Description
Technical field
The utility model relates to the jointer in technical field of power systems, is specifically related to a kind of substation transformer extended type and applies copper jointing clamp.
Background technology
Current domestic electric armour clamp development rapidly, various power transformers with wire clamp because it is easy to use, popularize, quite perfect aspect once mounting.And changing when wire clamp, because wire clamp adopts crimping mode, so can only cut out original wire clamp (and wire) in wire clamp while changing wire clamp, at this moment the length of wire just cannot meet the demands.Therefore often changing a wire clamp all needs to change the wire (steel reinforced aluminium conductor) on wire clamp, wastes time and energy.Common single line is just changed needs more than one hour, and at this moment on wire clamp, expends the plenty of time and just cannot ensure repair quality changing, and will certainly threaten to the safe and stable operation of whole electrical network.And on market, all do not occur that the wire clamp addressing the above problem occurs at home and abroad at present.
Summary of the invention
For above-mentioned technical problem, the purpose of this utility model be to provide a kind of can be in the time changing again the extended type of restringing apply copper jointing clamp, this wire clamp has been saved a large amount of human and material resources, time, has also greatly strengthened operating personnel's fail safe.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of extended type applies copper jointing clamp, it is characterized in that: this wire clamp is mainly by wire clamp pressure contact portion, wire clamp lengthening part, wire clamp angular bend portion and the moulding of connecting plate formed by integrally casting; Described wire clamp pressure contact portion is positioned at topmost, and offers one for inserting the wire jack of wire; Described wire clamp pressure contact portion below is wire clamp lengthening part, wire clamp angular bend portion and connecting plate successively, described wire clamp angular bend portion can be between 0 °-90 ° free bend, on described connecting plate, offer connecting bolt hole.
Preferred version in technique scheme, described wire clamp angular bend portion can be between 0 °-60 ° free bend.
Preferred version in technique scheme, the length of described wire clamp lengthening part is 120mm-150mm.
The beneficial effects of the utility model are:
1, in the utility model owing to having increased a wire clamp lengthening part, can adapt to the length of original wire, restringing more just in the time changing; Therefore this wire clamp has been saved a large amount of human and material resources, time, has also greatly strengthened operating personnel's fail safe;
2, the wire clamp angular bend portion in the utility model can free bend, and the clamp that makes this wire clamp can adapt to difference (owning) angle is installed;
3, easy to operate, safe and reliable, reduce activity duration and the events in operation of changing wire clamp; Practicality is high, often need to change in routine duties wire clamp, and utilance is high; Economic benefit is high, has saved the expense of changing wire, and single wire clamp is changed and at least saved 150 yuan.

In figure: 1-wire clamp pressure contact portion, 2-wire clamp lengthening part, 3-wire clamp angular bend portion, 4-connecting plate, 5-wire jack.
Embodiment
In order to understand better the utility model, below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further to (as Figure 1-3).
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of extended type applies copper jointing clamp, and this wire clamp is mainly by wire clamp pressure contact portion 1, wire clamp lengthening part 2, wire clamp angular bend portion 3 and connecting plate 4 formed by integrally casting moulding; Described wire clamp pressure contact portion 1 is positioned at topmost, and offer one opening up for inserting the wire jack 5(wire jack 5 of wire, according to the wire diameter size of wire, the degree of depth of wire jack 5 and diameter are not identical, can work in-process press model specification adjustment); Described wire clamp pressure contact portion 1 below is wire clamp lengthening part 2, wire clamp angular bend portion 3 and connecting plate 4 successively, described wire clamp angular bend portion 3 can at free bend between 0 °-90 °, (described wire clamp angular bend portion 3 be between 0 °-90 ° when free bend, and the angle between connecting plate 4 and wire clamp pressure contact portion 1 and wire clamp lengthening part 2 also changes accordingly; According to joint connection in site angle needs, wire clamp angular bend portion 3 can bend to 0 °, 30 ° [as shown in Figure 3], 60 °, 90 °), on described connecting plate 4, offer connecting bolt hole.
Preferred version in technique scheme, described wire clamp angular bend portion 3 can be between 0 °-60 ° free bend.According to the bending situation of field wires, wire clamp itself also needs bending, and wire clamp angular bend portion 3 generally can be bent to 60 °, as more wide-angle (60 °-90 °) of need, is beforehand with mould and directly builds need to dispatch from the factory time, in case wire clamp fracture when artificial bending.
Preferred version in technique scheme, the length of described wire clamp lengthening part 2 is 120mm-150mm.According to field wires thickness, wire jack 5 is made 240mm, 300mm, 400mm wire diameter; Differ according to the wire diameter of wire, the length of wire clamp lengthening part 2 is not identical yet, and as the wire diameter of 240mm, wire clamp lengthening part 2 is 120mm; The wire diameter of 300mm, wire clamp lengthening part 2 is 130mm; And the wire diameter wire clamp lengthening part 2 of 400mm is 150mm.
Specific implementation method of the present utility model:
1) by extremely light of old wire polishing, by bright partial insertion wire jack 5 until its bottom; Use proper mold with Crimping Pliers, jointing clamp pressure contact portion 1, by tight, firm to wire clamp pressure contact portion 1 and conductor compression jointing;
2) according to demand, wire clamp angular bend portion 3 is bent to suitable angle (30 °, 60 °, 90 ° etc.);
3), according to quantity and the position of equipment (being transformer) junction block bolt hole, on connecting plate 4, offer the connecting bolt hole that quantity and position match and (be generally four of two row two row, as shown in Figure 1), then it be fixedly connected with equipment junction block with bolt.
Above-described is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalence of therefore doing according to the utility model claim changes, and still belongs to protection range of the present utility model.
