Description

Technical Field

[0001] The utility model relates to the technical field of electronic circuits, in particular to a static reactive power generating device. Background Art

[0002] With the development of modern power systems, the management and compensation of reactive power has become particularly important. The imbalance of reactive power will not only affect the voltage stability of the power system, but also increase the transmission loss of the power grid and reduce the operation efficiency of the power grid. Therefore, static VAR compensation equipment (SVG) has been widely used in power systems as an effective means of reactive power compensation.

[0003] Traditional static VAR compensation equipment has some limitations in design and structure. First, the heat dissipation performance of the equipment is often insufficient, especially when running at high loads, the heat accumulation inside the equipment may cause the performance of components to deteriorate or even damage. Second, the installation and maintenance of the equipment is not convenient enough, requiring complex installation steps and professional maintenance personnel. In addition, traditional static VAR compensation equipment also has deficiencies in human-computer interaction and intelligent control, and it is difficult to meet the high requirements of modern power systems for reactive power compensation equipment.

[0004] Therefore, a static reactive power generating device is proposed. Utility Model Content

[0043] Reference Figure 1 and Figure 2 This specification provides a rack-mounted static reactive power generating device, including:

[0044] The shell is made of metal and has good thermal conductivity and mechanical strength. The shell is rectangular as a whole, with two symmetrical sides, a front and a back. The two symmetrical sides of the shell are fixedly connected with L-shaped rack ears to achieve stable installation of the equipment. The rack ear includes an integrally formed connection part and a mounting part. The connection part is installed on the side of the shell by fixing screws and extends to the front of the shell, so that the mounting part and the front of the shell are in the same plane. The mounting part is evenly spaced with several fixed mounting holes; at least one side of the shell is provided with several second heat dissipation ducts to increase the air circulation area; at least one heat dissipation fan is installed on the front of the shell, and the heat dissipation fan is covered with a heat dissipation net; the back of the shell is provided with main circuit input terminals, neutral line input terminals, ground line input terminals, current sampling input terminals, auxiliary circuit wiring terminals, and dial switches. These terminals are all standardized in design to facilitate user wiring operations. A second heat dissipation duct is also provided on the back of the shell, which forms convection with the side duct to improve heat dissipation efficiency. The second heat dissipation duct is covered with a heat dissipation net to ensure the temperature stability of the equipment during long-term operation.

[0045] The dip switch, auxiliary circuit wiring terminal, and current sampling input terminal are arranged in sequence from left to right at the upper left end of the back of the shell. This layout is convenient for users to adjust the equipment parameters and connect the auxiliary circuit. The main circuit input terminal and the neutral line input terminal are arranged in sequence from left to right at the upper right end of the back of the shell. The main circuit is the main energy input of the equipment, and its terminal is arranged at the upper right end to facilitate users to connect the main power line. The grounding wire input terminal is arranged at the lower right end of the back of the shell. As an important part of safety protection, the grounding wire terminal is arranged at the lower right end to comply with electrical safety regulations. The first heat dissipation duct is arranged on the left side of the grounding wire input terminal.

[0046] In order to improve the portability of the device and the convenience of user operation, handles are fixed symmetrically at both ends of the front of the shell. The corners of the handles are set as curved surfaces. This design not only increases the comfort of holding, but also avoids accidental injuries caused by right angles during transportation or movement. The material of the handle is also selected as non-slip and wear-resistant material to ensure stable grip in various environments.

[0047] In order to enhance the human-computer interaction capability of the device, a touch LCD screen is installed on the front of the shell. The screen not only has high-definition display function, but also supports multi-touch operation. Users can directly perform operations such as parameter setting and status viewing on the screen without the need for additional input devices, which greatly simplifies the operation process. The size and resolution of the display can be customized according to specific needs to meet the needs of different application scenarios.

[0050] The top surface of the shell is provided with main circuit input terminals, neutral line input terminals, ground line input terminals, current sampling input terminals, auxiliary circuit wiring terminals, and dip switches. The back of the shell is also provided with a second heat dissipation duct, which is covered with a heat dissipation net. These ducts provide additional dissipation paths for internal heat. Similarly, the heat dissipation duct is also covered with a heat dissipation net to enhance the heat dissipation effect.

[0051] The neutral line input terminal, ground line input terminal, main circuit input terminal, current sampling input terminal, auxiliary circuit wiring terminal, DIP switch, and second heat dissipation duct are arranged on the top surface of the shell from left to right. A variety of wiring terminals are arranged on the top surface of the shell to meet different electrical connection requirements. These terminals include the main circuit input terminal, neutral line input terminal, ground line input terminal, current sampling input terminal, and auxiliary circuit wiring terminal. The DIP switch is also located on the top surface of the shell and is used to set or adjust certain parameters or functions of the device. The wiring terminals and DIP switches are arranged from left to right, making the installation and maintenance process more convenient and intuitive.

[0052] The present invention has at least one of the following advantages:

[0053] 1. The wiring terminals of the equipment are clearly laid out and divided into areas according to functions, which facilitates users to perform quick and accurate wiring operations. The dip switches, auxiliary circuit wiring terminals, current sampling input terminals, main circuit input terminals, neutral line input terminals, and ground line input terminals are arranged in a certain order, reducing the risk of wiring errors.
