Abstract
The utility model is related to a knock-down magnetic earthing wire used for the installation of power transmission and a distribution device. The knock-down magnetic earthing wire includes a seat and a handle pole. On the top of the seat is a fixed screw thread connection unit that can be connected to the earthing screw of the equipment to be maintained. A flexible knot is arranged inside the hollow of the screw thread connection unit, and the earthing screw is fixed on the flexible knot. On the top of the handle pole is an operation bushing. The inner diameter of the bushing adapts to the outer diameter of the lower part of the seat. On the lower part of the seat is a transverse dowel, while on the top of the operation bushing there is a longitudinal slot adapting to the dowel. The utility model is small in size, easy to operate, and safe.
Description
Technical field
The utility model relates to a kind of magnetic dismountable type earth connection that is used for the equipment for power transmission and distribution installation and maintenance.
Background technology
The earth connection that uses in the power equipment maintenance process, its effect are assurance equipment reliable grounds in maintenance process, to ensure the safety of attendant and equipment.In the maintenance process of equipment such as some ring main units, cable branch box and electric substation's switch cubicle, because this type of device space is less, the cabinet pattern is changeable, thereby traditional circuit, power transformation type earth connection can't be suitable for, and uses the self-control earthing device at present mostly.Defectives such as these homemade earthing device not only exist and take up room greatly, operation inconvenience, and its fail safe also can not get guaranteeing.
Summary of the invention
Technical problem to be solved in the utility model is the magnetic dismountable type earth connection that takes up room little, easy to operate, that fail safe is good when a kind of the use is provided.
Magnetic dismountable type earth connection of the present utility model comprises a pedestal and an action bars, pedestal upper end be fixed be used for desire service equipment on the threaded connector that is connected of ground connection screw thread, the difference of the thread forms of safeguarding according to desire, this threaded connector can be one section nut or one section bolt; The middle part of described threaded connector is set with a kink, is fixed with on the kink to be used for the earth stud that is connected with earth lead; The top of described action bars is provided with an operation sleeve pipe, and the internal diameter of operation sleeve pipe and the external diameter of pedestal hypomere are fixed with horizontal bayonet lock for movingly at the pedestal hypomere, has the draw-in groove longitudinally that cooperates with bayonet lock at operation sleeve pipe top simultaneously; In addition, be fixed with permanent magnet in the endoporus bottom of operation sleeve pipe, corresponding with it, the material of pedestal lower end is a ferrimagnet.
The utility model is because owing to utilize magnetic material to realize being connected of pedestal and action bars, after being connected, the equipment that makes pedestal and desire safeguard easily action bars to be shirked, reduce the space hold of earth connection greatly, also improved the fail safe and the convenience of operation.

Fig. 1 is the base structure schematic diagram of an embodiment of the utility model;
Fig. 2 is the base structure schematic diagram of another embodiment of the utility model;
Fig. 3 is the structural representation of action bars of the present utility model.
Embodiment
Magnetic dismountable type earth connection of the present utility model comprises a pedestal 1 and an action bars 2.
As shown in Figure 1 and Figure 2, pedestal 1 upper end be fixed be used for desire service equipment on the threaded connector 3 that is connected of ground connection screw thread, the difference of the thread forms of safeguarding according to desire, this threaded connector can be one section nut (as Fig. 1) or one section bolt (as Fig. 2); The middle part of threaded connector 3 is set with a kink 4, is fixed with on the kink to be used for the earth stud 5 that is connected with earth lead.As shown in Figure 3, the top of action bars 2 is provided with an operation sleeve pipe 6, and the operation sleeve pipe can be enclosed within on the hypomere of pedestal 1, is fixed with horizontal bayonet lock 7 at the pedestal hypomere, has the draw-in groove longitudinally 8 that cooperates with bayonet lock at operation sleeve pipe top simultaneously.Utilize like this action bars with the operating sleeve pipe box at the pedestal hypomere, and after making bayonet lock snap in draw-in groove, just can the threaded connector on the pedestal be connected with screw thread on desiring service equipment by the rotating operation bar.Shirk in order to make pedestal 1 can either be connected preferably and be easy to action bars 2, be fixed with permanent magnet 9 in the endoporus bottom of operation sleeve pipe 6, corresponding with it, the material of pedestal lower end is a ferrimagnet.
