Mine Electric Locomotives is very similar to the battery car in one respect and has a special charger, and it is usually used to charge the Mine Electric Locomotives with a charger, but what happens to the charger will cause the mine to work on the Mine Electric Locomotives The normal use of a certain impact. So what should we do with the charger for Mine Electric Locomotives? How to repair it?
1, the output voltage is normal, but the charging current is very small In this case, you should check whether the device is bad or damaged, if everything is normal, then replace the charger to troubleshoot.
2, a serious fever, there are shell burning deformation This is mainly part of the user often carry the parts caused by loose parts caused by the failure. Mainly as follows: the voltage is not working properly, a lot of heat, serious when the charger shell deformation, circuit board charred, resulting in voltage damage. Weld soldering can be re-welded. If you still can not rule out the fault, you need to check whether there are components open circuit.
3, the power indicator light when charging, charging indicator orange First of all, please check the charger output plug and the battery box charging plug is not tightened. If there is no problem, check the battery compartment
The above fuse is open or the fuse holder has loose contact bad phenomenon.
In addition, some models to open the battery lock before charging. If the above failures are excluded, consider the charger output line is open, you can use the multimeter voltage file (200V file) to measure the charger's no-load voltage, should be 41-44V (with 36V battery due to different charger) , If not, may be the charger output line open, and the charger to open, for an output line, you can rule out the fault.
Note: When replacing the output line of the charger, be sure to pay attention to the positive and negative of the original machine should not be reversed.
4, the power indicator light does not shine, charging indicator does not shine, charging indicator light does not check the charger input power plug is connected, you can plug the plug into the normal power outlet, if the situation remains the same, the charge Shell open, observe the machine fuse connection is intact, with or without open circuit, if there is no circuit, check the power input line is good, in the exclusion of power input line failure, check the circuit board near the high pressure area components Weld phenomenon. In addition, the open circuit will lead the initial failure, such as the machine fuse has been broken, then do not replace the Ampere fuse (charger fuse tube is generally 2A), should focus on checking its components for damage, if damaged, The same type of replacement can be used.
5, heat in, and accompanied by abnormal sound, charge failure does not enter the cause of the output voltage is due to damage caused by vibration. In addition, the components of the open or Weld can also cause the failure.
6, the output part of the copper foil blown
Open the charger after the charger output part of the copper foil burned, which is usually the battery positive and negative reverse the result, the resulting failure will lead to many components of the charger damage. If the charger fuse is not bad, then usually replace the components will be broken after the copper foil
On the back to normal. If the charger fuse has been broken, the fault is more serious, there may be sound, the power indicator light and the charging indicator light and flash the cause of the malfunction is damaged components can be replaced damaged components, and make the charger output voltage in normal work Within range.
The above is the Mine Electric Locomotives charger conventional troubleshooting and maintenance, after encountering such problems can be resolved in a timely manner.
