Description

Technical Field

[0001] This invention relates to the field of surge protector technology, specifically a surge protector with over-temperature protection. Background Technology

[0002] Surge protectors, also known as lightning arresters, surge protectors, or overvoltage protectors, are suitable for 50-60Hz circuits. They are devices that use modern electrical engineering and other technologies to prevent lightning strikes. They can be classified as switching type or voltage-limiting type. Switching type surge protectors operate on the principle of high impedance when there is no transient overvoltage, but their impedance abruptly drops to a low value in response to a lightning surge, allowing the lightning current to pass through. Therefore, in cases of excessively high temperatures, the switch automatically shuts off, protecting the circuit.

[0003] Citing Chinese utility model patent publication number "CN211266461U", this invention relates to a base, a main module, and a protective mechanism. The main module is mounted on the front surface of the base and has a protective switch installed on it. The protective mechanism is mounted on the lower surface of the base to protect the switch. The protective mechanism includes mounting blocks, a protective strip, and a clamping assembly. The mounting blocks are located on both sides of the base, and sliders are fixed to their opposite surfaces. The base has grooves along its height on both sides for the sliders to slide. The protective strip is horizontally located on the front surface of the base, and connecting rods are fixed at both ends. Clamping assemblies are installed on the connecting rods to allow the strip to be detachably mounted on the mounting blocks. This utility model, by providing a protective mechanism, allows the protective mechanism to be moved behind the switch so that when the switch is closed downwards, the switch directly impacts the protective strip, preventing damage from direct collision between the switch and the base. This indirectly increases the service life of both components and facilitates movement, ensuring that the protective strip is always behind the switch.

[0004] When existing surge protectors discharge lightning into the ground, the internal components generate a large amount of heat due to the instantaneous high current. If the heat cannot be dissipated in time, it will accumulate to the critical temperature, causing the insulation material to age, the components to be damaged, and even causing a fire. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a surge protector with over-temperature protection to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surge protector with over-temperature protection, comprising a base made of flame-retardant PC / ABS alloy, having the following characteristics: long-term operating temperature range of -40℃ to 120℃, short-term withstand temperature of 150℃, and impact resistance greater than or equal to 50kJ / m², preventing cracking during installation or disassembly; high surface resistivity to ensure electrical safety; a first surge protector module and a second surge protector module are detachably installed inside the base; an alarm is fixedly connected to the surface of the base; a ventilation and heat dissipation protection module is provided inside the base; a tripping protection module is provided inside the second surge protector module; and a third surge protector module is detachably installed inside the base, with a hydraulic over-temperature protection module inside the third surge protector module.

[0007] The ventilation and heat dissipation protection module includes a locking mechanism and a ventilation and heat dissipation mechanism;

[0008] The trip protection module includes a tripping mechanism and a heat dissipation ventilation door mechanism.

[0009] Preferably, the locking mechanism includes a first fixing block, which is fixedly connected to the bottom of the first surge protector module. A rectangular groove is provided inside the first fixing block, and a locking block is rotatably connected inside the rectangular groove. The locking block is made of spring steel, which has excellent elastic modulus and fatigue strength and can withstand repeated deformation without failure. The surface is nickel-plated to enhance corrosion resistance, making it suitable for humid or high-salt environments. The first spring has a stiffness coefficient of 30 N / mm, providing stable rebound force and ensuring that the locking block automatically resets after the pressing rod is released. A second fixing block is fixedly connected to the surface of the locking block, and a first spring is slidably connected to the surface of the second fixing block. One end of the first spring is fixedly connected to the surface of the locking block, and the other end is fixedly connected to the surface of the first fixing block. The first spring is made of piano wire, which has strong load-bearing capacity and is not easily deformed or broken, thus maintaining stable performance, reducing equipment failures caused by spring failure, and improving the reliability and service life of the surge protector. It also has good fatigue resistance, effectively resisting fatigue damage. Even after long periods and multiple operating cycles, the spring can maintain stable performance and will not weaken or break due to fatigue, ensuring the stability and reliability of the surge protector during long-term use and reducing the frequency of maintenance and replacement.

[0010] Preferably, a third fixing block is fixedly connected to the surface of the second fixing block, a fourth fixing block is rotatably connected to the interior of the third fixing block, a fifth fixing block is rotatably connected to the surface of the fourth fixing block, a pressing rod is fixedly connected to the surface of the fifth fixing block, a sixth fixing block is rotatably connected to the surface of the fifth fixing block, and a seventh fixing block is fixedly connected to the interior of the base.

