[0002] A prefabricated substation, also known as a box-type substation, is a compact power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment into a prefabricated, fully enclosed steel structure box according to a specific wiring scheme. Its core function is to convert high-voltage electrical energy into low-voltage electrical energy suitable for end users and to realize power distribution and protection. It is widely used in urban power grids, industrial parks, new energy power plants, and rural power construction to undertake regional power distribution tasks.

[0003] As an important component of the power distribution system, the stability of the internal electrical equipment of the prefabricated substation directly affects the reliability of power supply. Traditional maintenance methods for prefabricated substations rely on manual inspection of each item. The maintenance requires a large number of equipment, such as independent infrared thermal imagers, multimeters, insulation resistance testers, etc., which leads to the tools being scattered and inconvenient to transport. Furthermore, auxiliary transport tools such as handcarts cannot pass through the narrow space of the environment in which the prefabricated substation is located, resulting in low inspection and maintenance efficiency and failing to meet the needs of efficient maintenance in complex environments.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example, refer to Figure 1 - Figure 6A maintenance equipment for a prefabricated substation includes a first enclosure 1, which is hinged to a second enclosure 2. The first enclosure 1 and the second enclosure 2 are connected by a hinge. In the closed state, the first enclosure 1 is used to integrate and load maintenance tools for easy handling. In use, it can be flipped open to remove tools from the inside for maintenance work. An adjustment support assembly 6 is installed on the bottom wall inside the first enclosure 1. A control terminal 7 and an infrared camera 8 are installed at the end of the adjustment support assembly 6. The adjustment support assembly 6 is used to adjust the orientation of the infrared camera 8 so that it is aimed at the electrical equipment in the prefabricated substation to detect infrared heat sources and check whether there are abnormal heat sources above the heat radiation range of the electrical equipment. This allows the equipment to determine whether there are faults such as short circuits or loose connections in the internal wiring of the prefabricated substation. The control terminal 7 is electrically connected to the infrared camera 8 and is used to control and adjust the operating parameters of the infrared camera 8.

[0029] The second box 2 has support seats 21 at both the left and right ends, and there is an accommodating space 22 between the two support seats 21 for storing commonly used maintenance tools.

[0030] Connecting components 4 are installed on the support bases 21 at both ends. The second enclosure 2 is connected to a detection terminal 5 through the connecting components 4. This terminal is used to detect parameters such as voltage, current and resistance between electrical equipment, thereby determining the cause of the fault and facilitating the maintenance of the box-type substation.

[0031] Furthermore, the first box 1 is provided with a connecting pin 11 on the side away from the hinge, and the second box 2 is provided with a lock body 23 on the side away from the hinge. The connecting pin 11 and the lock body 23 are locked together. By correspondingly connecting the connecting pin 11 and the lock body 23, the first box 1 and the second box 2 are connected and closed, so as to prevent the first box 1 and the second box 2 from being opened by collision during transportation.

[0032] The second box 2 is also equipped with a handle 3 on the side away from the hinge for easy handling.

[0033] Furthermore, the adjustment support assembly 6 includes a base 61 fixedly connected to the bottom wall of the first housing 1. A rotating platform 62 is rotatably connected to the top surface of the base 61. The rotating platform 62 can rotate around the central axis of the base 61. A hinge block 63 is hinged to the top of the rotating platform 62. The hinge block 63 can rotate around its connection end with the rotating platform 62 in the front-back direction of the first housing 1, thereby driving the pitch linkage 64 to move, thus changing its relative angle with the bottom surface of the first housing 1. The other end of the hinge block 63 is hinged to the pitch linkage 64. The pitch linkage 64 can rotate around its connection end with the hinge block 63 in the left-right direction of the first housing 1, thereby adjusting the height of the second fixed plate 65. The top of the pitch linkage 64 is hinged to the second fixed plate 65. The infrared camera 8 and the control terminal 7 are mounted on the second fixed plate 65. The second fixed plate 65 can rotate relative to the pitch linkage 64, thereby driving the infrared camera 8 to move, thereby controlling and adjusting the shooting area of ​​the infrared camera 8.

