Technical Field

[0001] The invention belongs to the technical field of transformer substations, and in particular relates to a combined assembled box-type transformer substation and an assembly method thereof. Background Art

[0002] Box-type substation, also called prefabricated substation or prefabricated substation. It is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines transformer step-down, low-voltage distribution and other functions organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation.

[0003] Existing box-type substations are relatively large in size and mostly use welded structures. After the shell is welded, rust removal, grinding, puttying, primer spraying, and topcoat spraying must be carried out outdoors. Not only does it have a long production cycle and cannot meet customer requirements, it is also harmful to the human body and causes air pollution. It is also facing government requirements to suspend production and make rectifications at any time, and production is not guaranteed. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the features and performances of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1 As shown, firstly, a combined assembled box-type substation is proposed, including a box-type substation frame 15 in the shape of a rectangular parallelepiped, a box-type substation top cover in the shape of an inverted V-shape in cross section, a box-type substation second-layer top 14, a box-type substation partition wall 17 and a box-type substation outer door 16;

[0035] Among them, Figure 3 As shown, the box-type transformer partition wall 17 is detachably fixed in the box-type transformer frame 15, and the box-type transformer frame 15 is divided into three functional rooms, namely, a high-voltage room, a low-voltage room and a transformer room; the box-type transformer second-layer roof 14 and the box-type transformer top cover are detachably fixed on the top of the box-type transformer frame 15, and the box-type transformer top cover is located above the box-type transformer second-layer roof 14; the box-type transformer outer door 16 includes a high-voltage room door, a low-voltage room door and a transformer room door, which are arranged outside the high-voltage room, the low-voltage room and the transformer room in turn, and the high-voltage room door, the low-voltage room door and the transformer room door are all hinged to the box-type transformer frame 15, and a mesh door is arranged on the inner side of the transformer room door;

[0036] like Figure 5 As shown, the top cover of the box-type transformer is a spliced ​​structure, a water diversion trough 11 is provided below the joint of the spliced ​​structure, and a reinforcement beam 18 is fixed above the second-floor top 14 of the box-type transformer, and the reinforcement beam 18 is used to support the top cover of the box-type transformer.

[0037] In the above-mentioned box-type substation, the bottom of the box-type transformer frame 15 is provided with a wiring area, a transformer box placement area, an electrical cabinet placement area, etc., which are used to place the corresponding power distribution equipment. At the same time, relevant holes are provided on the box-type transformer partition wall 17 for wiring and installation of equipment switches, etc. The function of the second-layer roof 14 of the box-type transformer is not only to form a closed air duct in the transformer room, which is convenient for exhausting air and heat dissipation, but also to strengthen the overall strength of the box-type transformer. A reinforcement beam 18 and a water diversion trough 11 are provided between the second-layer roof 14 of the box-type transformer and the top cover of the box-type transformer, which are respectively used to enhance the overall structural strength and to guide rainwater, etc. Since the box-type transformer needs to pay attention to the indoor temperature during use, in the case of summer sun exposure, thermal insulation materials can be filled between the top cover of the box-type transformer and the second-layer roof 14 of the box-type transformer.

[0038] In addition, in the above-mentioned combined assembled box-type substation, the box-type substation frame 15 includes a bottom frame 19, a column 20 and an upper door stop 21. The bottom frame 19 and the upper door stop 21 are both rectangles of the same size. The column 20 is detachably fixed at the four corners of the bottom frame 19 and the four sides of the bottom frame 19, and the upper door stop 21 is detachably fixed at the upper end of the column 20. The bottom frame 19 is generally welded with channel steel, and a corresponding bottom plate is installed on the bottom frame 19 for placing corresponding electrical equipment. In addition, a bolt needs to be pre-welded at the place where the bottom frame 19 needs to fix the column 20, and a bolt hole for threaded connection with the bolt needs to be processed on the column 20, and the column 20 and the bottom frame 19 are connected and fixed by bolts.

[0039] The top cover of the box transformer includes a side top cover 12, a top cover plug 13 and a top cover ridge 10. The cross-sectional shape of the top cover ridge 10 is an inverted V shape. The side top cover 12 is rectangular. The long sides of the top cover ridge 10 are respectively connected to the long sides of one side top cover 12. The other long side of the side top cover 12 is fixed to the top of the box transformer frame 15. The upper part of the top cover plug 13 is an inverted V shape. The shape of the top cover plug 13 is adapted to the shape of the gap formed on both sides of the box transformer top cover and the box transformer second-layer top 14. The top cover plug 13 is used to fill the gap between the box transformer top cover and the box transformer second-layer top 14. The inverted V-shaped top cover ridge 10 can effectively prevent the deposition of rainwater. The side top covers 12 on both sides of the top cover ridge 10 can be provided with pouring holes connected to the water diversion trough 11 to further discharge rainwater.

[0040] The side top cover 12 and the top cover ridge 10 are both formed by splicing multiple sections, and the length of each section of the side top cover 12 and the top cover ridge 10 is the same as the length of the top of the functional room corresponding to the side top cover 12 and the top cover ridge 10, and a seam is formed at the splicing of each two sections. The side top cover 12 and the top cover ridge 10 are set as a multi-section splicing structure for the convenience of manufacturing and transportation.

[0041] like Figure 4 As shown, the second-layer roof 14 of the box-type transformer includes the second-layer roof 24 of the high-voltage room, the second-layer roof 22 of the low-voltage room and the second-layer roof of the transformer room, and the second-layer roof of the transformer room is provided with a fan and a light travel switch. The second-layer roof 14 of the box-type transformer can be designed and manufactured accordingly according to the conditions of each functional room, and the transformer room will generate a lot of heat during operation, and a fan can be installed to discharge the heat in time.

[0042] In addition, for the convenience of use, a transformer indicator device, a wind hook and a door lock may be provided on the transformer outer door 16.

[0043] Furthermore, the screws use 8.8-grade M10 screws, and the self-tapping screws use 8.8-grade M6 self-tapping screws.
