Problems solved by technology

[0003] When the insulator string is connected, it is necessary to connect the insulator string to multiple high-voltage lines. However, there is only a single connection ring structure at both ends of the insulator string, which makes the connection range of the insulator string small, and the connection and fixing are inconvenient, and the simple connection ring Easy to slip off, the connection is not strong

Abstract

The invention relates to the technical field of high voltage equipment, and specifically discloses a triple strain insulator string used for an ultra-high voltage transmission line. The triple straininsulator chain comprises mounting plates, connecting plates, limiting tubes, insulation strings, rotating mechanisms, supporting mechanisms, drawing mechanisms and connecting columns. Three-positionadjustment of connecting rings in the transverse direction, longitudinal direction and vertical direction can be adjusted through the rotating mechanism, the supporting mechanism and the drawing mechanism, so that the connecting rings can be connected with a high voltage line more conveniently, and the connecting range of the connecting rings is improved greatly; through mutual cooperation of locking plates and limiting grooves, rapid sleeve joint of the connecting plates and the insulation strings can be realized, first locking teeth face the connecting plates outwards slantly, second lockingteeth face the insulation strings inwards slantly, after the locking plates are engaged slidably, the locking plates cannot be pulled out, through the combined action of the locking teeth and first locking bolts, the connecting strength of the connecting columns and the limiting tubes can be improved greatly, and the insulation strings are avoided from falling off.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment, in particular to a triple tension insulator string for extra-high voltage transmission lines. Background technique [0002] The insulator string refers to the combination of two or more insulator elements, and the assembly of the flexible suspension wire; the insulator string is a protective device with fixing and operation requirements, which is used to suspend the wire and insulate the wire from the tower and the earth, and is used in the transmission line In the insulator string, the assembly type of the insulator string is different due to the difference in the structure of the tower, the structure of the insulator, the size of the wire, the number of sub-wires for each phase, and the voltage level. [0003] When the insulator string is connected, it is necessary to connect the insulator string to multiple high-voltage lines. However, there is only a single connection ring stru...
