Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pole-mounted switches, and in particular to a pole-mounted switch based on a photovoltaic panel and a method, device and medium thereof. BACKGROUND

[0002] A pole-mounted switch is arranged on a power pole in an outdoor environment, and the pole-mounted switch is used to provide operation protection for a power system in which the power pole is located. There are many clean energy sources in the outdoor environment. In order to reduce power consumption of the pole-mounted switch on the power system, a photovoltaic panel is arranged on the power pole, and the photovoltaic panel can supply power to the pole-mounted switch, thereby reducing power consumption of the pole-mounted switch.

[0003] However, when the photovoltaic panel is arranged on the power pole, an installation position and a support are additionally determined for installation, and the photovoltaic panel is supported and fixed by the support. The power pole has been originally installed with devices such as a pole-mounted switch, a lightning arrester, a knife switch and a power distribution terminal. It is difficult to determine an installation position that does not interfere with other devices on this basis, and it is easy to cause the devices on the power pole to be crowded, which is not convenient for subsequent maintenance of the devices on the power pole. In addition, the support has a large volume and a large windward area, is greatly affected by the harsh environment in the outdoor environment, and is easy to increase the wind load risk of the power pole, thereby threatening the stability of the entire power pole.

[0021] This invention provides a pole-mounted switch based on a photovoltaic panel, and its method, apparatus, and medium. The pole-mounted switch includes: three epoxy poles and a mechanism housing. The three epoxy poles are equally spaced on the upper surface of the mechanism housing. The mechanism housing includes a housing, a charging controller, and a battery. The charging controller and the battery are located inside the housing, and the charging controller is electrically connected to the battery. The housing includes a top plate with at least two mounting holes. Two photovoltaic modules are located between two adjacent epoxy poles. The photovoltaic module includes a photovoltaic panel and a pressure plate. Two photovoltaic panels are connected in parallel and electrically connected to the charging controller and the battery, respectively. Each photovoltaic panel includes a glass plate and a fixed frame. The glass plate is fixed inside the fixed frame, which is located inside the mounting through hole. The upper surface of the photovoltaic panel is flush with the upper surface of the top plate. The pressure plate abuts against the lower surface of the fixed frame. A hexagonal stud is vertically fixed to the lower surface of the top plate, and the screw end of the hexagonal stud is welded to the top plate. The pressure plate is placed on the upper surface of the head end of the hexagonal stud. According to the technical solution of the present invention, the pressure plate applies upward pressure to the fixed frame, causing the fixed frame to be pressed into the mounting through hole of the mechanism box. The fixed frame is used to fix the glass plate, thereby realizing the integrated integration of the photovoltaic panel and the mechanism box, and the integrated integration of the pole-mounted switch and the photovoltaic panel. That is, there is no need to set up additional brackets on the utility pole to support and fix the photovoltaic panel, which does not have an excessive impact on the stress structure of the utility pole and reduces the wind load risk of the utility pole.

[0022] First, refer to Figure 1 and Figure 2 The pole-mounted switch 100 based on a photovoltaic panel 410 provided in this application embodiment includes: Three epoxy poles 200 and a mechanism box 300 are installed at equal intervals on the upper surface of the mechanism box 300. The mechanism box 300 includes a housing, a charging controller and a battery. The charging controller and the battery are located inside the housing. The charging controller is electrically connected to the battery. The housing includes a top plate 310. The top plate 310 is provided with at least two mounting through holes. Two photovoltaic modules 400 are located between two adjacent epoxy poles 200. Each photovoltaic module 400 includes a photovoltaic panel 410 and a pressure plate 420. The two photovoltaic panels 410 are connected in parallel and electrically connected to a charging controller and a battery, respectively. Each photovoltaic panel 410 includes a glass plate 411 and a fixed frame 412. The glass plate 411 is fixed inside the fixed frame 412, which is located inside the mounting through hole. The upper surface of the photovoltaic panel 410 is flush with the upper surface of the top plate 310. The pressure plate 420 abuts against the lower surface of the fixed frame 412. A hexagonal stud 430 is vertically fixed to the lower surface of the top plate 310. The screw end of the hexagonal stud 430 is welded to the top plate 310. The pressure plate 420 is placed on the upper surface of the head end of the hexagonal stud 430.

[0023] It should be noted that the photovoltaic module 400 is installed inside the mechanism box 300, and the two photovoltaic panels 410 are connected in parallel. The photovoltaic panels 410 can charge the charging controller and the battery.

