適用于三相交流50Hz，額定電壓3KV-10KV的大中型鼠籠式異步電動機或同步電動機的軟起動與保護裝置，尤其是電網容量不足的工礦企業。本產品是通過機械傳動裝置使串接在電動機定子側或星點側的兩極板在水電阻中平滑移動，電阻值由最大無級減少直至趨于零，達到均勻改變電阻值的目的，實現電機的平滑起動。 l 適應全負載條件下起動；l 起動電流小，是額定電流的2-3.5倍；l 起動平滑無沖擊，延長主電機及拖動設備的使用壽命；l 起動轉矩大，不受電網質量的影響，起動成功率100%；l 結構緊湊，自動化程度高，安全可靠，故障率低，節省運行及維護費用；l 熱容量大，能在短時間頻繁起動，提高設備利用率。執行標準：高壓開關設備和控制設備標準共用技術要求 GB/T11022-1999 IEC60694∶1996 3-35kV交流金屬封閉開關設備 GB3906-2006 IEC298∶1990 水電阻起動器 Q/XDY02-2005 Applicabletosoftstartandprotectionoflargeandmedium-sizedcage-modeasynchronousmotororsynchronousmotorofthree-phase50Hz,ratedvoltage3kV-10kV,inparticularfortheindustrialandminingenterpriseswithinadequatecapacityofthepowergrids.
