Description
Technical field
The present invention relates to a kind of replacing two string anti-fouling type porcelain insulator instrument, particularly a kind of earth potential live replacing two string anti-fouling type porcelain insulator splitting.
Background technology
In transmission line, anti-fouling type porcelain insulator is generally used in strain insulator circuit, it includes steel cap, bulb and porcelain insulating sub-pieces, wherein steel cap and bulb lay respectively at the front-end and back-end of porcelain insulating sub-pieces, like this by the steel cap of a rear porcelain insulating sub-pieces being connected to the bulb of last porcelain insulating sub-pieces, thus multiple porcelain insulating sub-pieces is connected into string.Because the structure of porcelain insulating sub-pieces is as skirt, porcelain patticoat is to downward-extension as straw hat, and the recess in straw hat type porcelain patticoat and bulb can only contract, like this, the junction of steel ball and bulb is also positioned at the recess of this straw hat type porcelain patticoat.
When carrying out earth potential live replacing to two string anti-fouling type porcelain insulator, needing the spring catch at fech connection place, can enough realize separating of insulator string.Conventional splitting includes vice body and jaw, vice body and jaw in the same plane, for straight-plate-type, but owing to being recessed in porcelain patticoat in the link position of insulator, the splitting of straight plate structure not only needs to select special angle that jaw is stretched into recess in porcelain patticoat, also want to clamp spring catch simultaneously, cannot realize in the short space of this recess in porcelain patticoat, therefore in prior art, realize carrying out charged for replacement to two string anti-fouling type porcelain insulator, can only be that operating personnel enters electric field operation replacing, or power-off is changed, but this must bring the complexity of operation, personnel's personal safety cannot ensure, power supply reliability is poor, large on power grid operation impact.
Summary of the invention
The object of the invention is to provide according to the deficiencies in the prior art part a kind of simple to operate, fail safe is high, reliability is strong, effective guarantee power grid operation, realizes the two anti-fouling type porcelain insulator splitting of going here and there of earth potential live replacing.
The object of the invention is to be realized by following approach:
Earth potential live replacing two string anti-fouling type porcelain insulator splitting, include vice body and jaw, its structural feature is, vice body is made up of two pincers pin, include flat part and bend, the plane of bend and the plane of flat part are 110 °-150 ° and arrange, crooked position deflects 40 °-60 ° in the bearing of trend of flat part to side simultaneously, jaw is positioned at the upper end of bend, the plane of jaw and the flat part place plane parallel of vice body, thus, the flat part of the relative vice body of jaw deflects 40 °-60 ° to side; Be provided with fixed connecting rod at a wherein embedding pin tail end of vice body, it is perpendicular to pincers pin, and be hinged with arc-shaped guide rail part near the position of pincers pin, the top being positioned at fixed connecting rod is provided with action bars connecting portion; Another root pincers pin tail end of vice body is provided with guide rod, and this guide rod is arranged in the guide rail of arc-shaped guide rail part.
Splitting of the present invention changes conventional pliers vice body and jaw is in conplane structure, be provided with the bend that can change jaw height and flexibility, define the splitting of a S type structure, break the conventional structure of the straight plate of splitting, make it meet the environmental structure of recess bulb and steel cap junction in anti-pollution type insulator, thus make operation become simple and convenient.During operation, insulating bar is connected with action bars connecting portion, pulls open the tail end of two pincers pin, arc-shaped guide rail sheet launches, and now jaw opens, and then the jaw of splitting is stretched into recess alignment springs pin in anti-fouling type porcelain insulator porcelain patticoat, stir arc-shaped guide rail sheet, make it to move backward, relative guide rail just drives the pincers pin tail end at its place close to another root pincers pin, until merge, now jaw closes, bite spring catch, splitting withdrawn from by mobile insulating bar, completes the charged for replacement to anti-pollution type insulator.Thus, splitting of the present invention achieves the object of earth potential live replacing anti-pollution type insulator, simple, convenient and reliable, electric field is entered without the need to personnel, ensure personal safety, improve processing safety, simultaneously the also effective guarantee safety of electrical network, stable operation.
The present invention can be specially further:
Described fixed connecting rod one end is riveted and is fixed on a pincers pin of vice body, and a termination of arc-shaped guide rail part is connected with this fixed connecting rod, and can with this fixed connecting rod for axle rotates.
Like this, fixed connecting rod just becomes the rotating shaft of arc-shaped guide rail part, when arc-shaped guide rail part rotates along fixed connecting rod, the guide rod be arranged on another root pincers pin just slidably reciprocates at guide rail, thus realize its near or away from fixed connecting rod, realize the closed of two pincers pin further or open, finally completing occlusion and the release of jaw.
The operation connecting rod connected at fixed connecting rod top is a kind of circular connector.
The insulating bar one end of carrying out earth potential operation can penetrate or be threaded this circular connector, realizes connecting, convenient operation.
Guide rail on described arc-shaped guide rail part is closed guide rail, and the length of this closed guide rail and the A/F of jaw match, and maximum length can make the A/F of jaw be greater than the end cross-sectional of spring catch in insulator.
Guide rod is automatically limited at the two ends of guide rail thus, when rotating arc rail guide piece, only needs two blind ends guide rod being operated guide rail, easy to operate.
In sum, the invention provides a kind of earth potential live replacing two string anti-fouling type porcelain insulator splitting, its broken the straight plate of splitting conventional structure and invented S type structure splitting, it is made to meet the environmental structure of recess bulb and steel cap junction in anti-pollution type insulator, simple, convenient and reliable, enter electric field without the need to personnel, ensure personal safety, improve processing safety, simultaneously the also effective guarantee safety of electrical network, stable operation.
