Description

Technical Field

[0001] The present application relates to the technical field of direct current panels, and in particular to a direct current panel with a network timer and sound and light alarms. Background Art

[0002] The DC panel is a DC system with digital control, protection and management. It is mainly used in power plants, substations and other users of DC equipment (such as petrochemical, mining, railways, etc.) in the power system. It is suitable for switch opening and closing and instruments, meters, relay protection and fault lighting in secondary circuits.

[0003] The DC panel time usually used only relies on the timer of the device itself. When the timer has time deviation, it cannot accurately record the time of the fault event, which is not conducive to fault troubleshooting. At present, the DC panel equipment does not have sound and light alarm. When the equipment fails, the on-site staff cannot know it immediately. For this reason, we proposed a DC panel with network synchronization and sound and light alarm functions. Once the equipment fails, it can accurately record the fault time and send out sound and light alarm signals, so that the staff can respond immediately and accurately record the fault time, which is convenient for fault troubleshooting.

[0032] The DC panel with network timer and sound and light alarm proposed in this embodiment has a simple setting method, which is convenient for practitioners in this field to accurately record the fault time. Compared with directly using a timer to record the faults occurring in the DC panel, the DC panel with network timer and sound and light alarm of this application can record the time of the fault event more accurately. The network timer is compared with the timer in the DC panel regularly. When the timer has a time deviation, it is calibrated in time to accurately record the time of the fault event. Specifically, the network timer is compared with the timer in the DC panel group regularly. If they are the same, they are directly output to obtain the completion of the official document; if they are different, they are modified or deleted, and the timer in the DC panel group is entered again for comparison. The above steps are repeated according to the actual situation until the output data results are consistent, and then the output of the official document is completed. On the other hand, a corresponding sound and light alarm is provided inside the DC panel group, and the sound and light alarm is electrically connected to the DC panel. When a fault occurs in the DC group, the dry contact signal is closed, a loop is formed between the sound and light alarm and the DC panel, and a signal is sent out to notify the on-site personnel at the first time. The on-site personnel then obtain the accurate fault time based on the network timer, troubleshoot the fault in the DC panel, improve the efficiency of troubleshooting the fault at the DC panel, and improve the maintenance personnel's ability to repair the fault at the DC panel.
