, ku xidh iska caabiyaha cabbirka ee ku dheggan dhammaadka cabbiraadda, oo habee cabbirka cabbirka cabbirka oo dhan si uu tilmaamuhu u tilmaamo cabbir buuxa.

7. Ku xidh shayga la qiyaasay ilaa dhamaadka cabbirka oo akhri caabbinta dahaarka.

Tijaabada iska caabbinta dahaarka taxaddarrada tijaabada

1. Waa in si buuxda loo diiriyaa ka hor inta aan la cabbirin si looga saaro qoyaanka mashiinka, gaar ahaan cimilada qoyan ee xilli-roobaadka ee koonfurta.

2. Marka la cabbirayo caabbinta dahaarka ee qalabka korantada ee shaqaynaya, waa in marka hore qalabka laga saaraa meesha uu ku socdo, cabbirkana waa in si degdeg ah loo sameeyaa ka hor inta aanu qalabka kuleylku hoos ugu dhicin heerkulka qolka si looga hortago in qiimaha la qiyaasay uu saameeyo Uumiga oogada dahaadhka ah.

3. Waa in qalabka wax lagu cabbiraa uu ahaadaa mid aan shaqaynayn, qalabkuna waa in uu ahaadaa mid shidan si loo cabbiro caabbinta dahaadhka, iyo wareegyada ama qaybaha aan la xidhiidhin qaybta la tijaabiyey waa in la gooyaa inta lagu jiro cabbirka. .

4. Si looga fogaado qiyamka cabbiraadda ee ay saamayso dahaadhka liita ee fiilada isku xidha cabbirka, dahaadhka fiilada ku xidhan waa in si joogto ah loo hubiyaa oo aan la isku qalloocin.
