Conventional pre-testing requires a round of live lightning arrester testing of zinc oxide lightning arresters before the start of the thunderstorm season every year. Since the structure of some open lightning arresters is about 2-3 meters above the ground, it is usually necessary to use a relay stool or ladder to manually short-circuit the leakage current meter at the bottom of the lightning arrester. Generally, there are more than 30 groups of lightning arresters in a 220kV substation, each with 3-phase lightning arresters.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-2 The figure shows the first embodiment of the grinding and clamping device for the ammeter connector of the outdoor lightning arrester according to the present invention.

[0021] The grinding and clamping device for the ammeter connector of the outdoor lightning arrester in this embodiment comprises: an insulating telescopic rod 1, the insulating telescopic rod 1 comprises: a rotatable metal threaded tube 11; A grinding clamping assembly 2 detachably connected to the end of the insulating telescopic rod 1, the grinding clamping assembly 2 comprising: an adjusting arm 21 fastened to the end of the insulating telescopic rod 1, a threaded transmission member 22 mounted on the adjusting arm 21, a first wire clamp meshed with the threaded transmission member 22, and a second wire clamp meshed with the threaded transmission member 22; The first wire clamp and the second wire clamp are respectively mounted on the adjusting arm 21 , and the two wire clamps are arranged adjacent to each other. The threaded transmission member 22 is in transmission connection with the metal threaded pipe 11 .

[0022] Wherein: the metal threaded tube 11 links the threaded transmission member 22 to rotate relative to the adjusting arm 21, and the threaded transmission member 22 drives the first wire clamp to clamp the ammeter connector and grind it, or drives the second wire clamp to clamp the test line of the lightning arrester tester.

[0023] In the specific implementation, the insulating telescopic rod 1 is a multi-section structure that can be telescopic, and the multi-section insulating telescopic rod is locked by a spiral lock. The insulating telescopic rod 1 includes a rotatable metal threaded tube 11, and the metal threaded tube 11 is provided with a rotating gear 111.

[0024] In this embodiment, the insulating telescopic rod 1 can be up to 15 meters long, and the retracted length is less than 0.7 meters, so as to adapt to the height of the common open-type lightning arrester leakage current meter on site, and at the same time, it is easy to carry and transport. During implementation, the insulating telescopic rod 1 can be freely retracted according to the height of the lightning arrester leakage current meter on site, and each section of the insulating rod can be locked at any extended length, so that the on-site operators can freely adjust the total height of the lifting rod.

[0025] The grinding and clamping assembly 2 has the function of biting the leakage current meter joint, grinding the connection head and clamping the test line of the arrester tester. The grinding and clamping assembly 2 includes an adjustment arm 21, a threaded transmission member 22, a first wire clamp and a second wire clamp.

[0026] The adjusting arm 21 is a bracket structure, which is fastened to the end of the insulating telescopic rod 1. The function of the adjusting arm 21 is to provide support for the components of the grinding clamping assembly 2. In specific implementation, the adjusting arm 21 adopts a detachable design that can freely adjust the length and rotation angle, so that the adjusting arm 21 can be freely adjusted according to the different lateral dimensions and rotation angles of the on-site tested equipment so that the clamping device is fixed in a suitable position to fit the tested equipment closely.

[0027] Furthermore, the threaded transmission member 22 includes: a threaded transmission rod 221 and a steering gear 222 fastened to the threaded transmission rod 221, and the steering gear 222 is meshed and connected with the rotating gear 111 on the metal threaded tube 11. During implementation, the metal threaded tube 11 sequentially drives the rotating gear 111 and the steering gear 222 to make the threaded transmission rod 221 rotate relative to the adjusting arm 21.

[0028] The first wire clamp is meshed and connected with the threaded transmission member 22 , and is installed on the adjustment arm 21 . The function of the first wire clamp is to clamp the ammeter connector and grind it under the drive of the threaded transmission member 22 .

