Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to a single-slot branch detection module housing unit. Background Art

[0002] Power distribution is the connection between the power system and the user, responsible for distributing electric energy. Traditional distribution networks use DTU or FTU to measure, control and protect the high-voltage lines of distribution transformers. These technologies can control switches or circuit breakers to open and close in the event of short circuits and other faults, achieving fault isolation and self-healing of power supply in non-faulty areas. However, this technology has a wide impact when a fault occurs, and sometimes even has an adverse impact on the power consumption of all users in the entire area.

[0003] To improve this problem, a branch detection module is set up in the prior art to monitor and protect each branch of the low-voltage distribution line individually; when a local line fails, the module can quickly locate and isolate the faulty branch, and quickly restore power supply to the non-faulty branches to avoid power outages in the entire substation.

[0004] In recent years, with the diversification of power types and the access to new energy sources such as wind power generation, solar power generation, and hydrogen power generation, higher requirements have been put forward for the working status monitoring of low-voltage distribution network lines. Under this condition, the corresponding branch detection module is required to be equipped with more structural components to ensure its performance requirements. As a common branch detection module, the single-slot branch detection module can be set according to the number of line branches in the corresponding substation, which has better flexibility than the integral branch detection module; the assembly style of the single-slot branch detection module is similar to that of the air switch, usually a left-right assembly structure, which makes the size of the single-slot branch detection module usually smaller and the overall width narrower, which makes the traditional upper and lower assembly shell unit structure have certain assembly limitations when assembling the single-slot branch detection module:

[0005] On the one hand, the traditional upper and lower assembly shell unit structure is relatively simple, and deep groove installation is used when assembling structural components, resulting in poor assembly performance; and the increase in functional units will also increase certain difficulties in assembling structural components in its internal structure cavity;

[0006] On the other hand, the combination of highly integrated internal components may cause the branch detection module in the side-mounted assembly state to have defects in heat dissipation and anti-interference performance during use after assembly, affecting the normal use of the branch detection module.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0026] See also Figure 1~Figure 3A preferred embodiment of a single-slot branch detection module housing unit. In this embodiment, the single-slot branch detection module housing unit is used as an accessory to prepare a single-slot branch detection module. Its corresponding single-slot branch detection module is the same as other single-slot branch detection modules of the same type. Multiple single-slot branch detection modules can be combined according to actual conditions to obtain a corresponding circuit branch detection system.

[0027] The housing unit of this embodiment includes a separable first shell and a second shell, wherein the first shell has a first side plate 10 and a top plate 9, a bottom plate, a front plate 8 and a rear plate formed on the first side plate 10. The first shell is surrounded by the first side plate 10, the top plate 9, the bottom plate, the front plate 8 and the rear plate to form a volume cavity with a side opening; and the main body of the second shell is the second side plate 12, which is arranged opposite to the first side plate 10 and can be closed and assembled on the opening side of the corresponding volume cavity on the first shell. The first side plate 10, the top plate 9, the bottom plate, the front plate 8 and the rear plate of the first shell are integrally formed injection-molded structural parts; and the second shell is also integrally formed by injection molding.

[0028] In order to improve the assembly performance of the second shell on the open side of the first shell, the first shell is formed with two front and rear insertion holes on the outer edge of the bottom plate, three threaded assembly columns are formed on the outer edge surface of the first side plate 10, and two buckle grooves are arranged on the outer edge of the lower surface of the top plate 9; correspondingly, the second shell is formed with two positioning buckles 15 on the inner side of the second side plate 12 corresponding to the insertion hole positions, three matching threaded hole seats 11 are formed at the corresponding threaded assembly column positions, and two buckles 14 matching the buckle grooves are arranged at the corresponding buckle groove positions on the upper outer edge; when the second shell is covered and assembled on the open side of the first shell, the positioning buckle 15 is first inserted into the insertion hole position of the first shell, and then the buckle 14 is used for pre-fixation and buckling. After buckling and fixing, the fastening bolts are used to tighten the threaded overlapping position of the threaded hole seat 11 / threaded assembly column to complete the combined assembly of the two.

[0029] The first side panel 10 and the second side panel 12 are both provided with a window hole 13, and the outer edge of the window hole 13 has a stepped surface. The outer shell unit is formed with a heat dissipation aluminum plate 6 through the window hole 13 with the stepped surface. The heat dissipation aluminum plate 6 matches the inner surface of the first side panel 10 on the side of the cavity corresponding to the volume cavity and keeps the surface flush, and a number of parallel ribs 7 are formed on the outer surface of the heat dissipation aluminum plate 6; the number and orientation of the ribs 7 can be set according to actual conditions in different embodiments. In the present embodiment, three ribs 7 are arranged transversely. In addition, in the present embodiment, the ribs 7 arranged on the surface of the heat dissipation aluminum plate 6 on the first side panel 10 are staggered with the ribs 7 arranged on the surface of the heat dissipation aluminum plate 6 on the second side panel 10, and matching staggered overlap portions are provided on the outer edges of the ribs 7 of the two, and the staggered overlap portions are step surface overlap portions; this allows two single-slot branch detection modules of the same model to be assembled sideways in the following manner. Figure 3 The ribs 7 on the outer side of the heat dissipation aluminum plate 6 are offset against each other in the manner shown, so as to reserve a hot runner space 17 in the offset assembly space between the ribs 7 .

[0030] The housing unit uses the volume cavity on the first shell as the component assembly cavity, and the components used to realize the corresponding functions of the branch detection module are assembled in the component assembly cavity. When assembling components in the component assembly cavity, it is necessary to bypass the threaded assembly column preset on the inner outer edge surface of the first side plate 10. As a functional structure, the surface of the top plate 9 of the first shell is formed with a light guide column assembly position 3 and a label structure position 2. The light guide column assembly position 3 can realize the reading of component information data in the component assembly cavity by assembling the light guide column, and the label structure position 2 can distinguish the detection branches of different single-slot branch detection modules by attaching labels.

[0031] The first side plate 10 of the first shell and the second side plate 12 of the second shell are also respectively formed with a front base assembly structure 4 and a rear base assembly structure 5 on both sides of the front and rear ends of the lower part of the corresponding shell units; the correspondingly formed single-slot branch detection module can be combined and assembled with the front base assembly structure 4, the rear base assembly structure 5 and the matching assembly structure to obtain the aforementioned circuit branch detection system.

[0032] To facilitate assembly, a combination of assembly structures for assisting in the assembly of detection module components is formed on the inner surface of the first side panel 10. The combination of these assembly structures is a combination of brackets, partitions, slots, buckles, limit buckles, and assembly columns. The assembly structure is directly arranged on the outer edge of the window hole 13 or is connected to the outer edge of the window hole 13 through a base connecting seat. Considering that the detection module components may need to be installed against the first side panel 10 side of the component assembly cavity, a layer of copper alloy VC heat spreader 16 can also be mounted on the inner surface of the corresponding first side panel 10 as a component abutment surface. The copper alloy VC heat spreader 16 is directly mounted on the inner surface area of ​​the heat dissipation aluminum plate 6. The second side panel 12, as an outer covering structure, does not require the copper alloy VC heat spreader 16 for inner surface mounting, and only a smooth surface structure can be used.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the scope of protection of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the scope of protection defined by the claims attached to this application.
