Abstract
A D-side sleeve lead connecting fitting comprises two wire clamp bodies, wherein one sides of the two wire clamp bodies are formed into transformer sleeve lead-out holes, and the other sides of the two wire clamp bodies are provided side by side with two groups of glands; four lead lead-out holes in the same direction are formed between the glands and the wire clamp bodies; each group of glands are composed of two outer glands and an inner gland; the wire clamp bodies are provided with screw holes, and the outer glands are fixed to the wire clamp bodies through bolts in the screw holes; the transformer sleeve lead-out holes are perpendicular to the lead lead-out holes; positions on the wire clamp bodies, which are corresponding to the transformer sleeve lead-out holes, are provided with copper aluminum composite sheets; and for a part of each lead lead-out hole being corresponding to the wire clamp bodies and the outer glands, the diameter of the outer side segment of the part is larger than that of the inner side segment of the part, and an alleviation transition groove is arranged between the inner side segment and the outer side segment. The D-side sleeve lead connecting fitting is suitable for indoor direct-current substations, has large current-carrying capacity, does not generate corona, can reduce conductor resistance, and can guarantee that the leads are tightly pressed and that the leads are not damaged at wire clamp outlets during long-term operation of the project.
Description
Technical field
The utility model relates to a kind of D side sleeve pipe and connects the lead gold utensil.
Background technology
Existing pipe bus gold utensil mainly is applicable to outdoor AC Substation, be the split-type structural that is constituted by two wire clamps and gland, the wire clamp of gold utensil one side, gland are fixed together by bolt, nut and pipe bus, and gold utensil opposite side wire clamp, gland are by bolt, nut and two lead fixed together; By bolt, nut two wire clamps are linked together, connect because adopting bolt between two wire clamps, increased wire clamp resistance, increased current loss, reduced the lead current capacity, the transformer outlet that is not suitable for the direct current indoor substation connects.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly is applicable to that indoor direct current transformer station and ampacity are greatly, can not produce corona, can reduce conductor resistance, both can guarantee to compress lead, can guarantee again engineering long-time running wire clamp exit also not the D side sleeve pipe of damage wires connect the lead gold utensil.
The D side sleeve pipe that the utility model relates to connects the lead gold utensil, by two wire clip bodies that connect by screw bolt and nut, one side of two wire clip bodies forms the bushing shell for transformer fairlead, its special character is: the opposite side at two wire clip bodies is provided with two groups of glands side by side, form four lead fairleads in the same way between described gland and the wire clip body, every group of gland is respectively by two outer glands, an internal gland outside two between the gland constitutes, in, external pressure covers and is provided with installing hole, on the described wire clip body in the correspondence, the installing hole place of outer gland be provided with screw and in, outer gland is by being installed in being bolted on the wire clip body in the described screw, described bushing shell for transformer fairlead is vertical with lead fairlead direction, the corresponding transformation pipe-in-pipe of described wire clip body fairlead place is provided with copper aluminium composite sheet, the segmentum laterale diameter of the corresponding wire clip body of described lead fairlead and external pressure cap position is greater than the medial segment diameter, and is provided with between medial segment and the segmentum laterale and alleviates lead-over groove.
The corresponding wire clamp of described lead fairlead and the segmentum laterale diameter of external pressure cap position and the difference of medial segment diameter are 1-2mm.
Be provided with reinforcement in the middle of the described wire clip body inboard, increase body intensity, and increase the gold utensil current-carrying, improve the gold utensil heat radiation.
The utility model has the advantages that:
1, this gold utensil main body is integral type, and middle no transition connects, and has reduced conductor resistance, has reduced electric energy loss.
2, wire clip body is connected side and has copper aluminium composite sheet with sleeve pipe, can be connected with copper sleeve, when being connected with sleeve pipe, two wire clamps are fixed together by bolt, nut and sleeve pipe, two equal current-carrying of body, each body can connect two leads, and ampacity doubles than former gold utensil.
3, wire clip body is connected the direct processing screw hole of side with lead, during stationary gland, bolt directly and wire clip body tighten, no longer need nut, bolt can be shielded by gold utensil fully like this, can not produce corona, and every cover gold utensil can be saved 24 nuts, 24 spring washers, 24 plain washers.
4, the segmentum laterale diameter of the corresponding wire clip body of described lead fairlead and external pressure cap position is greater than the medial segment diameter, and is provided with between medial segment and the segmentum laterale and alleviates lead-over groove.So namely can guarantee to compress lead, can guarantee also damage wires not of engineering long-time running wire clamp exit again.
