[background technology]
Along with power industry develops rapidly with the direction of High Voltage Power Supply towards large unit, large capacity, how conscientiously to guarantee that the safe operation of electric power system and the power equipment moment, in stablizing good running status, are the task of top priority of current electrical management.Because the thermal effect of power equipment is the arch-criminal of various faults and anomaly, therefore, timely processing, defect elimination to isolating switch fever phenomenon, be the indispensable means that ensure power equipment reliability service.
The heating part of isolating switch is mainly at its fingertip and contact arm connecting portion, and because spring between two fingertips is tighter, therefore demolition, installation fingertip becomes a not only thing for time-consuming but also effort at the scene.After the isolating switch number of units of heating increases, the heating situation of processing isolating switch becomes a thorny thing.
Along with social development, the increasing of power load and 110kV GW4-126 type isolating switch long-play, be subject to outdoor environment to affect the serious and surperficial oxidation of contact-making surface dirt, easily causes the heating of fingertip contact portion.Processing heating and changing in fingertip process, consume a large amount of manpowers and longer operating time.Two requirements of State Grid Corporation of China to repairing work: 1, guarantee device security reliability service; 2, reduce equipment frequency of power cut and time, complete safely and reliably power supply.
Type isolating switch most heat generating spots in GW4-126 are from fingertip and contact arm junction, when processing or changing, fingertip need be pulled down, because outdoor disconnector is installed higher, and between two fingertips, spring is tighter, therefore a people has been difficult to, job site is limited, can not many people work, so will together pull down together with contact arm, on ground, carry out dismounting, during installation, need many people, because of spring tight, manpower is difficult to strut, need prize with instrument, not, understand like this silver coating of injured surface, loading onto contact arm also need be from new adjustment isolating switch, change one group of fingertip and need 3 people, used time 4-5 hour.
[utility model content]
The purpose of this utility model is for the deficiencies in the prior art, and a kind of isolating switch fingertip dismantling device is provided.
To achieve these goals, the utility model adopts following technical scheme:
An isolating switch fingertip dismantling device, comprises T-shaped driving handle, train wheel bridge, lower plate and four groups of flexible connection sheets; Wherein, every group is flexibly connected sheet and includes the first brace and the second brace, the first brace is flexibly connected with train wheel bridge, and the second brace is flexibly connected with lower plate, and by connecting rod, is flexibly connected respectively between the first brace of every two groups of flexible connection sheets and the second brace; T-shaped driving handle is welded by handle and threaded rod, and handle is perpendicular to threaded rod, and threaded rod is threaded with train wheel bridge, and the external part of threaded rod is flexibly connected with lower plate.
The utility model is further, the first brace is flexibly connected with train wheel bridge by pin, and the second brace is flexibly connected with lower plate by pin.
The utility model is further, four groups are flexibly connected in sheets every two groups and are symmetricly set between train wheel bridge and lower plate.
The utility model is further, the external part of threaded rod is provided with projection, and this projection is movably connected on lower plate by flange.
Compared with prior art, the utlity model has following advantage: the utility model GW4-126 isolating switch fingertip dismantling device can block the fingertip on main both sides by horizontal force bar when changing fingertip simultaneously, make both sides fingertip while and uniform stressed, rotary drive handle, can make both sides fingertip shrink simultaneously, convenient fingertip is removed or installed from contact arm, can the single independently working of handled easily person, facilitate work high above the ground; The utility model isolating switch fingertip dismantling device is simple in structure, flexible operation.After being applied to on-the-spot real work, guaranteeing, on the basis of equipment safety operation and staff's personal safety, to have increased substantially teams and groups' operating efficiency, and very big degree has reduced the real work amount of teams and groups.
