Abstract
The utility model relates to a clamp for an irregular vertical bus. The utility model is characterized in that a limiting fixing seat is provided with three limiting mould cavities which match with the fixed end of the irregular vertical bus, the middle of the limiting mould cavity is provided with a fixing hole which can be sheathed with an insulating fixing sleeve and a T type fixing bolt which is directly fastened on an installing beam through the insulating fixing sleeve, and the fastening end of the T type fixing bolt is provided with an operculiform nut which is made of insulating material; besides, the electric insulating distance and the gas distance between the limiting fixing seat and the insulating fixing sleeve and between the operculiform nut, the irregular vertical bus and the T type fixing bolt are both larger than 20 mm. The utility model has the advantages that the requirement of the intensity of manufacture material of the clamp for the bus is lowered, and the dynamic thermal stability of the clamp for the vertical bus is increased; the material consumption of the clamp for the bus is saved, and the manufacture cost is reduced; the requirements of electric insulation and the electric gap between the vertical bus and a T type bolt electrified body as well as a cabinet metal installing beam are ensured; the clamp structure is simplified, and the external shape of the clamp is smart, brief and beautiful.
Description
Technical field
The utility model relates to the special-shaped vertical bus anchor clamps that a kind of low pressure draw out switchgear cabinet motor control cabinet is used.Belong to the technical field that the low-voltage distribution cabinet special purpose parts is made.
Background technology
Existing low-voltage distribution cabinet Bus line cramp, relatively typical case and commonly used all serving as reasons and upper and lower two mutual clampings of insulator that shape of generatrix matches and forming, because the structural limitations of Bus line cramp, bus is on the mounting rail that can not directly be fixed in the cabinet, the clamping that can only lean on upper and lower two insulators is with the bus positioning and fixing, and can not directly be clamped in bus on the mounting rail, therefore the clamp material to the clamping bus has certain intensity requirements, otherwise just is difficult to guarantee anchor clamps needed requirement of strength by dynamic and thermal stability the time.Because in die cavity, so the consumption of clamp material will increase accordingly, it is clumsy that the construction profile of anchor clamps also seems with the whole double teams of the profile of bus for prior art requirement anchor clamps.
Summary of the invention
The utility model purpose is to overcome the defective of above-mentioned existence, propose a kind of have bear anti-dynamic and thermal stability performance good, easy to install and use, reasonable, with the special-shaped vertical bus anchor clamps of characteristics such as material province, good looking appearance.Technical solution of the present utility model: on spacing holder, be provided with three spacing die cavities that match with special-shaped vertical bus stiff end, a fixing hole that can be inserted in insulation fixed cover and T type set bolt is arranged in the middle of the spacing die cavity, T type set bolt directly is fastened on the mounting rail by the insulation fixed cover, is provided with one and is made by insulating material on the fastening end of T type set bolt
Cap nut.Electric insulation distance between spacing holder and insulation fixed cover and cap nut and special-shaped vertical bus and the bolt and clearance distance are all greater than 20mm.
Advantage of the present utility model: reduced requirement, improved the dynamic and thermal stability ability of vertical bus folder to Bus line cramp manufactured materials intensity; Because bus passes the spacing holder of monolithic and is connected with mounting rail, bus clip need not bus profile double team interior, thereby saved the material consumption of half Bus line cramp approximately, reduced the manufacturing cost of Bus line cramp, between spacing holder and mounting rail, install the insulation positioning sleeve additional, thereby guaranteed electric insulation and electric clearance requirement between vertical bus and T type bolt electrified body and the rack metal mounting rail; Because clamp structure is simplified, and is comparatively convenient to the design of moulding, the also corresponding dexterity of the profile of anchor clamps, succinctly attractive in appearance.
Description of drawings
Accompanying drawing 1 is that the utility model is installed in the structural representation on the mounting rail.
Accompanying drawing 2 is partial cutaway diagrammatic sketch of Fig. 1.
Among the figure 1 is spacing holder, the 2nd, vertical bus, the 3rd, and insulation positioning sleeve, the 4th, T type bolt, the 5th is by the acorn nut, the 6th that insulating material is made, spacing die cavity, the 7th, mounting rail.
Embodiment
The special-shaped vertical bus of three-phase, place in the spacing holder 1 of monolithic that the insulating material of spacing usefulness makes, by T type bolt 4 special-shaped vertical bus 2, spacing holder 1 directly are fixed on the mounting rail 7, the ability of bus dynamic and thermal stability is just directly born by mounting rail in the power distribution cabinet 7 and T type bolt 4 like this.T type bolt 4 is put into the C type groove of special-shaped vertical bus, 90 ° of the bolt heads of rotation T type bolt 4, passing holder 1 is fastenedly connected with guaranteeing the electric insulation and the insulation positioning sleeve 3 of electric clearance and the bus mounting rail 7 in the power distribution cabinet, screw in the cap nut 5 that insulating material is made in the anchor clamps rear end, can avoid exposing of the charged part of bolt.