[0011] Preferably, the ventilation and heat dissipation mechanism includes an eighth fixing block, which is fixedly connected to the surface of the base, and fan blades are fixedly connected inside the eighth fixing block.

[0012] Preferably, the base has a rectangular groove inside, a ninth fixing block is fixedly connected inside the base, a tenth fixing block is slidably connected to the surface of the ninth fixing block, a second spring is fixedly connected to the surface of the ninth fixing block, one end of the second spring is fixedly connected to the surface of the tenth fixing block, and the other end of the second spring is fixedly connected to the inside of the base.

[0013] Preferably, a heat-conducting sheet is fixedly connected to the surface of the tenth fixing block. The size of the heat-conducting sheet is adapted to the size of the rectangular groove opened inside the base. A magnetic block one is provided at one end of the heat-conducting sheet near the second surge protector module. A rectangular groove is opened on the surface of the first surge protector module, and a magnetic block two is provided in the rectangular groove.

[0014] Preferably, the tripping mechanism includes a first release chamber, inside which a first conductive pin is fixedly connected. A low-temperature solder layer is fixedly connected to the surface of the first conductive pin, using Sn42Bi58 eutectic solder. Sn42Bi58 has a low melting point, rapidly melting when the internal temperature of the surge protector reaches a critical value, ensuring timely circuit cutoff and avoiding the risk of fire due to overheating. Simultaneously, it falls between conventional solder and pure bismuth, ensuring stable solder joints during normal operation and rapid response in case of overheating. Sn42Bi58 is a eutectic composition, with no mushy region during melting and solidification, enabling instantaneous liquid-solid transformation. Phase transition prevents protection failure due to melting delay. A first electrical connection post is fixedly connected to the surface of the low-temperature solder layer, and a copper sheet is fixedly connected to the surface of the first electrical connection post. The copper sheet is made of T2 copper, which has high conductivity, being one of the best conductive grades of copper, enabling efficient current transmission, reducing energy loss, and ensuring the surge protector maintains low impedance characteristics when discharging lightning current. It also has high thermal conductivity, quickly transferring heat generated inside the surge protector to the heat-conducting plate, preventing localized overheating and improving heat dissipation efficiency. T2 copper is soft and easy to stamp and bend. In humid or wet environments... In a sulfur environment, a dense oxide film forms on the surface of T2 copper, significantly delaying corrosion and extending service life. A steel sheet, made of 304 stainless steel, is fixedly connected to the surface of the copper sheet. The steel sheet has an elastic modulus of 193 GPa and a yield strength greater than or equal to 205 MPa, capable of withstanding repeated bending without plastic deformation, ensuring long-term stable operation of the tripping mechanism. The 304 stainless steel contains 18% chromium and 8% nickel, exhibiting excellent corrosion resistance in humid, salt spray, or industrially polluted environments, making it suitable for outdoor or harsh working conditions. Its coefficient of thermal expansion is slightly higher than that of T2 copper, forming a significant bimetallic effect when combined with the copper sheet, reducing temperature rise. It exhibits sensitive and linear bending response; it is non-magnetic or weakly magnetic, avoiding interference with the internal electromagnetic field of the surge protector. The two ends of the steel and copper sheets are fixedly connected to the inside of the second surge protector module via a rotating shaft. The combination of steel and copper sheets offers advantages, with the bimetallic strip starting to bend at 60°C and fully tripping at 80°C, far exceeding the reliability of traditional electronic sensors. It requires no external power supply or complex circuitry, making it suitable for harsh environments such as high temperature, high humidity, and strong electromagnetic interference, thus mitigating the risk of electronic component failure. The high thermal conductivity of the copper sheet ensures rapid temperature transfer, while the elasticity of the steel sheet provides a restoring force, resulting in a response time of less than or equal to 1 second.

[0015] Preferably, an eleventh fixing block is fixedly connected to the surface of the first electrical connection post, and a twelfth fixing block is rotatably connected to the inner surface of the eleventh fixing block. There are two twelfth fixing blocks, and the two twelfth fixing blocks are symmetrically arranged about the axis of the first electrical connection post inside the second surge protector module. A thirteenth fixing block is rotatably connected to the surface of the twelfth fixing block, and the surface of the thirteenth fixing block is provided with a toothed groove.

