Description

Technical Field

[0001] This utility model relates to the field of ring network box technology, and in particular to a ring network box with dustproof function. Background Technology

[0002] Ring mains boxes, also known as outdoor power switch boxes, are typically installed outdoors along roadsides, in residential areas, and even in harsher environments such as high mountains or deserts. These environments all share a common characteristic: high levels of dust. Dust is easily carried by airflow, and when air convection occurs within the ring mains box, dust enters. The ring mains box houses high-voltage equipment, primarily air-insulated, with the high-voltage electric field isolated by insulators or cable terminations. Dust entering the ring mains box is ionized under the influence of the high-voltage electric field and then adsorbed onto the surface of the insulation components. As the equipment is used over time, the accumulated dust further reduces insulation, potentially leading to flashover, creepage, or burnout accidents in the high-voltage equipment. Utility Model Content

[0023] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] As described in the background section, air convection occurs within the ring main unit. The high-voltage equipment inside the ring main unit generates a significant amount of heat during operation, creating a substantial temperature difference between the inside and outside of the unit, which facilitates air convection. Simultaneously, ambient air also needs to enter the ring main unit to dissipate heat from the high-voltage equipment. Therefore, without dust prevention measures, dust from the air will inevitably enter the ring main unit and, influenced by the electric field of the high-voltage equipment, accumulate on the surface of the equipment and its insulating components.

[0028] Even if some ring main units do not require air convection for heat dissipation, it is still difficult to further improve the sealing between the door panel and the door frame. Generally, the sealing between the door panel and the door frame is achieved by sealing strips. These sealing strips are prone to aging and failure in harsh outdoor environments, which can also cause dust to enter the ring main unit with the airflow.

[0029] Reference Figure 1 As shown, an embodiment of the present invention, a ring main unit with dustproof function, includes a housing 100, a door panel, and a dust removal device. It should be understood that, in Figure 1 and Figure 2 In the image, box 100 is not fully shown. Furthermore... Figure 1 and Figure 2 The door panel is not shown in the image.

[0030] The housing 100 has a door opening with a door frame 110 around it; a door panel is installed in the door opening, and when the door panel is in the closed position, the edge of the door panel extends into the door opening, and there is a gap between the edge of the door panel and the door frame 110; a dust removal device is installed between the edge of the door panel and the door frame 110 to fill the gap.

[0031] The ring main unit 100 has a door opening for maintenance or equipment installation. During normal operation, the door opening must be closed by a door panel. The door panel is hinged to the unit 100 on one side; rotating along the hinge axis moves the door panel to the open or closed position. When the door panel is closed, its frame extends into the door opening, effectively covering it. Ambient air enters the unit 100 through the gap between the door panel frame and the door frame 110. A dust removal device is installed between the door panel frame and the door frame 110 to fill the gap. Air entering the unit 100 must pass through this dust removal device, which traps and filters dust, minimizing the amount of dust and reducing the risk of electrical insulation damage due to dust accumulation on the insulating components of high-voltage equipment.

[0032] It is important to understand that dust removal devices can have various structures and implementation methods to trap dust in the air. For example, a dust removal device can be a filter or a bag filter, but this structure is relatively complex to install between the door panel frame and the door frame 110. A simpler structure is a dust removal device that includes an electrostatic generator 210.

[0033] An electrostatic generator 210 is positioned between the door panel frame and the door frame 110. The electric field generated by the electrostatic generator 210 ionizes dust particles in the air. After being charged, the dust particles separate from the air under the influence of the electric field and gradually approach the positive plate of the electrostatic generator 210, eventually being adsorbed onto it. After passing through the electrostatic generator 210, the amount of dust carried by the air is greatly reduced, significantly reducing the amount of dust entering the housing 100 with the airflow.

[0034] Reference Figure 2 As shown, it can be understood that the static electricity generating component 210 is disposed on the frame of the door panel, and there is a gap between the static electricity generating component 210 and the door frame 110.

[0035] The electrostatic generator 210 is mounted on the door frame and can move as the door is opened and closed. Opening the door facilitates cleaning of accumulated dust on the electrostatic generator 210, restoring its dust-removing effect. A gap is maintained between the electrostatic generator 210 and the door frame 110. This gap serves two purposes: firstly, to prevent interference between the electrostatic generator 210 and the door frame 110 when the door is opened; and secondly, to provide an airflow channel, allowing air to pass through the electrostatic generator 210 before entering the housing 100, thus trapping dust in the air.

[0036] It is understood that the electrostatic generator assembly 210 includes an electrode plate 211 and an insulating member 212. The electrode plate 211 is fixed to the frame of the door panel and can move with the door panel. The electrode plate 211 is provided with an insulating member 212. When the door panel is in the closed position, the insulating member 212 abuts against the door frame 110 to keep the electrode plate 211 and the door frame 110 in an open circuit state.

