產(chǎn)品詳情
FR - HCR2 - H560K 是三菱電機專為大功率工業(yè)電力系統(tǒng)打造的限流電阻，常配套 FR - HC2 系列高功率因數(shù)變流器使用，核心作用是抑制設備啟動時的浪涌電流，保障大功率變流系統(tǒng)穩(wěn)定啟動與運行，廣泛適配鋼鐵、化工、重型機械等領域的 560kW 級大功率設備供電系統(tǒng)。以下是其超千字的詳細介紹：
-
核心基礎參數(shù)與物理特性
- 適配功率與電氣適配性：該器件專為 560kW 級大功率場景設計，匹配三菱 FR - HC2 - H560K 等高功率因數(shù)變流器，是對應功率等級變流系統(tǒng)的核心配套部件。其適配的電力系統(tǒng)為三相 400V 級，可兼容 380 - 500V 的寬電壓輸入范圍，能應對工業(yè)電網(wǎng)中常見的電壓波動，適配 50/60Hz 通用工頻標準，無需因地域電網(wǎng)頻率差異進行額外調(diào)整，適配全球多數(shù)工業(yè)用電場景。從系統(tǒng)協(xié)同性來看，它與同功率等級的整流單元、濾波電容等部件電氣參數(shù)高度匹配，可無縫融入大功率共直流母線系統(tǒng)。
- 結(jié)構(gòu)與安裝規(guī)格：該限流電阻有帶溫控器（BKO - CA1996H31）和不帶溫控器（BKO - CA1996H21）兩種版本，基板厚度均為 2.5mm，這種基板規(guī)格既能保證結(jié)構(gòu)強度，又能滿足散熱需求。安裝方面，手冊明確要求需用螺釘或螺栓將其牢固安裝在水平或垂直平面上，防止設備運行中的振動導致松動，保障電路連接穩(wěn)定性。其外形尺寸與同系列 H280K、H400K 等型號保持設計一致性，方便成套設備的標準化安裝與布局，且可與 FR - HCC2 系列濾波電容、FR - HCL2 系列電抗器等部件按固定接線規(guī)范組合安裝，簡化了成套系統(tǒng)的布線流程。

核心功能與工作原理
- 浪涌電流抑制核心作用：工業(yè)大功率變流系統(tǒng)啟動時，電容等儲能元件會產(chǎn)生瞬時超大浪涌電流，極易燒毀整流橋、電容等核心元器件。FR - HCR2 - H560K 通過自身電阻特性，在系統(tǒng)啟動瞬間接入電路，限制充電電流的上升速率，大幅降低浪涌電流峰值。待系統(tǒng)完成啟動、母線電壓穩(wěn)定后，電路中的接觸器會將該限流電阻短接，避免其長期工作產(chǎn)生能耗與損耗，既實現(xiàn)了啟動保護，又不影響系統(tǒng)正常運行效率。這種 “啟動接入，穩(wěn)態(tài)斷開” 的工作模式，是大功率變流系統(tǒng)延長使用壽命的關鍵保障。
- 與系統(tǒng)協(xié)同的輔助功能：它可配合 FR - HC2 系列變流器實現(xiàn)共直流母線系統(tǒng)的穩(wěn)定運行。在多臺變頻器共用直流母線的場景中，多臺設備同時啟停時的電流沖擊更為復雜，該限流電阻能協(xié)同多組濾波電容、電抗器，均衡各支路啟動電流，防止單支路電流過大破壞系統(tǒng)平衡。同時，帶溫控器的版本可實時監(jiān)測電阻工作溫度，當出現(xiàn)異常過熱情況時，能及時觸發(fā)保護信號，與系統(tǒng)的整體保護機制聯(lián)動，避免因電阻過熱引發(fā)火災等安全隱患，進一步提升了系統(tǒng)的安全冗余。此外，它還能輔助改善系統(tǒng)的電磁兼容性，減少啟動時電流突變產(chǎn)生的電磁干擾，保障周邊控制電路的穩(wěn)定工作。

