[0034] 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.

[0035] See also Figure 1-Figure 10 The present invention provides a power distribution cabinet for an electric power system, comprising a power distribution cabinet body 1.

[0036] Reference Figure 1-Figure 4 and Figure 7 As shown, the power distribution cabinet body 1 includes a cabinet body 11, an inner cavity 12, air holes 13 and a door panel 14. The cabinet body 11 is provided with an inner cavity 12, and air holes 13 are evenly provided inside the cabinet body 11 on both sides of the inner cavity 12. A door panel 14 is hinged on one side of the cabinet body 11, and a dustproof structure 2 is fixed on the outer wall of the cabinet body 11 outside the air holes 13. The dustproof structure 2 includes a mounting frame 21, a dustproof plate 22 and dustproof holes 23. The mounting frame 21 is evenly fixed on the outer wall of the cabinet body 11, and a dustproof plate 22 is provided on the inner side of the mounting frame 21. Dustproof holes 23 are evenly provided inside the dustproof holes 23. The mounting frame 21 is symmetrically distributed on both sides of the cabinet body 11, and the mounting frame 21 is symmetrically distributed on both sides of the dustproof plate 22. The dustproof plate 22 and the mounting frame 21 are slidably connected, and the dustproof holes 23 are evenly spaced inside the dustproof plate 22.

[0037] Align the bottom end of the dustproof plate 22 and the reserved groove on the inner side of the mounting frame 21, then press the bottom end of the dustproof plate 22 into the reserved groove on the inner side of the mounting frame 21, and continue pressing until the bottom end of the dustproof plate 22 and the inner wall of the bottom of the mounting frame 21 contact each other, and the dustproof plate 22 is installed. When the dustproof plate 22 needs to be taken out, hold the top of the dustproof plate 22 and pull it upward to take the dustproof plate 22 out. The dustproof hole 23 can isolate the floating dust in the air on one side of the dustproof plate 22 to prevent the floating dust from entering the inner cavity 12 through the air vent 13.

[0038] Reference Figure 2-Figure 9 As shown, the inner cavity 12 is evenly fixed with an inspection structure 3, and the inspection structure 3 includes a mounting plate 31, a mounting box 32, an inspection box 33, a circuit dust collecting plate 34, a circuit board 35, a connecting line 36, a terminal 37 and a protective door 38. The mounting plate 31 is evenly fixed on the inner wall of the cabinet 11 inside the inner cavity 12, and the top of the mounting plate 31 is slidably connected with the mounting box 32, and the interior of the mounting box 32 is provided with an inspection box 33, and the inner wall of one side of the inspection box 33 is fixed with a circuit dust collecting plate 34. 4. The circuit boards 35 are fixed on the inner wall of one side of the installation box 32. The terminals 37 are evenly fixed on the inner wall of the cabinet 11 on one side of the installation box 32. The inside of the terminals 37 is connected with a connecting wire 36 by interference fit. A protective door 38 is hinged on one side of the installation box 32. The installation boxes 32 are evenly spaced inside the inner cavity 12. Both sides of the inspection box 33 are slidably connected to the inner wall of the installation box 32. One end of the connecting wire 36 extends to the inside of the installation box 32 and is fixedly connected to the circuit board 35.

[0039] The installation box 32 is slid to the inner side of the inner cavity 12 until one end of the connecting wire 36 enters the interior of the terminal 37 to complete the power-on. When it is necessary to inspect the parts inside the maintenance box 33, the maintenance box 33 is pulled out from the interior of the installation box 32, and the parts inside the maintenance box 33 can be inspected. When the maintenance box 33 is pulled out, since the wires on one side of the circuit dust collecting plate 34 are reserved with sufficient length and are spring-shaped, the wires will be stretched as the maintenance box 33 moves, but will not affect the power-on. In this way, it can be ensured that the parts inside the maintenance box 33 will not be powered off during maintenance. When the power needs to be turned off for maintenance, the turning handle 46 is used to unlock the installation box 32 and the cabinet 11, and then the installation box 32 is pulled outward as a whole, so that the connecting wire 36 is pulled out from the interior of the terminal 37 to turn off the power.

[0040] Reference Figure 2-Figure 4 and Figure 8-Figure 10As shown, a locking structure 4 is provided on one side of the interior of the mounting plate 31, and the locking structure 4 includes a limit seat 41, a socket 42, a rotating shaft 43, a clamping seat 44, a clamping plate 45 and a rotating handle 46. The rotating shaft 43 passes through one side of the bottom of the mounting plate 31, and the interior of the mounting plate 31 is fixed with the limit seat 41 at one end of the rotating shaft 43, and the interior of the limit seat 41 is provided with a socket 42. One end of the rotating shaft 43 extends to the outside of the mounting plate 31 and is fixed with the clamping seat 44. The clamping plate 45 is evenly fixed on the inner wall of the cabinet 11 near the clamping seat 44. The outer diameter of the socket 42 is smaller than the inner diameter of the limit seat 41. One end of the rotating shaft 43 extends to the interior of the limit seat 41 and is fixedly connected to one end of the socket 42. The rotating shaft 43 and the limit seat 41 are rotatably connected, and the clamping seat 44 and the clamping plate 45 are clamped and connected.

[0041] When it is necessary to release the lock between the installation box 32 and the cabinet 11, the staff will insert one end of the handle 46 into the interior of the limit seat 41. The handle 46 is a key specifically used to release the lock. When one end of the handle 46 is engaged with one end of the socket 42, the handle 46 is rotated. The handle 46 will drive the shaft 43 to rotate through the socket 42. The rotation of the shaft 43 will drive the card plate 45. As the installation box 32 is moving and powered on, one end of the shaft 43 will just hit the inner wall of the cabinet 11, positioning the card seat 44 and the card plate 45, so as to ensure that the opening position of the card plate 45 will be engaged with the outer wall at the middle position of the card seat 44 when it rotates, ensuring the accuracy of the engagement connection. The card seat 44 and the card plate 45 are engaged and connected to lock the installation box 32 and the cabinet 11 together to prevent the installation box 32 from sliding on the top of the installation plate 31.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
