Abstract
The invention relates to an insulated wire connecting method for setting up a middle and low voltage overhead power line, and belongs to the technical field of middle and low voltage overhead power lines. The technical scheme is that the outer insulating layers of insulated wires are added with pigments in three colors of yellow, green, and red, and the outer insulating layers of produced insulated wires are in three colors of yellow, green, and red, according to a phase sequence that the three colors of yellow, green, and red of the outer insulating layers of insulated wires are respectively corresponding to three phases of A, B, and C, laying the insulated wires (4) in sequence on a concrete rod (3); when an insulated wire connecting point a (5) and an insulated wire connecting point b (6) in the same color occur, connecting the insulated wires in the same color, so as to complete connection of insulated wires and prevent wrong connection of phase sequence. Beneficial effects of the method are that on the premise that electrical properties of insulation and strength of insulated wires are not affected, the method can rapidly distinguish phase sequence, provides convenience for connection, and the wires would not be connected in a wrong way, and in circuit patrol, the method can rapidly find out fault points.
Description
Technical field
The present invention relates to a kind of insulated wire method of attachment of setting up mesolow overhead power line, belong to mesolow overhead power line technical field.
Background technology
Along with the development of line insulation, the plain conductor of mesolow overhead power line is replaced by insulated wire gradually, the insulation sheath of insulated wire is generally black, three wires of overhead power line, be divided into ABC three-phase, according to " overhead distribution and equipment operating standard " regulation, the three-phase of wire uses Huang, green, red trichromatism mark respectively.Three wires, when there is joint, because insulation sheath is single black, can not be differentiated fast, easily occur the wire wrong of different phase sequence, affect efficiency of construction and quality when connecting.In addition, running under line accident trip condition, when carrying out circuit inspection, the personnel that make an inspection tour are difficult to distinguish phase sequence, can not carry out line inspection targetedly, can not be out of order a little by fast finding.
Summary of the invention
The object of this invention is to provide a kind of insulated wire method of attachment of setting up mesolow overhead power line, under the electricity characteristic prerequisite such as insulation, intensity not affecting insulated wire, phase sequence can be differentiated fast, convenient to connect, can not wire wrong; When carrying out circuit inspection, can be out of order a little by fast finding, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is:
Set up a method of attachment for the insulated wire of mesolow overhead power line, comprise following processing step:
insulated wire is made up of electric conductor and external insulation layer, and when producing insulated wire, in the external insulation layer of insulated wire, add the pigment of yellowish green red three colors respectively, the external insulation layer of the insulated wire produced is divided into yellowish green red three colors;
When 2. setting up mesolow overhead power line, according to A, B, C three-phase phase-sequence of the corresponding mesolow overhead power line of yellowish green red three colors difference of insulated wire external insulation layer, order carries out insulated wire unfolding on concrete bar;
3., in unfolding process, when there is insulated wire tie point a and the insulated wire tie point b of same color, only need the insulated wire of same color to connect, complete the connection of insulated wire, avoid phase sequence wrong;
when running into line accident trip condition, the personnel that make an inspection tour, according to traffic department's order, directly distinguish phase sequence according to circuit color and carry out line inspection, looking up the fault point.
Good effect of the present invention is: under the electricity characteristic prerequisite such as insulation, intensity not affecting insulated wire, can differentiate phase sequence fast, and convenient connection, can not by wire wrong; When carrying out circuit inspection, can be out of order a little by fast finding.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention insulated wire structural representation;
Fig. 2 is embodiment of the present invention schematic diagram;
In figure: electric conductor 1, external insulation layer 2, concrete bar 3, insulated wire 4, insulated wire tie point a5, insulated wire tie point b6.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention will be further described.
Set up a method of attachment for the insulated wire of mesolow overhead power line, comprise following processing step:
insulated wire is made up of electric conductor 1 and external insulation layer 2, and when producing insulated wire, in the external insulation layer of insulated wire, add the pigment of yellowish green red three colors respectively, the external insulation layer of the insulated wire produced is divided into yellowish green red three colors;
When 2. setting up mesolow overhead power line, according to A, B, C three-phase phase-sequence of the corresponding mesolow overhead power line of yellowish green red three colors difference of insulated wire external insulation layer 2, order is carried out insulated wire 4 and is unfolded on concrete bar 3;
3., in unfolding process, when there is insulated wire tie point a5 and the insulated wire tie point b6 of same color, only need the insulated wire of same color to connect, complete the connection of insulated wire, avoid phase sequence wrong;
when running into line accident trip condition, the personnel that make an inspection tour, according to traffic department's order, directly distinguish phase sequence according to circuit color and carry out line inspection, looking up the fault point.
The insulated wire tie point a5 of described same color and insulated wire tie point b6, be the insulated wire end points on different concrete bar 3, the insulated wire of same phase links together, overall formation mesolow overhead power line.
The present invention, not affecting under the electricity characteristic prerequisites such as the insulation of insulated wire, intensity, can differentiate phase sequence fast, convenient connects, can not wire wrong; When carrying out circuit inspection, can be out of order a little by fast finding.
