一、頻敏柜概述

頻敏(min)起(qi)(qi)動(dong)(dong)(dong)柜適用于交流50HZ，電(dian)壓380V,轉子電(dian)流600A及(ji)以(yi)下的(de)三相繞(rao)線型異步電(dian)動(dong)(dong)(dong)機(ji)的(de)起(qi)(qi)動(dong)(dong)(dong)、停(ting)止及(ji)運行(xing)控制，用于不(bu)頻繁的(de)操作、可逆、不(bu)調速和不(bu)要求(qiu)制動(dong)(dong)(dong)的(de)三相繞(rao)線型異步電(dian)動(dong)(dong)(dong)機(ji)的(de)起(qi)(qi)動(dong)(dong)(dong)控制，利用頻敏(min)變阻器(qi)阻抗(kang)限(xian)制起(qi)(qi)動(dong)(dong)(dong)電(dian)流，可以(yi)自由調節起(qi)(qi)動(dong)(dong)(dong)時間，頻敏(min)變阻器(qi)一般均備有(you)調節抽頭，以(yi)適應(ying)各種不(bu)同情況下電(dian)機(ji)起(qi)(qi)動(dong)(dong)(dong)用從(cong)而減少對輸電(dian)網絡系統的(de)影(ying)響(xiang)，對電(dian)動(dong)(dong)(dong)機(ji)具有(you)短路及(ji)過載保(bao)護作用。

二、性能特點

本系列(lie)產(chan)品(pin) 為(wei)柜式防護結(jie)構，由(you)頻敏變阻(zu)器(qi)(qi)，自動(dong)(dong)開(kai)關、交流接(jie)觸器(qi)(qi)、熱繼電(dian)器(qi)(qi)和(he)時間繼電(dian)器(qi)(qi)等(deng)主要元件組成，控制柜前(qian)后開(kai)門，并且有(you)電(dian)流顯示(shi)信(xin)號燈及(ji)控制按鈕等(deng)。時間繼電(dian)器(qi)(qi)為(wei)可(ke)(ke)調式，可(ke)(ke)以自由(you)調節起動(dong)(dong)時間，頻敏變阻(zu)器(qi)(qi)一般均備有(you)調節抽頭，以適應各種不同情況下電(dian)機起動(dong)(dong)用。對(dui)電(dian)動(dong)(dong)機具(ju)有(you)短路及(ji)過載保護。
