Connection structure for suspension strain insulator string

Abstract

The present invention discloses a connection structure for a suspension strain insulator string. The connection structure comprises a pre-positive unit, a double-layer set square (15) and a second-change six-link plate (21). The double-layer set square (15) is provided with three string hanging holes (15.1). The second-change six-link plate (21) is provided with two string lifting holes (31) and six ring hanging holes (32). The pre-positive unit is connected with one string hanging hole (15.1) of the double-layer set square (15). The other two string hanging holes (15.1) of the double-layer set square (15) are respectively connected with the string lifting holes (31) of the second-change six-link plate (21) on the front and rear sides of the suspension strain insulator string. The ring hanging holes (32) of the second-change six-link plate (21) are connected with a wire (37). Based on the above structure, the functional requirements of turning around a corner, bearing the wire pressure, preventing the falling of the string, isolating a failure, adjusting the height of a tower and the like can be met. Meanwhile, the twisting problem of link plates can be well solved and the construction cost is lowered. Moreover, the direct jump-through is realized and the construction cost is lowered.

Description

technical field [0001] The invention relates to a hanging tension series connection structure. Background technique [0002] In recent years, with the rapid growth of the national economy, the power industry has developed rapidly, which has promoted the rapid development of the transmission line tower industry. The transmission line tower is a building that supports the conductors and lightning protection lines of high-voltage or ultra-high-voltage overhead transmission lines. There are many types of transmission line towers, which vary with terrain, geology, construction and transportation conditions. The common types of towers are: suspension towers and tension towers. [0003] The tension tower of the transmission line undertakes important functions such as cornering, alignment, bearing the tension of the ground wire, preventing collapse, isolating accidents, adjusting tower height, etc., and has a great relationship with project safety and reliability. The tension towe...
