Abstract

An embodiment of the invention discloses a terminal protection device, comprising a fixing frame, a protection door and a locking structure; One end of the fixing frame is fixedly installed on the power distribution panel, and the other end of the fixing frame is rotatably connected with the protection door; When the terminal is charged, the locking structure between the fixture and the protectiondoor forms a locking structure, and the protection door is in a closed state and is blocked on the surface of the terminal. The technical proposal of the present application solves the technical problem that when expanding the capacity of a communication DC power supply system in which two sets of high-frequency switching power supplies share a set of DC distribution panels, the terminal on the operation side is prone to be loosened by mistake, and the communication of the entire substation is completely interrupted. A DC power distribution panel is also disclosed in that embodiment of the present application.

Description

Technical field [0001] This application relates to the field of power safety technology, and in particular to a terminal protection device and a DC power distribution panel. Background technique [0002] Electric power dispatching agencies, 220kV and above power plants, substations and communication relay stations must all install a communication DC power supply system. The communication DC power supply system usually adopts a dual configuration, that is, two independent high-frequency switching power supplies are configured. Under normal circumstances, a high-frequency switching power supply will be equipped with a set of DC power distribution panels. However, in the case of limited room space, It may happen that two sets of high frequency switching power supplies share a set of DC power distribution panel, such as figure 1 As shown, figure 1 It is a front view of the existing dual power supply DC power distribution panel, the connecting terminal 101 of the first power supply an...
