Embodiment Construction

[0009] According to the rule that the withstand voltage value of the insulator 5 close to the transmission line is high, and the withstand voltage value of the insulator 2 far away from the transmission line 6 is low, the insulator string is formed. There are insulator strings connected in the same way as the tower crosspiece 1 and the line clamp 7.

Abstract

An insulator string characterizes that the pressure-resistant value of each sheet of the insulator is different and the value of the insulator closing to the transmission line is high or it is low on the contrary. The aim of this invention is to reduce the possibility of being broken down one sheet after another to result in flashover matters.

Description

technical field [0001] The invention relates to an insulator string, in particular to an insulator string on an ultra-high voltage transmission line. Background technique [0002] At present, the known insulator strings on the ultra-high voltage transmission line are formed by connecting insulators with the same withstand voltage in series. However, the voltage is not evenly distributed on the insulators, but the voltage of the insulators close to the transmission line is high and may exceed the withstand voltage value, and the voltage of the insulators far away from the transmission line is low. When the voltage of the insulators close to the transmission line exceeds the withstand voltage When the voltage is high, the insulator may be broken down, and thus cause other insulators to be broken down one by one to form a flashover accident. Contents of the invention [0003] In order to overcome the disadvantage that the unreasonable combination of insulators in the existin...
