【Detailed ways】

In order to better understand the utility model, the utility model will be described in detail below in conjunction with the accompanying drawings and specific examples. the

In order to shorten the time for assembling and disassembling the grounding wire, quickly complete the switching operation, and shorten the operation time for stopping power transmission, the utility model provides a quick-connecting grounding device. Please refer to FIG. 2 , which is a schematic exploded structure diagram of the quick-connect grounding device provided by a preferred embodiment of the present invention. As shown in FIG. 2 , the quick-connect grounding device includes a ground rod 10 , a ground wire 20 , a copper sheet 30 and a quick ground kit 40 . the

The copper sheet 30 is a connecting piece bent into a right angle, with two ground rod connecting holes 32 on one side and a quick connector connecting hole 34 on the other side. The aperture and spacing of the connecting holes 32 of the grounding rod correspond to those on the grounding rod 10 , and the copper sheet can be fixed on the grounding rod 10 by fixing screws 12 . the

The quick joint set 40 includes a static joint (fixing screw 42 , female interface 44 ) and a moving joint (male joint 46 , socket head cap screw 48 ). The static joint is connected on the copper sheet 20 , and the moving joint is connected on the ground wire 20 . More specifically, the fixing screw 42 passes through the quick joint connection hole 34 on the copper sheet, and the female interface 44 is fixed on the copper sheet 30; After the connection is completed, the quick-connect grounding device is shown in Figure 3. the

Please refer to FIG. 4 in conjunction with FIG. 4 . When grounding installation is required, it is only necessary to connect the moving joint (male joint 46 ) connected to the grounding wire 20 into the static joint (female joint 44 ) connected to the grounding rod 10 . the

On the contrary, when the grounding needs to be removed, it is only necessary to pull out the moving joint (male joint 46 ) from the static joint (female joint 44 ). the

Through experimental testing, after adopting the above-mentioned quick-connect type grounding device, the connection time and removal time are 17 seconds and 24 seconds on average. the

Compared with the prior art, the quick-connect grounding device of the present invention has significant advantages at least in the following aspects:

(1) Economic benefits. It needs to invest 58 yuan/piece × 3 pieces = 168 yuan per group to transform the traditional grounding wires by quick connection. According to statistics, Xianfeng County Electric Power Company scraps 1 set of 110kV grounding wires every year due to nut damage, falling off and deformation, and the quotation is 760 yuan/set; 10 sets of 35kV grounding wires are quoted at 580 yuan/set; , a total of about 25,760 yuan. After the transformation, the normal use of the grounding wire can reach two test periods, that is, 10 years. Xianfeng County Electric Power Company currently has 4 groups of 110kV grounding wires, 40 groups of 35kV grounding wires, and 120 groups of 10kV grounding wires. All reconstruction needs funds of 168 yuan/group×164 groups=28536 yuan. According to the current price level and other factors, it can be calculated that 25,760 yuan per year × 10 years - 28,536 yuan = 229,064 yuan can be saved in 10 years. In addition, due to saving the time of power outage, the economic benefits generated by power supply in advance cannot be estimated here one by one. the

(2) Social benefits. After improvement, the labor intensity of operators is reduced. the

The above-mentioned implementation examples only express some implementations of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the present utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the scope of protection of the utility model patent should be based on the appended claims. the
