Waxaa jira dhowr tillaabo oo tijaabada hawlgalka ee tijaabiyaha iska caabbinta dahaarka

Tijaabada iska caabbinta dahaarka waxaa inta badan loo isticmaalaa in lagu cabbiro caabbinta dahaadhka ee Transformers, transformers, koronto-dhaliyeyaasha, matoorrada korantada sare, capacitors, fiilooyinka korontada, xirayaasha iyo qalabka kale.

GD3127/3128 Tijaabada iska caabbinta dahaarka

Tallaabooyinka hawlgalka iyo tijaabinta tijaabiyaha iska caabbinta dahaarka:

(1) Ruxruxuhu waa in lagu doortaa iyadoo loo eegayo heerka korantada ee qalabka.Transformers of 10KV-35KV, 2500 volt ruxruxo waa in loo isticmaalo.

(2) Ka hor inta aan la cabbirin caabbinta dahaarka, waa in la gooyaa korontada qalabka lagu tijaabinayo, iyo Samaynta dareeraha wareegga gaaban, ujeedada dheecaanku waa in la ilaaliyo badbaadada dadka iyo qalabka, iyo in la sameeyo cabbirka. natiijooyinka saxda ah;

(3) Xidhiidhka gariirku waa inuu noqdaa laba xadhig oo kala gooni ah (laba midab) oo leh dahaar wanaagsan, laba ha isku maroojin fiilooyinka isku xidha, hana ka dhigin fiilooyinka isku xidha inay la xidhiidhaan dhulka, si looga fogaado khaladaadka ay sababto saboolnimada. dahaarka fiilooyinka isku xirka;

(4) Kahor intaanad cabbirin, samee tijaabada wareegga furan iyo wareegga gaaban ee ruxuliyaha si aad u hubiso in ruxruxuhu uu xaaladdiisu wanaagsan tahay iyo in qalabka beddelka uu dahaaran yahay.Haddii tijaabiyaha iska caabbinta uu furo labada xariiq ee isku xira oo uu ruxo gacanta, tilmaamuhu waa in uu tilmaamaa ∞ (infinity).Waqtigaan, haddii labada xariiq ee isku xira ay yihiin kuwo gaaban wareega, tilmaamuhu waa inuu tilmaamayaa 0, taas oo macnaheedu yahay in ruxruxuhu uu xaalad fiican ku jiro., haddii kale waxaa jira qalad miiska gariiraya;

(5) Habka fiilooyinka ee ruxitaanka caabbinta dabaysha ee dabaysha aasaasiga ah ee dabaysha sare iyo dhulka (qofof): Wareeg gaaban ee terminaalka saddex-waji ah lU, lV iyo 1W ee dabaysha aasaasiga ah oo leh fiilooyinka naxaasta ah, siday u kala horreeyaan. in lagu xidho "L" dhamaadka megohmmeter;gaaban wareegyada N, 2U, 2V, 2W iyo dhulka ( qolofka dhulka) ee dabayllaha sare ee leh fiilooyin naxaas ah oo qaawan, ka dibna ku xidh dhammaadka "E" ee megohmmeter;Haddii loo baahdo, si loo yareeyo saamaynta daadinta dusha sare ee qiimaha la cabbiray, silig naxaas ah oo qaawan ayaa lagu dhaawaci karaa marada suufka ah ee gacanka hoose ee dhinaca hoose ee dhowr leexo, ka dibna lagu xiro "G" dhamaadka megohmmeter oo leh silig dahaaran;

(6) Rux cabbirka labada dabaylood ee labaad Habka fiilooyinka ee caabbinta dahaarka ee dabaylaha aasaasiga ah iyo dhulka (qofof): wareeg-gaaban 2U, 2V, 2W, iyo N ee dabaysha sare ee leh fiilooyin naxaas ah oo qaawan. .Si loogu xiro "L" dhamaadka megohmmeter;ka dib markii la gaabiyay wareegtada saddexda weji ee hogaaminaya 1U, 1V, 1W iyo dhulka (Qofka) ee dabaylaha aasaasiga ah ee leh fiilooyinka naxaasta ah, ku xidh dhamaadka "E" ee megger;Si loo yareeyo saamaynta daadinta dusha sare ee qiimaha la cabbiray, silig naxaas ah oo qaawan ayaa lagu dhaawaci karaa hareeraha marada suufka ah ee gacanka labaad ee suufka galka dhowr wareeg, ka dibna lagu xiro "G" dhamaadka megohmmeterka oo leh silig daahan .

(7) Markaad cabbirayso, ku cadaadi qolofta ruxruxaha hal gacan (si aad uga ilaaliso ruxruxa).Marka tilmaamuhu muujiyo 0, jooji ruxmada isla markiiba si aad uga fogaato gubashada saacadda;

(8) Markaad cabbirayso, dhig miiska gariiraya meel toosan, u rog gacanta ruxaysa koronto-dhaliyaha xawaare dhan 120 kacdoon daqiiqaddii, oo akhri 15s Qaado lambar (R15), akhri nambar kale (R60) at 60s, oo duub xogta ruxaysa.