[0024] It should be noted that the upper end of the inner surface of the fixed frame 412 is provided with an inwardly extending first protrusion, and the lower end of the inner surface of the fixed frame 412 is provided with an inwardly extending second protrusion. The upper surface of the glass plate 411 abuts against the first protrusion, and the lower surface of the glass plate 411 abuts against the second protrusion, thereby fixing the glass plate 411 by the fixed frame 412 and preventing the glass plate 411 from falling off the fixed frame 412.

[0025] It should be noted that the photovoltaic panel 410 is composed of a glass plate 411 and a fixed frame 412. The top plate 310 of the mechanism box 300 is welded together with the hexagonal stud 430. After the glass plate 411 is placed on the fixed frame 412, the fixed frame 412 and the glass plate 411 are bonded together with silicone sealant. The assembly gap between the fixed frame 412 and the top plate 310 of the mechanism box 300 is also filled with silicone sealant.

[0026] In existing technologies, pole-mounted switches using photovoltaic (PV) panels for auxiliary power supply are typically arranged separately from the PV panels. Installing PV panels requires additional mounting space on the utility pole for brackets to support and secure them. However, the pole already has pole-mounted switches, surge arresters, disconnectors, and distribution terminals installed, making it difficult to find suitable and safe locations for PV panel installation and easily leading to equipment congestion on the pole. Furthermore, the large size and windward area of ​​the independent brackets alter the overall mechanical structure of the utility pole, increasing the stress on the pole during severe weather and increasing wind load risk, threatening the stability of the PV panels, brackets, and the pole itself. Secondly, the positioning, bracket installation, and wiring of the PV panels increase the number of times and time spent manually climbing the pole, making the construction process more complex and resulting in higher labor and machinery costs. In addition, the DC power generated by the photovoltaic panels needs to be connected to the pole-mounted switch box through a long cable. The cable is exposed to the outdoor environment, and the longer the cable, the higher the line loss, the more fault points, the more difficult the lightning protection, and the exposed terminals, which means that the maintenance frequency of the photovoltaic panels is high.

[0027] It should be noted that, through this invention, the pressure plate 420 applies upward pressure to the fixed frame, causing the fixed frame 412 to be pressed into the mounting through hole of the mechanism box 300. The fixed frame 412 is used to fix the glass plate 411, thereby realizing the integrated integration of the photovoltaic panel 410 and the mechanism box 300, and the integrated integration of the pole-mounted switch 100 and the photovoltaic panel 410; that is, there is no need to set up additional brackets on the utility pole to support and fix the photovoltaic panel 410, which does not have an excessive impact on the stress structure of the utility pole and reduces the wind load risk of the utility pole; and, when installing the pole-mounted switch 100 The installation of the photovoltaic panel 410 is completed when it reaches the utility pole. Due to the simple structure of this application, the installation time of the photovoltaic panel 410 and the pole-mounted switch 100 can be further reduced, the number of times and time of manual pole climbing can be reduced, the construction procedure can be simplified, and labor and machinery costs can be reduced. At the same time, since the photovoltaic panel 410 is directly integrated into the inside of the pole-mounted switch 100, that is, the power supply cable of the photovoltaic panel 410 to the pole-mounted switch 100 is located inside the housing of the pole-mounted switch 100, the cable is not affected by the outdoor environment, further reducing the maintenance frequency of the photovoltaic panel 410.

[0028] Additionally, in one embodiment, reference is made to Figure 1 and Figure 2 The mechanism box 300 is equipped with three permanent magnet mechanisms 320. The epoxy pole post 200 includes an insulating pull rod 210. The upper end of the insulating pull rod 210 is located inside the epoxy pole post 200, and the lower end of the insulating pull rod 210 is located at one end of the permanent magnet mechanism 320. The other end of the permanent magnet mechanism 320 is fixed to the main shaft inside the mechanism box 300.

[0029] It should be noted that since the photovoltaic panel 410 is integrated inside the mechanism box 300, the internal space of the mechanism box 300 is reduced. That is, the space for the conventional spring-loaded mechanism in the mechanism box 300 is limited. Therefore, the spring-loaded mechanism is replaced with a lightweight, low-power permanent magnet mechanism 320, and the closing and opening of the pole-mounted switch 100 is realized through the permanent magnet mechanism 320.

[0030] Additionally, in one embodiment, reference is made to Figure 2 The lower end of the outer surface of the fixed frame 412 is provided with an outwardly extending boss. The height of the outer surface of the fixed frame 412 without the boss is equal to the thickness of the top plate 310. The upper surface of the boss abuts against the lower surface of the top plate 310.

[0031] It should be noted that the lower end of the outer surface of the fixed frame 412 is provided with an outwardly extending boss, so that the upper surface of the boss abuts against the lower surface of the top plate 310. The height of the outer surface of the fixed frame 412 without the boss is equal to the thickness of the top plate 310. This facilitates the positioning of the fixed frame 412 in the mounting through hole and makes the upper surface of the fixed frame 412 flush with the upper surface of the top plate 310, thereby realizing the rapid installation of the photovoltaic panel 410 and the top plate 310.

