Macluumaadka aasaasiga ah ee isticmaalayaasha
Warshada alxanka leh ayaa inta badan soo saarta shabagyo alxan oo kala duwan, shabaqyada xayndaabka, shabaqyada cawska, shabaqyada, shabaqyada, shabaqyada barbecue, qafisyada bakaylaha, iwm 1000 kVA iyo 1630 kVA transformers.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Awoodda guud ee mishiinka alxanka ee leh 1000KVA transformer waa 1860KVA, celceliska awoodda korantadu waa PF = 0.7, isbeddelka shaqadu hadda waa 1050-2700A.Awoodda guud ee mishiinka alxanka ee leh 630KVA Transformer waa 930KVA, celceliska awoodda korontada waa PF = 0.7, iyo isbeddelka shaqada ee hadda jira waa 570-1420A.
Falanqaynta Xaaladda Nidaamka Awoodda
Qalabka korantada alxanka ayaa inta badan loo isticmaalaa in lagu dejiyo culeyska weyn ee hadda jira, kaas oo ah culeys aan toos ahayn.Qalabku wuxuu soo saaraa tiro badan oo harmonics inta lagu jiro hawlgalka.Isku-dhafka hadda jira ee ka tirsan isha is-waafajinta ee caadiga ah ayaa lagu duraa korantada korantada, iyo xannibaadda korantadu waxay dhalisaa danab iswada leh, taasoo keenaysa korantada korantada iyo hadda Qalloocintu waxay saamaysaa tayada sahayda korantada iyo badbaadada hawlgalka, waxay kordhisaa luminta khadka iyo dhimista danabka, waxayna kordhisaa awoodda.Sidaa darteed, waa lagama maarmaan in la doorto software-ka habaysan ee leh xakamaynta iswaafajinta si loo xakameeyo harmonics, magdhowga culeyska falcelinta, iyo hagaajinta qodobka awoodda.
Shaandhayso qorshaha daaweynta magdhowga awooda falcelinta
Yoolalka dowladnimada
Naqshadeynta qalabka magdhawga filtarku waxa uu buuxiyaa shuruudaha xakamaynta iswaafajinta iyo maaraynta awooda falcelinta.
Marka la eego habka 0.4KV ee habka hawlgalka, ka dib marka la geliyo qalabka magdhowga shaandhada, garaaca garaaca wadnaha ayaa la xakameynayaa, celceliska tamarta bishiiba waa 0.92.
Dhawaaqa is-waafajinta ee nidaamka sare leh, kororka dhawaaqa, iyo qulqulka xad dhaafka ah ee ay sababto isku xidhka wareegga laanta magdhowga filter ma dhici doonto.

Fikradaha naqshadeynta
Iyada oo ku saleysan xaaladda dhabta ah ee shirkadda, shirkaddu waxay si buuxda u tixgalinaysaa qodobka awoodda culeyska iyo xakamaynta iswaafajinta ee shaandhada magdhowga tamarta falcelinta ee mishiinka alxanka, waxayna ku rakibtaa aaladda magdhowga tamarta falcelinta shaandhada dhinaca 0.4KV dhinaca korantada hoose ee shirkadda. Transformer si loo xakameeyo harmonics oo loo magdhabo awoodda falcelinta si loo hagaajiyo qodobka awoodda.
Inta lagu jiro habka shaqada ee mashiinka alxanka, 3 jeer 150HZ, 5 jeer 250HZ iyo wixii ka sareeya harmonics ayaa la soo saaray.Sidaa darteed, naqshadeynta magdhowga awoodda fal-celinta ee shaandhada labaad ee alxanka, inta jeer ee 150HZ, 250HZ iyo hareeraha waa in loo qaabeeyaa si loo hubiyo in wareegga magdhowga shaandhada uu si macquul ah u xakameyn karo garaaca garaaca wadnaha halka magdhowga culeyska falcelinta iyo hagaajinta awoodda arrin.
