Yuqori- va past-kuchlanishli quvvat taqsimlash shkaflarining printsiplari va tarkibiy qismlari

High- and low-voltage distribution cabinets are critical equipment within power systems, serving to distribute, control, and protect electrical energy; they are widely utilized across industrial, commercial, and residential sectors. Their core function is to facilitate the rational distribution and safe control of electrical energy-primarily through components such as circuit breakers, disconnect switches, and protective devices-while simultaneously providing protection against faults such as overloads, short circuits, and leakage currents. Classified by voltage level, low-voltage distribution cabinets (typically rated at ≤1000V) are primarily deployed for terminal power distribution, whereas high-voltage distribution cabinets (rated at >1000V) elektr energiyasini uzatish va taqsimlash vazifalarini bajarish; birgalikda, bu ikki tur keng qamrovli quvvat taqsimlash tarmog'ini tashkil qiladi.

 

Texnik tamoyillari va strukturaviy tarkibi
Yuqori- va past kuchlanishli taqsimlovchi shkaflarning konstruktiv dizayni xavfsizlik, ishonchlilik va texnik xizmat ko'rsatish qulayligi o'rtasidagi muvozanatni saqlashi kerak. Past kuchlanishli taqsimlovchi shkaflar odatda metall materiallardan (masalan, sovuq haddelenmiş po'lat plitalar kabi) modulli dizaynga ega bo'lib, chang va suv kirib kelishidan samarali himoya qilish uchun IP40 dan IP54 gacha bo'lgan kirish himoyasi (IP) darajasini taklif qiladi. Ichki komponentlarga kiruvchi kalitlar, chiquvchi elektron kalitlar, o'lchash moslamalari va himoya modullari kiradi, quvvat taqsimoti shinalar orqali osonlashtiriladi. Yuqori{9}}kuchlanishli taqsimlovchi shkaflar, aksincha, vakuum to'xtatuvchilari, asboblar transformatorlari va kuchlanish to'xtatuvchilari- kabi yuqori kuchlanishli komponentlarni-integratsiyalashni talab qiladi va yuqori kuchlanish sharoitida barqaror va ishonchli ishlashini ta'minlash uchun SF6 gaz izolatsiyasi yoki qattiq izolyatsiya texnologiyalaridan foydalanadi{1}}.
