In addition, the shapes of the accessories related to strain insulators are relatively special, and usually multiple insulation blankets are required for covering, which makes it difficult to wrap the insulation blankets, and it is difficult to ensure that the wrapping is in place, posing a safety hazard.

[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0022] Utility Model

[0023] Please refer to Figure 1 A strain insulator shielding device comprises a first shielding member, a second shielding member and a tester; the first end of the first shielding member is rotatably connected to the first end of the second shielding member; the second end of the first shielding member is covered with the second end of the second shielding member, and a storage space is formed between the first shielding member and the second shielding member; the test end of the tester passes through the first shielding member or the second shielding member and is arranged in the storage space.

[0024] From the above description, it can be seen that the beneficial effects of the utility model are: by covering the first shielding member and the second shielding member to form a accommodating space, the lead wire and the related accessories of the tension insulator to be shielded can be effectively covered; and the first shielding member and the second shielding member are rotatably connected, which simplifies the covering operation compared to covering with an insulating blanket, thereby realizing rapid covering of the related accessories of the tension insulator; at the same time, a tester is also provided to detect whether the tension insulator has failed, thereby solving the problem of safety hazards caused by the failure of the tension insulator and improving operation safety.

[0025] Furthermore, the first shielding member and the second shielding member are both semi-cylindrical; the radius of the first shielding member is greater than the radius of the second shielding member, and the sum of the central angle of the first shielding member and the central angle of the second shielding member is greater than 360°.

[0026] From the above description, it can be seen that the first shielding member and the second shielding member both adopt a semi-cylindrical structure. At the same time, the radius of the first shielding member is set to be larger than the radius of the second shielding member, and the sum of the central angle of the first shielding member and the central angle of the second shielding member is larger than 360°. That is, after the first shielding member and the second shielding member are covered, part of the arc length of the first shielding member can overlap with part of the arc length of the second shielding member, thereby avoiding the situation of loose shielding.

[0027] Furthermore, the first shielding member includes an insulator shielding portion and two lead shielding portions; the lead shielding portion and the insulator shielding portion are both semi-cylindrical, and the lead shielding portion and the insulator shielding portion are coaxially arranged; the radius of the insulator shielding portion is greater than the radius of the lead shielding portion; the two lead shielding portions are respectively arranged on both sides of the insulator shielding portion along the extension direction of the cavity of the insulator shielding portion where the lead is placed.

[0028] From the above description, it can be seen that the first shielding member is divided into an insulator shielding part and a lead shielding part, and the radius of the insulator shielding part is larger than the radius of the lead shielding part, that is, the size of the insulator shielding part can adapt to the tension insulator, and the size of the lead shielding part can adapt to the lead, so that the insulator shielding part can effectively cover the tension insulator, and the lead shielding part can also cover the leads at both ends of the tension insulator, thereby improving the insulation covering effect.

[0029] Furthermore, the insulator shielding portion includes at least two sub-shielding rings; the sub-shielding rings are connected end to end in sequence along the axial direction and are arranged between the two lead shielding portions.

[0030] It can be seen from the above description that the insulator shielding portion is formed by combining multiple sub-shielding rings, and corresponding sub-shielding rings can be added according to the different numbers of insulating rings on the tension insulator, thereby achieving an effective covering effect on the tension insulator.

[0031] Furthermore, a handle is provided on a side of the first shielding member away from the second shielding member, and a handle is provided on a side of the second shielding member away from the first shielding member.

[0032] It can be seen from the above description that handles are respectively provided on the first shielding member and the second shielding member, and the handles can more conveniently perform the covering operation on the first shielding member and the second shielding member, and facilitate the grasping and use of the tension insulator shielding device.

[0033] Furthermore, it also includes a rotating member; the first rotating end of the rotating member is connected to the first end of the first shielding member; the second rotating end of the rotating member is connected to the first end of the second shielding member.

[0034] It can be seen from the above description that the first shielding member is connected to the second shielding member by using a rotating member, thereby achieving a rotatable connection between the first shielding member and the second shielding member.

[0035] Furthermore, the rotating member includes a torsion spring; two ends of the torsion spring are respectively connected to the first end of the first shielding member and the first end of the second shielding member.

[0036] From the above description, it can be seen that a torsion spring is used as a rotating part, and in the original state of the torsion spring, together with the first shielding part and the second shielding part, the first shielding part and the second shielding part are covered, so that when the first shielding part and the second shielding part are separated by an external force, the torsion spring accumulates elastic potential energy, and when the external force is released, the torsion spring can cover the first shielding part and the second shielding part again.

[0037] Furthermore, a warning light is provided on the electroscope.

[0038] It can be seen from the above description that by providing a warning light on the electroscope, live-line workers can more intuitively observe the current live state of the tension insulator.

[0039] Furthermore, a buzzer is arranged inside the electroscope.

[0040] It can be seen from the above description that by arranging a buzzer on the tester, when the tension insulator is energized, it can promptly remind the live working personnel, thereby improving the safety of the working process.

