1. mg28指针钳形表互感器怎么拆下来
用钳形电流表分别测量一次电流I1和二次电流I2,电流比K=I1÷I2。互感器一次额定电流In1=In2×K,当二次额度电流In2为5A时,In1=5×K。电流互感器变比为In1/5。

测电流:将空调设置于制冷或制热高速风状态下运转,在低压截止阀工艺口处,边加氟边观察钳形电流表变化。
当接近空调铭牌标定的额定工作电流值时,关闭氟瓶阀门。
4、测压力法:将空调置于制冷高速风状态(冬天,制热需要加氟时,将空调设置于强制制冷状态或将室温传感器置于27℃左右的温水中。
模拟夏天温度让空调处于制冷状态)下运转,在低压截止阀工艺口。
边加氟边观察真空压力表的低压压力,当低压在0.49mpa(夏天)或0.25mpa(冬天),关闭氟瓶阀门。
使用空调的话是必须要进行加氟的,这样空调才能够正常的去进行工作。
3. mg28指针钳形表用法
钳形电流表最大的优点是可以在不断电的情况下测量电流。钳形电流表主要分为指针式和数字式两大类。钳形电流表按结果和用途的不同可分为专门测交流的式钳形电流表和交直流两用的电磁系钳形电流表。
通常在测量电流时需要将被测电路断开,才能将电流表或的一次绕组接到被测电路中。而使用钳形电流表,则无需断开被测电路就可以测量被测电流。钳形电流表虽然准确度等级不高,通常为2.5级或5.0级,但因其使用方便,故而得到了广泛的应用。钳形电流表一般用于测量电压不超过500v的负载电流。常用的钳形电流表按其结构形式不同,分为互感器式和电磁式两种。其中有只测交流电流的t301型钳形电流表、既测交流电流又测交流电压的t302型钳形电流表及mg系列的交直流两用钳形电流表等。因其使用方便所以广泛使用
4. mg27钳形表故障维修
1、在使用钳形电流表前应仔细阅读说明书,弄清是交流还是交直流两用钳形表。
2、被测电路电压不能超过钳形表上所标明的数值,否则容易造成接地事故,或者引起触电危险。
3、钳形表每次只能测量一相导线的电流,被测导线应置于钳形窗口中央,不可以将多相导线都夹入窗口测量。
4、钳形表测量前应先估计被测电流的大小,再决定用哪一量程。若无法估计,可先用最大量程档然后适当换小些,以准确读数。不能使用小电流档去测量大电流。以防损坏钳型表。
5、钳型表钳口在测量时闭合要紧密,闭合后如有杂音,可打开钳口重全一次,若杂音仍不能消除时,应检查磁路上各接合面是否光洁,有尘污时要擦拭干净。
6、由于钳形电流表本身精度较低,在测量小电流时,可采用下述方法:先将被测电路的导线绕几圈,再放进钳形表的钳口内进行测量。此时钳形表所指示的电流值并非被测量的实际值,实际电流应当为钳形表的读数除以导线缠绕的圈数。
7、维修时不要带电操作,以防触电
5. mg26钳形表怎么用
《摩托车驾照考试指南》依据2013年1月1日开始实施的《机动车驾驶证申领和使用规定》(公安部第123号令)编写,系统地介绍了摩托车驾驶人考驾照所涉及的基本知识和实际操作技能。
考试基本信息
考试介绍
驾驶证全称为机动车驾驶证,又作“驾照”,依照法律机动车辆驾驶人员所需申领的证照。有摩托车驾照才能合法骑摩托车。除了可以直接报考初学二轮摩托车、初学三轮摩托车外,还可申请增驾二轮摩托车、增驾三轮摩托车。无论是初学或增驾车型的,学习过程和费用是一样的。
摩托车驾驶证主要分以下三种类型
1、D驾照可以驾驶所有摩托车车型、三轮摩托。准驾车辆:发动机排量大于50ml或者最大设计车速大于50km/h。
2、E驾照∶可以驾驶电动轻便摩托车、电动二轮摩托车。准驾车辆:发动机排量大于50ml或者最大设计车速大于50km/h的三轮摩托车。
3、F驾照只能驾驶电动轻便摩托车。准驾车辆:发动机排量小于等于50ml,最大设计车速小于等于50km/h的摩托车。
另外,电动自行车属于非机动车,不需要驾驶证;但驾驶电动自行车,应当年满16周岁以上;电动轻便摩托车和电动摩托车均属于机动车,和普通摩托车相比,只是燃料种类不同(电动摩托车燃料种类为电,普通摩托车燃料种类为油),所以均需要考取相应的驾驶证方可上路行驶。
报考条件
考取摩托车驾照和汽车驾照一样,去当地交警队、车管所报名,等待考试。
1、初学摩托车驾照要求
1、年龄在18~60周岁,身份证原件;
2、六张近三个月内白底一寸彩照;
3、外地人员需要准备居住证;
