Abstract

The invention discloses a telescopic suspension insulator string, which comprises insulators. The insulators are arranged on a telescopic rod and internally provided with connection sleeves, the insulators are mounted on the telescopic rod through the connection sleeves, and the telescopic rod comprises an internal threaded connection rod and an external threaded connection rod. Two ends of the internal threaded connection rod are provided with connection grooves, two ends of the external threaded connection rod are in threaded connection in the connection grooves in two ends of the internal threaded connection rod, and the connection sleeves of the insulators are connected to an external surface layer of the internal threaded connection rod. The telescopic suspension insulator string hasadvantages that the telescopic rod is formed by the internal threaded connection rod and the external threaded connection rod, two ends of the internal threaded connection rod are provided with the connection grooves, the external threaded connection rod is in threaded connection with two ends of the internal threaded connection rod, a contact area of the external threaded connection rod and the connection grooves is changed by rotating of the external threaded connection rod, and accordingly length of the telescopic rod can be adjusted, and telescopic adjustability of the suspension insulatorstring is realized.

Description

technical field [0001] The invention relates to an insulator string, in particular to a stretchable suspension insulator string. Background technique [0002] An insulator string refers to an assembly of two or more insulator elements combined to flexibly suspend conductors. The insulator string is a protective device with fixed and operational needs, which is used to suspend the wire and insulate the wire from the tower and the earth. The insulator string is used in the transmission line. 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 per phase, and the voltage level, the assembly type of the insulator string is different. It can be divided into two categories: suspension insulator string and tension insulator string. [0003] The suspension insulator strings are easily disturbed by birds during use. When the birds stay, it is easy to cause the danger of tripping. Moreover, after the exist...
