Abstract

The invention relates to a deicing power transmission line of multiple conducting wires. Multiple (more than two but less than four) power transmission lines arranged in parallel in the same direction form a line set, wherein the lines are mutually separated and arranged in zones. Conducting wires at two ends of each line set of each zone are connected with a breaker respectively, and the breakers at two ends of each zone are communicated. Under normal condition, all breakers at two ends of each line set of each zone are switched on and powered, and the conducting wires do not heat. Once the conducting wires are iced heavily, when a section of the conducting wire needs to deice, one line in the breaker at any end of the line set is reserved, and the rest lines are switched off and not powered. Thus, only one conducting wire is switched on and powered to bear overall electric quantity of the line set, the current is increased and the line heats, and then the line melts ice so as to deice. In the same way, when the breaker is transformed, any conducting wire can melt the ice. When the ice is melted, the normal condition recovers.

Description

The deicing power transmission line of multiple conducting wires

Affiliated technical field

The present invention relates to the deicing power transmission line of a kind of transmission line, particularly multiple conducting wires.

Background technology

Existing transmission line does not have de-icing method and equipment easily.Coagulate weather and sleet in case run into lasting snow, electric wire freezes, and weight increases, and forgets about it iron tower, forgets about it electric pole, breaks electric wire, causes large-area power-cuts, suffers heavy losses.A kind of technology is arranged " deicing power transmission line ", number of patent application 200820062242.3 is that each root power transmission line is divided into two parts, and a part is many, is leeched line, and a part is few, is industrial siding, with insulating barrier industrial siding is coated.Again the two coil buckling is become a lead.At ordinary times, industrial siding and leeched line are all switched on, and lead does not generate heat.During deicing, the disconnection of operating a switch of leeched line switch, only with the industrial siding energising, the industrial siding electric current increases and generates heat, and makes ice dissolve deicing.This method deicing totally, thoroughly, also convenient, but for the multiple conducting wires of now having installed (many identical live wires), just not too convenient.Because it will all separate a lead, insulate, coil buckling will increase cost together economically again.

Summary of the invention

The present invention has taked new method for the deficiency that overcomes said method.This method is: one, divide section to install.Two, change wiring, divide section control.In each section by the parallel installation of multiple conducting wires, to call the line group in the following text.Distance is near between the lead, separate with insulating support, distance, do not add support.Each root lead of each each line group of section two ends all is connected with separately breaker, and each breaker of each section is connected together.Under the normal condition, the breaker of every line of each line group of each section all closes a floodgate, every line is all switched on, lead does not show heating, in case conductor glaze formation is thicker, when needing deicing, the any end in this section line group two ends is stayed beyond lead switch closes a floodgate, all the other disconnection no powers of all operating a switch, this root current in wire of switching on increases and generates heat, and ice is dissolved.The change over switch lock, deicing in turn can make the deicing of whole piece circuit.Deicing finishes, and recovers normal again.

Description of drawings

Accompanying drawing is the connecting and disconnecting schematic diagram of each the end of a thread of explanation and breaker.In the accompanying drawing, lead 1, left-handed opening lock 2, right breaker 3.Each root lead of left side bearing group all links to each other with left-handed opening lock 2 contact connector lugs, and each root lead of right side bearing group all links to each other with right breaker contact connector lug, and left-handed opening lock 2 and right breaker 3 are connected.

Specific embodiments

Under the normal condition, as above figure, the energising of all closing a floodgate of the breaker of the left and right sides each root lead of line group.Every lead carries all energising amounts of this line group jointly.Lead does not show heating.In case conductor glaze formation is thicker, when needing deicing, as figure below, it is the energising of closing a floodgate that the left side bearing group has only the breaker of a lead, all the other several disconnections of operating a switch entirely, no power.So the left side has only whole energising amounts of this line group of that wires carry.So this root current in wire increases and generates heat, ice is dissolved and deicing.Change each line group, each section breaker, can make the deicing of whole piece circuit.

The new circuit of installing, general 2 to 4 is a line group.

Each root lead of each line group can be to form one by multiple conducting wires (comprising steel core) coil buckling, also can be solid conductor.Each section according to circumstances can be tens meters, hundreds of rice to tens kilometer, in addition farther.On the main line, be at least one or several section between each transformation station, per two should be a section between the user of wiring on the main line.

Claims

1. the deicing power transmission line of multiple conducting wires is formed the line group by multiple conducting wires, constitutes circuit by line group and control switch lock, it is characterized in that:

(1). whole line sectionalizing is installed, the segmentation deicing;