性能優(yōu)勢與可靠性設計
- 高適配性與兼容性：該型號屬于 FR - HCR2 系列，該系列包含 H280K、H400K、H560K 等多個功率等級型號，各型號在安裝接口、控制邏輯上保持統(tǒng)一標準，方便用戶根據(jù)設備功率升級或降級時進行部件替換。其不僅適配三菱自有品牌的變流系統(tǒng)，在符合電氣規(guī)范的前提下，也可與其他品牌同參數(shù)等級的大功率變流器配套使用，兼容性較強。同時，它能適配持續(xù)再生運行等復雜工況，比如流水線、起重設備等頻繁啟停的場景，可反復承受啟動時的電流沖擊，性能穩(wěn)定性不受工況復雜度影響。
- 強環(huán)境適應與長壽命設計：作為工業(yè)級部件，其采用耐高溫、耐腐蝕的電阻材料與基板材質(zhì)，可適應工業(yè)車間常見的粉塵、潮濕等環(huán)境。搭配變流系統(tǒng)的強制通風冷卻方式，能有效散除啟動時產(chǎn)生的瞬時熱量，避免高溫積累導致的電阻老化。從系統(tǒng)壽命協(xié)同性來看，其設計壽命與 FR - HC2 系列變流器匹配度高，減少了成套設備中因單一部件提前損壞導致的頻繁停機維護。此外，其電路連接點經(jīng)過強化處理，能抵抗工業(yè)環(huán)境中的振動與電磁侵蝕，降低接觸不良等故障風險。

-
系統(tǒng)集成與應用場景
- 標準化系統(tǒng)集成方案：在實際應用中，它需按固定接線規(guī)范融入系統(tǒng)，通常安裝在電抗器 1 的輸出側(cè)或限流接觸器的輸入側(cè)，與濾波電容、電抗器等部件構(gòu)成完整的前端保護電路。接線時需注意與報警檢測器的常閉觸點、緩沖繼電器等元件聯(lián)動，確保異常情況下能及時切斷電路。系統(tǒng)中還可通過參數(shù) Pr.32 查看限流電路中繼電器、接觸器及該限流電阻的使用壽命，便于提前規(guī)劃維護，減少突發(fā)故障。
- 多元化工業(yè)應用場景：在鋼鐵行業(yè)，它可配套大功率變流器用于軋鋼機、連鑄機等設備的供電系統(tǒng)，這些設備啟動時功率需求極大，該限流電阻能保障供電系統(tǒng)穩(wěn)定啟動，避免因電流沖擊導致生產(chǎn)中斷；在重型機械領域，如礦山提升機、港口起重機等，設備頻繁啟停產(chǎn)生的浪涌電流危害顯著，該部件可有效延長其供電系統(tǒng)的使用壽命。此外，在化工行業(yè)的大型壓縮機、水泥行業(yè)的回轉(zhuǎn)窯驅(qū)動系統(tǒng)等大功率設備中，它也是保障成套電氣設備安全運行的關鍵配套部件，助力這些行業(yè)實現(xiàn)連續(xù)、穩(wěn)定的工業(yè)化生產(chǎn)。
-
維護要點與安全規(guī)范
- 日常維護與檢測：日常需定期檢查其安裝固件是否松動，基板有無變形、灼燒痕跡，接線端子是否氧化、松動。對于帶溫控器的版本，要檢測溫控信號傳輸是否正常，確保過熱時能及時觸發(fā)保護。結(jié)合系統(tǒng)參數(shù) Pr.32 的壽命提示，當接近使用壽命閾值時，需提前采購備件進行更換。同時，要保持其安裝區(qū)域的通風通暢，避免粉塵堆積影響散熱。
- 安全操作規(guī)范：安裝與更換時必須切斷上級電源，并等待母線電容完全放電，防止觸電風險。嚴禁將易燃物放置在該電阻附近，因其啟動時會產(chǎn)生瞬時熱量，若接觸易燃物可能引發(fā)安全事故。此外，非專業(yè)人員不得擅自更改其接線方式或拆卸部件，維修需由具備資質(zhì)的技術人員按手冊規(guī)范操作，避免因操作不當損壞整個變流系統(tǒng)。
