In electric power networks, for meeting the current-carrying capacity of circuit or reducing corona, split conductor is often 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.) more often sees EHV transmission lines, what be frequently encountered in the service work carrying out substation equipment is double bundle conductor。
Regulation according to 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) ", it to be carried out regular inspection prerun in every 3 years by 220kV and apparatus above。At present, bus is mainly connected on big electric current and high-tension equipment by double bundle conductor, such as the 500kV side sleeve pipe of 500kV transformator, 220kV transformator 110kV side sleeve pipe, 220kV, 500kV substation isolating-switch, spark gap etc.。Owing to double bundle conductor wire clamp itself is ined succession two wires (being generally steel-cored aluminium strand, aluminium alloy stranded conductor), the electric current flowing through wire is typically in 240A-1440A, causes that the diameter of wire is very thick, and wire clamp quality is very big；And double bundle conductor wire clamp is usually from bus farther out, and sag amplitude is big, cause that wire clamp tension is also very big, double bundle conductor wire clamp is dismantled and is filled multiple by repeatedly arriving scene, discovery there is problems in that 1, owing to double bundle conductor wire clamp is with two heavy gauge wires, quality own is big, calculate with 0.9222kg/m, so the double bundle conductor of 8m length and wire clamp will more than 15KG, calculate with 2.69kg/m, so the double bundle conductor of 8m length will reach 43KG, and double bundle conductor wire clamp is subject to the pulling force of conducting wire sag amplitude, two bolts when making last several bolts of dismounting wire clamp and fill multiple are consuming time very long, difficulty is very big, single it is 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, operating personnel accidentally will cause falling from high altitude or the injury impacted by equipment。
Utility model content
For solving above-mentioned problem, the purpose of this utility model is to provide a kind of service kit that double bundle conductor is special that dismounts, and improves double bundle conductor wire clamp and removes and fill multiple work efficiency, reduces the labor intensity of maintainer simultaneously, optimizes Manual machine effect。
The purpose of this utility model is achieved through the following technical solutions: a kind of dismount the service kit that double bundle conductor wire clamp is special, including clamping element, afterburning element and safety element, described afterburning element is screw rod and boosting-rod, described safety element is safety plug and seat 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 connected in the screw sleeve of clamping plate II after the nut of clamping plate I, described safety plug and seat belt are respectively placed in two through holes at clamping plate I back。
Clamping plate I described in the utility model are corrosion resistant plate。
Not having screw thread on the screw portion that this utility model is connected on described clamping plate II in screw sleeve, screw sleeve both sides are provided with anti-drop screw。
Safety plug described in the utility model is the pin that rustless steel is made。
Seat belt described in the utility model is common nylon rope。
This utility model carves out the multiple tiny anti-slip tank for increasing coefficient of friction respectively on the contact surface of the clamping plate I contacted with wire clamp and clamping plate II。
Compared with prior art, the beneficial effects of the utility model are:
1, when dismounting wire clamp, it is possible to make maintainer laborsaving a lot, reduce labor intensity；
2, the impact of double bundle conductor wire clamp own wt and conducting wire sag pulling force is overcome so that the time of one wire clamp of dismounting was reduced to 28.5 minutes from 52.75 minutes, substantially increased power supply reliability；
3, this specific purpose tool simple in construction, appearance looks elegant is small and exquisite, and whole instrument only has 1.2Kg, uses and carries all very convenient, and easy to operate, advantageously forms standardized work flows, also reduces personnel proficiency level's impact on service work simultaneously。
