The device is helpful to searching for trouble points and judging whether the operating status of the area insulation components is desirable or not; the utility model is complement and perfection for the existing monitoring and checking equipment of the electrified railway, and plays an important role in transport operation and repair of the electrified railway and guarantee for safe power supply.
Description
Technical field
The utility model relates to a kind of insulator arc-over and punctures indicator.
Background technology
Current, the protective ground of electrification railway contact net adopts aerial earth wire to concentrate earthing mode more, and the section that some adopt catenary mast list earthing mode has also carried out the aerial earth wire transformation or.Aerial earth wire concentrates earthing mode to reduce fragile the losing of single earthing mode ground wire, and the interference when electricity affair track signal circuit and worker be engaged in the circuit trimming, and result of use is better.After but aerial earth wire concentrates earthing mode also to bring insulator arc-over, puncture, search the relatively problem of difficulty of trouble spot.Break down after the tripping operation, the ground patrolman need search insulator successively, and change according to it and judge its state, with the localization of faults, time-consuming, effort; The insulator that has since the path that flashover takes place in the above, the ground staff is difficult to find because the visual angle is limit, and is just difficult more when searching in night or the tunnel.Thereby, can not in time find the trouble spot, cause the time-delay of breakdown repair.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of insulator arc-over simple in structure, that help to search trouble spot and judgement region insulation parts duty quality rapidly and punctures indicator.
The technical scheme in the invention for solving the above technical problem is:
Insulator arc-over punctures indicator, it comprises shell and is located at wire jumper on the shell, iron core, armature, the involution button, direction board, messenger wire, interior bearing, reaction spring, compressing tablet, involution button axle is formed, iron core is 2 half slots, block wire jumper, pass through bolt, closed, armature one end hangs on the interior bearing, the other end links to each other with involution button linkage assembly, the involution button is fixed on the built-in axle, one end bears down on one to compressing tablet by connecting rod, on the bearing, is provided with reaction spring in the middle of it in compressing tablet one end hangs over, the other end is pressed on the direction board, and the direction board other end is connected on the shell by messenger wire.
Described direction board is the fluorescence board.
The technical progress that the utility model is obtained is: the utility model is by after being installed on catenary mast ground wire and the aerial earth wire tie jumper, in case after certain support insulator generation flashover, the puncture, short-circuit current is by the indicator primary side, indicator motion, and provide the board signal, the patrolman just can be local discovery the far away, takes advantage of hidden danger and fault that the inspection of railcar or locomotive just can faster discovery insulating element, just can in time obtain regulation and rush to repair recovery.Because direction board is the fluorescence board, inspection is also very convenient in night or tunnel.This device helps the judgement with region insulation parts duty quality of searching of trouble spot, is the replenishing of existing electric railway service observation equipment, perfect, in the electric railway operation, overhaul, guarantee to have brought into play on the safe power supply great function.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an installation site of the present utility model synoptic diagram.
Among the figure, 1-wire jumper, 2-iron core, 3-armature, 4-involution button, 5-shell, 6-direction board, bearing in the 7-messenger wire, 8-, 9-reaction spring, 10-compressing tablet, 11-involution button axle, 12-aerial earth wire, 13-ground wire wire jumper, 14-indicator, 15-insulator.
Embodiment
As Fig. 1, embodiment shown in 2 as can be known, insulator arc-over punctures indicator, it comprises shell 5 and is located at wire jumper 1 on the shell 5, iron core 2, armature 3, involution button 4, direction board 6, messenger wire 7, interior bearing 8, reaction spring 9, compressing tablet 10, involution button axle 11 is formed, iron core 2 is 2 half slots, block wire jumper 1, pass through bolt, closed, armature 3 one ends hang on the interior bearing 8, the other end links to each other with involution button 4 linkage assemblys, involution button 4 is fixed on the built-in axle, one end bears down on one to compressing tablet 10 by connecting rod, on the bearing 11, be provided with reaction spring 9 in the middle of it in compressing tablet 10 1 ends hang over, the other end is pressed on the direction board 6, direction board 6 other ends are connected on the shell 5 by messenger wire 7, are the fluorescence board on the direction board 6.
Its principle of work is as follows: after as Fig. 2 this indicator being installed, when in the wire jumper during no short-circuit current, armature is in shown position, direction board by pressure board in indicator.When having short-circuit current to flow through in the wire jumper (greater than 200A), around wire jumper, produce magnetic field, under the effect of magnetic field force, armature is by adhesive, and direction board splits away off in the indicator and provides the board signal under its action of gravity, owing to fall board and hung by messenger wire, can not fall to ground, be hung in the air, easily be found by the patrolman.Behind indicator motion, when the contact net interruption maintenance, can manually direction board be put into indicator, press reset button simultaneously, be fixed in the indicator, in order to action next time.Adjust the gap between iron core and the armature, can make action current find to change, generally adjust,, its stationkeeping is got off, generally can satisfy the needs of all location action currents by calculating and test according to the terminal minimum short-circuit current of supply arm.
