Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of electric substation of the utility model ground line configuration schematic diagram;
Fig. 2 is the active joint schematic diagram that a kind of electric substation of the utility model uses earth connection;
Embodiment
Extremely shown in Figure 2 as Fig. 1, be a kind of electric substation of the utility model earth connection, comprise insulating bar 1 and wire clamp 2, described wire clamp comprises clamping limb 20, following clamping limb 21 and is located at the described clamping element of going up between clamping limb 20 and the following clamping limb 21 22, described clamping element 22 is connected by screw rod 3 with described insulating bar 1, the described clamping limb 20 of going up is provided with governor motion between the clamping limb 21 down with described, described governor motion be used for regulating described go up clamping limb 20 and described under distance between the clamping limb 21.
Concrete, described adjustment structure comprises slot 23 and inserted link 24, and described slot 23 is fixedlyed connected with described clamping limb 21 down, and described inserted link 24 is fixedlyed connected with the described clamping limb 20 of going up, and can adopt the mode of welding.Be equipped with some fixing holes 25 on described slot 23 and the described inserted link 24, when the fixing hole 25 on the fixing hole 25 on the described slot 23 and the different described inserted links 24 is corresponding, distance between two described clamping limbs 21 is different, reaches the purpose of regulating the aperture between the described clamping limb 21.Described fixing hole 25 is used for wearing securing member 26, and described securing member 26 plays the locking effect, after the locking, keeps the distance between two described clamping limbs 21 constant.In the present embodiment, the distance between the described clamping limb 21 is 80mm-150mm.
Be provided with the concaveconvex structure for guiding between described adjustment structure and the described clamping element, described concaveconvex structure comprises gathering sill and fin, and described gathering sill moves along described fin and leads.In the present embodiment, described slot 23 is provided with fin 27 with inserted link 24, and the gathering sill 28 on the described clamping element 22, described gathering sill 28 are fastened on the described fin 27, and described fin 27 and gathering sill 28 are used for the described clamping element 22 of restriction and rotate.Described clamping element 22 moves along described fin 27, make described clamping element 22 move and not rotate along clamping direction, can guarantee to clamp effect, and only produce active force perpendicular to equipment surface in equipment surface that avoiding relatively rotating with equipment surface scratch occurs.In addition to the implementation, also can be located on described slot and the inserted link by described gathering sill, described fin is located on the described clamping element.
Be provided with active joint between described clamping element 22 and the described screw rod, described active joint comprises the connecting portion 31 that is located at described screw rod 3 tops and the connection chamber 29 that is located at described clamping element 22 diapires, and described connecting portion 31 is contained in the described connection chamber.Concrete, described connecting portion and described connection chamber are sphere.31 years old described screw rod of described connecting portion rotates in described connection chamber 29 synchronously, and drives described clamping element 22 and move.
