It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a status monitoring device for a pole-mounted reactive power compensation device, including a device housing 1. A status display panel 3 is fixedly connected to the front of the device housing 1, and a display screen 31 is embedded in the front of the status display panel 3. A status indicator light 33 is provided above the display screen 31. Multiple air inlets 11 are opened through the outer wall of the rear of the device housing 1. A cooling channel 2 is embedded in the outer wall of the device housing 1, and both ends of the cooling channel 2 are fixedly connected to connecting pipes 21. An exhaust port 18 is opened through the bottom surface of the device housing 1. A cooling fan 17 is installed on the inner bottom surface of the device housing 1 and is located above the exhaust port 18. A monitoring module 15 is installed on the inner wall of the device housing 1. The monitoring module 15 includes a signal conditioning circuit, a high-precision AD converter, and a filtering circuit. The signal conditioning circuit amplifies and reduces noise of the weak analog signal collected by the sensor; the AD converter... The converter converts analog signals into digital signals to ensure data acquisition resolution; the filter circuit filters out power grid interference signals to improve data accuracy; it also includes a microprocessor, which, together with the crystal oscillator circuit and reset circuit, forms a minimum control system as the core of the module's operation, performing electrical parameter calculations, fault logic judgments, and compensation strategy preprocessing.

[0019] The specific settings and functions of this embodiment are described in detail below. The display screen 31 displays electrical parameters such as voltage, current, and power factor, as well as the equipment's operating mode in real time, clearly presenting the equipment's operating status. The status indicator 33 uses different colors to correspond to the equipment's normal operation, abnormal warning, and fault shutdown status, quickly transmitting equipment operating condition signals. The air inlet 11 introduces cold air into the equipment, forming a heat dissipation airflow channel and providing an air source for the heat dissipation system. The cooling channel 2, together with the connecting pipe 21, forms a circulating heat dissipation path, using fluids such as coolant to carry away the heat generated by internal components, enhancing the heat dissipation effect. The connecting pipe 21 connects the two ends of the cooling channel 2, ensuring the circulation of coolant and ensuring the continuous operation of the heat dissipation system. The exhaust port 18 serves as a hot air exhaust channel, forming an airflow circulation with the air inlet 11 to promptly exhaust internal hot air. The cooling fan 17 accelerates the airflow at the exhaust port 18, improving the efficiency of hot air exhaust and further reducing the internal temperature of the equipment. The monitoring module 15 serves as the data acquisition core, collecting grid electrical parameters and equipment operating data in real time, providing basic data support for subsequent processing and feedback.

[0020] Example 2: Figure 1 - Figure 5 As shown, a wiring backplate 12 is fixedly connected to the back of the equipment housing 1. A wiring panel 13 is installed on one side of the wiring backplate 12, and a display interface 14 is provided on the other side of the wiring backplate 12. The display interface 14 is installed on the back of the equipment housing 1. A control button 32 is provided below the display screen 31. The control button 32 and the status indicator light 33 are both installed on the front of the status display panel 3. A filter cotton 16 is installed on the inner wall of the equipment housing 1. The filter cotton 16 is located inside the air inlet 11. A telescopic slide rail 4 is installed on the bottom surface of the equipment housing 1. The telescopic slide rail 4 includes a movable plate 41. The top surface of the movable plate 41 is fixedly connected to the bottom surface of the equipment housing 1. The telescopic slide rail 4 also includes a base plate 42, a damper 43, a first limit block 44, and a second limit block 45. The movable plate 41 is slidably connected to the inner wall of the base plate 42. The second limit block 45 is fixedly connected to one end of the base plate 42. The first limit block 44 is fixedly connected to the other end of the base plate 42. The damper 43 is fixedly connected to the tail end of the movable plate 41.

[0021] The overall implementation achieves the following effects: the wiring panel 13 centrally houses the wiring terminals, facilitating connection between the device and external power grids and communication lines, and simplifying wiring operations; the display interface 14 enables signal transmission between the display screen 31 and the internal control module, ensuring normal data display on the display screen 31; the filter cotton 16, placed inside the air inlet 11, filters dust and impurities in the air entering the device, preventing dust from adhering to the device surface and affecting heat dissipation and service life; the sliding cooperation between the movable plate 41 and the base plate 42 facilitates the overall installation and fixation of the device and subsequent disassembly and maintenance; the damper 43 buffers the impact force when the movable plate 41 slides, preventing excessive sliding from causing equipment collision damage, and making the sliding process smoother; the limit block 1 44 and limit block 2 45 limit the sliding stroke of the movable plate 41, preventing the movable plate 41 from falling off the base plate 42 and ensuring the safety of the sliding structure.

[0022] The device's operation and working principle are as follows: After the device is started, the monitoring module 15 collects real-time electrical parameter data such as voltage, current, and reactive power of the power grid and transmits the data to the internal control module for processing. The processed data is then transmitted to the display screen 31 for real-time display through the display interface 14. Simultaneously, the control module judges the device's operating status based on the data and provides feedback on the operating status through the status indicator 33. During device operation, the cooling fan 17 starts, and cool air enters the device through the air inlet 11. After being filtered by the filter cotton 16, the air flows over the surface of the components, absorbs heat, and is then discharged through the exhaust port 18. The coolant in the cooling channel 2 circulates through the connecting pipe 21, helping to remove heat and maintain a stable internal temperature. Maintenance personnel can adjust the device parameters through the control button 32 or troubleshoot and maintain the device based on the feedback from the status display panel 3.
