[0028] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.

[0029] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower" are usually defined according to the direction of the drawing surface of the accompanying drawings, and "inner, outer" refer to the inside and outside of the relevant components. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present disclosure, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium. It can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0031] The lightning arrester needs to be subjected to electrical tests during production and before use to ensure that the lightning arrester meets the usage standards. Since there are no bases at both ends of the lightning arrester, a test device is required to fix the lightning arrester to facilitate the test operation. Among them, the fixing of the lightning arrester can be in a suspended form and a horizontal form. Since the lightning arrester is in a suspended form, that is, in a vertical state, in its usage environment, the suspended test is more in line with the usage scenario of the lightning arrester. Since there are no bases at both ends of the lightning arrester, if there is no test device to fix it during the test, the lightning arrester cannot maintain an upright state.

[0032] In the related art, the lightning arrester is usually tested by a temporary fixing method of hanging and hoisting. After the lightning arrester is hung and hoisted, it is prone to shaking and instability. At the same time, when the lightning arrester is replaced, the operation is very inconvenient, and it is necessary to align the hook for connection, which affects the test work efficiency. In addition, the current test fixing device has a large size, is greatly affected by the on-site environment, and there is a risk of insecure fixing. For example, in the patent No. CN110632350A, named a multifunctional bracket for facilitating tests, the lightning arrester is hung and hoisted by a hook.

[0033] As Figures 1-3 shown, the present disclosure provides a suspension type lightning arrester test device, which includes a base 1 and a locator 2.

[0034] The base 1 is connected to the bottom of the locator 2. A positioning groove 21 is formed at the top of the locator 2. The axis of the positioning groove 21 extends in the vertical direction. The positioning groove 21 is used for the bottom of the lightning arrester 5 to extend into, so that the lightning arrester 5 is vertically arranged.

[0035] In the above technical solution, through the positioning groove 21 formed at the top of the locator 2, the bottom of the lightning arrester 5 can be directly placed into the positioning groove 21. Through the limiting effect of the positioning groove 21, the lightning arrester 5 is kept in a vertical state, and the use state of the lightning arrester 5 can be simulated. Then, the provided base 1 plays a stabilizing role, so that the suspension type lightning arrester test device can be placed at the use site, and at the same time, the locator 2 and the lightning arrester 5 installed on the locator 2 can be kept stable and will not fall. The size of the present suspension type lightning arrester test device is small, does not occupy too much space, can be conveniently and quickly used on site, and at the same time, only by taking and putting down the lightning arrester 5, the rapid replacement of the lightning arrester 5 can be realized, improving the test efficiency.

[0036] In order to avoid the inconvenience of connecting the grounding wire to the lower bolt of the lightning arrester 5 after the lightning arrester 5 is vertically arranged, optionally, in an embodiment of the present disclosure, a through port 22 communicating with the positioning groove 21 is formed on the locator 2. The through port 22 is used for the grounding wire to penetrate into the positioning groove 21 and be connected to the lower bolt of the lightning arrester 5. Through the provided through port 22, the grounding wire can penetrate, so that after the lightning arrester 5 is vertically arranged, the grounding wire can be connected to the lower bolt of the lightning arrester 5 to realize the electrical test of the lightning arrester 5.

[0037] It can be understood that the through port 22 communicates with the positioning groove 21. After the lower part of the lightning arrester 5 extends into the positioning groove 21, the lower part of the lightning arrester 5 can be seen through the through port 22. Thus, the grounding wire can pass through the through port 22 and be connected to the lower bolt of the lightning arrester 5. At the same time, the size of the through port 22 can allow the grounding wire and the clamp on the grounding wire to pass through.

[0038] Optionally, in an embodiment of the present disclosure, the through port 22 is opened on the side of the locator 2 and communicates with the positioning groove 21 through the groove wall of the positioning groove 21, and the axis of the through port 22 extends in the horizontal direction. By setting it in this way, it is convenient for the grounding wire to penetrate horizontally into the positioning groove 21 to connect with the lower bolt of the lightning arrester 5, which is very convenient for operation and does not affect the vertical setting of the lightning arrester 5.

