Problems solved by technology

Also, the tensile strength and breaking load of the polymer insulation in the event of a fire were not measured
Because the test device and method are complex and difficult to operate, the reliability test of polymer insulators based on temperature changes is not performed
Therefore, the reliability of polymer insulators is severely reduced in Korea

Abstract

A device for forest fire simulation test of a polymer insulator is provided, which comprises a heating unit arranged below the polymer insulator that is positioned inside a heating furnace to supply a heating source; a stretching force supply unit arranged collinearly to the polymer insulator and used to supply the polymer insulator with a stretching force when the corresponding end of the polymer insulator is fixed to a fixation clamp; a stretching force measuring unit for measuring the stretching force applied to the polymer insulator, the stretching force measuring unit comprising a dynamometer that is used to convert a dependent variable of the polymer insulator produced by the stretching force supply unit to a resistance to measure loads, and is arranged in the same line as the stretching force supply unit and positioned behind thereof, and a data storage / output unit for storing and output temperature values of the heating unit and data values measured by the stretching force measuring unit.

Description

technical field [0001] The present invention relates to a forest fire simulation test device for polymer insulators, and more particularly, to a polymeric insulator that can simultaneously measure and test the fire resistance and tensile force of polymer insulators used on power transmission lines A forest fire simulation test device for physical insulators, which can simulate fire conditions and put the polymer insulator body under simulated fire conditions, thereby inferring the performance and load of the polymer insulator, replacing or repairing the polymer insulator , and thus avoid accidents and loss of resources, life and property. Background technique [0002] Typically, nearly 99% of insulators used in Korea are ceramic insulators. On the other hand, polymer insulators are increasingly used in other countries due to their low cost, ease of installation and light weight. For this reason, the use of polymer insulators has come under scrutiny in South Korea. However...