[0032] It should be noted that the pressure plate 420 presses the fixed frame 412 onto the top plate 310 of the mechanism box 300 through the support member, applying upward pressure to the photovoltaic panel 410, so that the photovoltaic panel 410 and the top plate 310 are relatively stationary. Also, since the fixed frame 412 is provided with a boss, the pressure applied to the photovoltaic panel 410 by the pressure plate 420 will not make the height of the upper surface of the photovoltaic panel 410 higher than the height of the top plate 310.

[0033] It should be noted that by setting the boss, the photovoltaic panel 410 is made to be flush with the height of the top plate 310. In the outdoor environment, this can prevent the photovoltaic panel 410 from being the first to be impacted or worn by external forces, and prevent dust from accumulating on the glass plate 411, which would reduce the utilization rate of solar energy by the photovoltaic panel 410.

[0034] Additionally, in one embodiment, reference is made to Figure 2 A sealing gasket 413 is provided between the fixed frame 412 and the top plate 310. The upper surface of the sealing gasket 413 abuts against the top plate 310, and the lower surface of the sealing gasket 413 abuts against the upper surface of the boss.

[0035] It should be noted that during installation, after fixing the support to the top plate 310 of the mechanism box 300, the sealing gasket 413 is placed at a predetermined position on the lower surface of the top plate 310. After placing the sealing gasket 413, the protrusion of the fixing frame 412 is aligned with the sealing gasket 413 to prevent damage to the fixing frame 412 and the top plate 310 when pressure is applied to the photovoltaic panel 410 by the pressure plate 420.

[0036] Additionally, in one embodiment, reference is made to Figure 1 and Figure 2 It also includes: a first nut 440 and a washer, a second screw is provided on the lower surface of the pressure plate 420, the second screw passes through the first nut 440, the upper surface of the washer abuts against the pressure plate 420, and the lower surface of the washer abuts against the first nut 440.

[0037] It should be noted that the pressure plate 420 presses the fixing frame 412 of the photovoltaic panel 410 and the sealing gasket 413 onto the top plate 310 of the mechanism box 300 through the first nut 440 and the washer. The pressing size ensures that the deformation of the sealing gasket 413 is not less than 20% to ensure sufficient sealing.

[0038] It should be noted that the two photovoltaic panels 410 are integrated on the top plate 310 of the mechanism box 300 through a sealed fixing structure. The mechanism box 300 and all the epoxy poles 200 together form a pole-mounted switch 100. During the complete installation of the photovoltaic module 400, the glass plate 411 is placed inside the fixed frame 412, and the glass plate 411 and the fixed frame 412 are pre-bonded with silicone sealant to form a waterproof boundary. The stud end of the hexagonal stud 430 is welded to the lower surface of the top plate 310 of the mechanism box 300 to form a support point, and the sealing gasket 413 is placed in the predetermined position of the top plate 310. The fixed frame 412 of the photovoltaic module 410 is aligned and placed on the sealing gasket 413, and the fixed frame 412 is pressed tightly against the fixed frame 412 using the pressure plate 420 and nut assembly. During the pressing process, the torque of the nut is controlled to ensure that the deformation of the sealing gasket 413 is not less than 20% to achieve the IP65 protection level. Silicone sealant is filled in the assembly gap between the fixed frame 412 and the top plate 310 of the mechanism box 300 to form a double seal. After the installation of the photovoltaic module 400 is completed, an airtightness test is performed on the mechanism box 300 to verify the protection level. The organization in this application has achieved high integration through standardized processes, avoiding the complex wiring of discrete structures.

[0039] In addition, embodiments of the present invention provide a method based on a pole-mounted switch including a photovoltaic panel, applicable to... Figures 1 to 3 The illustrated embodiment is based on a pole-mounted switch including a photovoltaic panel, with reference to... Figure 4 The method includes, but is not limited to, the following steps: S10: Start the two photovoltaic panels, determine the sampling period duration, and at each sampling period interval, collect the output voltage and output current of the two photovoltaic panels; S20: Based on any photovoltaic panel, determine the current-voltage characteristic curve of the photovoltaic panel by collecting all output voltages and output currents over multiple acquisition cycles, determine the maximum power of the photovoltaic panel based on the current-voltage characteristic curve, and collect the real-time voltage and real-time current of the photovoltaic panel in real time to obtain the real-time power of the photovoltaic panel. S30: The photovoltaic panel with the highest real-time power is identified as the main board, and the other photovoltaic panel is identified as the slave board. When the difference between the real-time power of the main board and the maximum power of the main board is greater than or equal to the first power difference threshold, the duty cycle of the main board is adjusted until the difference between the real-time power of the main board and the maximum power of the main board is less than the first power difference threshold. S40: When the difference between the real-time power of the motherboard and the real-time power of the slave board is greater than or equal to the second power difference threshold, adjust the duty cycle of the slave board until the difference between the real-time power of the motherboard and the real-time power of the slave board is less than the second power difference threshold.

