Abstract
The utility model relates to a short circuit fault displaying device which belongs to transmission engineering and is suitable for the fault type of power supply circuits of various breakers. The purpose of the utility model is to provide a display device which can distinguish the cutting of a breaker caused by short circuit faults. The device is additionally arranged on an armature iron f which is arranged on the breaker and slides by the magnetic force of an original coil e (or an overcurrent parasitic inductance line segment j of a power supply conducting wire) and is composed of a transmission rod 7, a slide block 1, a display block 2 and a spring 3. The utility model makes the maintenance of breakers convenient.
Description
The utility model belongs to power transmission engineering, and suitable reinforcement is contained in the display device of the feed circuit fault type on the various isolating switchs.
At present, domestic commercially available isolating switch normally adopts additional coils or electric power conductor overcurrent stray inductance to add the electromagnet of armature, makes the contact adhesive in the isolating switch and the electromechanical structure of disconnection.When circuit load short circuit or overload, the power supply contact of isolating switch is thrown off and is made the isolating switch outage, then turns off electric.Yet but non-fault reason (short circuit or overload) clearly shows, makes troubles to maintenance.
It is the display device of load short circuits that the utility model purpose is to provide a kind of power supply contact that can distinguish isolating switch to throw off reason.
The utility model purpose is achieved in that
A kind of short trouble display device, it is characterized in that being installed on the isolating switch, on the original armature f that leans on the magnetic force of original coil e (or electric power conductor overcurrent stray inductance line segment j) and slide, by drive link 7, the short trouble display structure that slide block 1 and displaying block 2 and spring 3 are formed; Slide block 1 is installed in the garden type guide rail of orthogonal two track chassis 5, and displaying block 2 and spring 3 are installed in the T type guide rail by left-to-right successively, and chassis 5 is contained in and has on the insulcrete 4 of being convenient to displaying block 2 sliding channels; Armature f moves down because of short trouble, drives the drive link 7 and the slide block 1 that flexibly connect by pin (6.8) order and moves down, and displaying block 2 promotes by spring 3, holds void and moves to left and fill up the slide block room, and show with " short circuit " two words that are carved with on it; The section of described displaying block 2 is the T font, and the leptoprosopy that is carved with " short circuit " two words is in insulcrete 4 grooves, and wide in the T on chassis 5 type guide rail; Make by the good material of insulating property on described slide block 1, displaying block 2, insulcrete 4 and chassis 5.
In conjunction with the accompanying drawings, further specify the utility model content.
Fig. 1 the utility model is installed in the structural drawing on the coil electromagnetism swage isolating switch
Fig. 2 the utility model is installed in the structural drawing on the electric power conductor stray inductance type isolating switch
Identifier is as follows among the figure:
1 slide block, 2 displaying blocks, 3 springs, 4 insulcretes, 5 chassis
8 times pins of pin 7 drive links on 6
A back-moving spring b dropout semiaxis b1 electric power conductor c spring
E coil f moving armature i armature j lead
Fig. 1 is that the utility model is installed in the structure chart on the coil electromagnetism swage breaker. Lower-left figure shows with small letter English matrix Coil e, armature f, dropout semiaxis b and current supply line b1 are former breaker structures; The picture left above is additional with utility model Short trouble type display device structure, right figure is the side view of the utility model A-A section.
In the upper end of the original electromagnet armature f of breaker, be flexibly connected with lower pin 8 and drive link 7 lower ends; Drive link 7 The upper end is used pin 6 with slide block 1 and is flexibly connected, and the right side of slide block 1 is followed successively by T-shaped displaying block 2 Hes that fault category shows Compress Spring 3. There are mutually perpendicular garden type and 2 T-shaped guide rails in chassis 5, garden type guide rail splendid attire slide block 1, and T-shaped guide rail is contained Dress displaying block 2. Envelope has the insulation board 4 of with groove above chassis 5. The groove of insulation board 4 just is suitable for 2 quarters of displaying block There is the leptoprosopy of " short circuit " two words to slide.
When the momentary load short circuit current flow through coil e, coil magnetic force that e produces attracted armature f to move downward, and drives Slide block 1 glides; Displaying block 2 promotes the bottom left bullet at spring 3, just fills up the room of slide block 1; So, on the displaying block 2 " short circuit " two words expose at the groove left part of insulation board 4.
Meanwhile, pressing spring C under the armature f threads off dropout semiaxis b and current supply line b1. This moment, breaker was in shutoff State waits for that operating personnel process.
Pick up repair after, the artificial right side pushes away displaying block 2, slide block 1 with armature f under spring C promotes on move and reset, the semiaxis b that threads off simultaneously diminishes because of the pressure of spring C, by spring a pulling, withholds again on electric power conductor b1, the result presents normal power supply again.
Fig. 2 is that the utility model is installed in the structural drawing on the electric power conductor stray inductance type isolating switch.Lower-left figure produces the electric power conductor j of stray inductance circuit, armature i, and dropout semiaxis b, electric power conductor b1 are former breaker structures; The picture left above is the additional short trouble type display device structure of the utility model, and is identical with Fig. 1 the picture left above.
When load short circuit current flow through electric power conductor j, its parasitic overcurrent inductance produced magnetic force, attracted armature i downward, and drive link 7 and slide block 1 repeat the described action of Fig. 1, and final displaying block 2 exposes at the groove left part of insulcrete 4.Meanwhile, dropout semiaxis b and electric power conductor b1 thread off, and isolating switch is in off state, and etc. pending fault pick up and repair.
After the same maintenance, the artificial right side pushes away displaying block 2, and dropout semiaxis b is buckled on the electric power conductor b1 service restoration again by drawing on the spring a.
The utility model advantage:
Short trouble and cause that fault type that various isolating switchs turn-off has and clearly show brings convenience to the maintenance personal.
Embodiment 1
The utility model is installed on the isolating switch of coil electromagnetism swage, promptly presses Fig. 1 assembling.Through using, display effect is obvious, and is easy to maintenance.
Embodiment 2
The utility model is installed on the isolating switch of electric power conductor stray inductance type, presses Fig. 2 assembling.Through using, display effect is obvious, and is easy to maintenance.