[0016] Preferably, the heat dissipation ventilation door mechanism includes a first rotating rod, which is rotatably connected inside the second surge protector module. A second rotating rod is also rotatably connected inside the second surge protector module. A gear is fixedly connected to the surface of the second rotating rod, and the gear meshes with the first rotating rod. A damper is fixedly connected to the surface of the second rotating rod, and teeth are fixedly connected to the surface of the first rotating rod. The toothed groove on the surface of the thirteenth fixing block meshes with the teeth fixedly connected to the surface of the first rotating rod.

[0017] Preferably, the thermal expansion tripping mechanism includes a second release chamber, which is fixedly connected inside the third surge protector module. A second conductive pin is slidably connected inside the second release chamber. A second electrical connection post is fixedly connected inside the third surge protector module. A fourteenth fixing block is fixedly connected to the surface of the second conductive pin, and the fourteenth fixing block is slidably connected inside the third surge protector module.

[0018] Preferably, the third surge protector module has a first cylindrical container fixedly connected inside, a second cylindrical container fixedly connected to the surface of the first cylindrical container, a second piston rod slidably connected inside the second cylindrical container, and a first piston rod slidably connected inside the first cylindrical container, with the area of ​​the first piston rod being larger than that of the second piston rod. The third surge protector module also has a third cylindrical container fixedly connected inside, filled with perfluoropolyether oil. The thermal expansion coefficient of perfluoropolyether oil is much higher than that of ordinary oil, resulting in a more significant volume change at the same temperature rise, which can push the piston to produce a larger displacement and improve tripping sensitivity. The second piston rod is also slidably connected inside the third cylindrical container. A heat-conducting plate is fixedly connected to the surface of the third cylindrical container, and a conductive post is fixedly connected to the surface of the heat-conducting plate, with the conductive post fixedly connected inside the third surge protector module. The first and second piston rods are double-sealed to prevent liquid leakage.

[0019] This invention provides a surge protector with over-temperature protection. It offers the following advantages:

[0020] 1. This surge protector with over-temperature protection features a first fixing block at the bottom of the first surge protector module. The first surge protector module is installed from the side of the base. At this time, the block is pressed by the base and then inserted into the side groove inside the base. A pressing rod is provided. When disassembling, pressing the pressing rod causes the block to fall out of the side groove through a linkage transmission mechanism, making disassembly more convenient and adjustment easier. The structure is lightweight and compact. A seventh fixing block is provided to further restrict the sliding of the first fixing block, further improving the stability of the first surge protector module and preventing the heat dissipation path from being blocked due to shaking or displacement. This indirectly ensures the effectiveness of the over-temperature protection system and reduces the risk of overheating caused by unstable installation.

[0021] 2. This surge protector with over-temperature protection, by setting a heat-conducting plate, allows the magnetic block one on the heat-conducting plate to automatically attract the magnetic block two on the back of the first surge protector module after the first surge protector module is installed on the base. This modular design of the heat-conducting plate and the first surge protector module makes operation simple and quick. Disassembly can be done by gently separating them without tools, greatly shortening maintenance time and improving the practicality of the equipment. At the same time, the magnetic connection achieves a tight fit, which greatly improves the heat conduction efficiency. This allows the heat-conducting plate to dissipate the heat generated by the surge protector to the external environment in a timely manner, in conjunction with the rotation of the fan blades, thereby reducing the equipment temperature in time and preventing damage to the surge protector due to high temperature, ensuring the stable operation of the surge protector.

[0022] 3. This surge protector with over-temperature protection, by setting copper and steel plates, ensures that the inside of the second surge protector module is in a low-temperature state, with the copper and steel plates flat, and the surge protector operates normally. Alternatively, the inside of the second surge protector module is in a medium-temperature state, with the copper and steel plates slightly bent. Through the linkage transmission, the thirteenth fixed block drives the first rotating rod to rotate via teeth. The rotation of the first rotating rod drives multiple gears to rotate, thereby opening the damper, promoting air circulation inside the surge protector, accelerating the dissipation of heat, preventing heat accumulation inside the protector, effectively controlling the internal temperature, and preventing it from reaching the critical temperature value, ensuring that the surge protector maintains stable and reliable performance under various operating conditions.

