[0002] A surge arrester is an electrical device used to protect electrical equipment from high transient overvoltages and to limit the duration and magnitude of follow current. This term includes any external clearance necessary for the normal functioning of the device during operation and installation, whether or not it is a component of the whole.
[0003] The inventors discovered during routine use of surge arresters that, since surge arresters designed to resist interference are usually made of metal, prolonged exposure to wind and rain can cause the metal surge arresters to corrode, affecting their effectiveness and causing problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lightning protection device with anti-interference capabilities.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightning protection device with anti-interference capability, comprising a lightning arrester, wherein a protective device is provided on the surface of the lightning arrester, and connecting columns are fixedly connected to the upper and lower ends of the lightning arrester, and splicing devices are provided on the surface of the connecting columns. The protective device includes a protective cover provided on the surface of the lightning arrester, wherein a slot is provided on the side of the protective cover, and a protrusion is fixedly connected to the surface of another protective cover, and a retaining ring is fixedly connected to the surface of the protrusion.
[0006] The aforementioned components achieve the following effects: the protective cover prevents the surge arrester from being exposed to wind and rain, thus avoiding corrosion. Since the protective cover is made of PVC, it also provides anti-interference protection. When the surge arrester is needed, it is connected to electronic equipment or a substation for lightning protection. Because the surge arrester is made of zinc oxide, it also provides anti-interference protection, thus making it an anti-interference surge arrester.
[0007] Preferably, a baffle is fixedly connected to the surface of the surge arrester, and the baffle is disposed at the upper and lower ends of the surge arrester.
[0008] The effect achieved by the above components is that, under the action of the baffle, the respective components will not move on the surface of the surge arrester, thereby achieving the protective function.
[0009] Preferably, a locking rod is inserted into the surface of the protective cover, and the locking rod is inserted into the interior of the protrusion.
[0010] The effect achieved by the above components is that, under the action of the clamp, the protective covers can be fixed together after being spliced, thus preventing the protective covers from separating.
[0011] Preferably, a spring is fitted onto the surface of the clamp rod, and the two ends of the spring are fixedly connected to one end of the clamp rod at the top of the protective cover.
[0012] The aforementioned components achieve the following effects: Under the action of the spring, the locking rod is inserted into the protrusion in a self-locking manner, thereby achieving a fixing effect. When the surge arrester needs protection, the protective cover is moved relative to it, and the protrusion is inserted into the slot. Under the action of the retaining ring, the protrusion can be locked inside the slot. When assembling the protective cover, the baffle is placed inside the protective cover, thus preventing the protective cover from shifting and protecting the surge arrester. After the protrusion is fully inserted into the slot, under the action of the spring, the locking rod is inserted into the protrusion in a self-locking manner, thereby achieving a fixing effect and thus achieving the protection effect.
[0013] Preferably, the splicing device includes a threaded groove formed on the surface of the connecting column, a groove formed at the bottom of the connecting column, a T-shaped block rotatably connected inside the groove, a connecting frame fixedly connected to one end of the T-shaped block, and a threaded connection inside the connecting frame.
[0014] The effect achieved by the above components is that the threads and grooves inside the connecting frame allow the surge arresters to be spliced together, and the T-block allows the connecting frame to rotate at the bottom of the connecting column, thus facilitating the connection of the surge arresters.
[0015] Preferably, the surface of the connecting column is provided with a through groove, the surface of the connecting frame is provided with a through groove, a bolt is inserted into the through groove, and one end of the bolt is threaded with a nut.
[0016] The effect achieved by the above components is that, under the action of bolts and nuts, the connecting column will not slip out of the inside of the connecting frame, thereby achieving the function of fixing.
[0017] Preferably, a washer, which is a rubber pad, is fitted onto the surface of the bolt.
[0018] The effect achieved by the above components is that, with the action of the washer, the nut will not overload the bolt.
[0019] Preferably, a pad is fixedly connected to the top of the connecting column, and a pad is fixedly connected to the inside of the connecting frame.
[0020] The aforementioned components achieve the following effects: The pads prevent misalignment of the through slots when connecting the connecting post to the connecting frame. When splicing surge arresters, one end of the connecting post is inserted into the connecting frame. The screw groove and threads tighten the connecting post into the connecting frame. The T-block allows the connecting frame to rotate within the connecting post, facilitating connection. After the connecting post is screwed into the connecting frame, the pads prevent misalignment of the through slots. Once aligned, bolts are inserted into the through slots, and nuts are tightened onto the other end of the bolts, fixing the connecting post inside the connecting frame. The washers prevent overloading of the bolts with the nuts, thus achieving the splicing effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up a protective device, when the surge arrester needs protection, the protective cover is moved relative to the surge arrester, and the protrusion is inserted into the slot. Under the action of the retaining ring, the protrusion can be locked inside the slot. When assembling the protective cover, the baffle is placed inside the protective cover, so that the protective cover will not shift, thus protecting the surge arrester. After the protrusion is fully inserted into the slot, under the action of the spring, the retaining rod is self-locking and inserted into the protrusion, thus achieving the fixing function and the protection function. This solves the problem that metal anti-interference surge arresters will corrode and weaken their lightning protection effect due to prolonged exposure to rain. Attached Figure Description

The surface of the surge arrester 1 is provided with a protective device 2. The upper and lower ends of the surge arrester 1 are fixedly connected to connecting posts 4. The surface of the connecting posts 4 is provided with a splicing device 3. When the surge arrester 1 is needed, it is connected to electronic equipment or a substation to provide lightning protection for the electronic equipment or substation. Since the surge arrester 1 is made of zinc oxide, it achieves the function of anti-interference, thus making the surge arrester 1 an anti-interference surge arrester.
