[0040] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0041] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] like Figures 1 to 3 As shown, a series high-voltage ring main unit comprises: a cabinet body 100 and a cabinet door 101. Specifically, the cabinet body 100 is provided with a space for accommodating electrical components; one side of the cabinet door 101 is rotatably connected to the cabinet body 100, and the cabinet door 101 is used to close the cabinet body 100 space. The cabinet body 100 is installed with components required for the ring main unit.

[0043] The cabinet 100 is provided with a vent, and a frame 300 is provided in the vent. The frame 300 is detachably connected with a mounting frame 200, and a dust removal device is provided on the mounting frame 200. The dust removal device is used to absorb dust in the airflow passing through the mounting frame 200; the frame 300 is provided with a first cavity, and a first coil 301 is provided in the first cavity; the mounting frame 200 is provided with a second cavity, and a second coil 207 is provided in the second cavity; a first cover plate 302 is provided on the side wall of the first cavity, and a second cover plate 206 is provided on the side wall of the second cavity. 302 is snapped into the first cavity to close the first cavity, and the second cover plate 206 is snapped into the second cavity to close the second cavity. The first cover plate 302 and the second cover plate 206 fix the first coil 301 and the second coil 207 in the first cavity and the second cavity, and at the same time provide convenience for the disassembly of the first coil 301 and the second coil 207; wherein, when the mounting frame 200 is in the frame body 300, the first coil 301 generates low-voltage direct current on the second coil 207 to supply the dust removal device to generate an ionization zone in the mounting frame 200.

[0044] When maintaining the first coil 301, after opening the cabinet door 101, the first cover plate 302 is exposed, and the first cover plate 302 is removed from the first cavity, and the first coil 301 can be directly taken out from the first cavity; when maintaining the second coil 207, the installation frame is removed from the frame body, the second cover plate 206 is exposed outside, and the second cover plate 206 is removed from the second cavity, and the second coil 207 can be directly taken out from the second cavity.

[0045] like Fig.13 As shown, air enters the cabinet 100 from the vents to dissipate heat for the cables and components in the cabinet 100. The current on the cables connected to the cabinet 100 is directly connected to the first coil 301 through the wire, providing current for the first coil 301. Under the action of electromagnetic mutual induction, current is generated on the second coil 207. The number of turns on the second coil 207 is less than the number of turns on the first coil 301, so low-voltage current is generated on the second coil 207. A diode is connected to the output wire of the second coil 207. The diode limits the current direction on the second coil 207, so that unidirectional direct current is generated on the second coil 207, thereby achieving the requirement that the second coil 207 generates low-voltage direct current. The second coil 207 supplies power to the dust removal device, and an ionization zone is generated on the mounting frame 200. The air is ionized after passing through the ionization zone, and dust in the air is removed, so as to prevent dust from entering the cabinet 100 and affecting the normal operation of electrical components.

[0046] Use low-voltage direct current to power the dust removal device to avoid high-voltage discharge when the ring network cabinet is in use and cause harm to nearby personnel, thereby increasing the safety of the ring network cabinet.

[0047] Specifically, a first mounting groove is provided on the frame body 300, and the mounting frame 200 is embedded in the first mounting groove. The mounting frame 200 is a rectangular frame structure. The shape of the first mounting groove corresponds to the shape of the mounting frame 200. A through groove is provided at the bottom of the first mounting groove, and the through groove corresponds to the frame of the mounting frame 200. The cross-section of the first mounting groove corresponds to the vent. When the mounting frame 200 is installed in the first mounting groove, the air flowing through the vent passes through the dust removal device to prevent dust from entering the cabinet body 100 and affecting the electrical components.

[0048] Specifically, the first cavity is arranged on the periphery of the first mounting groove, that is, the first cavity is wrapped around the outer circle of the first mounting groove. When the mounting frame 200 is in the first mounting groove, the first coil 301 and the second coil 207 overlap with each other on the orthographic projection plane; the so-called orthographic projection plane is a projection plane formed by projecting vertically downward from the top of the cabinet 100; the first coil 301 and the second coil 207 are both rectangular frame structures. When the mounting frame 200 is in the first mounting groove, the first coil 301 is wrapped around the outer circle of the second coil 207, so that the overlap of the magnetic flux lines of the first coil 301 and the second coil 207 is maximized, the power loss is reduced, and a voltage is generated on the second coil 207 to form an ionization zone.

