Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary tools for power supply equipment maintenance, specifically a replacement device for a surge arrester counter in a line-outing field. Background Technology

[0002] Surge arrester counters are widely used in 110kV and above surge arresters. The counter is connected in series at the bottom of the surge arrester to record the number of times the surge arrester operates. By observing the change in continuous current, abnormalities such as aging and moisture inside the surge arrester can be effectively detected. They are generally installed outdoors, in outgoing line cabinets and other places, and the operating environment is the same as that of the surge arrester. Therefore, the failure rate of surge arrester counters is very high, and they must be replaced when damaged.

[0003] For example, patent document CN206878372U mentions a live-line replacement device for a surge arrester discharge counter, which includes an insulated operating rod, an insulated rotating screw, a lower surface of a copper clamp, an adjusting surface of a copper clamp, an upper surface of a copper clamp, an upward guide groove on the adjusting surface of the copper clamp, a shorting wire, a copper wiring lug, a shorting wire fixing bolt, an insulated top cap, insulated internal threads, and a threaded fixing pin. This utility model eliminates the long waiting time in the power outage (restoration) application and approval process, as well as potential safety hazards during power outage (restoration) operations and the deployment of safety measures; the device is compact and portable, creating economic benefits for enterprises.

[0004] While the above methods can achieve the function of replacing surge arrester counters under live conditions, in practical applications it has been found that the insulating operating rod needs to be turned several times each time the clamp is installed or removed, which is very inconvenient. Moreover, since the two clamps are set up separately, it is also inconvenient to carry the replacement device. There is still room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a replacement device for the surge arrester counter in the outgoing line field in order to solve the problems mentioned above.

[0006] The technical solution adopted by this utility model is as follows: a replacement device for a surge arrester counter in a line-outing field, comprising a fixing clamp and a shorting wire. There are two fixing clamps, each of which is provided with a wire connector connected to the shorting wire. Each fixing clamp has two clamps, and each of the two clamps has an insulated handle at its tail end.

[0007] In a preferred embodiment, the opposing end faces of the two clamps are provided with a plurality of anti-slip teeth.

[0008] In a preferred embodiment, both the clamp and the wire connector are made of conductive material.

[0009] In a preferred embodiment, the shorting conductor is a spring wire with an outer sheath and an inner multi-strand copper wire.

[0010] In a preferred embodiment, the fixing clip is an alligator clip.

[0011] In a preferred embodiment, one of the clamps has at least one locking block on its upper wall surface, and the other clamp has an inwardly recessed groove on its lower wall surface that is adapted to engage with the locking block.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, alligator clips are used as the clamping part of the grounding flat steel. When using, you only need to press the insulating handle to clamp the two clips on the flat steel. The same applies when disassembling. Compared with the traditional wire clamp mechanism, it is more convenient to install and disassemble.

[0014] 2. In this utility model, the two fixing clips are connected by a spring wire. The elasticity of the spring wire can be used to adjust the stretching length of the spring wire according to different usage scenarios, making it more applicable to a wider range of scenarios. Moreover, when not in use, the spring wire can reduce the overall size due to its rebound, making it convenient to carry the replacement device.

[0015] 3. In this utility model, a slot and a block are designed between the two fixing clips so that they can be snapped together when not in use, thus making the whole unit easy to carry. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] Reference Figure 1-4 A surge arrester counter replacement device for a line-outing field includes two fixing clips 4 and two shorting wires 1. Each fixing clip 4 is provided with a wire connector 2 that connects to the shorting wire 1. The fixing clips 4 are alligator clips and have two clamps 43. Each clamp 43 has an insulating handle 42 at its tail end. The fixing clips 4 are used as the clamping part of the flat steel 3. When in use, simply press the insulating handle 42 to clamp the two clamps 43 onto the flat steel 3. The same applies to disassembly. Compared with the traditional wire clamp mechanism, installation and disassembly are more convenient. The alligator clip is a known structure and its specific structure will not be described here.

[0023] Furthermore, multiple anti-slip teeth 41 are provided on the opposite end faces of the two clamps 43. The anti-slip teeth 41 can increase the friction between the clamps 43 and the flat steel 3, thereby improving the strength of the clamp 4 when holding the flat steel 3.

[0024] Furthermore, both the clamp 43 and the wire connector 2 are made of conductive materials, so that after the clamp 43 is clamped onto the flat steel 3, a sibling conductive circuit can be formed, allowing operation to be performed without power outages to the line and surge arrester.

[0025] Furthermore, the shorting wire 1 is made of spring wire with outer insulation and multiple copper wires inside. The two fixing clips 4 are connected by the spring wire. By utilizing the elasticity of the spring wire, the stretching length of the shorting wire 1 can be adjusted according to different usage scenarios, making it more applicable. Moreover, when not in use, the shorting wire 1 can reduce its overall size due to the rebound effect, thus facilitating the carrying of the replacement device.

[0026] Furthermore, the upper wall of the clamp head 43 of one of the clamping clips 4 is provided with at least one locking block 432, and the lower wall of the clamp head 43 of the other clamping clip 4 is recessed inward to form a locking groove 431 that is adapted to engage with the locking block 432. The locking groove 431 and the locking block 432 that can be locked together are designed between the two clamping clips 4, so that the two clamping clips 4 can be locked together when not in use, thereby facilitating the overall carrying. The locking structure is a commonly used structure, and the specific structure will not be described here.

[0027] The specific operating procedure is as follows: When installing the live replacement device for the discharge counter, one of the fixing clips 4 should first be fixed to the grounding terminal of the discharge counter (i.e., the flat steel 3). Figure 4 (As shown at point b), then fix another fixing clip 4 to the conductor end of the discharge counter (i.e., flat steel 3) (as shown). Figure 4 (As shown at point a), then quickly remove the fault discharge counter, replace it with a new discharge counter, and then remove the two fixing clips 4.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
