[0002] A leakage protector is an electrical safety device, mainly used to prevent electric shock accidents caused by leakage in electrical equipment and electrical lines, and as a supplementary protection for direct contact under certain conditions. The main function of a leakage protector is to detect leakage current in the circuit and cut off the power supply when the leakage current is too large to protect the safety of personnel and equipment. Leakage protectors are usually installed in low-voltage circuits. When leakage and electric shock occur, and the operating current value specified by the protector is reached, it will immediately operate within a limited time to automatically disconnect the power supply for protection.

[0024] In order to solve the problem that the leakage protector is not convenient for heat dissipation, when the protector body 1 needs to be heat-dissipated, the rotating motor 5 can be started, and the rotating motor 5 can be used to drive the rotation of the rotating rod, and the rotation of the rotating rod can be used to drive the fan blades 6 to rotate. When the fan blades 6 rotate, wind force will be generated and blow toward one side of the guide block 7. By setting the guide block 7, the wind force blowing toward the guide block 7 can be divided into two wind flows, and the two wind flows can flow into the connecting frames 9 on both sides of the heat dissipation box 4. The setting of the air inlet 8 can ensure that a steady supply of external air enters the heat dissipation box 4. After the wind force flows into the connecting frame 9, it will flow into the side frame 10 through the connecting frame 9, and the wind flow can blow away the high-temperature air in the side frame 10. After the high-temperature air is blown away, the temperature of the inner wall of the side frame 10 will drop. Since the two groups of side frames 10 are fixedly connected to the two sides of the protector body 1, the heat dissipation effect can be provided for both sides of the protector body 1.

[0026] When the wind enters the side frame 10, it can be blown out from the side frame 10 through the first vent. When the wind passes through the first vent, it will blow the sealing plate 12 upward, and the sealing plate 12 will flip through the rotating shaft, so that the top of the first vent is opened. When there is no wind, the sealing plate 12 will flip downward by gravity until one side of the sealing plate 12 hits the positioning plate 13, thereby closing the first vent to prevent impurities and dust from falling into the inner wall of the side frame 10.
[0027] Reference Figure 4 A second vent is provided at the bottom of the side frame 10, and a blocking net 14 is fixedly connected to the inner wall of the second vent.
[0028] By setting a second vent at the bottom of the side frame 10, wind can flow out to the bottom of the side frame 10 through the second vent, and by setting a blocking net 14 on the inner wall of the second vent, insects can be prevented from entering the inner wall of the side frame 10 from the second vent.

One side of the separation block 15 is provided with air holes. There are multiple groups of air holes, which are distributed in parallel on one side of the separation block 15 .

[0031] Reference Figure 5 A wire insertion port 11 is fixedly connected to the top of the protector body 1, and a sealing gasket 16 is fixedly connected to the inner wall of the wire insertion port 11. The sealing gasket 16 is made of rubber, and a circular hole is opened on the inner wall of the sealing gasket 16.

By setting a rubber sealing gasket 16 on the inner wall of the wire insertion port 11, after the wires are installed in the wire insertion port 11, the sealing gasket 16 can fit the outer wall of the wires to prevent leakage caused by exposed battery cells.
[0033] Reference Figure 1 A filter screen 17 is fixedly connected to the inner wall of the air inlet 8 , and the filter screen 17 is arranged on one side of the rotating motor 5 .
[0034] By arranging the filter 17 on the inner wall of the air inlet 8 , when the external air enters the heat sink 4 , the air entering the heat sink 4 can be easily filtered through the filter 17 to prevent impurities from entering the heat sink 4 .
[0035] Working principle: In order to solve the problem that the leakage protector is not convenient for heat dissipation, when the protector body 1 needs to be heat-dissipated, the rotating motor 5 can be started, and the rotating motor 5 can be used to drive the rotation of the rotating rod, and the rotation of the rotating rod can drive the fan blade 6 to rotate. When the fan blade 6 rotates, wind force will be generated and blow toward one side of the guide block 7. By setting the guide block 7, the wind force blowing toward the guide block 7 can be divided into two wind flows, and the two wind flows can flow into the connecting frames 9 on both sides of the heat dissipation box 4.

After the wind flows into the connection frame 9, it will flow into the side frame 10 through the connection frame 9, and the wind can blow away the high-temperature air in the side frame 10. After the high-temperature air is blown away, the temperature of the inner wall of the side frame 10 will drop. Since the two sets of side frames 10 are fixedly connected to the two sides of the protector body 1, the heat dissipation effect can be provided for the two sides of the protector body 1. By arranging a V-shaped separation block 15 on the inner wall of the side frame 10, when the wind blows from the connection frame 9 into the side frame 10, it is convenient to separate the wind through the V-shaped separation block 15. The airflow is divided into the first vent and the second vent, so that the wind can fully contact the air in the side frame 10 to facilitate cooling, and the wind holes provided on the separation block 15 can allow part of the wind to pass through the separation block 15 and dissipate heat to the area on the other side of the separation block 15. An upward wind flow can be blown out of the side frame 10 through the first vent, and when the wind flows through the first vent, it will blow the sealing plate 12 upward, and the sealing plate 12 will flip over by the rotating shaft, so that the top of the first vent is opened, and when there is no wind, the sealing plate 12 will flip downward by gravity until one side of the sealing plate 12 hits the positioning plate 13, thereby opening the top of the first vent. The air vent is closed to prevent impurities and dust from falling into the inner wall of the side frame 10. By setting a second vent at the bottom of the side frame 10, a downward wind flow can be discharged from the bottom of the side frame 10 through the second vent. By setting a blocking net 14 on the inner wall of the second vent, insects can be prevented from entering the inner wall of the side frame 10 from the second vent. By setting a wire plug port 11 at the top of the protector body 1, it is convenient to install the wires on the top of the protector body 1.
