The cable has the advantages of being sturdy and durable in use, not easy to damage, audio-visual in wire connection, short in assembly and connection time and good in process quality.
Description
Technical field
The utility model relates to a kind of electric energy metering secondary wiring, and a kind of specifically electric energy metering secondary private cable line belongs to electric power equipment technical field.
Background technology
In electric power system, electric power meter comprises that all kinds electric energy meter, metering are with voltage, current transformer and secondary circuit thereof, electric energy metrical cabinet (case) etc.The whether accurate vital interests that are directly connected between power supply enterprise and the power consumer of secondary circuit wiring wherein.(DL/T448-2000) stipulate according to " electric power meter technical management rules ": the connection lead of metering transformer secondary circuit should adopt copper single core insulation line; To electric current secondary loop, it connects sectional area of wire should be not less than 4mm at least
2To the voltage secondary circuit, connect sectional area of wire and should be not less than 2.5mm at least
2The secondary connection of current transformer should adopt the phase-splitting mode of connection, promptly should adopt six lines to be connected between its 3 secondary winding in current transformer and the electric energy meter; Voltage, each phase conductor of current circuit should adopt Huang, green, red line respectively, and the neutral line should adopt black line or blue line.In real work, we carry out in strict accordance with above-mentioned standard, but also meet some technical barriers, at first, because the sectional area in in-phase current loop and turnover line color are identical, cause in-phase current turnover line to connect instead easily.Through us the 2010 annual 163 family users' of our unit attaching investigation is found that wherein the secondary circuit error connection takes place 7 times altogether, and all does
In-phase current turnover line connects instead, and error connection causes measuring mistake easily; Secondly, attaching is consuming time longer relatively, secondary circuit attaching step and consuming time like Fig. 1, shown in 2.
Through statistics we to draw average each user of transformer secondary circuit attaching consuming time be about 53.7 minutes; The 3rd, attaching technology is relatively poor, through field investigation; We find in the on-the-spot attaching technology, in disorder, the intersection of the cabling of most of user's instrument transformer secondary line, even have part staff sense of responsibility not in place; Do not lie in attaching technology, only demand speed and do not ask processing quality.Therefore, the in-phase current reversed polarity takes place, the problem of secondary circuit attaching length consuming time and attaching processing quality difference in existing electric energy metering secondary attaching easily.
The utility model content
The technical problem that the utility model will solve and the technical assignment of proposition are the defectives that overcomes prior art, provide a kind of sturdy and durable, and not fragile, wiring is directly perceived, the electric energy metering secondary private cable line that attaching weak point consuming time and processing quality are good.For this reason, the utility model adopts following technical scheme.
A kind of electric energy metering secondary private cable line; Comprise complex root list core copper cash; It is characterized in that forming by single core copper cash of 64 square millimeters and 4 2.5 square millimeters; Distinguish with yellow, green, red and black color respectively, on the basis of native color, add different colour codes with single core copper cash of two 4 square millimeters of form and aspect and distinguish.General black and the blue scale of adopting distinguished.
The winding displacement rule of the utility model is: the centre is 4 2.5 square millimeters a pressure-wire, and both sides respectively are 34 square millimeters electric current line, arranges by yellow, green, red three kinds of colo(u)r breakup color separations respectively, and the outside is wrapped up in by the insulated cable suitcase, and inside is filled by nylon.Make cable internal copper heart yearn fasteningly have certain pliability again like this, the cable outside is sturdy and durable, and is not fragile.
The wiring rules of the utility model: homochromy phase current tape black colour code connects current transformer S1 end, and the current transformer S2 that connects of band blue scale holds, and all the other wiring rules are constant.
The scope of application: this electric energy metrical private cable line is applicable to that mainly the height that inserts through current transformer supplies low meter and hang down to supply low meter user.
Attaching step: behind the utilization electric energy metering secondary private cable line; Step to binding and cabling is optimized; Need when the attaching of routine, that kind not carry out the layering color separation and tie up 4 voltages, 6 electric current list core copper cores; When cabling, can not cause secondary line to intersect yet, optimize the attaching step of secondary circuit.
Secondary circuit attaching is in the past compared; Because adopted the technical scheme of the utility model, the wiring of each terminal of electric energy metering secondary is more directly perceived, has stopped the phenomenon of in-phase current reversed polarity; After secondary circuit attaching step is optimized; Effectively avoid loaded down with trivial details binding and wiring, significantly reduced the attaching time, improved the attaching processing quality.
The electric energy metering secondary private cable line of the utility model has shortened the on-the-spot attaching time, has reduced personnel labor, in the summer and the cold winter of sweltering heat, the staff has been played very big help especially, has broken attaching thinking in the past.Simultaneously, the mistake of electric power meter secondary connection has effectively been avoided in the development of electric energy metrical private cable, has stopped the hidden danger of secondary circuit error connection from the source.Further, the development of electric energy metering secondary private cable effectively raises the technological level of electric energy metering secondary wiring, and secondary line is wrapped up by cable sheath, has reduced the damage of secondary line.For the user of cancellation, the secondary line of tearing open is back all regarded the waste and old material processing, but the secondary cable line of now tearing open back can also reuse, and has embodied State Grid Corporation of China's " three practice thrift " theme in the past.At last; The development of electric energy metering secondary private cable line is that personnel such as power utility check do not have a power failure at the scene and do not use under the situation of any aid; Whether correct to the wiring of electric power meter secondary circuit, just can make right judgement with visual, made things convenient for the power utility check personnel.
