Description

Technical Field

[0001] This utility model relates to the field of high-voltage surge arrester technology, specifically to an earthquake-resistant high-voltage surge arrester. Background Technology

[0002] A high-voltage surge arrester is a power protection device used to protect high-voltage electrical equipment from overvoltage damage. Its core function is to rapidly conduct and discharge when an abnormal overvoltage occurs in the power grid, releasing the overvoltage energy to the ground, thereby limiting the voltage amplitude, protecting the equipment insulation from damage, and ensuring the safe and stable operation of the power system.

[0003] Traditional high-voltage surge arresters are typically installed on top of high-voltage power towers via rigid connections. However, high-voltage power towers are generally quite tall, and wind can cause lateral vibrations in the surge arrester, leading to left-right tilting. Rigid connections lack damping, causing the vibrations to directly affect the structural strength of the surge arrester, thus reducing its structural strength and affecting its normal operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-vibration high-voltage surge arrester, which has the advantages of good shock absorption and ease of use, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a seismic-resistant high-voltage surge arrester, including a base, a mounting plate fixedly mounted on the bottom of the base, a support seat fixedly mounted on the top of the base, a mounting base installed on the top of the base, a connecting rod installed in the inner cavity of the mounting base, a surge arrester body fixedly mounted on the top of the connecting rod, a lower ball head installed in the inner cavity of the support seat, a hydraulic damper fixedly mounted on the top of the lower ball head, an upper ball head fixedly mounted on the outer wall of the hydraulic damper, a fixed cylinder fixedly mounted on the top of the base, a telescopic rod movably sleeved in the inner cavity of the fixed cylinder, a drive spring movably sleeved in the inner cavity of the fixed cylinder, and a pull rod fixedly mounted on the outer wall of the telescopic rod.

[0006] As a preferred technical solution of this utility model: the outer wall shape of the lower ball head matches the inner wall shape of the support seat, and the outer wall shape of the upper ball head matches the inner wall shape of the connecting seat.

[0007] As a preferred technical solution of this utility model: the inner wall shape of the mounting base matches the outer wall shape of the connecting rod, and the hydraulic damper is a viscous damper.

[0008] As a preferred technical solution of this utility model: there are four support seats, and the four support seats are respectively installed on the top of the base.

[0009] As a preferred technical solution of this utility model: the two ends of the outer wall of the drive spring are in contact with the outer wall of the telescopic rod and the inner wall of the fixed cylinder, respectively, and the drive spring is made of high carbon steel.

[0010] As a preferred technical solution of this utility model: the outer diameter of the telescopic rod matches the inner diameter of the fixed cylinder, and the outer wall of the pull rod passes through the inner cavity of the fixed cylinder.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This earthquake-resistant high-voltage surge arrester, through the support seat set on the top of the base and the connecting seat set on the outer wall of the surge arrester body, when the surge arrester body is affected by the wind and vibrates in the left and right directions, it will cause the surge arrester body to vibrate and shift. At this time, the vibration in the left and right directions can be absorbed by the hydraulic damper, thereby reducing the amplitude of the vibration and thus avoiding damage to the structure of the surge arrester body.

[0013] 2. This seismic-resistant high-voltage surge arrester features a mounting base on the top of the base, allowing for an angular offset between the arrester body and the mounting base. This offset prevents structural damage to the arrester body caused by rigid connections. Furthermore, the installation of a fixed cylinder and a drive spring enables the telescopic rod to be driven, facilitating easy installation and removal of the mounting base.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 An anti-seismic high-voltage surge arrester includes a base 1, a mounting plate 2 fixedly mounted on the bottom of the base 1, a support seat 3 fixedly mounted on the top of the base 1, a mounting seat 4 mounted on the top of the base 1, a connecting rod 5 mounted in the inner cavity of the mounting seat 4, a surge arrester body 6 fixedly mounted on the top of the connecting rod 5, a lower ball head 7 mounted in the inner cavity of the support seat 3, a hydraulic damper 10 fixedly mounted on the top of the lower ball head 7, an upper ball head 9 fixedly mounted on the outer wall of the hydraulic damper 10, a fixed cylinder 11 fixedly mounted on the top of the base 1, a telescopic rod 12 movably sleeved in the inner cavity of the fixed cylinder 11, a drive spring 13 movably sleeved in the inner cavity of the fixed cylinder 11, and a pull rod 14 fixedly mounted on the outer wall of the telescopic rod 12.

