Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage frequency converters, and in particular to a high-voltage frequency converter that is easy to install. Background Art

[0002] High-voltage frequency converter is an electric energy control device. It is composed of transformer cabinet, power unit cabinet, control cabinet and bypass cabinet. The frequency converter is an electric energy control device that converts the industrial frequency power supply into another frequency by using the on-off function of power semiconductor devices. With the rapid development of modern power electronics and microelectronics technology, high-voltage and high-power frequency conversion speed regulation devices have continued to mature. The high-voltage problem that has been difficult to solve in the past has been well solved in recent years by connecting devices in series or units in series. Many devices and units are installed in a cabinet and connected in series.

[0003] In order to facilitate the installation of high-voltage inverters, the prior art has made many improvements to high-voltage inverters. For example, patent publication number CN217307527U discloses a high-voltage inverter that is easy to install, including a mounting seat, a mounting slot arranged on the upper side of the mounting seat, and an inverter body arranged in the mounting slot. A guide assembly is arranged at the bottom of the mounting slot, and a fixing assembly is arranged on one side of the mounting slot; the guide assembly includes a receiving slot, a hydraulic cylinder is arranged at the bottom of the receiving slot, and a carrier is arranged on the top of the piston rod of the hydraulic cylinder. A first guide roller, a second guide roller, and a third guide roller are arranged in the carrier for rotation in sequence, one end of the first guide roller is connected to a drive motor located on one side surface of the adjustment box, and one end of the first guide roller is provided with a driving pulley, the driving pulley is connected to a double-row pulley through a synchronous belt, and the double-row pulley is connected to a driven pulley through a synchronous belt. The utility model can quickly lift and guide the inverter body, and the installation operation is convenient and the fixing stability is good.

[0004] While the aforementioned patent has significant benefits, it still suffers from the following deficiencies in practical operation: During installation, the high-voltage inverter must be installed in a designated distribution room. Since this room lacks lifting equipment, the larger cranes used in existing technologies cannot reach the room for operation. Consequently, the high-voltage inverter is often manually lifted into the room or moved onto a mobile cart. Due to its large size, fully lifting it off the ground is difficult, increasing the installer's workload. Furthermore, the high-voltage inverter requires numerous components to be installed and connected in series, and the limited space within the cabinet limits the installer's mobility. These two deficiencies reduce the efficiency of high-voltage inverter installation. Therefore, there is an urgent need for a high-voltage inverter that is easy to install and addresses the shortcomings of existing technologies. Summary of the Invention

The first transmission wheel 7 and the number of second transmission wheels 8 are staggered, and a transmission belt 10 is sleeved between the clamping grooves 9.

[0043] Specific implementation method in this embodiment: When the inverter body needs to be installed, the entire cabinet 1 is moved to the outside of the distribution room to be installed using transportation equipment, and the cabinet 1 is placed on a relatively flat ground using lifting equipment. The installer installs the mobile unit 4 at the lower end of the cabinet 1, uses the mobile unit 4 to move the cabinet 1 to the location to be installed, disassembles the mobile unit 4, and fixes the cabinet 1 to the ground installation position. When it is necessary to install the electronic control product in the cabinet 1, by starting the drive motor 6, the output end of the drive motor 6 drives the first transmission wheel 7 to rotate. When the first transmission wheel 7 rotates, it drives several second transmission wheels 8 to rotate in the same direction through the transmission belt 10. After the second transmission wheel 8 rotates, it drives the rotating screw 5 to rotate. When the rotating screw 5 rotates, it drives the mobile mounting plate 2 to move in the cabinet 1. After the mobile mounting plate 2 moves to the opening position of the cabinet 1, the drive motor 6 is stopped, so that the installer can install the electronic control product on the mobile mounting plate 2. After installation, the drive motor 6 is reversed to move the mobile mounting plate 2 to the starting position, thereby improving the efficiency of installing the inverter body.

[0044] Among them, the above-mentioned drive motor 6 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The drive motor 6 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or chemical power supply) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0045] As a technical optimization solution of the present invention, a side of the movable mounting plate 2 close to the cabinet door is connected to a symmetrical and adaptive side mounting plate 11, and the opposite back side of the side mounting plate 11 is against the inner wall of the cabinet body 1.

[0046] Specifically, the number of electronic control products that can be installed on the movable mounting plate 2 is limited. The electronic control products can be installed on the side mounting plate 11 to increase the installation area. At the same time, the side mounting plate 11 can be moved on the through rod 12, so that multiple installers can install them at the same time. After the electronic control products on the side mounting plate 11 are installed, the side mounting plate 11 is moved, and the side mounting plate 11 is moved on the through rod 12. The side mounting plate 11 moves to one side and is against one side of the movable mounting plate 2. The limit ring 14 is threadedly connected to the end of the through rod 12, and after tightening, the wires of the electronic control products are connected to improve the efficiency of the overall installation of the inverter body.

At this time, the fixed plate 19 squeezes the lower pressure plate 24 upward again, and the fixed plate 19 is disengaged from one end of the limit rod 27. At this time, the second spring 32 pushes the limit rod 27 to move in the direction of the insertion slot 23, and one end of the limit rod 27 is disengaged from the limit groove 29. Remove the moving unit 4, reverse the adjusting stud 20, and lower the cabinet 1 to the position to be installed for installation, which reduces the overall labor intensity of the installer.
