电容补偿柜

产品定义：

电力(li)系(xi)统(tong)中(zhong)的负载类(lei)型大部分属于感(gan)性负载，加上用(yong)电企业(ye)普(pu)遍广泛(fan)地使用(yong)电力(li)电子设(she)(she)备(bei)，使电网功(gong)率(lv)因数较(jiao)低(di)(di)(di)。较(jiao)低(di)(di)(di)的功(gong)率(lv)因数降低(di)(di)(di)了(le)设(she)(she)备(bei)利(li)用(yong)率(lv)，增加了(le)供电投资，损害了(le)电压质量(liang)，降低(di)(di)(di)了(le)设(she)(she)备(bei)使用(yong)寿命，大大增加了(le)线路损耗。故通过在电力(li)系(xi)统(tong)中(zhong)连入电容补(bu)偿柜，可以(yi)平衡感(gan)性负载，提(ti)(ti)高功(gong)率(lv)因数，以(yi)提(ti)(ti)升(sheng)设(she)(she)备(bei)的利(li)用(yong)率(lv)。

产品结构

一(yi)(yi)般来说(shuo)，低(di)压电(dian)(dian)容(rong)(rong)补偿(chang)柜由柜体、母排、熔断(duan)(duan)器(qi)、隔(ge)离开关熔断(duan)(duan)器(qi)组、电(dian)(dian)容(rong)(rong)接触器(qi)、避雷器(qi)、电(dian)(dian)容(rong)(rong)器(qi)、电(dian)(dian)抗器(qi)、一(yi)(yi)、二次导线、端子排、功率因(yin)数自动(dong)补偿(chang)控(kong)制装置、盘面仪表等组成。

基本原理

在(zai)实际(ji)电(dian)(dian)(dian)力系统中，大部(bu)分负载为(wei)异步(bu)电(dian)(dian)(dian)动(dong)机。其(qi)等效电(dian)(dian)(dian)路(lu)可看作(zuo)电(dian)(dian)(dian)阻和电(dian)(dian)(dian)感的(de)串联电(dian)(dian)(dian)路(lu)，其(qi)电(dian)(dian)(dian)压(ya)与电(dian)(dian)(dian)流(liu)的(de)相位(wei)差较大，功率因数较低。并联电(dian)(dian)(dian)容器(qi)后，电(dian)(dian)(dian)容器(qi)的(de)电(dian)(dian)(dian)流(liu)将抵消一部(bu)分电(dian)(dian)(dian)感电(dian)(dian)(dian)流(liu)，从而使电(dian)(dian)(dian)感电(dian)(dian)(dian)流(liu)减(jian)小，总电(dian)(dian)(dian)流(liu)随之减(jian)小，电(dian)(dian)(dian)压(ya)与电(dian)(dian)(dian)流(liu)的(de)相位(wei)差变小，使功率因数提高。
