Description

Technical Field

[0001] This utility model relates to the technical field of extended surge arrester equipment, specifically an extended surge arrester. Background Technology

[0002] Extended surge arresters are a commonly used type of surge protection device, effectively ensuring the voltage safety of electrical equipment. Utility model patent application number CN201820073417.4 discloses an extended surge arrester. A fixed block is fitted onto the outer wall of the housing, and a turntable is hinged to the side wall of the fixed block. A drive rod is hinged to the inner wall of the turntable, and one end of the drive rod is connected to a rotating rod. A movable block is arranged along the length of the insulating tube within the insulating layer. One end of the movable block is connected to a limit spring, and the other end of the movable block is hinged to a rotating rod. This utility model uses the turntable to drive the insulating layer inside the housing to move up and down, thereby... The insulating tube is moved up and down to ensure that the stress cone reaches the designated position, reducing the time spent adjusting the position of the insulating tube during installation. According to its publicly available technical solution, existing extended surge arrester equipment has two problems when in use. On the one hand, when lightning or high voltage is introduced into the ground through the conductor, the conductor is prone to rusting or even breaking due to prolonged exposure to high temperature, humidity and other environmental factors, which is not conducive to ensuring the normal operation of the extended surge arrester. On the other hand, when using the insulation mechanism to prevent leakage of the conductor, the conductor and insulation mechanism are prone to damage due to high temperature when lightning is introduced into the ground, which is not conducive to ensuring the safety of the conductor and insulation mechanism.

[0003] Therefore, how to design extended surge arresters has become a problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an extended surge arrester to solve the problems mentioned in the background art. This utility model is reasonably designed, convenient to use, and suitable for voltage protection of electrical equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extended surge arrester, comprising a surge arrester body, a conductive component installed at the bottom of the surge arrester body, the conductive component including a ground wire and a conductor, a protective component installed on the outside of the conductor, the protective component including a bushing and a drying plate, an air outlet component installed at the top of the bushing, the air outlet component including an outlet and a filter plug, an air inlet component installed at the bottom of the bushing, the air inlet component including an inlet and a partition, a waterproof component installed on the partition, the waterproof component including an air hole and a float, and a pressure relief component installed on the bushing, the pressure relief component including a conical opening and a plug.

[0006] Furthermore, the top end of the conductor is welded to the bottom of the surge arrester body, and the bottom end of the conductor is welded to the top of the ground wire. The surge arrester body is an extended type surge arrester body.

[0007] Furthermore, the top end of the bushing is welded to the bottom of the surge arrester body, the bottom end of the bushing is fitted onto the outer side of the bottom end of the conductor, and the drying plate is adhered to the inner wall of the bushing.

[0008] Furthermore, the outlet is integrally formed on one side of the top end of the sleeve, the filter plug is bonded to the inner wall of the outlet, the inlet is integrally formed on the other side of the bottom end of the sleeve, and the partition is welded to the inner wall of the inlet.

[0009] Furthermore, the air holes are opened on the inner side of the partition, the air holes are evenly distributed on the inner side of the partition, the float is disposed on the inner side of the air holes, and the inner diameter of the middle part of the air holes is larger than the diameter of the float.

[0010] Furthermore, the inner diameter of the top of the air hole is smaller than the diameter of the float, and the bottom of the float is connected to the inner wall of the bottom of the air hole by a spring.

[0011] Furthermore, the conical opening is located on the inner side of the sleeve, and the conical opening is evenly distributed around the sleeve. A through hole is provided on the inner side of the drying plate, and the conical opening is connected to the inner side of the drying plate through the through hole.

[0012] Furthermore, the outer side of the plug is engaged with the inner wall of one end of the conical opening, and the plug is connected to the inner wall of the other end of the conical opening via a second spring. The inner diameter of one end of the conical opening is larger than the inner diameter of the other end of the conical opening.

[0013] Beneficial effects: 1. When using this extended surge arrester, the top of the arrester body is connected to the power supply circuit, and the ground wire is buried underground. When the power supply circuit experiences voltage rise due to voltage instability or lightning strikes, the power is conducted to the ground through the arrester body via the conductor and ground wire, preventing high voltage from damaging electrical equipment. When the conductor conducts heat, air enters the inlet through the vent and forms a chimney effect inside the bushing. The air that absorbs the heat from the conductor is then discharged to the outside through the outlet, thus dissipating heat from the conductor. Water vapor is absorbed by the drying plate, preventing the conductor from rusting and ensuring the safety of the conductor, thereby effectively ensuring the safe operation of the arrester body.

[0014] 2. When this extended surge arrester is in use, if lightning strikes downwards into the ground through the main body of the arrester, the conductor will generate high heat, causing the air inside the bushing to expand rapidly. On the one hand, the moisture absorbed by the drying plate evaporates to cool the air, and on the other hand, the drying plate is dried. If the air pressure inside the bushing cannot be discharged outwards through the inlet and outlet in time, the air pressure will push open the stopper, which will stretch the spring and move outwards from the conical opening. The air pressure inside the bushing will then be discharged outwards through the through hole and the conical opening, ensuring the safety of the conductor and the bushing. At the same time, the bushing will prevent personnel from being electrocuted.

