Matasa da Insulator

Akwai matasa biyar da ake amfani da su a wasu kungiyoyin karami: Pin, Suspension, Strain, Stay, da Shackle.

• Pin Insulator

• Suspension Insulator

• Strain Insulator

• Stay Insulator

• Shackle Insulator

An amfani da Pin, Suspension, da Strain insulators a cikin tashar tsari mai yawa zuwa mai yawan. Amma an amfani da Stay da Shackle Insulators kawai a cikin tashar tsari masu yawan.

Pin Insulator

Pin insulators suna cikin manyan abubuwan insulator da ake gina a kan karamin hawa, kuma suna da amfani sosai a cikin tashar karami har zuwa 33 kV. Zai iya gina su da wata, biyu, ko uku parts idan a nemi da tsari.

A cikin tashar 11 kV, ana amfani da insulator na wata part, wanda ake gina shi daga wata babban kayan china ko glass.

Saboda hanyar zama da insulator ya yi ita ce mafi girman sauran, in yi karfin girman tsakiyar ita don in yi girma mafi girma. Ana bayyana rain sheds ko petticoats a kan jikinsu don in samun girman tsakiyar ita mai yawa.

Waɗannan rain sheds ko petticoats suna da ma'aikatar gargajiya. A nan ne, ake gina waɗannan rain sheds ko petticoats ta haka don in ba a yi dami a kan kyakkyawar ita, amma kafin yake dami, yanayin ita bace yake ciwo da ba yake da tsarin magance-ba. Saboda haka, ba za a yi ƙofin tsarin magance-ba a kan pin insulator na dami.

A cikin tashar tsari mai yawa – kamar 33KV da 66KV – ya zama rasu a gina pin insulator na wata part. Idan tsari mai yawa, ya kamata insulator yake da tsarin mai yawa don in bayyana tsarin magance-ba. Wata kayan china insulator mai yawa ba shi daidai a gina ba.

A nan ne, ana amfani da pin insulator na parts biyu, inda ana fixi kayan china portland cement don in samun wata insulator daidai. Ana amfani da pin insulators na biyu parts a cikin 33KV, da uku parts a cikin 66KV.

Abubuwan Tsarin Electrical Insulator

Karamin tsari ana fixi a kan ƙarni na pin insulator, wanda ya ƙara tsarin magance-ba. Ƙarnin insulator ana fixi a kan tsaro na ƙarni a kan tsari. Insulator ya kamata in daidaito ƙwarewa a kan karamin tsari da ƙarni. Mafi girman lokaci mai tsakiya a kan karamin tsari da ƙarni, inda zai iya ƙara ƙwarewa a kan hawa, suna nufin flashover distance.

Idan insulator yake dami, kyakkyawar ita yake da tsarin magance-ba. Saboda haka, flashover distance na insulator yake ci. Tsarin electrical insulator ya kamata in ba da damar ciwon flashover distance a lokacin da insulator yake dami. Saboda haka, ƙarnin petticoat na pin insulator yake da tsarin umbrella don in mamaye ƙarfin ita daga rain. Kyakkyawar ƙarnin petticoat ta ƙarni yake ci ƙarin don in daidaito flashover voltage a lokacin da yake dami.

Rain sheds suna gina su ta haka don ba su ba maye tsarin tsari. Suna gina su ta haka don in sub-surface su yake da tsarin lami a kan electromagnetic lines of force.

Post Insulator

Post insulators suna da muhimmanci da pin insulators, amma post insulators suna da amfani sosai a cikin tashar tsari mai yawa.

Post insulators suna da ƙwarewa petticoats da girman mafi girma da pin insulators. Ana iya fixi wannan insulator a kan tsaro horizontali ko vertikal. Insulator yana gina shi daga wata kayan china, kuma akwai clamp arrangement a ƙarni da ƙarni don in fixi shi.

Muhimman farkon da ke cewa bayan pin insulator da post insulator sun hada:

Suspension Insulator

A cikin tashar tsari mai yawa, har zuwa 33KV, ya zama ba da rukuni a gina pin insulator saboda girman da kwayoyin insulator. In fitowa da in badalawa insulator mai girma yana da ƙwarewa. Don in taimaka waɗannan ƙwarewa, an gina suspension insulator.

A cikin suspension insulator, ana fixi insulators a kan series don in samun string, karamin tsari yana da shi a kan ƙarnin insulator. Kowane insulator a cikin suspension string suna nufin disc insulator saboda tsarin disc.

Muhimman Abubuwan Suspension Insulator

• Kowane disc suspension yana da tsarin voltage rating 11KV (Voltage rating mai yawa 15KV), saboda haka, tare da adadin discs, zai iya samun suspension string da zai iya amfani shi a cikin tashar tsari daban-daban.

• Idan wata disc insulator a cikin suspension string yake cika, zai iya badalawa shi da ƙwarewa.

• Tsari mai ƙwarewa a cikin suspension insulator yana da ƙwarewa saboda karamin tsari yana da shi a kan string mai ƙwarewa.

• Saboda karamin tsari yana da shi a kan supporting structure ta hanyar string, girman karamin tsari yana da ƙwarewa har zuwa girman supporting structure. Saboda haka, karamin tsari zai iya da damar ra'ayi.

Farkon Suspension Insulator

• Suspension insulator string yana da rukuni saboda pin da post type insulator.

• Suspension string yana bukatar girman supporting structure mai yawa saboda ground clearance na karamin tsari.

• Amplitudin free swing na karamin tsari yana da ƙwarewa a cikin suspension insulator system, saboda haka, zai bukatar ƙwarewa a kan spacing bayan karamin tsari.

Strain Insulator

String suspension da ake amfani da shi don hanen tensile loads ana nufin strain insulator. Ana amfani shi a cikin kungiyoyin karami har da dead end ko sharp corner, inda ana bukatar karamin tsari don in da shi tsari mai yawa. Strain insulator ya kamata da tsarin mechanical strength mai yawa da kuma tsarin electrical insulation.

Stay Insulator

A cikin kungiyoyin tsari masu yawan, ana bukatar stay wires da suka da insulator. Insulator da ake amfani a cikin stay wire ana nufin stay insulator, kuma ana gina shi ta haka don in ba su ba yake cika a kan ƙarfi idan insulator yake cika.

Shackle Insulator

Shackle insulator (ko spool insulator) ana amfani shi a cikin tashar distribution masu yawan. Ana iya amfani shi a cikin position horizontal ko vertical. Amfani da shi ya ci ƙarin a kan amfani underground cable don tashar distribution.

Tapered hole na spool insulator yana daidaito load ta daidai kuma yana ci ƙwarewa cikakken ciki idan yake da load mai yawa. Karamin tsari a groove na shackle insulator ana fixi shi ta haka don soft binding wire.
