Bal aynu eegno sida xisaabinta hadda lagu sameeyo awoodda

Ka hor inta Socota in design ah ee korontada gurigaaga, waa in aad nidaamka lacag bixinta la muujinaysa ah ugu rarataan culaysyo la filayo on goobta iyo dhererka qaybaha gaarka ah ee cable ee a. Si loo ururiyo nidaamka noocan oo kale ah iyo baahida loo qabo in loo xisaabiyo ah "awood" ee hadda. Uruurinta saxda ah guriga korontada safaree qaybaha lagama maarmaanka ah ee fiilooyinka in fiilooyinka ka kululaado ilaalin doona iyo, sida, waxaa macquul ah dabka. Aan aragno, laakiin waa wixii xisaab ah "awood" ee hadda.

doorashada saxda ah ee qalabka bedesheen iyo cable cross-qaybta ay ku xiran tahay qiimaha kala duwan ee xuduudaha ka shabakadaha korontada. The ugu iyaga ka mid ah oo muhiim ah waa hadda korontada. Oo marxalad ee la dhigaayo qiimaha kaliya la go'aamin karaa by xisaabinta xisaabeed. Aad muhiim u ah waxaa loo arkaa "xoog" ah xisaabinta ee hadda ka jirta shabakadaha saddex waji, halkaas oo load waa in ka mid ah wejiyada loo bandhigi siman, si looga fogaado in dhabtii. Si kastaba ha ahaatee, in shabakadaha la deggan magaalooyinka, xisaabinta waa in la fuliyaa ee design ee ma aha oo kaliya gaashaankii, laakiin sidoo kale la deggan yahay.

"Power" xisaabinta hadda waxaa la siiyaa awood qiimaha loo yaqaan koronto, nooca xamuulka iyo danab sahayda. Waayo, dhaxe-hal waji oo isticmaalaya formula soo socda: Waxaan = P / (U × cosφ), halkaas oo:

• U - qiimaha danab dhabta ah waxaa lagu cabiraa volts;
• cosφ - dhiganta factor awood.

Iyada oo ku xidhan nooca factor awood load la soo xulay. Sidaa darteed, load firfircoon (xubno kululeeyaha, iyo laambadahoodii yaryaraa incandescent) waa qiyaastii u siman yihiin in midnimo. Si kastaba ha ahaatee, marka aad u aragto in ee Xamuulka resistive mar walba qayb ka Waxyeelo, ka dibna xisaabinta waa wax caadi ah in la isticmaalo qiimaha sababtoo ah, loo siman yahay 0,95. Marka xisaabinta load ah, taas oo ah waxa lagu gartaa sare xoog Waxyeelo (Margado nalalka, matoorrada korontada, foornada induction, gudbiyeyaasha alxanka , iwm) cosφ qiimaha celceliska Qaaday, loo siman yahay 0.8.

Waayo, formula-waji korontada AC yeelan doontaa foomka soo socda: Waxaan = P / (1,73 x U × cosφ).

Waayo, factor shabakadaha awood saddex waji for xamuulka firfircoon oo Waxyeelo si buuxda u yihiin shabakadaha-hal waji isku mid.

Sayidka, iyadoo la isticmaalayo qaaciidooyinka kor ku xusan waa loo baahan yahay si ay u qabtaan xisaabaha oo dhan ugu rarataan culaysyo xoogga qiimaha hadda korontada, in la isticmaalo goobta gaar ah.

Marxaladda xigta ee xisaabinta our, noqon doona doorashada iskutallaabta cable qaybta. Inkastoo suugaanta farsamo ee inta badan ka heli kartaa wax caynkaas ah sida "cable awoodda xisaabinta", dhab ahaantii, waxa aan la xisaabinayaa, laakiin weli "doorasho". Under fahmi formula xisaabinta ee go'aaminta load a hadda kor ku xusan. In joogitaanka qiimaha qaar ka mid ah hadda iyo danab cable qaybta cross waxaa ka miisaska eegno-up ee la doortay. miisaska Kuwani waa mid aad u muuqaal ah oo aan u baahnayn sharaxaad faahfaahsan. Marka hore waxaad dooranaysaa wax silig: copper ama aluminium, ka dibna danab sahayda iyo qiimaha hadda waxaa lagu go'aamiyaa ka cable cross-qaybta.

Halkan, run ahaantii, waxaan eegay sida loo xisaabiyo load korontada iyo cross-qaybta la doortay ee fiilooyinka mashaariicda electrification.
