Description

A kind of power circuit is anti-to wave ice removal

Technical field

This utility model belongs to wire icing removal tool and removes icing method and technology field with the instrument, especially relates to And a kind of power circuit is anti-waves ice removal.

Background technology

In January, 2008, China Central China, East China, southern most area occur in that the rare low temperature sleet and snow ice day of history Gas, causes power transformating and supplying facility large area icing, and generally more than 30 millimeters, some areas reach 80 millimeters to ice covering thickness, cause defeated Electric line breaks in a large number, and electric power facility is damaged on a large scale, and electric network composition is seriously damaged.From 1980 to 2007, the whole nation Up to 2,109,700,000,000 yuan, installed capacity and generated energy have leapt to second place of the world to electric generation investment total value, and power system is also into regarding it as For person of outstanding talent Large Copacity, large-sized unit, high parameter, extra-high voltage, long distance powedr transmission new stage.But, this huge system is at this But show so fragile in face of the precipitate ice disaster in field, unbearably tackle:Youngster 100,000 electric poles, towers collapse, and transport to bar High pressure, extra high voltage network interrupt, and distant place power supply base cannot be sent, and large power plant cannot access system forced outage;It is lonely Network operation, the little net of big machine, Large Copacity, high pressure high temperature turbosets are of no avail, and high-capacity direct current cannot feed-in;In Receiving End Load The heart, Main Towns non-transformer are supported.Therefore, should strengthen to the anti-icing of transmission line of electricity, clearing ice technology research.

At present, removing ice of power transmission line, reduction loss are a technical barriers.The thinking of network system deicing can divide three substantially Class:

(1) heating power method:Convert electrical energy into the heating power method of heat energy ice-melt;Heating power method makes the maximally effective deicing of world workman Technology, using Joule effect ice-melt principle, using electric current heating ice coating wire deicing is carried out.Typical heating power de-icing method has Japan's resistive magnet wires developed in 1987 and the low Curie's magnetic hot line developed by Wuhan High Voltage Research Institute for 1988.Heating power method It is divided into again:

1) transferring load method.This method is increased without any equipment, by the structure for changing electrical network, using load current Heat effect preventing conductor glaze formation or deicing.

2) short-circuit method.Short-circuit method refers to another terminal shortcircuit by power supplying from one direction, so that line load increase carries out ice-melt.

3) ac and dc current method.Great number surcharge is not needed using alternating current, because it is directly carried out using existing network Ice-melt, particularly to long distance transmission line.But in order to obtain necessary ice melting current, it is necessary to have sufficiently high ice-melt voltage and Corresponding ice-melt power.Heating power method deicing effect is obvious, but energy loss is big, and equipment investment cost is high, and the scope of application is less, This kind of method is in electric power energy today in short supply and China vast in territory and is not suitable for using.

(2) Mechanical Method:The icing physical arrangement that converts electrical energy into mechanical energy to destroy on power transmission line simultaneously makes it come off, and reaches To deicing purpose.Mechanical deicing send out be directly using across knife, rod, cylinder, cutting machine, use projectile, automatization at a distance Robot, shock wave Mechanical Method, using modes such as blast, bending, stubborn stricture of vaginas deicing is carried out, and mechanical means crush one piece of given size Ice required for energy simply melt ten a ten thousandths even 200 a ten thousandths of energy needed for this ice cube, it is actually various Between 3% to 4%, totally apparently, mechanical means only need energy needed for thermal methods to the energy efficiency scope of mechanical deicing's technology 1/200 or so.There are armstrong's patent deicing and automation deicing suitable for mechanical deicing's method of transmission line of electricity at present.

There is surface personnel to pull the cunning that can be walked on the line during the pulley spatula for being proposed by Canada for 1993 Wheel reaches product

Go out the purpose of icing.The method is not particularly suited for the western high hypo of China, region with a varied topography.

(3) passive means：Without the need for additional-energy deicing, by deicing such as wind, terrestrial gravitation, random scatter and temperature changes Passive approach, without the need for additional-energy.What existing own Jing was applied on transmission line of electricity has counterpoise, wire clamp, deicing ring, resistance snow Ring, hydrophobic coating, air-leg etc. install stockbridge damper etc. to reduce waving for wire reducing the icing of transmission line of electricity.Passive means Have the advantages that expense is low, but the formation of icing can not be prevented, and be only applicable to specific area.In addition to above-mentioned several method, Also freezed using electromagnetic pulse, air pulsing, corona discharge, electronics, collide front granule heating and freeze, in test rank Section.
