Embodiment
Below in conjunction with the drawings and specific embodiments, steel pipe type cable rotated conductors of the present utility model and cast inner core are described in further detail.
As Fig. 1, shown in Fig. 3, steel pipe type cable rotated conductors of the present utility model, comprise hollow spherical part 1, the both sides of hollow ball part 1 connect the conductor part 2 of one section of tubular structure respectively, the conductor part 2 of hollow ball part 1 and two sections of tubular structures is shaping by casting die one one-step casting, between the conductor part 2 of two sections of tubular structures, there is the angle set according to actual needs, between the conductor part 2 of two sections of tubular structures, the adjusting range of angle is 79 ° ~ 179 °, this steel pipe type cable rotated conductors is mainly used in the through-flow conductor of steel pipe type cable conductor bend loss structure, bear the alternating current conveying function of steel pipe type cable.
Wherein, the conductor part of said hollow ball part and two sections of tubular structures is cast by the aluminum alloy materials of high conductivity and is formed.Be welded to connect between the conductor part 2 of tubular structure with the outer linear conductor needing to be connected or connected by active joint (multipoint mode movable contact structure), its connected mode can also be hot extrusion version, Mume flower contact structure etc.
A kind of cast inner core for above-mentioned steel pipe type cable rotated conductors, comprise spherical inner core 4 and two sections of cylindrical inner core 5, wherein one section of cylindrical inner core and the spherical inner core 4 of said two sections of cylindrical inner core 5 connect as one and form stationary core 6, between other one section of cylindrical inner core and spherical inner core 4, adjustable angle forms adjustable inner core 7, by regulating the position of adjustable inner core 7 along the circumferencial direction of spherical inner core 4, the angle between stationary core 6 and adjustable inner core 7 is made to meet angle requirement between rotated conductors tubular structure, angular range can be arbitrarily angled between 79 ° ~ 179 °.
When rotated conductors for steel pipe type cable manufactures, the size of the included angle A between the conductor part first determining two sections of tubular structures on rotated conductors according to steel pipe type cable engineering practice, then the position of the adjustable inner core 7 on casting die inner core is adjusted, make the included angle B between adjustable inner core 7 and stationary core 6 and included angle A in the same size, and then the assembling of other parts of casting die is completed, after the cast molding of rotated conductors blank, finally need its final machine-shaping according to part drawing.
