Description
Technical field
The present invention relates to insulator chain live-line replacing technical field of tools, be a kind of livewire work bowl head regular worker
Tool.
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
Outside weight by wire and metal-ware, it is necessary to bear the wind load under inclement weather conditions, snow load, conductor galloping and fortune
The overvoltage impact that impact load that defeated installation process misoperation causes and thunder and lightning, switching manipulation cause.Currently used 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, making moist, cause plug hydrolysis, efflorescence, burn into variable color, plug section overall mechanical strength declines, and makees at normal mechanical load
Can rupture under with.It is thus desirable to patrol and examine, timely the most more on 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 connection wire, composite insulator by socket-clevis eye and suspension clamp at present
String lower end have bulb, socket-clevis eye top to have the bowl head of band bowl slotted eye, bowl slotted eye be oriented generally perpendicular to wire direction or
Identical with wire direction, in ball-head cover is contained in bowl slotted eye and to fix spacing by M shape pin, 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 towards 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 renewed, and bulb can be fixed by M shape pin, complete relevant operation, but for installing
Composite insulator string in the bowl slotted eye being perpendicular to 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 uses manual pulley suspender to mention wire on wire, to be composite absolutely
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, owing to socket-clevis eye easily tilts because of deadweight, it is impossible to the bulb of composite insulator string is loaded bowl
In slotted eye and fixed by M shape pin, be merely able to closely be operated 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
The socket-clevis eye in slotted eye vertical wires direction there is problems in that socket-clevis eye easily tilt, be not fixed easily spacing, composite insulator
String bulb cannot install, cannot realize livewire work carries out maintenance and changes, and upkeep operation not only time length, labor intensity are big, and
And waste time and energy, work efficiency relatively low.
Additionally, wide due to power supply radiation because of ultra-high-tension power transmission line, social influence, economic impact that power failure causes are relatively big,
Power supply enterprise, for ensureing continued power, is the most all to make a plan to carry out maintenance task when having a power failure, enters ultra-high-tension power transmission line
Row maintenance and maintenance, replacing composite insulator string, owing to can not eliminate defect in time, service work is relatively more passive, there is safety
Hidden danger, once the composite insulator string damage of band defect can cause accidental power failure, causes the bigger loss of supply.
Summary of the invention
The invention provides a kind of livewire work bowl head setting tool, overcome the deficiency of above-mentioned prior art, it can have
Effect solve existing bowl slotted eye vertical wires direction socket-clevis eye easily tilt, be not fixed easily spacing, composite insulator string bulb without
Method is installed, cannot be realized livewire work, change activity duration length, waste time and energy, work efficiency relatively low, it is impossible to change existence in time
The problem of potential safety hazard.
