  一样伟大来说,电路可分为单线和双线圈体系,但修筑呆板的延伸臂挖掘机紧张是单线体系单线体系电路的运用进程中也会出现一些错误,影响变乱的顺利举行,以下加长臂挖掘机出租我为你先容电路拦阻的拦阻诊断要领。
  Generally speaking, the circuit can be divided into single line system and double coil system. However, in the process of using the single line system circuit of the extension arm excavator of construction machinery, there will be some errors, which will affect the smooth progress of the work. The following extension arm excavator rental I will introduce the fault diagnosis method of the electrical circuit fault for you.
  打破:
  Break:
  断路器的拦阻是当熔断器或自动掩护开关完备时,电路开关接通,电气配置不变乱。
  The fault of the circuit breaker is that when the fuse or automatic protection switch is in good condition, the circuit switch is on and the electrical equipment does not work.
  构成这种拦阻的缘故缘故原因有三:,电路中的插头是松动的,寥落或有油,第二,开关打仗氧化或失效,第三是断了或拿铁丝拿铁不壮实。
  There are three reasons for this kind of fault: first, the plug in the circuit is loose, falling off or oil; second, the switch contacts oxidation or failure; third, the wire is broken or the latte is not firm.
  短路:
  Short circuit:
  拦阻标明,当电路主开关或某一电路开关接通时,保险丝烧断,自动掩护开关方法,导线发热烧断。这种拦阻通常是由于电气元件的绝缘子粉碎,招致电源线与车身打仗。短路检测要拥有两种:一种是欧姆计检测要领,另一种是实行灯孕育发生熔丝检测要领。
  The fault shows that when the main switch of the circuit or a circuit switch is connected, the fuse is burnt out, the automatic protection switch acts, and the wire is burnt out. This kind of fault is usually caused by the insulator damage of electrical components, which causes the power line to contact with the body. There are two short circuit detection methods: one is ohmmeter detection method, the other is test lamp fuse detection method.
  欧姆表查抄要领:堵截电路主开关,拆下拦阻电路的保险丝,将欧姆表1米笔铁,另1米笔衔接在拆下的螺纹头上。要是欧姆计丈量的电阻值很小,则丈量点前面的电路很短,不然拦阻点在丈量点反面。要是欧姆计丈量的电阻值正常,则重新衔接接线头,然后逐段取出螺纹举行查抄。
  Inspection method of ohmmeter: cut off the main switch of the circuit, remove the fuse of the faulty circuit, connect the 1 meter pen iron of the ohmmeter and the other 1 meter pen on the removed thread head. If the ohmmeter measures a small resistance, the circuit in front of the measuring point is short, otherwise the fault point is behind the measuring point. If the resistance measured by the ohmmeter is normal, reconnect the connector and take out the thread one by one for inspection.

  实行灯熔丝查抄要领:先拆下电气装置开关,然后将实行灯两端与熔丝块两端详连,接通主电路。实行灯亮时,熔断器与电气装置开关之间发生短路;要是测试灯不变乱,且测试灯在电气装置的开关接通后才亮,则电气装置与开关之间发生短路。
  Test lamp fuse inspection method: first remove the switch of the electrical device, then connect the two ends of the test lamp and the two ends of the fuse block, and connect the main circuit. When the test lamp is on, there is a short circuit between the fuse and the switch of the electrical device; if the test lamp does not work and the test lamp is on only after the switch of the electrical device is on, there is a short circuit between the electrical device and the switch.
  为了确定短路点的细致位置,应逐段撤除缝线。要是测试灯在装置后不亮,则表现短路点在装置后;另一种要领是在江苏快三开奖结果翻开点之前。为了便于影象,查抄要领可以概括为:衔接测试灯,而不是off保险;翻开主开关,逐段撤除缝线;后车灯没亮,这局部有点标题。
  In order to determine the specific location of the short circuit point, the suture shall be removed one by one. If the test lamp does not light up after removal, it means that the short circuit point is after removal; another method is before we turn on the point. For the convenience of memory, the inspection method can be summarized as: connect the test lamp instead of the off fuse; turn on the main switch and remove the suture section by section; the rear lamp is not on, which is a bit problematic.
  要是一个保险丝或自动掩护开关控制多个并联支路,应先拆下全部开关讨论,然后将各支路讨论逐延续接到端子柱上。当触碰支路时,测试灯的灼烁度较低(测试灯与电气配置串联以减小电流),说明该支路无短路;要是测试灯十分亮,则分支有短路。
  If a fuse or automatic protection switch controls multiple parallel branches, remove all switch connectors first, and then connect each branch connector to the terminal post one by one. When touching the branch, the light intensity of the test lamp is low (the test lamp is connected in series with the electrical equipment to reduce the current), indicating that there is no short circuit in the branch; if the test lamp is very bright, there is a short circuit in the branch.
