Stable operation, this just needs to replace problem insulator.
With socio-economic development, requirement of the people to power supply reliability is higher and higher, therefore in order to reduce line outage
Time generally carries out more changing jobs for insulator chain using livewire work mode in real work.It insulate for general straight line
Substring generally uses insulation ropes method to be replaced, and utilizes insulation ropes by conducting wire pull-up, the tower operator by ground staff
It cooperates replacing insulator string.
This operational method has the following disadvantages: first is that can only replace to single stress point insulator chain, for double points
It splits, the conducting wires such as quadripartion can not carry out replacing insulator；Second is that pulling insulation ropes using manpower, security and stability is poor, if with
Power is too quickly to be may cause to cross-arm safe distance deficiency, and line discharge tripping, human casualty accident are caused；Third is that needing operation people
The more, limited personnel of member, is not available large pitch operation；Fourth is that insulation ropes pulling force is big, it is high to require insulation performance, if
Insulation ropes save improper dampness, may cause fracture in the course of work and personnel's electric shock accidents even occurs.
In 220kV V-type string conductors on quad bundled, since conducting wire is quadripartion, conducting wire stress point is four, and insulator
Impact direction of going here and there is not vertical direction, more changing jobs for insulator string can not be carried out using conventional insulation ropes method, so that 220kV
The insulator of V-type string conductors on quad bundled can not be replaced in the way of livewire work, can only be replaced, be reduced using power failure mode
The safety of operation of power networks, or even cause large-area power-cuts.
Utility model content
In view of the foregoing defects the prior art has, the utility model proposes a kind of insulation of 220kV conductors on quad bundled V-type
Substring replaces tool.
The utility model, which is that the following technical solution is employed, to be realized:

Stick, be connected to along longitudinal direction respectively two it is adjustable insulation pull-rod tops straight line lead screw and be connected to two adjustable insulation pull-rods
The four line hook of insulation of bottom end, is respectively symmetrically set with angle steel fixture on two straight line lead screws, in symmetrical two angle steel fixtures
Between be connected in turn to pull rod and lead screw, pull rod is fixedly connected with lead screw.
Further, two groups of hook cards of four line hooks of the insulation are equipped with enclosuring structure.
Further, the adjustable insulation pull-rod includes preceding card insulation pull-rod and rear card insulate pull-rod, preceding card insulation pull-rod
Middle and lower part be equipped with the downward inner hole of aperture, the outer diameter of rear card insulation pull-rod is less than the diameter of the inner hole of preceding card insulation pull-rod,
The middle and upper part of card insulation pull-rod and the middle and lower part of preceding card insulation pull-rod are respectively equipped with through side wall and equally distributed circular hole afterwards；Afterwards
Before card insulation pull-rod is inserted into the inner hole of card insulation pull-rod, circular hole is passed through for preceding card insulation pull-rod and rear card insulation drawing by bolt
Stick connection.
Compared with prior art, the utility model has the beneficial effects that
(1) replacement 220kV conductors on quad bundled V-type insulator is carried out without having a power failure, and livewire work mode can be used and replace.
(2) insulator crossarm can be made lateral stressed the design of pull rod and lead screw, insulator crossarm is avoided to be destroyed by cross force.
(3) replacement insulation subprocess can be used straight line lead screw and lift conducting wire, pulls without manpower, needs operating personnel's quantity
It reduces, security and stability is higher.
(4) insulate four line hooks design so that utility model device can be used for the replacement of conductors on quad bundled insulator chain,
Adjustable insulation pull-rod can be according to insulator model, live physical condition adjustment length, and the scope of application is wider.
(5) livewire work range is extended, power off time is reduced, increases more power supply volumes, bring a large amount of economic benefits and society
It can benefit.