[0023] 4. This surge protector with over-temperature protection, by setting copper and steel plates, places the inside of the second surge protector module in a high-temperature critical state. The copper and steel plates bend significantly, causing the damper to open and simultaneously promoting the separation of the first electrical connection post and the first conductive pin, thereby timely disconnecting the circuit and reducing the risk of fire or other safety accidents caused by overheating of the surge protector. This ensures the safety of personnel and equipment. Compared with the traditional method of using electronic sensors and complex circuits to drive a motor to open the damper, this method is suitable for harsh environments such as high temperature and humidity, and solves the problem of electronic component failure.

[0024] 5. This surge protector with over-temperature protection, by setting a second piston rod inside the third cylindrical container, when a large current passes through the conductive post, the high temperature generated causes the liquid medium inside the third cylindrical container to expand and compress the second piston rod through the heat-conducting plate. This ultimately pushes the end of the first piston rod to exert a thrust on the fourteenth fixing block, thus separating the second conductive pin from the second electrical connection post. This avoids the risk of fire or other safety accidents caused by overheating of the surge protector. At the same time, the area of ​​the first piston rod is larger than that of the second piston rod. Through Pascal's principle, the small force of the liquid expansion inside the third cylindrical container is ultimately exerted through the large area of ​​the first piston rod, causing it to generate a larger force, further improving the tripping sensitivity.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Examples of the 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 the invention, and should not be construed as limiting the invention.

[0045] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a surge protector with over-temperature protection, comprising a base 1, a first surge protector module 3 detachably installed inside the base 1, a second surge protector module 6 detachably installed inside the base 1, an alarm 2 fixedly connected to the surface of the base 1, a ventilation and heat dissipation protection module inside the base 1, a tripping protection module inside the second surge protector module 6, a third surge protector module 9 detachably installed inside the base 1, and a hydraulic over-temperature protection module inside the third surge protector module 9;

[0046] The ventilation and heat dissipation protection module includes a locking mechanism 4 and a ventilation and heat dissipation mechanism 5.

[0047] The locking mechanism 4 includes a first fixing block 41, which is fixedly connected to the bottom of the first surge protector module 3. A rectangular groove is provided inside the first fixing block 41. A locking block 42 is rotatably connected inside the rectangular groove of the first fixing block 41. A second fixing block 43 is fixedly connected to the surface of the locking block 42. A first spring 44 is slidably connected to the surface of the second fixing block 43. One end of the first spring 44 is fixedly connected to the surface of the locking block 42, and the other end of the first spring 44 is fixedly connected to the surface of the first fixing block 41.

[0048] The surface of the second fixing block 43 is fixedly connected to the third fixing block 45, the interior of the third fixing block 45 is rotatably connected to the fourth fixing block 46, the surface of the fourth fixing block 46 is rotatably connected to the fifth fixing block 47, the surface of the fifth fixing block 47 is fixedly connected to the pressing rod 49, the surface of the fifth fixing block 47 is rotatably connected to the sixth fixing block 48, and the interior of the base 1 is fixedly connected to the seventh fixing block 410.

[0049] The ventilation and heat dissipation mechanism 5 includes an eighth fixing block 51, which is fixedly connected to the surface of the base 1, and a fan blade 52 is fixedly connected inside the eighth fixing block 51.

[0050] A rectangular groove is provided inside the base 1. A ninth fixing block 55 is fixedly connected inside the base 1. A tenth fixing block 56 is slidably connected to the surface of the ninth fixing block 55. A second spring 54 is fixedly connected to the surface of the ninth fixing block 55. One end of the second spring 54 is fixedly connected to the surface of the tenth fixing block 56, and the other end of the second spring 54 is fixedly connected to the inside of the base 1.

[0051] A heat-conducting plate 53 is fixedly connected to the surface of the tenth fixing block 56. The size of the heat-conducting plate 53 is adapted to the size of the rectangular groove opened inside the base 1. A magnetic block 1 is provided at one end of the heat-conducting plate 53 near the second surge protector module 6. A rectangular groove is opened on the surface of the first surge protector module 3, and a magnetic block 2 is provided in the rectangular groove.

