Suspension device and application method of equivalent salt deposit density insulator

Abstract

The invention relates to a suspension device of an equivalent salt deposit density insulator. The suspension device comprises an equivalent salt deposit density insulator suspension plate and a fixing bolt assembly, the equivalent salt deposit density insulator suspension plate is of an integrally-formed n-shaped structure, a lifting lug is arranged on the upper portion of the equivalent salt deposit density insulator suspension plate, a suspension hole used for suspending an insulator string is formed in the lower portion of the equivalent salt deposit density insulator suspension plate, a plurality of transversely through fixing holes are formed in the middle of the equivalent salt deposit density insulator suspension plate, and the fixing bolt assembly is fixed in the corresponding fixing holes so that the equivalent salt deposit density insulator suspension plate and an iron tower crossarm can be relatively fixed. The application method includes the step that the fixing bolt assembly is combined with the corresponding fixing holes to be fixed. Compared with the prior art, the suspension device and the application method have the advantages that galvanized parts are adopted, strength is high, and corrosion resistance is good; the suspension device can be used for iron tower crossarms of various specifications, can be flexibly adjusted according to situations, and is convenient to use and firm and reliable in connection; the lifting lug is arranged on upper portion of the suspension plate, so that installation and adjustment are facilitated; machining is convenient, manufacturing cost is low, the labor intensity of operating personnel can be relieved, installation efficiency is improved, application prospects are broad, and promotion value is enormous.

Description

technical field [0001] The invention relates to a salt-tight insulator suspension device for an electric power system, in particular to a salt-tight insulator suspension device and a using method thereof. Background technique [0002] Pollution flashover of transmission line insulators is one of the main factors that threaten the safe operation of power systems. In recent years, with the rapid development of my country's economy, the environmental pollution in some areas has become increasingly serious, and the resulting pollution flashover accidents in the power system have also become increasingly serious. By testing salt-dense insulators, the pollution situation in the area can be determined, and on this basis, the distribution map of the polluted area of ​​the power system can be drawn, so that the type and length of the insulator string can be reasonably selected to prevent transmission line insulators from flashover. At present, salt-dense insulators are widely used o...

Problems solved by technology

The conventional salt-dense insulator suspension method is to fix the metal fittings of the salt-dense insulator string to the cross-arm of the iron tower through 8# iron wire. Since the 8# iron wire is very prone to rust and breakage, and it is difficult to bind and fix it in high-altitude operations, the conventional method is adopted. The fixation method has shortcomings such as irregular operation, poor suspension stability, and easy to cause hidden dangers.
