Abstract
The utility model relates to a parallel groove clamp for power lines. An upper and a lower clamping plates are buckled together, and the buckling surface is provided with two parallelly opposite concave wiring troughs which are tightly fixed by the penetration of screw bolts, screw nuts and washers from the middle. A middle concave trough which is arranged in full length is arranged at the middle part, which is parallel to the two concave wiring troughs of the buckling surface of the lower clamping plate. Both sides of a screw bolt trough on the top of a non buckling surface of the upper clamping plate are provided with two steps which are lower than the top surface, and the edges at both sides of the upper and the lower clamping plates present in circle arc shapes. Longitudinal or horizontal non-skid convex stripes are arranged on the inner surfaces of the concave wiring troughs. Under the condition of conforming to the national standard of transmission performance and safety performance of power, the parallel groove clamp is made of good quality aluminium alloy, and has improved shapes and the advantages of reasonable design, simple manufacture, good ventilation and heat dissipation, favorable protection effect on transmission lines, material saving, light weight and lower manufacturing cost. The parallel groove clamp is suitable for the connection engineering of steel strand wires, aluminum strand wires or steel-cored aluminium strand wires of overhead power lines.
Description
Technical field
The utility model relates to a kind of electric armour clamp, particularly a kind of power circuit parallel groove clamp.
Technical background
Existing power circuit parallel groove clamp is usually cast with cast alumin(i)um, owing to consider requirement of strength, its shaped design is comparatively thick and heavy.It is snapped together by train wheel bridge, lower plate, and its buckling surface has parallel relative twice spill wire casing, and there is bolt slot the top of the non-buckling surface of train wheel bridge, penetrates fastening from the middle part by bolt, nut, packing ring.There is the problem of poor heat radiation at its solid wire clamp center, after adopting the fine aluminum alloy to make, also is necessary to improve its shape, under the condition that is implemented in influence technique performance not, saves material, reduces cost, and alleviates the weight of wire clamp.
Technology contents
The utility model solves the technical problem of power circuit parallel groove clamp center poor heat radiation, and under the condition that does not influence every technical performance, saves material, reduces cost, and alleviates the weight of wire clamp.
The technical scheme of power circuit parallel groove clamp: train wheel bridge, lower plate snap together, its buckling surface has parallel relative twice spill wire casing, there is bolt slot the top of the non-buckling surface of train wheel bridge, penetrate fastening from the middle part by bolt, nut, packing ring, it is characterized in that: there is further groove at the middle part that is parallel to twice spill wire casing at the buckling surface of lower plate, the elongated setting of further groove.
There are two steps that are lower than end face the bolt slot both sides, top of the non-buckling surface of above-mentioned train wheel bridge.
The both sides of the edge of above-mentioned train wheel bridge and lower plate are circular arc.
On the above-mentioned spill wire casing inner face vertical or horizontal anti-skidding burr is arranged.
Beneficial effect: the utility model is meeting on the basis of national standard; adopt the manufacturing of fine aluminum alloy, improved the shape at wire clamp middle part and edge, it is reasonable in design; processing technology is simple; under the condition that does not influence wire clamp power delivery performance and safety and reliability, the ventilation and heat at the upper and lower clamping plate of wire clamp center is good, helps the protection of transmission line; simultaneously; save material, weight reduction, the manufacturing cost of reduction wire clamp.This power circuit parallel groove clamp is applicable to steel strand wire, aluminium stranded conductor or the steel reinforced aluminium conductor of the overhead power line engineering that continues.
