DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-2 As shown, this embodiment provides a low-voltage distribution cabinet that is easy to manage intelligently, including a distribution cabinet body 1, wherein the distribution cabinet body 1 has an electrical component cabinet box 101 and an intelligent management cabinet box 102, the electrical component cabinet box 101 is used to install the distribution switches and wiring of the power system, and the intelligent management cabinet box 102 is used to install GPRS data transmission equipment and control equipment of the power system. The electrical component cabinet 101 and the intelligent management cabinet 102 are separated by a middle partition, and a heat dissipation device is provided inside the distribution cabinet body 1. The heat dissipation device includes two bellows 2 fixed on both sides of the distribution cabinet body 1, and the two bellows 2 are respectively opposite to the sides of the electrical component cabinet 101 and the intelligent management cabinet 102. Heat dissipation ports 201 are arranged at intervals along the vertical direction on the surface of the bellows 2, and a heat dissipation fan 202 is fixedly installed on the inner wall of the heat dissipation port 201. The heat dissipation device also includes a coil 3 arranged directly opposite to the outer port of the heat dissipation fan 202. Side partitions are provided on the outer sides of the electrical component cabinet 101 and the intelligent management cabinet 102, and ventilation windows 105 are provided on the surface of the side partitions opposite to the position of the heat dissipation fan 202. The airflow blown out by the heat dissipation fan 202 can enter the electrical component cabinet 101 and the intelligent management cabinet 102 through the coil 3 and the ventilation window 105 in turn to dissipate heat from the electrical equipment.

[0028] Among them, a configuration box 103 is provided inside the power distribution cabinet body 1, and a dust removal water tank 4 and a cooling water tank 5 are fixed inside the configuration box 103. An air intake channel 6 is connected to one side of the dust removal water tank 4, and the outer port of the air intake channel 6 is connected to the outside of the power distribution cabinet body 1. An air suction fan 7 is fixedly installed on the inner wall of the outer port of the air intake channel 6, and a dust filter is provided at the outer port of the air suction fan 7. The inner end of the air intake channel 6 extends toward the bottom of the inner cavity of the dust removal water tank 4, and aeration holes 601 are evenly provided on the side surfaces around the inner port of the air intake channel 6. An exhaust port 8 is provided on the upper part of the dust removal water tank 4, and the exhaust port 8 is respectively connected to the two bellows through a ventilation pipe 9. 2 is connected, a certain amount of water is contained in the dust removal water tank 4, and the inner end of the air inlet channel 6 extends below the water surface. When the electrical equipment is cooled, the suction fan 7 guides the airflow from the air inlet channel 6 into the dust removal water tank 4. The airflow contacts the water, and the small particles of solid dust in the airflow will remain in the water of the dust removal water tank 4. The airflow enters the cavity above the water surface of the dust removal water tank 4, and then enters the two bellows 2 through the exhaust port 8 and the ventilation pipe 9. Therefore, the heat dissipation airflow blown into the inner cavity of the distribution cabinet body 1 by the heat dissipation fan 202 has been effectively dust-removed, and will not pollute the environment and electrical equipment in the cabinet, and the protection effect is better.

