Haixing reveals the reasons for the thermal runaway of the motor unit for you

The thermal runaway from the generator set may be a sign of problems inside the equipment. How should we judge the cause of the thermal runaway from the generator set and then confirm the faulty parts? To facilitate everyone's review, Haixing has compiled common reasons for thermal runaway from generator sets, as follows:

1. Exothermic reaction of oxygen composite reaction. The oxygen composite reaction of the oxygen produced by the positive electrode at the negative electrode is an exothermic reaction. If the heat emitted by the reaction cannot be released, the temperature of the battery will increase.

2. The battery structure is not conducive to heat dissipation. The structural features of valve-controlled sealed lead-acid batteries are sealed, lean electrolyte, and tightly assembled with fine glass fiber diaphragms, which are not conducive to heat dissipation. That is, this battery is not like a liquid-rich battery, which can dissipate heat in the battery through exhaust gas, a large amount of electrolyte and a non-close arrangement between the plates.

3. The ambient temperature is high. The higher the ambient temperature, the worse it is to dissipate heat from the battery, and the increase in temperature will increase the floating charging current of the battery, and the floating charging current and temperature will increase each other. Therefore, charging equipment should have a temperature compensation function. That is, the floating charging voltage is lowered when the temperature rises.

4. The floating charging voltage is too high. If the floating charge voltage is set too high, the floating charge current will increase, causing the battery temperature to rise.

The above are just a few common reasons for thermal runaway from generator sets compiled by Haixing. If you find that there are other reasons for thermal runaway from generator sets during operation, you might as well inform Haixing. Haixing's staff will sort it out to facilitate sharing with more people in need.