[0039] It can be understood that the through port 22 is horizontally opened, and the axis of the through port 22 is perpendicular to the axis of the positioning groove 21.

[0040] Optionally, in an embodiment of the present disclosure, the suspension type lightning arrester test device further includes a first isolation rubber pad 3, and the first isolation rubber pad 3 is connected to the through port 22 and extends along the circumference of the through port 22. By providing the first isolation rubber pad 3, it can prevent the grounding wire and the clamp from colliding with the locator 2, protect the locator 2, the grounding wire and the clamp, and can also protect the operator's hand from being scratched. At the same time, the first isolation rubber pad 3 can produce an insulating effect to avoid conductive contact between the clamp and the locator 2.

[0041] In some examples, the first isolation rubber pad 3 is located on the inner wall of the through port 22 and extends circumferentially in the through port 22 to achieve a covering effect. The first isolation rubber pad 3 can be of an annular structure. The first isolation rubber pad 3 is integrally attached to the periphery of the through port 22. A part of the first isolation rubber pad 3 can be attached to the groove wall of the positioning groove 21, and another part can be attached to the outer wall of the locator 2.

[0042] Optionally, in an embodiment of the present disclosure, the locator 2 is configured as a cylindrical structure, the cross-section of the positioning groove 21 is circular, the groove wall of the positioning groove 21 is used to contact the lower part of the lightning arrester 5, and there is a gap between the groove wall of the positioning groove 21 and the lower bolt of the lightning arrester 5. By setting it in this way, the shape of the locator 2 conforms to that of the lightning arrester 5, which can improve the positioning and fixing effect on the lightning arrester 5, prevent the lightning arrester 5 from tipping over, and ensure the test of the lightning arrester 5. By providing a gap between the groove wall of the positioning groove 21 and the lower bolt of the lightning arrester 5, it can prevent the lower bolt of the lightning arrester 5 from contacting the groove wall of the positioning groove 21.

[0043] It can be understood that after the lower part of the lightning arrester 5 extends into the positioning groove 21, the groove wall of the positioning groove 21 can contact the lower part of the lightning arrester 5 to produce a vertical limiting effect, and the lightning arrester 5 will not shake. It should be noted that the lightning arrester 5 includes a lightning arrester 5 body and a connecting bolt. In the radial direction, the size of the connecting bolt is smaller than that of the lightning arrester 5 body, and the lightning arrester 5 body includes a partial cylindrical part and a partial disc-shaped structure.

[0044] Optionally, in an embodiment of the present disclosure, in the vertical direction, the height of the locator 2 is 20 cm - 30 cm, and the depth of the positioning groove 21 is 10 cm - 15 cm. By setting like this, it can ensure the depth of the lightning arrester 5 extending into the locator 2, maintain the force on the lightning arrester 5, and thus ensure the positioning and fixing effect on the lightning arrester 5. In some examples, the height of the locator 2 is 30 cm, and the depth of the positioning groove 21 is 15 cm.

[0045] Optionally, in an embodiment of the present disclosure, the suspension type lightning arrester test device further includes a second isolation rubber pad 4. The second isolation rubber pad 4 is connected to the notch of the positioning groove 21 and part of the groove wall of the positioning groove 21, and the second isolation rubber pad 4 is used to contact the lightning arrester 5. The provided second isolation rubber pad 4 can isolate between the lightning arrester 5 and the locator 2, avoid direct contact between the lightning arrester 5 and the locator 2, protect the locator 2 and the lightning arrester 5, and at the same time, the second isolation rubber pad 4 can produce an insulating effect to avoid contact conduction between the lightning arrester 5 and the locator 2.

[0046] In some examples, the second isolation rubber pad 4 is located at the notch of the positioning groove 21 and extends along the circumference of the notch of the positioning groove 21 to achieve a covering effect. The second isolation rubber pad 4 can be of an annular structure. A part of the second isolation rubber pad 4 can be attached to the groove wall of the positioning groove 21, and another part can be attached to the outer side wall of the locator 2.
