Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated substations, and specifically provides a high-protection high-low voltage prefabricated substation. Background Art

[0002] In the power system, as a key node for power distribution and conversion, the performance and reliability of high-low voltage prefabricated substations directly affect the quality and stability of power supply. However, in terms of protection, especially in the field of moisture protection, there are many problems to be solved urgently in existing prefabricated substations.

[0003] Traditional high-low voltage prefabricated substations have relatively simple and weak moisture-proof measures. Generally, only some basic sealing structures are relied on to prevent the intrusion of external moisture. For example, rubber sealing strips are simply used to seal the door seams and window seams of the box body. However, with the passage of time and the change of environmental conditions, these sealing measures are prone to aging and failure.

[0004] When moisture enters the substation interior, it will condense into water droplets on the surface of electrical equipment, causing serious damage to high-low voltage equipment. For high-voltage equipment, moisture may cause the insulation performance of insulation components to decline, increasing the risk of high-voltage discharge and short circuit.

[0005] In addition, existing prefabricated substations lack systematicness and intelligence in moisture-proof design. Most substations only rely on passive moisture-proof measures without an active moisture monitoring and elimination mechanism. For example, when the humidity inside the substation gradually rises, it cannot be detected in time and effective measures cannot be taken for treatment. This may lead to the continuous accumulation of moisture in the substation until obvious damage to the equipment is found, and at this time, certain economic losses and potential safety hazards have been caused.

[0006] In view of this, this application is specifically proposed. Content of the Utility Model

[0007] The purpose of the utility model is to provide a high-protection high-low voltage prefabricated substation to solve the problems raised in the above background art.

[0008] To solve the above technical problems, the utility model provides a high-protection prefabricated substation for high and low voltages, which includes a cabinet body. A louver assembly is installed on the side wall of the cabinet body. A partition is fixedly installed inside the cabinet body. The interior of the cabinet body is divided into a dehumidification space and an installation space by the partition. A first through hole communicating the dehumidification space and the installation space is opened on the partition. A sealing cover is installed on the inner side wall of the cabinet body. A ventilation fan is slidably installed inside the sealing cover. A second electric push rod is fixedly installed inside the sealing cover. The telescopic end of the second electric push rod is fixedly connected to the side wall of the ventilation fan. A second through hole and a third through hole communicating with the cabinet body are opened on the sealing cover. An air pipe is installed on the bottom wall of the sealing cover.

[0009] Further, the ventilation fan includes a sliding plate slidably installed inside the sealing cover. A driving motor is installed on the sliding plate. The driving end of the driving motor is fixedly connected with a fan blade. The telescopic end of the second electric push rod is fixedly connected to the side wall of the sliding plate.

[0010] Further, a dehumidifier is installed inside the dehumidification space. There are multiple dehumidifiers.

[0011] Further, a pair of split cabinet doors are hinged on the front side of the cabinet body. A locking member is arranged on the cabinet doors. The locking member is closed with the cabinet body through the cabinet doors.

[0012] Further, ventilation openings are symmetrically arranged on the left and right on the side wall of the cabinet body. The louver assembly is installed inside the ventilation openings.

[0013] Further, the louver assembly includes a window frame installed inside the ventilation opening. A plurality of rotating shafts are rotatably installed at equal intervals on the window frame. A folding leaf is fixedly installed on the rotating shaft. The end of the folding leaf extending outside the window frame is fixedly installed with a transmission gear. A transmission rack meshing with the transmission gear is slidably installed on the side wall of the window frame. A first electric push rod for pushing the transmission rack to slide vertically is fixedly installed on the window frame.

[0014] Further, the folding leaf can rotate synchronously with the rotating shaft. Two adjacent folding leaves fit with each other.

[0015] Further, a humidity sensor is fixedly installed on the inner top wall of the cabinet body. A controller is installed on the inner side of the cabinet body. The dehumidifier, the humidity sensor, the driving motor, the second electric push rod and the first electric push rod are all electrically connected to the controller.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. In this utility model, the controller can receive the humidity value inside the cabinet measured by the humidity sensor. When the humidity value received by the controller is greater than the first preset value and less than the second preset value, it can trigger the drive motor to drive the fan blade to rotate, so that the natural air outside enters the cabinet through the louver assembly arranged on the left side wall of the cabinet, and then is discharged through the louver assembly on the right side wall of the cabinet. It can effectively utilize the dry air in the natural environment to reduce the humidity inside the cabinet, without consuming additional energy for dehumidification, thus reducing energy consumption.

[0018] 2. In this utility model, the second electric push rod pushes the sliding plate to move to the right and triggers the dehumidifier to start. During the movement of the sliding plate, the second through hole and the third through hole are opened, so that the wet air inside the cabinet enters the dehumidification space through the first through hole, and then the air entering the dehumidification space is condensed and dehumidified by the dehumidifier. The dehumidified air enters the second through hole through the ventilation pipe, and then is discharged through the second through hole to realize the internal circulation of the air inside the cabinet, so as to reduce the ventilation between the inside of the cabinet and the outside. By circulating the air inside the cabinet and condensing it through the dehumidifier, the effect of condensation dehumidification can be achieved. Timely humidity monitoring and treatment can prevent equipment short - circuit caused by moisture, improve the protection performance of the substation, and avoid the economic losses brought by production interruption.
