  改變運行方式,合理調度變壓器的運行容量。為提高供電可靠性和電網安全性,通常在變電站內安裝兩臺同容量、同型號的變壓器并聯運行。當一臺發生故障或檢修時,另一臺保持供電。在變壓器負荷輕載時,如并聯運行的變壓器臺數不變,則繞組中電阻損耗很小,但鐵芯損耗所占比例較大。這時在不使部分變壓器過負荷的情況下,可以切除一部分變壓器,減少變壓器的總損耗。縣級電網由于受運行方式、系統短路容量及保護選擇的影響,一般不允許變壓器并列運行,但從經濟方式上考慮,在保證電網安全的情況下,變壓器并列運行不失為一中有效“節電”途徑

  長期以來人們僅以變壓器的容量利用率作為劃分變壓器“大馬拉小車”的唯一標準。縣級電網企業管理人員很少考慮主變“容載比”,加上我國有的節電措施ZHONGGUIDINGBIANYAQIDEFUZAILVXIAOYU30%JIWEI“DAMALAXIAOCHE”,♉ZAIYOUXIEDIFANGYI40%HUO50%WEIHUAFENJIEXIAN。ZHEYANGJIUHUIDAOZHIZAIMOUXIETIAOJIANXIAYIXIAORONGLIANGBIANYAQIHUANDIAODARONGLIANGBIANYAQI,QIJIEGUOBUJINBUJIEDIANFANERLANGFEILEDIANLI。

  二、加強日常用電管理

  變電站的照明是站內損耗的主要指標,長期以來對變電站長明燈缺乏有效的監督和治理,時常造成燈炮越換越大,損耗越來越多。因此,必須因地制宜,充分有效地采用自然光,正確合理地選用高效節能光源,提高照明利用率,以期獲得最大的社會效益和經濟效益。變電站的照明用電占用電量的1/2以上,變電站內照明是主要損耗,積極推廣“綠色照明”采用智能燈光凯发k8官网app和電器附件是變電站節電工作的主要內容。根據變電站各工作場所選擇合理的照度、良好的顯色性、相宜的色溫、較小的眩光、舒適的亮度比,合理確定光源、燈具。在變電站更換節能型燈具、定時、聲控、光控開關,安裝凯发k8官网app,在后半夜將燈照度降低。對主控室、值班室的空調加裝凯发k8官网app、DIANNUANQI,GEZHONGSF6KAIGUANJIAREZHUANGZHI、HUANQIZHUANGZHIBIXUANGUIDINGDERIQI、JIEHEWEN♌DUYUNXINGJINXINGTOU、TING。DUIYUNXINGZHONGFENGLENGQUEZHUBIANYAQIYINGJIAQIANGJIANSHI,JISHITOUTINGFENGSHAN。GENJUJIJIEQINGKUANGTUICHIKAIDENGSHIJIAN,JIUKEYIJIESHENGDALIANGDIAN🐬NENG,JIANGSHINEI、SHIWAIZHAOMINGDENGJITANZHAODENGDOUGENGHUANWEI“SANJISEJIENENGDENG、JINSHULUHUAWUDENG” LIYONGQIGAOGUANGXIAO、GAOLIANGDU、GAOXIANSEXING、DUOSEDIAO、CHANGSHOUMINGDETEDIAN,JIANGZHENLIUQIGENGHUANWEIJIENENGXINGDEDIANZIZHENLIUQI,DUIDENGJUDEPAILIEYUBUZHIJINXINGJISUANJIYOUHUA,DUISHIWAITANZHAODENGJUJINXINGZHONGXINANZHUANG,SHIQIZHAOSHEYUAN、FUGAIMIANDA,ZHAODUJUNYUN、XUANGUANGXIAO,NENGMANZUQIANGXIUANQUANDESHIJIYAOQIU,TONGSHIZAIZHANNEIBIYAODEDAOLU、SIJIAOANZHUANGXIAOGONGLVDENGPAO,MANZUANQUANYAOQIUHEJIENENGXING。

  三、依靠科技進步

  充分利用變電站大修、技術改造、年檢預試、保護校驗、設備消缺機會,從細微入手對變電站一次設備接頭進行改造采用節能線夾,推廣無噪聲交流接觸器,改造變電站傳統中央信號,高壓開關位置白熾信號燈,都是節能降損有效的技術措施。中央信號,高壓開關位置白熾燈功耗大、易損壞,長期工作造成其溫度升高,塑膠接頭過熱以至損壞燈具。同時燈泡壽命短,經常需要更換,造成直流負荷不必要的增大。為了保證變電站安全運行,降低直流負載,更換為新型微電流閃光和沖擊繼電器以及半導體節能信號燈,節能信號燈和光示牌功耗分別為3.3W和6.6W,只占白熾燈的1/4,功耗低,節能顯著,且使用壽命延長3至4年。JIENENGDENG🌊JUDECAIꦑYONGGAISHANLEZHILIUSHEBEI、XUDIANCHIZHONGFUHEYALI,YEJIANSHAOLEGUIZHENGLIUFUCHONGDIANLIU,TONGSHIJIANSHAOLEJIGAITOUZI,JIANSHAOLEGONGZUORENYUANDEWEIHULIANG,DAFUDUDIJIANGDILENENGHAOHESHENGCHANWEIHUFEIYONG。
