    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">车厢保险盒去电OK的,<span style="color: black;">由于</span>保险盒是从电瓶直接分线过来的(就在电瓶边上,会看到用100A及以上的保险丝分了好几路到<span style="color: black;">区别</span><span style="color: black;">地区</span>,有一路<span style="color: black;">便是</span>到车厢保险丝盒的,<span style="color: black;">通常</span><span style="color: black;">运用</span>100A的保险),而车厢内各路设备都是从这根主线用<span style="color: black;">区别</span>保险丝再分配出去,而市售的保险丝取电器是和原保险丝并联在主线上的,当然,<span style="color: black;">不可</span>插反,否则<span style="color: black;">便是</span>串联了,若有空的保险丝位置<span style="color: black;">亦</span><span style="color: black;">能够</span>直接用,只插一片保险丝就行了,50W电台<span style="color: black;">通常</span>15A就够了,<span style="color: black;">这般</span>和直接接电瓶是<span style="color: black;">同样</span>的,最好找到ACC继电器的输出,<span style="color: black;">这般</span>把钥匙彻底断电。</p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从保险盒取电就<span style="color: black;">能够</span>,只要<span style="color: black;">保准</span>电流值(要<span style="color: black;">思虑</span>电台最大功率发射时和同一保险下的其他设备全开的最大值)</p>至于6楼所提的峰值电流大会影响行车安全,我觉得并<span style="color: black;">无</span>必要担心,远光灯闪几下会影响行车安全么? 功率都差不多吧,<span style="color: black;">况且</span>车辆发动状态,有发电机和蓄电池这两个电源<span style="color: black;">同期</span>存在,相对的内阻<span style="color: black;">亦</span>是非常小的,十几安培的电流不会有什么影响。

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">还是<span style="color: black;">剧烈</span><span style="color: black;">意见</span>接电瓶+-极,正极<span style="color: black;">最少</span>要有15A融断保险,负极有些品牌有保险</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> 那是<span style="color: black;">由于</span><span style="color: black;">每一个</span>国家的法律对负极<span style="color: black;">需求</span>尽有<span style="color: black;">区别</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> 出口量大的品牌为了避免<span style="color: black;">区别</span>国家的法律<span style="color: black;">需求</span>,做的线材+-极均有15A融断保险</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> 车台功率<span style="color: black;">通常</span>会到50W风值,<span style="color: black;">尤其</span>是<span style="color: black;">运用</span>V段的时候</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">当你搭进是后窗除雾保险盒后面走线,那当<span style="color: black;">同期</span><span style="color: black;">运用</span>两设备时可能保险会融断,即使不立即融断<span style="color: black;">亦</span>会发热量骤增</p>so....直接接电瓶吧,别听修车的乱说

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">有<span style="color: black;">要求</span>的话当然是电瓶直接取电,受<span style="color: black;">要求</span>限制,走保险后面取电<span style="color: black;">亦</span><span style="color: black;">能够</span>,</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">前提是不要和其他设备共用一个保险丝,保险丝安倍数在20-30A<span style="color: black;">就可</span>,当然前提是<span style="color: black;">亦</span>要看保险丝前面的线束的可承受安倍数;<span style="color: black;">另一</span>,保险的问题,我觉得单接正极保险<span style="color: black;">亦</span><span style="color: black;">无</span>问题。</p>个人意见供参考。

