Przegl\u0105d produktu<\/h3>\n\n\n\n

Skrzynka stykov\u00e1 CHZ3-20kV\/250<\/a> jest produkowany przy u\u017cyciu procesu \u017cywicy epoksydowej APG (Automatyczne \u017belowanie pod Ci\u015bnieniem) ze struktur\u0105 formowania \u017celu pod ci\u015bnieniem. Jest to dedykowane urz\u0105dzenie izolacyjne do wysuwanych element\u00f3w klasy 20 kV. switchgear<\/a>g\u0142\u00f3wnie stosowany w rozdzielnicach wysuwanych klasy 20 kV montowanych centralnie. S\u0142u\u017cy do izolacji od\u0142\u0105czaj\u0105cej i po\u0142\u0105czenia przej\u015bciowego, zapewniaj\u0105c skuteczn\u0105 ochron\u0119 izolacyjn\u0105 styk\u00f3w wewn\u0119trznych w rozdzielnicy. Urz\u0105dzenie nadaje si\u0119 do zastosowa\u0144 w przesy\u0142aniu du\u017cych pr\u0105d\u00f3w i zapewnia bezpieczn\u0105 i stabiln\u0105 prac\u0119 systemu elektroenergetycznego.<\/p>\n\n\n\n

Zakres zastosowania<\/h3>\n\n\n\n

This contact box is applicable to 20 kV class centrally-mounted draw-out switchgear cabinets. It is commonly used in large-scale power distribution systems, industrial substations, high-rise building distribution rooms, and large mining and industrial enterprise power distribution systems requiring high-current transmission. It serves as an insulating protection and transitional connection component for internal contacts within the switchgear, providing reliable insulation assurance for the switching and isolation of high-voltage circuits, and meeting the demands of high-current power transmission.<\/p>\n\n\n\n

Warunki pracy<\/h3>\n\n\n\n

Temperatura powietrza otoczenia: od -10\u00b0C do +40\u00b0C; wilgotno\u015b\u0107 wzgl\u0119dna nie powinna przekracza\u0107 95% przy 25\u00b0C.<\/p>\n\n\n\n

The installation site shall be free of gases, vapors, dust, and other explosive or corrosive media that may significantly impair the insulation performance of the contact box.<\/p>\n\n\n\n

Urz\u0105dzenie powinno by\u0107 instalowane w miejscach wolnych od silnych wibracji i wstrz\u0105s\u00f3w mechanicznych, aby zapewni\u0107 integralno\u015b\u0107 konstrukcyjn\u0105.<\/p>\n\n\n\n

Przeznaczony do instalacji wewn\u0119trznej; kompatybilny z du\u017cymi konfiguracjami monta\u017cu szyn zbiorczych.<\/p>\n\n\n\n

Cechy produktu<\/h3>\n\n\n\n

Excellent Insulation Performance: Formed using the epoxy resin APG process, the contact box exhibits superior insulation properties, effectively isolating high-voltage circuits and preventing leakage and short-circuit risks while withstanding high-voltage impulses.<\/p>\n\n\n\n

High-Current Handling Capability: Rated current up to 4000 A, meeting the high-current transmission requirements of large power facilities while minimizing resistive heating losses.<\/p>\n\n\n\n

Robust and Durable Structure: The monolithic molded construction provides high mechanical strength, capable of withstanding both mechanical and electrical stresses within the switchgear enclosure, resulting in an extended service life.<\/p>\n\n\n\n

Effective Temperature Rise Control: Under continuous rated current operation, the temperature rise at the outlet terminal does not exceed 65\u00b0C, ensuring safe equipment operation and preventing failures caused by excessive thermal buildup.<\/p>\n\n\n\n

Ease of Installation: Standardized mounting dimensions compatible with conventional 20 kV centrally-mounted switchgear, facilitating on-site installation and replacement.<\/p>\n\n\n\n

Corrosion and Oxidation Resistance: The epoxy resin material offers excellent resistance to corrosion and oxidation, enabling reliable performance across a variety of complex electrical environments.<\/p>\n\n\n\n

Superior Surface Finish: Smooth, burr-free surface finish ensures convenient installation, with good flame-retardant and wear-resistant characteristics.<\/p>\n\n\n\n
