Abstract
The utility model discloses an ice-coating proof hollow ventilating transmission conducting wire. A traction layer and a conducting layer are alternately coated outside a ventilating tube in sequence. The ventilating tube is a metal soft tube. The traction layer is formed by winding of a traction wire in a right-handed screw mode. The conducting layer is formed by winding of a traction wire in a left-hand screw mode. Compared with the prior art, due to the fact that the ventilating tube and a hollow conducting wire are arranged in the transmission conducting wire, the ice-coating proof hollow ventilating transmission conducting wire has the advantages that when flowing hot air is sustainably supplied to the inner portion of the transmission conducting wire, the temperature of the transmission conducting wire is always above zero DEG C, snow and ice cannot be attached to the conducting wire, and the safety of the transmission device is guaranteed.
Description
Technical field
The utility model belongs to the electric power conveying equipment, is specifically related to a kind of transmission pressure that can prevent from producing icing under cryogenic conditions.
Background technology
Along with Chinese economic development, the progress of society, electric power plays crucial effects in all trades and professions and people's life.Society impels country to drop into substantial contribution at power grid construction to the demand of electric energy, by the high pressure in past to superhigh pressure, ultra high voltage development, by the section electrical network in past to the key power network development that crosses some provinces.This causes transmission pressure to reach thousands of kilometer, and what have also needs to pass through high height above sea level, extremely frigid zones, and particularly in the winter time, the situation that often has icing on the lead to damage electric power pylon by pressure takes place.Wire fracture, iron tower collapse, and lead to a disaster, and have a strong impact on the resident's of electric terminal life, and the normal operation that influences enterprise.
Current, the method for anti-snow and ice both domestic and external mainly contains thermal ice-melting, mechanical deicing and mode such as deices naturally, and its execution mode mainly contains the short circuit ice-melt, transfers negative ice-melt, direct current ice-melt and capacitance compensation inductance to transfer negative ice-melt etc.But, no matter adopt what mode ice-melt, all be on a lead or many leads, to carry out simultaneously, that is, do not have the lead of snowberg or ice can together heat up yet, cause energy waste, be unfavorable for the normal operation of equipment, have in addition need transmission line have a power failure to cooperate snow melt, ice.Simultaneously, these method many places except snow and ice, when a large amount of snow of lead or ice separate with lead, the lead high vibration can occur in passive, destroy power transmission facility.Therefore, improving the snow defence of transmission line self and the ability of ice is very to be necessary.
Summary of the invention
Given this, the utility model purpose is to provide a kind of ice-covering-proof hollow ventilation lead.
For solving above technical problem, the technical scheme that the utility model provides is, a kind of transmission pressure is provided, alternating packets is covered with traction layer and conductive layer successively outside breather pipe, described breather pipe is metal hose, described traction layer is to be formed by the mode coiling of draught line by right-handed helix, and described conductive layer is to be formed by the mode coiling of lead by left hand helix.
Further, described metal hose is to be formed by the mode coiling of a bonding jumper with certain-length by left hand helix, this bonding jumper comprises two faying faces, a faying face is provided with groove, another faying face is provided with raised line, bonding jumper is behind a circle, and the raised line of a last ring inserts in the groove of next ring.
Preferably, described lead is hollow conductor.
Further, described conductive layer is at least one deck.
Preferably, the number of plies of described traction layer equates with conductive layer or many one decks.
Compared with prior art, transmission pressure provided by the utility model has overcome deficiency of the prior art, and it has following characteristics:
1, breather pipe is the helix tube that is formed by the mode coiling of bonding jumper by left hand helix, and this bonding jumper is selected steel bar for use.Breather pipe can play transmission pressure sectional area maintenance effect.Simultaneously, under external force, air is mobile in breather pipe, meanwhile, air and breather pipe generation heat exchange, breather pipe transfers heat to draught line and lead again, under cold environment, improves the temperature of lead, makes lead be difficult for producing icing.The design of helix tube when lead is crooked, can guarantee that caliber can not change at breather pipe, can also be simultaneously that helix tube keeps good air-tightness.
2, draught line can be made by steel material, can carry all loads of whole piece transmission pressure.Simultaneously, draught line can also protect the structure of breather pipe not to be destroyed, and that is to say, when laying this transmission pressure, two faying faces of fitting mutually of breather pipe can be because of being fully withdrawn under external force.
3, lead is made by the less electric conducting material of resistivity, and this lead can use solid conductor, also can use hollow conductor.Certainly, preferably select hollow conductor for use, where necessary, can be directly in the hollow conductor bubbling air, make air and the lead of band heat directly carry out heat exchange, ice-covering-proof better effects if.
4, this transmission pressure continues to provide to its inside when flowing hot-air owing to have breather pipe and hollow conductor, and the temperature of transmission pressure is in above zero all the time, and snow just can't adhere at lead with ice, has also just guaranteed the safety of transmission facility.
5, the breather pipe in this transmission pressure is opposite with the hand of spiral of traction layer, can prevent situation about being absorbed in, and influences overall structure and the performance of transmission pressure, and traction layer is also opposite with the hand of spiral of conductive layer, and it acts on, and the former is identical.
6, in addition, traction layer and conductive layer can be set to one or more layers as required, it should be noted that between the adjacent two layers around on the contrary.
