Misalai na Turayi na Idajiya
Turayi na idajiya (wanda ake kira turayin idajiya, turayin idajiya, ko pylon) shine darakinsu (gaskiya tana da darakin lattisin harshe) wanda ake amfani da shi don inganta tsarin idajiya na yankin. A cikin grids na idajiya, ana amfani da su don jiragen tsarin idajiya mai girma idajiya wadanda ke jiragen idajiyar da ta zama a kan abubuwa na idajiya zuwa sub-stations; ake amfani da poles na utilities don inganta tsarin idajiya mai haske uku da distribution lines wadanda ke jiragen idajiya daga sub-stations zuwa mutanen idajiya.
Turayi na idajiya suna da muhimmanci a kan jiragen tsarin idajiya mai girma a wurin da ya fi dace da tsakiyar. Da kuma wannan, duk turayi suna da muhimmanci a kan tabbatar da dukkan nau'ukan gida. Saboda haka, tashin turayi na idajiya shine babban aiki na engineering inda misalai na civil, mechanical, da electrical engineering suna da muhimmanci.
Abubuwan Turayin Idajiya
Turayin idajiya shine mahimmiyar banga a cikin system na idajiya. Turayin idajiya tana da abubuwan da suka:
Gaskiya na turayin idajiya
Cross arm na turayin idajiya
Boom na turayin idajiya
Cage na turayin idajiya
Kofin Turayin Idajiya
Leg na turayin idajiya
Stub/Anchor Bolt da Baseplate assembly na turayin idajiya.
An bayyana waɗannan abubuwa a cikin. Koyaya, tashin waɗannan turayi ba shi da karfi, akwai methodology na erection a cikin tashin waɗannan turayi mai girma na idajiya.
Gaskiya na Turayin Idajiya
Babu a cikin gaskiya na cross arm na turayin idajiya an kira gaskiya. Gaskiya wire na earth shield tana magance a cikin gaskiya na wannan.
Cross Arm na Turayin Idajiya
Cross arms na turayin idajiya suna da idajiya. Tsari na cross arm tana neman da level na voltage, configuration, da minimum forming angle don stress distribution.
Cage na Turayin Idajiya
Babu a cikin kofi na turayin idajiya zuwa gaskiya an kira cage na turayin idajiya. Wannan babu na turayi tana da cross arms.
Kofin Turayin Idajiya
Babu a cikin cross arms na kafin zuwa tsakiya an kira kofin turayin idajiya. Wannan babu na turayi tana da muhimmanci a kan tabbatar da ground clearance mai girma na conductor na tsarin idajiya.
Tashin Turayin Idajiya
A cikin tashin turayin idajiya, muna iya duba waɗannan abubuwa a cikin:
Ground clearance mai girma na lowest conductor point a cikin tsakiya.
Tsari na insulator string.
Clearance mai girma da ke da ita a cikin conductors da kuma a cikin conductor da turayi.
Location na ground wire a cikin outermost conductors.
Midspan clearance required from considerations of the dynamic behavior of the conductor and lightning protection of the power line.
Don tabbatar da tsari mai girma na turayin idajiya, muna iya divide total height na turayi zuwa waɗannan parts:
Minimum permissible ground clearance (H1)
Maximum sag na overhead conductor (H2)
Vertical spacing between the top and bottom conductors (H3)
Vertical clearance between the ground wire and top conductor (H4)
Idan voltage na tsarin idajiya yana fi girma, ground clearance da kuma vertical spacing tana da muhimmanci a yi. Yana nufin cewa, turayi mai girma suna da ground clearance mai girma da kuma vertical spacing mai girma a cikin top da bottom conductors.
Abubuwan Turayin Idajiya
Daga cikin abubuwan da suka samu, akwai abubuwan turayin idajiya.
Tsarin idajiya tana haɗa a cikin corridors da aka bayar. Idan a ba da corridor mai girma da take haɗa, tsarin idajiya tana da buƙata a cikin straightway. A cikin tsari mai girma na tsarin idajiya, akwai several deviation points. Daga angle na deviation, akwai abubuwan turayin idajiya–
A – type tower – angle of deviation 0° to 2°.
B – type tower – angle of deviation 2° to 15°.
C – type tower – angle of deviation 15° to 30°.
D – type tower – angle of deviation 30° to 60°.
A cikin force na conductor a cikin cross arms, turayin idajiya suna da classification wasu–
