[embodiment]
In order to understand the utility model better, below with reference to accompanying drawing and instantiation, the utility model is described in detail.
For the compression mounting or dismounting earth connection time, complete grid switching operation fast, shorten and stop the power transmission operating time, the utility model provides a kind of quick joining type earthing device.Refer to Fig. 2, the decomposition texture schematic diagram of the quick joining type earthing device that the utility model preferred embodiment provides.As shown in Figure 2, this quick joining type earthing device comprises earth rod 10, earth connection 20, copper sheet 30 and rapid grounding external member 40.
Copper sheet 30, for being bent into the brace at right angle, it offering two earth rod connecting holes 32, another side offers snap joint connecting hole 34.Corresponding with on earth rod 10 of the aperture of earth rod connecting hole 32 and spacing, is fixed on copper sheet on earth rod 10 by fixed screw 12.
Snap joint external member 40 comprises quiet joint (hold-down screw 42, maternal interface 44) and dynamic joint (male joint 46, hexagon socket head cap screw 48).Quiet joint is connected on copper sheet 20, and dynamic joint is connected on earth connection 20.More particularly, maternal interface 44, through the snap joint connecting hole 34 on copper sheet, is fixed on copper sheet 30 by hold-down screw 42; Contact chip 22 on earth connection 20 is connected with dynamic joint with hexagon socket head cap screw 48.Quick joining type earthing device after having connected as shown in Figure 3.
Incorporated by reference to consulting Fig. 4, when needs carry out ground connection installation, only dynamic joint (male joint 46) access connecting earth connection 20 need be connected in the quiet joint (maternal interface 44) on earth rod 10.
Otherwise, but when needing to carry out ground connection dismounting, only need to move joint (male joint 46) and extract in quiet joint (maternal interface 44).
Detect through experiment, after adopting above-mentioned quick joining type earthing device, connect the used time and remove used time average out to 17 seconds and 24 seconds.
Hinge structure, quick joining type earthing device of the present utility model at least has significant advantage in the following aspects:
(1) economic benefit.Utilize connect soon transformation traditional earth connection often group need input 58 yuan/× 3=168 yuan.According to statistics Xianfeng County Utilities Electric Co. every year because nut damages, to come off and 110kV earth connection 1 group is scrapped in distortion, quotation 760 yuan/group, 35kV earth connection 10 groups, quotation 580 yuan/group, 10kV earth connection 40 groups, quotation 480 yuan/group, amounts to about 25760 yuan.After transformation, earth connection normally uses and can reach two test periods, namely 10 years.The current existing 110kV earth connection 4 groups of Xianfeng County Utilities Electric Co., 35kV earth connection 40 groups, 10kV earth connection 120 groups, all transformation needs fund 168 yuan/group × 164 group=28536 yuan.25760 yuan/year × 10 years within 10 years, can be saved-28536 yuan=229064 yuan according to current price-level and all constant reckoning of other factors.In addition, stop electric power feeding time because saving, the economic benefit that power supply station produces in advance cannot calculate one by one at this.
(2) social benefit.Through improving, reduce operating personnel's labour intensity.
The above exemplifying embodiment only have expressed some embodiments of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
