Abstract
The utility model discloses a U-shaped insulating net covered transposed conductor, comprising a net covered transposed conductor, and a U-shaped insulation paper slot outside the net covered transposed conductor. The insulation paper slot and the net covered transposed conductor are tightly wrapped by net covered strips. Through additionally wrapping U-shaped insulators on part of the net covered transposed conductor, insulating strength on positions right against high and low voltage is enhanced, and heat dissipation effect of the net covered transposed conductor is not reduced.
Description
Technical field
The utility model relates to a kind of transposed conductor, is the net pack transposition conducting wire of a kind of outsourcing " U-shaped " insulating barrier specifically.
Background technology
The coil windings project organization of EHV transformer is compact at present, and loss reduces, and low-pressure section, for increasing radiating effect, has adopted net pack transposition conducting wire, brings thus insulation distance between coil high-voltage coil and low-voltage coil to dwindle the risk that punctures causing.
Summary of the invention
The utility model provides a kind of " U-shaped " insulation net pack transposition conducting wire, both can strengthen high-low pressure over against the dielectric strength of locating, and did not reduce again the guarantee replacement radiating effect of bit line of net.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of " U-shaped " insulation net pack transposition conducting wire, comprise net pack transposition conducting wire, it is characterized in that net pack transposition conducting wire is outside equipped with " U-shaped " insulating paper groove, is packed tightly by net band between " U-shaped " insulating paper groove and net pack transposition conducting wire.
Good effect of the present utility model: add bag " U-shaped " insulation in net pack transposition conducting wire part, both can strengthen high-low pressure over against the dielectric strength of locating, do not reduce again the guarantee replacement radiating effect of bit line of net.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, " U-shaped " of the present utility model insulation net pack transposition conducting wire, comprises net pack transposition conducting wire 1, at net pack transposition conducting wire 1, is outside equipped with " U-shaped " insulating paper groove 2, between " U-shaped " insulating paper groove 2 and net pack transposition conducting wire 1, by net band, is packed tightly.
The manufacture craft of " U-shaped " insulation net pack transposition conducting wire is as follows:
Cathode copper is after electromagnetic oven melts, and the mode of use non-oxygen continuous casting is made and drawn copper bar; On non-oxygen continuous casting, draw bar and roll into hard state rolled bar base through finishing mill; Rolled bar is drawn into copper strap wire after draw down, multiple tracks mould; Copper strap wire is annealed, clean, repeatedly strengthening, repeatedly japanning (insulating varnish and self-adhesion paint) and baking repeatedly, reaches certain insulation thickness, yield strength, finally go into can continuous shifting enamelled wire; Many enamelled wires are made two row, and through transposition equipment continuous shifting, outsourcing strengthening grid takes certain thickness to, forms net pack transposition conducting wire, in this process middle distance 1/4 extension position of starting, place " U-shaped " insulating paper groove, with net band, pack tightly.
