Abstract
A corona proof high resisting band for a high-voltage motor comprises a terylene fiberglass band, a mixing layer of carborundum and adhesive that coating on the two side surfaces and an exposed carborundum on the outer surface of the mixing layer. The corona proof band is pliable in normal temperature and capable of wrapping on the surface of different shape of objects such as wires and rods, and can compose an integrated corona proof structure associating with low resisting band and insulating layer. The corona proof band is capable of thinning the thickness of major insulating layer, improving discharge inception voltage by twofold or more, prolonging the service life of the insulting structure, reducing the interference to radio-communication and electronic equipments.
Description
Technical field
The utility model relates to a kind of anticorona high stopband that uses on high-voltage motor.
Background technology
In the prior art, the anti-corona difficult treatment of high-voltage motor insulated structure causes discharge inception voltage on the low side, the insulation system premature aging, and the corona that partial discharge causes also produces interference to radio communication and electronic equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of high-voltage motor anticorona high stopband, can improve the discharge inception voltage of insulation system, improves the bulk life time of insulation system.
The technical solution of the utility model is: the anticorona high stopband of a kind of high-voltage motor, comprise the dacron glass yarn band, be coated on the both side surface of described dacron glass yarn band carborundum and adhesive mixed layer, expose exposed carborundum at the outer surface of described carborundum and adhesive mixed layer.
The utility model compared with prior art has following advantage:
With the reinforcement of dacron glass yarn band, silicon-carbide particles are sticked with glue agent coat two-sidedly, solidify the back forms a continuous conduction on the surface aspect, control surface resistance 10
8～10
11Ω; Have flexibility under this corona-prevention belt normal temperature, can on the object surface of the different shape of, line rod etc., cooperate low stopband and insulating barrier, can form a complete anti dizzy structure.Can attenuate main insulating layer thickness, improve discharge inception voltage more than 2 times, prolong the insulation system life-span, reduce interference to radio communication, electronic equipment.

Embodiment
Referring to accompanying drawing 1, the anticorona high stopband of a kind of high-voltage motor, comprise dacron glass yarn band 1, be coated on the both side surface of described dacron glass yarn band 1 carborundum and adhesive mixed layer 2, expose exposed carborundum 3 at the outer surface of described carborundum and adhesive mixed layer 2.Add man-hour, electrician's special polyester glass tape 1 is placed on the unreeling machine, through a steeping vat, after unnecessary glue wiped off, by curing oven, harvest volume on winder became the band-type product of can the curling arbitrarily of a kind of softness, bending.The both side surface of electrician's special polyester glass tape 1 scribbles adhesive, carborundum grain, the carborundum grain is evenly distributed in the adhesive, mode by coating, be coated on the two-sided of dacron glass yarn band 1, the cured glue stick has certain contraction, and partially carbonized silicon grain is exposed on the surface, forms exposed carborundum 3, constitute the aspect of a continuous conduction, general sheet resistance 10
8～10
11Ω during use is around in high stopband 4 surface of line rod, in order to change the distribution of line rod surface field, provides the discharge inception voltage of insulation system.
Claims (1)
