Subway aluminium conductive reli

Subway aluminium conductive reli is a new type of conductor rail superior to old low carbon steel conductor rail. It is widely used as conductor rail. Imetengenezwa kwa chuma cha chini cha aloi ya kaboni na aloi ya alumini. Aloi ya alumini ni mwili kuu wa reli ya kondakta. Wakati wa kuchagua vifaa vya chuma, upinzani wake wa kuvaa, Upinzani wa kutu na conductivity ni hasa kuchukuliwa. Chromium chuma kwa ujumla kuchaguliwa, na upinzani wake wa kuvaa, conductivity na conductivity ya mafuta inaweza kimsingi kukidhi mahitaji ya chuma alumini composite conductor reli.

Subway aluminum conductive rail is mainly used for urban rail transit and electrified railway transmission system. Ikilinganishwa na reli ya chini ya kaboni ya chini ya chuma, Ina faida kadhaa, kama upinzani wa chini, uzito mwepesi, Upinzani wa kutu, Nguo ndogo, Nk. Inaweza kuokoa kuhusu 60% Kupoteza nguvu na maisha ya huduma itakuwa zaidi ya 50 Miaka.

Maelezo ya kibiashara:

Subway aluminum conductive rail also known as third rails or contact rails, are an essential component of the electric power supply system for many subway trains. These rails are designed to conduct electricity and provide a continuous flow of power to the trains as they move along the tracks.

Typically, aluminum is used as the primary material for these conductive rails due to its high electrical conductivity, uzito mwepesi, and resistance to corrosion. The aluminum rail is usually covered with a layer of carbon-based composite material or stainless steel to improve its durability and reduce wear caused by the contact shoes of the train.

The conductive rail is usually mounted on insulators along the side or center of the track, and it is kept at a constant voltage potential. When the train moves over the rail, the contact shoes on the underside of the train make contact with the rail, completing an electrical circuit and drawing power from the rail to drive the train’s electric motors.

It is important to ensure that Subway aluminum conductive rail is properly maintained and kept free of debris or obstructions that could interfere with the flow of electricity. Hayo, safety measures such as insulation and warning signs are typically in place to protect people from coming into contact with the high-voltage rail.

Vifaa vya chuma na alumini vya reli ya kondakta wa alumini ya chuma ni mchanganyiko wa metallurgy imara ya ukanda wa chuma uliosafishwa na wasifu wa alumini katika ukungu wa kuchanganya kulingana na vigezo vya kawaida vya mchakato. Mchanganyiko huu wa metallurgiska huundwa kupitia jukumu la joto na shinikizo katika mchakato wa kneading, na kwa safu maalum ya conductive. Katika mchakato huu, kiwanja cha chuma Al3Fe2 imeundwa kati ya atomi za alumini na chuma, na kuunganisha metallurgiska kati ya vifaa viwili kutapunguza upinzani wa interlayer. Kwa kuwa hakuna pengo kati ya uso wa mawasiliano ya chuma na alumini, Anwani ya mawasiliano sio rahisi kutu na kuharibiwa, ambayo inaweza kuhakikisha utulivu wa upinzani wa chini kwa muda mrefu. Zaidi ya hayo, Mtihani wa peel umethibitisha kuwa haiwezekani kusugua ukanda wa chuma kutoka kwa mwili wa aluminium. Vitu maalum tu vinaweza kutenganisha chuma kutoka kwa alumini. Mchanganyiko wa metallurgiska kati ya chuma na alumini unaweza kuhimili nguvu kubwa za nje bila deformation.

Zaidi ya hayo, Matatizo kama vile kutokwa na damu, scratches na scratches juu ya uso chuma ni kuruhusiwa kutokea wakati wa usindikaji bila kuathiri practicability ya bidhaa.

Reli ya kondakta wa alumini ya chuma imetengenezwa kwa chuma cha aloi ya kaboni ya chini na aloi ya alumini. Aloi ya Aluminium ni mwili kuu wa reli ya kondakta. Wakati wa kuchagua vifaa, Kazi yake bora ya uendeshaji lazima izingatiwe na kukidhi mahitaji ya kazi ya mitambo. Kwanza kabisa, Upinzani wa kuvaa, Upinzani wa kutu na conductivity ya chuma inapaswa kuzingatiwa. Chromium chuma kawaida huchaguliwa, na upinzani wake wa kuvaa, conductivity na conductivity ya mafuta inaweza kimsingi kukidhi mahitaji ya chuma alumini composite conductor reli.

Reli ya kondakta wa alumini ya chuma imeonekana kuwa bidhaa muhimu na ya kuaminika katika matumizi ya muda mrefu. Ikilinganishwa na reli ya chini ya kaboni, Ina faida zifuatazo:
(1) conductivity ya aloi ya alumini ni 28-33ms / m, 3-4 nyakati zile za chuma cha chini cha kaboni isiyo ya aloi (8.5Ms / M). conductivity ya chuma alumini composite conductor ni juu kuliko ile ya chini kaboni chuma kondakta. Katika fomu hii mpya ya vifaa, Kupunguza voltage hupunguza matumizi ya nishati ya kuvuta kwa uwiano, ambayo huongeza umbali wa usambazaji wa umeme na kupunguza idadi ya substations.
(2) Uzito maalum ni mdogo, Na vifaa ni rahisi kujenga: Uzito wa kondakta wa chuma cha alumini ni chini ya nusu ya uzito wa kondakta wa chini wa chuma cha kaboni na sehemu sawa ya msalaba. Vifaa ni rahisi, Gharama ni ndogo, Gharama ni nzuri, Na hakuna haja ya vifaa vya kuinua.
(3) Upinzani mzuri wa kutu na upinzani wa kuvaa: Kuhakikisha upinzani bora wa kutu na kuvaa upinzani wa ukanda wa chuma, Reli ya kondakta wa alumini ya chuma imetengenezwa na chuma cha pua cha chromium na upinzani bora wa kutu ya intergranular. Reli ya kondakta ina upinzani bora wa kutu wakati vifaa vinaendeshwa na kupimwa katika maabara chini ya hali ya hewa ya baharini. Wakati huo huo, Uso wa mawasiliano ya chuma cha pua ni laini na sugu, ambayo inaweza kupanua maisha ya huduma ya reli ya kondakta na mtoza.
(4) Upinzani mzuri: Mchanganyiko wa kneaded wa alumini na chuma cha pua unaweza kuunda maelezo anuwai.
(5) Faida nzuri za kiuchumi: chini ya kiasi sawa cha usafirishaji, gharama ya chuma alumini composite conductor reli ni chini kuliko ile ya reli ya chini kaboni. Hii ni kwa sababu ya: 1) Voltage hupungua na mahitaji ya substation hupungua; 2) Reli ya kondakta wa alumini ya chuma ni nyepesi kwa uzito, Kupunguza gharama za vifaa; 3) Gharama ya kila mwaka ya digestion ni ndogo.
