font-size: 14px;">一、高温对设备运行的影响</span></strong></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">LCT2901C 485总线温湿度传感器</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">LCT2901DU USB接口温湿传感器</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">(1)温度与平均无故障运行时间的关系——10℃法则</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">由于现代电子设备所用的电子元器件的密度越来越高,使元器件之间通过传导、辐射和对流产生热耦合。因此,热应力已经成为影响电子元器件时效的一个最重要的因素。对于某些电路来说,可靠性几乎完全取决于热环境。为了达到与其的可靠性目的,必须将元器件的温度降低到实际可以达到的最低水平。有资料表明:环境温度每提高10℃,元器件寿命约降低30%-50%,影响小的也基本都在10%以上,这就是有名的“10℃”法则。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">(2)高温对元器件的影响</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">A、半导体器件。电子元器件在工作时产生大量的热,如果没有有效的措施及时把热三走,就会使集成电路和晶体管等半导体器件形成结晶,这种结晶是直接影响计算机性能、工作特性和可靠性的重要因素。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">根据实验得知,室温在规定范围内每增加10℃,其可靠性约下降25%。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">器件周围的环境大约超过60℃时,就将引起计算机发生故障,当半导体期间的温度过高时,其穿透电流和电流倍数就会增大。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">B、电容器。温度对电容器的影响主要是:使电解电容器电解质中的水份蒸发增大,降低其容量,缩短其使用寿命,改变电容器的介质损耗,影响其功率因数等参数变化。由实验得知,在超过规定温度工作时,温度每增加10℃,其使用时间下降50%。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">C、记录介质。实验表明:当磁带、磁盘、光盘所处温度持续高于37.8℃时,开始出现损坏;当温度持续高于65.6℃时则完全损坏。对于磁介质来说,随着温度的升高,磁导率增大;当温度达到某一个值时,磁介质丢失磁性,磁导率急剧下降。磁性材料失去磁性的温度称为居里温度。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">D、绝缘材料。由于高温的影响,用玻璃纤维胶板制成的印制电路板将发生变形甚至软化,结构强度变弱,印制板上的铜箔也会由于高温的影响而使粘贴强度降低甚至剥落,高温还会加速印制插头和插座金属簧卡的腐蚀,使接点的接触电阻增加。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">E、电池环境温度与寿命的关系。电池是对环境温度最敏感的器件(设备),温度在工作温度25℃的基础上,每上升10℃,寿命下降50%。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">三、低温对IT设备运行的影响</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">低温同样导致IT设备运行、绝缘材料、电池等问题。当机房温度过低时,部分IT设备将无法正常运行。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">(1)机房温度过低导致设备无法运行</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">机房的环境温度低于5℃时,通信设备将无法正常运行;机房的环境温度低于-40℃时,铅酸电池无法提供能量。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">(2)绝缘材料</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">低温时,绝缘材料会变硬、变脆,使结构强度同样减弱。对于轴承和机械传动部分,由于其自身所带的润滑油受冷凝结,黏度增大而出现黏滞现象。温度过低时,含锡量高的焊剂会发生支解,从而降低电气连接的强度,甚至出现脱焊、短路等故障。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">(3)电池环境温度与放电容量的关系</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">同样,当工作温度为25℃之下时,随着温度的下降,电池放电容量下降。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">一、湿度对IT类设备运行的影响</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">通常,IT类设备的工作环境要求湿度为40%-55%。超过65%的湿度,为湿度过高;超过80%属于潮湿;低于40%术语湿度过低(空气干燥)。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">(1)湿度过高对IT类设备运行的影响</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">当空气的相对湿度大于65%时,物体的表面附着一层厚度为0.001-0.01μm的水膜;湿度为100%时,水膜厚度为10μm。这样的水膜容易造成“导电小路”或者飞弧,会严重降低电路可靠性。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">在相对湿度保持不变的情况下,温度越高,对设备的影响越大,这是因为水蒸气压力随温度升高而增大,水分子易于进入材料内部。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">当相对湿度由25%增加到85%时,纸张的厚度将增加80%,这就是在潮湿的天气里打印机无法正常工作的原因。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">(2)湿度过低对IT类设备运行的影响</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">静电放电是电子工业中的曾普遍存在的“硬病毒”,在内、外因条件具备的特定时刻便会发作,已成为电子工业的隐形杀手。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">据报道,仅美国电子工业每年因静电放电造成的损失就达几百亿美元。根据Intel公司公布的资料显示,在引起计算机故障的诸多因素中,电气过应力(ElectricalOverStree,EOS)/ESD是最大的隐患,将近一半的计算机故障都是由EOS/EDS引起的,ESD对计算机的破坏作用具有隐蔽性、潜在性、随机性和复杂性的特点。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">IT类设备由众多芯片、元器件组成,这些元器件对静电都很敏感,不同的静电敏感器件受静电损伤的阈值电压不同。在空气湿度过低时,工作人员的活动非常容易产生静电电压。</span></p><p style="line-height: 2em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;; font-size: 14px;">实验表明,当机房相对湿度为30%时,静电电压为5000v;当机房相对湿度为20%时,静电电压为10000v;当机房相对湿度为5%时,静电电压可高达20000v以上。这足以表明湿度对运行中的IT设备的重要性。</span></p><p><br/></p>', 'author' => '北京长信物联科技有限公司-miya', 'author_role' => '1', 'theme' => 'info_theme_new', 'page_view' => '9567', 'jump_url' => null, 'price' => null, 'original_price' => null, 'set_time_out' => null, 'sale' => '0', 'file' => null, 'extend_1' => null, 'extend_2' => null, 'extend_3' => null, 'extend_4' => null, 'extend_5' => null, 'extend_6' => null, 'extend_7' => null, 'extend_8' => null, 'extend_9' => null, 'created_at' => '2018-09-18 19:28:04', 'updated_at' => '2024-03-29 16:15:57', 'deleted_at' => null, 'time' => '2018-09-18 19:28:04', 'sorts' => array(array('url' => 'newlist_63.html', 'name' => '解决方案')), 'filesize' => '4 KB'), 'frames' => array(array('url' => 'http://www.lct2000.cn/index_aaab.html', 'name' => '首页'), array('url' => 'http://www.lct2000.cn/aaab/newlist.html', 'name' => '新闻中心'), array('url' => '', 'name' => '机房温湿度...'))), 'sorts' => array(array('url' => 'newlist_63.html', 'name' => '解决方案')), 'tmpImages' => array())) in InfoController.php line 68
