<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">“第三轨”供电</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">“第三轨”供电，简单地说，<span style="color: black;">便是</span>从地上取电。这条轨道是接触轨，是承载<span style="color: black;">轻轨</span>列车两条轨道之外的第3条轨道。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">车辆<span style="color: black;">经过</span>集电<span style="color: black;">安装</span>与接触轨接触取电，接触轨外设有防护罩<span style="color: black;">保证</span>安全。<span style="color: black;">按照</span>接触面的位置<span style="color: black;">区别</span>，可分为上部授流、下部授流和侧部授流接触轨。</p><img src="https://mmbiz.qpic.cn/mmbiz_png/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMwE6N1WCTFO5rm5EeOhHVRVKPmWDWkUHSH2WVxr9PyZXicpBcOyQJIxNQ/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">日前</span>，接触轨供电多采用750伏电压，<span style="color: black;">亦</span>有部分采用1500伏电压。<span style="color: black;">例如</span>广州<span style="color: black;">轻轨</span>4号线<span style="color: black;">便是</span><span style="color: black;">第1</span>个采用1500伏直流接触轨供电的<span style="color: black;">轻轨</span>。</p><img src="https://mmbiz.qpic.cn/mmbiz_png/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMwpvUWIRuFOmFQxzufROdxTfDicHyeVWkY44iaiaHo971Br5kOJBenY493Q/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">架空接触网供电</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这个就和高铁比较<span style="color: black;">类似</span>了，<span style="color: black;">轻轨</span>隧道上方架设刚性或弹性<span style="color: black;">安装</span>、悬挂接触网，车辆<span style="color: black;">经过</span>受电弓从接触线中获取电流，多采用1500伏电压。</p><img src="https://mmbiz.qpic.cn/mmbiz_png/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMwianzfPfKsXVWaGupiaiahjQnicOnv8D0x76pA9Ok8icTKtLqE5DA4kpDzCA/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">既然有两种供电形式，我相信<span style="color: black;">非常多</span>小伙伴还是会好奇<span style="color: black;">哪种形式更好用？</span>那就继续往下看吧。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">哪种供电方式更佳？</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">安全问题</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">架空接触网是在列车的上方，<span style="color: black;">通常</span>乘客接触到的可能性很小，安全性还是相当高的；而接触轨就不<span style="color: black;">同样</span>了，<span style="color: black;">由于</span>接触轨铺在地面上，即便有防护罩，<span style="color: black;">亦</span>不排除有人掉落触电的可能；<span style="color: black;">倘若</span>有导电性较好的物品掉下，还可能会<span style="color: black;">导致</span>短路现象。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">例如</span>：深圳<span style="color: black;">轻轨</span>3号线就曾<span style="color: black;">出现</span>过乘客雨伞掉落在接触轨上，造<span style="color: black;">成为了</span>10分钟短路事故。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">稳定问题</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">轻轨</span>高速行驶时，接触轨式供电会<span style="color: black;">引起</span>集电<span style="color: black;">安装</span>难以<span style="color: black;">连续</span>抓紧第三轨，<span style="color: black;">由于</span>受流不稳定<span style="color: black;">从而</span>影响行车最高时速，<span style="color: black;">亦</span>不适合大运量的<span style="color: black;">轻轨</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">不外</span>，在<span style="color: black;">卑劣</span>天气下，<span style="color: black;">由于</span>接触轨设有防护罩，受到<span style="color: black;">卑劣</span>天气的影响就比较小。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">成本问题</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">接触轨施工难度较小、建设成本相对低；而架空接触网建设成本和施工难度就高上<span style="color: black;">非常多</span>。<span style="color: black;">况且</span>架空接触网局部易磨损，<span style="color: black;">守护</span>工作量更大。</p><img src="https://mmbiz.qpic.cn/mmbiz_gif/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMwrPlzf3B0mkQvzTZichKDicaJWzmcSncfXFDQKxIxpngycJEVLgdUmuyg/640?wx_fmt=gif&tp=webp&wxfrom=5&wx_lazy=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMwmh6ickqJ1YlibFK6Gc0h6VkKS9DoCGVgB3vRTxHB6PL3DyKoakf01vgw/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMweMEZ49x308BFCibK22HxvgL5l99eicbaibQZ51icMjCotBxQziaAIk91JPg/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因此</span>说，即便架空接触网有更安全、<span style="color: black;">轻轨</span>行车速度更快、运载量更大等优点，接触轨<span style="color: black;">亦</span>是有其存在<span style="color: black;">恰当</span>性的。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">由于</span>，<span style="color: black;">轻轨</span>采用哪种供电方式，要<span style="color: black;">思虑</span><strong style="color: blue;"><span style="color: black;">城市特点、客流<span style="color: black;">体积</span>、列车编组、美观<span style="color: black;">需要</span></span></strong>等各方面<span style="color: black;">原因</span>。</p><img src="https://mmbiz.qpic.cn/mmbiz_jpg/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMw2qLmylVTKGib9Ffgzib5GcW1icWxW2TG5elvDHBjXtCZ2GsKVibAqnjDLg/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/HKWtUAzicyRumUdtiagyEzTZMAv6uxMeMwia1AbLwiaSCE3SOwo4tUjeUqI1yDiaSe3MHVumTCbafkdEYjNbpWfrD1A/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">顺便一提，就算是接触轨式供电，国内<span style="color: black;">轻轨</span><span style="color: black;">亦</span>是<span style="color: black;">不易</span>触电的，<span style="color: black;">由于</span><span style="color: black;">咱们</span>有<strong style="color: blue;">屏蔽门</strong>，<span style="color: black;">因此</span>人掉下<span style="color: black;">轻轨</span>轨道的可能性是很小的。</p>
