Description

Technical Field

[0001] This invention relates to the field of smart grid technology, and more specifically to a distribution box with a protective structure for smart grids. Background Technology

[0002] With the advancement of energy transition and the "dual-carbon" goals, the power system is rapidly upgrading towards digitalization and intelligence. As the core of the modern energy system, the smart grid has become a key infrastructure supporting the construction of new power systems and ensuring a safe and efficient energy supply. The smart grid represents an intelligent form of the power grid, built upon an integrated, high-speed, two-way communication network. By integrating advanced sensing and measurement technologies, advanced equipment technologies, advanced control methods, and advanced decision support system technologies, its core objective is to achieve a reliable, safe, economical, efficient, environmentally friendly, and secure power grid, driving the transformation of the power system from a traditional centralized model to a new collaborative architecture integrating power generation, grid, load, and storage.

[0003] Compared to traditional power grids, smart grids are composed of numerous automated transmission and distribution systems working together to achieve coordinated, efficient, and reliable operation of the entire power grid, possessing significant technological advantages. Smart grids have powerful self-healing capabilities, enabling them to sense the grid's operating status in real time, quickly isolate fault points, and complete self-repair, preventing the escalation and spread of faults. Simultaneously, smart grids can rapidly respond to fluctuations in the electricity market and the diverse electricity demands of enterprises and users, achieving optimal allocation of power resources. As an indispensable core terminal device in the smart grid system, the distribution box undertakes key functions such as power distribution, line protection, power data acquisition, and fault early warning. It is a crucial "last mile" hub connecting the power grid and end users, and its operational stability and security directly determine the overall functionality and power supply reliability of the smart grid.

[0004] In the actual operation of smart grids, distribution boxes need to be adapted to different application scenarios, including outdoor open-air environments, industrial plants, and residential communities. They face complex external working conditions for a long time, such as high and low temperature changes, rain and snow erosion, dust accumulation, external impact, and potential risks such as internal circuit overload, short circuit, and leakage. Most existing distribution boxes use traditional structural designs, with generally weak protection performance, which cannot meet the needs of complex scenarios. They are susceptible to corrosion from external environmental factors and have poor impact resistance, making them easily damaged after impact. In addition, their low heat dissipation efficiency is also a prominent problem, further affecting the stability of equipment operation.

[0005] Therefore, we propose a distribution box with a protective structure for smart grids. Summary of the Invention

[0006] The main objective of this invention is to provide a distribution box with a protective structure for smart grids. By setting up a first protective component and a second protective component, a dual external force protection system is constructed, solving the problem of poor impact and scratch resistance of traditional distribution boxes and extending the service life of the equipment. By installing an activated carbon adsorption plate at the air inlet at the lower end of the roof, dust and impurities in the air can be filtered, preventing them from entering the installation cavity and adhering to electrical components. The protective mesh plate snapped into the ventilation channel can block debris from entering, further ensuring a clean internal environment for the distribution box and reducing malfunctions caused by dust accumulation and moisture on electrical components. This design improves equipment operational stability. A heat-conducting plate is connected to the back panel near the distribution box body. This plate conducts heat from the mounting cavity to the back panel, while multiple parallel heat sinks on the outer side of the back panel quickly dissipate heat to the outside, achieving efficient heat conduction and dissipation. A fan is installed on the top cover of the distribution box, and a cavity is set inside the ceiling. When the fan operates, it blows air into the mounting cavity, causing hot air to be discharged through the ventilation slots and channels, while cold air from outside enters the mounting cavity through the air inlet and the cavity, forming a complete air circulation, accelerating airflow, and further improving heat dissipation efficiency. This effectively solves the problems in the background technology.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A distribution box with a protective structure for smart grids includes a distribution box body, a box door, a concrete pouring platform for assembling mounting plates, and a back plate located on the side of the distribution box body away from the box door. Both ends of the back plate on the side near the distribution box body are vertically connected to heat-conducting plates, and the end of the heat-conducting plate away from the back plate is snapped to both ends of the distribution box body through a positioning plate. The first protective component is located at both ends of the distribution box body and is assembled on the side of the heat-conducting plate away from the distribution box body. The second protective component is located on the side of the distribution box body away from the back panel and is installed on the side of the box door away from the distribution box body. The bottom of the distribution box body is fixedly connected to a base. The base and the back plate are assembled together on the mounting plate. The mounting plate is horizontally installed on the top of the concrete pouring platform. Bolts are pre-embedded on the top of the concrete pouring platform. Through holes for the pre-embedded bolts are provided at the four corners of the upper surface of the mounting plate. The top of the distribution box body is provided with a cover for installing a fan. The top of the cover is equipped with a canopy for protecting the upper part of the distribution box body. The distribution box body has an installation cavity inside. Ventilation slots and ventilation channels communicating with the installation cavity are provided at the lower parts of both ends of the distribution box body.