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">车载电台在汽车上连接电源<span style="color: black;">通常</span><span style="color: black;">能够</span>从三个途径获取:<span style="color: black;">蓄电池端口、保险丝盒接线端口、点烟器取电口</span>。 <span style="color: black;">‍</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">车载电台原厂说明书一律都<span style="color: black;">举荐</span>从汽车蓄电池端口取用供电电源。这种获取电源的<span style="color: black;">方法</span>只要连接<span style="color: black;">靠谱</span>,将<span style="color: black;">能够</span><span style="color: black;">得到</span>汽车电力系统的最大能量输出。这种连接电源的<span style="color: black;">办法</span>,安装前要<span style="color: black;">尤其</span><span style="color: black;">重视</span><span style="color: black;">检测</span>汽车的电力系统<span style="color: black;">是不是</span>是12V电压标准。大中型车辆采用24V和48V电压标准的可能<span style="color: black;">很强</span>,还有新上市新能源电动力型号的汽车。汽车电力系统为24V或48V标准时,<span style="color: black;">能够</span>采取降压稳压电源降压后<span style="color: black;">得到</span>13.8V或12V直流电压输出供电台<span style="color: black;">运用</span>,<span style="color: black;">亦</span><span style="color: black;">能够</span>采取在汽车电池组中找到有12V电压输出的中间抽头给电台供电。前者<span style="color: black;">增多</span>降压稳压电源<span style="color: black;">增多</span>了热功耗损失白白浪费电能,并且<span style="color: black;">增多</span>了出故障的可能性;后者只取汽车整组电池的部分<span style="color: black;">运用</span>,<span style="color: black;">倘若</span>电台功率大且<span style="color: black;">运用</span>频繁可能<span style="color: black;">导致</span>汽车电池组放点不平衡而影响<span style="color: black;">运用</span>寿命。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从蓄电池连接电台电源的缺点是:安装时电线布放麻烦;在发动机引擎盖中走线<span style="color: black;">不小心</span>,存在<span style="color: black;">很强</span>的安全隐患;电台供电不受汽车电门<span style="color: black;">掌控</span>,存在忘记断开电台电源<span style="color: black;">导致</span>汽车电池过度放电的危险。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">汽车保险丝盒<span style="color: black;">倘若</span>安装在驾驶室内(<span style="color: black;">通常</span>在仪表板侧面或下面),将电台电源连接到保险丝盒中<span style="color: black;">能够</span>避免从引擎盖穿线到驾驶室的麻烦,<span style="color: black;">亦</span><span style="color: black;">无</span>电源线在发动机舱中布放<span style="color: black;">欠妥</span><span style="color: black;">导致</span>故障的危险。有的车型保险丝盒中预留了车载电器设备<span style="color: black;">运用</span>的接线端子,<span style="color: black;">能够</span>很方便地引出12V电源线。<span style="color: black;">倘若</span>找到受汽车电门<span style="color: black;">掌控</span>的保险丝触电,<span style="color: black;">那样</span>电台的供电电源还<span style="color: black;">能够</span>在拔<span style="color: black;">落车</span>钥匙时自动切断,减少了因忘记关闭电源<span style="color: black;">导致</span>汽车蓄电池过度放电的可能性。汽配市场<span style="color: black;">亦</span><span style="color: black;">能够</span>购买到一种插接在保险丝触点位置的引出线,它<span style="color: black;">能够</span>在原车保险丝安装座上<span style="color: black;">得到</span>12V电源正极输出,电源负极<span style="color: black;">能够</span>在汽车内的任意接地端取得。<span style="color: black;">运用</span>这个<span style="color: black;">办法</span>从保险丝端口取电时要<span style="color: black;">重视</span><span style="color: black;">检测</span>取电处保险的功率容量<span style="color: black;">是不是</span>足够为电台供电。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">保险丝盒取电的缺点是:需要对汽车电路比较<span style="color: black;">熟练</span>;电台发射时,取电保险的端口要承受<span style="color: black;">很强</span>的电流<span style="color: black;">经过</span>,有可能超出原有设计<span style="color: black;">需求</span>,<span style="color: black;">显现</span>别的<span style="color: black;">情况</span>。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">前面两种给电台供电的<span style="color: black;">办法</span>,无论采用哪种,都需要安装者<span style="color: black;">熟练</span>汽车结构,并且有汽车电路改装的<span style="color: black;">基本</span>和经验;在穿线时或多或少都要破坏原车密封件、内饰盖板等。<span style="color: black;">倘若</span>从汽车内的点烟器取电口取电就相对容易多了。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">汽车点烟器取电插口<span style="color: black;">能够</span><span style="color: black;">供给</span>12V<span style="color: black;">最少</span>100W-120W功率的输出。<span style="color: black;">倘若</span>车载电台将发射功率设定在中小功率状态,只要最大工作电流不超过7A-8A,从车内点烟器插口连接<span style="color: black;">得到</span>电源是最简便的途径。只是要找到一个合格的足以承受100W功率的点烟器插头比较困难,<span style="color: black;">通常</span>只能从质量较好的大功率车载电器上拆用。<span style="color: black;">倘若</span>在汽配市场购买点烟器插头用来连接电台电源,要<span style="color: black;">尤其</span><span style="color: black;">重视</span>其触电簧片的质量。买回来后最好自己再调校一下簧片形状,让它有更大的压力和接触面<span style="color: black;">保准</span>与汽车点烟器插口有完全<span style="color: black;">靠谱</span>的连接。<span style="color: black;">运用</span>时<span style="color: black;">亦</span>随时<span style="color: black;">重视</span>观察大电流时<span style="color: black;">是不是</span>有发热现象,并且在<span style="color: black;">运用</span>一段时间后再次<span style="color: black;">检测</span><span style="color: black;">调节</span>簧片<span style="color: black;">情况</span>。</p>
