A device for accelerated corona aging of composite insulator and method of using the same

Abstract

The invention discloses a corona accelerated aging device for a composite insulator, comprising a controller, a processor, a casing, several ground electrodes, needle electrodes and insulating plates,wherein the controller and the processor are both disposed outside of the casing, the ground electrode is composed of two electrode plates with notches, the insulating plate is composed of two insulating plates with notches, the area formed between the notches is used to enclose the rod-like structure between insulator sheds, the insulating plates are disposed at the bottom of the ground electrodes, the needle electrodes are disposed at the bottom of the insulating plates, first electric telescopic rods are disposed between the bottom of the insulating plates and the top of the ground electrodes, a motor is arranged below the casing, an output shaft of the motor passes through the bottom of the casing, the output shaft of the motor is provided with a connecting rod, and the connecting rodis used for connecting the insulating plates located at the bottom of the casing. According to the corona accelerated aging device for the composite insulator and the use method thereof, the all-round aging test of different types of insulators is carried out, and the accurate experimental data of corona aging is obtained, which is convenient for subsequent evaluation of the performance of different types of insulators.

Description

technical field [0001] The invention relates to the field of accelerated aging of insulators, in particular to a device for accelerated aging of composite insulators by corona and an application method thereof. Background technique [0002] The existing corona-accelerated aging devices for composite insulators can only pass the aging test on a certain part of the insulator surface, but in fact, there are many types of insulators, and in the process of manufacturing, the material itself is There are bubbles and gaps and the contact surface (ie interface) between different materials, and the interface is the most dangerous position in the insulator, and the existing aging devices generally cannot pass the aging experiment on the shed of each insulator , so that the performance of insulators manufactured in the same batch cannot be accurately evaluated. Contents of the invention [0003] The problem to be solved by the present invention is a composite insulator capable of pe...
