Problems solved by technology

The semi-buried box-type substation puts the transformer under the ground, so the volume of the box-type substation on the ground is greatly reduced, but because the transformer is placed under the bottom, the predictability of safety accidents is not strong, and the humid underground environment will cause great damage to the equipment. The moisture in the foundation foundation also has a great impact on the equipment, and it is more likely to cause safety accidents in rainy seasons
[0006] 2. Compact box-type substation, this kind of box-type substation mainly reduces its volume and floor area at the same time, and the reduction of floor space is achieved by its volume reduction, but it is still unavoidable to install the foundation
[0019] It is not difficult to see that in order to maintain better heat dissipation performance, the above-mentioned transformers are forced to dissipate heat by external force, while natural heat dissipation is o...

Embodiment 1

[0104] The invention provides a box-type substation, figure 1 and figure 2 It is the front view and perspective view of the box-type substation, such as figure 1As shown: the box-type substation is equipped with a high-voltage switch room 1, a low-voltage switch room 2, a transformer room 3, a metering room 4 and a cable room 5. The metering room 4 can also be used as a high-voltage and low-voltage connection area, and the cable room 5 includes high-voltage cables. Room 51 and low-voltage cable room 52; it should be noted that the metering room can be one, and the high-supply high meter or high-supply low meter method is used to save corresponding functional equipment and simplify its structure. It can be called a high-voltage metering room or a low-voltage metering room. Metering room; what adopt in the present embodiment is that high-voltage metering (connection) room 41 and low-voltage metering room 42 can be used as metering cooperation, and wherein high-voltage metering...

Embodiment 2

[0109] The only difference between this embodiment and embodiment 1 is that the cable chamber 5, Figure 3-6 is a schematic diagram of the box-type substation, such as image 3 As shown, there is a two-layer structure between the high-voltage cable room 51 and the low-voltage cable room 52. Along the X direction, the upper layer is the high-voltage switch room 1, the metering room 4 and the low-voltage switch room 2, and the lower layer is the transformer room 3; the high-voltage cable room 51 and the low-voltage cable chamber 52 are the same height as the two-layer structure respectively. The improvement of the structure of the cable room 5 can realize that the incoming cables of the box-type substation can be fed in both up and down, and can be expanded to be applicable to situations such as overhead lines that need to be fed in from the top of the box-type substation. Such as Figure 4 As shown, at this time, the incoming cable enters the line from the bottom of the box-t...

Embodiment 3

[0111] The difference between this embodiment and Embodiment 1 is that the bottom surfaces of the high-voltage and low-voltage switch rooms of the box-type substation in this embodiment are not attached to the top surface of the transformer room, and the side walls of the high-voltage and low-voltage switch rooms are respectively connected to the two sides of the transformer room. side walls, such as Figure 4 As shown, as a preferred embodiment, the side wall of the high-voltage switch room 1 in the box-type substation is in close contact with the side wall of the transformer room 3. Similarly, the side wall of the low-voltage switch room 2 is in contact with the side wall of the transformer room 3. The side walls are attached to each other. In addition, the bottom surface of the high-voltage and low-voltage switch rooms is not flush with the top or bottom surface of the transformer room but parallel; The character-shaped structure in the box-type substation is similar, but s...

Abstract

The invention discloses a box-type substation. The box-type substation at least comprises a high-voltage switchgear chamber, a low-voltage switchgear chamber and a transformer chamber, which are distributed in the shape of steps, wherein equipment circuits in the high-voltage switchgear chamber, the low-voltage switchgear chamber and the transformer chamber are M-shaped, U-shaped or V-shaped. The box-type substation is different from the prior art on the aspect that a structure that a plurality of layers are distributed up and down is creatively adopted, so that the size of the box-type substation is 1 to 3 times smaller than that of the traditional substation, the occupation area is reduced, the box-type substation is convenient to transport, and the transportation cost is reduced; a downward foundation of the traditional box-type substation is not required to be manufactured, the difficulty for constructing a project is reduced, the cost is reduced, and adverse influence to each piece of equipment in the box-type substation by humidity in the semi-buried foundation can be better avoided.

Description

technical field [0001] The invention relates to a substation, in particular to a box-type substation, which belongs to the technical field of electrical equipment. Background technique [0002] The box-type substation is a substation that organically combines functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution, and is installed in a fully enclosed, movable steel structure box. Box-type substation has a series of advantages such as strong complete set, short power transmission cycle, strong environmental adaptability, convenient installation, safe and reliable operation, less investment and quick effect, so box-type substation has been widely used in urban network construction and transformation public power distribution. With the acceleration of the modernization process of municipal construction, the box-type substation will gradually replace the original civil power distribution room and become a new type of complete p...
