Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of high and low voltage complete sets of equipment, and particularly relates to a ventilation and filtration component of high and low voltage complete sets of equipment with a self-cleaning function. Background Art
[0002] With the development of modern industry, the widespread application of non-linear loads and electronic devices in the power system has led to the emergence of various power quality problems, such as harmonics, voltage fluctuations, and flicker. These problems not only affect the stability of the power system but may also cause a decrease in the efficiency of electrical equipment, a shortening of the service life, and an increase in the failure rate. To solve the above problems, traditional passive filters are widely used to suppress harmonic components in the power grid. However, passive filters have some inherent limitations. For example, they can only effectively filter specific frequency harmonics, and their performance is easily affected by changes in power grid parameters. In addition, the design of passive filters is complex, requires a large installation space, and performs poorly in dealing with dynamically changing loads.
[0003] In view of the deficiencies of passive filters, active power filters have gradually received attention as a more flexible and efficient solution. The APF improves power quality by continuously monitoring the grid current and generating corresponding compensation currents to cancel out harmonic components. Although the APF performs well in improving power quality, the heat generated during its operation also needs to be effectively managed.
[0004] In summary, the present invention combines the technology of the APF in regulating voltage and current harmonics with an innovative ventilation and filtration component, aiming to provide a comprehensive solution that can ensure the long-term stable operation of the equipment.

The water supply pipe 302 passes through the wall surface of the housing 100 and is connected to an external water source. The water collection tray 303 is located below the filtering unit 200 and is inclined. The timing controller 502 controls the solenoid valve 304 to open, so that water is evenly sprayed onto the filter mesh through the spray head 301 to achieve automatic cleaning. The water supply pipe 302 ensures the supply of cleaning water, and the water collection tray 303 collects and discharges the sewage after cleaning the filter mesh from the housing 100;
[0039] The active power filter 400 is fixed to the bottom of the housing 100 near the air inlet 101 through an insulating bracket and is directly connected to the power input end through a wire, protecting the electrical components from the environment and optimizing the heat dissipation effect at the same time;
[0040] The control panel 500 is integrated with a wireless communication module 501, a timing controller 502, an alarm system 503, and a monitoring system 504. The wireless communication module 501 is used for data exchange and remote monitoring.

When an abnormal situation is detected (such as filter mesh blockage), the alarm system 503 provides an alarm feedback. The monitoring system 504 monitors the environmental parameters in real time and feeds the data back to the control panel 500.
[0041] Specifically, the wireless communication module 501 supports at least one communication protocol among Wi-Fi, Bluetooth, or ZigBee to achieve data exchange with mobile devices or a central control system. The alarm system 503 is configured with an audible and visual alarm and can notify maintenance personnel via text message or email. The audible and visual alarm is fixed to the top of the housing 100. The monitoring system 504 is connected to an air quality sensor 505, a humidity sensor 506, etc., to monitor environmental parameters in real time and feed the data back to the control panel 500. The air quality sensor 505 and the humidity sensor 506 are arranged inside the housing 100.
[0042] Further, the dehumidification cover 104 is fixed around the air outlet 102 of the housing 100 by means of bolt fastening, and a dehumidification layer is added inside it to prevent moist air from entering the device. The water collection tray 303 is inclined, and a drain hole is provided at its lower end leading directly to the outside of the housing 100. The spray head 301 is inclined, and the water outlet ends of the spray head 301 face the top and the middle of the filtration unit 200 respectively. The water supply pipe 302 is equipped with a solenoid valve 304, and the solenoid valve 304 is connected to the timing controller 502;
[0043] The front of the control panel 500 is embedded with a display 507 and buttons 508, and a speaker 509 is arranged at the bottom of the control panel 500. The display 507 is used to display the current status and operation information. The buttons 508 facilitate manual operation and adjustment of settings by the user. The speaker 509 plays sound alarms or other prompt sounds. The control panel 500 further includes a storage module 510 and a data analysis module 511. The storage module 510 is used to record historical operation data and alarm records. The data analysis module 511 generates a trend graph and a health status report based on the real-time data of the monitoring system 504 and can send the analysis results to mobile devices or a central control system via the wireless communication module 501.
[0044] The specific operation steps of this embodiment are as follows:

[0051] Working Principle
[0052] This embodiment is based on an integrated high and low voltage complete set of equipment ventilation and filtration system, aiming to achieve efficient air filtration and automatic cleaning. First, air enters from the air inlet with louvers embedded on one side of the bottom of the housing. When passing through the filtration unit 200, particulate matters of different particle sizes are intercepted step by step to ensure the cleanliness of the output air; among them, gaps are left between each layer of filters to optimize air circulation. In order to maintain the effectiveness of the filtration unit 200, the system is equipped with a set of automatic cleaning components 300, including a nozzle 301, a water supply pipe 302 and a water collecting tray 303. The timing controller 502 controls the opening of the solenoid valve 304 according to a preset cycle or sensor feedback, so that water flows through the flexible pipe to the nozzle 301 to wash the filter, and the sewage flows into the inclined water collecting tray 303 and is discharged through the drain holes. In addition, the active power filter 400 is fixed at the bottom of the housing near the air inlet, responsible for regulating voltage and current harmonics to ensure the stable operation of the electrical system. The whole process is intelligently managed by a control panel 500 integrating a wireless communication module 501, a timing controller 502, an alarm system 503 and a monitoring system 504, which can monitor air quality and humidity in real time, feedback data to users, and support remote communication functions for timely early warning and maintenance notification.