[0008] Specifically, the first protective component includes a side plate, a protective plate, a buffer layer, a support spring, and a first bolt. The side plate and the protective plate are both vertically arranged rectangular plate structures. The side plate is fixedly connected to one side of the heat-conducting plate by the first bolt. The side of the side plate away from the heat-conducting plate is connected to one side of the protective plate by the support spring. The buffer layer is fixedly glued to the side of the protective plate away from the support spring. The second protective component includes a vertically arranged rubber plate and support rods located at the four corners of one side of the rubber plate, with the end of the support rod away from the rubber plate vertically inserted into the door.

[0009] By adopting the above technical solution and setting up a first and second protective component, a dual external force protection system is constructed, which solves the problem of poor impact and scratch resistance of traditional distribution boxes and can extend the service life of the equipment. The first protective component consists of a side plate, a protective plate, a buffer layer, and a support spring, which are assembled at both ends of the distribution box body. When the equipment is impacted by an external force, the protective plate contacts the impact force first, the support spring undergoes elastic deformation to absorb most of the impact energy, and the buffer layer further weakens the remaining impact force, preventing the distribution box body from being directly deformed by force and preventing internal electrical components from being damaged by impact. The second protective component consists of a rubber plate and a support rod, which are assembled on the outside of the box door. The rubber plate can effectively resist external scratches and bumps, while the support rod maintains the distance between the rubber plate and the box door, preventing rainwater and dust from directly contacting the box door surface and improving the corrosion resistance in outdoor environments. Through the coordinated design of components such as the concrete pouring platform, mounting plate, positioning parts, and locking plate, the distribution box is firmly installed and adapts to the installation needs of different scenarios.

[0010] Specifically, the distribution box body is provided with a matching sealing element on the side near the box door. The sealing element is a vertically arranged rectangular frame structure. The side of the sealing element away from the distribution box body is embedded in the side of the box door. One end of the box door is rotatably connected to one side of the distribution box body, and the other end of the box door is fixedly connected to two sets of relatively parallel pull plates. Protective mesh plates are snapped onto the lower parts of both ends of the distribution box body at the location of the ventilation channel. The ventilation channel is inclined upward at the end away from the protective mesh plate and communicates with the lower part of the ventilation slot. A second cable hole is also provided at the bottom of the distribution box body, and a second sealing plug is fastened to the lower part of the second cable hole.

[0011] Specifically, the distribution box body is fixedly connected to a positioning seat adapted to the pull plate at one end away from the back plate. The pull plate is fixedly connected to the positioning seat by a second bolt. The distribution box body is also provided with positioning grooves adapted to the positioning plate at both ends near the sealing element. The sealing element is provided with an opening communicating with the installation cavity. Both ends of the distribution box body are provided with slots for installing heat-conducting plates. The slots are connected to the positioning slots. The back plate is provided with multiple sets of relatively parallel heat sinks on the side away from the distribution box body.

[0012] Specifically, the top of the mounting cavity is provided with a top plate for mounting a fan, and a cavity is provided above the top plate. The cavity is located inside the ceiling, and the fan blows air towards the mounting cavity. The bottom of the ceiling is provided with a buckle plate that is fitted onto the upper part of the outer side of the box cover. The buckle plate is a horizontally arranged rectangular frame structure. The lower end face of the buckle plate is provided with an air inlet for mounting the activated carbon adsorption plate. The air inlet is connected to the cavity.

[0013] Specifically, the mounting plate is a horizontally arranged rectangular plate structure. The first protective components are arranged in two sets that are relatively parallel to each other. The lower part of the back plate near the distribution box body is provided with a protrusion that engages with one side of the base. The lower part of the back plate away from the protrusion and the lower part of the base away from the back plate are both provided with slots that are adapted to the side of the positioning component.

