[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a factory-fabricated, compact indoor or outdoor distribution system that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution within a fully enclosed, portable steel structure that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, and heat-insulated. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after civil substations. Photovoltaic box-type substations are commonly located in regions with low rainfall and hot climates. Existing box-type substations typically have a single door, meaning that opening the first door allows direct access to the equipment room and electrical components. This approach compromises electrical safety and provides inadequate protection within the box. A double-door structure can improve electrical safety. However, existing box-type substations with double-door structures often experience uncontrolled door opening, making them susceptible to strong winds when used outdoors. Maintenance personnel are easily affected by wind blowing through the box door after opening it. Therefore, it is necessary to improve the existing photovoltaic box-type substations in view of the characteristics of the use environment of photovoltaic box-type substations.

[0013] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0014] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0016] like Figure 1-2 As shown, the double-door structure of a photovoltaic box-type substation includes a box body, a front box panel 1 provided on the front of the box body, a rear box panel 2 provided on the back of the box body, and a top cover 3 provided on the upper end of the box body. Several outer box doors 4 are mounted on the front box panel 1, one side of the outer box door 4 is hinged to the front box panel 1. A front partition 5 is provided inside the box body, and an equipment section is formed between the front partition 5 and the rear box panel 2. The equipment section is divided into several equipment rooms 7 by partition panels 6. An operating room 8 is formed between the front partition 5 and the front box panel 1. Several inner box doors 9 are mounted on the front partition 5, one side of the inner box door 9 is hinged to the front partition 5, and the width of the operating room 8 is greater than that of the inner box door 9. Before entering the box-type substation, the outer box door 4 is first opened outward, and then the inner box door 9 is opened after entering the operating room 8. The design of the double-door structure improves the safety of the box-type substation and enhances the safety protection during the operation of the box-type substation.

[0017] Furthermore, the two adjacent inner doors 9 form a double-door structure, and the two inner doors 9 in the double-door structure are connected by a door lock. The two adjacent outer doors 4 form a double-door structure, and the two outer doors 4 in the double-door structure are connected by a door lock.

[0018] Furthermore, the front panel 1 is fixedly connected to a plurality of outer stoppers 10 for restricting inward movement of the outer door 4, and the front bulkhead 5 is fixedly connected to a plurality of inner stoppers 11 for restricting inward movement of the inner door 9. When the outer door 4 is closed, the outer stoppers 10 block the outer door 4, preventing it from further inward rotation. When the inner door 9 is closed, the inner stoppers 11 block the inner door 9, preventing it from further inward rotation.

[0019] Furthermore, the top cover 3 is provided with a plurality of outer limiting posts 12, which correspond one to one with the outer door 4. When the outer door 4 is opened 90 degrees, it is stopped by the corresponding outer limiting post 12. When the outer door 4 is opened, it is stopped by the outer limiting post 12 after it is fully opened, thereby restricting its further rotation.

[0020] Furthermore, a magnet 13 is mounted on the outer limiting column 12, and a magnetic attraction portion 14 is provided on the outer door 4 for the magnet 13 to attract. The magnet 13 can attract the outer door 4 and thus fix the outer door 4 in the open state.

[0021] Further, such as Figure 3 As shown, the outer limiting column 12 is provided with a movable hole 15, in which a spring 16 and a movable push rod 19 are sequentially provided. One end of the movable push rod 19 is fixedly connected to the spring 16, and the other end extends out of the movable hole 15 and is fixedly connected to the magnet 13. A limiting ring 17 is fixed at the opening of the movable hole 15. The end of the movable push rod located in the movable hole 15 is fixedly connected to a retaining ring 18, and the spring 16 is fixedly connected to the outer limiting column 12. After the outer box door 4 is opened, the magnet 13 attracts the outer box door 4 and fixes it, preventing the wind from blowing the outer box door 4 and causing it to shake at will or close suddenly.

[0022] It is worth mentioning that the technical features such as magnets and springs involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of this utility model patent.
