Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to a buckle-type live-loaded and detachable lightning arrester device with a protective gap. Background Art

[0002] A lightning arrester, also known as an overvoltage protector, is an electrical device used to protect electrical equipment from high transient overvoltage hazards and limit the follow-on time and often the follow-on value.

[0003] When in use, the lightning arrester is installed near the protected equipment and connected in parallel with the protected equipment. Under normal circumstances, the lightning arrester is not conductive (only a leakage current of microamperes flows at most). When the voltage acting on the lightning arrester reaches the operating voltage of the lightning arrester, the lightning arrester is turned on, passing a large current, releasing the overvoltage energy and limiting the overvoltage to a certain level to protect the insulation of the equipment. After releasing the overvoltage energy, the lightning arrester returns to its original state.

[0004] When installing a lightning arrester, the existing technology cannot complete live loading and unloading under high voltage. During installation, it can only be fixed on the pole manually during a power outage. If it needs to be replaced after deterioration, the power must be turned off first, and the arrester must be manually disassembled and replaced on the pole, which is labor-intensive and time-consuming and cannot guarantee the continuity of power supply.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1-Figure 4 As shown, this embodiment provides a buckle-type live-loading and detachable lightning arrester device with a protective gap, including a mold frame 1, a groove is opened on the mold frame 1, an upper mold 2 is installed on the top of the groove, a lower mold 3 is provided below the upper mold 2, the lower mold 3 is slidably connected to the mold frame 1, a sliding assembly is installed in the mold frame 1, the sliding assembly is fixed to the lower mold 3, the bottom surface of the mold frame 1 is threadedly connected to the lightning arrester 5, the side wall of the mold frame 1 is fixed to an operating block 6, and the operating block 6 is detachably connected to the insulating rod 4.

[0022] The lightning arrester 5 is an integrated lightning arrester 5 with a protective gap, and the insulating rod 4 is made of glass fiber reinforced plastic epoxy resin. When in use, the insulating rod 4 is clamped in the operating block 6, and the insulating rod 4 is held to lift the lightning arrester 5 and the mold frame 1 so that the lower mold 3 contacts the bare wire. The upper mold 2 and the lower mold 3 are both provided with jaws, and the jaws are adapted to the bare wire. The bare wire is clamped at the jaws of the lower mold 3. At this time, the insulating rod 4 is pushed upward so that the bare wire squeezes the lower mold 3. The lower mold 3 moves into the mold frame 1 and releases the limit at the same time. The lower mold 3 is lifted by the sliding assembly so that the lower mold 3 contacts the upper mold 2, and the bare wire is clamped in the two jaws to complete the installation. A spring extrusion structure (not shown) is installed in the top of the mold frame 1. The spring extrusion structure is connected to the upper mold 2, thereby ensuring that the upper mold 2 and the lower mold 3 clamp the bare wire. The utility model can complete the installation of the lightning arrester 5 under live conditions without power outages, saving time and effort and ensuring the continuity of power supply.

[0023] A further optimization scheme includes a symmetrically arranged connecting block 13, which is fixedly connected to the lower mold 3. One end of a lifting spring 14 is fixedly connected to the bottom of the connecting block 13, and the other end of the lifting spring 14 is fixedly connected to the inner bottom surface of the mold frame 1. A clamping rod 17 is slidably connected to the connecting block 13, and the clamping rod 17 contacts the clamping assembly, which is fixedly connected to the inner bottom surface of the mold frame 1. When not in use, the clamping rod 17 contacts the clamping assembly, and the upper mold 2 and lower mold 3 do not contact. When in use, the clamping rod 17 and the clamping assembly are released from the restraint, and the lifting spring 14 lifts the lower mold 3, so that the upper mold 2 and lower mold 3 contact and clamp the bare wire.