[0022] In the above structure, the mounting plate 2 installed at the bottom of the base 1 allows the base 1 to fit better against the top of the power tower during installation. The support seat 3 installed on the top of the base 1 connects the two ends of the hydraulic damper 10 to the surge arrester body 6 and the base 1 respectively. Thus, the hydraulic damper 10 installed on the top of the base 1 limits the left and right swing amplitude of the surge arrester body 6.

[0023] In a preferred embodiment: the outer wall shape of the lower ball head 7 matches the inner wall shape of the support 3, and the outer wall shape of the upper ball head 9 matches the inner wall shape of the connecting seat 8.

[0024] In the above structure, the support seat 3 set on the top of the base 1 and the connecting seat 8 set on the outer wall of the surge arrester body 6 can play the role of installing the hydraulic damper 10 under the action of the support seat 3 and the connecting seat 8, so that the surge arrester body 6 will be absorbed and mitigated by the hydraulic damper 10 regardless of the direction of vibration that occurs during use.

[0025] In a preferred embodiment: the inner wall shape of the mounting base 4 matches the outer wall shape of the connecting rod 5, and the hydraulic damper 10 is a viscous damper;

[0026] In the above structure, the mounting seat 4 provided on the top of the base 1 and the connecting rod 5 provided on the bottom of the surge arrester body 6 enable the connecting rod 5 to be installed into the inner cavity of the mounting seat 4 when the surge arrester body 6 is installed. This allows the surge arrester body 6 to shift when vibration occurs during use on the top of the base 1, thereby avoiding damage to the overall structure of the surge arrester body 6 caused by rigid connection.

[0027] In a preferred embodiment: there are four support bases 3, and the four support bases 3 are respectively installed on the top of the base 1;

[0028] In the above structure, four support seats 3 are provided on the top of the base 1, and hydraulic dampers 10 are respectively provided between the support seats 3 and the surge arrester body 6. The vibration generated by the surge arrester body 6 is absorbed under the action of the hydraulic dampers 10, thereby avoiding damage to the overall structure of the surge arrester body 6 caused by the vibration, and thus affecting the normal use of the surge arrester body 6.

[0029] In a preferred embodiment: the two ends of the outer wall of the drive spring 13 are in contact with the outer wall of the telescopic rod 12 and the inner wall of the fixed cylinder 11, respectively, and the drive spring 13 is made of high carbon steel;

[0030] In the above structure, the drive spring 13 installed in the inner cavity of the fixed cylinder 11 can drive the telescopic rod 12 under the action of the drive spring 13, so that the telescopic rod 12 enters the inner cavity of the mounting base 4, thereby fixing the mounting base 4 under the action of the telescopic rods 12 on both sides, so that the mounting base 4 is stably installed on the top of the base 1.

[0031] In a preferred embodiment: the outer diameter of the telescopic rod 12 matches the inner diameter of the fixed cylinder 11, and the outer wall of the pull rod 14 passes through the inner cavity of the fixed cylinder 11;

[0032] In the above structure, by providing a pull rod 14 on the outer wall of the telescopic rod 12, when it is necessary to move the telescopic rod 12, by pulling the pull rod 14, the telescopic rod 12 is moved, thereby moving the telescopic rod 12 outward from the inner cavity of the mounting base 4, thereby releasing the fixation of the mounting base 4, and at this time the mounting base 4 can be replaced very conveniently.

[0033] Working principle: During use, the above equipment is installed on the top of the power tower by mounting the base 1 and connecting the two ends of the hydraulic damper 10 to the support base 3 and the connecting base 8 respectively. Then, the mounting base 4 is installed on the top of the base 1. By pulling the telescopic rod 12, the telescopic rod 12 is retracted into the inner cavity of the fixed cylinder 11, and the drive spring 13 is compressed. At this time, the mounting base 4 can be inserted into the inner cavity of the base 1. Then, the telescopic rod 12 is released, and under the action of the drive spring 13, the telescopic rod 12 enters the inner cavity of the mounting base 4, thus fixing the mounting base 4. Then, the connecting rod 5 is installed in the inner cavity of the mounting base 4. During the use of the surge arrester body 6, when the surge arrester body 6 swings in any direction, the amplitude of the vibration is limited during the contraction of the hydraulic damper 10. This prevents the surge arrester body 6 from vibrating significantly on the top of the base 1, thus avoiding structural damage caused by lateral vibration of the surge arrester body 6, which would affect the normal use of the surge arrester body 6.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
