[0002] In 10kV distribution networks, FTUs (Fan-to-Unit Transmission Units) are core equipment for distribution network automation and need to operate for extended periods in outdoor environments characterized by high temperatures, humidity, dust, and strong electromagnetic interference. Existing protective enclosures generally have the following shortcomings: current power equipment relies on fan power for cooling, but during hot periods, the high air temperature results in hot airflow, leading to poor cooling performance and requiring significant time for cooling.

[0003] To address the aforementioned issues, existing patent (CN116345339A) discloses an auxiliary heat dissipation device for power equipment, comprising a power equipment cabinet and a cabinet door. A connecting handle is fixedly connected to the front of the cabinet door. A refrigeration mechanism is installed at the upper part of the cabinet door's interior. A blower mechanism is movably connected to the bottom surface of the refrigeration mechanism. A limiting mechanism is threadedly connected to the lower part of the refrigeration mechanism. A heat dissipation plate is fixedly connected to the right end of the power equipment cabinet. The power equipment cabinet is movably connected to the back of the cabinet door. The refrigeration mechanism includes a refrigeration unit and a limiting unit, arranged sequentially from top to bottom. This heat dissipation device for power equipment, by incorporating a condenser pipe, a fan, and a metal frame, can blow cool air in hot weather, effectively dissipating heat from the power equipment inside the cabinet and achieving optimal heat dissipation, thus shortening the heat dissipation time.

[0004] However, in the aforementioned existing technologies, the active heat dissipation method that combines a refrigeration mechanism and a blower mechanism, the refrigeration unit includes components such as a compressor and a condenser, which can quickly reduce the internal temperature of the cabinet. However, this method relies on power supply, and the refrigeration equipment is prone to failure during long-term operation, resulting in high maintenance costs. In addition, in outdoor environments, the heat dissipation effect may be affected by unstable power supply. Utility Model Content

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 6This utility model provides a power protection housing 1 for a 10kV line switch terminal repair device, including a protective housing 1, a cover 2, and a lead connector body 3. The cover 2 is detachably connected to the protective housing 1 and is located below the protective housing 1. The lead connector body 3 is fixedly connected to the protective housing 1 and is located above the protective housing 1, and the lead connector body 3 penetrates through the protective housing 1. The cover 2 has a slide rail 201, a ventilation hole 202, and a dustproof net 203. The slide rail 201 is slidably connected to the protective housing 1 and is located outside the cover 2. The ventilation hole 202 is fixedly connected to the cover 2 and penetrates through the cover 2. The dustproof net 203 is fixedly connected to the cover 2 and is located inside the cover 2.

[0023] In this embodiment, the cover 2 is pulled outwards, and the FTU fault intelligent sensing and self-healing device is installed inside the protective housing 1. The outgoing connector body 3 is used for external wiring of the device. The outgoing connector body 3 is made of stainless steel and has good corrosion resistance. The cover 2 is slid to the bottom of the protective housing 1 via the slide rail 201 to support the FTU fault intelligent sensing and self-healing device. The cover 2 is provided with multiple ventilation holes 202, which are arranged in a circular array. The ventilation holes 202 are used for heat dissipation of the device. The dustproof mesh 203 is made of 300-mesh stainless steel. The dustproof mesh 203 blocks external dust. The dust particle size is larger than the mesh size of the dustproof mesh 203, so that dust cannot enter the protective housing 1, while air can circulate freely, thereby achieving the dual purpose of efficient heat dissipation and dust prevention. This method can effectively solve the problem.

[0024] Furthermore, the cover 2 also has a connecting block 204 and a push plate 205. The connecting block 204 is slidably connected to the protective outer shell 1 and is located below the slide rail 201. The push plate 205 is fixedly connected to the connecting block 204 and is located outside the connecting block 204.

[0025] In this embodiment, the connecting block 204 is slid by the push plate 205, thereby causing the cover 2 to slide, which facilitates the installation and removal of the cover 2.

[0026] Furthermore, the protective housing 1 has a sealing groove 101, a sealing ring 102, and a slide rail groove 103. The sealing groove 101 is disposed on the outside of the slide rail 201. The sealing ring 102 is fixedly connected to the sealing groove 101 and is located inside the sealing groove 101. The slide rail groove 103 is fixedly connected to the protective housing 1 and is located inside the protective housing 1.

[0027] In this embodiment, a sealing groove 101 is provided at the splicing edge of the protective shell 1 and the shell cover 2. A sealing ring 102 made of EPDM rubber is installed in the groove. The sealing ring 102 has good weather resistance, water resistance and elasticity, and fits tightly with the sealing groove 101 to form an efficient sealing barrier, effectively preventing rainwater and dust from entering. The slide rail groove 103 is used for positioning the device when it is installed on the protective shell 1.

[0028] Furthermore, the cable outlet connector body 3 has a mounting plate 301 and a fluororubber sealing ring 302. The mounting plate 301 is fixedly connected to the cable outlet connector body 3 and is located inside the cable outlet connector body 3. The fluororubber sealing ring 302 is detachably connected to the mounting plate 301 and is located above the mounting plate 301.

[0029] In this embodiment, the cable of the FTU fault intelligent sensing and self-healing device passes through the outgoing connector body 3, and the fluororubber sealing ring 302 is installed between the outgoing connector body 3 and the cable. The mounting plate 301 is used to support the fluororubber sealing ring 302.

[0030] Furthermore, the cable outlet connector body 3 also has a silicone rubber sealing ring 303 and a clamping nut 304. The silicone rubber sealing ring 303 is detachably connected to the fluororubber sealing ring 302 and is located above the fluororubber sealing ring 302. The clamping nut 304 is threadedly connected to the cable outlet connector body 3 and is located above the silicone rubber sealing ring 303.

[0031] In this embodiment, the silicone rubber sealing ring 303 is installed above the fluororubber sealing ring 302. By tightening the clamping nut 304, the double-layer sealing ring is compressed and deformed, tightly wrapping the cable and preventing rainwater from entering from the cable outlet. The waterproof rating can reach IPX3.

[0032] The beneficial effects of this utility model are as follows: The FTU fault intelligent sensing and self-healing device is installed inside the protective shell 1 via the slide rail groove 103. The slide rail 201 slides outside the sealing ring 102 and moves the connecting block 204 by pushing the push plate 205, so that the shell cover 2 is installed below the protective shell 1, thus supporting the FTU fault intelligent sensing and self-healing device. The ventilation hole 202 is used for heat dissipation of the device. The dustproof net 203 blocks external dust. The dust particle size is larger than the mesh size of the dustproof net 203, so that dust cannot enter the protective shell 1, thus preventing air from entering. The device allows for free flow, achieving both efficient heat dissipation and dust prevention. The cable passes through the outlet connector body 3. Between the outlet connector body 3 and the cable, the inner fluororubber sealing ring 302 and the outer silicone rubber sealing ring 303 are installed in sequence. By tightening the clamping nut 304, the double-layer sealing rings are compressed and deformed, tightly wrapping the cable and preventing rainwater from entering from the outlet. This facilitates quick and easy installation and maintenance of the device, creating a highly efficient waterproof and dustproof barrier. Furthermore, the cover 2 achieves both efficient heat dissipation and dust prevention, providing a stable and clean operating environment.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
