Abstract
The utility model discloses a bellmouth type ground wire operating lever head. The ground wire operating lever head comprises an operating lever clamping head. The operating lever clamping head has a structure, an upper end of the structure is in the shaped of a bellmouth, and a lower end of the structure is cylindrical; a ground wire clamping groove is disposed between the upper end and the lower end of the operating lever clamping head; the depth of the bellmouth-shaped structure is higher than the height of a ground wire head; and the lower end of the operating lever clamping head is screwed together with a screw thread of an insulation operating lever. When a ground wire is removed, because the operating lever clamping head is much larger than the ground wire head, the ground wire head can very easily enter into the operating lever clamping head; and, through rotation of the insulation operating lever, the ground wire head can clamped into the ground wire clamping groove in the operating lever clamping head; so the ground wire head is guaranteed to be firmly connected with the insulation operating lever, the operating time is shortened, and the safety of operation is also improved.
Description
Technical field:
The utility model relates to a kind of operating rod head of ground wire, particularly relates to a kind of horn mouth formula operating rod head of ground wire, is applicable in the dismounting of universal earth connection.
Background technology:
Along with economic develop rapidly, society is also more and more higher to the reliability requirement of electric power, and transformer station is an important ring in electric power system power transmission network, guarantees that Substation Operating fail safe seems particularly important.It is one of major hidden danger that transformer station's dismounting earth connection operates in all operations of transformer station.While particularly removing the earth connection of 110kV and above equipment, because equipment is higher apart from ground, the operation insulating bar joint diameter now using is basic consistent with earth terminal diameter, and three joints link together, weight is large, general personnel are difficult to once earth terminal be sticked in action bars head, if touch off because of carelessness earth terminal by mistake, probably the person and equipment are damaged.
How effectively to prevent the generation of above-mentioned these unfavorable conditions, make person on duty's operation more convenient, better ensure and Electrical Safety become the problem that current urgent need is faced and solved.
Utility model content:
Technical problem to be solved in the utility model is: a kind of horn mouth formula operating rod head of ground wire is provided, make power transformation O&M person when removing earth connection operation, can be accurate, quick, safe earth terminal be snapped in action bars joint, the potential safety hazard while eliminating earth connection dismounting.
The utility model is that the technical scheme that technical solution problem is taked is:
A horn mouth formula operating rod head of ground wire, comprises action bars dop, and described action bars dop upper end is broadening formation, lower end is cylindrical structure, between action bars dop top and bottom, is provided with earth connection draw-in groove.
Together with described action bars dop lower end is screwed in insulating bar screw thread.
The degree of depth of described broadening formation is higher than the height of earth terminal.
Also existing operation insulating bar upper end of joint can be replaced by broadening formation, the degree of depth will, higher than the degree of depth of earth terminal, guarantee that earth terminal can snap in insulating bar completely.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further explained and explanation:
Referring to Fig. 1 and Fig. 2, a kind of horn mouth formula operating rod head of ground wire, comprise action bars dop 1, action bars dop 1 upper end is broadening formation, lower end is cylindrical structure, between action bars dop 1 top and bottom, be provided with earth connection draw-in groove 2, together with action bars dop 1 lower end is screwed in insulating bar 3 screw threads, wherein: the degree of depth of broadening formation is higher than the height of earth terminal.
When removing earth connection, because action bars dop 1 of the present utility model is more much larger than earth terminal, so earth terminal will be easy to enter in action bars dop 1, by rotating insulated action bars 3, earth terminal can snap in the earth connection draw-in groove 2 in action bars dop 1, guarantee that earth terminal and insulating bar are connected firmly, shortened the operating time and also improved the fail safe operating.
Claims (3)
1. a horn mouth formula operating rod head of ground wire, comprise action bars dop (1), it is characterized in that: described action bars dop (1) upper end is broadening formation, lower end is cylindrical structure, between action bars dop (1) top and bottom, be provided with earth connection draw-in groove (2).
2. horn mouth formula operating rod head of ground wire according to claim 1, is characterized in that: together with described action bars dop (1) lower end is screwed in insulating bar (3) screw thread.
3. horn mouth formula operating rod head of ground wire according to claim 2, is characterized in that: the degree of depth of described broadening formation is higher than the height of earth terminal.
