Abstract
The invention relates to high-voltage power supply and distribution, and in particular relates to a method for converting high-voltage cables. A high-voltage cable core converting method is adopted between the cables to be converted and comprises the following steps of: 1, making a converter, wherein the converter comprises a main connecting bar and an insulating layer, each of two ends of the main connecting bar is provided with at least one branched connecting section, a connecting terminal is arranged at each of the tail end of each branched connecting section and two ends of the main connecting bar, and the insulating layer is covered on the connecting bar or the branched connecting sections according to the corresponding voltage level requirement; 2, respectively connecting the connecting terminals at two ends of the converter made in the step 1 to two sections of cables to be converted; and 3, performing insulated plastic package on each single cable head. By the method, conversion and middle tapping of the high-voltage cables can be conveniently, safely and quickly realized.
Description
Technical field
The present invention relates to high pressure for distribution, relate in particular to conversion three methods between the high voltage 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 to carry out tap in Voltage Cable Lines Construction, common solution of past is to increase high-tension distribution box or adopt the secondary terminal head to carry out tap at the center-aisle of cable laying, the first adopt high-tension distribution box increase the engineering maintenance cost, and the distribution box transmission of electricity has increased input; The second adopts secondary terminal head tap mode, owing to connecting a plurality of terminals at a terminal, easily causes the terminals loose contact, the easy burn-out terminals, even cause fire incident;
In industrial power distribution systems, the normal because binding post configuration of distribution board cabinet is not mated 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.Do not adopt generally speaking this transition cable to connect, directly be connected on the terminal unmatched cable is rigid, easily the fault in the operation of generation equipment.
Because the terminals that high-tension cable connects usually are higher to insulating requirements, when directly docking two terminals, the thicker insulating barrier in the end after terminals complete to do sufficient electrical connection, easily produce the gap, like this, the contact resistance of this end points is higher, easily heating in the running, thus easy burn-out docking terminal produces equipment fault.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and a kind of high voltage cable core conversion method is provided.The present invention can make things convenient for, realize safely and fast conversion and the centre tap of high voltage cable.
For addressing the above problem, a kind of high voltage cable core conversion method, it is arranged between the cable to be converted, and it comprises the following steps:
Step 1, transducer is made, and this transducer comprises a main pitman, and these main pitman two ends are with at least two branch's linkage sections, branch's linkage section end is provided with splicing ear, and transducer also comprises the insulating barrier that should cover on pitman and the branch's linkage section according to the relevant voltage class requirement;
Step 3 is to every unit cable head plastic packaging that insulate.
Described high voltage cable core conversion method, described step 2 comprise each phase high voltage cable all with one and above transducer connection.
The described step 1 of described high voltage cable core conversion method also is included in the coating of transducer face coating and this parallel operation consistent color of living in.
The present invention has mainly solved halfway required increase interim branch and need not increase the situation of the high equipment that is press-fitted of high-tension cable long distance powedr transmission, design a kind of conversion equipment and substitute high-tension distribution equipment, the technology of the present invention is used in engineering and had both been saved construction investment, also reduces engineering maintenance, maintenance cost;
The present invention has also solved in the high pressure long distance powedr transmission way two power cables because the situation that the need that are difficult to wiring are set up the temporary high-pressure controller switching equipment is not mated in the core wiring, designing a kind of conversion equipment connects the cable of different model, and reach safety requirements, present technique is saved 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 present invention has also solved high pressure power supplying and distributing equipment cabinet internal wiring terminal to the cable mismatch of the high voltage power transmission that configures, and namely the high voltage supply cable is because the problem that limited space is difficult to wiring in the feeding pannel cabinet.Conversion equipment of the present invention becomes the cable of numerous cores power supply into less core service cable, makes the cable after the conversion can be in the smoothly wiring of equipment of the confined space.
Description of drawings
Below, the present invention is further illustrated by reference to the accompanying drawings:
Fig. 1 is described transducer schematic diagram.
Embodiment
As shown in Figure 1: a kind of high voltage cable core conversion method, it is arranged between the cable to be converted, and it comprises the following steps:
Step 1, transducer is made, and this transducer comprises a main pitman 1, and these main pitman 1 two ends are with at least one branch's linkage section 2, and branch's linkage section 2 ends and main pitman 1 two ends are provided with splicing ear 3;
Step 3 is to every unit cable head plastic packaging.
Described high voltage cable core conversion method, described step 1 also are included in the coating (failing among the figure to express) of transducer face coating and this parallel operation consistent color of living in.
Claims (3)
