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(wǎng)容量不足的工礦企業(yè)。本產(chǎn)品是通過
機械傳動裝置使串接在電動機定子側(cè)或星點側(cè)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(xiàn)電機的平滑起動。 l 適應(yīng)全負(fù)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(shè)備的使用壽命;l 起動轉(zhuǎn)矩大,不受電網(wǎng)質(zhì)量的影響,起動成功率100%;l 結(jié)構(gòu)緊湊,自動化程度高,安全可靠,故障率低,節(jié)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(shè)備利用率。執(zhí)行標(biāo)準(zhǔn):高壓開關(guān)設(shè)備和控制設(shè)備標(biāo)準(zhǔn)共用技術(shù)要求 GB/T11022-1999 IEC60694∶1996 3-35kV交流金屬封閉開關(guān)設(shè)備 GB3906-2006 IEC298∶1990 水電阻起動器 Q/XDY02-2005 Applicabletosoftstartandprotectionoflargeandmedium-sizedcage-modeasynchronousmotororsynchronousmotorofthree-phase50Hz,ratedvoltage3kV-10kV,inparticularfortheindustrialandminingenterpriseswithinadequatecapacityofthepowergrids.