[0014] By adopting the above technical solutions and setting up active and passive heat dissipation methods, the problem of low heat dissipation efficiency of traditional distribution boxes is solved, ensuring stable temperature of the equipment during long-term continuous operation. Passive heat dissipation: A heat-conducting plate is connected to the back panel near the distribution box body. The heat-conducting plate can conduct heat from the mounting cavity to the back panel. Multiple sets of parallel heat sinks on the outside of the back panel quickly dissipate heat to the outside, achieving efficient heat conduction and dissipation. Active heat dissipation: A fan is installed on the top cover of the distribution box, and a cavity is set in the ceiling. When the fan is working, it blows air into the mounting cavity, causing the hot air in the mounting cavity to be discharged through the ventilation slot and ventilation channel. External cold air enters the mounting cavity through the air inlet and the cavity, forming a complete air circulation, accelerating air flow, further improving heat dissipation efficiency, and thus extending the service life of the equipment.

[0015] Specifically, the upper surface of the mounting plate is fixedly snapped with positioning components on both sides. Two sets of positioning components are arranged in parallel. One end of the two sets of positioning components is connected to a baffle. The bottom end of the baffle is fixedly connected to the upper surface of the mounting plate. The end of the two sets of positioning components away from the baffle is provided with a insertion hole that matches the insertion rod. A limiting cavity is provided between the two sets of positioning components. A locking strip is fixedly connected to the center of the end of the positioning component near the positioning cavity. A base is fixed inside the limiting cavity. The base has a cable arrangement cavity inside, and the end of the base away from the baffle has a sealing groove.

[0016] Specifically, the upper surface of the mounting plate is provided with a groove that matches the embedded plate at the center of the end away from the baffle. The two sets of positioning members are engaged with locking plates at the ends away from the baffle. The locking plates are vertically connected to the insertion rods at both ends of the insertion holes. The bottom end of the locking plate is fixedly connected to the upper surface of the embedded plate at the center of the bottom. A sealing plate is fixedly attached to the upper part of the locking plate near the limiting cavity. The sealing plate is located in the sealing groove, which is connected to the cable arrangement cavity.

[0017] Specifically, the upper surface of the mounting plate is provided with a first cable hole, and a first sealing plug is provided in the first cable hole. The inner wall of the bottom end of the cable arrangement cavity is provided with a third cable hole that communicates with the first cable hole. A third sealing plug is fastened to the top of the third cable hole.

