Description
Technical field
The utility model relates to a kind of weight that suppresses suspension insulator, the windage yaw of wire jumper insulator string, belongs to high voltage circuit gold utensil technical field.
Background technology
Weight is the protective hardware adopting when straight line pole suspension insulator or strain insulator, corner and terminal shaft tower wire jumper insulator string are not enough to shaft tower clearance for insulation; existing weight comprises weight seat, heavy punch piece; heavy punch piece is arranged on weight seat, and weight seat is connected with insulator string by parallel link plate, suspension clamp, socket-clevis eye successively.Utilize standard gold utensil heavy punch piece and weight seat mounting means, material is ordered goods convenient, easily construction, but one group of weight seat is installed at most 3 heavy punch pieces (45kg) with parallel link plate, surpass 3 needs parallel link plate is installed, this mode that heavy punch piece is installed to vertical, equals to have increased electrified body length, the permission angle of oscillation of straight line pole is diminished, as unfavorable all the better in the more multipair inhibition suspension insulator windage yaw of heavy punch piece number aspect is installed.
Utilize counterweight type grading ring mounting means, by synthetic insulator producer is complete, provide, order goods convenient, be easier to construction, but grading ring is used mould, polishing need be done in surface, and processing technology is complicated, and cost is higher.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of modified model weight that suppresses suspension insulator, the windage yaw of wire jumper insulator string is provided, simplifies installing component, significantly shortened insulator string length, increased the clearance for insulation to shaft tower, easy for installation.
The modified model weight of inhibition suspension insulator described in the utility model, the windage yaw of wire jumper insulator string, comprise hammer body, on hammer body, middle side part is fixedly connected with a yoke plate, yoke plate and a pressing plate are bolted, and by nut check, fixing wire jumper between yoke plate and pressing plate, yoke plate is provided with at least three through holes, and is connected with socket-clevis eye by topmost through hole.
In the time of can be according to strong wind, wire, insulator string horizontal direction be stressed, calculate insulator string and allow required hammer body weight in angle of oscillation, hammer body and yoke plate are fixing as a whole, by yoke plate, hammer body is directly connected on socket-clevis eye, the parts such as parallel link plate, suspension clamp have been saved in centre, have significantly reduced insulator string length, increased the clearance for insulation to shaft tower, by through hole, be directly connected with socket-clevis eye, by the fixing wire jumper of pressing plate, easy for installation.
Described yoke plate is provided with three through holes from top to bottom successively, and the top through-hole diameter is 18mm, and below two through hole diameter is 14mm.
Described yoke plate is connected with pressing plate by two bolts through below two through hole, and corresponding pressing plate is provided with the through hole that two diameters are 14mm.
Described hammer body is the cylinder of diameter 100mm, and when the weight of hammer body increases, only needing increases cylindrical length, and its diameter remains unchanged, and has avoided traditional weight along with the increase of heavy punch piece, and the defect that electrified body length increases thereupon guarantees clearance for insulation.
Described hammer body and yoke plate are welded and fixed, fixed.
During use, during according to strong wind, wire, insulator string horizontal direction is stressed, calculates insulator string and allows required hammer body weight in angle of oscillation, hammer body is fixed on socket-clevis eye by yoke plate, wire jumper is fixed between yoke plate and pressing plate, by bolt-locking, completes installation.
Compared with prior art, the beneficial effect the utlity model has is:
The modified model weight of this inhibition suspension insulator, the windage yaw of wire jumper insulator string is directly connected on socket-clevis eye by yoke plate by hammer body, the parts such as parallel link plate, suspension clamp have been saved in centre, significantly reduce insulator string length, increased the clearance for insulation to shaft tower; By through hole, be directly connected with socket-clevis eye, by the fixing wire jumper of pressing plate, easy for installation; Hammer body is the cylinder of diameter 100mm, has avoided traditional weight along with the increase of heavy punch piece, and the defect that electrified body length increases thereupon guarantees clearance for insulation; Compare counterweight type grading ring, processing and fabricating is simple, reduces project cost.
