Abstract
The utility model relates to high voltage power distribution equipment, in particular to a connection device for a high voltage cable. A conversion device for a single-phase cable core of the high voltage cable comprises a copper bar and branch copper bars located on two sides of the copper bar, wherein wiring terminals are connected at both ends of each branch copper bar. The conversion device further comprises a connection bar or branch connection sections, wherein insulation layers based on corresponding voltage class requirements are covered on the branch connection sections, and two ends of each conversion device are connected in the same phase. The conversion device for the single-phase cable core of the high voltage cable can reduce cost, is flexible and convenient in construction, and improves stability of a high voltage power distribution system.
Description
Technical field
The utility model relates to the high pressure power supplying and distributing equipment, relates in particular to a kind of jockey of high-tension cable.
Background technology
In the town road electric power system; The long-distance cable transmission of electricity is generally high voltage supply system, because circuit is longer, and supply load and dispersion thereof; Need on Voltage Cable Lines Construction, carry out tap; Common solution of past is on the center-aisle of cable laying, to increase high-tension distribution box or adopt the secondary terminal head to carry out tap, first kind of increase of adopting high-tension distribution box the engineering maintenance cost, and the distribution box transmission of electricity has increased input; Second kind is adopted secondary terminal head tap mode, owing on a terminal, connect a plurality of terminals, causes the terminals loose contact easily, the easy burn-out terminals, even cause fire incident.
In industrial power distribution systems, the normal because binding post configuration of distribution board cabinet does not match with the cable of design, makes the service cable can't wiring, needs to adopt the cable of different model to carry out wiring, these two kinds of model cables since core specifications and models difference need connect.Directly be connected on the terminal unmatched cable is rigid generally speaking, be prone to produce the fault on the equipment operation.
Summary of the invention
The utility model is intended to address the above problem, and a kind of high-tension cable core conversion equipment is provided.The utility model can reduce cost, and it is flexible to construct, and improves the stability of high pressure delivery electric system.
For addressing the above problem; The single-phase core conversion equipment of a kind of high-tension cable; It comprises a copper rod and the branch's copper rod that is positioned at the copper rod both sides; This branch copper rod end all is connected with binding post, and transducer also comprises on pitman and the branch's linkage section should cover the insulating barrier according to the relevant voltage class requirement, each transducer two ends be connected same mutually in.
The single-phase core conversion equipment of described high-tension cable, said copper rod and branch copper rod are all according to the residing sheath that is provided with corresponding color mutually of conversion equipment.
The conversion equipment core of the utility model is made up of the branch on a copper rod and copper rod both sides thereof; Can confirm the quantity of copper rod both sides branch according to the requirement in requirement of client or actual the use; Copper rod both sides branch splicing ear, the terminal specification is confirmed according to line cord voltage by GB; The insulation of high-tension cable core transducer copper rod is confirmed by the use line voltage distribution.The utility model has solved the high-tension cable long distance powedr transmission interim branch of required halfway increase and need not increase the situation of the equipment that height is press-fitted, and has both practiced thrift construction investment, also reduces engineering maintenance, maintenance cost; The situation that has also solved in the high pressure long distance powedr transmission way two power cables the need that are difficult to wiring are set up interim high-tension distribution equipment because the core wiring does not match; Present technique is practiced thrift construction investment, increased simultaneously engineering construction particularly in emergency circumstances power-on time the high-tension cable specification is substituted the flexibility that requires; The utility model has also solved high pressure power supplying and distributing equipment cabinet internal wiring terminal the not matching property of cable to the high voltage power transmission that disposed in addition, and promptly the high voltage supply cable is because the limited problem that is difficult to wiring in space in the feeding pannel cabinet.
Description of drawings
Below, in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model sketch map.
Embodiment
The utility model is the single-phase core conversion equipment of high-tension cable; Change three-way or three-way commentaries on classics two wires single phase converter like Fig. 1 for the two wires; Three phase converer then is made up of such three same conversion equipments; Be three of the ABC that treat power supply with a certain discrimination, can the color that every transducer outermost layer insulated hull of power supply is mutually painted corresponding ABC phase GB regulation be got final product, can be during physical cabling according to the truth wiring of every phase of wiring.
Conversion equipment shown in Figure 1 is made up of five binding posts; Be five binding posts 2,3, No. 4 among the figure; Binding post all is connected on the copper rod 1; Binding post 2,3,4 and copper rod 1, the rated voltage that can in current supply circuit, use according to transducer, the difference of rated current increase the insulating barrier of different size model.This specification provides 2 lines to change 3 lines, or 3 lines are changed the single-phase conversion equipment of 2 lines.Service cable is connected on the both sides of copper rod 1 respectively.Copper rod both sides design terminal is different because supply current is different.The terminal of transducer directly is connected on the required conversion high-voltgae pothead, carry out every unit cable head plastic packaging then, and the class of insulation of plastic packaging must reach the GB requirement.
Claims (2)
1. single-phase core conversion equipment of high-tension cable; It is characterized in that; It comprises a copper rod and the branch's copper rod that is positioned at the copper rod both sides; This branch copper rod end all is connected with binding post, and transducer also comprises on pitman and the branch's linkage section should cover the insulating barrier according to the relevant voltage class requirement, each transducer be connected same mutually in.
2. the single-phase core conversion equipment of high-tension cable according to claim 1 is characterized in that, said copper rod and branch copper rod are all according to the residing sheath that is provided with corresponding color mutually of conversion equipment.