[0015] 3. This extended surge arrester is reasonably designed, highly efficient and convenient to use, and suitable for voltage protection of electrical equipment. Attached Figure Description

A conductive component is installed at the bottom of the surge arrester body 1. The conductive component includes a ground wire 2 and a conductor 3. A protective component is installed on the outside of the conductor 3. The protective component includes a sleeve 4 and a drying plate 5. An air outlet component is installed at the top of the sleeve 4. The air outlet component includes an outlet 6 and a filter plug 7. An air inlet component is installed at the bottom of the sleeve 4. The air inlet component includes an inlet 8 and a partition 9. A waterproof component is installed on the partition 9. The waterproof component includes an air hole 10 and a float 11. A pressure relief component is installed on the sleeve 4. The pressure relief component includes a conical opening 13 and a stopper 15. The conical opening 13 is located on the inner side of the sleeve 4 and is evenly distributed around the sleeve 4. A through hole 14 is provided on the inner side of the drying plate 5. The conical opening 13 connects to the air outlet through the through hole 14. The inner sides of the drying plate 5 are connected, and the outer side of the plug 15 is stuck on the inner wall of one end of the cone 13. The plug 15 is connected to the inner wall of the other end of the cone 13 through the second spring 16. The inner diameter of one end of the cone 13 is larger than the inner diameter of the other end of the cone 13. When lightning is introduced into the ground through the lightning arrester body 1, the conductor 3 conducts lightning and generates high heat, which causes the air in the bushing 4 to expand rapidly. On the one hand, the moisture absorbed by the drying plate 5 is evaporated to cool it down. On the other hand, the drying plate 5 is dried. When the air pressure in the bushing 4 cannot be discharged outward through the inlet 8 and outlet 6 in time, the air pressure pushes the plug 15 open. The plug 15 stretches the second spring 16 and moves outward from the cone 13. The air pressure in the bushing 4 is discharged outward through the through hole 14 and the cone 13, ensuring the safety of the conductor 3 and the bushing 4. At the same time, the bushing 4 is used to prevent personnel from being electrocuted.

[0023] In this embodiment, the top end of the conductor 3 is welded to the bottom of the surge arrester body 1, and the bottom end of the conductor 3 is welded to the top of the ground wire 2. The surge arrester body 1 is an extended type surge arrester body. The top end of the bushing 4 is welded to the bottom of the surge arrester body 1, and the bottom end of the bushing 4 is fitted onto the outer side of the bottom end of the conductor 3. The drying plate 5 is bonded to the inner wall of the bushing 4. The outlet 6 is integrally formed on one side of the top end of the bushing 4. The filter plug 7 is bonded to the inner wall of the outlet 6. The inlet 8 is integrally formed on the other side of the bottom end of the bushing 4. The partition plate 9 is welded to the inner wall of the inlet 8. The vent 10 is opened on the inner side of the partition plate 9 and is evenly distributed on the inner side of the partition plate 9. The float ball 11 is disposed on the inner side of the vent 10, and the inner diameter of the middle part of the vent 10 is larger than the diameter of the float ball 11. The inner diameter of the top of the vent 10 is smaller than the diameter of the float 11. The bottom of the float 11 is connected to the inner wall of the bottom of the vent 10 through a spring 12. In use, the top of the surge arrester body 1 is connected to the power supply circuit, and the ground wire 2 is buried underground. When the power supply circuit experiences voltage rise due to voltage instability or lightning, the surge arrester body 1 conducts the power into the ground through the conductor 3 and the ground wire 2 to prevent high voltage from damaging the electrical equipment. When the conductor 3 conducts heat, air enters the inlet 8 through the vent 10 and forms a chimney effect in the bushing 4. The air that absorbs the heat of the conductor 3 is then discharged to the outside through the outlet 6 to dissipate heat from the conductor. Water vapor is absorbed by the drying plate 5 to prevent the conductor 3 from rusting and to ensure the safety of the conductor 3, thereby effectively ensuring the safe operation of the surge arrester body 1.

[0024] In use, the top of the surge arrester body 1 is connected to the power supply circuit, and the ground wire 2 is buried underground. When the power supply circuit experiences voltage instability or is affected by lightning, causing a voltage rise, the surge arrester body 1 conducts the power into the ground through the conductor 3 and the ground wire 2, preventing high voltage from damaging electrical equipment. When the conductor 3 conducts heat, air enters the inlet 8 through the vent 10, forming a chimney effect within the bushing 4. The air absorbing the heat from the conductor 3 is then discharged out through the outlet 6, dissipating heat from the conductor. Water vapor is absorbed by the drying plate 5, preventing the conductor 3 from rusting and ensuring its safety, thus effectively protecting the surge arrester. For the safe operation of the main body 1, when lightning strikes downwards into the ground through the main body 1 of the surge arrester, the conductor 3 conducts the lightning and generates high heat, which causes the air inside the bushing 4 to expand rapidly. On the one hand, the moisture absorbed by the drying plate 5 evaporates to cool it down, and on the other hand, the drying plate 5 is dried. When the air pressure inside the bushing 4 cannot be discharged outwards through the inlet 8 and outlet 6 in time, the air pressure pushes open the stopper 15. The stopper 15 stretches the spring 16 and moves outwards from the conical opening 13. The air pressure inside the bushing 4 is discharged outwards through the through hole 14 and the conical opening 13, ensuring the safety of the conductor 3 and the bushing 4. At the same time, the bushing 4 is used to prevent personnel from being electrocuted.
