Simulation insulator string suspension fitting

Abstract

The invention discloses a simulation insulator string suspension fitting for suspending a simulation insulator string above which a suspension shaft is arranged. The simulation insulator string suspension fitting comprises a clamping handle and a hook main body, wherein the hook main body comprises a fastening mechanism and a fishhook-shaped hook body; the clamping handle comprises a clamping head and an operating rod; a limiting clamping tongue extends from the clamping head to the operating rod; a first limiting part is arranged on the outer surface of the clamping head; a first limiting matching part clamped together with the first limiting part is arranged on the upper part of the hook body; the clamping handle is hinged to the hook main body; when the clamping handle rotates about a hinge point between the clamping handle and the hook main body till the first limiting part is clamped together with the first limiting matching part, the suspension shaft is limited in the hook main body through the limiting clamping tongue. By adopting the structure, the simulation insulator string suspension fitting has the advantages of convenience and rapidness in installation and detachment, safety, reliability and high robustness.

Description

technical field [0001] The invention belongs to power transmission and transformation construction tools, in particular to a simulated insulator string suspension fitting. Background technique [0002] Transmission lines have been exposed to the wild for a long time, and the on-site operating environment is constantly changing, especially in the southern warm and humid tropical and subtropical monsoon climate conditions. The pollution of the external environment can easily lead to pollution flashover trips, which seriously threaten the safe, stable and reliable operation of the line. . In order to fully understand the pollution situation in the area where line insulators pass through and grasp the relevant anti-pollution data, simulated string insulators are usually hung on the pole tower, and the pollution level of the surface of the insulator string is simulated to determine the environmental pollution level, formulate or revise the pollution area of ​​the power system Di...

Problems solved by technology

Alternatively, use a salt-dense sampling towel to directly wipe the simulated insulator strings tied with iron wires on the tower, but this method requires wiping and sampling at high altitudes, which will eventually lead to large deviations in measurement results

The traditional installation method is cumbersome and has great potential safety hazards. Due to the complex operating environment of the line, the iron wire is easy to rust and disconnect, which can easily cause insulators to fall and cause injuries.

Moreover, once the iron wires are rusted and scattered in the traditional installation method, it is easy to reduce the insulation distance of the lines and cause short-circuit discharge of the lines.
