Description
Technical field
This utility model is related to insulator chain live-line replacing technical field of tools, is that a kind of livewire work bowl head is fixed
Instrument.
Background technology
Insulator rises in overhead transmission line and supports wire and prevent electric current from returning the important function on ground, and insulator is except holding
Weight by wire and metal-ware outer it is necessary to wind load under bearing inclement weather conditions, snow load, conductor galloping and fortune
Impact load that defeated installation process misoperation causes and the overvoltage that thunder and lightning, switching manipulation cause impact.At present using relatively
Many is composite insulator string, and it can make porcelain insulator quality unstable under the influence of the factors such as thunder and lightning, birds, dense fog, dense fog
The short circuit current of flashover can make insulator heating burst, and also can produce galvanic corrosion and damage under electric field action, causes sheath to destroy and enter
Water, make moist, lead to plug hydrolysis, efflorescence, burn into variable color, plug section overall mechanical strength declines, make in normal mechanical load
With under can rupture.It is thus desirable to patrolling and examining, timely more to the composite insulator string of defective, damage, residual old impact power supply
Change, prevent the generation of transmission line malfunction and accident.
Many composite insulator strings are had to hang connecting wire, composite insulator by socket-clevis eye and suspension clamp at present
There is bulb string lower end, and the bowl head with bowl slotted eye arranged at socket-clevis eye top, bowl slotted eye be oriented generally perpendicular to wire direction or
Identical with wire direction, bulb is sleeved in bowl slotted eye and spacing by the fixation of M shape pin, and socket-clevis eye bottom is provided with catenary
Folder, wire hangs and is arranged in suspension clamp.When changing composite insulator string, for being arranged on, direction is consistent with wire direction
Composite insulator string in bowl slotted eye, have at present specific purpose tool can M shape pin in removal bowl slotted eye, by bulb in bowl slotted eye
After the composite insulator string take out, more renewing, and bulb can be fixed, complete related operation by M shape pin, but for installation
In the composite insulator string in the bowl slotted eye in wire direction, this specific purpose tool cannot use, after being merely able to wait power failure,
Maintainer climbs up wire along composite insulator string, stands in and lifts wire using manual pulley suspender on wire, to be composite exhausted
Remove M shape pin when edge substring relaxes, bulb is taken out in bowl slotted eye, unloads defective composite insulator string, install afterwards
During new composite insulator string, because socket-clevis eye easily tilts because of deadweight it is impossible to the bulb of composite insulator string is loaded bowl
Fixed in slotted eye and by M shape pin, be merely able to closely operate by operator, complete to install, finally by manual pulley
Suspender loosens wire, makes composite insulator string stress, takes off manual pulley suspender and fulfils assignment.Therefore, at present for existing bowl
There is problems with the socket-clevis eye in slotted eye vertical wires direction：Socket-clevis eye easily tilts, is not fixed easily spacing, composite insulator
String bulb cannot install, cannot realize livewire work carry out maintenance change, upkeep operation not only time length, high labor intensive, and
And waste time and energy, work efficiency relatively low.
Additionally, because of ultra-high-tension power transmission line because power supply radiation is wide, the social influence causing that has a power failure, economic impact are larger,
Power supply enterprise is to ensure continued power, is all generally to make a plan to carry out maintenance task when having a power failure, ultra-high-tension power transmission line is entered
Row maintenance and maintenance, replacing composite insulator string, due to can not eliminate defect in time, service work is more passive, there is safety
Hidden danger, once the composite insulator string damage with defect can lead to accidental power failure, causes the bigger loss of supply.
