Technical Field

[0001] The utility model relates to a lightning arrester, in particular to a separable lightning arrester. Background Art

[0002] A separable lightning arrester is a specially designed lightning arrester that allows maintenance and replacement without interrupting the power supply. This design is particularly important for facilities that require continuous power supply, as it can reduce power outage time and improve the reliability of the power system.

[0003] The separable lightning arrester needs to have environmental adaptability. Under extreme climate conditions, the performance of the separable lightning arrester may be affected. Especially in an environment with a large temperature difference or high humidity, its insulation performance may decline. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a separable lightning arrester to solve the above technical problems.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: A separable lightning arrester includes a lightning arrester, a disconnector, a lead post, a limit ring, a temperature difference resistance structure, a grounding structure, a heat dissipation ring, and a gap discharge head. The disconnector is installed at the bottom end of the lightning arrester. The lead post is installed at the top of the lightning arrester. Two limit rings are respectively fixed at the upper and lower parts of the side end of the lightning arrester. The temperature difference resistance structure is installed between the limit rings. The grounding structure is installed at the bottom side end of the lightning arrester. The heat dissipation rings are distributed at the side end of the grounding structure. The gap discharge head is installed on the grounding structure.

[0006] Based on the above technical solutions, the temperature difference resistance structure includes a shaft tube, an annular box, a connecting box, a perfusion hole, a sliding groove, a rotating groove, and a spherical wind cap. The shaft tube is installed between the upper and lower limit rings. The annular boxes are equidistantly distributed at the side end of the shaft tube. The rear end of the connecting box communicates with the side ends of all the annular boxes. The perfusion hole is arranged at the top end of the connecting box. The sliding grooves are distributed at the rear part of the side end of the connecting box and correspond to the spaces between the annular boxes. The rotating groove is arranged between the annular boxes. The spherical wind cap is rotatably connected between the annular boxes through the rotating groove.

[0007] Based on the above technical solutions, the perfusion hole fills the annular box with a heat capacity liquid through the connecting box.

[0008] Compared with the prior art, the utility model has the following advantages: By installing a temperature difference resistance structure at the side end of the separable lightning arrester, the annular box with a liquid having a high specific heat capacity absorbs the heat generated by the separable lightning arrester, and drives the spherical wind cap to rotate for heat dissipation under the internal and external temperature difference, reducing the performance degradation caused by a large temperature difference.

[0014] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] As Figures 1 to 4 shown, a separable lightning arrester includes a lightning arrester 1, a disconnector 2, a lead post 3, a limit ring 4, a temperature difference resistance structure 5, a grounding structure 6, a heat dissipation ring 7, and a gap discharge head 8. The disconnector 2 is installed at the bottom end of the lightning arrester 1, the lead post 3 is installed at the top of the lightning arrester 1, two limit rings 4 are respectively fixed at the upper and lower parts on the side of the lightning arrester 1, the temperature difference resistance structure 5 is installed between the limit rings 4, the grounding structure 6 is installed at the bottom side end of the lightning arrester 1, the heat dissipation ring 7 is distributed at the side end of the grounding structure 6, and the gap discharge head 8 is installed on the grounding structure 6.

[0016] The temperature difference resistance structure 5 includes a shaft tube 9, a ring box 10, a connecting box 11, a pouring hole 12, a slide groove 13, a rotating groove 14, and a spherical wind cap 15. The shaft tube 9 is installed between the upper and lower limit rings 4, the ring boxes 10 are equidistantly distributed on the side of the shaft tube 9, the rear end of the connecting box 11 communicates with the side ends of all the ring boxes 10, the pouring hole 12 is arranged at the top end of the connecting box 11, the slide grooves 13 are distributed at the rear part of the side of the connecting box 11 and correspond to the spaces between the ring boxes 10, the rotating groove 14 is arranged between the ring boxes 10, and the spherical wind cap 15 is rotatably connected between the ring boxes 10 through the rotating groove 14.

[0017] The pouring hole 12 pours a heat capacity liquid into the ring box 10 through the connecting box 11.

[0018] Working principle of the utility model: After the perfusion hole 12 perfuses the heat capacity liquid into the annular box 10 through the communication box 11, the perfusion hole 12 is closed. When the lightning arrester 1 operates and generates heat, the annular box 10 absorbs the dissipated heat to store the internal liquid. The heat carried by the annular box 10 is transferred to the spherical wind cap 15. The temperature difference inside and outside forces the spherical wind cap 15 to rotate for ventilation, and discharges the heat dissipated by the annular box 10. The performance degradation caused by the large temperature difference is reduced.

[0019] The above is the preferred embodiment of the utility model. For those of ordinary skill in the art, according to the teachings of the utility model, without departing from the principle and spirit of the utility model, the changes, modifications, substitutions and variations made to the implementation manners still fall within the protection scope of the utility model.
