1. mine electric locomotives battery capacity is reduced. In addition to battery aging, over-discharge, active material reduction, plate detachment, quality problems, etc., the electrolyte density is too low, which is also the cause of the battery capacity reduction. In daily maintenance, the specific gravity of the electrolyte is often measured by a hydrometer. When the specific gravity is lower than 1.28, adjust the standard value with the multi-standard solution to ensure that the battery is charged with enough power to ensure the capacity of the battery.
2. mine electric locomotives battery surface sparks. During the charging process of the battery, a spark is generated on the surface of the battery, generally at the corners, and between the plastic separator or the steel plate, which is a discharge phenomenon. The reason is that the electrolyte overflows, such as the battery cell, the battery cover is broken, the electrolyte is dripping during the injection, the liquid injection in the battery is too full, the cock is short or not tight when the locomotive is running, and the primary battery is formed between the two points. , a potential difference is generated, and an electric spark is generated through the discharge circuit. Rinse the electrolyte with clean water and keep the battery surface clean and dry. Maintain a reasonable liquid level, 2025mm above the top of the partition; tighten the special exhaust plug before the locomotive is running. If the battery case is broken, it must be disposed of or replaced.
3. mine electric locomotives battery damage. If the battery is damaged, it is mostly caused by short circuit of the positive and negative plates of the battery itself. If a regular number of batteries or even the entire power supply box is damaged, it is caused by external causes, such as excessive external load, long-term overload traction, or even short circuit. When the insulation of the positive or negative lead cable is damaged, it is short-circuited with the unequal potential pole. Some battery short-circuit and other factors will cause damage to the battery, and must be fully taken care of. When the locomotive is running, avoid overload traction. Check the insulation of the electrode lead cable carefully, add insulation tube; prevent large current discharge of the battery, and avoid current flow. Large damaged battery.
