Abstract

Disengaging gear is locked the present invention relates to a kind of drainage thread of rapid arc extinction, it includes insulating bar, eccentric shaft and clamp, insulating bar is fixedly connected by connecting rod with eccentric shaft, described clamp is L-shaped, the connection end of L-shaped clamp is arranged in connecting rod by rod set, rod set is rotated with connecting rod and is connected, and the working end of L-shaped clamp is parallel with eccentric shaft, and the upper surface of clamp working end is provided with circular arc wire grooves.The setting that the present invention passes through clamp and eccentric shaft, wire is put into wire grooves, when one side of the eccentric shaft away from axial line is rotated to clamp upper surface, eccentric shaft diminishes with clamp gap, it is possible to achieve the quick locking of wire, when the one side that eccentric shaft closes on axial line is rotated to clamp upper surface, eccentric shaft becomes big with clamp gap, it is possible to achieve wire departs from, so as to rapid arc extinction, prevent electric arc from elongating and causing the problem of drainage thread discharges, suitable in narrow space application.

Description

The drainage thread locking disengaging gear of rapid arc extinction
Technical field
The invention belongs to electric power transmission power transformation technology field, the drainage thread locking of more particularly to a kind of rapid arc extinction disengages dress Put, it is adaptable to transmission line of electricity and transformer station's live-line maintenance operation.
Background technology
During 220kV-66kV Operation of Electric Systems with maintenance livewire work, it is often necessary to which operating personnel carries out powered Cut off trouble point, drainage thread cut off using insulation cutter, it is in the past powered it is disconnected draw during, use multiple insulated lock levers, 3-4 people coordinates Drainage thread is fixed, consumption rope is connected on drainage thread, arranges extinguishing arc measure, cut drainage thread with insulation conductor cutter, Gu Determining drainage thread needs manpower, instrument more, and operation is unfavorable in shaft tower small space, and it is long to often result in the extinguishing arc time, and arc light is big, There is potential safety hazard, easily increase operator's psychological burden, unfavorable to overall operation.
The content of the invention
The present invention disengages dress for above-mentioned problems of the prior art there is provided a kind of locking of the drainage thread of rapid arc extinction Put, solve the problem of drainage thread fixation needs manpower, instrument is more in the prior art.
Technical scheme is as follows:
A kind of drainage thread locking disengaging gear of rapid arc extinction, including insulating bar, eccentric shaft and clamp, insulating bar pass through connecting rod Be fixedly connected with eccentric shaft, described clamp is L-shaped, the connection end of L-shaped clamp is arranged in connecting rod by rod set, rod set with Connecting rod rotates connection, and the working end of L-shaped clamp is parallel with eccentric shaft, and the upper surface of clamp working end is recessed provided with circular arc wire Groove.
Described clamp is provided with the fixing bolt for being used for fixing extinguishing arc rope.
Described circular arc wire grooves are provided with multiple, the internal diameter of multiple circular arc wire grooves.
Deck is provided between described insulating bar and clamp, deck is fixedly connected in connecting rod.
The termination of described connecting rod is provided with grafting neck, and the outer surface of connecting rod is circumferentially arranged with circumferential bayonet slot.
The invention has the advantages that:
By the setting of clamp and eccentric shaft, wire is put into wire grooves, when one side of the eccentric shaft away from axial line rotate to During clamp upper surface, eccentric shaft diminishes with clamp gap, it is possible to achieve the quick locking of wire, when eccentric shaft closes on axial line When simultaneously rotating to clamp upper surface, eccentric shaft becomes big with clamp gap, it is possible to achieve wire departs from, so as to quickly disappear Arc, prevents electric arc from elongating and causing the problem of drainage thread discharges.The present invention powered on transmission line of electricity can not only be used, can be with In narrow space application.

Embodiment
Embodiment
As illustrated, a kind of drainage thread locking disengaging gear of rapid arc extinction, including insulating bar 9, eccentric shaft 7 and clamp 6, insulation Bar 9 is fixedly connected by connecting rod 8 with eccentric shaft 7, and described clamp is L-shaped, and the connection end of L-shaped clamp is installed by rod set 3 In connecting rod, rod set is rotated with connecting rod and is connected, and the working end of L-shaped clamp is parallel with eccentric shaft, the upper table of clamp working end Face is provided with circular arc wire grooves 5, and circular arc wire grooves are provided with multiple, the internal diameter of multiple circular arc wire grooves, it is adaptable to The wire of multiple diameter is applicable;Described clamp is provided with the fixing bolt for being used for fixing extinguishing arc rope, overcomes extinguishing arc rope and passes through The modes such as binding are connected to cumbersome on drainage thread.
Deck 4 is provided between described insulating bar and clamp, deck is fixedly connected in connecting rod;Described connecting rod Termination is provided with grafting neck 1, and the outer surface of connecting rod is circumferentially arranged with circumferential bayonet slot 2, and insulating bar passes through grafting neck 1 and circumference Neck 2 is with after the raised fastening inside insulating bar, being fastened by bolts, while the end face of insulating bar is touched with deck.
Exemplified by cutting drainage thread, in use, drainage thread is put into wire grooves, rotating insulated bar, so as to drive partially Heart axle rotates, and when one side of the eccentric shaft away from axial line is rotated to clamp upper surface, eccentric shaft diminishes with clamp gap, can be with Realize the quick locking of drainage thread;After end-of-job, the rotating insulated bar of opposite direction, when eccentric shaft closes on the one side rotation of axial line When going to clamp upper surface, eccentric shaft becomes big with clamp gap, it is possible to achieve drainage thread departs from.
