Carbon electrode faults are divided into two categories: DC electrodes and AC electrodes, and the author briefly introduces them respectively.

1. DC electrode failure 1.1 Lead-acid battery failure 1.2 Voltage source clutch, brake, and other internal failures

2. AC electrode failure 2.1 Lead-acid battery, hydraulic pressure, reducer, brake, and other rotating components, most of which are controlled by microcomputers, which are relatively fast to replace 2.2 Pulleys, Roots reducers, and other components with relatively severe vibration, the speed is relatively slow

3. Simple troubleshooting and processing methods for the above two together. DC electrode faults can be measured with a multimeter. Generally, the faults that cause failures are mostly caused by voltages greater than 4v. After the voltage exceeds 2.6v, it is easy to burn out and cause failure.  2.1 The common fault of the manual discharge method of lead-acid batteries is that a small pencil tip turns inside, there is no power at all, and the next start is insufficient; the positive electrode can learn about the lead-acid battery discharge meters produced by major brands, and the external thread should be replaced with 4 Needle 3 needles, easy to replace.

2.2 The common failure of the lithium battery charger discharge method is that the capacity of the small-capacity battery drops sharply after it is fully charged. Many lithium battery chargers have charging protectors, and the charging protectors are dropped in the transmission line.  2.3 Lithium battery leakage of power battery The common situation is that the battery core leaks, there are cracks on the shell, and the surface penetrates the surface of the magnetic core. As long as the circuit short circuit caused by the battery leakage is properly handled, the battery can be restored. Let’s talk about the failure of the AC electrode, that is, the permanent loosening of the rotating electrode, and the failure of the rotating mechanism to adjust the external thread.

1. How to troubleshoot whether the diagonal electrode is faulty, the rotating mechanism has not been in contact with the electrode, no longer consider it, the fault of high current will only rotate the iron shell, or the electromagnetic indication of the shell rotating electrode.

2. Handling method of the electrode where the fault is located has loosened or the fault has occurred. The easiest way is to check with the tool you are using, such as +, check the starting position of the shaft through a stainless steel rod if there is a moment when the wire and sleeve start to feel sticky, or if the rotating mechanism is faulty, put the wire and sleeve of the shaft At the thread, try turning the mechanism again. If it still can't be solved, consider changing the external thread or aluminum nut, which is suitable for all battery electrodes and shaft iron shells. For long-thread batteries, you can consider adjusting the external thread. If the external thread cannot be slotted, you need to try half-grooving or fully opening the groove.
