Description
Technical field
The utility model relates to Double passing through type sleeve joint for high voltage cable.
Background technology
The application of Double passing through type sleeve joint for high voltage cable in electric power system is more and more extensive.Traditional bilateral sleeve pipe electric conductor tightens assembly connection mutually by four steel structure part screw threads, fits together after this frame mode needs process part one by one again.Be disclose a kind of Double passing through type sleeve joint for high voltage cable in the patent documentation of 2001.7.18 as be the ZL00225187.6 applying date in the patent No. being 2000.7.8 authorized announcement date, each part in electric conductor in the joint of this structure is exactly interconnective by screw thread, this form touch point is many, easily cause contact resistance unstable, resistance range is large.As built-in rubber copper piece, when injecting sizing material, because injection pressure is large, the contact-making surface between copper piece can produce certain gap, and sizing material easily infiltrates in contact gap, causes loose contact, causes contact resistance to increase.Below all can cause the temperature rise of bilateral sleeve pipe overcurrent copper piece faying surface, conductive capability declines, and power supply reliability is poor, forms potential safety hazard.
Summary of the invention
The utility model provides anti-breaking, the locking sleeve pipe electric conductor of a kind of integral type, and the utility model structure is simple, and easy to process, can not form seam between electric conductor, make the resistance range of electric conductor little, temperature rise is low, and conductive capability is good, and power supply reliability is good.
For achieving the above object, the sleeve pipe electric conductor that integral type is anti-breaking, locking, comprises intermetallic metal part and both sides metalwork; Intermetallic metal part has through hole, is provided with torque limiting metal assembly in through hole; Between both sides metalwork and intermetallic metal part, be provided with arc transition metalwork, intermetallic metal part, arc transition metalwork and both sides metalwork are one-body molded.
Intermetallic metal part is integrally formed with both sides metalwork by arc transition metalwork, the connection between can effectively reducing because of parts and form contact gap, and the situation preventing sizing material to infiltrate contact gap occurs; Make this conductor construction simple, easy to process, can not form seam between electric conductor, the contact resistance of electric conductor is stablized, and resistance range is little, and temperature rise is low, and conductive capability is good, and power supply reliability is good.
Further, the seamed edge on electric conductor has circular arc chamfering.Outer edge position completes by arc transition entirely, reduces the partial discharge phenomenon that may occur due to tip.
Further, external screw thread and internal thread is provided with at both sides metalwork away from the end of arc transition metalwork.Described external screw thread is for connecting aluminum pipe, and described internal thread is for connecting conducting rod.
Further, described torque limiting metal assembly comprises screw rod, backing plate, ratchet and seal cover; Through hole is stepped hole; Screw rod is the Step Shaft that one end diameter is greater than other end diameter, the small end of screw rod through the large end of stepped hole through the small end of stepped hole, the large end of screw rod is positioned at the large end of stepped hole, contact with screw rod in the large end that backing plate is located at stepped hole, seal cover covers in the large end of stepped hole, and ratchet is between backing plate and seal cover.When screw rod screws, ratchet can sound prompting fastening, this torque limiting metal assembly structure can guarantee that stud can not be twisted into two parts, and screw rod can turn arbitrarily angled by demand, under the effect of seal cover and ratchet, screw rod its end face of optional position in 360 ° all can not loosened by effectively compressing.
Further, intermetallic metal part, arc transition metalwork and both sides metalwork are Y-shaped.
Accompanying drawing explanation
Fig. 1 is outside schematic diagram after anti-breaking, the locking sleeve pipe electric conductor die cast of integral type.
Fig. 2 is that after anti-breaking, the locking sleeve pipe electric conductor of integral type, operation machines schematic diagram.
Fig. 3 is that anti-breaking, the locking sleeve pipe electric conductor of integral type can turn clockwise end view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1, one-body molded by intermetallic metal part 1, arc transition metalwork 2 and both sides metalwork 3 by the sleeve pipe electric conductor that the one that die casting is shaping is anti-breaking, locking.Wherein, intermetallic metal part 1 is intermediate cylindrical copper piece, and arc transition metalwork 2 is arc transition copper piece, and both sides metalwork 3 is both sides cylinder copper piece, and in the present embodiment, both sides cylinder copper piece is two, and electric conductor is Y-shaped.
As shown in Figure 2, anti-breaking, the locking sleeve pipe electric conductor of one comprises intermediate cylindrical copper piece, arc transition copper piece, both sides cylinder copper piece and torque limiting metal assembly, and the seamed edge of electric conductor is circular arc chamfering, reduces the partial discharge phenomenon that may occur due to tip.Intermediate cylindrical copper piece, arc transition copper piece and both sides cylinder copper piece are structure as a whole.Connection between can effectively reducing because of parts and form contact gap, the situation preventing sizing material to infiltrate contact gap occurs; Make this conductor construction simple, easy to process, can not form seam between electric conductor, the contact resistance of electric conductor is stablized, and resistance range is little, and temperature rise is low, and conductive capability is good, and power supply reliability is good.
Intermetallic metal part has through hole, and through hole is stepped hole, and wherein the large end of through hole is near arc transition copper piece.
External screw thread 8 and internal thread 9 is provided with away from the end of arc transition copper piece in both sides copper piece.Described external screw thread 8 is for connecting aluminum pipe, and described internal thread 9 is for connecting conducting rod.
Described torque limiting metal assembly comprises screw rod 4, backing plate 5, ratchet 6 and seal cover 7; Described seal cover is aluminum.Screw rod 4 is greater than the Step Shaft of other end diameter for one end diameter, and the small end of screw rod 4 has internal thread hole 10.The small end of screw rod 4 through the large end of stepped hole through the small end of stepped hole, the large end of screw rod 4 is positioned at the large end of stepped hole, contact with screw rod in the large end that backing plate 5 is located at stepped hole, seal cover 7 covers in the large end of stepped hole, and ratchet 6 is between backing plate 5 and seal cover 7.This structure, when screw rod 4 screws, because of the effect of ratchet 6, sounding between screw rod 4 and backing plate 5, it is fastening to point out, this torque limiting metal assembly structure can guarantee that stud can not be twisted into two parts, screw rod 4 can turn arbitrarily angled by demand, and under the effect of seal cover 7 and ratchet 6, screw rod 4 its end face of optional position in 360 ° all can not loosened by effectively compressing.
