Description

1000kV strain tower of transmission line hard wire jumper is grounded Special wire-clip
Technical field
The conductor wire end wire-clamping device being grounded in field of power is the utility model is related to, is specially 1000kV power transmission lines Road anchor support hard wire jumper ground wire Special wire-clip.
Background technology
According to Q/GDW1799.2-2013 State Grid Corporation of China electric power safety working regulation(Circuit pack)It is required that in electric power Work on circuit, ensure that safe technical measures have:Power failure, electrical verification, ground connection, use personal safety wire and suspension nameplate and dress If cover bar(Fence).After circuit performs power failure operation and the clear and definite no-voltage of experience, respectively held in job site has with job site Each branch line of possible anti-power transmission(Including user)Ground wire should be all installed immediately, and ground wire should be fixed on using dedicated wire clamp On conductor, forbid being grounded with the method for winding or short-circuit.
It is the complete ground wire of general extra-high voltage that UHV transmission line, which has a power failure used in hanging earthing conductor later, at present, its Sectional area, length and wire clamp can meet normal use in most cases, but if work on the spot is needed using hard On the anchor support of wire jumper during hanging earthing conductor, the conducting wire end terminal of ground wire will be fixed on hard wire jumper pipe mother's conductor spacer, existing Ground wire conducting wire end terminal pipe mother's conductor spacer cannot firmly be clamped due to shape and size problem, especially in strong wind weather wire clamp Easily disengage ineffective.Therefore, it is special there is an urgent need to develop a kind of 1000kV strain tower of transmission line hard wire jumper ground wire Wire clamp, to ensure that line outage job safety is carried out.
The content of the invention
The ground wire conducting wire end terminal now used because shape, dimensional problem cannot dead earth line well, operation process In there are security risk, therefore the utility model provides a kind of 1000kV strain tower of transmission line hard wire jumper ground wire industrial siding Folder, improves existing wire clamp, so as to improve the reliability of wire clamp, it is ensured that the safety development of line outage operation.
The utility model adopts the following technical scheme that realization:1000kV strain tower of transmission line hard wire jumper is grounded Line Special wire-clip, including left and right clamping plate, left and right clamping plate are connected with spring by fixed spring pin, made in the plate face of left and right clamping plate Reed is fixed with reed fixing bolt, mandril is fixed with left clamp, mandril pin is fixed with right clamping plate, is gone back in left clamp The rope fixing pin that comes off is fixed with, ground wire fixing bolt is further fixed on right clamping plate.
In use, first pinching out wire clamp lower part, ejector rod part top is nailed on to crown bar pin, clamping plate is opened completely.Pass through The ground wire of lower part connection puts wire clamp to stereoplasm tube mother's conductor spacer, and under the effect of gravity, mandril disengages, and clamping plate is acted in spring It is lower to clamp conductor spacer.
Above-mentioned 1000kV strain tower of transmission line hard wire jumper ground wire Special wire-clip, the top of left and right clamping plate is towards infolding It is curved.Under clamping plate head is fixed jointly with reed, wire clamp can be securely held on pipe mother's conductor spacer.
The 1000kV power transmission line ground wire wire clamps used now be by 500kV power transmission line ground wires wire clamp improve and Come, its conducting wire end terminal major design is used for clamping solid conductor, for clamping 1000kV strain tower of transmission line hard wire jumpers During pipe mother's conductor spacer, its shapes and sizes is not very suitable, easily disengages and causes ground wire to fail.For this reason, the utility model root Carried out according to the shapes and sizes earth wire conducting wire end terminal of 1000kV strain tower of transmission line hard wire jumper pipe mother's conductor spacers Reformed AHP, redesigns wire clamp shape, increases its snap-in force and frictional force, its clamping is more bonded, no Easily disengage failure.
The utility model employs new clamping plate head first, by curved clamping plate head, between clamping plate head and stereoplasm tube mother Interact every rod, a upward reaction force can be provided;Secondly, by increasing reed on clamping plate, make reed with it is hard Matter pipe mother conductor spacer interacts, and can provide a downward reaction force, under the action of upper and lower two active forces, make line What folder can be consolidated more is clamped on wire jumper pipe mother's conductor spacer, is not easy to disengage under the effect of the external force such as wind-force, improves ground connection Reliability, ensure that operating personnel safety.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is wire clamp left clamp front view.
Fig. 3 is the right clamping plate front view of wire clamp.
In figure:1- clamping plates, 2- reeds, 3- reed fixing bolts, 4- mandril pins, 5- mandrils, 6- springs, 7- come off rope admittedly Rationed marketing is followed closely, 8- ground wire fixing bolts, 9- ground wires, and 10- is grounded the rope that comes off, 11- fixed spring pins.
Embodiment
With reference to attached drawing, the utility model is further illustrated.As shown in the figure:The utility model wire clamp includes left and right and presss from both sides Plate 1, the reed 2 being fixed on using reed fixing bolt 3 on clamping plate, the mandril pin 4 and ground wire being fixed on the clamping plate of right side Fixing bolt 8, the mandril 5 being fixed on the clamping plate of left side and the rope fixing pin 7 that comes off.Spring pin company is provided with the clamping plate of left and right Lug, left and right clamping plate are connected by fixed spring pin 11 with spring 6, are grounded the rope 10 that comes off and are fixed on the rope fixing pin that comes off On 7, after having used ground wire, for the ground wire that comes off.Ground wire 9 is fixed on folder on the right side of wire clamp by being grounded fixing bolt 8 On plate.It is trapezium structure symmetrical above and below, wire clamp or so in the middle part of 1000kV strain tower of transmission line hard wire jumper pipe mothers conductor spacer Under the curved head of clamping plate and reed collective effect, wire clamp can be tightly fixed in the middle part of conductor spacer, ensure the reliability of ground connection.
In the present embodiment, clamping plate 1, mandril 5 all use aluminum alloy material, not only ensure that electric conductivity, but also alleviate weight;Reed 2 use copper reed, ensure that enough elasticity and electric conductivity;Reed fixing bolt 3, mandril pin 4, spring 6, the rope that comes off are solid Rationed marketing nail 7, ground wire fixing bolt 8, fixed spring pin 11 use stainless steel, ensure enough rigidity and durability; Ground wire comes off rope 10 using silk rope, ensures carrying portable and intensity;Ground wire 9 uses band transparent sheath and sectional area is not Multiply annealed copper wire less than 25 square millimeters.
