Maimakon Mata Yadda Ake Tattara Daga Zuba da Porcelain Insulators

Zuba da kuma porcelain insulators suna amfani da su masu yawa a fadada gajarta da tashin karkarwa don in tattara mafi girman jikin da ke ciki daga kofin ko kofin da ke ciki. Saboda lokacin da aka yi ake yi da ma'ana da kuma idan da za a iya amfani da su a matsayin abubuwan da na karkarwa, mutanen da suka samun da damar da kyau sun nuna muhimmin abubuwan da suke amfani da su a wurare da rike.

Porcelain Insulators

Porcelain, wata abu mai kyau, ana ambaci saboda rashin da ba ake da shi a kan mulkin magana kamar voids, cracks, ko thermal expansion idan an yi da ma'ana. Ana rawa shi daga china clay (aluminum silicate mai yawa), da plastic kaolin, feldspar (wata crystalline silica stone), da kuma quartz (silicon dioxide, SiO₂). Wannan rawa ce an yi da shi a kiln a hanyar tsari da ma'ana don in yi insulator mai kyau, mai sauƙi, da kuma mai karfi da ba ake da porosity.

Porcelain insulator mai kyau ya nuna dielectric strength ta 60 kV/cm, compressive strength ta 70,000 kg/cm², da kuma tensile strength ta kusan 500 kg/cm². Cement shine da shi a matsayin abu mai rawa, wanda ya zama cewa porcelain insulators suna da amfani da su a matsayin abubuwan da ake amfani da su a fadada gajarta da tashin karkarwa na duniya.

Glass Insulators

Toughened glass shine da shi a matsayin abu mai kyau waɗannan insulators. An yi glass da shi a hanyar heating, melting, da kuma controlled cooling process (tempering), wanda ya nuna dielectric strength ta kusan 140 kV/cm.

Toughened glass suspension insulators suna amfani da su a matsayin abubuwan da ake amfani da su a fadada gajarta na karkarwa (≥ 500 kV) na duniya. Da high resistivity, design transparent shine da shi ya nuna muhimmin abubuwan: insulators da suka haifar da shi ko arced insulators za su iya tabbatar da shi a hanyar visual inspection. Glass insulators sun nuna compressive strength ta 10,000 kg/cm² da kuma tensile strength ta 35,000 kg/cm².

Core Contrasts

Porcelain insulators, da ake rawa daga abubuwan ceramic, suna da kyau a matsayin compressive strength (70,000 kg/cm²) amma suna da tensile strength mai tsawo (500 kg/cm²), da ya fi amfani da su a matsayin abubuwan da na karkarwa mai kyau (<500 kV). Glass insulators, da ake rawa daga toughened glass, sun nuna dielectric strength mai kyau (140 kV/cm) da kuma mechanical properties mai kyau (compressive strength 10,000 kg/cm², tensile strength 35,000 kg/cm²), da ya fi amfani da su a fadada gajarta extra-high voltage (≥ 500 kV). Transparency glass ya nuna muhimmin abubuwan: faults ko arced insulators za su iya tabbatar da shi a hanyar visual inspection, amma non-transparent nature da porcelain ke da shi ya nuna irin physical inspection. Idan an yi da cost initial mai kyau, glass insulators suna bukatar da maintenance mai tsawo da kuma suna da lifespans mai kyau, wanda ya zama cewa suke fi amfani da su a fadada gajarta na karkarwa idan akwai zaruratun reliability.
