The utility model has the advantages that:
The utility model can be realized the quick connection between two high-tension cables of identical electric pressure in the three-phase electrical power system, the problem that continues of the high-tension cable when having solved long distance power supply.The utility model structure is formed simple, and cost is low, and is reusable.
Description of drawings
Fig. 1 is the embodiment schematic diagram of the utility model high-voltage cable connector.
Embodiment
The utility model high-voltage cable connector comprises casing 31, offer cable access, cable outlet on this casing 31, be provided with two cable terminations in this casing 31, these two cable terminations connect via bus, and this bus is fixed on these casing 31 inwalls via insulator.Each cable termination can have a plurality of fingerstall 321, the fingerstall quantity that two cable terminations have is identical, each fingerstall 321 of a cable termination is connected with a corresponding fingerstall 321 of another cable termination via a bus 33 respectively, and each bus 33 is fixed on casing 31 inwalls via an insulator 34.
Fig. 1 shows an embodiment of the present utility model, as shown in Figure 1, each cable termination has three fingerstall 321, each fingerstall 321 of a cable termination is connected with a corresponding fingerstall 321 of another cable termination via a bus 33 respectively, and each bus 33 is fixed on casing 31 inwalls via an insulator 34.Insulator 34 has fixedly bus 33 and makes bus 33 and the effect of 31 insulation of casing.Certainly, according to actual needs, cable termination also can be designed to have the fingerstall quantity of 4 or 321, two cable terminations of 5 fingerstall also can be different.
In actual installation, as figure, preferably, fingerstall 321 is spirally connected with corresponding bus 33,33 of 33 parallel to each other and adjacent buses of bus are at a distance of a setpoint distance, this bus be arranged in parallel and this bus between setpoint distance be provided with can make that bus forms to the original more similar electric field of uniform electric field of turnover cable.
As Fig. 1, can be provided with automatic humidity controller 35 in the casing 31, be provided with ground stud 36 in the casing 31.In addition, in actual fabrication, casing 31 adopts δ=zinc-plated cold-rolled steel sheet of 2.5mm plastic-blasting (sheet metal) to make, and cable termination is a cold high pressure miniature cable termination, and bus 33 is a copper busbar, and insulator 34 is an epoxy resin pouring type insulator.
In practice, welding procedure has been adopted in making of the present utility model, and weld seam requires water-stop, and postwelding should be coated with waterproof gasket cement along the weld seam total length, and the rubber gasket sealing is all adopted at the perforate position in the utility model.
As Fig. 1, before the work, earlier the utility model to be installed in position, bus 33 parts such as grade all should be considered the safe distance problem over the ground.Then, cable access is passed in the end of inlet wire cable 10 to enter casing 31 back and is connected with the interface end of a cable termination, three fingerstall 321 of this cable termination are connected with corresponding core (three-phase core) in this inlet wire cable 10 respectively, the ground connection copper litz wire of this inlet wire cable 10 is connected with ground stud 36, this inlet wire cable 10 is fixed in this cable access via the stainless steel strain relief clamp, and realizes the tightening seal of this inlet wire cable 10 and this cable access by this stainless steel strain relief clamp.In like manner, the end of outlet cable 20 that will be identical with inlet wire cable 10 electric pressures is passed and is connected with the interface end of another cable termination after cable outlet enters casing 31, three fingerstall 321 of this cable termination are connected with corresponding core (three-phase core) in this outlet cable 20 respectively, reach between the corresponding core of two cable terminations and be connected, the ground connection copper litz wire of this outlet cable 20 is connected with ground stud 36, this outlet cable 20 is fixed in this cable outlet via the stainless steel strain relief clamp, and realizes the tightening seal of this outlet cable 20 and this cable outlet by this stainless steel strain relief clamp.After will connecting into and out of line cable 10,20, promptly finished " equipotential connection ", at this moment the door (not shown) on the casing 31 has been closed, the utility model just can be started working.
The layout of cable termination, bus 33 makes and has formed one and the akin uniform electric field of the turnover original AC field of line cable between inlet wire cable 10 and the outlet cable 20, thereby realized inlet wire cable 10 and outlet cable 20 are coupled together by " equipotential " principle, original uniform electric field can be not destroyed, the phenomenon that the insulating barrier of line cable punctures can not occur passing in and out and take place.When the air humidity in the casing 31 surpassed 75%, the just automatic energized of humidity controller 35 began heating and dehumidification automatically, and when humidity was lower than 75%, the power supply of humidity controller 35 excised automatically automatically.
The utility model has the advantages that: the utility model can be realized the quick connection between two high-tension cables of identical electric pressure in the three-phase electrical power system, the problem that continues of the high-tension cable when having solved long distance power supply.The utility model structure is formed simple, and cost is low, and is reusable.The utility model is applicable to mine, harbour, long apart from the problem that continues of the high-tension cable in large-scale open-air place such as tunnel and the construction site.Show safe and stable operation under can be in the tunnel strong dust of the utility model, the high humidity through practice.
Compare with the snap joint of import, the utlity model has the not available following advantage of snap joint:
1. observability, snap joint its internal structure in running can't be observed, and the utility model is when operation, if there is special requirement to observe;
2. reliability, the wiring pile crown of snap joint adopts thermofussion welding technology to connect, this thermofussion welding is because fusing point is lower, after the operating mode of equipment through overload or short circuit, the situation that solder joint snaps might appear, be that certain potential safety hazard is arranged, and the cable splice in the utility model be by bus and on bolted, comparatively reliable by comparison;
3. security and stability, the snap joint shell adopts casting aluminium material, because fragility is big, in construction and transportation, rupture, and the utility model is a body structure than being easier to, tank material uses sheet metal, cable is imported and exported and is adopted the stainless steel strain relief clamp, can not damage, and each parts can change, damage even individual component takes place, also can solve by timely replacing standby redundancy.
