      <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">微型断路器</p>
    </div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">那样</span>,什么是微型断路器呢,<span style="color: black;">咱们</span>土讲讲叫空气开关,样子<span style="color: black;">便是</span>上图所见的,个头不大,宽度都是18mm的整数,<span style="color: black;">因此呢</span>,在<span style="color: black;">选择</span>开关盒的时候,要<span style="color: black;">尤其</span><span style="color: black;">重视</span>需要几个<span style="color: black;">这般</span>的开关。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">世界<span style="color: black;">第1</span>台微型断路器<span style="color: black;">是由于</span>创立 ABB STOTZ <span style="color: black;">机构</span>的 Hugo Stotz 先生在 1923 年发明的。它已具备了今天微型断路器的基本<span style="color: black;">构成</span>部分:<span style="color: black;">守护</span>系统、电接触系统和开关<span style="color: black;">公司</span>等。短路分断能力在 250V 电压下已达到 500A,这项发明技术已于 1924 年在德国进行专利注册,<span style="color: black;">作为</span>世界上<span style="color: black;">第1</span>次有据可查的微型断路器发明。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">微型断路器,英语简<span style="color: black;">叫作</span>MCB(Micro Circuit Breaker/ Miniature Circuit Breaker),是建筑电气终端配电<span style="color: black;">安装</span>引中<span style="color: black;">运用</span>最广泛的一种终端<span style="color: black;">守护</span>电器。用于125A以下的单相、三相的短路、过载、过压等<span style="color: black;">守护</span>,<span style="color: black;">包含</span>单极1P,二极2P、三极3P、四极4P等四种。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">好了,废话不说,<span style="color: black;">咱们</span><span style="color: black;">此刻</span>就来<span style="color: black;">起始</span>解析<span style="color: black;">咱们</span>家里最常用的空气开关吧,里面门道<span style="color: black;">亦</span>挺深的。</p>

      <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">微断正面2</p>
    </div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这是一个最简单的微断正面图,解析如下:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1是品牌标识,这个很重要,选好的品牌质量都比较<span style="color: black;">靠谱</span>,但<span style="color: black;">亦</span>有<span style="color: black;">非常多</span>假冒的,<span style="color: black;">因此</span><span style="color: black;">途径</span>很重要,别被坑了。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2是断路器系列和极数,这个<span style="color: black;">区别</span>的厂家命名<span style="color: black;">区别</span>,<span style="color: black;">再也不</span>赘述。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3是脱扣的特性及额定电流。这个很重要,前面的C<span style="color: black;">暗示</span>C型曲线,<span style="color: black;">通常</span>家用的就选C就行,电动机等动力的要选D曲线。</p>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/499a7fc0717d494b8dd3ebfe2e95f800~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1728816196&amp;x-signature=Rhjg67PoXt4l%2F3EVkKrv8fvOkd8%3D" style="width: 50%; margin-bottom: 20px;">
      <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">曲线说明</p>
    </div>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/a39e3288b7024d21a4826aed3ecd9c0d~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1728816196&amp;x-signature=%2BwRxyz2pB7tZ0a4is6F7dXjBhRk%3D" style="width: 50%; margin-bottom: 20px;">
      <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">时间特性</p>
    </div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4是额定电压,<span style="color: black;">详细</span>如下图<span style="color: black;">选择</span>:</p>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/3d622f43c2ad4786b3d6410c271a8dc9~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1728816196&amp;x-signature=hL%2Fu1hRZcSZ%2Fksu4o9NBJi7d0IY%3D" style="width: 50%; margin-bottom: 20px;"></div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">5是分断能力,这个<span style="color: black;">非常多</span>人不清楚,其实是非常重要的,按理要进行计算,但<span style="color: black;">因为</span>家用处在配电的末端,<span style="color: black;">因此呢</span>基本<span style="color: black;">亦</span>固定化了,<span style="color: black;">例如</span>图一蓝色的为4500A,图二红色的为6000A,显然,图二更好。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">6是限流等级,分三类,</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">1类限流</span></strong><span style="color: black;">:‌I2t<span style="color: black;">准许</span>为一个正弦整半波能量。‌</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">2类限流</span></strong><span style="color: black;">:‌I2t<span style="color: black;">准许</span>为一个正弦整半波能量的1/3。‌</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">3类限流</span></strong><span style="color: black;">:‌I2t<span style="color: black;">准许</span>为一个正弦整半波能量的1/10。‌</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">其中,‌3类限流是最高限流等级,‌可用于为横截面积较小的电缆<span style="color: black;">供给</span><span style="color: black;">守护</span>,‌从而降低安装成本。‌<span style="color: black;">运用</span>3类限流<span style="color: black;">能够</span>为您<span style="color: black;">供给</span>最佳性能。‌在国内外生产的断路器中,‌<span style="color: black;">倘若</span><span style="color: black;">制品</span>的移印在分断能力下方有一个小框,‌里面有标注一个数字3,‌说明它的能量等级为3,‌限流能力较好,‌符合IEC60898标准规定的最高限流等级—3级。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">7是接线图,没什么好说的,上进下出,×<span style="color: black;">暗示</span>断路器符号,|<span style="color: black;">暗示</span>隔离符号。</p>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/d827015e542946a9a0d125ab4473ca3c~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1728816196&amp;x-signature=DC%2FQ1vyVw3eR%2F9ubo%2FNx%2FijvHwg%3D" style="width: 50%; margin-bottom: 20px;"></div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">当然,为了有更好的<span style="color: black;">守护</span>,微断除了<span style="color: black;">以上</span>的过电流<span style="color: black;">守护</span>功能,还发展出了以下两种常用的<span style="color: black;">守护</span>,家庭装修应<span style="color: black;">恰当</span>配置<span style="color: black;">运用</span>。</p>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/17cd85001f9f4eb2b557ab7f0e757c7a~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1728816196&amp;x-signature=atmsR58VdWVio2LtmsfezbCoVz0%3D" style="width: 50%; margin-bottom: 20px;"></div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">一是漏电<span style="color: black;">守护</span>:</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">这个<span style="color: black;">守护</span>对家用开关非常重要,<span style="color: black;">通常</span>家里人体可触及的金属部分,都应该配置这个<span style="color: black;">守护</span>,带这个<span style="color: black;">守护</span>功能的,都会附加一个带T的测试按钮,当然,价格<span style="color: black;">亦</span>贵不少,可不要省这个钱啊,家里的卫生间,厨房、插座都应该<span style="color: black;">选择</span>带这种漏电<span style="color: black;">守护</span>的开关,卫生间的最好用10mA的。</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">二是过欠压<span style="color: black;">守护</span>。它是<span style="color: black;">守护</span>设备的,比上面的漏电<span style="color: black;">守护</span>不重要<span style="color: black;">有些</span>。但<span style="color: black;">此刻</span>有些设备很昂贵的,<span style="color: black;">例如</span>电脑什么的,<span style="color: black;">那样</span><span style="color: black;">倘若</span>电网<span style="color: black;">出现</span>超过275V或<span style="color: black;">小于</span>160V都会自动脱扣,以<span style="color: black;">守护</span>设备。<span style="color: black;">况且</span><span style="color: black;">倘若</span>买的是自恢复,电压正常了会自动恢复,你就<span style="color: black;">不消</span>担心家里的冰箱停电了。</strong></p>
