Detailed ways

Below in conjunction with accompanying drawing and embodiment the structure of the present utility model is described in detail:

As shown in Fig. 1, Fig. 2, Fig. 3, metering box described in the utility model comprises cabinet, mounting plate 1, dividing plate 2, carry out protection switch 13, carry out knife switch 15, outlet control switch 18, collector 7. Door 3, upper door 10, lower door 11, observation window 4, upper door observation window 5, and zero line row 19 are installed on the box body. Several outgoing line control switches 18 are housed inside the box body. The box body of the chassis is divided into the left space and the right side space through the installation plate 1, the left space is an independent unit room, and the space on the right side of the box body is arranged into upper and lower two independent unit rooms through the partition plate 2, each independent The unit room has a door, and the left side independent unit room is provided with a door 3, and the lower part of the door of the left side independent unit room is provided with an observation window 4; There are 8 upper door observation windows 5 on the door, and the left independent unit room is the incoming line protection switch and the three-phase four-wire input unit room 6, as shown in the upper right side of Figure 2, and the lower right independent unit room is equipped with The lower door 11, the independent unit room on the lower right side is the power distribution output and control unit room 8; as shown on the left side of Figure 2, the independent unit room on the upper right side is the power data copying and remote data transmission unit room 9.
