Several Knowledge Points About How UPS Power Supply Can Easily Cause Fires
Nov 14, 2023
The common causes of fires in UPS power supplies are as follows:
1. The virtual connection of the cable joint causes excessive contact resistance. After the temperature rises, the contact surface is seriously oxidized, which causes the contact resistance to continue to increase. Eventually, it will cause electrical sparks or even arcing, igniting nearby combustibles and causing a fire.
2. A short-circuit accident occurs in the back-end lines, switches or loads of the UPS power supply, causing fire inside the UPS or explosion of high-power components.
3. There is serious metal dust in the UPS power supply installation place. The dust is sucked into the UPS machine through the UPS cooling fan. When the concentration reaches a certain value, it will cause a fire inside the UPS.
4. Changes in the UPS power supply working environment such as temperature, humidity and other factors can cause battery failure and cause fires.
5. Problems such as deformation of the battery casing, leakage of electrolyte, insufficient capacity, uneven battery terminal voltage, etc. may lead to fires.
The above problems cannot be underestimated and are often ignored by the majority of users. They must be treated correctly and nip in the bud. The losses caused by unofficial fires will be huge.
