Abstract

Provided is a guano propulsion device of overhead transmission lines. The guano propulsion device comprises an air compressor (1), a pneumatic diaphragm pump (2), a guano filling container (3), a rubber pipe, a spray nozzle (15), a (rubber) air pipe D (12), a (rubber) air pipe B (9), a (rubber) air pipe A (5), a solenoid valve (4), an air pipe C (11) and an air pressure pusher (13). The beneficial effects are that 1) it can be achieved that the guano propulsion device is highly automatic; 2) electric isolation between operators and a high-voltage end can be achieved and safety of the operators is ensured; and 3) precision and rationality of tests are ensured and the tests are largely consistent with the actual condition, the guano propulsion device can be widely applicable in research tests of bird damage mechanisms of transmission lines and basis is provided for selection and verification of outer insulation of the transmission lines of an electric system.

Description

technical field

[0001] The utility model belongs to the technical field of auxiliary devices for the safe operation of overhead transmission lines, and specifically relates to a bird droppings propelling device in a system for detecting the discharge characteristics of a transmission line-crossarm under the action of bird droppings. Background technique

[0002] At present, with the strengthening of human environmental protection, the number of birds is gradually increasing, and the scope of activities is expanding day by day. Bird tripping faults in overhead transmission lines of power systems are becoming more and more prominent, which seriously affects the safe operation of overhead transmission lines. According to the analysis, there are four types of bird damage faults on overhead transmission lines: ① When the bird spreads its wings and flies, the body short-circuits the air gap and causes a short-circuit fault; Pollution on the surface of insulators leads to flashover...