4、体检表及体检收据,双眼矫正视力必须是5.0以上,体检项目主要是检测是否色盲、残疾、视力不佳等。
2、有其他驾照需要增驾
1、年龄在18~60周岁,身份证原件;
2、六张近三个月内白底一寸彩照;
3、外地人员需要准备居住证;
4、体检表及体检收据,双眼矫正视力必须是5.0以上,体检项目主要是检测是否色盲、残疾、视力不佳等;
5、驾驶本原件,驾驶本满一年且一年内没有12分记录。
报考时间
一般情况下考摩托驾照报名考试时间可以自己到交警大队或者车管所去预约,正常办公时间均可,周一至周五(法定节假日除外)。 摩托驾照一般一个月左右的时间,就能拿到摩托车驾驶证。
考试时间
根据自己预约的时间,自行去约定的考场进行考试即可。
考试内容
科目一、四考试:理论考试
根据所在地不同,有的地方直接发一本书,回去看就行了,有的则需要刷卡上课,50道题,每题2分,考试时间45分钟,90分合格。考试内容:
1、道路交通安个法律、法规和规章。
2、交通信号及其含义。
3、安全行车、文明驾驶知识。
4、高速公路、山区道路、桥梁、隧道、恶劣气象和复杂道路条件下的安全驾驶。
5、转向失控、制动失灵等紧急情况时的临危处置。
6、机动车构造、安全装置的日常检查和维护。
7、事故后自救、急救以及常见危险物品知识。
科目二考试:绕桩、坡道、单标桥
绕桩是在一条直线上,有三个杆子,要求以S型绕过三个杆子,然后再绕回来,过程中脚不能落地,车子不能熄火,车子不能压黄线。平时自己练一下,在考试时速度稍微慢一些,稳一些,不要紧张。还有的有土路、上坡、直角弯路、单边桥、蛇形路、起伏路等,考的可能都不太一样,一般都是绕一圈就过了。上坡的时候按道理是要在上面停一下的,不过一般没人管,上去的时候速度放慢点就行了。
科目三:路考
路考很简单,按考官的要求路线走就行了,分为起步、过人行横道、过公交车站、掉头、靠边停车。
需要注意的是:增驾也是三科目都要再考一遍。
考试日程安排
摩托车驾照科目一考试通过3工作日内发“驾驶技能准考证明”,有效期2年。《机动车驾驶证申领和使用规定》第26条第一款规定:摩托车科目二要在“证明”下发10日后约考。
考试费用
1、驾驶证制作工本费:10元/证
2、科目一理论考试费用:42元/人/次
3、科目二场地考试费用:105元/人/次
4、科目三道路考试费用:139元/人/次
那么,考取“D证、E证、F证”的费用总计为10+42+105+139=296元,当然,这个地方也略有差异,但基本上相差不大,比如之前山东德州公布的考试费用为350元左右,当然,这个考试费用,是指驾驶人直接在车管所报名,不经过驾校学习、考试的费用。
证书领取
考试合格后,车管所整理完档案核发驾驶证,增驾的收回原驾驶证,换领新驾驶证。
备考策略
科目一、四学习工具
科目一和科目四都是上机考试,可以下载驾校一点通软件,选择摩托车考试,就会有相应的题库出来。考试内容可以分为两大类:
1、常识题
这种问题比较简单,只要三观正常,按照正常人的思维去走,不要看错题目,就可以答对。
2、理论题
理论题这个是自己的三观和常识覆盖不了的了,得靠做笔记、死记硬背,比如撤销驾照几年内不得重考、驾车逃逸而致死判几年之类的。
总之,上机考试需要细心、仔细的审题,可以在APP上多练习几次,每次在90分以上,就可以上考场了。常错题可以做笔记整理,加强记忆,比如:
科目二实战练习
其实驾照最难的其实是场地考试。在报名成功后,就可以按照驾校的通知,进行练车,熟悉场地。
场地如下:
摩托车科二的考试项目为绕桩、坡道定点停车和起步、通过单边桥。
两轮摩托车
1、绕桩
1、进入第一根桩的之前,尽量贴着边线行驶,只要不压线就行,车轮驶过桩杆就可以打方向,但方向不能打死要留一定的间隙,否则摩托很容易就会停下。
2、驶进第一根桩和第二根桩后,观察第二根桩平行出去的边线位置,车头对准那个点即可回正方向并朝那个方向行驶。
3、贴近边线后开始微调方向,观察车把手位置当把手和桩杆平行即可打方向倾斜过去,后面的桩也以此类推。
2、坡道定点停车和起步
1、起步前踩下刹车,防止汽车后溜;
2、如果摩托车是熄火状态的,则先捏紧离合退回空挡,启动后再准备起步;
3、摩托车启动后捏紧离合,向前踩一下换挡杆挂入1挡,然后慢慢拧油门给油;
4、稳住油门,观察转速表,挡转速表指针保持4000转左右,慢慢松开离合,直至车身明显抖动;
