Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, and in particular to a modular prefabricated substation. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor or outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after traditional civil engineering substations.

[0003] In existing technologies, prefabricated substations typically employ an integrated design with a fixed and limited internal volume. While this design is relatively simple for initial installation, when new power equipment needs to be added, insufficient internal space forces users to purchase new prefabricated substations for capacity expansion. This not only increases the user's investment costs but also involves a series of complex procedures such as relocation, installation, and commissioning, leading to resource waste and time delays.

[0030] Please see Figure 1-7 This utility model provides a modular prefabricated substation, comprising:

[0031] Main box 1, there are two main boxes 1;

[0032] Expansion box 2 is located between the two main boxes 1;

[0033] Connector 3 is disposed between expansion box 2 and main box 1, and is used to connect expansion box 2 and main box 1 together;

[0034] Two connecting slots 4 are provided on the front and rear sides of the side wall of the main body 1 near the expansion box 2, and two connecting slots 4 are provided on the front and rear sides of the side walls of the expansion box 2. The connecting slots 4 have a receiving cavity 41.

[0035] The limiting mechanism 5 is located inside the receiving cavity 41 and is used to limit the connection 3.

[0036] With the above structure, the entire prefabricated substation is divided into a main box 1 and an expansion box 2, realizing a modular design. The main box 1 and the expansion box 2, as well as the expansion box 2 and the adjacent expansion box 2, are connected by connectors 3, and the connectors 3 are limited by a limiting mechanism 5 to complete the assembly. By adding expansion boxes 2, the overall volume can be expanded, which greatly improves flexibility and expandability.

[0037] The limiting mechanism 5 includes a limiting block 51, a pull rod 52 and a spring 53. The limiting block 51 is slidably provided in the receiving cavity 41. The pull rod 52 is fixedly connected to the side wall of the limiting block 51 away from the connecting groove 4. The other end of the pull rod 52 extends out of the receiving cavity 41. The spring 53 is provided between the limiting block 51 and the side wall of the receiving cavity 41 away from the connecting groove 4.

[0038] By setting the above structure, the connector 3 inserted between the main body 1 and the expansion box 2, as well as between the expansion boxes 2, can be limited so that the connector 3 will not come out of the connecting groove 4.

[0039] Among them, a fixing plate 6 is fixedly connected to the outer walls of the front and rear sides of the main box 1 and the expansion box 2, and above the pull rod 52. A check rod 61 is slidably inserted into the fixing plate 6.

[0040] By setting the above structure, the pull rod 52 can be limited during the assembly process, avoiding the inconvenience of assembly caused by the spring 53 pushing the limit block 51 to reset after the pull rod 52 is released.

[0041] The connector 3 has two limiting slots 31 for the insertion of the limiting block 51.

[0042] The pull rod 52 has a through hole 521 through which the check rod 61 can pass. After the check rod 61 passes through the through hole 521, the pull rod 52 cannot move.

[0043] The main box 1 and the expansion box 2 are sealed together by a sealing strip.

[0044] It should be noted that this utility model is a modular box-type substation. During assembly, pulling the pull rod 52 on the main box 1 causes the limiting block 51 to retract into the receiving cavity 41. During the movement of the pull rod 52, when the through hole 521 aligns with the check rod 61, the check rod 61 will pass through the through hole 521 and lock the pull rod 52. In this way, pulling the remaining pull rods 52 until all the limiting blocks 51 are retracted into the receiving cavity 41, and then pulling out all the pull rods 52 on the expansion box 2, at which point the limiting blocks 51 are all retracted into their corresponding receiving cavities 41, without obstructing the connecting parts 3, and the four connecting parts are removed. 3. Insert it into the four connecting slots 4 on the main housing 1, and then align the expansion box 2 with the connector 3 so that the connector 3 is also inserted into the connecting slots 4 on the expansion box 2. After the alignment is completed, pull the check rod 61 upward. After the check rod 61 disengages from the through hole 521, the spring 53 will push the limit block 51 to move, so that the limit block 51 is inserted into the limit slot 31 on the connector 3, fixing the connector 3 in the connecting slot 4. The assembly is then complete. In the same way, the other main housing 1 can be aligned with the expansion box 2. When it is necessary to expand the volume, the overall volume can be expanded by increasing the number of expansion boxes 2, which is more flexible.