[0018] The beneficial effects of this invention are: (1) The smart grid distribution box with protective structure described in this invention constructs a dual external force protection system by setting a first protective component and a second protective component, which solves the problem of poor impact and scratch resistance of traditional distribution boxes and can extend the service life of the equipment. The first protective component consists of a side plate, a protective plate, a buffer layer and a support spring, which are assembled at both ends of the distribution box body. When the equipment is impacted by an external force, the protective plate contacts the impact force first, the support spring undergoes elastic deformation to absorb most of the impact energy, and the buffer layer further weakens the remaining impact force, avoiding direct deformation of the distribution box body and preventing damage to internal electrical components due to impact. The second protective component consists of a rubber plate and a support rod, which are assembled on the outside of the box door. The rubber plate can effectively resist external scratches and bumps, while the support rod maintains the distance between the rubber plate and the box door, preventing rainwater and dust from directly contacting the box door surface and improving the corrosion resistance in outdoor environments. Through the coordinated design of components such as concrete pouring platform, mounting plate, positioning parts and locking plate, the distribution box is firmly installed and adapted to the installation requirements of different scenarios. (2) The distribution box with protective structure for smart grid described in this invention has a rectangular frame structure sealing element between the distribution box body and the box door. The sealing element is embedded in one side of the box door to form a closed-loop sealing structure, which can effectively block rainwater and dust from entering the installation cavity. The base and the locking plate are sealed by the cooperation of the sealing plate and the sealing groove to achieve the sealing of the cable arrangement cavity and prevent rainwater from seeping in and damaging the cable. The cable enters the cable arrangement cavity through the cable channel preset in the concrete pouring platform, through the first cable hole and the third cable hole in sequence, and then through the second cable hole into the installation cavity, so as to achieve the orderly arrangement of the cable, improve the stability of the cable connection, and facilitate the later maintenance and repair. By installing the activated carbon adsorption plate at the air inlet at the lower end of the ceiling, the dust and impurities in the air can be filtered to prevent them from entering the installation cavity and adhering to the electrical components. The protective mesh plate clipped at the ventilation channel can block the entry of debris, further ensuring the cleanliness of the internal environment of the distribution box body, reducing the failure of electrical components caused by dust accumulation and moisture, and improving the stability of equipment operation. (3) The smart grid distribution box with protective structure described in this invention solves the problem of low heat dissipation efficiency of traditional distribution boxes by setting active heat dissipation and passive heat dissipation methods, ensuring that the temperature of the equipment is stable during long-term continuous operation; Passive heat dissipation: The back plate is connected to the heat conduction plate on the side close to the body of the distribution box. The heat conduction plate can conduct heat in the installation cavity to the back plate. Multiple sets of parallel heat dissipation fins set on the outside of the back plate can quickly dissipate heat to the outside, realizing efficient heat conduction and dissipation; Active heat dissipation: A fan is installed on the top cover of the distribution box. A cavity is set in the top. When the fan works, it blows air into the installation cavity, causing the hot air in the installation cavity to be discharged through the ventilation slot and ventilation channel. The cold air outside enters the installation cavity through the air inlet and the cavity, forming a complete air circulation, accelerating the air flow, further improving the heat dissipation efficiency, and thus extending the service life of the equipment.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-11 As shown, the present invention discloses a distribution box with a protective structure for a smart grid, comprising a distribution box body 1, a box door 9, a concrete pouring platform 5 for assembling mounting plates 4, and a back plate 13 located on the side of the distribution box body 1 away from the box door 9. Both ends of the back plate 13 near the distribution box body 1 are vertically connected to heat-conducting plates 22, and the end of the heat-conducting plate 22 away from the back plate 13 is snapped to both ends of the distribution box body 1 through a positioning plate 32. The first protective component 8 is located at both ends of the power distribution box body 1 and is assembled on the side of the heat-conducting plate 22 away from the power distribution box body 1; The second protective component 10 is located on the side of the distribution box body 1 away from the back plate 13 and is installed on the side of the box door 9 away from the distribution box body 1. The bottom of the distribution box body 1 is fixedly connected to a base 2. The base 2 and the back plate 13 are assembled together on the mounting plate 4. The mounting plate 4 is horizontally installed on the top of the concrete pouring platform 5. Bolts are pre-embedded on the top of the concrete pouring platform 5. Through holes 25 for the pre-embedded bolts are provided at the four corners of the upper surface of the mounting plate 4. The top of the distribution box body 1 is provided with a box cover 23 for installing a fan 1206. The top of the box cover 23 is equipped with a canopy 12 for protecting the upper part of the distribution box body 1. The distribution box body 1 has an installation cavity 18 inside. The lower part of both ends of the distribution box body 1 is provided with ventilation slots 16 and ventilation channels 21 that communicate with the installation cavity 18.

[0023] Example 1 like Figure 1 , 2 As shown in 7 and 11, the present invention further includes the first protective component 8, which includes a side plate 801, a protective plate 802, a buffer layer 803, a support spring 804, and a first bolt 42. The side plate 801 and the protective plate 802 are both vertically arranged rectangular plate structures. The side plate 801 is fixedly connected to one side of the heat-conducting plate 22 by the first bolt 42. The side of the side plate 801 away from the heat-conducting plate 22 is connected to one side of the protective plate 802 by the support spring 804. The buffer layer 803 is fixedly glued to the side of the protective plate 802 away from the support spring 804. The second protective component 10 includes a vertically arranged rubber plate and support rods 11 located at the four corners of one side of the rubber plate. The end of the support rod 11 away from the rubber plate is vertically inserted into the door 9.

[0024] In this embodiment, the first protective component 8 is installed on both sides of the distribution box body 1. It forms a double buffer structure with the support spring 804 and the buffer layer 803. When the distribution box body 1 is impacted by an external force, the protective plate 802 contacts the impact force first, the support spring 804 undergoes elastic deformation to absorb most of the impact energy, and the buffer layer 803 further weakens the remaining impact force, preventing the distribution box body 1 from being directly deformed by force. At the same time, the second protective component 10 provides additional protection for the box door 9 through the rubber plate and the support rod 11. The rubber plate can resist external scratches and bumps, and the support rod 11 maintains the distance between the rubber plate and the box door 9, preventing rainwater and dust from directly contacting the box door surface and improving the corrosion resistance when used outdoors.

