Problems solved by technology

However, the existing technology currently used is to lengthen the length of the insulator string to increase the flashover voltage. This method requires the abolition of the original tower and then re-erecting the tower, and even requires increasing the size of the tower window and increasing the area occupied by the line corridor.
As a result, the cost of transformation will be high, making it very complicated and difficult to operate, and it cannot be fully and effectively carried out on the power grid, so it cannot be used to protect the operation safety of the power grid

Abstract

The invention discloses an indirectly inserted ice flashover resistant insulator which consists of a second hardware fitting (6), a panel (1), a first composite insulator (21), a first glass insulator (31), a second composite insulator (22), a second glass insulator (32), a third compound insulator (23), a third glass insulator (33), a four composite insulator (24), an equalizing ring (4) and a first hardware fitting (5) which are coaxially connected in serial in sequence. The diameter of the sectional circle of the panel (1) is larger than that of the diameter of the sectional circle of the equalizing ring (4). When the insulator is used, the insulator is arranged on a tower for suspending a lead wire. The insulator has the advantages of preventing rainwater, ice and snow, bird manure and water screen, reducing dirty degree, delaying ice coating time, improving anti-icing effect, improving the electrical field distribution of the earth level end of the insulator, increasing the flashover voltage and playing a protection role in lightning stroke, as well as reducing the window size of the tower and a line corridor, and saving the construction investment.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to an intercalated anti-icing flashover insulator used for delaying the bridging time of ice-coated icicles and improving the ice-coated power frequency flashover voltage. Background technique [0002] In recent years, severe accidents of insulator flashover and tripping of transmission lines caused by icing have occurred frequently, which not only caused huge economic losses, but also seriously affected the safe operation of the power grid and the normal life of the people. Therefore, it is necessary to delay the bridging time of icing and ice slug and increase the flashover voltage of ice-covered power frequency when the transmission line forms icing, which is very necessary to ensure the safe operation of the transmission line. However, the existing technology currently used is to lengthen the length of the insulator string to increase the flashover vol...
