G) tighten up bolt after, the electrician is sent to ground with instrument on the tower, tower under the personnel, end-of-job is worked well and is summed up and record.
Though the activity duration of the earth potential mode of operation of above-mentioned steps can be reduced to about 20 minutes, improved the efficient of work greatly, reduced the cost of manpower and physics, also need develop corresponding tools for live working, could in practical application, implement.
Summary of the invention
To the deficiency of prior art, the utility model proposes a kind of instrument of realizing the charged fastening circuit suspension clamp U-bolt of earth potential operation carrying out.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of instrument of charged fastening circuit suspension clamp U-bolt, and it comprises action bars and box socket set; Wherein, action bars adopts insulating material to process, the be rotationally connected handle of box socket set of one of which end.
As a kind of improvement, realize being rotationally connected between insulating bar and the box socket set with connector in the utility model; One end of connector flexibly connects an end of action bars, the be rotationally connected handle of box socket set of the other end of connector.Preferably, between the end of said connector and action bars for being threaded; Be connected through bearing pin between the handle of said connector and box socket set.Connector can adopt process of the prior art to process.
As a kind of improvement, the end of said action bars is provided with metal connector, and connector inside and connector are provided with coadapted screw thread.Concrete, insulating material is processed because action bars is selected epoxy resin etc. for use, itself is difficult to the connector with metal, perhaps is generally between the ratchet spanner handle that stainless steel processes to connect.Adopt the connector identical to be connected the above-mentioned problem that solved with connector with the action bars diameter.The material of connector should select for use the high material of intensity to process, and is preferably duralumin, and its length should not surpass 100mm, and preferably end and edge all are processed into circular arc.
Preferably, the said action bars of the utility model is a hollow stem, its inner filled and process.Because action bars will guarantee the safe distance of operating personnel and electrified body, thus need to test through permeability test, power frequency withstand test, hygrometric state dielectric test, insulation tolerance, and mechanical test could be selected for use after qualified.The type of action bars can be solid hopkinson bar, hollow pipe, or the hollow stem of inner filled and process, and density of material should not be lower than 1.75g/cm
3, water absorption rate is not more than 0.3%, is preferably epoxide resin material and processes, diameter 28mm, the hollow stem of wall thickness 2.5mm, the inwall of the bonding hollow stem of filled and process.
The total length of insulating bar is by the decision of the summation of the shortest effective insulated lengths, end metal joint length and portion of the handle length, and its each several part length requirement is with reference to table 1:
Table 1: action bars each several part length requirement
With 220kV is example, considers tower structure, and under the prerequisite that every length all meets the demands, the length of getting insulating bar is 3.5m.
In the power frequency withstand test, the insulating material of insulating bar is carried out the 1min power frequency withstand test of 300mm test product; In the hygrometric state dielectric test, the insulating material of insulating bar is carried out the 1h rain test of 1200mm test product, test product should satisfy no flashover under 100 kV power-frequency voltages, does not have to puncture, and the surface does not have visible electric leakage evidence of corrosion, the requirements such as temperature rise that can not find; During insulation tolerance can be tested, insulating bar wanted tolerate 1min power-frequency voltage test between two electrodes of the 300mm of being separated by, and test product is no flashover under the 100kV power-frequency voltage, does not have to puncture, and it is thus clear that surperficial nothing is the evidence of corrosion that leaks electricity, the requirements such as temperature rise that can not find; In addition, insulating bar should have certain mechanical bending resistance, antitorque characteristic, and anti-extruding, anti-mechanical aging performance; After 4000 bend cycles of experience; When not using visual inspection by amplifying device, test product should not have the vestige of any damage, and any permanent deformation does not have yet.
The described connector of the utility model can adopt screw rod of the prior art, utilizes the existing processes means to change a social system, and also can directly utilize the existing processes means to process.Be preferably, the length of the threaded portion of an end is 4.5cm on the connector, and pin shaft hole is set on the other end, simultaneously corresponding pin shaft hole is set also on the handle of box socket set, utilizes bearing pin that both are coupled together, and can realize being rotationally connected.The installation of connector for ease connects, and is preferably at the middle part of connector nut is set.
The said box socket set of the utility model can be selected existing box socket set for use; Existing processes also capable of using is processed, and its handle embeds the afterbody of sleeve, and formation is rotationally connected between the sleeve; Sleeve can rotate to be adjusted to required angle by thorny handle, fixes then.
Moment of torsion during general manual dismounting nut is 10000Ncm, and people's thrust is 250N, and the decreased food of box socket set is L=10000/250=40cm thus.The screw rod of considering the wire clamp U-bolt is generally longer, so the length of sleeve is preferably 10cm.
When the utility model has solved charged secure wires suspension clamp U-bolt; Adopt earth potential to operate the problem that lacks corresponding hot-line tool; Insulating bar has guaranteed the safe distance between staff and the electrified body; Action bars and being rotationally connected of box socket set have made things convenient for the operation of screwing or dismantling to the wire clamp U-bolt simultaneously, make the whole operation process reduce elapsed time and man power and material, have improved operating efficiency.
