Muhimmanci Ma'adani don Sistomin Tururun Turbin Mai Turru
Duk fitaccen tururun turu da za a yi shiga da suka shafi da tushen mai sarrafa;
Sistemai mai turru na da gagarin mai tsarki da yake da duwatsu masu hanyar jirgin kisan gagarin da ya fi sani. Idan gagarin da ya fi sani yake soke, gagarin da ya fi dace yana da shawarwa da kuma yana da shawarwar samun kwakwalwa da sauti;
Don turubin da ke da gagarin mai tsarki, idan wani fitaccen mai tsarki yake ci, yana da shawarwar samun kwakwalwa da sauti, kuma fitaccen da ya fi dace yana da shawarwa (da yawa da yadi don gagarin mai ruwa);
Motoyin da suka shiga da fans, pumpin ruwa, da pumpin mai tsarki suna da ingantaccen labaran gaba, kisan hanyar, da kuma gaba da tsari; yana da wurare da suka shiga da rike hukumar da motoyin pumpin mai tsarki ke yi;
Don heat exchangers na da gagarin ruwa, pumpin mai tsarki yana da shiga ne a fadin da take da tsarki ta fitaccen mai tsarki, tare da cewa pressure da ke tsarki a fitaccen mai tsarki yana da zama da 0.05MPa daidai da pressure da ke ruwa a duk lokacin (illa da yadda mai sarrafa ya bayar da ba). Yana da plug da ke da shiga ruwa a fadin da take da ruwa ta fitaccen mai tsarki;
Don turubin da ke da gagarin mai tsarki da gagarin mai ruwa, yana da check valve da ke shiga a fadin da take da gagarin mai tsarki ta wata submersible oil pump;
Turubin da ke da gagarin mai tsarki da yake da shawarwa da kuma da yake da shawarwar samun temperature da kuma load.
Funkshin Fitaccen Mai Tsarki na Turubin
Idan akwai farko na tsari da ke da tsarki a fadin da ke da tsarki a baya a turubin, yana da gargaɗi mai tsarki da ke shiga da fitaccen mai tsarki. Ba da damar da aka tsarki a fitaccen mai tsarki, tsarki yana shiga zuwa tank, wanda yake da ƙarin da tsarkin turubin.
Hanyoyin Mai Tsarki na Fitaccen Mai Tsarki na Turubin
Oil-immersed natural air cooling method;
Oil-immersed forced air cooling method;
Forced oil circulation water cooling method;
Forced oil circulation air cooling method;
Forced oil circulation directed cooling method.
A cikin 500kV substations, turubin masu yawan yana da shawarwa da hanyar forced oil circulation air cooling method, amma turubin masu yawan da yawan yana da shawarwa da hanyar forced oil circulation directed cooling method.
Prinsipin Funtshi na Fitaccen Mai Tsarki na Turubin
Turubin masu power da suka shiga da fans da suka shiga da yawa, da har turubin da ke da 6 groups of air-cooled motors da suka shiga da shawarwa. Har group of fans yana da thermal relays da suka shiga da funtshi, da fan power circuits da suka shiga da contactors. Fans suna da shawarwa da kuma suka shiga da logical judgments da aka yi dari measurements of the transformer's oil temperature and overload conditions.
Mechanical contacts suna da shawarwa da mechanical contacts. Hanyar shawarwan yawa suna da shawarwa da yawa. Amma, abin da yake da shawarwa mafi yawa shine cewa fans duka suna da shawarwa da kuma suka shiga da dace, wanda yake da inrush currents da ke da shawarwa da kuma suka shiga da dace, da kuma suka haɓaka components a cikin circuit. Daga lokacin da temperatures suna da 45 to 55 degrees Celsius, fans duka suna da shawarwa da kuma suka shiga da dace, wanda yake da energy waste da kuma suka haɓaka difficulties for equipment maintenance.
Cooling control systems masu yawan suna da shawarwa da components like relays, thermal relays, and various contact-based logic circuit control systems, da control logic da yake da shawarwa. A lokacin da shawarwan yawa, contactors suna da shawarwa da kuma suka shiga da dace saboda repeated contact and separation of contacts. Da kuma, fans suna da shawarwa da kuma suka shiga da dace, amma babu ingantaccen protections like overload, phase loss, and overcurrent protection, wanda yake da operational reliability da kuma suka haɓaka operating costs during actual operation.
Components of Forced Oil Forced Air Cooled Transformer Coolers
Fitaccen mai tsarki yana da heat exchangers, fans, motors, air ducts, oil pumps, and oil flow indicators. Cooling fans suna da shawarwa da hot air da ke shiga da heat exchangers. Oil pump yana da shiga ne a baya fitaccen mai tsarki don tsarki da ke shiga da fadin da ke da tsarki ta fitaccen mai tsarki. Oil flow indicator yana da shiga ne a fadin da ke da fitaccen mai tsarki don operators don shiga da shawarwar da operational status of the oil pump.
Funkshin Tank na Turubin da Fitaccen Mai Tsarki
Tank na turubin yana da shawarwa da outer casing of the transformer, containing the iron core, windings, and transformer oil, while also providing a certain degree of heat dissipation.
Funkshin fitaccen mai tsarki na turubin shine cewa yana da shawarwa da oil circulation through the radiator when a temperature difference exists in the upper oil layer of the transformer. Wannan yana da shawarwa da oil da ke shiga da radiator before flowing back into the tank, effectively reducing the transformer oil temperature. To enhance cooling efficiency, measures such as air cooling, forced oil forced air cooling, or forced oil water cooling can be adopted.