[0037] Electrode plate 211 is preferably connected to the positive terminal of the power supply as a positive electrode plate. An insulating component 212 is disposed on electrode plate 211 to isolate electrode plate 211 from door frame 110, preventing electrode plate 211 from contacting and conducting with door frame 110, which would cause door frame 110 to also become charged. Since electrode plate 211 is preferably a positive electrode plate, dust particles in the air are ionized by the electric field, carrying electrons and becoming negatively charged. When dust particles pass through the positive electrode plate 211, the negatively charged dust particles are attracted by electrode plate 211 and ultimately adsorbed onto it.

[0038] It should be understood that the insulating component 212 of the static electricity generating component 210 is not the same component as the insulating component of the high-voltage equipment inside the housing 100, but both serve the purpose of insulation.

[0039] It is understood that the insulating component 212 includes multiple insulating terminals, which are evenly distributed along the edge of the door panel on the electrode plate 211.

[0040] The insulating terminals are evenly distributed on the electrode plate 211, which plays a role in evenly distributing the force on the electrode plate 211 and preventing the electrode plate 211 from tilting up under stress in some cases and interfering with the door frame 110.

[0041] It is understandable that the electrode plate 211 is provided with a dust collection trough, which has a accommodating space and the opening of the dust collection trough faces the door frame 110.

[0042] When the electrode plate 211 is preferably used as a positive electrode plate, dust carrying negative charges gathers towards the electrode plate 211 and is adsorbed. A dust collection groove is provided on the electrode plate 211 so that the dust can fall into the dust collection groove by itself and also facilitates the subsequent cleaning of the electrostatic generating component 210.

[0043] It is important to understand that the dust collection trough should preferably be made of plastic parts with good insulation properties.

[0044] It is understood that the electrode plate 211 includes at least four plate assemblies, and the multiple plate assemblies are distributed around the perimeter of the door panel. Each plate assembly includes a first plate 213 and a second plate 214. The first plate 213 and the second plate 214 intersect, so that the cross-section of the plate assembly is L-shaped. The dust collection groove is disposed at the intersection between the first plate 213 and the second plate 214. The first plate 213 is fixed to the door panel frame, and the second plate 214 is located inside the housing 100.

[0045] After the first plate 213 is fixed to the frame of the door panel, the second plate 214 can be positioned on the outside or inside of the housing 100 due to the structural constraints of the first plate 213 and the second plate 214. Preferably, the second plate 214 is adjusted to be positioned on the inside of the housing 100, and the door panel is correspondingly adjusted to open towards the inside of the housing 100. In the above structure, when the door panel is in the closed position, the second plate 214 can be parallel to the surface of the door panel. That is, when the air from the external environment enters the housing 100 through the gap between the door panel and the door frame 110, it will be blocked by the second plate 214, changing the direction of airflow and reducing the airflow speed; this can further promote the adsorption of dust in the air by the electrode plate 211. The dust collection groove is preferably placed at the intersection of the first plate 213 and the second plate 214, which can achieve better dust collection effect and also facilitates adjusting the opening of the dust collection groove towards the gap between the frame of the door panel and the door frame 110.

[0046] Understandably, it also includes a power generation device, a power control module, and a storage battery. The power generation device is electrically connected to the power control module, the power control module is electrically connected to the storage battery, and the storage battery is electrically connected to the static electricity generation component 210.

[0047] By combining a generator with a battery to provide energy to the electrostatic generator 210, energy self-sufficiency can be achieved. Furthermore, an independent power supply circuit is provided for the electrostatic generator 210, eliminating the need to modify the high-voltage equipment within the enclosure 100 and ensuring stable operation of the high-voltage equipment. The power control module controls the charging current of the battery. However, the power control module is not limited to controlling the charging current; it can also control and adjust other battery parameters as needed, ensuring the battery operates under suitable conditions.

[0048] Understandably, the power generation device includes multiple photovoltaic panels, which are installed on the top of the housing 100.

[0049] In some embodiments, the power generation device may be a photovoltaic panel that converts solar energy into electrical energy, stores it in a battery, and provides energy for the static electricity generation component 210.

[0050] Understandably, the power generation unit includes a tower and a wind turbine. The tower is vertically supported, and the wind turbine is located at the top of the tower and is electrically connected to a battery.

[0051] In other embodiments, a wind turbine is used to convert wind energy into electrical energy, which is stored in a battery and provides power to the static electricity generation component 210. Both wind and solar energy are clean energy sources.

[0052] It should be understood that in some embodiments, photovoltaic panels and wind turbines can be installed simultaneously, complementing each other. For example, in cases of insufficient sunlight, the wind turbine primarily replenishes the battery's power; in cases of insufficient wind, solar energy primarily replenishes the battery's power. If both sunlight and wind are insufficient, the battery itself can also store energy to power the electrostatic generator 210. Of course, when there is sufficient wind and sunlight, both the photovoltaic panels and the wind turbine can simultaneously replenish the battery's power, reducing the time consumed in replenishing power.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
