Technical Field

[0001] This utility model relates to the field of frequency converter technology, and in particular to a frequency converter stacked busbar. Background Technology

[0002] A frequency converter (VDC) is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of its power supply. A VDC mainly consists of a rectification unit (AC to DC), a filtering unit, an inverter (DC to AC), a braking unit, a drive unit, a detection unit, and a microprocessor unit. The VDC adjusts the output voltage and frequency by switching its internal IGBTs, providing the required power voltage according to the motor's actual needs, thereby achieving energy saving and speed regulation. When using a VDC, laminated busbars are required. Laminated busbars are common components in high-current-density power supply systems, effectively reducing voltage spikes generated when semiconductor devices are switched on or off.

[0003] The existing laminated busbars require professional technicians to use bolts during installation, which takes a lot of time to install precisely, resulting in increased time and labor costs. At the same time, the disassembly of the laminated busbars is relatively complicated during maintenance, which leads to inconvenience in installation and disassembly. Utility Model Content

At the same time, the disassembly of laminated busbars is relatively complicated during maintenance, resulting in inconvenience in installation and disassembly. Therefore, a laminated busbar for frequency converters is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a frequency converter stacked busbar, including a stacked busbar assembly, a mounting component is provided at the bottom of the stacked busbar assembly, a limit component is provided on the mounting component, the mounting component includes a fixing frame, mounting grooves are symmetrically mounted on the top of the fixing frame, mounting blocks are slidably mounted inside the mounting grooves, fixing plates are symmetrically mounted at one end of the mounting grooves, a limit plate is movably mounted inside the fixing plate, a mounting plate is mounted on the side of the mounting groove, a limit rod passes through the inside of the mounting plate, a spring is provided on the outside of the limit rod, and one end of the limit rod passes through the inside of the limit plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by sliding the mounting block inside the mounting groove, the installation of the laminated busbar assembly is facilitated. Then, the moving limiting plate slides inside the fixed plate, which helps to limit the mounting block. By pulling the limiting rod to the side, the spring is compressed. When the limiting plate moves to the corresponding position, the limiting rod is released, causing the spring to extend, thereby driving one end of the limiting rod to pass through the interior of the limiting plate, which helps to limit the limiting plate and ensures the stability and reliability of the laminated busbar assembly installation. It eliminates the need for professional personnel to use a large number of bolts for installation, shortens the installation time, and facilitates the quick docking of the laminated busbar assembly with the frequency converter, thereby improving installation efficiency. At the same time, it facilitates the maintenance and repair of the laminated busbar assembly, improves maintenance efficiency, and extends the service life of the laminated busbar assembly.

[0013] 2. In this utility model, the movable fastener moves inside the guide frame, thereby causing the fastener to be engaged on both sides of the stacked busbar assembly. This helps to further limit the stacked busbar assembly and ensures the stability and reliability of the stacked busbar assembly installation. The elastic tension of the tension spring ensures that the fastener is stably engaged on both sides of the stacked busbar assembly. The friction pad adheres to the stacked busbar assembly, which helps to increase the friction with the stacked busbar assembly and further ensures the stability of the fastener's limiting effect on the stacked busbar assembly.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-6As shown, this utility model provides a technical solution: a frequency converter stacked busbar, including a stacked busbar assembly 1, an installation assembly 2 at the bottom of the stacked busbar assembly 1, a limit assembly 3 on the installation assembly 2, the installation assembly 2 including a fixing frame 201, an installation groove 202 symmetrically installed on the top of the fixing frame 201, an installation block 203 slidably installed inside the installation groove 202, a fixing plate 204 symmetrically installed at one end of the installation groove 202, a limit plate 205 movably installed inside the fixing plate 204, an installation plate 208 installed on the side of the installation groove 202, a limit rod 206 penetrating through the inside of the installation plate 208, a spring 207 provided on the outside of the limit rod 206, one end of the limit rod 206 penetrating through the inside of the limit plate 205, the installation block 203 installed at the bottom of the stacked busbar assembly 1, and a guide frame 301 installed on the fixing frame 201.

