Abstract
The invention provides an anti-icing and deicing method for a power line by using an inflatable airbag anti-icing protective belt which has a simple and rational structure and is convenient to mount/dismount. The anti-icing protective belt provided by the method is formed by covering up an airbag with flame retarding insulating elastic fibre cloth and then sewing; the airbag is made from a material similar to a natural rubber inner tube of a motorcycle and made by a process similar to manufacture the natural rubber inner tube of the motorcycle; a manner of locking by a zip fastener or tightening by a tightening strip is adopted in the method for covering up leads and tower materials by the protective belt; specifications of the protective belts are different according to the different sizes of the covered lead and covered equipment materials; and the naked layer of the protective belt is covered with an anti-icing paint which is beneficial to deicing the external layer of the protective belt. The procedure of realizing the method comprises the steps of: introducing different air pressures to the airbag of the protective belt covering the lead or equipment materials of the power line, wherein the adjustment of the air pressure is realized by introducing different air pressures in the control of a switch according to the on-site conditions observed by inspectors; expanding and cracking an ice layer on the surface of the protective belt by the expansion force of the airbag protective belt, and making the ice layer fall off naturally in the action of gravity so as to play a role in deicing.
Description
Technical field
This method relates to a kind of power circuit ice control, specifically is a kind of power circuit anti-icing and deicing method.
Background technology
Because abominable ice storm weather causes powerline ice-covering to increase the weight of and the bar that breaks down, thereby causes large-area power-cuts, this phenomenon happens occasionally in China.Ice damage in 2008 has all caused heavy losses for the electric power transmission line of southern most laboratories.The present ice control of electric power transmission line divides anti-icing and deices two classes, be negative means and mechanical means, negative means promptly adopts hates ice coating, and antiicing coating commonly used has: polytetrafluoroethylene, fluorinated ethylene propylene (FEP), grease and oils, salt adhesive layer etc. utilizes natural force to prevent that accumulated ice and promotion from deicing; Mechanical means is deicing apparatus and the anti-icing equipment that relies on extra power, and mode commonly used has: adopt steam, oscillator, steel brush, induction coil, haulage chain on lead, and adopt extreme load electric current etc.For now, an effective and economic method that prevents powerline ice-covering is not arranged also, in case the perhaps good mode of corresponding removing accumulated ice behind the icing.
Summary of the invention
This method technical issues that need to address are, overcome disadvantages of background technology, provide a kind of simple and reasonable, the power circuit de-icing method of the anti-icing boundary belt of air bag of easy accessibility.The anti-icing boundary belt of this method is wrapped to make behind the air bag by fire-retardant warming fiber elastic cloth and forms; air bag adopts the material and the technology that are similar to the motorcycle natural gum inner tube of a tyre to make; the specification of boundary belt will be different according to lead that is wrapped up and the difference of equipment and materials size, and the boundary belt exposed layer adopts antiicing coating to be beneficial to the boundary belt skin and deices.Pass to (the adjustment of air pressure of different air pressure by the air bag of wrapping for protected band; can be by the floor manager according to field condition; realize by adjusting the different air pressure of input); thereby spalling was attached to freezing of boundary belt top layer after the anti-icing boundary belt of the air bag that wraps line conductor and power equipment material was expanded; effect by gravity comes off it naturally, to play except that ice action.
Technical scheme
This method solves the technical scheme that its technical problem adopts:
First; the implementation procedure of the anti-icing technology of the anti-icing boundary belt of air bag is: when the power circuit location eternal frost climate line conductor material occurs and freezes; by feeding air pressure for the air bag in the boundary belt; spalling was attached to freezing of boundary belt top layer after the anti-icing boundary belt of the air bag that wraps power line lead or other electric equipment material was expanded; effect by gravity comes off it naturally, to play except that ice action.
Second; the required air pressure of the anti-icing boundary belt of air bag is supplied by special-purpose air compressor plant; the air compressor machine operating pressure selects for use 7/8/10Mpa, air displacement to select for use 5.0/4.6/4.1 cube/minute, power to be the air compressor machine of 30Kw and to be equipped with dried-air drier, the required power supply of air compressor machine take from transmission line through the area nearby the special-purpose distribution transformer of 10kv distribution line.The setting of air compressor plant is installed one by≤6km configuration, by the insulation tracheae from air compression station behind source of the gas distributor on the overhead line structures, respectively to the air bag boundary belt air feed of the about 3 kilometers long line conductors in circuit both sides and lead suspension insulator and conductor spacer.
The 3rd, every phase power circuit air bag boundary belt makes the insulation tracheae not relate to the high voltage technique problem that need bear power line route voltage respectively by the tracheae air feed that independently insulate.
The 4th, be input to the compressed air in the anti-icing boundary belt of air bag, need to make dry filter and handle, in case humid air freezes in tracheae and air bag through air dry filter machine.
The 5th, the anti-icing boundary belt of shaft tower air bag is only installed the about 1/3 shaft tower height of protection shaft tower epimere, and the shaft tower hypomere does not consider to take special safeguard measure.
The 6th, the anti-icing boundary belt of power circuit air bag drops in the late December in every year and installs and uses, and removes the mid-March of next year and withdraws from use, so need not consider to take special lightning-protection engineering.