5、车身抖动也就是半联动状态,此时稳住离合不要动,然后快速松开脚刹并加油起步上坡,车辆平稳起步后在慢慢松完离合。
3、单边桥
对于单边桥来说,基本是没有什么技巧的,注意以下几点即可:
1、车速不宜太慢,太慢车身容易左右晃,从而导致重心不稳;
2、目光放远看,不要盯着轮胎接触位置,有了宏观视野驾驶才会平稳,如果光盯着车轮看,一旦有偏差,手就会不自觉地左右晃动把手去调整,从而影响结果;
3、上桥后手臂要放松,把手不要握太紧,过度紧张的话,在调整方向时容易用力过猛。
三轮摩托车
考试内容主要是桩考、坡道定点停车和起步、通过单边桥。
1、桩考
在桩考开始后,我们要把握进桩的速度和角度,不然会导致没有足够的转向空间,会导致压线。所以我们应该从边线和标杆的中间位置一档进入,保持半联动状态,需要油门和离合的正确配合,在考试过程中,一定慢而稳,但也不能太慢。
2、坡道定点停车和起步
坡上起步有四种方法,分别是:手刹法、半联动发、直接起步法、一脚两用法。其中直接起步法比较简单,只需要直接松开刹车,马上踩油门,拉开手刹即可,这种方法只需要多架联系,在考场上就会很简单。
3、通过单边桥
在通过单边桥时,需挂二档,在上桥前保持好心态,身体也要平稳,找好上桥角度,切记不要踩着离合不放,早点松离合,给油。使车平稳地骑上单边桥。合理的控制好车速。
科目三实战练习
摩托车科目三的考试内容由省级公安机关交通管理部门确定,一般会连同科目二合并考。科目三考试内容:起步、直线行驶、变更车道、通过路口、靠边停车、掉头等项目。
详细流程
①上车前、逆时针绕车一周检查车辆,起步前开左转向灯并向左后方转头观察后方情况,确认安全后起步。
②起步后慢松离合,直接并入左侧车道,车正后关闭转向灯,加油提速。
③通过人行横道时降速,左右摆头观察情况,前轮到人行横道上进行刹车降速。
④通过人行横道后加油、加档。
⑤掉头前减速减档,减档后打左转向灯,左右摆头观察情况,掉头后车正关闭转向灯。
⑥公交车站前收油左右摆头观察情况,刹车减速,过公交车站时加油加档提速。
⑦通过人行横道时降速,左右摆头观察情况,通过后减档,降低车速。
⑧靠边停车前打右转向灯往右看,确保安全后停车,车停好后关闭右转向灯,考试结束。
⑨把车开到起点处下车。

6. mg28指针钳形表电路图
钳形电流表最大的优点是可以在不断电的情况下测量电流。钳形电流表主要分为指针式和数字式两大类。钳形电流表按结果和用途的不同可分为专门测交流的式钳形电流表和交直流两用的电磁系钳形电流表。
通常在测量电流时需要将被测电路断开,才能将电流表或的一次绕组接到被测电路中。而使用钳形电流表,则无需断开被测电路就可以测量被测电流。钳形电流表虽然准确度等级不高,通常为2.5级或5.0级,但因其使用方便,故而得到了广泛的应用。钳形电流表一般用于测量电压不超过500v的负载电流。常用的钳形电流表按其结构形式不同,分为互感器式和电磁式两种。其中有只测交流电流的t301型钳形电流表、既测交流电流又测交流电压的t302型钳形电流表及mg系列的交直流两用钳形电流表等。因其使用方便所以广泛使用
7. mg28指针钳形表电路板内图片
钳形电流表分为可测交流电流,如T301,T302,MG24和可测交直流电流如MG20,MG21,二类,有的还可测量电压如T302,MG24。所以用钳形表测电器好坏不好用,只能用万用表检查。
钳形电流表只能测电动机故障来判断水泵是否有负载。水泵电动机上有铭牌,钳表测的电流和标注近似说明水泵在工作,如电流很小是空载电流的话,水泵没有起压力,在空转。电流很大不出水或许有机械故障。例如盘根压得太紧
钳形表是不能直接测量开关好的。钳形表是测量供电线路电流的。如果一定要用钳形表来判断开关的好坏,那只能将开关合上,把供电线路上的负载都开启,然后用钳形表测量线路上是否有电流,有电流可以初步确定开关是好的。判断开关好坏应用万用表来测量。
8. mg28钳形表故障维修
钳形万用表不开机修复方法如下:
方法一:
首先梳理一下线路,找到复位上拉电阻及对地电容,用万用表量复位端电压不足一伏,可以确定复位问题导致的不开机。
方法二:
拆下电阻量100K正常,又拆下电容量,0.1uf,正常无漏电,找了个47k电阻代换100k电阻焊回后开机正常了,量一下复位电压2.68v,装机。
