Technical Field

[0001] The present invention relates to the technical field of power system safety protection devices, and in particular to a power system safety intelligent protection device. Background Art

[0002] At present, the distribution automation system is an integrated system for remote real-time monitoring, coordination and control of distribution network equipment. It is an emerging technology developed in recent years and is a comprehensive application of modern computer technology and communication technology in the monitoring and control of distribution networks. In the distribution automation system, it is inevitable to set up power automation distributors in the field, and power automation distributor protection devices are essential.

[0003] The existing power system safety protection device is used by centrally arranging the electrical components in the power system in an explosion-proof cabinet, and protecting the electrical components through the cabinet. However, since the cabinet is usually placed on the spot, there is a situation where water enters the explosion-proof cabinet due to heavy rain, which in turn affects the electrical components in the cabinet, resulting in poor waterproof protection performance. In addition, during the use of the existing power system safety protection device, moisture will enter the cabinet and corrode the electrical components, thereby affecting the entire power system, not only resulting in a shorter service life of the electrical components, but also resulting in poor moisture-proof protection performance of the device. Therefore, an intelligent power system safety protection device is urgently needed to solve the above problems. Summary of the invention

During use, the exhaust fan discharges the heat in the cabinet, thereby dissipating the heat of the electrical component. The servo motor drives the stud to rotate, thereby causing the screw sleeve to move under the action of the thread and the guide sleeve and the guide column, driving the drying frame to move up and down in the cabinet, thereby allowing the desiccant to fully absorb the moisture in the cabinet to prevent moisture from corroding the electrical components. , ensure the service life of the electrical components, and provide moisture-proof protection for the electrical components. When rainwater flows back into the distribution station, the float will move in the buoy under the action of rainwater, and the float will eventually apply external force to the push switch to close it. The main controller can detect the closing signal and control the drive motor to work. The drive motor drives the screw to rotate, so that the screw block drives the bearing seat downward under the action of the thread, guide rod and guide block, so that the bearing seat supports the cabinet, increases the gap between the bottom end of the cabinet and the bottom surface, and prevents it from being flooded, thereby providing waterproof protection for the electrical components.
