Embodiment Construction
[0015] Such as figure 1 , figure 2 As shown, this embodiment disclosed in this embodiment, a new type of grounding small vehicle conductive arm device that can be applied to different sizes, including a fixed seat 1, vertical slider 2, vertical slide 3, a corner code 4, vertical adjustment screw 5, the conductive arm 6 and the horizontal adjustment screw 7.
[0016] The fixing seat 1 of the present embodiment is a rectangular parallelepiped plate member on the front side and the width direction in the longitudinal direction, and the top plate and the bottom plate are symmetrically disposed in the intermediate position of the intermediate position.
[0017] A circular hole is opened at the center position of the width side of the fixing seat 1.
[0018] The cross-sectional shape of the vertical slider 2 is T-shaped, connected to the intermediate position of the back surface of the fixed seat 1, after the connection, the end plate of the vertical slider 2 is parallel to the backplan...

The invention discloses a novel grounding trolley conductive arm device applicable to switch cabinets with different sizes. The novel grounding trolley conductive arm device comprises a fixed seat, a vertical sliding block, a vertical sliding rail, a vertical adjusting assembly and a conductive arm; the fixed seat is a cuboid-shaped plate frame seat of which one side in the length direction and one side in the width direction are open sides; and the vertical sliding block is connected to the outer side of a side plate in the length direction of the fixing base, the vertical sliding rail matched with the vertical sliding block is fixed to a trolley body of the electricity testing trolley, and the fixing base is assembled on the vertical sliding rail through the vertical sliding block. The vertical adjusting assembly is fixed to the portion, corresponding to the lower portion of the vertical sliding rail, of the electricity testing trolley body, and after the fixing base is assembled on the vertical sliding rail, adjustment of the vertical position is achieved through the vertical adjusting assembly. The length of the conductive arm is adjustable, and the conductive arm is vertically assembled in the fixed seat and can slide along the length direction of the fixed seat to adjust the horizontal position after being assembled. Therefore, the grounding trolley can realize grounding of 800mm and 1000mm switch cabinets by using the same grounding trolley.
Description
Technical field [0001] The present invention relates to an electrical device switchgear, and more particularly to a new type of grounding trail electroding arm device that can be applied to different sizes of switchgear. Background technique [0002] At present, the 10kV switchgear ground car is now widely used in all kinds of 10kV switchgear, but the existing 10kv feeder and 10kV main switch cabinet size is not uniform, and the commonly used 10kV feeder switchgear is 800mm wide, 10kv main switchgear The size is 1000 mm wide, different sizes of switch cabinet contact spacing is also different, and the switchgear for different sizes needs to be equipped with different models of grounding cars. Considering the redundant configuration (two of the same ground trolley configuration, when it is damaged, it is available), and a substation is required to configure at least 8 units. On the one hand, it is not economical and on the other hand, the maintenance workload of the ground trolley...
