Abstract
The invention discloses a bar-shaped suspension ceramic insulator. The insulator comprises a ceramic piece, iron caps, adhesive, washers and a locking pin. The ceramic piece is made of moderately strong ceramic. An umbrella skirt is arranged on the surface of the ceramic piece. Two ends of the ceramic piece are connected with the iron caps in a sleeved manner. The iron caps are fixedly connected with the ceramic piece via the adhesive. The washers are arranged on joints of end faces of the two ends of the ceramic piece and the iron caps. The height of the bar-shaped suspension ceramic insulator body formed by the ceramic piece and the iron caps is 390mm. The diameter of the umbrella skirt is 150mm. The insulator is mainly used on a 10KV-110KV power transmission circuit, so creepage distance and dry arcing distance are increased, the creepage distance is increased by about 60%, and pollution flashover frequency can be reduced.
Description
Technical field
The present invention relates to a kind of porcelain insulator, specifically a kind of Clavate suspension type porcelain insulator.
Background technology
The Clavate suspension type porcelain insulator that electric company uses on 10KV-110KV transmission line is generally the porcelain insulator of XP-70 model, the product creepage distance of this model is short, along with power consumption increases year by year, circuit operating load constantly expands, often pollution flashover phenomenon is there is in the porcelain insulator of above-mentioned model in transmission operation, and the frequency of pollution flashover phenomenon is high, circuit is caused often power-off fault to occur.
Summary of the invention
The object of the present invention is to provide a kind of Clavate suspension type porcelain insulator, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of Clavate suspension type porcelain insulator, comprise porcelain piece, chapeau de fer, adhesive, pad and locking pin, strong porcelain during porcelain piece adopts, and the surface of porcelain piece is provided with full skirt, porcelain piece two ends are all socketed chapeau de fer, chapeau de fer is fastenedly connected by adhesive and porcelain piece, and porcelain piece two ends end face and chapeau de fer junction arrange pad, in use procedure, the end of chapeau de fer connects power transmission tower frame by hot-galvanized steel pin, the height of the Clavate suspension type porcelain insulator body that described porcelain piece and chapeau de fer are formed is 390mm, and the diameter of full skirt is 150mm, makes creepage distance >=500mm.
As the further scheme of the present invention: described adhesive is made up of 525# portland cement and quartz sand, play the effect of gummed.
As the further scheme of the present invention: pad adopts felt paper to make.
As the further scheme of the present invention: the top of described chapeau de fer arranges locking pin, locking pin adopts W stainless steel to make.
As the further scheme of the present invention: chapeau de fer is hot galvanizing chapeau de fer.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is mainly used on transmission line 10KV-110KV circuit, increases creepage distance, dry arcing distance, it is significantly about 60% that its creepage distance adds, increase dry arcing distance, pollution flashover frequency can be reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of Clavate suspension type porcelain insulator, comprises porcelain piece 1, chapeau de fer 2, adhesive 3, pad 4 and locking pin 5, strong porcelain during porcelain piece 1 adopts, and the surface of porcelain piece 1 is provided with full skirt, to strengthen creepage distance.
Porcelain piece 1 two ends are all socketed chapeau de fer 2, chapeau de fer 2 is fastenedly connected by adhesive 3 and porcelain piece 1, and porcelain piece 1 two ends end face and chapeau de fer 2 junction arrange pad 4, pad 4 adopts felt paper to make, thus play the effect of insulation, the top of described chapeau de fer 2 arranges locking pin 5, and locking pin 5 adopts W stainless steel to make.
