sui着电力行ye的发展,电力设备的xingneng和jie构youliao很大的提高,dui于电力公薺ing詀n全可靠xing问ti尤其突出,当无法及时chu理问ti时,信誉和jing济xiaoyi势必受到yan重影响。要保证设备的可靠xing除liao在设备的设ji、选购、验收、an装籪ang谥衴ange把关wai,在设备蚫ui撕蟮脑诵形じ遣豢珊鍪拥闹匾换贰Ⅻ/span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  变电站(所)内的各类二ci设眆u缂痰缙鳌⒍藌ixiang、配电屏(柜)、保护屏(柜)、kong謕o粒ü瘢ekong屏(柜)、公yong设备屏(柜)等设备由于自身工作特xing的原因在运行guo程中产生电位差和静电会yin向xing的吸附各类尘aiwei粒,不可bi免会吸附大气环境中的灰尘、油污、潮气、盐fen、jin属尘ai、炭渍等污染wubing形成dui积。影响电气pan柜内各组件的正常散热,导zhiwendu异常升高,huai使得电气pan柜内各组件更易吸潮,导zhi绝缘下jiang;更可neng直jie造成电气pan柜内各组件jie触不良,容易在电路板上形成短路或wei电路,可neng造成kongzhi、cekong设备信号丢shi、shi真;在潮shitiao件下这些含you盐、酸、碱xingwu质的污染wu成为电解质,导电xing增强,绝缘电zujiang低,泄漏电流增大,易导zhi短路、电弧、散热不良及设备误动作等shi箂hengⅫ/span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  电力设备在运行guo程中会产生很高的静电xiao应,吸附粉尘、油污等污染wu;遇到气候转为潮shi时,kong气中的水fen与静电所吸竕iang奈廴緒u又产生综合腐蚀。为liao散热而设置的装置如feng扇叶片因高速运动和静电吸附而使各种污染wu积ju,这些jun会yin起设备的软xing故障。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  wen差的变hua以及由此带lai的一系列影响dui二ci设备的危害也是不可忽略的。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  1、使yuan器件表mian的wendu升高。数据表ming,当wendu升高10℃,设备的可靠xingjiang下jiang25%;当wendu继续上升,可neng会jiang耐wenxing较差的yuan器件或者jie线烧坏。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  2、产生静电,当它neng量积累到一ding程du,妨碍它中和的绝缘体再也zu挡不zhu时,即发生剧烈放电,即静电放电(ESD),这时的最高电压可达几千乃zhi几万fu,势必dui静电敏感组件造成sun害;静电放电(ESD)及电气guozai(EOS)dui电ziyuan器件造成sun害的主要ji理you热二ci击穿、jin属镀层熔融、介质击穿、气弧放电、表mian击穿、体击穿等等。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  3、dui设备造成电磁干rao。各种各样的软件故障表现为:不稳ding、乱码、误码等;</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  4、盐污溶于kong气中的水fen,造成电huaxuewei电路,dui设备表mian造成腐蚀。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  5、造成jie触不良,当污染yan重时会造成在线监ceyi器不neng报警糰n籲eng正常工作。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  大气中的盐fen可溶解在设备表mian的水膜内,使水膜成为活xing电解质,腐蚀jin属及无ji材liao,bingdui不同jin属产生电偶腐蚀。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  酸xing气体当酸在yuan器件或设备表mian时,会dui表mian的材liao造成腐蚀(特bie是jin属材liao),造成yuan器件短路或断路或漏电,bing直jie影响到设备的使yongshou命。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  尘ai类固体颗粒这类污染wu的组成较复杂,除盐粒ziwaihuaiyou碳和碳的hua合wu、氮huawu、jin属氧huawu、sha土等。在工ye区出现的尘ai类固体颗粒huai往往包含you大量焦油产wu、灰fen及煤烟,也是尘ai的一bufen。沙石和尖ai是高du吸潮的,落在电ziyuan件的表mian上时,襷i谑蛊鋍hu于潮shi状态。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  </span><strong><span style="font-family:SimSun;font-size:14px;line-height:2;">它们dui设备腐蚀的影响主要you四种fang式:</span></strong> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  1、颗粒本身具you腐蚀xing,溶于jin属表mian的水膜内,使水膜的电导率升高,促进liaojin属的腐蚀。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  2、颗粒本身无腐蚀xing,但neng吸附腐蚀xingwu质,间jie地加速腐蚀。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  3、本身既无腐蚀xing又不具吸附xing,但由于造成毛细管凝ju缝隙,使jin属表mian形成电解液薄膜,形成氧浓差的局bu腐蚀tiao件,也会加速jin属的腐蚀。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  4、吸潮的沙石簍ong綼i的积ju可以po坏电气jie点,妨碍正常的旋转作yong和电极的从动ji构,yin起指示yi表出现故障,这些问ti必ran会使设备发生故障和带laian全feng险。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  环境kongzhi系tong(如kong调)是为liao改善设备的工作tiao件而设ji的,但shi实证ming,送feng系tong往往导zhi更yan重的静电吸附,使其通路的设备上(包kuo电路板上)积ju更duo的尘ai、油污、盐fen、酸xing氧huawu和建zhu粉尘等。这种累积的污染wu令设备散热xingneng变差,尽管ji房wendu正常,但局buwendu会ming显升高,bing使一些设备工作异常,dui设备的正常运行形成liao潜在的危害。虽randui防尘与防潮的设ji问ti作liaoduo种考虑,也采yongliao防尘与防潮的措施,但灰尘与水fen仍会通guo各种意想不礿iang耐緅ing侵入设备。许duo通信设备在设ji时很shao考虑到cao作环境,使排气feng扇进kou管、kong气冷却管和排气kou成为污染wu与水fen侵入的较佳入kou。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  电力二ci设备要构成一个完zheng的系tong,xu要you许duo零bu件,如继电器、jie线端zi、开关、指示deng、导线以及蓌i俑龅缙琷ie器等。在酸xing环境下设备会产生许duo电偶或原电chi,构成zheng个系tong的各种bu件置身于大气环境中,受环境的腐蚀侵袭,因而会产生许duo与综合腐蚀you关的问ti。</span> </p> <p> <span

<span style="font-family:SimSun;font-size:14px;line-height:2;">  1、che底清除各种污染wu,恢复新jixingneng。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  2、jiang低故障率,提高运行质量。</span> </p> <p> <span style="font-family:SimSun;font-size:14px;line-height:2;">  3、jiang低维护费yong,提高jing济xiaoyi。</span> </p> <p> <span
