框架斷路器DW17-1900 1250A 4P 電動快速插入式220V
產(chǎn)品概述（中英文）
DW17-1900框架斷路器是一款高性能配電保護設備，適用于交流50Hz、額定電壓400V至690V的配電網(wǎng)絡。該產(chǎn)品采用1250A額定電流設計，4極結構（4P），配備電動快速操作機構和插入式安裝方式，支持AC220V控制電壓。其核心功能包括電能分配、線路保護以及電源設備的過載、短路防護，同時具備不頻繁電路轉換能力。斷路器采用模塊化設計，主觸點采用銀合金材料確保導電性能，滅弧系統(tǒng)能有效分斷故障電流。抽屜式結構便于維護，面板配備分合閘狀態(tài)指示和手動操作按鈕，可適配多種電氣附件擴展功能。The DW17-1900 frame circuit breaker is a high-performance power distribution protection device designed for AC 50Hz networks with rated voltages from 400V to 690V. Featuring a 1250A current rating and 4-pole (4P) configuration, it incorporates electric quick-action mechanism and plug-in mounting, compatible with AC220V control voltage. Its core functions include power distribution, line protection, and overload/short-circuit prevention for power equipment, with additional capability for infrequent circuit switching. The modular design utilizes silver-alloy main contacts for optimal conductivity, while the arc-extinguishing system ensures effective fault current interruption. The withdrawable structure facilitates maintenance, with panel-mounted status indicators and manual operation buttons, supporting various electrical accessories for functional expansion.5617
技術特點（中英文）
該斷路器采用三維立體布局設計，接觸系統(tǒng)與脫扣機構分離安裝，提升操作穩(wěn)定性。電動快速操作機構響應時間小于50ms，預儲能功能可減少80%合閘能耗。抽屜座采用鍍鎳銅合金導軌，插拔壽命超過500次，并配備機械聯(lián)鎖防止誤操作。內(nèi)部集成電流互感器和電壓變換器，實時監(jiān)測線路參數(shù)。外殼采用阻燃工程塑料，防護等級達IP40。The breaker adopts 3D layout design with isolated contact and trip systems for operational stability. The electric quick-action mechanism responds within 50ms, while pre-charging function reduces 80% closing energy consumption. Nickel-plated copper alloy rails in the withdrawable base ensure 500+ plugging cycles, complemented by mechanical interlock against misoperation. Built-in current transformers and voltage converters enable real-time line monitoring. Flame-retardant engineering plastic housing provides IP40 protection level.61012
應用場景（中英文）
適用于工業(yè)配電系統(tǒng)的主干線路保護，如冶金、化工、數(shù)據(jù)中心等領域的低壓配電柜。特別適合需要遠程控制的場合，可通過PLC或SCADA系統(tǒng)實現(xiàn)自動化管理。插入式結構使其成為應急電源切換、設備檢修維護的理想選擇。典型應用包括電動機保護、變壓器二次側保護及大容量負載分配。Ideal for main circuit protection in industrial power systems such as LV switchgear for metallurgy, chemical plants, and data centers. Particularly suited for remote-controlled applications via PLC/SCADA systems. The plug-in design makes it perfect for emergency power switching and equipment maintenance. Typical applications include motor protection, transformer secondary-side protection, and high-capacity load distribution.1216
操作與維護（中英文）
操作時需通過面板按鈕或外部信號觸發(fā)電動機構，儲能完成后自動執(zhí)行分合閘。定期檢查觸點磨損程度和機構潤滑狀態(tài)，建議每5000次操作或每年進行專業(yè)維護。抽屜單元抽出前必須確認斷路器處于分閘狀態(tài)，導軌接觸面需保持清潔。維護時可單獨測試脫扣特性而不影響主電路。Operation requires triggering the electric mechanism via panel buttons or external signals, with automatic switching after energy storage. Regularly inspect contact wear and mechanism lubrication, recommending professional maintenance every 5,000 operations or annually. Ensure breaker is open before withdrawing the unit, keeping rail contact surfaces clean. Trip characteristics can be tested separately without affecting the main circuit during maintenance.61419
