Description
Technical field
It is resistance in particular to a kind of charged for replacement transformer station 500kV the present invention relates to the instrument and method for changing insulator chain
Open the instrument and method of insulator chain.
Background technology
With the construction and development of 500kV ehv power transmission systems, 500kV power networks have become the tie of national network
And artery, it is also regional power grid main skeleton, very important effect is played to the safe and stable operation of whole power network.500kV
Transformer station is that the connection of 500kV systems dominates point again, is come from the structure type many-side of electric power netting safe running requirement and power network
See, transformer station's livewire work be it is necessary be also frequently, wherein change strain insulator string be regular work again.According to
From the point of view of present transformer station livewire work situation, 500kV strain insulators are heavier due to its own, and it often goes here and there weight for 300kg, long
Spend for 5m or so, wire tightens up tension force about 3-5t, therefore non-in transformer station's charged for replacement 500kV strain insulator string difficulty
Chang great.Conventional method is to use bottle-holding rack, uses drawing method drawing length for 150-200mm, the construction stress when tightening up line
Very big, the bottle-holding rack structural danger being integrated for horizontal force and vertical force is big, and the more heavy installation of kit is not
Just.
The content of the invention
Present invention aims to overcome that above-mentioned prior art and a kind of charged for replacement transformer station 500kV strain insulators are provided
The instrument and method of string, to solve to change the difficult problem of transformer station 500kV strain insulator strings livewire work.
Realize that the technical scheme that the object of the invention is used is a kind of work of charged for replacement transformer station 500kV strain insulator strings
Tool, the instrument includes card, single head screw mandrel, insulation coaster, insulated tension pole on link plate clamping tool, insulator, and the link plate clamping tool is fixed
Scheduled in being fixed on insulator chain side of wire yoke plate, insulator on second insulator of insulator chain to be replaced, single head screw mandrel
The both sides blocked on link plate clamping tool and insulator are arranged on, insulation coaster is on link plate clamping tool；One end of insulated tension pole is by embracing
Hoop is fixed on framework, and the other end is connected with link plate clamping tool.
In addition, the present invention also provides a kind of using instrument progress replacing insulator string method, this method includes following
Step：
S100, installation fixture：Equipotential electrician hangs on link plate clamping tool, insulated tension pole, single head screw mandrel, card on insulator, absolutely
Edge coaster instrument, is installed at insulator chain two ends to be replaced；
S200, installation insulation coaster, replacing insulator chain is tied up to by insulated sling through the insulation coaster on link plate clamping tool
The 3rd insulator on；
S300, tighten up single head screw mandrel to shift the load of insulator chain first insulator to be replaced to single head screw mandrel；
S400, the connecting bolt for removing insulator chain first insulator socket-clevis eye to be replaced and yoke plate；
S500, relaxation single head screw mandrel are to shift the load of insulator chain to be replaced to insulated tension pole；
S600, replacing insulator chain；
S700, relaxation single head leading screw simultaneously remove replacing instrument.
Using the present invention in replacing insulator under electrified operation without using bottle-holding rack, pass through micro- drawing method of crossing and change insulator
String so that operation crosses drawing length and is reduced to 15mm or so by original 150-200mm, greatly reduces the mistake for tightening up line operation
Haulage, thus wire construction stress when tightening up line is greatly reduced, improve the safe coefficient of operation.
