Description
Technical field
The invention belongs to cable R & D design technical field, especially relates to a kind of separately excited DC machine Special electric
Cable.
Background technology
At present, so-called dc motor has two classes: a class is the motor with commutating brush device, and another kind of is band
There is the permanent magnet brushless electromotor Middle Size DC of inverter due to its excellent speed adjusting performance, be widely used in steel rolling main
In drive apparatus, all using the separate excitation method of operation (main pole magnetic field is individually powered) when actual motion, armature voltage speed governing is
Speed regulation by constant torque, speed adjustable range is wide.Weak-magnetic speed-regulating is constant-power speed regulation, and speed ratio is up to 1:2 to 1:4.It is energized at armature circuit
Before, it is necessary to first it is energized to Main-pole windings.Within a cycle of armature travel process, Main-pole windings always is and leads to electric current,
And the electric current of armature circuit changes along with the increase and decrease of load.There is presently no corresponding separately excited DC machine cable, mostly make
Use with individual wires Split Down, affected by voltage pulsation and construction, owing to lacking outer jacket and screen layer, the most in use
Often produce puncturing of electromagnetic interference and electric wire, affect the stability of other equipment.
Summary of the invention
In view of this, the invention is directed to a kind of separately excited DC machine private cable, to overcome existing electric wire to exist
The most breakdown, the deficiency of generation electromagnetic interference in using.
For reaching above-mentioned purpose, the technical scheme of the invention is achieved in that
A kind of separately excited DC machine private cable, including the overall cable core in flat, outside described cable core from the inside to the outside
Lapping layer, screen layer and the restrictive coating set gradually；Described cable core includes two excitation wire and fit together side by side two
Root armature line, the outside of every described excitation wire and every described armature line is all coated with insulating barrier；Described excitation wire is the most right
That answers is arranged in armature line described in two and the crack space between described lapping layer.
Further, described lapping layer uses non-hygroscopic insulating tape lapping layer.
Further, described screen layer is copper strips or the wrapped metal screen layer of copper wire.
Further, described restrictive coating uses pe sheath or LSOH anti-flaming sheath.
Further, described insulating barrier is the high density polyethylene (HDPE) foaming bed of material.
Relative to prior art, the invention has the advantage that
Owing to the line footpath difference of excitation wire and armature line is relatively big, cable core is arranged to flat advantageously in saving into
This, separately excited DC machine private cable operation the most of the present invention is relatively simple, the available bigger raising of production efficiency.Meanwhile, should
Cable has a performance that can improve anti-external electromagnetic interference, and reduces cable itself to emission Electromagnetic Interference, significantly carries
The stability of high equipment, is conducive to improving power supply quality.

It can be the connection of two element internals.For the ordinary skill in the art, on can being understood by concrete condition
State term concrete meaning in the invention.
Describe the invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
A kind of separately excited DC machine private cable, as it is shown in figure 1, include the overall cable core in flat, outside described cable core
Lapping layer 1, screen layer 2 and the restrictive coating 3 that portion sets gradually from the inside to the outside；Described cable core includes two excitation wire 4 and side by side
Two armature lines 5 fit together, the outside of every described excitation wire 4 and every described armature line 5 is all coated with insulating barrier
6；In the crack space 7 that what described excitation wire about 4 was corresponding be arranged on described in two between armature line 5 and described lapping layer 1.
It should be noted that gap between excitation wire, between armature line and between lapping layer can be by fill the rope made of hemp, this
Sample, had both improved the structural strength of cable, and tension drags ability by force, meanwhile, the most effectively enhances the compressive property of cable, it is ensured that at him
During encouraging motor use, reliable and stable, it is hardly damaged.
Wherein, described lapping layer 1 uses non-hygroscopic insulating tape lapping layer, improves the heatproof of this cable, protection against the tide, resistance to compression
Performance, cable bend performance is good, and resistance to compression function of shielding is strong, and service life is long.
Wherein, described screen layer 2 is copper strips or the wrapped metal screen layer of copper wire, can improve anti-external electromagnetic interference
Performance, and reduce cable itself to emission Electromagnetic Interference.
Above-mentioned restrictive coating 3 uses pe sheath or LSOH anti-flaming sheath, selects according to different applying working conditions
Corresponding sheath, can be internally formed effectively protection, and have certain flame retardant effect cable.
Wherein, described insulating barrier 6 is the high density polyethylene (HDPE) foaming bed of material, between each excitation wire, between each armature line and armature
Good insulation is all defined between line and excitation wire.
Owing to the line footpath difference of excitation wire and armature line is relatively big, cable core is arranged to flat and easily facilitates wiring, simultaneously
Being also beneficial to cost-effective, separately excited DC machine private cable operation the most of the present invention is relatively simple, and production efficiency is available bigger
Raising.Meanwhile, this cable has the performance that can improve anti-external electromagnetic interference, and reduces cable itself to emission electromagnetism
Wave interference, is greatly improved the stability of equipment, is conducive to improving power supply quality.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all at this
Within the spirit of innovation and creation and principle, any modification, equivalent substitution and improvement etc. made, should be included in the invention
Protection domain within.
