需將旁通柜內開關切換為工頻伎倆，然后合上相應的高壓開關不妨.。軟起動器和變頻器是兩哪類區別用途的產品.變頻器是用于需要調速的地方，其輸出不但變化電壓而且同時變化頻率；軟起動器實際上是個調壓器，用于電機起動時，輸出只變化電壓并沒有變化頻率.變頻器具備整體軟起動器功，但它的價格比軟起動器貴得多，結構也復雜得多.應用串接于電源與被控電機之間的軟起動器，應用其內部晶閘管的導通角，使電機輸進電壓從零以預設函數相關緩緩上升，直至起動結束，賦予電機全電壓，就無妨為軟起動，在軟起動過程中，電機起動轉矩緩緩增添，轉速也緩緩增添.軟起動常常有下面幾哪類起動方法.斜坡升壓軟起動.這哪類起動方法簡單，不具備電流閉環應。二，PLC可編程、工業開關電源、人機界面、DCS卡件及各種控制線路板等工控產品。
