Description

Technical Field

[0001] This utility model relates to the field of low-voltage power quality management technology, and in particular to an embedded power quality management cabinet. Background Technology

[0002] With the development of power electronics technology, nonlinear loads in power systems have increased significantly, leading to power quality problems in distribution systems such as voltage fluctuations and flashovers, frequency fluctuations, low power factor, harmonics, and three-phase imbalance. To address these issues, appropriate power quality management products are needed to improve the power grid's operating environment. Commonly used power quality management products include intelligent capacitor modules for reactive power compensation, active power filters (APF), and static var generators (SVG). These products are mostly modular, easy to operate, and facilitate paralleling and maintenance. Given the increasing demand for power quality products, the design of power quality management cabinets is particularly important.

[0003] Power quality management products have diverse application scenarios, which place high demands on their application and installation dimensions and assembly schemes. In particular, for situations where the width of the on-site cabinet is small, existing power quality management products cannot meet the installation requirements. Therefore, the applicant proposes an embedded power quality management cabinet suitable for retrofitting sites with small widths. Summary of the Invention

[0037] Two upper support beams 3 are provided between the third right side beam 11 on the front and back sides, and two lower support beams 4 are provided between the fourth right side beam 11 on the front and back sides. Two symmetrically arranged module fixing beams 7 are provided between the upper support beam 3 and the lower support beam 4 on the same side.

The top of the module fixing beams 7 is provided with an upper side fixing hole 7.1, and the bottom of the module fixing beams 7 is provided with a lower side fixing hole 7.2 for connecting the power management module 9.

[0038] An upper limit bracket 5 is provided below the third right side beam 11 from top to bottom, and a lower limit bracket 6 is provided above the fourth right side beam 11 from top to bottom. Both the upper limit bracket 5 and the lower limit bracket 6 are L-shaped limit plates. The two upper limit brackets 5 are arranged symmetrically with their openings facing downwards, and the two upper limit brackets 5 are arranged symmetrically with their openings facing upwards. Thus, a first module area is formed between the module fixing beam 7 near the front of the cabinet frame 1 and the upper limit bracket 5 and the lower limit bracket 6, where a power management module 9 is placed.

[0041] Working principle:

[0042] This utility model relates to an embedded power quality management cabinet. First, the embedded structure is divided into two identical compartments according to the thickness of the power quality module. Based on the compartment division, a module fixing beam is provided in the middle of the cabinet. Upper and lower limit brackets are installed on both sides of the cabinet. The power quality module is fixedly installed by connecting the side ears of the power quality module to the screw holes of the module fixing beam with screws. In addition, the left and right side beams (crossbeams) inside the cabinet are made of galvanized sheet metal, and the hardness and strength can meet the installation requirements.

[0043] Secondly, based on the on-site installation capacity or the production installation capacity, determine the required number of installation modules and adjust the height of the embedded structure inside the cabinet to meet the needs of different users. The number of modules can vary from 1 to 3, offering good expandability, with each compartment being independent and ensuring adequate heat dissipation and ventilation. The modular installation structure facilitates inspection, maintenance, and replacement in case of module damage or malfunction.

[0044] This utility model discloses an embedded power quality control cabinet. The embedded structure is fixed to the cabinet body using screws, while individual power quality modules are secured by connecting screw holes on their sides to the screw holes of the embedded structure. The embedded structure of the power quality control module is suitable for project renovation sites where the cabinet body needs to be retained, and where the cabinet size is small, enabling rapid module installation and quick deployment. The embedded structure of the power quality control module is also suitable for tasks where the production and assembly schedule for the entire cabinet is tight, avoiding delays and improving production efficiency.

[0045] The embedded structure of the power quality management module is galvanized and modularly installed, providing both robust mechanical strength and reliable grounding continuity.

[0046] The embedded structure of the power quality management module has relatively independent functions for each compartment, and independent ventilation to ensure good ventilation and normal heat dissipation of the power quality management module; in case of failure or damage to the power quality management module, it is convenient to inspect, maintain and replace.

[0047] The power quality management module has a highly scalable embedded structure, allowing for the addition of modules or plug-ins, support for customized functions, and device integration.

[0048] The embedded structure of the power quality management module is simple and suitable for the orderly distribution of electrical equipment and lines. The standard wiring is usually not easy to be connected incorrectly or damaged, which is beneficial for the diagnosis and maintenance of the lines.

[0049] The power quality management module features an embedded structure, facilitating easy cable entry and exit within the cabinet. This effectively prevents damage to the cable sheath at sheet metal bends. It can accommodate power management modules of varying capacities within a small space, offering strong structural versatility and flexible assembly.

[0050] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
