Abstract
The utility model relates to an auxiliary tool of a high-voltage power transmission and transformation device, in particular to a transformer substation outdoor disconnection switch auxiliary switch rain cover. The technical proposal is as follows: the tool comprises a full skirt with a downward concave surface; a sleeve with a through hole which goes through the center of the top of the full skirt and is vertically arranged; the sleeve and the full skirt are fixedly connected together; a circular ring is arranged on the circumference of the outer pipe wall on the upper top end of the sleeve; both sides of the full skirt are asymmetric, wherein, one side is provided with an open gap which can be conveniently opened so as to wrap a disconnection switch transmission lever into the through hole of the sleeve; the open gap is provided with a bolt hole for fastening; the other side of the full skirt is provided with a side sleeve; the side sleeve is provided with a side through hole; the disconnection switch operation control lever is arranged in the sleeve. The auxiliary tool has the advantages of reasonable design, careful consideration, simple structure, good rain and dust proof effect, and convenient installation and maintenance.
Description
One, technical field:
The utility model relates to a kind of aid of high-tension power transmission and transformation equipment, particularly relates to a kind of transformer station outdoor disconnecting link auxiliary switch rain cover.
Two, background technology:
At present, operation power administrative department to the auxiliary switch of the outdoor disconnecting link of transformer station because of the rainy serious problems such as causing the electric secondary circuit DC earthing of leaking, what take all is with Polypropylence Sheet wrapping, with interim measures such as sheet rubber block, not from long-range and fundamentally make the precautionary measures and deal with problems.This type of defective not only causes the outdoor switch operation rotation axis of transformer station and the corrosion of disconnecting link locking lockset serious, even because of the suitable disconnecting link drive link infiltration of rainwater disconnecting link auxiliary switch, cause that DC ground fault takes place again and again in the transformer station, directly reliable the and safety of influence power supply.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provide a kind of simple in structure, rain cover is effective and the installation and maintenance outdoor disconnecting link auxiliary switch of transformer station rain cover easily.
Its technical scheme is: comprise the full skirt that concave surface is provided with down, pass the full skirt top center and vertically be provided with the sleeve pipe that has through hole in it, sleeve pipe and full skirt are connected to one, be provided with annulus on top, sleeve pipe upper end along the outer tube wall circumference, the full skirt both sides are dissymmetrical structures, have on one side and crack, can conveniently open wide so that the disconnecting link drive link is wrapped in the through hole of sleeve pipe, crack and be provided with bolt hole so that fastening, the another side of full skirt is provided with the side sleeve pipe that has side through hole in it, and the switch operation control lever is inserted in wherein.
Wherein, described annulus and side annulus are arranged with fastening card, the utility model can be fixed on the drive link, play effects such as rain cover, dust.
In addition, described crack to be provided be used for fastening bolt hole (9).
The beneficial effects of the utility model are: the utility model is fixed on the drive link, plays effects such as rain cover, dust, it is reasonable in design, and it is thorough to consider, simple in structure, and rain cover, dust are effective, and installation and maintenance are convenient.
Four, description of drawings:
Accompanying drawing 1 is the figure that partly cuts open of the present utility model;
Accompanying drawing 2 is vertical views of the present utility model;
Among the above-mentioned figure: full skirt 1, through hole 2, sleeve pipe 3, annulus 4, crack 5, side through hole 6, side sleeve pipe 7, side annulus 8, bolt hole 9, side 10.
Five, embodiment:
For further disclosing the technical solution of the utility model, the utility model will be further described in conjunction with the accompanying drawings: as depicted in figs. 1 and 2, it comprises the full skirt 1 that concave surface is provided with down, pass full skirt 1 top center and vertically be provided with the sleeve pipe 3 that has through hole 2 in it, sleeve pipe 3 and full skirt 1 are connected to one, be provided with annulus 4 on top, sleeve pipe 3 upper end along the outer tube wall circumference, annulus can be provided with fastening card 4 times.Full skirt 1 both sides are dissymmetrical structures, have one on the side 10 and crack 5, can conveniently open wide so that the disconnecting link drive link is wrapped in the through hole 2 of sleeve pipe 3, side 10 is provided with bolt hole 9 so that fastening, the another side of full skirt 1 is provided with the side sleeve pipe 7 that has side through hole 6 in it, the switch operation control lever can be inserted in wherein, also has side annulus 8 equally, its structure is the same with sleeve pipe 3, through hole 2 and annulus 4 as shown in the figure, and the side annulus also can be provided with fastening card 8 times.Above-mentioned all by elastomeric material integrated poured compression moulding in mould.
When the utility model uses at the scene, full skirt 15 is opened wide the disconnecting link drive link is wrapped in the through hole 2 of sleeve pipe 3 from cracking, the internal diameter of through hole 2 matches with the external diameter of drive link, then the switch operation control lever is inserted in the side through hole 6 of side sleeve pipe 7, after the position of full skirt 1 is determined to make full skirt cover power transmission shaft, bolt and fastening nut will be penetrated in the bolt hole on the side 10 9, tighten the fastening card that is arranged under annulus 4 and the side annulus 8 simultaneously, the utility model can be fixed on the drive link, play effects such as rain cover, dust.Only need when carrying out grid switching operation the fastening card under annulus 4 and the side annulus 8 to be become flexible and full skirt 1 is moved on the whole, spilling the switch operation control lever can operate.