[0025] Example 2 like Figure 2 , 3As shown in 4, 5, 8, 9, and 10, the present invention also includes a sealing element 15 adapted to the distribution box body 1 near the box door 9. The sealing element 15 is a vertically arranged rectangular frame structure. The side of the sealing element 15 away from the distribution box body 1 is embedded into the side of the box door 9. One end of the box door 9 is rotatably connected to one side of the distribution box body 1, and the other end of the box door 9 is fixedly connected to two sets of relatively parallel pull plates 19. The lower ends of the distribution box body 1 are fitted with protective mesh plates 7 at the location of the ventilation channel 21. The ventilation channel 21 is inclined upward at the end away from the protective mesh plate 7 and communicates with the lower part of the ventilation trough 16. The bottom end of the distribution box body 1 is also provided with a second cable hole 36, and a second sealing plug 37 is fastened to the lower part of the second cable hole 36.

[0026] The present invention also includes a positioning seat 17 adapted to the pull plate 19 fixedly connected to one end of the distribution box body 1 away from the back plate 13. The pull plate 19 is fixedly connected to the positioning seat 17 by a second bolt. The two ends of the distribution box body 1 near the sealing member 15 are also provided with positioning grooves 20 adapted to the positioning plate 32. The sealing member 15 is provided with an opening communicating with the mounting cavity 18. Both ends of the power distribution box body 1 are provided with slots 24 for installing heat conduction plates 22. The slots 24 are connected to the positioning slots 20. The back plate 13 is provided with multiple sets of relatively parallel heat sinks 34 on the side away from the power distribution box body 1.

[0027] In this embodiment, the sealing element 15 is embedded between the box door 9 and the distribution box body 1 to form a closed-loop sealing structure, which effectively prevents rainwater and dust from entering the installation cavity 18. The ventilation channel 21 is set at an upward angle. After being filtered by the protective mesh plate 7, the external air enters the ventilation slot 16 and then flows into the installation cavity 18, which not only achieves air convection heat dissipation but also prevents rainwater backflow. The heat sink 34 on the back plate 13 cooperates with the heat conduction plate 22 to conduct the heat in the installation cavity 18 to the outside of the distribution box. The fan 1206 can accelerate the airflow in the installation cavity 18 and further improve the heat dissipation efficiency.

[0028] Example 3 like Figure 3 , 5 As shown, the present invention also includes a top plate 1205 for mounting a fan 1206 at the top of the mounting cavity 18, a cavity 1203 above the top plate 1205, the cavity 1203 being located inside the ceiling 12, the fan 1206 blowing air toward the mounting cavity 18, and a buckle plate 1201 fitted onto the upper part of the outer side of the cover 23 at the bottom of the ceiling 12, the buckle plate 1201 being a horizontally arranged rectangular frame structure, and an air inlet 1204 for mounting an activated carbon adsorption plate 1202 on the lower end face of the buckle plate 1201, the air inlet 1204 being connected to the cavity 1203.

[0029] In this embodiment, the fan 1206 is installed on the top plate 1205. When working, it blows air into the mounting cavity 18. The hot air in the mounting cavity 18 is discharged through the ventilation slot 16 and the ventilation channel 21. The cold air from outside enters the mounting cavity 18 through the air inlet 1204 and the cavity 1203, forming a complete air circulation. The activated carbon adsorption plate 1202 can filter dust and impurities in the air, preventing them from entering the mounting cavity 18 and adhering to the electrical components. At the same time, the roof 12 can block direct sunlight, reduce the surface temperature of the distribution box body 1, and reduce the impact of high and low temperature changes on the equipment.

[0030] Example 3 like Figure 4 , 5 As shown in Figures 6, 8, 9, and 10, the present invention further includes the following: the mounting plate 4 is a horizontally arranged rectangular plate structure; the first protective components 8 are arranged in two parallel sets; the lower part of the back plate 13 near the distribution box body 1 is provided with a protrusion 33 that engages with one side of the base 2; the lower part of the back plate 13 away from the protrusion 33 and the lower part of the base 2 away from the back plate 13 are both provided with slots 43 that are adapted to one side of the positioning component 3.

