Description
Technical field
The invention belongs to removing ice of power transmission line to maintain equipment fields, and in particular to a kind of transmission line of electricity spiral blasting type deicing
Device.
Background technique
Transmission line of electricity is typically erected in open field environment, the moisture when winter environment temperature reduces, in air
It can condense and form icing on the transmission line, and powerline ice-covering will cause following harm:
(1) shaft tower is damaged.Transmission line icing is blocked up, and shaft tower machinery loading can be made more to carry and fracture.
(2) line tripping.For the route of conducting wire vertical arrangement, when the icing on layer conductor first falls off instantly (on conducting wire
Icing not necessarily fall off simultaneously), conducting wire will rise rapidly or jump above and below, cause phase fault, jump line switching
Lock, power failure.
(3) insulator chain inclination, conducting wire are seriously sagging.When ice covering thickness in each span of route is uneven, conducting wire sag
Great changes will take place by general, and suspension insulator is caused to tilt, and fitting bears biggish horizontal direction active force.It is blocked up in icing
In span, it is serious sagging and ground fault occurs to will cause conducting wire.
(4) after insulator chain icing, it will be greatly reduced insulation performance.When suspension insulator icing dissolves, possible shape
At icicle, keeps insulator chain short-circuit, cause ground fault.
Currently used mode of getting rid of the danger mainly has ice-melt and two kinds of mechanical deicing, and wherein ice-melting mode is in power transmission line
To realize ice-melt, concrete mode has trend distribution formula ice-melt (increase in the short time power line load and heat production), short for upper heating
Road formula ice-melt (transmission line of electricity suitable for three phase supply), high frequency pumping ice-melt are (using the kelvin effect of high-frequency high-voltage, defeated
