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)的兩較板在水電阻中平滑移動,電阻值由較大無級減少直至趨于零,達(dá)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**;
l 結(jié)構(gòu)緊湊,自動化程度高,***,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。

水電阻起動器 Q/XDY02-2005
Applicable to soft start and protection of large and medium-sized cage-mode asynchronous motor or synchronous motor of three-phase 50 Hz,rated voltage 3 kV-10kV, in particular for the industrial and mining enterprises with inadequate capacity of the power grids.
This product can make the bipolar plates connected in series beside the stator andasterism cabinetof the motor move smoothly bymechanical transmission device,and resistance value from the largest to the least(zero)for the purpose of changing the resistance value uniformly and making the motor start smoothly.
