[0002] Power protection is a technical measure that automatically and quickly disconnects faulty equipment from the system or issues alarm signals when a power system experiences a fault or is in an abnormal operating state, in order to ensure the safe and stable operation of the power system and prevent short circuit faults, overloads, overvoltages, or frequency anomalies. Power protection devices include electromagnetic protection devices, integrated circuit protection devices, microcomputer protection devices, or intelligent protection devices, and there are many different types of power protection devices on the market.

[0003] For example, Chinese Patent No. CN114894087B discloses a power protection device. This power protection device includes an outlet pressure plate and a position detection unit. The outlet pressure plate includes a fixed component with movable connection and an active switching component, the active switching component including a connecting piece. The position detection unit includes at least one optical detection component used to determine the position of the connecting piece; wherein the position includes an engaged position and an disengaged position. By adding an optical detection component to the outlet pressure plate, the engaged / disengaged status of the outlet pressure plate can be detected without affecting the original circuit loop, and pressure plate faults can be detected in a timely manner, alerting maintenance personnel to perform repairs.

The lower end of the air supply pipe 26 is installed on the base 2. The air pump 28 is installed on the inside of the filter box 27, and the filter box 27 is connected to the base 2 by a slot.

[0059] Using the above technical solution, a cleaning structure is formed by combining an extraction hood 18, an air supply pipe 26, a filter box 27, and an extraction pump 28, which can effectively collect dust.

[0060] As attached Figure 1 and attached Figure 2 As shown, a heat sink substrate 3 is installed on the lower interior of the housing 1, and a power protection unit 4 is installed on the upper part of the heat sink substrate 3. The power protection unit 4 protects the power system. An auxiliary heat dissipation mechanism is provided on the lower interior of the housing 1 to assist the power protection unit 4 in heat dissipation. Ventilation plates 13 are symmetrically installed on the outer side of the housing 1 to achieve ventilation. A cleaning mechanism that can automatically collect dust is provided on the outer side of the ventilation plate 13 to effectively clean the ventilation plate 13 and ensure the heat dissipation effect.

[0061] As attached Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the auxiliary heat dissipation mechanism includes a heat sink substrate 3, heat dissipation fins 5, a temperature sensor 6, a controller 7, and a heat sink 8. The heat sink substrate 3 is made of a high thermal conductivity metal material. The heat sink substrate 3 quickly absorbs the heat generated by the power protection unit 4. Heat dissipation fins 5 are installed at equal intervals below the heat sink substrate 3. The heat dissipation fins 5 increase the contact area between the heat of the power protection unit 4 and the air. A temperature sensor 6 is installed on the upper rear side of the heat sink substrate 3. The temperature sensor 6 monitors the temperature of the heat sink substrate 3 in real time. The controller 7 is connected to the rear side of the temperature sensor 6. A heat sink 8 is set on the rear side of the heat sink substrate 3. The controller 7 controls the opening and closing of the heat sink 8. The heat sink 8 is installed on the rear side of the housing 1. The heat sink 8 is symmetrically arranged on the left and right sides to achieve efficient heat dissipation. A dustproof plate 9 is installed on the rear side of the heat sink 8 to prevent dust from entering the housing 1 through the heat sink 8.

[0062] As attached Figure 2 Appendix Figure 3 and attached Figure 4As shown, the auxiliary heat dissipation mechanism also includes a heat-conducting block 10, a water-cooling pipe 11, and a chiller 12.

The chiller 12 is installed on the outside of the water-cooling pipe 11 to effectively dissipate heat, avoid the formation of local hot spots, ensure the uniformity of the internal temperature field, and facilitate the normal operation of the power protection unit 4.

[0063] As attached Figure 1 Appendix Figure 6 and attached Figure 7 As shown, the mounting bracket 14 is slidably connected to the housing 1 via the support spring 15. When the ventilation plate 13 needs to be removed, the handle 16 is pulled outward. The mounting bracket 14 is fixed on the inner side of the handle 16. The handle 16 drives the mounting bracket 14 to move, so that the mounting bracket 14 is disengaged from the slot connection with the ventilation plate 13. The support spring 15 is installed on the outer side of the mounting bracket 14. The mounting bracket 14 squeezes the support spring 15, so that the ventilation plate 13 connected to the slot can be removed from the housing 1. The new ventilation plate 13 is placed into the housing 1. The handle 16 is released, and the elastic action of the support spring 15 pushes the mounting bracket 14 to reset, so that the mounting bracket 14 and the ventilation plate 13 are connected in the slot, thus fixing the ventilation plate 13.

[0064] As attached Figure 8 and attached Figure 9 As shown, the cleaning mechanism includes a cleaning brush 17, an adjusting block 19, an adjusting rod 20, and a drive motor 21. The drive motor 21 is mounted on the rear end of the adjusting rod 20. When the drive motor 21 is turned on, it rotates the adjusting rod 20. The adjusting block 19 is threaded onto the outer side of the adjusting rod 20, causing the adjusting rod 20 to move. A connecting block 23 is fixed below the adjusting block 19, and the cleaning brush 17 is fixed below the connecting block 23. The connecting block 23 causes the cleaning brush 17 to move, allowing it to fit tightly against the outer side of the ventilation plate 13. The cleaning brush 17 cleans the ventilation plate 13. A fixing plate 22 is tightly attached to the bottom of the 17, and the fixing plate 22 is fixed to the outside of the outer shell 1, effectively limiting the cleaning brush 17. A first rubber plate 24 is tightly attached to the right side of the connecting block 23, and a second rubber plate 25 is tightly attached to the left side of the connecting block 23. The first rubber plate 24 and the second rubber plate 25 are tightly attached to each other. When the connecting block 23 moves, since the cross-sections of the front and rear ends of the connecting block 23 are arc-shaped, the connecting block 23 is always tightly attached to the first rubber plate 24 and the second rubber plate 25, preventing dust from falling on the adjusting rod 20 and clogging the adjusting rod 20, and ensuring the normal sliding of the adjusting block 19.

[0065] As attached Figure 1 and attached Figure 5As shown, the cleaning mechanism also includes an extraction hood 18, an air supply pipe 26, a filter box 27, and an air pump 28. When the cleaning brush 17 cleans the ventilation plate 13, the extraction hood 18 is installed on the outside of the cleaning brush 17. The air pump 28 is turned on, and the air supply pipe 26 is installed on the outside of the extraction hood 18. The dust cleaned by the cleaning brush 17 is extracted by the extraction hood 18. The lower end of the air supply pipe 26 is on the base 2. The filter box 27 is connected to the internal slot of the base 2. The filter material is filled into the filter box 27. The dust is concentrated in the filter box 27 through the air supply pipe 26 to prevent the dust from floating.
