Abstract
The invention provides a rapid wiring conversion device for ice melting of a rural distribution power grid transmission line. The rapid wiring conversion device for the ice melting of the rural distribution power grid transmission line comprises a direct current ice melting module (1), wherein a positive electrode of the direct current ice melting module (1) is in parallel connection with two wiring sockets (2) with respective detachable wiring plugs (3) and a negative electrode of the direct current ice melting module (1) is in connection with a wiring socket (2) with a detachable wiring plug (3). According to the rapid wiring conversion device for the ice melting of the rural distribution power grid transmission line, three-phase ice melting can be achieved without manual wiring on the transmission line when icing is performed on the rural distribution power grid transmission line, so that the working efficiency of the ice melting is greatly improved and the safety hidden danger caused by the manual wiring is eliminated; the flexible change of three-phase series ice melting or parallel ice melting way is achieved; the labor intensity is reduced; the safety risk is reduced; and the length of an ice melting line is increased and the ice melting efficiency is improved.
Description
Technical field
The invention belongs to the electrical engineering technical field, relate in particular to a kind of fast-wiring conversion equipment for rural area dispensing grid power transmission line ice-melting, use this device when ice-melt, to implement conversion fast to improve the ice-melt operating efficiency to the transmission line wiring.
Background technology
In recent years, blocked up because of rural area dispensing grid power transmission circuit icing in winter, cause down the serious accident of bar, broken string to take place repeatedly.With in January, 2008 be example, occur in the electrical network ice damage that Hunan China is economized, cause a large amount of rural area dispensing power network lines to fall bar, broken string, direct economic loss reaches billions of yuans, and has had a strong impact on the masses' normal electricity consumption.Therefore, in transmission line formation icing, in time it is carried out ice-melt and handle, peel off or eliminate icing, prevent rupture of line and fall tower, guarantee that the safe operation of transmission line is very necessary.Yet the DC de-icing device that adopts only can be finished the two-phase ice-melt at every turn when ice-melt at present, and transmission line is generally three-phase, when implementing ice-melt at every turn, need carry out the reconfiguration lineman and do, workload is big, and has security risk during the reconfiguration line, and there is bigger threat in personal safety.
Summary of the invention
The technical problem to be solved in the present invention is, backward situation at prior art, design a kind of fast-wiring conversion equipment for rural area dispensing grid power transmission line ice-melting, when using this device to implement rural area dispensing grid power transmission line ice-melting, do not need to carry out traditional artificial wiring at transmission line, can realize the three-phase ice-melt at one stroke, improve the ice-melt operating efficiency greatly, eliminate the potential safety hazard that artificial wiring brings.
Technical scheme of the present invention is, above-mentioned designed a kind of fast-wiring conversion equipment for rural area dispensing grid power transmission line ice-melting, and shown in accompanying drawing 1, this device has a DC ice melting module 1.The positive pole of this DC ice melting module 1 is connected in parallel to two connector sockets 2 that have detachable connection plug 3 respectively; The negative pole of this DC ice melting module 1 is connected with a connector socket 2 that has detachable connection plug 3.
Operation principle of the present invention is: when rural area dispensing grid power transmission circuit icing, the DC ice melting module 1 of above-mentioned this fast-wiring conversion equipment for rural area dispensing grid power transmission line ice-melting provided by the invention is inserted external power supply, diesel generating set for example, with external power supply, for example the AC power of diesel generating set supply changes into DC power supply.Make two connector socket 2 positively chargeds that have detachable connection plug 3 respectively anodal in parallel with described DC ice melting module 1; And the connector socket that has detachable connection plug 32 that the negative pole of conveying described DC ice melting module 1 connects is electronegative.Then, respectively by lead, for example cable is connected to A phase, B phase, the C phase for the treatment of ice-melt rural area dispensing grid power transmission circuit with the detachable connection plug 3 of above-mentioned three connector sockets 2.According to on-the-spot ice-melt actual needs, can be with respectively with among three detachable connection plug 3 selectivity that the A phase, B phase, the C that treat ice-melt rural area dispensing grid power transmission circuit are connected be mutually inserted the jack of three connector sockets 2, thus implement flexibly two of transmission line ice-melting mode or two ice-melting mode that is in series that is in parallel that is in series.Come therefrom, this fast-wiring conversion equipment for rural area dispensing grid power transmission line ice-melting of the present invention, just can realize changing flexibly series connection ice-melting mode or the ice-melting mode in parallel of transmission line A phase, B phase, C phase three-phase, reaching does not need to carry out traditional artificial wiring at transmission line, can realize the three-phase ice-melt at one stroke, improve the ice-melt operating efficiency greatly, eliminate the purpose of the potential safety hazard that artificial wiring brings.
The invention has the beneficial effects as follows:
1) realized flexible change transmission line A phase, B phase, C three be in series ice-melting mode or ice-melting modes in parallel mutually, made that artificial wiring greatly reduces on the circuit of on-site conventional mode;
2) field personnel's labour intensity is reduced greatly, operating efficiency improves greatly;
3) avoid personal safety hidden danger under the freezing condition of sleet, greatly reduced security risk;
4) because the flexible change of ice-melting mode, but make the DC ice-melting length of rural area dispensing grid power transmission circuit increase greatly, promoted the application efficiency of ice-melt facility.