[0031] The present invention also includes that positioning members 3 are fixedly snapped onto both sides of the upper end surface of the mounting plate 4, and two sets of positioning members 3 are arranged in parallel relative to each other. One end of the two sets of positioning members 3 is connected to a baffle 27. The bottom end of the baffle 27 is fixedly connected to the upper end surface of the mounting plate 4. The two sets of positioning members 3 are provided with insertion holes 26 adapted to the insertion rod 41 at the ends away from the baffle 27. A limiting cavity 28 is provided between the two sets of positioning members 3. A locking strip 31 is fixedly connected to the center of the end of the positioning member 3 near the positioning cavity 28. A base 2 is fixed inside the limiting cavity 28. The base 2 has a cable arrangement cavity 201 inside, and the end of the base 2 away from the baffle 27 has a sealing groove 202.

[0032] The present invention also includes a groove 14 adapted to the embedded plate 40 at the center of the upper end of the mounting plate 4 away from the baffle 27, and a locking plate 6 is engaged at the end of the two sets of positioning members 3 away from the baffle 27. The locking plate 6 is vertically connected to the insertion rod 41 at both ends of the locking plate 6 at the position of the insertion hole 26, and the bottom end of the locking plate 6 is fixedly connected to one end of the upper end of the embedded plate 40 at the center. A sealing plate 35 is fixedly attached to the upper part of the locking plate 6 near the limiting cavity 28. The sealing plate 35 is located in the sealing groove 202, which is connected to the cable arrangement cavity 201.

[0033] The present invention also includes a first cable hole 29 on the upper surface of the mounting plate 4, a first sealing plug 30 in the first cable hole 29, a third cable hole 38 communicating with the cable arrangement cavity 201 located at the bottom inner wall of the first cable hole 29, and a third sealing plug 39 fastened to the top of the third cable hole 38.

[0034] In this embodiment, the mounting plate 4 is fixed to the ground by the concrete pouring platform 5, and the pre-embedded bolts pass through the through hole 25 and are threadedly connected to the locking nut to achieve a firm installation of the entire distribution box. The base 2 is snapped into the limiting cavity 28, and the positioning part 3 cooperates with the locking plate 6 to fix the base 2. The sealing plate 35 is embedded in the sealing groove 202, which can prevent water from entering the cable arrangement cavity 201. The cable enters the cable arrangement cavity 201 through the first cable hole 29 and the third cable hole 38, and then enters the mounting cavity 18 through the second cable hole 36. The sealing plugs at each cable hole can prevent rainwater and dust from entering, while avoiding cable wear and improving the stability of the cable connection.

[0035] In this smart grid distribution box with a protective structure, the cable routing channel is pre-set inside the concrete pouring platform 5. Then, the mounting plate 4 is fixed to the ground through the concrete pouring platform 5, and the base 2 is snapped into the limiting cavity 28. The base 2 is fixed by the locking plate 6 and the plug rod 41. The sealing plate 35 is embedded in the sealing groove 202 to achieve bottom sealing. The cables pre-laid in the concrete pouring platform 5 enter the cable arrangement cavity 201 through the first cable hole 29 and the third cable hole 38, and then enter the mounting cavity 18 through the second cable hole 36 to complete the cable connection. When the box door 9 is closed, the sealing element 15 is embedded between the box door 9 and the distribution box body 1 to form a closed-loop sealing structure. When the distribution box body 1 is impacted by external force, the support spring 804 and buffer layer 803 of the first protective component 8 absorb the impact force, and the rubber plate of the second protective component 10 protects the box door 9 from scratches and bumps. During operation, the fan 1206 blows air into the mounting cavity 18. The hot air in the mounting cavity 18 is discharged through the ventilation slot 16 and the ventilation channel 21. The cold air from outside enters the mounting cavity 18 through the air inlet 1204 and the cavity 1203. At the same time, the heat sink 34 and the heat conduction plate 22 on the back plate 13 assist in heat dissipation, reducing the temperature inside the mounting cavity 18 and preventing electrical components from being damaged by high temperature.
