力(li)电(dian)容(rong)器(qi)，是电(dian)网(wang)中(zhong)常见(jian)的用电(dian)设备。通常，我们(men)会把并(bing)联(lian)在(zai)母线上的电(dian)容(rong)器(qi)，称为并(bing)联(lian)电(dian)力(li)电(dian)容(rong)器(qi)。那并(bing)联(lian)电(dian)力(li)电(dian)容(rong)器(qi)在(zai)电(dian)网(wang)中(zhong)，起到了(le)什么作用呢？并(bing)联(lian)电(dian)力(li)电(dian)容(rong)器(qi)安装时，又有哪些注意事项？

1、电容器的并联

并(bing)联电(dian)力电(dian)容(rong)器(qi)(qi)，属于容(rong)性(xing)负(fu)(fu)载(zai)(zai)(zai)设(she)备(bei)；电(dian)动机和变压器(qi)(qi)，属于感性(xing)负(fu)(fu)载(zai)(zai)(zai)设(she)备(bei)。如果把容(rong)性(xing)负(fu)(fu)载(zai)(zai)(zai)设(she)备(bei)并(bing)联在感性(xing)负(fu)(fu)载(zai)(zai)(zai)设(she)备(bei)上，感性(xing)负(fu)(fu)载(zai)(zai)(zai)设(she)备(bei)需要(yao)的(de)无功(gong)，将(jiang)会由容(rong)性(xing)负(fu)(fu)载(zai)(zai)(zai)设(she)备(bei)提(ti)供(gong)。这样可以(yi)(yi)提(ti)升(sheng)发(fa)电(dian)设(she)备(bei)的(de)工作效率(lv)，降低变压器(qi)(qi)和输电(dian)线路的(de)无功(gong)损(sun)耗，同时可以(yi)(yi)提(ti)高企业(ye)功(gong)率(lv)因(yin)数，改善电(dian)网电(dian)能质(zhi)量。

2、安装(zhuang)电容器的注意事项

①电(dian)容器的接线**采用(yong)单独的软线与(yu)母线相连(lian)，防止并联电(dian)力电(dian)容器套管损坏破坏密封，进而(er)引起电(dian)容器漏(lou)油。

②安(an)装并联电力电容(rong)器时(shi)，要(yao)保持其相间平(ping)衡，偏差(cha)不超过总容(rong)量(liang)的5%。

③电容器(qi)应(ying)(ying)安装(zhuang)(zhuang)在无(wu)腐蚀性(xing)气体、无(wu)蒸汽、无(wu)剧烈震动、冲击、爆炸、易燃等场所；装(zhuang)(zhuang)于户外(wai)的电容器(qi)应(ying)(ying)防止日(ri)光直接照射。

④配电(dian)(dian)(dian)室的环境温(wen)度，应满(man)足(zu)电(dian)(dian)(dian)力电(dian)(dian)(dian)容器(qi)厂家规定的要求；在电(dian)(dian)(dian)容器(qi)室装设通(tong)风(feng)机(ji)时，出风(feng)口应安装在电(dian)(dian)(dian)容器(qi)组的上(shang)端；配电(dian)(dian)(dian)室可(ke)采(cai)用天然(ran)采(cai)光，也(ye)可(ke)用人(ren)工照明，不需(xu)要装设采(cai)暖装置。

在企(qi)业的(de)供电(dian)(dian)系统(tong)中(zhong)，并联(lian)电(dian)(dian)力电(dian)(dian)容(rong)(rong)器非常重要(yao)。并联(lian)电(dian)(dian)力电(dian)(dian)容(rong)(rong)器的(de)运行状态，对企(qi)业电(dian)(dian)网影响很大，因此需要(yao)按照规定(ding)安装(zhuang)电(dian)(dian)容(rong)(rong)器，降低(di)其故障率。
