Abstract
A rod-shaped porcelain insulator for high-voltage power transmission line belonging to power transmission facilities is disclosed. According to design scheme provided by the utility model, two ends of each rod-shaped porcelain insulator are respectively connected with iron caps, a connecting piece is arranged between every two iron caps, and every two rod-shaped porcelain insulators are connected with each other via the iron caps and the connecting pieces. Arc rings provided with circular rings are connected with the iron caps or the connecting pieces, and round heads are arranged at outer end of the circular rings. The insulator has good insulating property and long service life.
Description
Technical field
The utility model relates to power transmission facility, specifically a kind of insulator that is used on the ultra-high-tension power transmission line.
Background technology
In ultra-high-tension power transmission line, generally need utilize insulator to set up cable, enough insulation property are arranged between power transmission tower to guarantee the electric current on the cable.Existing insulator has disc insulator and synthetic insulator usually, and wherein, disc insulator is not owing to there is arcing ring, be a kind of can puncture type product; Synthetic insulator is made by inorganic material, in use for some time, will scrap because of aging, has influence on normal power supply.
Summary of the invention
The purpose of this utility model is to provide a kind of porcelain long rod insulator, and this insulator has good insulation preformance, characteristics such as long service life.
According to the scheme that relates to provided by the utility model, connect chapeau de fer respectively at the two ends of each long rod insulator, between per two chapeau de fers, connect the right angle link plate, per two long rod insulators utilize chapeau de fer and right angle link plate to interconnect.
On chapeau de fer or right angle connecting plate, connect arcing ring, circular rings is arranged on arcing ring, bulb is arranged in the outer end of circular rings.There is grading ring end at long rod insulator.Outer end at each chapeau de fer is provided with gap, on two support plates that form gap concentric connecting hole is set respectively, and the end plate at link plate two ends, right angle is in vertical configuration, and end plate inserts in the gap of chapeau de fer, and the through hole corresponding with connecting hole is set on end plate.Annulus is arranged on grading ring, bulb is arranged in the end of annulus.
Advantage of the present utility model: the utility model is compared with disc insulator, and intensity height, self-cleaning property be good, can not puncture, tie point is few, thereby reduced the corrosion of metals point, and be safe and reliable to operation, and disc insulator is can puncture type product, does not have arcing ring; Compare with synthetic insulator, this product material is an inorganic material, and is not aging.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Embodiment
Two ends at each long rod insulator 2 connect chapeau de fer 3 respectively, connect right angle link plate 4 between per two chapeau de fers 3, and per two long rod insulators 2 utilize chapeau de fer 3 and right angle link plate 4 to interconnect.On chapeau de fer 3 or right angle connecting plate 4, connect arcing ring 1, circular rings 6 is arranged on arcing ring 1, bulb 7 is arranged in the outer end of circular rings 6.In the end of long rod insulator 2 grading ring 5 is arranged.In the outer end of each chapeau de fer 3 gap 6 is set, on two support plates 9 that form gap 6, concentric connecting hole 7 is set respectively, the end plate 8 at right angle link plate 4 two ends is in vertical configuration, and end plate 8 inserts in the gap 6 of chapeau de fers 3, and the through hole corresponding with connecting hole 7 is set on end plate 8.Annulus 9 is arranged on grading ring 5, bulb 10 is arranged in the end of annulus 9.
Chapeau de fer 3 and long rod insulator porcelain spare are glued together, be convenient to interconnect with other parts, insulator 2 plays insulation and fixation on the line, right angle link plate 4 plays interconnect function in insulator string, arcing ring 1 is fixed on chapeau de fer 3 or the right angle connecting plate 4 and plays the striking effect, and electric arc in bulb 7 end release, makes the insulator porcelain body avoid flash burn by circular rings 6, grading ring 5 is installed in the circuit high-pressure side, plays the equalizing voltage effect.
Porcelain long rod insulator is a kind of novel very high product of technology content at present at home, and this product has been filled up domestic blank.
This product is compared with disc insulator, and intensity height, self-cleaning property be good, can not puncture, tie point is few, thereby reduced the corrosion of metals point, and be safe and reliable to operation, and disc insulator is can puncture type product, does not have arcing ring; Compare with synthetic insulator, this product material is an inorganic material, and is not aging.
This product is mainly used in rated voltage and is higher than and plays insulation and fixing cord in the interchange of 1000V or direct current overhead power line and the electric railway.
This product generally is made up of 1-4 porcelain long rod insulator unit piece according to different electric pressures, and for example, the 110kV circuit uses a joint, and the 220kV circuit uses two joints, and the 500kV circuit uses 3 joints or 4 joints.
