Technical field
The present invention relates to electric power system power transformation technology field, be specifically related to service kit equipment being removed and fills multiple double bundle conductor wire clamp.
Background technology
In electric power networks, for meeting the ampacity of circuit or reducing corona, bundle conductor often can be used to connect power equipment.Current double bundle conductor is widely used in big current loop or the voltage levels converting equipment of each transformer station; and multiple fission conductor (quadripartion, six-multiple conductor etc.) is more common in EHV transmission lines, what often can run in the service work carrying out substation equipment is double bundle conductor.
According to the regulation of Southern Power Grid Company " power equipment preventive trial code " (Q/CSG114002-2011) and Yunnan Power Grid Company " equipment state overhauling and prerun regular inspection and preventive maintenance work implement directions suggestion (2013 editions) ", 220kV and above equipment will carry out regular inspection prerun to it in every 3 years.At present, bus is mainly connected on big current and high-tension equipment by double bundle conductor, as the 500kV side sleeve pipe, 220kV transformer 110kV side sleeve pipe, 220kV, 500kV substation isolating-switch, lightning arrester etc. of 500kV transformer.Because double bundle conductor wire clamp itself is ined succession two wires (being generally steel reinforced aluminium conductor, aluminium alloy stranded conductor), the electric current flowing through wire is generally at 240A-1440A, and cause the diameter of wire very thick, wire clamp quality is very large, and double bundle conductor wire clamp is usually far away apart from bus, and sag amplitude is large, the pulling force causing wire clamp to be subject to is also very large, double bundle conductor wire clamp is dismantled and is filled multiple by repeatedly arriving scene, there is following problem in discovery: 1, because double bundle conductor wire clamp is with two heavy gauge wires, quality own is large, calculate with 0.9222kg/m, the double bundle conductor that so 8m is long and wire clamp will more than 15KG, calculate with 2.69kg/m, the double bundle conductor that so 8m is long will reach 43KG, and double bundle conductor wire clamp is subject to the pulling force of conducting wire sag amplitude, make the last several bolt dismantling wire clamp consuming time very long with two bolts when filling multiple, difficulty is very large, singlely to be difficult to, 2, in dismounting double bundle conductor wire clamp process, when operating personnel works on the equipment such as inclination bushing, because not trampling a little reliably, and ladder truck and aerial work platform narrow space, the injury that operating personnel accidentally will cause falling from high altitude or be impacted by equipment.
Summary of the invention
For solving the above problems, the object of this invention is to provide the service kit that a kind of dismounting double bundle conductor is special, improving double bundle conductor wire clamp and remove and fill multiple operating efficiency, reducing the labour intensity of maintainer simultaneously, optimize Manual machine effect.
The object of the invention is to be achieved through the following technical solutions: the service kit that a kind of dismounting double bundle conductor wire clamp is special, comprise clamping element, afterburning element and safety element, described afterburning element is screw rod and boosting-rod, described safety element is safety plug and safety belt, it is characterized in that: described clamping element is made up of clamping plate I and clamping plate II, described clamping plate I are L-type, described clamping plate II offer a square recess, clamping plate II are connected on L-type clamping plate I by square recess, described clamping plate I are welded with a nut above it, the back of clamping plate I is provided with two through holes, described clamping plate II are welded with a screw sleeve, described screw rod is through being connected in the screw sleeve of clamping plate II after the nut of clamping plate I, screw rod is connected in the part in screw sleeve does not have screw thread, described safety plug and safety belt are placed in two through holes at clamping plate I back respectively.
Clamping plate I of the present invention are corrosion resistant plate.
The present invention carves out the multiple tiny anti-slip tank being used for increasing coefficient of friction respectively on the contact-making surface of the clamping plate I contacted with wire clamp and clamping plate II.
Safety plug of the present invention is the made pin of stainless steel.
Safety belt of the present invention is common nylon rope.
Compared with prior art, the invention has the beneficial effects as follows:
1, when dismounting wire clamp, maintainer can be made much laborsaving, reduce labour intensity;
2, overcome the impact of double bundle conductor wire clamp own wt and conducting wire sag pulling force, make the time of a dismounting wire clamp reduce to 28.5 minutes from 52.75 minutes, substantially increase power supply reliability;
3, this specific purpose tool structure is simple, and appearance looks elegant is small and exquisite, and whole instrument only has 1.2Kg, uses and carries all very convenient, and easy to operate, is conducive to forming standardized work flows, also reduces the impact of personnel's qualification on service work simultaneously.
