Description

Technical Field

[0001] The utility model relates to the technical field of arrester voltage equalizing devices, in particular to a novel arrester voltage equalizing structure. Background Art

[0002] Since the high-voltage lightning arrester has stray capacitance to the ground, the voltage distribution along the lightning arrester is uneven, so the places with high voltage are prone to damage. Therefore, a lightning arrester voltage equalizing ring is added to balance the stray capacitance to the ground, so that the voltage distribution is uniform and no local breakdown and damage occurs. The higher the voltage level, the greater the stray capacitance to the ground.

[0003] The existing arrester voltage-equalizing ring and bracket are welded in the factory to form a whole, and then transported to the required installation location. Since the voltage-equalizing ring and bracket are welded together, the volume will be very large, which is not convenient for transportation and installation on the arrester. Summary of the invention

[0010] As a preferred technical solution of the utility model, a fixing hoop 1 is fixedly assembled on one end of the support rod away from the connecting plate, and a fixing hoop 2 is movably connected to the outer edge of the bottom of the fixing hoop 1.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 - Figure 6 A novel voltage-equalizing structure of a lightning arrester comprises a lightning arrester body 1, the inner cavity of the lightning arrester body 1 is provided with a double-headed screw 2, a limiting groove 3 is provided on the top of the lightning arrester body 1, the inner wall of the limiting groove 3 is provided with a quick-release component 4, the inner cavity of the quick-release component 4 is clamped with a voltage-equalizing ring structure 5, and the quick-release component 4 is fixed to the lightning arrester body 1 through a nut 21. By arranging the quick-release component 4 on the lightning arrester body 1 and installing the voltage-equalizing ring structure 5 in the quick-release component 4, the quick-release component 4 can realize the quick-release and quick-disassembly function of the voltage-equalizing ring structure 5, thereby greatly improving the installation time and maintenance time of the voltage-equalizing ring structure 5.

[0023] In a preferred embodiment, the quick-release assembly 4 includes a bottom connecting frame 401, the inner wall of the bottom connecting frame 401 is fixedly equipped with a protrusion 402, the bottom of the protrusion 402 is fixedly equipped with a limiting rod 403, and the tops of the bottom connecting frame 401 and the protrusion 402 are both provided with vertical holes 404. By inserting the limiting rod 403 into the limiting groove 3, the bottom connecting frame 401 cannot rotate. The cooperation of the limiting rod 403 and the limiting groove 3 prevents the bottom connecting frame 401 from rotating, thereby improving the stability of the device.

[0024] In a preferred embodiment, a top connecting frame 405 is fixedly installed on the top of the bottom connecting frame 401, a circular hole 406 is opened at the bottom of the top connecting frame 405, and an anti-slip component 408 is slidably connected to the inner wall of the circular hole 406. The anti-slip component 408 is slidably connected to the inner wall of the top connecting frame 405, and both ends of the anti-slip component 408 are fixedly installed with a lever 409. By lifting the lever 409 upward, the lever 409 can drive the anti-slip component 408 to move in the top connecting frame 405, so that the anti-slip component 408 can be detached from the vertical hole 404 and the slot 503. At this time, the equalizing ring structure 5 can be taken down as a whole, thereby improving the quick release speed of the device.

[0025] In a preferred embodiment, a support spring 410 is provided at the top of the anti-slip component 408, and the top of the support spring 410 contacts the top of the inner cavity of the top connecting frame 405. A slide groove 407 is provided on the outer wall of the top connecting frame 405, and the lever 409 is slidably connected to the slide groove 407. Through the setting of the support spring 410, the support spring 410 supports the anti-slip component 408, so that the anti-slip component 408 is stably in the vertical hole 404 in a static state, so that the connecting plate 501 will not fall off, thereby improving the stability of the device.

Connecting blocks 504 are provided at both ends of the connecting plate 501, and the inner wall of the connecting block 504 is movably connected to a support rod 505. The support rod 505 is movably connected to the connecting plate 501, so that the angle between the support rod 505 and the connecting plate 501 can be changed, so that a straight line can be formed between the support rod 505 and the connecting plate 501, so that the device is easy to transport and occupies little space.

[0027] In a preferred embodiment, a fixing hoop 506 is fixedly assembled at one end of the support rod 505 away from the connecting plate 501, and a fixing hoop 507 is movably connected to the outer edge of the bottom of the fixing hoop 506. The fixing hoop 507 is fixed to the support rod 505 by a bolt 508. A pressure equalizing ring body 509 is provided in the inner cavity of the fixing hoop 506 and the fixing hoop 507. When disassembling, the fixing hoop 507 is separated from the fixing hoop 1 506 by unscrewing the bolt 508. At this time, the pressure equalizing ring body 509 can be removed, so that the pressure equalizing ring body 509, the support rod 505 and the connecting plate 501 can be stored separately, thereby reducing space occupancy.

[0028] Working principle: when in use, by lifting the lever 409 upwards, the lever 409 drives the anti-slip component 408 to rise in the top connecting frame 405, and the anti-slip component 408 disengages from the vertical hole 404. At this time, the support spring 410 is compressed, and then the connecting plate 501 is inserted into the gap between the bottom connecting frame 401 and the top connecting frame 405, and then the force is unloaded on the lever 409, and the anti-slip component 408 is pushed downward by the elastic force of the support spring 410. At this time, the anti-slip component 408 passes through the slot 503 on the connecting plate 501 to reach the vertical hole 404. At this time, the connecting plate 501 is fixed, and then the equalizing ring body 509 is placed on the fixing hoop 1 506, and then the fixing hoop 2 507 is merged with the fixing hoop 1 506, and then the fixing hoop 2 507 is fixed to the support rod 505 by the bolt 508. At this time, the installation is completed.
