During the replacing the end strain insulator string, the mould cavity (53) of the front fixture is locked with the twin bowl head (7) of the line hardware in a matching way, the mould cavity of the rear fixture (1) is matched with the drawing plate (8) of the line hardware and locked through a bolt, and the replacement of the whole end strain insulator string can be implemented by operating the retraction components. The fixture has the advantages that the operation is convenient, safe and stable, thereby being very suitable for the replacement of the end strain insulator string on the 800kV extra-high-voltage transmission line.
Description
Technical field
The utility model belongs to the ultra-high-tension power transmission line service kit, and what relate to is a kind of jig of changing insulator, particularly a kind of jig that is used to change strain insulator limit string.
Background technology
The existing jig that is used for the insulator string replacing of 500kV circuit strain insulator limit, card is for split type before it, and it is made up of the clamping plate that have symmetrical die cavity of two separation, and the die cavity of preceding card and line hardware hanging point are suitable, and die cavity and the right angle link plate screw that block the back are suitable.During operation, two clamping plate of preceding card get and successively are connected on the line hardware hanging point, and then pass through four wing bolts with its firm connection, load and unload all pretty troublesome; Then Ka die cavity only snaps onto on the screw of right angle link plate, and is not really reliable, in the operating process jig easily before and after play, sometimes even can overturn, have a strong impact on the stability and the safety of construction of operation.The 800kV extra high voltage network is new one-level voltage levels circuit, respective change has all taken place in the structure of circuit and the gold utensil structure on the circuit, existing jig no longer is applicable to the strain insulator limit insulator string of changing in the 800kV extra high voltage network because of the hanging point and the existing deficiency of self structure of the die cavity incompatibility new line of card before it and back card.
Summary of the invention
The purpose of this utility model is proposing a kind ofly can to adapt to the jig that 800kV grade circuit and strain insulator limit insulator string easy to operate, safety and stability are changed.
The technical scheme that realizes above-mentioned purpose is: a kind of 800KV track replacement strain insulator limit string jig, two groups of retraction assemblies at card and card two ends, back before card and back card and two ends are articulated in respectively before comprising, it is characterized in that: card is an integrated member before described, it by preceding card main body and renovating of being hinged with it form, die cavity and line hardware duplex bowl head surface shape in the middle of the preceding card are suitable; Die cavity and line hardware towing plate surface configuration in the middle of the card of described back are suitable.
Described retraction assemblies is connected to form successively by manual leading screw, insulated tension pole and hydraulic pressure leading screw.
A kind of improvement as above-mentioned technology: the material of card and back card is a titanium alloy before described.
When changing strain insulator limit insulator string, the die cavity of preceding card and line hardware duplex bowl head lock, and the die cavity of back card cooperates with the gold utensil towing plate and by a locked with bolts, operates the replacing that retraction assemblies can be implemented bunch of insulator then.
The utility model is as if preceding card is cooperated first insulator of conductor wire end of replaceable limit string with the back card of existing enclosed jig; If the back card is cooperated with the preceding card of existing enclosed jig, first insulator of replaceable limit string cross-arm end.
The utility model jig is easy to operate, and safety and stability is well suited for the replacing of 800kV extra high voltage network strain insulator limit insulator string.
