我有一台 APC Smart-UPS 3000。
上周日，它自动关机了。事发时办公室里没有人，也没有人登录。
这可能是什么原因造成的？我担心这种情况可能会再次发生。
日志显示输出“已收到关闭命令”，但没有说明由谁或在哪里执行。本地面板？计划测试？远程？有哪些可能性？

如果有人知道的话，我将不胜感激。谢谢
编辑：2019 年 10 月 21 日，附加信息：几天前，UPS 离线，由于“逆变器故障”无法启动。因此，这种意外关机可能是 UPS 内部出现故障的征兆，我敦促遇到此类故障的任何人小心使用设备。我希望 APC 在发生这种情况时提供更详细的诊断。

有趣的是，与我的一样，当电池容量为 70% 时，Smart-UPS SRT 3000（+3 个附加电池组）无缘无故地切换了插座组 1 和 2。

另一个例子是当 UPS 出现故障并进入故障旁路（旁路可用时）。大多数 Smart-UPS 在线设计（例如 SURT 和 SURTA 型号）在故障旁路时会关闭 UPS 的电池充电器。因此，电池会随着时间的推移而放电。当电池电量不足时，UPS 会关闭 UPS 的负载，因为它无法永远保持故障旁路（需要最低电池电压才能保持在线 Smart-UPS 的逻辑电源开启）。
答案2
有软件监控 UPS 吗？是否发生过停电？
看起来您的 UPS 有三相电源。如果任何一相断电，我预计它会开始断电循环。UPS 在通知系统关闭后通常会关闭电源。这是在关闭请求后使系统恢复正常运行所必需的。
我使用 NUT（网络 UPS 工具）软件来管理 UPS 和系统。其文档解释了关机/重启周期。大多数其他软件的行为相同。
答案3
您的电池可能有问题，并且当 UPS 尝试进行定期自我检测时，它无法维持电池的电力。
您应该访问其界面并执行有意的电池测试以查看它是否成功。