[0040] It should be noted that this invention employs a dual-photovoltaic-panel collaborative control method. For the configuration of two photovoltaic panels, a parallel operation and fault switching process is designed to improve energy harvesting efficiency and reliability. The two photovoltaic panels are connected in parallel to the charging controller inside the mechanism box. The output current and output voltage of each photovoltaic panel are monitored in real time, and the operating point of the photovoltaic panel is dynamically adjusted through a maximum power point tracking (MPPT) algorithm to ensure power balance between the two photovoltaic panels and avoid power efficiency loss due to shading or dirt.

[0041] In another embodiment, in step S10, the output voltage and output current of the two photovoltaic panels are collected at intervals of the acquisition cycle duration, which may include, but is not limited to, the following steps: S111: At each sampling period, the output voltage and output current of the two photovoltaic panels are acquired. Based on any one photovoltaic panel, the output voltage and output current are multiplied to obtain the real-time power of the photovoltaic panel. S112, when the output power of one of the photovoltaic panels is less than the preset power threshold, the photovoltaic panel with the output power less than the preset power threshold is isolated, and the other photovoltaic panel supplies power to the charging controller separately, and the pole switch sends an alarm signal.

[0042] It should be noted that this invention monitors the status of the photovoltaic panels. If one of the photovoltaic panels experiences a sudden drop in output power, indicating a photovoltaic panel failure, the faulty panel is automatically isolated, and the power supply to the charging controller and battery is switched to another photovoltaic panel, simultaneously triggering an alarm signal. Through the fault detection and automatic switching method of this application, redundancy backup is achieved, improving the fault tolerance of the pole-mounted switch.

[0043] In another embodiment, after activating the two photovoltaic panels in step S10, the following steps are included, but are not limited to: S121 obtains the outdoor ambient light intensity through two photovoltaic panels. When the light intensity is greater than or equal to the preset light threshold, the two photovoltaic panels charge the battery through the charging controller. The two photovoltaic panels directly supply power to the electrical system of the pole-mounted switch. The charging controller uses a three-stage charging method to charge the battery. S122, or, when the light intensity is less than the preset light threshold, control the two photovoltaic panels to stop supplying power to the charging controller and the battery, control the battery to supply power to the electrical system, monitor the battery power in real time, and when the battery power is less than the preset power threshold, the battery only supplies power to the permanent magnet mechanism.

[0044] It should be noted that in normal mode, when the light intensity is greater than or equal to the preset light threshold, i.e., when the light is sufficient, both photovoltaic panels simultaneously charge the battery of the pole-mounted switch and directly power the electrical system of the pole-mounted switch. The charging controller adopts a three-stage charging method, namely constant current, constant voltage, and float charging, to extend the battery life.

[0045] It should be noted that in backup mode, when the light intensity is less than the preset light threshold (i.e., insufficient light), the system automatically switches to battery power to supply the pole-mounted switch. The battery level is monitored in real time; if the level is less than the preset threshold, non-critical load power is reduced to prioritize switch operation, i.e., power is supplied to the permanent magnet mechanism first. Alternatively, the system also switches to backup mode when the motherboard malfunctions.

[0046] It should be noted that in recovery mode, when the light intensity is greater than or equal to the preset light threshold again, the charging process will automatically restart and energy data will be recorded for maintenance analysis.

[0047] It should be noted that this invention achieves a highly integrated structure between the photovoltaic panel and the pole-mounted switch mechanism box, resulting in a compact design that significantly saves pole space. It eliminates the need for bulky, separate supports and complex pole wiring, greatly improving the structural stability and space utilization of the pole. The design is aesthetically pleasing and significantly enhances the photovoltaic panel's wind resistance. The IP65 protection rating ensures the core electrical connections are internally sealed, fundamentally avoiding the technical pain points of exposed cables being prone to corrosion and having a high failure rate, achieving extremely high environmental tolerance and "maintenance-free" operation. Simultaneously, integrated hoisting greatly simplifies the installation process, improving efficiency and safety, and achieving a comprehensive improvement in reliability, economy, and aesthetics throughout the entire lifecycle of the pole-mounted switch.
