DETAILED DESCRIPTION

[0020] 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;

[0021] Please see Figures 1 to 4 In this utility model, the power quality management device includes a housing 1. Equivalently spaced partitions 2 are fixedly installed inside the housing 1, dividing the interior of the housing 1 into vertically arranged mounting slots 3. Parallel guide plates 4 are installed inside the mounting slots 3, and a positioning mechanism 5 is installed on the guide plates 4. Harmonic modules 6, sequence component modules 7, and voltage phase and current modules 8 are sequentially inserted into the interior of the mounting slots 3 from top to bottom. A control manager 9 is fixedly installed on the partition 2 located at the top inside the housing 1, controlling the operation of the harmonic modules 6, sequence component modules 7, and voltage phase and current modules 8.

[0022] In this invention, the housing 1 serves as the device casing. During use, the control manager 9 connects to the power grid to sample and analyze the fluctuation types generated by the current power grid. Then, based on the data analysis structure, it controls the corresponding harmonic module 6, sequence component modules 7, and voltage phase and current module 8 to operate independently, enabling independent processing of different types of power quality problems. Furthermore, during peak periods, multiple problems can be processed simultaneously, resulting in higher efficiency and stability. Simultaneously, the harmonic module 6, sequence component modules 7, and voltage phase and current module 8 are all independently modularly installed, making fault handling and maintenance more efficient and flexible. This allows the device to achieve independent parallel processing of multiple problems, high efficiency and stability, and improved equipment operation stability and processing efficiency. It solves the problem in existing technologies where multiple problems are still processed by a single processing unit, resulting in lower efficiency, especially during high-load periods when the power grid is under heavy load. Because the processing unit is single, different types of power grid fluctuation problems need to be processed sequentially, leading to processing delays and decreased stability.

[0023] Please see Figure 3 The control manager 9 includes a control module 91 and a sampling module 92. The control module 91 is installed inside the control manager 9 and is electrically connected to the sampling module 92. The sampling module 92 is connected to the power grid.

[0024] In this invention, the sampling module 92 is connected to the power grid and collects power grid data in real time. The data is then transmitted to the control module 91 for analysis. Based on the analysis results, the control module 91 controls the harmonic module 6, the sequence component modules 7, and the voltage phase and current module 8 to operate independently, thereby achieving real-time and efficient power quality management.

[0025] Please see Figure 2The positioning mechanism 5 includes a fixed block 51 and a positioning screw 52. The outer side of the fixed block 51 is fixedly connected to the inside of the guide clamp 4. One end of the positioning screw 52 passes through and is threaded to the other side of the fixed block 51, and is pressed and positioned by the harmonic module 6, the sequence component modules 7 and the voltage phase and current module 8 respectively.

[0026] In this invention, the harmonic module 6, the sequence component modules 7, and the voltage phase and current module 8 are installed and positioned by rotating the positioning screw 52 and moving it horizontally along the fixing block 51, making them easier to install and remove.

[0027] Please see Figure 1 and Figure 4 The mounting slot 3 at the bottom is equipped with a redundant module 31, which is a comprehensive processing module.

[0028] In this invention, the redundant module 31 serves as a comprehensive processing module. When one type of power grid fluctuation problem is particularly prominent, the control module 91 activates the redundant module 31 as a supplementary mechanism to assist in the processing. Furthermore, the redundant module 31 can achieve comprehensive processing of multiple problems and can adjust and assist different processing modules to perform auxiliary operation, thereby further ensuring the stability of equipment operation.

[0029] Please see Figure 1 Among them, a cooling fan 10 is fixedly installed on the top of the box 1.

[0030] In this invention, the cooling fan 10 is used to cool the components inside the housing 1, thereby improving the stability of the equipment operation.

[0031] Please see Figure 1 The front of the housing 1 is equipped with an opening and closing door 11, and a mechanical lock 12 is installed on the opening and closing door 11.

[0032] In this utility model, the opening and closing operation of the box 1 is realized by the cooperation of the opening and closing door 11 and the mechanical lock 12, which facilitates the later maintenance operation.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
