Live lubricating oil adding device for 10kV overhead line operating mechanism

Abstract

The invention discloses a live lubricating oil adding device for a 10kV overhead line operating mechanism, which comprises a base, a first insulating column and a second insulating column, wherein the first insulating column and the second insulating column are fixed at the upper end of the base, the upper end of the first insulating column is provided with a wire inlet connecting rod, a movable shaft penetrates through the part between two side plates, the two ends, which penetrate through the side plates and extend outwards, of the movable shaft are provided with limiting blocks respectively, a plurality of lubricating notches are evenly formed in the circumferential side wall of the movable shaft in a surrounding mode, an oil can is arranged on the inner wall of the wire inlet connecting rod, an upper end opening of the oil can is communicated with an oil spraying pipe, and the end, which faces the movable shaft, of the oil spraying pipe is connected with a spraying head. The device overcomes the defects in the prior art, is reasonable in design and compact in structure, can spray the jam position through a built-in oil pump, effectively supplements lubricating oil to a disconnecting link operating mechanism in an electrified manner, greatly improves the practicability and safety, and has higher social use value and application prospect.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a live-line lubricating oil device for an operating mechanism of a 10kV overhead line. Background technique [0002] 10kV overhead lines are mainly erected on the ground by poles and towers to transmit and distribute power distribution lines. There are a large number of isolation knife switches and pole-mounted switches on the line, which are used to isolate faults, reduce the scope of power failure damage, and perform switching operations to transfer power supply. With the increasingly lean management of power supply reliability and the management requirements of the provincial company's "four unifications" power grids, the power outages of 10kV overhead lines are widespread, and the maintenance cycle is getting longer and longer. ) The operating mechanism is polluted by the air, the mechanism is rusted, and the transmission is jammed (especially the isolation switch on...

Problems solved by technology

With the increasingly lean management of power supply reliability and the management requirements of the provincial company's "four unifications" power grids, the power outages of 10kV overhead lines are widespread, and the maintenance cycle is getting longer and longer. ) The operating mechanism is polluted by the air, the mechanism is rusted, and the transmission is jammed (especially the isolation switch on the user side has a long service life, insufficient maintenance, and the jamming situation is very prominent)

Once the isolation knife switch operating mechanism has problems such as transmission jamming and inability to operate, it is necessary to cut off the power of the upper-level equipment at this time, expand the scope of power outages, and prolong the operation time, which will have a negative impact on the reliable operation of the equipment and the power supply of the grid; if the isolation operation is forced, The damaged and rusty knife gate is prone to the danger of breaking the supporting porcelain bottle, resulting in a greater range of damage
