Pre-hinge splitting spacer

Abstract

The invention relates to a pre-hinge splitting spacer. The pre-hinge splitting spacer comprises a V-shaped framework, two clamp arms and two clamp pressing plates, wherein middle portions of the clamparms are in rotation connection with two arms of the V-shaped framework through a rotation shaft, tail ends of the two clamp arms are provided with baffle blocks, the two arms of the V-shaped framework are provided with limit grooves for disposing the baffle blocks, an upper end of the clamp pressing plates is connected with a tail end of the clamp arms through a pin, the other end of the clamp pressing plates is clamped through a locking rod mounted on the clamp arms, and damping pads are mounted in semi-circular arcs of the clamp arms and the clamp pressing plates. The pre-hinge splitting spacer is advantaged in that the structure is simple, the tail ends of the clamp arms are provided with the baffle blocks, so the baffle blocks can swing in the limit grooves, effective lead vibrationdamping is realized, lead wear is reduced, and service life of the leads and the spacer is prolonged.

Description

technical field [0001] The invention relates to a pre-hinged two-split spacer bar. Background technique [0002] In transmission lines, in order to adapt to high-voltage and large-capacity transmission, large-section conductors are often used, and two conductors in one phase are arranged horizontally. If an accident occurs, a large short-circuit current will be generated, which will often cause the two clamp bodies to approach each other and the conductors will touch each other. Therefore, a two-split spacer is installed in the line to maintain the distance between the two wires and suppress the majestic vibration to ensure the safe operation of the transmission line. However, the two wire clips of the existing two-split spacer are fixed relative to the spacer frame, and the long-term swing will not only wear the wires, but also reduce the service life of the two-split spacer due to the generated stress. SUMMARY OF THE INVENTION [0003] In view of the above defects, the ...

Problems solved by technology

However, the two clamps of the existing two-split spacer are fixed relative to the frame of the spacer. Long-term swinging will not only wear the wires, but also reduce the service life of the two-split spacer due to the stress generated.