[0029] Reference Figure 2 The protective device 2 includes a protective cover 21 installed on the surface of the surge arrester 1. A slot 24 is provided on the side of the protective cover 21. A protrusion 22 is fixedly connected to the surface of another protective cover 21, and a retaining ring 23 is fixedly connected to the surface of the protrusion 22. Under the action of the protective cover 21, the surge arrester 1 is protected from wind and rain, thus preventing corrosion. Since the protective cover is made of PVC, it also provides anti-interference. When the surge arrester 1 needs to be used, it is connected to electronic equipment or a substation. Inside the station, lightning protection is provided for electronic equipment or substations. Since the surge arrester 1 is made of zinc oxide, it achieves anti-interference capabilities, thus becoming an anti-interference surge arrester 1. A baffle 25 is fixedly connected to the surface of the surge arrester 1, positioned at the upper and lower ends. Under the action of the baffle 25, the respective guards 21 will not move on the surface of the surge arrester 1, thereby achieving a protective function. A locking rod 26 is inserted into the surface of the protective cover 21, with the locking rod 26 having a protruding... Inside block 22, under the action of latch 26, the protective cover 21 can be fixed together after being spliced, preventing the protective cover 21 from separating. A spring 27 is fitted onto the surface of latch 26, with both ends of the spring 27 fixedly connected to one end of latch 26 at the top of the protective cover 21. Under the action of the spring 27, the latch 26 self-locks into the interior of protrusion 22, thus achieving a fixing effect. When protection for surge arrester 1 is required, the protective cover 21 is moved relative to the protrusion 22. The block 22 is inserted into the slot 24. Under the action of the retaining ring 23, the protrusion 22 can be locked inside the slot 24. When splicing the protective cover 21, the baffle 25 is placed inside the protective cover 21, so that the protective cover 21 will not shift, thus protecting the surge arrester 1. After the protrusion 22 is fully inserted into the slot 24, under the action of the spring 27, the locking rod 26 is inserted into the protrusion 22 in a self-locking manner, thus achieving the fixing function and the protection function.
[0030] Reference Figure 3-4The splicing device 3 includes a threaded groove on the surface of the connecting column 4, a groove at the bottom of the connecting column 4, and a T-shaped block 36 rotatably connected inside the groove. One end of the T-shaped block 36 is fixedly connected to a connecting frame 32. The connecting frame 32 has threads inside. Under the action of the threads and the threaded groove inside the connecting frame 32, the surge arresters 1 can be spliced together. Under the action of the T-shaped block 36, the connecting frame 32 can rotate at the bottom of the connecting column 4, thus facilitating the connection of the surge arresters 1. A through groove 31 is opened on the surface of the connecting column 4, and a through groove 31 is opened on the surface of the connecting frame 32. A bolt 33 is inserted inside the through groove 31, and a nut 34 is threadedly connected to one end of the bolt 33. Under the action of the bolt 33 and the nut 34, the connecting column 4 will not slip out of the connecting frame 32, thus achieving a fixing effect. A washer 35 is fitted on the surface of the bolt 33. The washer 35 is a rubber pad. Under the action of the washer 35, the nut 34 will not overtighten the bolt 33. For example, a pad 37 is fixedly connected to the top of the connecting column 4, and a pad 37 is fixedly connected inside the connecting frame 32. Under the action of the pad 37, the connecting column 4 will not misalign with the through groove 31 when connected to the connecting frame 32. When it is necessary to splice the surge arrester 1, one end of the connecting column 4 is inserted into the inside of the connecting frame 32. Under the action of the screw groove and the thread, the connecting column 4 is tightened into the inside of the connecting frame 32. Under the action of the T-block 36, the connecting frame 32 can rotate inside the connecting column 4, which facilitates the connection. After the connecting column 4 is screwed into the inside of the connecting frame 32, the through groove 31 will not misalign under the action of the pad 37. After the through groove 31 is aligned, the bolt 33 is inserted into the inside of the through groove 31, and the nut 34 is screwed onto the other end of the bolt 33, thereby fixing the connecting column 4 inside the connecting frame 32. Under the action of the washer 35, the nut 34 will not overload the bolt 33, thus achieving the splicing function.
[0031] Working principle: When an anti-interference lightning protection device is required, surge arrester 1 is connected to the electronic equipment or substation to provide lightning protection. Since surge arrester 1 is made of zinc oxide, it achieves anti-interference capabilities, thus becoming an anti-interference surge arrester. When protection is needed for surge arrester 1, the protective cover 21 is moved relative to the device, and the protrusion 22 is inserted into the slot 24. Under the action of the retaining ring 23, the protrusion 22 can be secured inside the slot 24. When assembling the protective cover 21, the baffle 25 is placed inside the protective cover 21 to prevent displacement, thus protecting the surge arrester 1. After the protrusion 22 is fully inserted into the slot 24, the spring 27 causes the locking rod 26 to... The self-locking mechanism is inserted into the protrusion 22, thus achieving a fixing function and a protective function. When it is necessary to splice the surge arrester 1, one end of the connecting post 4 is inserted into the connecting frame 32. Under the action of the screw groove and thread, the connecting post 4 is tightened into the connecting frame 32. Under the action of the T-block 36, the connecting frame 32 can rotate inside the connecting post 4, thus facilitating the connection. After the connecting post 4 is screwed into the connecting frame 32, the pad 37 ensures that the through groove 31 will not be misaligned. After the through groove 31 is aligned, the bolt 33 is inserted into the through groove 31, and the nut 34 is screwed onto the other end of the bolt 33, thus fixing the connecting post 4 inside the connecting frame 32. Under the action of the washer 35, the nut 34 will not overload the bolt 33, thus achieving the splicing function.