[0041] The strain insulator shielding device provided by the utility model can be applied to live power distribution operation scenes, and can effectively protect workers in the live operation process by covering the related accessories of the strain insulator. The following is an explanation through specific implementation methods:

[0042] Embodiment 1

[0043] Please refer to Figure 1 as well as Figure 4 , a strain insulator shielding device, comprising a first shielding member 1, a second shielding member 2 and a tester 3; the first end of the first shielding member 1 is rotatably connected to the first end of the second shielding member 2; the second end of the first shielding member 1 is covered with the second end of the second shielding member 2, and a storage space is formed between the first shielding member 1 and the second shielding member 2; the tester end of the tester 3 passes through the first shielding member 1 or the second shielding member 2 and is arranged in the storage space. In an optional embodiment, a warning light 5 is arranged on the tester 3, and a buzzer is arranged in the tester 3. If the insulation of the strain string fails, the warning light 5 emits red light, and if it is normal, it emits green light; since the color of the warning light 5 cannot be observed in real time during the operation, the sound and light alarm combined with the buzzer can further improve the safety of the operation process; at the same time, the position of the tester 3 can be set according to the actual position of the strain insulator.

[0044] Wherein, the first shielding member 1 and the second shielding member 2 are both semi-cylindrical and made of resin material, with an insulation withstand voltage level of 45kV / min and certain mechanical strength and hardness; due to the mechanical strength and hardness, the device has a certain limit function, further improving safety; the radius of the first shielding member 1 is greater than the radius of the second shielding member 2, and the sum of the central angle of the first shielding member 1 and the central angle of the second shielding member 2 is greater than 360°; Figure 2As shown, the first shielding member 1 is arranged at the lower part, and the second shielding member 2 is arranged at the upper part; the central angle of the second shielding member 2 is 180°, and the central angle of the first shielding member 1 is greater than 180°, that is, the arc length of the first shielding member 1 is greater than the arc length of the second shielding member 2, so that the first shielding member 1 and the second shielding member 2 will cover the opening part;

[0045] Please refer to Figure 1 and Figure 3 , the first shielding member 1 includes an insulator shielding portion 11 and two lead shielding portions 12; the lead shielding portion 12 and the insulator shielding portion 11 are both semi-cylindrical, and the lead shielding portion 12 and the insulator shielding portion 11 are coaxially arranged; wherein the coaxial arrangement means that the center of the insulator shielding portion 11 and the center of the lead shielding portion 12 are arranged on the same straight line along the extension direction of the lead, that is, the insulator shielding portion and the lead shielding portion 12 both cover the lead, and the insulator shielding portion 11 also covers the corresponding tension insulator; The radius of the insulator shielding portion 11 is greater than the radius of the lead shielding portion 12; the two lead shielding portions 12 are respectively arranged on both sides of the insulator shielding portion 11 along the extension direction of the lead; at the same time, the insulator shielding portion 11 includes at least two sub-shielding rings 111; the sub-shielding rings 111 are sequentially connected end to end along the axial direction and are arranged between the two lead shielding portions 12; the sizes of the lead shielding portion 12 and the sub-shielding rings 111 can be customized according to the commonly used sizes of distribution line tension insulators, so as to achieve full-scene coverage;

[0046] like Figure 3 As shown, the first shielding member 1 and the second shielding member 2 both include the two lead shielding portions 12 and the insulator shielding portion 11 composed of the two sub-shielding rings 111; at the same time, in order to enable the first shielding member 1 to effectively cover the second shielding member 2, the width of the sub-shielding ring 111 on the first shielding member 1 is greater than the width of the sub-shielding ring 111 on the second shielding member 2.

[0047] In an optional embodiment, a handle 6 is provided on a side of the first shielding member 1 away from the second shielding member 2 , and a handle 6 is provided on a side of the second shielding member 2 away from the first shielding member 1 .

[0048] In an optional embodiment, a rotatable connection between the first shielding member 1 and the second shielding member 2 is achieved through a rotating member 4, specifically: the first rotating end of the rotating member 4 is connected to the first end of the first shielding member 1; the second rotating end of the rotating member 4 is connected to the first end of the second shielding member 2; for example, a torsion spring is used as the rotating member 4, and the two ends of the torsion spring are respectively connected to the first end of the first shielding member 1 and the first end of the second shielding member 2; so that the torsion spring is compressed / stretched when the first shielding member 1 is separated from the second shielding member 2, and the first shielding member 1 and the second shielding member 2 are restored to cover when the torsion spring releases its elastic potential energy after letting go.

[0049] The method of using the above-mentioned tension insulator shielding device is as follows:

[0050] The tension insulator shielding device is grasped by the handle member 6, and after the position of the tension insulator to be covered is determined, the first shielding member 1 is separated from the second shielding member 2 by the handle member 6, and the second shielding member 2 is covered on the upper or lower part of the tension insulator, and then the handle member 6 on one side of the first shielding member 1 is released to reset the first shielding member 1 under the action of the rotating member 4, and cover the opening between the first shielding member 1 and the second shielding member 2; at the same time, the electroscope 3 is in contact with the tension insulator to monitor the charged condition of the tension insulator in real time.
