Description

Technical Field

[0001] The utility model relates to the technical field of overvoltage suppression components, in particular to a quick-installed PT overvoltage suppression component. Background Art

[0002] PT, or voltage transformer, overvoltage refers to the long-term voltage fluctuation phenomenon that the root mean square value of the AC voltage under the power frequency increases, exceeds 10% of the rated value, and lasts for more than 1 minute; the occurrence of overvoltage is usually the result of the moment of load switching. It occurs when the inductive or capacitive load is connected or disconnected during normal use. During the installation process of PT overvoltage, a PT cabinet is required to install it. However, since the PT cabinet is usually provided with heat dissipation holes, when the PT cabinet is not in working state, the external dust enters the interior of the PT cabinet through the heat dissipation holes. In addition, the PT cabinet needs to be quickly installed and disassembled with the outdoor base during the installation process. The PT overvoltage suppression component in the prior art does not have the functions of dustproof and quick assembly and disassembly.

[0003] It is known that a switch arc extinguishing, detuning and overvoltage suppression cabinet device (publication number CN215267318U) is disclosed. This switch arc extinguishing, detuning and overvoltage suppression cabinet device is connected by buffer connectors between the top of the suppression cabinet body and the rain shield and between the bottom of the suppression cabinet body and the base to alleviate the impact of external impact on the suppression cabinet body. At the same time, a cooling component is provided. When the external temperature is too high, the air entering the cabinet is cooled by the cooling component to prevent the internal temperature of the cabinet from being too high and causing the electronic components in the cabinet to burn out. In addition, an electric heating component is installed on the side wall inside the cabinet to prevent the external temperature from being too low and causing the steam inside the cabinet to condense on the side wall and cause safety hazards. However, although the above technical scheme can play a good cooling role.

[0004] At present, since the PT cabinet is usually provided with heat dissipation holes, when the PT cabinet is not in working state, external dust enters into the interior of the PT cabinet through the heat dissipation holes. The device is not provided with relevant dustproof structure, which leads to the reduction of service life of the PT cabinet. In addition, the PT cabinet needs to be quickly installed and disassembled with the outdoor base during installation. The device is not provided with relevant structure for quick installation and disassembly, which leads to the increase of installation cost. For this reason, we provide quick-install PT overvoltage suppression components. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a quick-install PT overvoltage suppression component, which solves the problem that the service life of the PT cabinet is reduced due to the lack of a relevant dustproof structure in the device and the problem that the device is not provided with a relevant structure that is easy to quickly install and disassemble, thereby increasing the installation cost.

[0006] To achieve the above purpose, the utility model is implemented by the following technical solutions: a quick-installed PT overvoltage suppression component, a PT overvoltage suppression component box, a mounting seat is arranged at the bottom of the PT overvoltage suppression component box, an assembly mechanism is arranged at the middle of the top of the mounting seat, a mounting plate B is arranged at one end of the assembly mechanism, a screw rod C is connected through one end of the mounting plate B, and a screw rod A is connected through the other end of the mounting plate B, a mounting plate A is arranged at the middle of one end of the mounting plate B, a PT overvoltage suppression component box is arranged at the middle of one end of the mounting plate A, and a screw rod C is connected through one end of the mounting plate B, and a screw rod A is connected through one end of the mounting plate A.

[0007] Preferably, a fixing rod is provided at the middle of the top end of the PT overvoltage suppression component box, and a rain shield is provided at the middle of the top end of the fixing rod.

[0008] Preferably, the front end of the PT overvoltage suppression component box is movably connected to a cabinet door, and a handle is provided in the middle of one end of the cabinet door.

[0009] Preferably, a cooling component is disposed inside one end of the mounting seat.

[0010] Preferably, a support base is provided at the bottom of the mounting seat, and support feet are provided at four corners of the bottom of the support base.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. The utility model uses the PT overvoltage suppression component box when it is not in use, and starts the drive motor to rotate it. The drive motor drives the rotation of gear A during the rotation process, and gear A drives the rotation of gear B during the rotation process. Gear B drives the rotation of the threaded rod during the rotation process. The threaded rod is threadedly connected to the dustproof plate. The threaded rod drives the dustproof plate to move toward one end of the drive motor during the rotation process. When the dustproof plate moves toward one end of the drive motor, it drives the dustproof hole to stagger with the heat dissipation hole inside the cooling component, thereby achieving a dustproof effect and thus extending the service life;

[0014] 2. The utility model places the PT overvoltage suppression component box in the middle of the top of the mounting base, then overlaps the connection hole inside the mounting plate A with the connection hole inside the PT overvoltage suppression component box, overlaps the connection hole inside the mounting plate B with the connection hole inside the mounting base, and then inserts the screw B into the hole inside the mounting plate A and the hole inside the PT overvoltage suppression component box respectively, and inserts the screw C and the screw A into the hole inside the mounting plate B and the hole inside the mounting base respectively, and then fixes them, thereby reducing the installation cost.
