变(bian)(bian)压(ya)器(qi)(qi)的优(you)点：1、安全可(ke)(ke)靠(kao)：电压(ya)变(bian)(bian)换比(bi)例精(jing)确，余耗特(te)别(bie)低，稳定(ding)性(xing)(xing)好，电流影响小(xiao)(xiao)，对(dui)电网的干扰低，可(ke)(ke)靠(kao)性(xing)(xing)高(gao)。2、适(shi)用性(xing)(xing)强：它具有多功(gong)能(neng)(neng)，可(ke)(ke)靠(kao)性(xing)(xing)高(gao)，能(neng)(neng)在各种恶劣条件下长期运(yun)行不(bu)间断。3、尺(chi)寸小(xiao)(xiao)：它的尺(chi)寸小(xiao)(xiao)，比(bi)较(jiao)传统的变(bian)(bian)压(ya)器(qi)(qi)小(xiao)(xiao)太多，结构紧(jin)凑(cou)，便(bian)于(yu)(yu)运(yun)输，搬运(yun)和(he)(he)安装。变(bian)(bian)压(ya)器(qi)(qi)的缺(que)点：1、价格较(jiao)高(gao)：由(you)于(yu)(yu)其(qi)具有特(te)殊功(gong)能(neng)(neng)，结构复杂(za)，外部保(bao)护要求高(gao)，因此价格较(jiao)高(gao)。2、寿命不(bu)长：由(you)于(yu)(yu)其(qi)结构复杂(za)，功(gong)能(neng)(neng)实现(xian)技术(shu)和(he)(he)装配过程复杂(za)，其(qi)使用寿命相对(dui)较(jiao)短。3、运(yun)转噪音较(jiao)大：变(bian)(bian)压(ya)器(qi)(qi)中(zhong)的某些齿(chi)轮运(yun)转噪音较(jiao)大，会影响电力设备运(yun)行环(huan)境(jing)。变(bian)(bian)压(ya)器(qi)(qi)可(ke)(ke)以(yi)实现(xian)电力系统的节能(neng)(neng)和(he)(he)环(huan)保(bao)，减少能(neng)(neng)源消耗和(he)(he)污染排放。浙江灌封变(bian)(bian)压(ya)器(qi)(qi)工(gong)厂直销