[0024] In this embodiment, the fixing bracket 201 is installed on the frequency converter. By sliding the mounting block 203 inside the mounting groove 202, the installation of the laminated busbar assembly 1 is facilitated. Then, the moving limiting plate 205 slides inside the fixing plate 204, which helps to limit the mounting block 203. By pulling the limiting rod 206 to the side, the spring 207 is compressed. When the limiting plate 205 moves to the corresponding position, the limiting rod 206 is released, causing the spring 207 to extend, thereby driving one end of the limiting rod 206 to pass through the interior of the limiting plate 205, which helps to limit the limiting plate 205. This ensures the stability and reliability of the installation of the laminated busbar assembly 1. It eliminates the need for professional personnel to use a large number of bolts for installation, shortens the installation time, and facilitates the quick docking of the laminated busbar assembly 1 with the frequency converter, thereby improving the installation efficiency. At the same time, it facilitates the maintenance and repair of the laminated busbar assembly 1, improves the maintenance efficiency, and extends the service life of the laminated busbar assembly 1.

[0025] Example 2: As Figures 1-6 As shown, the limiting component 3 includes two guide frames 301. A fastener 302 is movably installed inside the guide frame 301. The inner side of the fastener 302 is connected to the stacked busbar assembly 1. Multiple friction pads 303 are distributed on the inner side of the fastener 302. A connecting plate 305 is installed at the bottom of both the guide frame 301 and the fastener 302. A tension spring 304 is provided between the connecting plates 305. The stacked busbar assembly 1 includes a bottom insulating film 101. A negative busbar 102 is installed on the top of the bottom insulating film 101. A middle insulating film 103 is installed on the top of the negative busbar 102. A positive busbar 104 is installed on the top of the middle insulating film 103. An upper insulating film 105 is installed on the top of the positive busbar 104.

[0026] In this embodiment, after the stacked busbar assembly 1 is installed, the movable fastener 302 moves inside the guide frame 301, thereby causing the fastener 302 to be fastened on both sides of the stacked busbar assembly 1. This helps to further limit the stacked busbar assembly 1, ensuring the stability and reliability of the installation of the stacked busbar assembly 1. The elastic tension of the tension spring 304 makes the fastener 302 stably fastened on both sides of the stacked busbar assembly 1. The friction pad 303 adheres to the stacked busbar assembly 1, which helps to increase the friction with the stacked busbar assembly 1, further ensuring the stability of the fastener 302 in limiting the stacked busbar assembly 1. The stacked structure tightly combines the stacked busbar assembly 1 together, effectively utilizing space.

[0027] The working principle of this embodiment is as follows: In use, the fixing bracket 201 is first installed on the frequency converter. The mounting block 203 is slidably installed inside the mounting groove 202. Then, the moving limiting plate 205 slides inside the fixing plate 204, which helps to limit the mounting block 203. By pulling the limiting rod 206 to the side, the spring 207 is compressed. When the limiting plate 205 moves to the corresponding position, the limiting rod 206 is released, causing the spring 207 to extend. This allows one end of the limiting rod 206 to pass through the interior of the limiting plate 205, which helps to limit the mounting block 203. 5. Limiting the position facilitates the installation of the stacked busbar assembly 1. After the stacked busbar assembly 1 is installed, the movable fastener 302 moves inside the guide frame 301, thereby causing the fastener 302 to be locked on both sides of the stacked busbar assembly 1. Utilizing the elastic tension of the tension spring 304, the fastener 302 is stably locked on both sides of the stacked busbar assembly 1. The friction pad 303 adheres to the stacked busbar assembly 1, which helps to increase the friction with the stacked busbar assembly 1 and further ensures the stability of the fastener 302 in limiting the stacked busbar assembly 1.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
