  如何找出伸缩臂挖掘机的电路故障
  How to find out the circuit fault of telescopic arm excavator
  电路可分为单线、双线系统,探索这样一个大型机械的伸缩臂是采用单线系统,在单线系统中会发生故障,影响正常工作停止。接下来,我们将研究挖掘出伸缩臂电路问题的故障排除方法。
  Circuits can be divided into single-line and double-line systems. To explore such a large mechanical telescopic arm is a single-line system. Faults will occur in the single-line system, which will affect the normal operation of the stop. Next, we will study the troubleshooting methods of digging out the telescopic boom circuit problems.
  断路器:
  Circuit breaker:
  熔断器故障或自动断路维护情况,有交流电机,接通电路开关,电气设备不能正常工作。
  In the case of fuse failure or automatic circuit breaking maintenance, there are alternating current motors, switch on circuit switches, and electrical equipment can not work properly.
  造成这一缺陷的原因有三:一是插头松动,在电路中丢失或被污染,二是开关触点氧化失效或三线或空气线应用铁不真实。
  There are three reasons for this defect: first, the plug is loose, lost or polluted in the circuit; second, the switch contact oxidation failure or the unreal application of iron on the third or air lines.
  短路电流:
  Short circuit current:
  未能关闭电路开关或电路开关、保险丝、自动维护开关、电线加热和熄灭。故障通常是由于电气局部绝缘体损坏,形成电源线与本体接触。检查短路有两种方法:一种是ommi测试,另一种是检查保险丝的方法。
  Failed to turn off circuit switch or circuit switch, fuse, automatic maintenance switch, wire heating and extinguishing. Faults are usually caused by the damage of local electrical insulators, resulting in the contact between the power cord and the body. There are two ways to check short circuit: one is OMMI test, the other is fuse test.
  欧姆表方法:切断电路开关,取出故障电路保险丝,欧姆表取1表铁和1表断丝。若母表中的一种小型指示电路,用于测量电阻,或跟踪故障点的检测点。正确测量电阻值在若母表中,跟踪回退和回退检查截面a。
  Ohmmeter method: cut off circuit switch, take out fault circuit fuse, ohmmeter take 1 meter iron and 1 meter broken wire. If there is a small indicator circuit in the master meter, it can be used to measure the resistance or to track the detection point of the fault point. If the resistance value is measured correctly in the master table, follow back and check section a.
  测试熔丝方法:先将电器开关设为off,然后尝试两端的熔丝座;2 .在码头上,点灯,然后关掉电路开关。如果先导灯、短路保险丝和设备开关不亮,并连接到电气开关指示灯上,则表示电气设备与交流之间短路。
  Test the fuse method: first set the electrical switch off, then try the fuse holder at both ends; 2. On the wharf, light the lamp, and then turn off the circuit switch. If the pilot lamp, short-circuit fuse and device switch are not on and connected to the indicator lamp of the electrical switch, the short-circuit between the electrical equipment and AC is indicated.
  以便准确地确定在哪里缝短点的部分。如果飞行员没有打开背面,在打开后指出短点,反之亦然,然后再翻转。为便于记忆,该方法可概括为:连接测试灯,而不是断掉的保险丝由交流连接,逐段连接;拆下缝线和前灯。这是错误的。
  In order to accurately determine where to sew the short part. If the pilot does not open the back, point out the shortcomings after opening, and vice versa, and then flip. To facilitate memory, the method can be summarized as: connecting the test lamp, instead of the broken fuse, which is connected by alternating current, and connecting step by step; removing the stitches and headlights. This is wrong.

  如果保险丝的数量为1或并联支路的数量为自动维修开关控制时,应将所有的开关线全部拆下,然后每条支路连接线将逐一与码头发生碰撞。如果你触摸和拿一张纸,请尽量把灯调暗(测试灯和电气设备中的串联,电流减小),支短路故障如果测试灯是好的,说明有短路。
  If the number of fuses is 1 or the number of parallel branches is controlled by automatic maintenance switch, all switch lines should be removed, and then each branch connection line will collide with the wharf one by one. If you touch and take a piece of paper, try to dim the lamp (test lamp and electrical equipment in series, current decreases), branch short circuit fault if the test lamp is good, indicating a short circuit.
  接触不良:
  Poor contact:
  与PC400挖掘机伸缩臂接触不良,红色灯泡,电机弱,电流回路大,有时甚至引起头部或烧蚀。这个问题一般是由于插头连接不正确造成的焊接不良和导线接触氧化不良。有两种检查方法:一种是ommi测试,另一种是light测试。
  Poor contact with telescopic arm of PC400 excavator, red light bulb, weak motor, large current circuit, sometimes even cause head or ablation. This problem is generally due to improper plug connection resulting in poor welding and poor wire contact oxidation. There are two ways of checking: one is OMMI test, the other is light test.
  欧姆表测试:断开主开关,检查电路开关,用欧姆表测量接触电阻。
  Ohmmeter test: disconnect the main switch, check the circuit switch, and measure the contact resistance with the ohmmeter.
  测试灯测试:检查电路保险丝断开连接或断开自动维护开关,测试灯连接到保险丝或2个端子,自动维护断开电路开关和电源控制开关的安装,同时用一根线接触来检查,可使光线增加,然后连接不良。
  Test lamp test: check circuit fuse disconnection or disconnection of automatic maintenance switch, test lamp connected to fuse or two terminals, automatic maintenance of disconnection circuit switch and power control switch installation, while using a line contact to check, can increase light, and then poor connection.