shaqada naqshadeynta
Qodobka awoodda dhamaystiran ee xariiqda wax soo saarka ee mishiinka alxanka labaad ee la mid ah 1000 kVA transformer ayaa magdhow laga bilaabo 0.7 ilaa 0.92.Qalabka sifaynta Qalabka magdhowga waa in lagu rakibaa awood dhan 550 kVA.9-ka kooxood ee capacitors ee ku jira kala qaybinta wejiga ayaa si toos ah ugu xidhan oo go'ay, kuwaas oo mid kastaa uu ku habboon yahay dabaylaha dhinaca korantada ee hoose ee beddelka.Awoodda hagaajinta fasalka waa 25KVAR, kaas oo buuxin kara shuruudaha tamarta kala duwan ee mashiinnada alxanka ee damaanadda labaad.Qodobka awoodda dhamaystiran ee mishiinka alxanka dammaanadda labaad ee ku habboon 630 kVA transformer ayaa magdhow laga bilaabo 0.7 ilaa 0.92.Qalabka magdhowga qalabka sifeynta waa in lagu rakibaa awood dhan 360 kVA.9-ka kooxood ee capacitors ee ku jira kala qaybinta wejiga ayaa si toos ah ugu xidhan oo go'ay, kuwaas oo mid kastaa uu ku habboon yahay dabaylaha dhinaca korantada ee hoose ee beddelka.Awoodda hagaajinta fasalka waa 25KVAR, kaas oo buuxin kara shuruudaha tamarta kala duwan ee khadka wax soo saarka.Naqshaddan ayaa ku filan si loo hubiyo in awoodda la hagaajiyay ay ka sarreyso 0.92.
Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Abriil 2010, shaandhada magdhowga tamarta falcelinta ee mishiinka alxanka ayaa laga soo raray warshadda.Qalabku wuxuu si toos ah ula socdaa isbeddelka culeyska ee mishiinka alxanka, wuxuu xakameeyaa awoodda falcelinta magdhowga isku midka ah waqtiga dhabta ah, wuxuuna wanaajiyaa qodobka awoodda.Faahfaahinta sida soo socota:
Kadib marka la isticmaalo aaladda magdhowga shaandhada, qalooca isbeddelka qodobka korantadu wuxuu ku saabsan yahay 0.97 (qaybta kor loo qaaday waxay ku saabsan tahay 0.8 marka qalabka shaandhada la saaro)
Hawlgalka load
Xilliga hadda shaqeeya ee 1000KVA Transformer wuxuu hoos uga dhacayaa 1250A ilaa 1060A, hoos u dhac 15% ah, iyo hadda shaqeynta 630KVA Transformer wuxuu hoos uga dhacayaa 770A ilaa 620A, hoos u dhac 19%.Magdhaw ka dib, qiimaha dhimista korantadu waa WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=24×{(0.85×2000)/2000}2×0.4≈16 (kw h) Qaaciddada, Pd waa luminta wareegga-gaaban ee transformer-ka, kaas oo ah 24KW, kaydinta kharashyada korantada ee sannadlaha ah waa 16*20*30*10*0.7=67,000 yuan (ku salaysan shaqada 20 saacadood a maalin, 30 maalmood bishii, 10 bilood sannadkii, 0.7 yuan halkii kWh).
xaaladda factor awood
Awoodda guud ee shirkaddu waxay kor u kacday 0.8 ilaa 0.95 bisha hadda jirta, awoodda bilaha waxay ahaan doontaa 0.96-0.98 mustaqbalka, gunnada bishiina waxay noqon doontaa 3000-5000 yuan.
gabagabadii
Qalabka magdhowga tamarta falcelinta filter-ka ee mishiinka alxanka koronto wuxuu awood u leeyahay inuu xakameeyo harmonics oo uu magdhabo awoodda falcelinta, xalliyo dhibaatada ganaaxyada tamarta falcelinta ee shirkadaha, kor u qaadida awoodda wax soo saarka ee transformers, yaraynta khasaaraha dheeraadka ah ee wax ku oolka ah, kordhinta wax soo saarka, oo keena dhaqaale weyn. faa'iidooyinka shirkadaha.Ku soo noqoshada maalgashiga wax ka yar hal sano.Sidaa darteed, qalabka magdhowga tamarta falcelinta ee ay shirkaddu soo saartay aad ayay ugu qanacsan tahay, waxayna soo jiidan doontaa macaamiil badan mustaqbalka.