[0034] In use, by rotating the hinge block 63, the front and rear end faces of the hinge block 63 are made parallel to the bottom surface of the first housing 1. Then, the pitch linkage 64 is rotated so that the front and rear end faces of the pitch linkage 64 are parallel to the side wall of the first housing 1. The second fixing plate 65 is rotated so that the second fixing plate 65 rotates around the pitch linkage 64 and rotates to a position where the upper and lower end faces of the second fixing plate 65 are parallel to the front and rear end faces of the pitch linkage 64. This allows the adjusting support assembly 6 to be folded and easily stored in the first housing 1.

[0035] Furthermore, the control terminal 7 is hinged to the second fixed plate 65 for adjusting its pitch angle, making it easier for the user to observe the image captured by the infrared camera 8. The control terminal 7 includes an imaging display screen 71 and adjustment buttons 72 for adjusting the operating parameters of the infrared camera 8.

[0036] Furthermore, the testing terminal 5 includes a first fixing plate 51, with handles 52 symmetrically provided at both ends of the first fixing plate 51. The handles 52 are engaged with the connecting components 4 at both ends to fix the testing terminal 5 above the support base 21. This prevents the testing terminal 5 from shaking in the first housing 1 and the second housing 2 and colliding with other maintenance tools in the housing, thus avoiding damage. At the same time, when the testing terminal 5 is connected to the support base 21 through the connecting components 4, it is directly above the accommodating space 22, thereby preventing the tools stored in the accommodating space 22 from moving around during transportation.

[0037] Furthermore, the testing terminal 5 also includes a testing instrument 53 fixedly installed in the middle of the first fixed plate 51 and several terminals 54 electrically connected to the testing instrument 53. The terminals 54 are fixedly installed on the first fixed plate 51. By using wires to connect electrical equipment to the corresponding terminals 54, the voltage, current, resistance and other parameters of the electrical equipment are tested, thereby determining the cause of the fault and performing maintenance and replacement operations.

[0038] Furthermore, each of the two connecting components 4 includes two sets of spring pieces 41 arranged opposite each other along the left and right direction of the second housing 2. The tops of the two sets of spring pieces 41 are symmetrically connected with wedges 43. The two sets of wedges 43 are close to each other. There is a snap-fit ​​groove 42 between the two sets of spring pieces 41 and the top wall of the support base 21 and the bottom wall of the wedges 43. The handle 52 is snapped into the snap-fit ​​groove 42. By setting two opposing spring pieces 41, during installation, by installing the first fixing plate 51 downwards, the handle 52 contacts the two spring pieces 41 of the corresponding connecting component 4. The handle 52 applies an outward force to the spring pieces 41 by contacting the wedges 43, forcing the spring pieces 41 to bend and deform. This allows the handle 52 to enter the snap-fit ​​groove 42 between the wedges 43 at the tops of the two sets of spring pieces 41. The spring pieces 41 are reset under the action of elasticity, preventing the handle 52 from falling out, thereby fixing the detection terminal 5 to the support base 21.

[0039] Furthermore, anti-slip pads 9 are fixedly connected to the four corners of the bottom wall of the first box 1 and the second box 2. The anti-slip pads 9 are used to contact the ground when the first box 1 and the second box 2 are unfolded, increasing the friction between the first box 1 and the second box 2 and the ground, and preventing the first box 1 and the second box 2 from sliding on their own.

[0040] Working principle: During use, by adjusting the angle of the support component 6, the infrared camera 8 is aimed at the part of the box-type substation to be inspected. The infrared camera 8 outputs the infrared image of the captured area through the display screen 71, which makes it easy for the user to check whether there is an overheated area. The detection terminal 5 is used to detect the electrical equipment in the overheated area to check whether its voltage, resistance or current and other parameters are within normal values. Based on the detection results, the electrical equipment is repaired or replaced. When moving and maintaining the equipment, the support component 6 is rotated to a folded state for easy storage in the first box 1. The detection terminal 5 is fixed on the support base 21 of the second box 2 through the connecting component 4. The first box 1 and the second box 2 are closed and locked together by the connecting pin 11 and the lock body 23, which facilitates the overall moving and maintenance of the equipment.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
