Abstract

The utility model discloses a universal ground wire. The universal ground wire comprises a ground wire clamp used for clamping the ground wire and an insulating operating rod used for being hand-held. A direction adjusting device used for changing the operation direction of the ground wire clamp is arranged between the ground wire clamp and the insulating operating rod, and the ground wire clamp is equipped with a horizontal orienting point and a vertical orienting point. The direction adjusting device comprises a universal device and an orienting connecting plate which can be connected movably and is used to set an included angle between the insulating operating rod and the ground wire clamp, one end of the orienting connecting plate is fixedly connected with a hollow shaft sleeve at the top of the insulating operating rod via a fixing nut, and the other end is connected with the horizontal orienting point or the vertical orienting point according to operation demands. The universal ground wire provided by the utility model enables the insulating operating rod to be bent and displaced, a horizontally arranged conducting wire to be grounded and also a vertical arranged conducting wire to be grounded, thereby satisfying the on-site grounding demands. The universal ground wire is simple in structure and convenient in use.

Description

Universal earth connection
Technical field
The utility model relates to a kind of universal earth connection.
Background technology
The at present domestic earth connection that generally uses generally is made up of three parts, and namely earth connection, earthing clamp, insulation hook stick are formed.The insulation hook stick length that is used for different electric pressures is also different, and is as follows according to national Specification:
1 meter of 10KV earth connection hook stick length by length;
1.5 meters of 35KV earth connection insulation hook stick length;
2 meters of 110KV earth connection insulation hook stick length;
2.5 meters of 220KV earth connection insulation hook stick length;
8 meters of 500KV earth connection insulation hook stick length;
Wherein earthing clamp forms a fixed connection with the insulation hook stick, and the rotary screw at insulation hook stick top is simultaneously for clamping earthing clamp, and such effect is to use more direct.
When the lead ground connection of horizontal arrangement, as long as the people stands on the ground or stands in overhead lower position, only need earthing clamp is hung on the lead and get final product, more laborsaving.
But, when vertically arranged lead ground connection, because earthing clamp can not be crooked with the insulation hook stick, the people must stand and just can carry out the ground connection operation on the instrument of ascending a height such as ladder, add that earth connection itself is made up of the 25mm2 copper cash, the more long total amount of earth connection is just more heavy, requires great effort very much during operation; Also have suitable danger simultaneously, because in the ground connection process, should be considered as charging equipment to this equipment, must leave enough safe distances between people and the equipment.As follows according to national safety regulation:
0.7 meter of 10KV electric pressure safe distance;
1 meter of 35KV electric pressure safe distance;
1.5 meters of 110KV electric pressure safe distances;
3 meters of 220KV electric pressure safe distances;
5 meters of 500KV electric pressure safe distances;
As seen, when various electric equipment leads are arranged vertically in the electric substation, carry out ground connection with present existing all kinds of earth connections, must cross to connect, when equipment is higher apart from ground, need to carry out parallel ground connection by the instrument of ascending a height accordingly, not only workload is big, also has suitable danger.
The utility model content
Utility model purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of universal earth connection, the insulation hook stick can be carried out bending deflection, can not only carry out the earth connection of ground connection at the lead of horizontal arrangement, can also carry out simultaneously the earth connection of ground connection at vertically arranged lead, to satisfy on-the-spot ground connection demand; Simple in structure, easy to use.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of universal earth connection comprises for the earthing clamp of clamping earth connection with for hand-held insulation hook stick, it is characterized in that: be provided with for the direction adjusting apparatus that changes the earthing clamp direction of operating between described earthing clamp and the insulation hook stick.
Described earthing clamp is provided with horizontal orientation point and vertical orientation point.
Described direction adjusting apparatus comprises universal head and the movable directed connecting plate for the angle that insulating bar and earthing clamp are set that is connected, described directed connecting plate one end is fixedlyed connected with the hollow shaft sleeve at insulating bar top by hold-down nut, and the other end is connected with horizontal orientation point or vertical orientation point according to action need.
Described insulation hook stick is the fiberglass epoxy rods.
Beneficial effect: the universal earth connection that the utility model provides, the insulation hook stick can be carried out bending deflection, the earth connection of ground connection can not only be carried out at the lead of horizontal arrangement, the earth connection of ground connection can also be carried out simultaneously at vertically arranged lead, to satisfy on-the-spot ground connection demand; Simple in structure, easy to use.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Among the figure: 1 earthing clamp; 2 insulation hook sticks; 3 horizontal orientations point; 4 vertical orientations point; 5 universal heads; 6 directed connecting plates; 7 hold-down nuts; 8 hollow shaft sleeves; 9 rotary screws.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Be illustrated in figure 1 as a kind of universal earth connection, comprise for the earthing clamp 1 of clamping earth connection with for hand-held insulation hook stick 2, it is characterized in that: be provided with for the direction adjusting apparatus that changes the earthing clamp direction of operating between described earthing clamp 1 and the insulation hook stick 2; Earthing clamp is provided with horizontal orientation point 3 and vertical orientation point 4; Direction adjusting apparatus comprises universal head 5 and the movable directed connecting plate 6 for the angle that insulating bar and earthing clamp are set that is connected, directed connecting plate one end is fixedlyed connected with the hollow shaft sleeve 8 at insulating bar top by hold-down nut 7, and the other end is connected with horizontal orientation point 3 or vertical orientation point 4 according to action need; The insulation hook stick is the fiberglass epoxy rods.
During use:
(1) ground connection of vertical wires is used:
When being in, lead is arranged vertically or when being in some specific position, can be according to circumstances crooked angle, being about to directed connecting plate 6 one is terminated on the vertical orientation point 4, one is terminated on the hollow shaft sleeve 8, and hold-down nut 7 in addition, hang up earth connection after, insulation hook stick 2 turns clockwise, rotary screw 9 can clamping wire, thereby plays the ground connection effect.
(2) horizontal arrangement lead ground connection is used:
When directed connecting plate 6 one was terminated on the horizontal orientation point 3, in like manner, earth connection can adapt at some specific position with the crooked angle of horizontal direction, is convenient to personnel's ground connection operation.
(3) ground connection under other normal conditions is used:
If do not need angle of bend, the nut 7 that is tightened after only earthing clamp 1 need being ajusted so just becomes traditional earth connection.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