[0052] In use, the first surge protector module 3 is first installed from the side onto the surface of the base 1. At this time, the locking block 42, which is rotatably connected in the groove of the first fixing block 41, is squeezed by the base 1, so that the locking block 42 slides on the inner wall of the base 1. Then the locking block 42 is locked in the side groove of the base 1. At this time, one end face of the first fixing block 41 abuts against the seventh fixing block 410. The seventh fixing block 410 further restricts the sliding of the first fixing block 41, further improving the stability of the first surge protector module 3, avoiding the obstruction of the heat dissipation path due to shaking or displacement, thereby indirectly ensuring the effectiveness of the over-temperature protection system, reducing the risk of overheating caused by unstable installation, and realizing the installation of the first surge protector module 3.

[0053] Upon completion of installation, the magnetic block two fixedly connected to the surface of the first surge protector module 3 and the magnetic block one fixedly connected to the surface of the heat-conducting plate 53 attract each other, thereby making the heat-conducting plate 53 and the first surge protector module 3 fit tightly together, greatly improving the heat conduction efficiency. This allows the heat-conducting plate 53 to promptly dissipate the heat generated by the surge protector to the external environment in conjunction with the rotation of the fan blade 52, thereby reducing the equipment temperature in time and preventing damage to the surge protector due to high temperature, ensuring the stable operation of the surge protector. Subsequently, the fan blade 52 is activated, and the rotation of the fan blade 52 promptly dissipates the heat to the external environment, reducing the equipment temperature in time and preventing damage to the surge protector due to high temperature, thus ensuring the stable operation of the surge protector.

[0054] When the internal temperature is high, alarm 2 will sound an alarm in time. Then, the operator can press the pressing rod 49, which will cause the fifth fixing block 47 and the sixth fixing block 48 to rotate relative to each other. At the same time, the fourth fixing block 46 and the third fixing block 45 will rotate relative to each other. The pressing of the pressing rod 49 will cause the fifth fixing block 47 and the fourth fixing block 46 to rotate relative to each other, so that the third fixing block 45 and the sixth fixing block 48 will slide towards each other inside the first fixing block 41. The sliding of the third fixing block 45 and the sixth fixing block 48 will cause the two second fixing blocks 43 to slide towards each other. The sliding of the second fixing blocks 43 will cause the locking block 42 to move towards the surface of the first fixing block 41, so that the locking block 42 will disengage from the side groove opened in the base 1, thereby facilitating the timely removal of the first surge protector and preventing the surge protector from being damaged due to overheating.

[0055] By setting a first fixing block 41 at the bottom of the first surge protector module 3, the first surge protector module 3 is installed from the side of the base 1. At this time, the locking block 42 is squeezed by the base 1, and then the locking block 42 is locked into the side groove inside the base 1. A pressing rod 49 is also provided. When disassembling, pressing the pressing rod 49 causes the locking block 42 to fall out of the side groove through the linkage transmission mechanism, making disassembly more convenient, adjustment easier, and the structure lighter and more compact. A seventh fixing block 410 is also provided, which further restricts the sliding of the first fixing block 41, further improving the stability of the first surge protector module 3 and avoiding obstruction of the heat dissipation path due to shaking or displacement, thereby indirectly ensuring the effectiveness of the over-temperature protection system and reducing the risk of overheating caused by unstable installation.

[0056] By setting up the heat-conducting plate 53, when the first surge protector module 3 is installed on the base 1, the magnetic block one on the heat-conducting plate 53 and the magnetic block two on the back of the first surge protector module 3 automatically attract each other. This makes the heat-conducting plate 53 and the first surge protector module 3 modularly designed, simple and quick to operate, and easy to separate without tools, greatly shortening maintenance time and improving the practicality of the equipment. At the same time, the magnetic connection achieves a tight fit, which greatly improves the heat conduction efficiency. This allows the heat-conducting plate 53 to dissipate the heat generated by the surge protector to the external environment in a timely manner with the rotation of the fan blade 52, thereby reducing the equipment temperature and preventing damage to the surge protector due to high temperature, ensuring the stable operation of the surge protector.

[0057] Example 2: Please refer to Figure 8-14 The present invention provides a second technical solution:

[0058] The base 1 has a first surge protector module 3 detachably installed inside the base 1, and a second surge protector module 6 detachably installed inside the base 1. An alarm 2 is fixedly connected to the surface of the base 1. The base 1 has a ventilation and heat dissipation protection module inside the base 1. The second surge protector module 6 has a trip protection module inside the base 1. The base 1 has a third surge protector module 9 detachably installed inside the base 1. The third surge protector module 9 has a hydraulic over-temperature protection module inside the base 1.

