According to the utility model, the installation of electrical equipment and rectangular bus ground wires is convenient and firm and the security of overhauling operating personnel can be ensured.
Description
Technical field
The utility model relates to a kind of electric power overhaul power tool, particularly a kind of rectangular bus bar earth connection link that uses in transformer station.
Background technology
At present, for guaranteeing the reliability service of power system device, many electric equipments need periodic inspection, to the overhaul of the equipments in the transformer station time, need repair apparatus is had a power failure and the installing earth connection, to guarantee the safety of staff and equipment; To the hard bus attaching of 10kV rectangle ground wire, can be subjected to condition influence such as the device space usually, the earth point of accidental equipment and earth connection loose contact phenomenon influence equipment and staff's safety, also can certain obstruction be arranged to workmen's work; Be the person and the device security of guaranteeing the staff, install and space characteristic in conjunction with the hard bus of rectangle, and on-the-spot actual conditions, develop 10kV rectangular bus bar earth connection link; The employing of earth connection link not only can be shortened the operating time, improves operating efficiency, also makes earth point more obvious, and protected equipment ground point contacts tightr with earth connection, protection service work personnel, the fail safe of raising overhaul of the equipments work.
The utility model content
The purpose of this utility model provides a kind of in transformer station upkeep operation scene, satisfies and guarantee the special-purpose earthing tool of upkeep operation of job safety needs: rectangular bus bar earth connection link.
For achieving the above object, technical solution of the present utility model is: a kind of rectangular bus bar earth connection link, and it links bar, packing washer, bolt combination by rectangular metal frame, insulating sleeve, spiral shell and constitutes; Link bar at spiral shell of the minor face center of rectangular metal frame welding, spiral shell links packing washer and nut is housed on the bar, framework outer wrap at the rectangular metal frame has one deck insulating sleeve, and another minor face center of rectangular metal frame is provided with an opening that does not have wrap insulate sheath bare metal frame.
Earth connection link rectangular metal frame is of a size of: long 130～140mm, wide 90～95mm, spiral shell link the materials processing that bar and rectangular metal frame 5 are selected Φ 12～14mm for use.
Spiral shell links 2 spring pads, 2 packing rings and 3 nuts is housed on the bar altogether.
The employing of rectangular bus bar earth connection link can make the easy for installation, firm of electric equipment and rectangular bus bar earth connection, has guaranteed upkeep operation personnel's safety.
Description of drawings
Fig. 1 is rectangular bus bar earth connection link structural representation;
In the drawings, 1-spiral shell links bar, 2-packing washer, 3-nut, 4-insulating sleeve, 5-rectangular metal frame;
Fig. 2 is rectangular bus bar earth connection link three-dimensional view.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model, structure are described in further detail:
By Fig. 1, Fig. 2 as can be seen, rectangular bus bar earth connection link links bar 1, packing washer 2, nut 3 by rectangular metal frame 5, insulating sleeve 4, spiral shell and constitutes, link bar 1 at spiral shell of the minor face center of rectangular metal frame 5 welding, spiral shell links packing washer 2 and nut 3 is housed on the bar 1, and rectangular metal frame and spiral shell link bar and can adopt circular aluminium bar to make; Framework outer wrap at rectangular metal frame 5 has one deck insulating sleeve 4, insulating sleeve adopts the rare basic composite insulation silastic material of 110 methyl second, there is an opening that does not have wrap insulate sheath bare metal frame another minor face center of rectangular metal frame 5, the size of opening can be 35mm, and opening part is used for connecting earth connection.
Earth connection link rectangular metal frame 5 is of a size of: 130～140mm, wide 90～95mm, spiral shell link the materials processing that bar 1 and rectangular metal frame 5 are selected Φ 12～14mm for use, spiral shell button length of connecting rod 70～75mm.
In order to ensure the reliable connection between earth connection and bus, spiral shell links 2 spring pads, 2 packing rings and 3 nuts is housed on the bar 1 altogether, to satisfy the needs that are fixed and clamped.
Rectangular bus bar earth connection link needs to open in the earth connection attachment point of rectangular bus bar or switch aluminium row turnover line one of the circular hole of diameter 16mm in use, and link is installed firmly in mounting points, earth connection is connected with link to get final product again.