[0029] Furthermore, an A water inlet pipe 14 is provided at the upper end of the dust removal water tank 4, an A electromagnetic valve 15 is provided on the A water inlet pipe 14, the outer end of the A water inlet pipe 14 is connected to the city water supply pipe 18, a water outlet pipe 16 is provided at the lower end of the dust removal water tank 4, a B electromagnetic valve 17 is provided on the water outlet pipe 16, a liquid level sensor probe 19 is fixed to the inner wall of the dust removal water tank 4, a dust filter net 24 is fixed to the inner side wall of the dust removal water tank 4, the dust filter net 24 is located above the port in the air inlet channel 6, and the dust filter net 24 can further play a role in intercepting dust particles, and a PLC controller 20 is fixedly installed inside the intelligent management cabinet 102, and the PLC controller 20 is respectively connected to the liquid level sensor probe 19, the A electromagnetic valve 15, and the B electromagnetic valve 17, and the liquid level sensor probe 19 is used to monitor the liquid level height in the dust removal water tank 4, so as to prevent the water surface from submerging the exhaust port 8. The built-in program of the PLC controller 20 is set to regularly open or close the A and B electromagnetic valves, so as to regularly replace the dust removal water to ensure the dust removal effect. The specific principle is: first, the PLC controller 20 regularly controls the B electromagnetic valve 17 to open, so that the dust-containing sewage is discharged through the outlet pipe 16, and the outlet pipe 16 is connected to the sewer. After draining for a period of time, the B electromagnetic valve 17 is closed, and then the A electromagnetic valve 15 is opened to allow the municipal tap water to enter the dust removal water tank 4 through the A inlet pipe 14. When the liquid level sensor probe 19 detects that the water level reaches the preset height, the liquid level sensor probe 19 sends a signal to the PLC controller 20, and the PLC controller 20 closes and opens the A electromagnetic valve 15 until the next water change cycle, and then repeats the above steps.

[0030] Among them, the cooling water tank 5 is connected with the coil 3 through a water pipe and a water pump 10 to form a circulation pipeline 11. A B water inlet pipe 21 is provided at the upper end of the cooling water tank 5. A manual valve 22 is provided on the B water inlet pipe 21. The B water inlet pipe 21 is connected to the city water supply pipe 18. By opening the manual valve 22, the cooling water tank 5 can be filled with tap water. A semiconductor radiator 12 is fixed to the outer wall of the cooling water tank 5. Heat dissipation fins are fixed to the outer side of the semiconductor radiator 12. The semiconductor radiator 12 and the heat dissipation fins can be communicated with the outside of the distribution cabinet body 1 when installed. An opening suitable for the size of the semiconductor radiator 12 is provided on the side of the distribution cabinet body 1. When dissipating heat to the electrical equipment, the semiconductor radiator 12 is opened to transfer the heat of the water in the cooling water tank 5 to the outside. The water in the cooling water tank 5 is driven by the water pump 10 to circulate in the circulation pipeline 11. When the water flows through the coil 3, it will absorb the heat in the surrounding air, so that the heat dissipation airflow blown into the inner cavity of the distribution cabinet body 1 by the cooling fan 202 has a better heat dissipation effect.

[0031] Furthermore, an exhaust cavity 104 is provided on the upper part of the distribution cabinet body 1, and mesh exhaust windows 13 are provided on the upper parts of the electrical component cabinet box 101 and the intelligent management cabinet box 102. The electrical component cabinet box 101 and the intelligent management cabinet box 102 are communicated with the exhaust cavity 104 through the mesh exhaust windows 13. Dust shields 23 are alternately provided between the upper and lower inner walls of the exhaust cavity 104. The gaps between the dust shields 23 form a maze-like exhaust channel. The two sides of the exhaust cavity 104 are communicated with the outside through filters. The maze-like exhaust channel formed by the gaps of the dust shields 23 can prevent external dust from entering the electrical cabinet body 1. The heat dissipation airflow blown into the inner cavity of the distribution cabinet body 1 by the heat dissipation fan 202 is finally discharged to the outside of the distribution cabinet body 1 through the mesh exhaust windows 13 and the exhaust cavity 104.

[0032] When the low-voltage distribution cabinet of the present invention is in use, in order to facilitate intelligent management and thus better protect the power system, an air switch can be installed in the intelligent management cabinet box 102 to control the intake fan 7, the cooling fan 202 of the heat dissipation device, the water pump 10 and the semiconductor radiator 12, so that the cooling fan 202 dissipates heat to the power system through the dust-removed air, and the cooling water in the coil can improve the heat dissipation efficiency and effect, thereby improving the protection of the low-voltage distribution cabinet during use.
