Abstract
A square damping spacer for a wire of a power transmission line relates to the power equipment technology of power transmission line engineering and comprises an upper square frame, a lower square frame, a wire clamp body and a wire clamp cover plate, wherein the wire clamp body is clamped between the upper frame and the lower frame, a rubber pad is arranged between the wire clamp body and the frames, and a rubber pad is arranged in a wire slot of the wire clamp body and the wire clamp cover plate. The utility model discloses under the condition of equal size and sectional area, its atress intensity is criss-cross 1.414 times, can effectively strengthen the product and bear bigger short-circuit current's ability, it is safer to make the circuit, suitably increase the size, it is applicable in the large-section wire, be applicable to 500KV direct current transmission line engineering simultaneously, can effectively prevent that the wire that short-circuit current arouses from hitting, prevent the sub-conductor whip of span oscillation, prevent dizzy, locking, reduce breeze vibration intensity simultaneously, prevent natural phenomena such as deicing jump, galloping.
Description
Technical field
The utility model relates to the electric power equipment technology of power transmission line engineering.
Background technology
Generally adopt annular, cross and rectangle conductor spacer in the transmission line, and maximum is adapted to the ACSR-400/35 lead.Because of the circuit transmission capacity is little, line short circuit current is little, and conductor spacer bears that entad intensity of force is low.
The utility model content
The utility model purpose provides a kind of high strength that has, wind resistance pendulum, simple in structure, the big transmission line wire square frame form drag Buddhist nun conductor spacer in use line footpath of damping piece.
The utility model comprises two similar shape frameworks up and down, wire clip body on the holding frame and wire clamp cover plate, described framework is a square, wire clip body is clamped between upper and lower two frameworks, and between wire clip body and framework, rubber blanket is set, in the wire casing of wire clip body and wire clamp cover plate, rubber blanket is set.
The utility model is under the situation of comparable size and sectional area, it is subjected to force intensity is criss-cross 1.414 times, can effectively strengthen the ability that product bears bigger short circuit current, make circuit safer, suitable increased in size, applicable to large-section lead, be applicable to 500KV DC power transmission line engineering simultaneously, can effectively prevent the lead percussion that short circuit current causes, prevent the sub-wire flogging of subspan oscillation, reduce aeolian vibration intensity simultaneously, natural phenomena such as prevent to deice jump, wave, anti-corona and locking, and can install antiswing device additional.

Fig. 1 is the utility model structural representation;
Fig. 2 be among Fig. 1 A to partial schematic diagram.
Specific embodiment
Two frameworks 1 are square, four wire clip bodies 2 are arranged at four angles between two frameworks 1 respectively, each wire clip body 2 is clamped in 1 of upper and lower two framework, and between wire clip body 2 and two frameworks 1, rubber blanket 5 is set respectively, fixedly connected in addition by locating sleeve 6, joint fastening bolt 10, plain washer 12, spring washer 13, nut 12.Wire clamp cover plate 3 is connected with wire clip body 2 by chuck swivel pin 7, chuck locking pan axle 8, split pin 9.Simultaneously, also in the wire casing of wire clip body 2 and wire clamp cover plate 3, rubber blanket 4 is set.
Claims (1)
1, transmission line wire square frame form drag Buddhist nun conductor spacer, comprise two similar shape frameworks up and down, wire clip body on the holding frame and wire clamp cover plate, it is characterized in that described framework is square, wire clip body is clamped between upper and lower two frameworks, and between wire clip body and framework, rubber blanket is set, in the wire casing of wire clip body and wire clamp cover plate, rubber blanket is set.
