Description
Technical field
The utility model relates to a kind of removing ice of power transmission line instrument, especially a kind of ultra-high-tension power transmission line mechanical deicing device.
Background technology
The icing of overhead transmission line is in early winter and time in the early spring (temperature is-5 DEG C of left and right), or in snowfall or the weather that snows with a mingling of rain, locate all to have ice, frost and snow slush at the wire of overhead transmission line, lightning conducter, insulator string etc. and be mixed to form bent ice sheet.This is the solid and transparent or semitransparent ice sheet closely of one deck, forms the reason of hat ice sheet, is owing to adhering to water droplet on nature object, and in the time of mercury dropped, these water droplets just congeal into ice, and more knot is thicker.Too much when built on stilts electric line ice and snow, while there is serious icing on line conductor, lightning conducter, be first the mechanical load that increases the weight of wire and shaft tower, conducting wire sag is too increased, thereby cause swinging cross or broken string; In the time of coating ice falling on wire, lightning conducter, can make again wire, lightning conducter generation chattering, thereby cause swinging cross accident.In addition, too much owing to gathering ice and snow on porcelain vase or cross-arm, and then cause the flashover fault of insulator.
The icing of wire and lightning conducter is very thick sometimes, defined loading can exceed designed lines when serious time.If also attend by high wind when wire, lightning conducter generation icing, its loading more will increase, and this may cause wire or lightning conducter broken string, and gold utensil and insulator string are destroyed, and even makes shaft tower damage.Especially fan-shaped icing, it can make wire twist, so threaten maximum to gold utensil and insulator string.
Method and the pluses and minuses of tradition deicing:
1, electric current melts method:
Increase line load electric current with changing the operational mode of power network; Circuit and system are disconnected, and one end three-phase shortcircuit of circuit is got up, the other end is supplied with short circuit current with ad hoc transformer or generator.In the time adopting increase line load electric current to carry out the way of heating wires, the initial stage that should start to form at icing strengthens load current, as precautionary measures.But this way can make lower voltage, the increase electric energy loss of circuit, so can not use for a long time.In the time melting icing with short-circuit method, should be according to line length, the cross section of wire and material, necessary equipment is got in Huaihe River ready, and its capacity should be computed in advance, enables to meet the requirement of ice melting.
During by short circuit current ice melting, had better not use the ground network of power plant and electric substation, and adopt independent earthing device, to avoid danger.When Yong Duan road electricity stream Rong ice, the fusion process of removing to observe icing on the circuit of also should sending someone, when icing has started when wire comes off, should cut off immediately ice melting current, otherwise the time one to be long, can make wire overheated, should note especially the junction of wire.Under general appointed condition, electric current melting ice method is to be difficult to realize, and therefore, except heavy icing area, its practical value is little.
2, mechanical deicing's method:
Mechanical deicing mainly adopts following several way:
1) guiding line or the short waddy of lightning conducter throwing from ground, smash icing, makes it to come off.Also can put to grab with rod or bamboo pole and make coating ice falling.If line outage difficulty also can be beaten icing with insulating bar;
2) be enclosed within on wire with wooden lasso, and draw along wire with rope, just can eliminate icing;
3) carry out deicing with pulley type ice removal.
Mechanical deicing's method is more original, and the mechanical deicing of ultra-high-tension power transmission line must climb up on steel tower and wire and could implement by electrical employee, serious harm electric power worker's personal safety.The pattern each department of ice removal are not identical yet, and its kind is a lot.Mechanical deicing's method major defect is must have a power failure and carry out, time-consuming, effort.And be not easy to ensure that any mechanical failure does not occur for wire and lightning conducter.
