Description
Technical field
The present invention relates to one can charged for replacement cable termination support insulator support means, belong to power system construction with
Maintenance tool field.
Technical background
Support insulator producing, transport, during installation and operation, the performance such as its machinery, insulation is by various factors shadow
Ring, in running, particularly stand the uneven effect such as mechanical force, climate change for a long time, it may appear that cracking phenomena, along with
Continuing to increase of high tension cable equipment scale, the support insulator number of cable termination cracking is also riseing year by year.Conventional column
The flow process of replacing insulator is: unclamped by the screw rod the most up and down of support insulator, now due to heavy cable termination pressure
On support insulator, can't take out；2. needing is inclined upwardly with instrument lifts cable termination base certain altitude, if mistake
Little, can not take support insulator；If excessive, " can pull " cable termination, mounting process regulation cable termination raising height should be controlled
System is within 2mm, if more than 2mm, then cable termination tail pipe inner structure size can be caused to change excessive, and longtime running can cause
Cable breakdown.According to the experience of replacing, mm more than 1 is lifted in general inclination；3. take off the support insulator of cracking, and install new
Support insulator.It is crucial that second step in three steps, then what tool tilt to lift our cable termination by
Base？The method that we use in the past was " hammer hammering method ", and the instrument of use includes trapezoidal wooden unit, bolt and bulky
Head, concrete scheme: suitable for volume trapezoidal wooden unit, bolt are placed in terminal base position, then with hammer hammering wedge shape wood
Block, promotes trapezoidal wooden unit to tilt to lift until the support insulator of cracking can be taken off by cable termination base, then carries out propping up
Post replacing insulator.
Owing to cable termination top is charged aerial line, if to change pillar in the case of cable termination does not has a power failure
Insulator, then the range of activity of operating personnel must assure that below cable termination base.And use " hammer hammering method " to carry out
When support insulator is changed, owing to the range of activity of operating personnel is considerably beyond cable termination base, it is therefore necessary to have a power failure
Could change.
Except above-mentioned needs have a power failure in addition to the shortcoming changed, and the fatal shortcoming of " hammer hammering method " another one is to change
Within in journey, cable termination base inclination raising height cannot be accurately controlled in safe altitude 2mm.Because 2mm is the least height
Degree, operating personnel is not easy to grasp and control hammer and taps frequency and the dynamics of wooden unit, and the dynamics of hammering is the most too quickly may be just
Exceed.Group has carried out correlation test investigation, finds that in Renewal process, cable termination base inclination raising height can not 100% control
System is within 2mm.
