Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] see figure 1 , in this embodiment, the upper ends of the left insulator string 8 and the right insulator string 9 of the V-shaped insulator string are installed at different positions of the cross arm 7, and the lower ends of the left insulator string 8 and the right insulator string 9 are connected to the same wire side connecting plate, The wire side connection plate is used to suspend the wire.

[0030] This embodiment is a V-shaped arrangement of compos...

Abstract

The invention discloses a V-shaped arrangement anti-chain-falling treatment and warning method of composite insulators. A suspension member is installed at the middle part of a V-shaped insulator chain and includes a line lightning arrester and a suspension disc type insulator chain that are connected successively. The upper end of the line lightning arrester is connected to a cross arm by a tension sensor; and the lower end of the suspension disc type insulator chain is connected to a wire side linking plate. A data line of an intelligent host is connected to the tension sensor; and information is sent to a device management department by a communication unit. With the disclosed method, the backup protection of the V-shaped composite insulator chain is realized; the lightning protection level of the line is increased; the chain falling probability is reduced; and the lightning trip-out rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a V-shaped arrangement of composite insulators to prevent string dropping and a warning method. Background technique [0002] V-shaped composite insulator strings are widely used in overhead transmission lines in my country. In recent years, string drop incidents have occurred frequently. Dropped strings of composite insulators may not only cause discharge of the conductors to the tower body, but may also cause personal injury if the conductors fall to the ground. For the V-type string, there is no good modification method at present, and the new composite insulators can only be replaced in time according to its operation condition. Contents of the invention [0003] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, one of the objects of the present invention is to provide a V-shaped...
