Technical Field

It has overload and short circuit protection functions and can be used to protect circuits or motors from overload and short circuits. It can also be used for infrequent switching and starting of circuits under normal conditions.

[0003] In some high-temperature environments, such as boiler rooms and smelting workshops, the performance and lifespan of residual current devices (RCDs) may be affected by excessively high ambient temperatures. Therefore, it is necessary to improve the heat dissipation design of RCDs to enhance their stability and reliability in high-temperature environments and ensure normal operation even in harsh working conditions.

[0017] Beneficial effects

[0018] This invention provides a residual current device (RCD) with a leakage current protection component. Compared with the prior art, it has the following advantages:

[0019] 1.

[0028] It should be noted that in the description of the embodiments of this application, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 5 This application provides a residual current device (RCD) with a leakage protection component, including a heat-conducting base plate 1, a heat dissipation component 2 disposed on one side of the heat-conducting base plate 1, and an auxiliary component 3 disposed on one side of the heat-conducting base plate 1. The heat dissipation component 2 includes a heat-conducting shell 21, an X-shaped heat-conducting plate 24 fixedly connected between the inner walls of the heat-conducting shell 21, an RCD body 22 fixedly mounted on the outer wall of the heat-conducting shell 21, a heat-conducting contact 23 fixedly connected to one side of the RCD body 22, the heat-conducting contact 23 being connected to a heating element inside the RCD body 22, and one end of the heat-conducting contact 23 being fixedly connected to the inside of the side wall of the heat-conducting shell 21. A cooling fan 25 is fixedly mounted between the inner walls of one end of the heat-conducting shell 21.

[0031] In practice: when the heating element inside the leakage current protector body 22 generates heat, it will conduct the heat to the heat-conducting housing 21 through the heat-conducting contact 23. The heat-conducting housing 21 will then transfer the heat to the X-shaped heat-conducting plate 24. After that, the cooling fan 25 can be activated to accelerate the airflow inside the heat-conducting housing 21, thereby removing the heat from the X-shaped heat-conducting plate 24 to achieve rapid cooling.

[0032] Reference Figures 1 to 5 In one aspect of this embodiment, the auxiliary component 3 includes heat dissipation fins 31, which are fixedly connected to one side of the heat-conducting base plate 1. The heat-conducting base plate 1 has threaded holes 32 inside. Dust covers 33 are fixedly installed at both ends of the heat-conducting housing 21. A support block 34 is fixedly connected to one side of the heat-conducting base plate 1.

[0033] In practice: the remaining heat will continue to be transferred to the heat-conducting base plate 1, and the heat dissipation area will be expanded by the heat dissipation fins 31 for auxiliary heat dissipation. The threaded hole 32 is used to fix the heat-conducting base plate 1 with the matching bolts. The dust cover 33 is used to prevent a large amount of dust from entering the interior of the heat-conducting shell 21. The support block 34 is used to provide certain support for the heat-conducting shell 21.

[0034] All electrical devices in this plan are powered by an external power source.

[0035] Working principle: After the heating element inside the leakage current protector body 22 generates heat, this heat is first rapidly conducted to the heat-conducting housing 21 via the heat-conducting contact 23. The heat-conducting housing 21 then transfers the heat to the X-shaped heat-conducting plate 24. When the heat accumulates to a certain level, the cooling fan 25 automatically starts. The airflow generated by the operation of the cooling fan 25 greatly accelerates the airflow speed inside the heat-conducting housing 21, causing the heat on the X-shaped heat-conducting plate 24 to dissipate rapidly.

[0036] Meanwhile, the remaining heat continues to be conducted to the heat-conducting base plate 1. The heat dissipation fins 31 on the heat-conducting base plate 1 significantly increase the heat dissipation area, effectively improving the auxiliary heat dissipation effect. For installation, the heat-conducting base plate 1 is fixed in place using threaded holes 32 and matching bolts. Furthermore, the dust cover 33 tightly covers the exterior of the heat-conducting housing 21, preventing excessive dust ingress and ensuring the cleanliness of the internal structure. Support blocks 34 are evenly distributed at the bottom of the heat-conducting housing 21, providing stable support.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
