Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. the

See accompanying drawings 1 to 4, wherein Fig. 1 is a front view of a comprehensive distribution automation DTU, Fig. 2 is a left view, Fig. 3 is a rear view, and Fig. 4 is a front view of the DTU. The distribution automation comprehensive DTU of this embodiment comprises:

Four chambers arranged up and down, the first chamber 11 is a communication chamber, located at the top of the DTU box, used to install communication supporting components, the second chamber 12 is a terminal chamber, located at the lower part of the first chamber , used to install the core module of the power distribution terminal, the third chamber 13 is the battery room, located at the lower part of the second chamber, used to place the battery, the fourth chamber 14 is the cable chamber, located at the bottom of the DTU box, Used to control cable routing, the first chamber 11 and the second chamber 12, the second chamber 12 and the third chamber 13 are respectively arranged on the bottom plate of the second chamber 12 and the third chamber 13 The threading holes of the second chamber 12 and the third chamber 13 are fixed with terminal blocks on the front panels for connecting 8-way or 16-way power distribution automation cables. the

The function realization of each chamber of the present embodiment:

Communication chamber: used to centrally place communication supporting components, such as ONU, optical fiber distribution frame, etc., to realize that the components in the distribution automation communication system and the station terminal DTU are placed in the same box, and the communication module with the DTU is realized through the network cable Connection. the
