Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an electrical protection device for electrical installation. Background Art

[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. Electrical work must be performed by personnel who have undergone professional training, passed the examination, and hold an electrical work operation certificate. When installing electrical equipment, it is often necessary to protect the electrical equipment through the casing.

[0003] The existing patent CN216451623U provides a safety protection device for electrical installation, which "adopts a heat-absorbing copper sheet to absorb the heat inside the protective shell, and the heat generated by the electrical equipment can be transferred to the heat-absorbing copper sheet. A plurality of fins can increase the contact area between the heat-absorbing copper sheet and the air, and the heat absorption efficiency is high. The fan can be turned on, and the fan can cool the electrical equipment inside the protective shell, and at the same time dissipate the heat of the heat-absorbing copper sheet and the fins." However, this heat dissipation method is easily affected by the external environment. If the outside temperature is high, the temperature of the heat-absorbing copper sheet and the fins themselves is high, and it is not easy to absorb heat. The fan is set far away from the heat-absorbing copper sheet and the fins, and it is not possible to dissipate heat well. In view of this, a safety protection device for electrical installation is now proposed. Utility Model Content

[0025] A cooling mechanism is arranged in the electrical protection box housing 1, and is used to cool the electrical protection box housing 1. The cooling mechanism includes a semiconductor cooling sheet 3, and the semiconductor cooling sheet 3 is fixedly installed in the inner wall of the top plate of the electrical protection box housing 1;

[0026] The disassembly and assembly mechanism is arranged on the electrical protection box cabinet door 2. The disassembly and assembly mechanism is used for quickly disassembling the dustproof net 7 for replacement. The disassembly and assembly mechanism includes four fixed columns 8 and four card slots 9. The four fixed columns 8 are fixedly installed on the left surface of the dustproof net 7, and the four card slots 9 are respectively opened on the outer surfaces of the four fixed columns 8.

[0027] Furthermore, the cooling mechanism also includes a cooling fin 4 and a cooling fan 5 . The cooling fin 4 is fixedly mounted on the lower surface of the semiconductor refrigeration fin 3 , and the cooling fan 5 is fixedly mounted on the lower surface of the cooling fin 4 .

[0030] Furthermore, the disassembly and assembly mechanism also includes four fixed rods 13 and four clamping blocks 14. The four fixed rods 13 are respectively slidably mounted in the inner walls of the four sliding holes 12. The four clamping blocks 14 are fixedly installed at the lower ends of the four fixed rods 13, and the lower surfaces of the four clamping blocks 14 are all inclined.

[0031] Furthermore, the disassembly and assembly mechanism also includes four springs 15, and the four springs 15 are fixedly mounted on the upper surfaces of the four blocks 14, and the upper ends of the four springs 15 are respectively fixedly mounted on the inner walls of the four spring grooves 11. When the electrical protection device for electrical installation is used, the semiconductor refrigeration sheet 3 is connected to an external power supply, and the semiconductor refrigeration sheet 3 starts cooling. At this time, the cold air produced by the semiconductor refrigeration sheet 3 is transmitted through the cooling sheet 4, and the cold air is transmitted to the electrical protection box housing 1 through the cooling fan 5 for cooling treatment, and the semiconductor refrigeration sheet 3 is connected to the external power supply, and the semiconductor refrigeration sheet 3 starts cooling. The heat generated by the sheet 3 itself will be discharged through the cooling fan 6. At this time, the fixing column 8 fixedly installed on the left surface of the dustproof net 7 is inserted into the slot 10. At this time, the fixing column 8 hits the inclined surface of the block 14 and applies an upward thrust to the block 14, so that the block 14 moves upward. While moving, the block 14 applies pressure to the spring 15 fixedly installed on the upper surface to cause it to shrink. At the same time, the block 14 applies an upward thrust to the fixing rod 13 fixedly installed on the upper surface to make it slide upward in the sliding hole 12. At this time, the fixing column 8 continues to be inserted into The card block 14 is in the slot 10, and at this time, the card block 14 passes through the card slot 9 formed on the outer surface of the fixed column 8. At this time, the card block 14 is no longer under pressure, and the spring 15 is no longer under force. The spring 15 expands, and the spring 15 applies a downward thrust to the card block 14 fixedly installed on the lower surface, so that it moves downward and is engaged in the card slot 9 to limit and fix the fixed column 8. When it needs to be disassembled, an upward pulling force is applied to the fixing rod 13, and the fixing rod 13 drives the card block 14 fixedly installed at the lower end to move upward, so that the card connection limit with the fixed column 8 can be released, and the card block 14 can be pulled out at this time. After the dust-proof net 7 is disassembled, the electrical protection device for electrical installation can be cooled by the semiconductor refrigeration sheet 4. The produced cold air can be transferred to the electrical protection box casing 1 through the cooling sheet 4 and the cooling fan 5 to effectively cool down the interior of the electrical protection box. Moreover, the electrical protection box casing 1 is not subjected to heat exchange treatment and is protected from the influence of the external environment. It can effectively cool down the interior of the electrical components and maintain a suitable working temperature. The dust-proof net 7 can be quickly disassembled and assembled by the snap-on structure, and the disassembly and assembly speed is fast, so the dust-proof net 7 can be quickly replaced, which is more convenient.

[0032] Working principle: When the electrical protection device for electrical installation is used, the semiconductor refrigeration sheet 3 is connected to an external power supply, and the semiconductor refrigeration sheet 3 starts cooling. At this time, the cold air produced by the semiconductor refrigeration sheet 3 is transmitted through the cooling sheet 4, and the cold air is transferred to the electrical protection box housing 1 through the cooling fan 5 for cooling treatment, and the heat generated by the semiconductor refrigeration sheet 3 itself will be discharged through the cooling fan 6. At this time, the fixed column 8 fixedly installed on the left surface of the dustproof net 7 is inserted into the slot 10. At this time, the fixed column 8 hits the inclined surface of the card block 14 and applies an upward thrust to the card block 14, so that the card block 14 moves upward. While moving, the card block 14 applies pressure to the spring 15 fixedly installed on the upper surface to cause it to shrink. At the same time, the block 14 applies an upward thrust to the fixing rod 13 fixed on the upper surface, so that it slides upward in the sliding hole 12. At this time, the fixing column 8 continues to be inserted into the slot 10. At this time, the block 14 passes through the slot 9 opened on the outer surface of the fixing column 8. At this time, the block 14 is no longer under pressure, and the spring 15 is no longer under force. The spring 15 expands, and the spring 15 applies a downward thrust to the block 14 fixed on the lower surface, so that it moves downward and is engaged in the slot 9 to limit and fix the fixing column 8. When it needs to be disassembled, an upward pulling force is applied to the fixing rod 13, and the fixing rod 13 drives the block 14 fixed at the lower end to move upward, so that the engagement limit with the fixing column 8 can be released. At this time, the dustproof net 7 can be pulled out to complete the disassembly.
