Abstract

The utility model discloses a novel portable short-circuit ground wire, which is composed of a conducting wire end terminal, a short-circuit wire, a ground end terminal and a ground operating rod, wherein one end of the ground operating rod is provided with an electroscope and the other end of the ground operating rod is provided with a plurality of operating hooks of which the opening directions are different. Correspondingly, the upper side and the lower side of the conducting wire end terminal are respectively provided with a circular ring; the position of the end terminal body, which is opposite to a press tongue, is provided with an 8-shaped hole. Correspondingly, the press tongue is also provided with an 8-shaped hole, and a control pin passes through the hole. In the course of use, the novel portable short-circuit grounding wire can be separated with the conducting wire end terminal. The hanging and the taking are convenient. The novel portable short-circuit grounding wire is suitable for conducting wires of different thicknesses. The utility model has the advantages of novel structure, convenient operation, high safety, operating time and labour saving and high work efficiency.

Description

A kind of new-type portable short-circuit grounding wire

Technical field:

The utility model relates to a kind of electric equipment and earthy safety appliance of circuit temporary short-circuit of will having a power failure, particularly relates to a kind of new-type portable short-circuit grounding wire.

Background technology:

Earth connection is to be used for when electric power facility is overhauled electric equipment and the earthy safety appliance of circuit temporary short-circuit of having a power failure, its objective is for the surplus electric charge of drainage, prevent dangerous voltage and electric arc when incoming call, or the influence generation induced voltage of contiguous charging equipment and circuit, cause the staff to get an electric shock and die or third-degree burn.Therefore, " by electrical safe working order " requirement correctly select short-circuit grounding wire, determine the quantity and the hitch point of suspension, can avoid dangerous voltage and effect of arc.At present, short-circuit grounding wire commonly used is made up of conductor wire end wire clamp, short-circuit line, earth terminal wire clamp and ground connection hook stick, during use, the conductor wire end wire clamp is fixed on the ground connection hook stick, short-circuit line one terminates on the conductor wire end wire clamp, the other end is connected on the earth terminal wire clamp, above-mentioned part is formed a whole, use, before articulating, earlier carry out electrical verification, confirm to articulate behind the no electricity with electroscope.In practical operation, find that existing short-circuit grounding wire has the following disadvantages: 1. because the increasing of electric pressure, the air gap of lead and shaft tower is increasing, the distance of lead and body of the tower is also more and more far away, and existing ground connection action bars limited length, very hard when the staff stretches forward hanging earthing conductor, and dangerous, in addition, after work is finished, earth connection can't directly be fetched with hand at all, can only it be taken after with the uncinate gyrus of earth connection action bars by other instrument again, and some staff is in order to save trouble, use the hand wobble earth connection, action bars swung take after getting back in the hand, this has seriously violated operational procedure, and is abnormally dangerous.2. need transmit earth connection and electroscope up and down in practical operation, time-consuming, effort makes the operating time long.3. use existing earth connection, on the straight line pole cross-arm during hanging earthing conductor, because the opening direction of conductor wire end wire clamp up, weigh down at earth connection under the effect of power, the easy and lead disengaging of wire clamp, and on the strain insulator shaft tower, because the angle of ground wire bar and lead is too small, weigh down under the power effect at wind-force and earth connection, the also easy and lead disengaging of wire clamp, even card is disconnected.4. wire clamp presses tongue to be in closure state under spring action, and the opening of formation is less, and is very inconvenient when hanging on large-section lead.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of new-type portable short-circuit grounding wire, the problem that this earth connection can avoid prior art to exist, increase work efficiency, and it is rational in infrastructure, use easy to operate, the technical scheme that the utility model adopted is as follows: the utility model comprises the conductor wire end wire clamp, short-circuit line, earth terminal wire clamp and earth rod are formed, and it is characterized in that an end of ground connection hook stick is established electroscope, and the other end is provided with the different operation hook of several opening directions, correspondingly, the conductor wire end wire clamp respectively be provided with an annulus up and down, be hinged between annulus and the wire clamp, can rotate mutually.

3 of aforesaid operations hook operated by rotary motion can satisfy instructions for use.During operation, at first the electroscope with hook stick one end carries out electrical verification to lead, after confirming no electricity, re-use the operation hook, hook wire clamp, it is suspended to the hanging point place that chooses by the annulus above the wire clamp, take off hook stick then, at this moment, if it is unreal to find that wire clamp contacts with lead, hooks annulus below the wire clamp by the operation hook on the hook stick again and pull down wire clamp and can make its tight contact.

In order to adapt to large-section lead, can be on the wire clamp clamp, " a 8 " font hole is opened at the position relative with pressing tongue, correspondingly, press on the tongue and also offer " a 8 " font hole, wear a control pin in the hole, the two ends of pin are respectively equipped with the retaining head, the diameter of retaining head is greater than the last hole in " 8 " font hole, and, before the hanging wire folder, will press tongue to place deployed position less than following hole, the control pin then places the place, last hole in " 8 " font hole, to press tongue location, hang up properly wire clamp after, sell to setting aside control with hook stick, make the control pin slide into the place, following hole in " 8 " font hole, at this moment, press tongue under spring action, can reset lead is tightly clamped, guarantee that contact closely.

Compared with prior art, the utility model novel structure, easy and simple to handle, safe and reliable, can save the activity duration, and save time, laborsaving, increase work efficiency;

Specific embodiments:

The utility model comprises conductor wire end wire clamp 8, short-circuit line 12, earth terminal wire clamp and ground connection hook stick 2, wherein an end of ground connection hook stick is connected with electroscope 1, the other end is provided with three operation hooks 3 that opening direction is different, 4, correspondingly, respectively be provided with annulus 6 up and down at the conductor wire end wire clamp, 10, be hinged between annulus and the wire clamp, can rotate each other, simultaneously, in order to adapt to large-section lead 7, on the clamp of wire clamp, the position relative with pressing tongue 9 is provided with " a 8 " font hole, correspondingly, press on the tongue and be provided with " 8 " font hole 5 yet, wear a control pin 11 in the hole, the two ends public affairs of pin are not provided with the retaining head, the diameter of retaining head is greater than the last hole in " 8 " font hole, and less than its following hole, will press tongue to place the enable possition by the control pin before using, be articulated on the lead after, stir the control pin with hook stick, make its following hole that changes " 8 " font hole over to, at this moment, press just resilience under spring action of tongue, compress lead, and closely contact.