[0024] A further optimized solution is provided, in which the clamping assembly includes a fixing rod 15 fixed to the inner bottom surface of the mold frame 1. A first protrusion 16 is fixed to the fixing rod 15, and a second protrusion 19 is provided above the first protrusion 16. The second protrusion 19 is fixed to the top surface of the fixing rod 15. The first protrusion 16 and the second protrusion 19 are respectively detachably connected to the clamping rod 17. When not in use, the clamping rod 17 contacts the bottom of the second protrusion 19. When in use, the lower mold 3 moves downward, driving the clamping rod 17 downward. When the clamping rod 17 contacts the first protrusion 16, it retracts. At this time, the clamping rod 17 rebounds to the top of the second protrusion 19 under the force of the lifting spring 14, releasing the restriction and completing the clamping of the bare wire.

[0025] In a further optimized solution, a return spring 18 is sleeved on the outside of the clamping rod 17. An annular plate is fixed to the outside of the clamping rod 17. One end of the return spring 18 is fixed to the annular plate, and the other end of the return spring 18 is fixed to the connecting block 13. The provision of the return spring 18 facilitates the reuse of the clamping rod 17 and facilitates the control of the contact state between the lower mold 3 and the upper mold 2.

[0026] In a further optimized solution, slide rails 11 are symmetrically fixed to the mold frame 1, and sliders 12 are slidably connected to the slide rails 11. The side walls of the sliders 12 are fixed to the connecting blocks 13. The sliders 12 slide on the slide rails 11, and the connecting blocks 13 are fixedly connected to the sliders 12, thereby ensuring smooth and stable sliding of the lower mold 3.

[0027] To further optimize the solution, the operating block 6 is provided with a through hole, which is adapted to the insulating rod 4. The operating block 6 is provided with a through slot 7, which is connected to the through hole, which is connected to a connecting slot 8, which is connected to a clamping slot 9. A clamping block 10 is fixed to the insulating rod 4, which is adapted to the through slot 7, the connecting slot 8 and the clamping slot 9 respectively. Insert the top of the insulating rod 4 into the through hole, at which time the clamping block 10 is located in the through slot 7, then rotate the insulating rod 4 so that the clamping block 10 is screwed into the connecting slot 8, and then push the insulating rod 4 upward so that the clamping block 10 is clamped into the clamping slot 9. At this time, lifting the insulating rod 4 can lift the mold frame 1 and the lightning arrester 5 together; the reverse operation can be performed for disassembly.

[0028] Overall working principle:

[0029] Hanging: Specifically, the arrester 5 assembly with (external series) discharge gap is installed on the mold frame 1 (via threaded connection), and the upper and lower jaws are in the open state. The head end of the insulating rod 4 is inserted into the through hole of the operating block 6 and rotated 90 degrees. The insulating rod 4 is fixed, and then the entire device is hung on the bare wire with the insulating rod 4, and the jaws of the upper mold 2 are in contact with the bare cable to complete the hanging operation of the device.

[0030] Locking operation process:

[0031] Push the insulating rod 4 upward, so that the jaws of the lower die 3 come into contact with the bare wire and generate a downward squeezing force on the lower die 3, driving the lower die 3 to move downward. The clamping rod 17 moves downward and contacts the first protrusion 16 and then contracts back. Then, the upward pushing force is released. Under the action of the lifting spring 14, the clamping rod 17 moves upward to above the second protrusion 19, driving the lower die 3 to contact the upper die 2, completing the locking. The insulating rod 4 is removed, completing the automatic clamping of the bare wire, and realizing the live installation.

[0032] Extraction process:

[0033] Insert the head end of the insulating rod 4 into the through hole and rotate it 90 degrees to lock the insulating rod 4 and fix the insulating rod 4. Then push up the insulating rod 4 to move the lower mold 3 downward, driving the clamping rod 17 to move downward. The clamping rod 17 contacts the second protrusion 19 and contracts. When it moves below the second protrusion 19, it is reset under the action of the reset spring 18, so that the top of the clamping rod 17 contacts the bottom of the second protrusion 19 to complete the clamping. At this time, the upper mold 2 and the lower mold 3 are not in contact. Then use the insulating rod 4 to remove the entire device to complete the removal operation.