[0059] The trip protection module includes a tripping mechanism 7 and a heat dissipation ventilation door mechanism 8.

[0060] The tripping mechanism 7 includes a first release chamber 72, a first conductive pin 71 is fixedly connected inside the first release chamber 72, a low-temperature solder layer 73 is fixedly connected to the surface of the first conductive pin 71, a first electrical connection post 74 is fixedly connected to the surface of the low-temperature solder layer 73, a copper sheet 78 is fixedly connected to the surface of the first electrical connection post 74, a steel sheet 79 is fixedly connected to the surface of the copper sheet 78, and the two ends of the steel sheet 79 and the copper sheet 78 are fixedly connected to the inside of the second surge protector module 6 through a rotating shaft.

[0061] An eleventh fixing block 75 is fixedly connected to the surface of the first electrical connection post 74. A twelfth fixing block 76 is rotatably connected to the inner surface of the eleventh fixing block 75. There are two twelfth fixing blocks 76, and the two twelfth fixing blocks 76 are symmetrically arranged inside the second surge protector module 6 about the axis of the first electrical connection post 74. A thirteenth fixing block 77 is rotatably connected to the surface of the twelfth fixing block 76, and the surface of the thirteenth fixing block 77 is provided with a toothed groove.

[0062] The heat dissipation ventilation door mechanism 8 includes a first rotating rod 81, which is rotatably connected inside the second surge protector module 6. A second rotating rod 85 is also rotatably connected inside the second surge protector module 6. A gear 84 is fixedly connected to the surface of the second rotating rod 85, and the gear 84 meshes with the first rotating rod 81. A damper 83 is fixedly connected to the surface of the second rotating rod 85. A tooth 82 is fixedly connected to the surface of the first rotating rod 81, and the tooth groove opened on the surface of the thirteenth fixing block 77 meshes with the tooth 82 fixedly connected to the surface of the first rotating rod 81.

[0063] When in use, if the internal temperature of the surge protector is low, the copper strip 78 and the steel strip 79 will be in a flat state, and the surge protector will work normally.

[0064] When the internal temperature of the surge protector is at a medium temperature, the copper sheet 78 and steel sheet 79 bend slightly. This slight bending causes the twelfth fixing block 76 to move towards the copper sheet 78. Simultaneously, the twelfth fixing block 76 rotates on the surface of the eleventh fixing block 75. The movement of the twelfth fixing block 76 causes the thirteenth fixing block 77 to move towards the copper sheet 78. The movement of the thirteenth fixing block 77 causes the teeth 82 fixedly connected to the surface of the first rotating rod 81 to rotate together. The rotation of the first rotating rod 81 causes the gear 84 meshing with it to rotate. The rotation of the gear 84 causes the second rotating rod 85 to rotate. The rotation of the second rotating rod 85 causes the damper 83 to rotate, thereby opening the damper 83, promoting air circulation inside the surge protector, accelerating the dissipation of heat inside the surge protector, and ensuring that the surge protector maintains stable and reliable performance under various operating conditions.

[0065] When the internal temperature of the surge protector reaches a critical high temperature, the copper sheet 78 and the steel sheet 79 bend significantly, causing the damper 83 to open. The significant bending of the copper sheet 78 and the steel sheet 79 also causes the first electrical connection post 74 to move significantly in the direction of the copper sheet 78. The movement of the first electrical connection post 74 promotes the separation of the first electrical connection post 74 from the first conductive pin 71, thereby enabling the surge protector to be in a timely power-off state, reducing the risk of fire or other safety accidents caused by overheating of the surge protector.

[0066] By setting copper sheet 78 and steel sheet 79, the inside of the second surge protector module 6 is in a low-temperature state, and the copper sheet 78 and steel sheet 79 are straight, so the surge protector works normally. The inside of the second surge protector module 6 is in a medium-temperature state, and the copper sheet 78 and steel sheet 79 are slightly bent. Through the linkage transmission, the thirteenth fixed block 77 drives the first rotating rod 81 to rotate through the teeth 82. The rotation of the first rotating rod 81 drives multiple gears 84 to rotate, thereby opening the damper 83, promoting air circulation inside the surge protector, accelerating the dissipation of heat inside the surge protector, and preventing heat from accumulating inside the protector. This effectively controls the internal temperature and prevents it from reaching the critical temperature value, ensuring that the surge protector maintains stable and reliable performance under various working conditions.

