Misali da karamin shiga da tushen karami?
Zai na ne Transmission Tower?
Takaitaccen Transmission Tower
Transmission tower yana nufin karamin tashar da ake amfani da ita don sabunta jirgin kasa daga masanin kasa zuwa substations.
Karamin Transmission Tower
Tower da ake amfani da shi wajen sabunta jirgin kasa yana da muhimmanci a cikin systemen jirgin kasa, kuma yana da karamin:
Gidan transmission tower
Cross arm na transmission tower
Boom na transmission tower
Cage na transmission tower
Jikin transmission tower
Sokki na transmission tower
Stub/Anchor Bolt da Baseplate assembly na transmission tower.
Karamomin da suka bayyana a nan. Koyaya cewa gudummawa na wannan towers ba shi da mutum, kuma akwai metodologi na gudummawa ga jirgin kasa mai tsayi.
Muhimmancin Takaito
Transmission towers ya kamata zama tushen karamin conductors mai tsayi da kuma damar harsuna, wanda ya ba da takaito mai kyau a cikin civil, mechanical, da electrical fields.
Karamomin Transmission Tower
Karamomin mafi muhimmanci sun hada da gida, cross arm, boom, cage, body, legs, da baseplate assembly, kwararruwan da suka taka rawa a cikin gwamnatiyar tower.
Cross Arm na Transmission Tower
Cross arms suka bincike transmission conductors. Girman su ya kasance a kan transmission voltage, configuration, da stress distribution angle.
Cage na Transmission Tower
Babban karamin da ke cikin jiki da gida ake kira cage na transmission tower. Wannan karamomin tower yana bincike cross arms.
Jikin Transmission Tower
Jikin tower yana zama daga cross arms ta hagu zuwa tsakiya, kuma yana da muhimmanci wajen inganta clearance da ke cikin ground na conductor ta hagu na jirgin kasa.
Takaito na Transmission Tower
A lokacin takaito na transmission tower, karamomin da suka samun lura su ne
Minimum clearance na ground da ke cikin lowest conductor point a fadada ground level.
Girman insulator string.
Minimum clearance da ke da shi bayan conductors da kuma bayan conductor da tower.
Ingantaccen ground wire game da outermost conductors.
Midspan clearance da ke cikin considerations of the dynamic behavior of the conductor and lightning protection of the power line.
Don tabbatar da girman tower daga abubuwan da suka bayyana, an saurari girman total da tower a kan wauci:
Minimum permissible ground clearance (H1)
Maximum sag of the overhead conductor (H2)
Vertical spacing between the top and bottom conductors (H3)
Vertical clearance between the ground wire and top conductor (H4)
Jirgin kasa mai tsayi sun bukata clearance mai yawa da spacing vertical. Saboda haka, towers mai tsayi suna da clearance mai yawa da spacing mai yawa bayan conductors.
Abunukan Electrical Transmission Towers
Daga cikin abubuwan da suka faru, akwai abunukan transmission towers.
Jirgin kasa yana ci gaba da kokarin corridors. Saboda babu korridor mai tsayi, jirgin kasa yana iya ci gaba daga rukunin da ke faru idan akwai obstruction. A cikin girman jirgin kasa mai yawa, akwai matsayin abunukan deviation points. Daga cikin angle na deviation, akwai waucin transmission tower
A – type tower – angle of deviation 0o to 2o.
B – type tower – angle of deviation 2o to 15o.
C – type tower – angle of deviation 15o to 30o.
D – type tower – angle of deviation 30o to 60o.
Daga cikin force applied by the conductor on the cross arms, transmission towers zai iya canzawa da tare da
Tangent suspension tower and it is generally A – type tower.
Angle tower or tension tower or sometime it is called section tower. All B, C and D types of transmission towers come under this category.
Ba a cikin abunukan da aka bayyana, tower an yi design don meet special usages listed below:
Wadannan suna kiran special type tower
River crossing tower
Railway/ Highway crossing tower
Transposition tower
Based on numbers of circuits carried by a transmission tower, it can be classisfied as
Single circuit tower
Double circuit tower
Multi circuit tower.
Takaito na Transmission Tower
Takaito sun haɗa da ground clearance, conductor spacing, insulator length, ground wire location, and midspan clearance, wadannan suna da muhimmanci don safe and efficient operation.
