Description
Technical field
The present invention relates to breaking insulator fields, and in particular to a kind of arc-control device based on section insulator.
Background technique
Important equipment of the section insulator as the same mutually electricity segmentation of contact nets in electrified railways, when overhaul of the equipments or occurs event
When barrier, scope of power outage can be reduced, reduce the interference to transport, be widely used in marshalling yard, engineering reorganizes and outfit field, Passenger Transport Hub and
Two-wire electric railway.Section insulator has become one of key equipment of rail transportation system, and whether section insulator is safe
Stable operation has become an important factor for contact net safe power supply.When block of bow collector of electric locomotive passes through section insulator, to cut
The disconnected electric current from the last period contact net, and section insulator both end voltage reaches as high as thousands of volts, passes through the electricity generated herein
Arc is often not easy to extinguish, and the high temperature ablation effect of electric arc is in segmentation often under unfavorable operating condition.In existing segmentation
In insulator design, only the striking effect of arcing horn is not enough to limit the high voltage at arcing horn both ends and the electricity of high current
Arc arcing, the electric arc that pantograph is generated by section insulator for a long time act on the ablation of section insulator, have threatened traction
The safety of power supply system.And with the current situation of electric railway high-speed high-power, breaking insulator both end voltage electric current
Also it is being gradually increased, this makes traditional breaking insulator arcing horn success blow-out increasingly difficult.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of arc-control device based on section insulator, particular techniques
Scheme is as follows:
A kind of arc-control device based on section insulator, including suspension line, setting are slided on suspension line and with suspension line
The linear actuator of connection, the grizzly bar group that linear actuator output end is set and the control group being connect with linear actuator,

Arc extinguishing grizzly bar is equipped with fixed frame and the spacing of adjacent arc extinguishing grizzly bar is gradually increased along the direction close to linear actuator, recruits arc
The spacing at angle is also gradually increased along the direction close to linear actuator.
In the present invention when pantograph passes through breaking insulator, due to arcing horn both ends high voltage and high current, often
Electric arc generation is had to be pulled open by arcing horn one end with pantograph pan with the movement of pantograph pan after electric arc generation.Work as cunning
When plate is close to the arcing horn other end, electric arc is transferred to other side arcing horn under heat buoyancy effect.In transfer process electric arc into
Enter in grizzly bar group, electric arc is cut into sectional short arc by arc extinguishing grizzly bar, and every section of electric arc is in arc extinguishing grizzly bar heat buoyancy and magnetic
It is up moved under field action.When control group monitors that there is electric arc generation at arcing horn both ends, control group controls linear actuator and draws
Moving grid item group up moves.During the upward movement, grizzly bar group both ends are gradually increased grizzly bar group at a distance from arcing horn, are made simultaneously
Whole constantly up move of electric arc is obtained to be elongated and weaken its arcing intensity.
Preferably, control group includes and the picture monitor for recruiting arc bar to connect and the PLC connecting with linear actuator
The signal input part of controller, PLC controller is connect with picture monitor.
When picture monitor monitors that there is electric arc generation at arcing horn both ends in the present invention, picture monitor will control signal and pass
Defeated to arrive PLC controller, PLC controller control linear actuator pulls grizzly bar group up to move.Grizzly bar group during the upward movement,
Judging whether electric arc extinguishes by picture monitor, the grizzly bar group position reset if arc extinction, preparation acts next time, if
Do not extinguish, stops after continuing to move to grizzly bar group up to its threshold value.
Preferably, picture monitor includes voltage monitor and current monitor.
The present invention is monitored arcing horn by voltage monitor and current monitor, improve monitoring efficiency and
Monitoring precision.
Preferably, arcing horn includes bottom bar and sets between the trick arc bar of bottom bar rotation connection, bottom bar and trick arc bar
There is the line handspike connecting with PLC controller.
The present invention grizzly bar group during the upward movement, PLC controller control line handspike rotation recruit arc bar, make bottom bar with
It recruits the angle between arc bar constantly to reduce, so that grizzly bar group both ends are gradually increased at a distance from trick arc bar, improves arc extinguishing effect
Rate.
Preferably, line handspike fixing end is fixedly connected with bottom bar, the output end of line handspike and the fixed company of trick arc bar
It connects.
The present invention is pulled by driving line handspike recruits arc bar to make that arc bar is recruited rotate around bottom bar, adjust recruit arc bar and bottom bar it
Between angle, and then adjust the distance between grizzly bar group both ends and arcing horn.
Messenger wire is adjusted preferably, being equipped between linear actuator and grizzly bar group.
Preferably, the shape of arc extinguishing grizzly bar is the material that uses of cylindrical body and arc extinguishing grizzly bar for high temperature resistant anti-ablation material
Material.
The invention has the following advantages:
Electric arc enters grizzly bar group in transfer process in the present invention, and electric arc is then cut into sectional short by arc extinguishing grizzly bar
Arc, and when every section of electric arc up moves under arc extinguishing grizzly bar heat buoyancy and magnetic fields, adjacent arc extinguishing grizzly bar is opened away from work
With enabling electric arc is more rapid to extinguish, improve arc extinguishing efficiency.Simultaneously when control group monitors that there is electric arc at arcing horn both ends
When generation, control group control linear actuator pulls grizzly bar group up to move.Grizzly bar group during the upward movement, grizzly bar group both ends
It is gradually increased at a distance from arcing horn, while electric arc being made integrally constantly up to move and gradually weaken, further improved and go out
Arc efficiency.
The present invention passes through the mobile expansion graded insulation of grizzly bar group on the basis of ensure that arcing horn horizontal space is certain
The longitudinal space of device extinguishes electric arc by the expansion in space, ensure that arcing horn not by prolonged arc erosion, final guarantor
The safe operation of tractive power supply system and train is hindered.On the basis of guaranteeing arcing horn horizontal space, trick arc is taken full advantage of
Angle longitudinal space goes to dissociate to enhance electric arc, reduces erosion and heat effect of the electric arc to electrode, protects section insulator
Equipment has ensured the safe operation of bullet train.Present device is succinct independent simultaneously and moves disassembly, is easily installed and makes