[0067] With copper sheet 78 and steel sheet 79 installed, the inside of the second surge protector module 6 is in a high-temperature critical state. The copper sheet 78 and steel sheet 79 bend significantly, which drives the damper 83 to open and simultaneously promotes the separation of the first electrical connection post 74 and the first conductive pin 71, thereby timely disconnecting the circuit and reducing the risk of fire or other safety accidents caused by overheating of the surge protector. This ensures the safety of personnel and equipment. Compared with the traditional method of opening the damper 83 by driving a motor to rotate through electronic sensors and complex circuits, this method is suitable for harsh environments such as high temperature and humidity, and solves the problem of electronic component failure.

[0068] Example 3: Please refer to Figure 15-17 The present invention provides a third technical solution:

[0069] The base 1 has a first surge protector module 3 detachably installed inside the base 1, and a second surge protector module 6 detachably installed inside the base 1. An alarm 2 is fixedly connected to the surface of the base 1. The base 1 has a ventilation and heat dissipation protection module inside the base 1. The second surge protector module 6 has a trip protection module inside the base 1. The base 1 has a third surge protector module 9 detachably installed inside the base 1. The third surge protector module 9 has a hydraulic over-temperature protection module inside the base 1.

[0070] The hydraulic over-temperature protection module includes a thermal expansion tripping mechanism 10.

[0071] The thermal expansion tripping mechanism 10 includes a second release chamber 101, which is fixedly connected to the inside of the third surge protector module 9. A second conductive pin 102 is slidably connected inside the second release chamber 101. A second electrical connection post 103 is fixedly connected inside the third surge protector module 9. A fourteenth fixing block 104 is fixedly connected to the surface of the second conductive pin 102, and the fourteenth fixing block 104 is slidably connected inside the third surge protector module 9.

[0072] The third surge protector module 9 has a first cylindrical container 106 fixedly connected inside, a second cylindrical container 107 fixedly connected to the surface of the first cylindrical container 106, a second piston rod 108 slidably connected inside the second cylindrical container 107, a first piston rod 105 slidably connected inside the first cylindrical container 106, and the area of ​​the first piston rod 105 is larger than the area of ​​the second piston rod 108. The third surge protector module 9 also has a third cylindrical container 109 fixedly connected inside, and the second piston rod 108 is also slidably connected inside the third cylindrical container 109. A heat-conducting plate 110 is fixedly connected to the surface of the third cylindrical container 109, and a conductive post 111 is fixedly connected to the surface of the heat-conducting plate 110, and the conductive post 111 is fixedly connected inside the third surge protector module 9.

[0073] In use, when the device is struck by lightning, some of the lightning passes through the conductive post 111, causing an excessive current at the conductive post 111. This causes the temperature of the conductive post 111 to rise. The increased temperature of the conductive post 111 is conducted to the third cylindrical container 109 through the heat-conducting plate 110. This causes the liquid inside the third cylindrical container 109 to expand due to heat, which in turn causes the second piston rod 108 to move. The movement of the second piston rod 108, through the second cylindrical container 107 and the first cylindrical container 106, ultimately drives the first piston rod 105 to move away from the second electrical connection post 103. This causes the first piston rod 105 to push the fourteenth fixing block 104, which in turn moves together with the second conductive pin 102, allowing the second conductive pin 102 to disconnect from the second electrical connection post 103 in a timely manner.

[0074] By setting a second piston rod 108 inside the third cylindrical container 109, when a large current passes through the conductive post 111, the high temperature generated by the current passes through the heat-conducting plate 110, causing the liquid medium inside the third cylindrical container 109 to expand and compress the second piston rod 108. This ultimately pushes the end of the first piston rod 105 to exert a thrust on the fourteenth fixing block 104, thereby separating the second conductive pin 102 from the second electrical connection post 103. This avoids the risk of fire or other safety accidents caused by overheating of the surge protector. At the same time, the area of ​​the first piston rod 105 is larger than that of the second piston rod 108. Through Pascal's principle, the small force of the liquid expansion inside the third cylindrical container 109 is ultimately exerted by the large area of ​​the first piston rod 105, causing the first piston rod 105 to generate a larger force, further improving the tripping sensitivity.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
