Description

Technical Field

[0001] This utility model belongs to the technical field of power line overload protection equipment, specifically relating to a power line overload protection switching device. Background Technology

[0002] Overload protection devices for power lines are electrical devices used to monitor, control, and cut off abnormal currents in power systems. They are primarily used to prevent safety accidents such as overheating, insulation damage, and even fires caused by overload or short-circuit faults. These devices detect current changes in real time and automatically disconnect the circuit when the current exceeds a set threshold, ensuring the safety of the power grid and the stable operation of electrical equipment. Common overload protection devices include circuit breakers, fuses, and thermal relays, which are characterized by fast response and reliable operation. They are widely used in power distribution systems, industrial control, and household appliances, and are important safety protection devices for power systems.

[0003] There are many types of overload protection devices for power lines, among which circuit breakers are the most common. Circuit breakers can automatically disconnect the circuit when the circuit is overloaded or short-circuited, thereby ensuring the safe operation of the power system. However, traditional circuit breakers are usually installed in parallel, which can easily lead to insufficient spacing between circuit breakers and thus cause poor heat dissipation.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a power line overload protection switching device, including,

[0027] The protection mechanism 100 includes two circuit breakers 110 installed in parallel;

[0028] The heat dissipation mechanism 200 includes a spacing adjustment component 210 for adjusting the installation distance between the two circuit breakers 110, and a heat dissipation component 220 for assisting the heat dissipation of the two circuit breakers 110.

[0029] The spacing adjustment component 210 and the heat dissipation component 220 work together to adjust the distance between the parallel-installed circuit breakers 110, thereby optimizing the heat dissipation effect. This solves the problem of poor heat dissipation caused by insufficient spacing when multiple circuit breakers 110 are installed in parallel. By controlling the installation spacing of the circuit breakers 110, the heat dissipation performance is effectively improved, ensuring stable operation of the equipment.

[0030] Specifically, the spacing adjustment component 210 includes a stud 211 fixedly installed on one side of the circuit breaker 110, and a threaded sleeve 212 threadedly installed on the surface of the stud 211 and adjusting the installation spacing between the two circuit breakers 110.

[0031] Furthermore, a protective pad 213 is fixedly installed on one side of the threaded sleeve 212, and a positioning groove 120 for use with the protective pad 213 is provided on one side of the circuit breaker 110.

[0032] The protective pad 213 is used to protect the surface of the circuit breaker 110. The positioning groove 120 and the protective pad 213 cooperate to position and install the parallel circuit breakers 110.

[0033] Preferably, the size of the protective pad 213 is adapted to the size of the positioning groove 120, and the protective pad 213 is made of rubber with protective function.

[0034] Furthermore, the heat dissipation component 220 includes a mounting slot plate 221 fixedly installed on one side of the circuit breaker 110, a fixed heat-conducting plate 222 disposed between the two mounting slot plates 221 for heat dissipation, a movable heat-conducting plate 223 flexibly installed on one side of the fixed heat-conducting plate 222 for transferring heat to the cabinet, and a thermally conductive silicone 224 fixedly installed on one side of the movable heat-conducting plate 223 and in contact with the cabinet.

[0035] The mounting slot 221 is made of thermally conductive metal material. The fixed heat-conducting plate 222 conducts the heat generated by the circuit breaker 110 and transfers it to the cabinet through the movable heat-conducting plate 223 and the thermally conductive silicone 224, which plays a role in heat dissipation for the circuit breaker 110. The thermally conductive silicone 224 can effectively reduce the contact thermal resistance with the cabinet and improve the heat transfer efficiency.

[0036] Specifically, the top of the mounting slot plate 221 is threaded with mounting bolts 225 for fixing the heat-conducting plate 222, and the surface of the heat-conducting plate 222 is provided with grooves for inserting the mounting bolts 225.

[0037] The heat-conducting plate 222 is fixedly installed by inserting the end of the mounting bolt 225 into the groove, thereby improving the stability of the heat-conducting plate 222 in use.

[0038] Furthermore, a storage groove 226 for installing a movable heat-conducting plate 223 is provided on one side of the fixed heat-conducting plate 222. The storage groove 226 is provided with two springs 227 that maintain elastic pressure on the movable heat-conducting plate 223.

[0039] The other end of the spring 227 is fixedly connected to the movable heat-conducting plate 223. The surface of the movable heat-conducting plate 223 is in contact with the inside of the storage groove 226. The spring 227 is used to maintain elastic pressure on the movable heat-conducting plate 223, so that the movable heat-conducting plate 223 always pushes the thermal conductive silicone 224, so that the thermal conductive silicone 224 has sufficient contact with the cabinet, improving the heat transfer efficiency and heat dissipation effect.

[0040] When in use, install several required circuit breakers 110 in the cabinet. After fixing one of the circuit breakers 110, adjust the position of the circuit breakers 110 on its side. The distance between the circuit breakers 110 needs to be adjusted according to the rated power of the line to ensure the heat dissipation performance of the circuit breakers 110.

[0041] After fixing the installation position of the side circuit breaker 110, rotate the threaded sleeve 212 on the stud 211 so that the threaded sleeve 212 moves closer to the side circuit breaker 110 until the threaded sleeve 212 drives the protective pad 213 to engage inside the positioning groove 120. Then, the side circuit breaker 110 is completely fixed and installed, and the working distance between the circuit breakers 110 is adjusted.

[0042] During the use of circuit breaker 110, heat is generated. The mounting slot plate 221 and the fixed heat-conducting plate 222 conduct the heat out and transfer it to the cabinet through the movable heat-conducting plate 223 and the thermally conductive silicone 224, which plays a role in heat dissipation for circuit breaker 110.

[0043] In summary, by cooperating with the spacing adjustment component 210 and the heat dissipation component 220, the distance between the circuit breakers 110 installed in parallel can be adjusted, thereby optimizing the heat dissipation effect. This solves the problem of poor heat dissipation caused by insufficient spacing when multiple circuit breakers 110 are installed in parallel. By controlling the installation spacing of the circuit breakers 110, the heat dissipation performance is effectively improved, ensuring stable operation of the equipment.
