Kelebihan Produk Teras

1. Prestasi Penebat Cemerlang, Sesuai untuk Persekitaran yang Kompleks

The vacuum interrupter employs a fully embedded epoxy resin housing design, significantly enhancing the equipment's overall insulation and providing robust resistance against pollution, moisture, and condensation. Standard models operate stably at altitudes of 1,000 meters or below, while customization options for ultra-high altitudes are available to meet the operational requirements of diverse, specialized environments.

2. Hayat Perkhidmatan Luar Biasa, Menyokong Operasi Kerap

VCB 11kV 630A mempunyai jangka hayat mekanikal dan keupayaan pemecahan arus dinilai sehingga 20,000 operasi. Ia menyokong sehingga 50 operasi pada arus litar pintas maksimum dan memastikan prestasi pecah yang stabil untuk sekurang-kurangnya 30 operasi di bawah keadaan litar pintas 40kA. Ia amat sesuai untuk senario yang melibatkan kitaran mula-henti peralatan yang kerap dan penukaran talian berulang, dengan berkesan mengurangkan kekerapan penggantian peralatan dan kos penyelenggaraan jangka panjang.

3. Perlindungan Litar pintas Teguh Memastikan Keselamatan Sistem

The product features a maximum rated short-circuit breaking current of 40 kA and a peak withstand current of up to 100 kA. In the event of sudden faults such as short circuits or overloads, it rapidly interrupts fault currents and isolates faulty equipment. This prevents fault propagation—thereby avoiding widespread power outages and equipment damage—and comprehensively safeguards the operational safety of the power distribution system.

4. Parameter Operasi Tepat dan Kebolehoperasian yang Kuat

Pemutus Litar Vakum 11kV 630A menawarkan parameter operasi yang tepat dan stabil: masa penyimpanan tenaga ≤10s, jarak buka sentuhan 11±1mm, lebihan perjalanan sentuhan 3.5±0.5mm, kelajuan buka/tutup purata 1.2±0.2m/s, dan penyegerakan tiga fasa. Ia menyokong jujukan operasi "0-0.3s-CO-180s-CO" standard dan disepadukan dengan lancar dengan pelbagai peranti perlindungan kuasa untuk membolehkan perlindungan kuasa yang pintar dan terkawal dengan ketepatan.

Kes Aplikasi Dunia Sebenar

Kajian Kes 1: Retrofit Pengagihan Kuasa untuk Loji Kimia Pantai

Sebuah loji kimia yang besar di China Timur, terletak di kawasan pantai, mengalami masalah di mana kelembapan yang tinggi dan semburan garam menyebabkan penebat penuaan dan kerap tersandung pada pemutus litar tradisional, sekali gus mengganggu operasi stabil barisan pengeluaran. Perusahaan itu menaik taraf sistem pengagihan kuasa 11kV menggunakan Pemutus Litar Vakum (VCB) HUAJIDIAN 11kV 630A. Produk ini mempunyai struktur penebat tertutup pepejal yang berkesan menahan kakisan semburan garam dan kemasukan lembapan. Peralatan ini telah beroperasi secara berterusan selama 24 bulan tanpa kegagalan penebat atau tersandung yang tidak normal, memastikan pengeluaran tidak terganggu dan membantu perusahaan mengurangkan kos dan kerugian O&M daripada masa henti sebanyak lebih 15%.

Kajian Kes 2: Projek Operasi Frekuensi Tinggi di Taman Perindustrian

A manufacturing industrial park in Central China houses numerous motors and transformers that require frequent starting and stopping, placing extremely high demands on the service life and operational durability of circuit breakers. The park deployed HUAJIDIAN 11kV 630A VCBs across the board for 11kV branch line protection. With an ultra-long service life of 20,000 operations, the units are perfectly suited for high-frequency switching conditions. The equipment has operated fault-free for a year, resolving issues common to traditional circuit breakers—such as premature aging and damage—and significantly enhancing the reliability of the industrial power supply.

Soalan Lazim

S1: Apakah keadaan operasi yang teruk yang boleh tahan oleh Pemutus Litar Vakum HUAJIDIAN 11kV 630A?

Produk ini mempunyai daya tahan alam sekitar yang luar biasa; model standard sesuai untuk ketinggian sehingga 1,000 meter, manakala model tersuai boleh memenuhi keperluan ketinggian yang lebih tinggi. Struktur tertutup pepejal resin epoksinya memberikan ketahanan yang sangat baik terhadap lembapan, pencemaran dan semburan garam, memastikan operasi jangka panjang yang stabil dalam persekitaran yang mencabar seperti kawasan pantai lembap, loji perindustrian berdebu dan kawasan altitud tinggi bertekanan rendah.

Q2: What are the key advantages of this product for high-frequency operation scenarios?
