Description
Technical field
Master clamp of the present invention, belongs to the technical field of master clamp.
Background technology
At present, the supporting way of busbar is generally insulator and supports and common bus clip support two large classes, when insulator supports busbar, need to punch on busbar, with bolt, busbar is fixed on the insulator, although this supporting way is firm, but because inevitably punching on busbar, so reduce the ampacity of busbar, in addition, when busbar expands with heat and contract with cold, the length variations of generation cannot be compensated, stress will all be applied on insulator, even causes Insulator detection in severe case;
When common master clamp supports busbar, usually, between master clamp and busbar, can gap be there is on busbar Width or thickness direction, make master clamp on the Width of busbar and thickness direction, busbar cannot be clamped simultaneously; When busbar is by alternating current, because the electric power be applied on busbar is the alternating force with electric current same frequency, so there will be the situation that busbar does not stop to beat master clamp, and, because the conventional making material of common master clamp is hard insulation, so larger vibrations noise can be produced, not only interference is caused to surrounding people, also can affect the safe operation of equipment; In addition, the non-constant of versatility of common master clamp, for the busbar of feature specification, specific configuration mode, specific master clamp must be equipped with, if change specification or the arrangement mode of busbar, then must change master clamp, bring inconvenience to the work of buying and management busbar.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved is: provide one on busbar Width and thickness direction, can clamp busbar simultaneously, and the master clamp that versatility is extremely strong.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: master clamp, comprises at least one unit master clamp; Described unit master clamp comprises the primary and secondary row folding that two structures are identical, horizontal symmetrical is arranged, described primary and secondary row folding comprises the collets that at least two in the vertical directions are stacked together, upper part and the end portion of each collets side are provided with step locating surface, step locating surface between two adjacent collets surrounds the groove that is blocked busbar in the horizontal direction jointly, and the distance up and down between two horizontal planes of described groove and the thickness of busbar adapt; In primary and secondary row folding described in two, each collets have through hole all vertically, and the upper and lower of each primary and secondary row folding is provided with a gold utensil, described gold utensil is the connector of sheet, comprises the horizontal component and vertical portion that are connected as a single entity, the horizontal component of each gold utensil all has hole; All collets in a sub-master clamp and two gold utensils being located thereon below are worn together by the first stud, and fasten by two nut clip, all collets in another primary and secondary row folding and two gold utensils being located thereon below are worn together by the second stud, and fasten by two nut clip; The vertical portion of described gold utensil also has hole, is linked together by the 3rd stud and two nuts between the vertical portion of two gold utensils of primary and secondary row folding the same side; Be parallel to each other between multiple described unit master clamp or be arranged vertically, and connecting by adjacent gold utensil is connected as a single entity between adjacent two unit master clamps.
The vertical plane contacted with the vertical side of busbar in described groove is the cambered surface of evagination, and when busbar expands with heat and contract with cold, the size of busbar and change in displacement are adapted to the vertical plane in radian in above-mentioned groove; Described first stud replaces with two nuts first bolt be mated and a nut; Described second stud replaces with two nuts second bolt be mated and a nut; Described 3rd stud replaces with two nuts the 3rd bolt be mated and a nut; Collets in described primary and secondary row folding are made by having flexible insulating material.
The present invention compared with prior art has following beneficial effect:
When 1, using, busbar is put into the relevant position of unit master clamp, tighten the nut at the first stud, the second stud two ends respectively, by applying certain power to the gold utensil of unit master clamp upper and lower, by the collets of centre be positioned at collets groove and the busbar that its thickness and recess width adapt clamps, achieve busbar clamping in the thickness direction thereof; Tighten the nut at the 3rd stud two ends, certain power is applied to the gold utensil of unit master clamp the same side, corresponding gold utensil drives the first stud and the second stud to apply pressure to collets respectively, the busbar clamping that corresponding collets will be clipped in the middle, achieves busbar clamping in its width direction;
Master clamp in the present invention can clamp busbar on busbar width and thickness direction simultaneously, decreases the vibrations degree of busbar, reduces and shakes the noise pollution that causes to the impact of surrounding environment by busbar; In addition, can make to be parallel to each other between multiple unit master clamp or to be arranged vertically, be spliced into various multi-form with the various installation requirements adapting to busbar, largely, improve the versatility of master clamp;
2, the collets in the master clamp in the present invention are made by having certain flexible insulating material, after master clamp clamping busbar, there will not be gap between collets and busbar, the vibrations of busbar can be absorbed by resilient collets, and the vibrating noise more reducing busbar pollutes;
3, the vertical plane contacted with the vertical side of busbar in groove in master clamp in the present invention is the cambered surface of evagination, namely the vertical plane in groove is made up of the plane of centre and the inclined-plane of both sides, under normal circumstances, by the planar support busbar of centre, when busbar expands with heat and contract with cold, because busbar clamps by collets, so the length variations of busbar can drive collets to turn over necessarily small angle, at this moment in collets, one of them inclined-plane of perpendicular is more close with busbar, substitute original mid-plane and become new busbar supporting surface, the stress that busbar expands with heat and contract with cold is compensated.
