Abstract

An insulation spraying device for an overhead bare wire comprises two suspenders arranged on a travelling hanger (6). Travelling wheels are arranged at head portions of the two suspenders; the travelling wheels travel on the overhead bare wire (1) through travel grooves on wheel faces; an output shaft of a traction motor (8) is mechanically connected to an input end of a gear transmission mechanism (9), and an output end of the gear transmission mechanism is meshed with a driving gear that is fixedly arranged on a front wheel shaft (4). A dovetail support (17) is fixedly arranged at the rear end of the travelling hanger, and an insulating paint nozzle (18) is arranged at both tail ends of the dovetail support. The device uniformly sprays insulating paint on the overhead bare wire by using a pneumatic mechanism, thereby solving the wire-tree contradiction, avoiding the electricity stealing, reducing the cost, and lowering the construction difficulty.

Description

technical field [0001] The invention relates to a device for insulating and spraying bare wires of power transmission lines in a power system. Background technique [0002] The overhead lines of urban and rural power grids generally use bare wires as the carrier of power transmission. However, in some rural areas, it is common for users to illegally hang wires on the bare wires to steal electricity. At the same time, when the transmission line corridor passes through the forest, there are tree lines. Contradictory issues. The existing technology is to solve the above problems by replacing the bare wires with insulated wires, but this method has problems such as large investment, long construction period, and obstruction of line reconstruction projects. Contents of the invention [0003] The invention provides an overhead bare wire insulation spraying device, which solves the problems of large investment, long construction period, and obstruction of line reconstruction pr...