[0029] In this embodiment, the first wire clamp includes: a first bidirectional screw rod 31 meshingly connected to the steering gear 222 and a first wire clamp body 32 that can move bidirectionally reciprocatingly along the first bidirectional screw rod 31. The first wire clamp body 32 is a clamping structure that can clamp the ammeter connector and grind it.

[0030] Preferably, the first wire clamp body 32 of the present embodiment has a built-in vibration motor, and a file is installed on the surface of the first wire clamp body 32 to grind away the rust on the ammeter joint clamped by the first wire clamp body 32 .

[0031] Preferably, the first wire clamp body 32 is made of wear-resistant material to reduce wear during the process of grinding rust at the joint and increase the service life of the product.

[0032] Furthermore, the second wire clamp is meshed with the threaded transmission member 22 and is mounted on the adjustment arm 21. The second wire clamp includes a second bidirectional screw rod 41 meshed with the steering gear 222 and a second wire clamp body 42 capable of bidirectional reciprocating movement along the second bidirectional screw rod 41.

[0033] Preferably, the second wire clamp body 42 is also provided with a conductor coating for connecting a test line of a lightning arrester tester.

[0034] The function of the second wire clamp is to clamp the test wire of the lightning arrester tester under the drive of the threaded transmission member 22 to achieve reliable short-circuiting of the leakage current meter connector.

[0035] In this embodiment, the first wire clamp and the second wire clamp are arranged adjacent to each other. The effect of such arrangement is that the threaded transmission member 22 can be kept in mesh with the two wire clamps at the same time, thereby realizing linkage.

[0036] Preferably, the movement direction of the first clamp body 32 is opposite to the movement direction of the second clamp body 42 .

[0037] Thus, when the steering gear 222 drives the first bidirectional screw 31 and the second bidirectional screw 41 to rotate respectively, the first clamp body 32 can be clamped and the second clamp body 42 can be loosened; or the first clamp body 32 can be loosened and the second clamp body 42 can be clamped.

[0038] In the specific implementation of the grinding and clamping device for the ammeter joint of the outdoor lightning arrester in this embodiment, the insulating telescopic rod 1 can be extended to a certain height, close to the leakage current meter joint in operation, and the threaded transmission member 22 synchronously drives the two sets of wire clamps to move. Since the movement direction of the first wire clamp body 32 is opposite to the movement direction of the second wire clamp body 42, when the insulating telescopic rod 1 rotates clockwise, the metal threaded tube 11 sequentially drives the rotating gear 111 and the steering gear 222 to make the threaded transmission rod 221 rotate relative to the adjusting arm 21. The first wire clamp clamps the leakage current meter joint under the drive of the threaded transmission part 22. At this time, the first wire clamp loosens the test line. The grinding function of the first wire clamp can be started to grind the current meter joint. When the insulating telescopic rod 1 rotates counterclockwise, the metal threaded tube 11 drives the rotating gear 111 and the steering gear 222 in turn to make the threaded transmission rod 221 rotate in the opposite direction relative to the adjustment arm 21. The second wire clamp clamps the test line under the drive of the threaded transmission part 22, and the first wire clamp loosens the leakage current meter joint. Reliable clamping is achieved after the grinding joint is rusted.

[0039] The grinding and clamping device for the ammeter connector of the outdoor lightning arrester in this embodiment can reliably short-circuit the leakage ammeter connector of the high-place lightning arrester on the ground, thereby completing the leakage ammeter short-circuit test at a higher position on the ground, replacing manual climbing or climbing and carrying insulating ladders, greatly reducing the risk of on-site operations and significantly improving work efficiency.

[0040] In other implementations of the grinding and clamping device for the ammeter connector of the outdoor lightning arrester in this embodiment, the grinding and clamping device can also be applied to other occasions where it is necessary to grind and short-circuit the high-place test equipment, such as grinding the transformer bushing connector to carry out DC resistance testing, short-circuit grounding, etc.
