Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in FIG. 1 , it is a schematic structural diagram of the cabin-mounted screen with panels removed, including a frame 1, and the frame 1 is composed of several horizontal bars 1a and longitudinal bars 1b assembled by fasteners. The inside of the frame 1 is provided with electrical devices, including several previously shown secondary equipment components 2 arranged above the inside of the frame 1 and several horizontal terminal strips 5 arranged below the inside of the frame 1 . The secondary equipment components 2 can be configured in different specifications and combinations according to the layout of the secondary equipment screens of each substation. The secondary equipment assembly 2 is arranged eccentrically to the right side of the frame 1. In order to keep the center of gravity balanced, the left side of the secondary equipment assembly 2 and inside the frame 1 are provided with a longitudinal wiring groove 3.

The dodge door 7 is set opposite to the rear baffle, and is movably connected with the frame 1 through the door shaft. The door shaft is set on the right side of the frame 1, which can realize the 180° rotation of the dodge door 7, and provide enough for substation commissioning, construction and later operation and maintenance personnel operating space. Dodge door 7 preferred single-opening glass doors, flutter door form, single-point lock. Conventional operation and maintenance electric devices such as reset button, toggle switch and pressing plate can be installed on the dodge door 7, and wiring can be carried out after opening.

As shown in Figure 2, it is a schematic diagram of the upper part of the cabin-mounted screen. Each secondary equipment component 2 is correspondingly provided with a row line slot 4 for front wiring, and the optical fiber is routed separately from the conventional wire or network cable. A power supply box 8 is also arranged above the secondary equipment assembly 2 .

As shown in Figure 3, it is a schematic diagram of the lower part of the cabin-mounted panel. The upper terminal of the horizontal terminal block 5 is connected to the wire in the panel, and the lower terminal of the horizontal terminal block 5 is connected to the external cable. An optical fiber storage box 6 for storing redundant pigtails is arranged above the horizontal terminal row 5 . There is a blocking space at the bottom of the cabin-mounted screen that is not less than 100mm away from electrical devices and related wiring.

The cabin-mounted screen of the utility model is sealed with a whole board. Therefore, the board includes a rear baffle and side panels arranged on both sides of the rear baffle, and the rear baffle can be installed close to the inner wall of the prefabricated cabin during installation.
