Description
Technical field
The invention belongs to removing ice of power transmission line maintained equipment field, and in particular to a kind of transmission line of electricity spiral blasting type deicing
Device.
Background technology
Transmission line of electricity is typically erected in open wild environment, when winter environment temperature reduces, the moisture in air
It can condense in and icing is formed on transmission line of electricity, and powerline ice-covering can cause following harm：
(1) shaft tower is damaged.Line ice coating is blocked up, and shaft tower machinery loading can be made more to carry and fracture.
(2) line tripping.The circuit being arranged vertically for wire, when the icing on layer conductor first comes off instantly (on wire
Icing not necessarily come off simultaneously), wire will rise rapidly or upper and lower jump, causes phase fault, jumps line switching
Lock, power failure.
(3) insulator chain inclination, wire are seriously sagging.When ice covering thickness in each span of circuit is uneven, conducting wire sag
Great changes will take place by general, causes suspension insulator to tilt, gold utensil bears larger horizontal direction active force.It is blocked up in icing
In span, wire can be caused serious sagging and ground fault occurs.
(4) after insulator chain icing, insulating properties can be substantially reduced.When suspension insulator icing dissolves, possible shape
Into icicle, make insulator chain short-circuit, cause ground fault.
The mode of getting rid of the danger used at present mainly has two kinds of ice-melt and mechanical deicing, and wherein ice-melting mode is in power transmission line
So as to realize ice-melt, concrete mode has trend distribution formula ice-melt (in the short time increase power line load and heat production), short for upper heating
Road formula ice-melt (transmission line of electricity for being applied to three phase supply), high frequency pumping ice-melt (utilize the kelvin effect of high-frequency high-voltage, defeated
Resistance loss is caused to generate heat and ice-melt on electric wire), inevitably need to carry out certain journey to transmission line of electricity using ice-melting mode
The transformation of degree, and need to consume big energy and heated, deicing cost and difficulty are all higher；And mechanical deicing is mainly adopted
Carried out with the equipment being arranged on power transmission line, major way is using beaing, shake or blasting method is carried out, and its problem exists
In the general wind-force in power transmission line location is larger, and equipment is deflected by wind-force effect, it is difficult to operation is effectively carried out, and
Beat, shake by outside, the mode such as explosion is also difficult to smash ice sheet thicker on power transmission line so that deicing operation thing times work(
Half, it is difficult to produce a desired effect, need to fix blasting body on ice sheet in advance using blasting method, explosion uses outer quick-fried mode,
Deicing effect is limited and efficiency is low.
The content of the invention
The present invention is in order to solve above-mentioned problems of the prior art, and the invention provides a kind of transmission line of electricity spiral is quick-fried