[0049] The dust removal device includes: an ionization net, which is arranged on a mounting frame 200; a collector, which is arranged on one side of the ionization net; specifically, the collector is arranged on a side of the ionization net close to the interior of the cabinet 100, so that the air passing through the ionization net passes through the collector, and an ionization zone is generated on the ionization net, so that the air passing through the ionization net passes through the collector, and dust in the air is collected to prevent dust from entering the cabinet 100.

[0050] The ionizing network is composed of two second mounting blocks 221, a plurality of conductive wires 103 and a plurality of first guide plates 105. The conductive wires 103 and the first guide plates 105 are arranged between the two second mounting blocks 221, and the two ends of the conductive wires 103 and the first guide plates 105 are respectively fixedly connected to the two second mounting blocks 221; a second mounting groove is arranged on the inner wall of the frame structure on the mounting frame 200, and the second mounting block 221 can be installed in the second mounting groove; a first sliding block 215 is arranged on the second mounting block 221, and a first sliding groove is arranged on the inner wall of the second mounting groove. When the second mounting block 221 is installed in the second mounting groove, the first sliding block 215 is embedded in the first sliding groove, and the ionizing network is positioned by using the cooperation of the first sliding block 215 and the first sliding groove, so as to reduce the squeezing of the second mounting block 221 on the first guide plate 105.

[0051] The first guide plate 105 is connected to a negative voltage, and the conductive wire 103 is connected to a positive voltage. The first guide plate 105 and the conductive wire 103 are spaced apart, specifically, a conductive wire 103 is arranged between two first guide plates 105, and there is a gap between every two first guide plates 105, through which air passes; after the second coil 207 generates a voltage under the action of the first coil 301, the negative voltage passes through the first guide plate 105, and the positive voltage passes through the conductive wire 103, and the current passing through the conductive wire 103 is discharged between the two first guide plates 105, thereby forming an ionization zone between the two first guide plates 105, and the air is ionized after passing between the two first guide plates 105, and the dust in the air is positively charged, so that the dust is collected on the collector after passing through the collector.

[0052] Preferably, a first terminal 204 is provided on the second mounting block 221, a first connecting groove is provided on the inner wall of the first slide groove, a terminal is provided on the inner wall of the first connecting groove, the terminal is connected to the output wire of the second coil 207, all the first guide plates 105 are electrically connected to the first connecting post on the left second mounting block 221, all the conductive wires 103 are electrically connected to the first connecting post on the right second mounting block 221, the output wire connected to the first terminal 204 on the left second mounting block 221 is the negative output wire of the second coil 207, the output wire connected to the first terminal 204 on the right second mounting block 221 is the positive output wire of the second coil 207, the first terminal 204 is used to connect all the positive and negative wirings in series, the electrical properties of all the first guide plates 105 and all the conductive wires 103 are ensured, a stable ionization zone is generated on the ionization net to ensure that all the passing air is ionized.

[0053] like Fig.12 As shown, the collector is composed of two third mounting blocks 222 and a plurality of second guide plates 104. The second guide plates 104 are arranged between the two third mounting blocks 222. There is a gap between each two second guide plates 104 for air to pass through. The electrical properties of two adjacent second guide plates 104 are opposite, that is, the second guide plates 104 are energized in a positive-negative-positive-negative manner. The third mounting block 222 is provided with a second slider matched with the first slide groove. The third mounting block 222 is provided with a second terminal 205. All the second guide plates 104 showing negative poles are connected to the left and right terminals. The second terminal 205 on the third mounting block 222 on the side is electrically connected, and all the second guide plates 104 showing positive poles are in phase with the second terminal 205 on the third mounting block 222 on the right side; after the third mounting block 222 is installed in the second mounting groove, the second terminal 205 is inserted into the first connection groove, the second terminal 205 contacts the terminal, the negative electrode of the second coil 207 is connected to the left terminal, and the positive electrode of the second coil 207 is connected to the right terminal, so that the electrodes of the second guide plate 104 on the collector are spaced apart.

[0054] When installing the dust removal device, first install the third installation block 222 into the second installation groove to complete the installation of the collector, and then install the second installation block 221 into the second installation groove to complete the installation of the ionization network. The first terminal 204 and the second terminal 205 are both in contact with the terminal. After the second coil 207 generates voltage, the current is transmitted through the terminal and the terminal, and an ionization zone is generated on the ionization network. The air is ionized when passing through the ionization zone, and the dust in the air is positively charged. When the air drives the dust through the collector, the dust with positive charge is adsorbed onto the second guide plate 104 connected to the negative voltage, and the clean air passes through the gap between the two second guide plates 104, thereby purifying the air, reducing the dust entering the cabinet 100, and protecting the electrical components in the cabinet 100.
