Abstract
The utility model relates to a short circuit fault displaying device which belongs to transmission engineering and is especially suitable for trippers of various breakers. The purpose of the utility model is to provide a display device which can distinguish the cutting of breakers caused by short circuit faults. The displaying device is mainly composed of a driving rod 5, a spring 4 and a display block 3. The utility model has obvious effect and convenient maintenance through use.
Description
The utility model relates to a kind of short trouble display device, is specially adapted to the electrical apparatus release of various isolating switchs.
The electrical apparatus release of selling on the domestic existing market is a kind of mainly by coil, iron core; Another kind mainly is made up of parts such as bus, armature.When the instantaneous short circuit electric current flows through coil or bus, produce magnetic field, attract iron core or armature, electrical apparatus release is threaded off, isolating switch disconnects; Can but circuit overloads also make isolating switch cut-off, and is which kind of fault disconnects isolating switch actually? in the prior art field, also there is not a kind of display device.
The purpose of this utility model is that a kind of display device will be provided, and it can be distinguished is to cut-off owing to short trouble causes isolating switch.
The purpose of this utility model is achieved in that
A kind of short trouble display device is characterized in that installing one by drive link 5 from existing electrical apparatus release, spring 4, displaying block 3, chassis 2, the short trouble display device that installing plate 1 is formed;
Described drive link 5 one ends match with electrical apparatus release, and the other end matches with displaying block 3, and can swing;
Described spring 4 is in the bottom of displaying block 3, by chassis 2 supports that have breach;
The upper table surface P of described displaying block 3 has " short circuit " sign;
Described chassis 2 is connected with installing plate 1.
In conjunction with the accompanying drawings, further specify the utility model content.
The synoptic diagram of the short trouble display device of Fig. 1 armature structure
Fig. 2 display structure A-A cut-open view
The electrical apparatus release B-B cut-open view of Fig. 3 armature structure formula
Fig. 4 is the synoptic diagram of the short trouble display device of loop construction
Fig. 1, Fig. 2, Fig. 3 are the schematic diagrames of the short-circuit fault displaying device of armature structure.
With reference to Fig. 1, Fig. 2, Fig. 3, at an installing plate 1 with good insulating performance and mechanical strength chassis 2 is housed, its In the parts such as displaying block 3, spring 4 are arranged, pressing drive link 5 on the Q plane of displaying block 3, its other end and armature 8 are fixed on Together, armature 8 is being supported by axle sleeve 6.
When the instantaneous short circuit electric current flows through lead 7, the electromagnetic attraction of generation attracts armature 8, turns over certain angle, and drive link 5 is sliding The Q plane of lower displaying block 3 under the thrust of spring 4, promotes displaying block 3 and pops up, and exceeds the plane of installing plate 1, Block simultaneously drive link 5, it can not be resetted, electrical apparatus release is in trip status, and breaker can not close a floodgate. Treat operating personnel After the handling failure, press displaying block 3, under the effect of back-moving spring 9, drive link 5 and then armature 8 resets, and electrical apparatus release is extensive Multiple normal operating conditions, breaker can carry out normal operating.
Fig. 4 is the schematic diagram of the short-circuit fault displaying device of loop construction.
With reference to Fig. 4, the C unshakable in one's determination armature 8 of ining succession. When the instantaneous short circuit electric current flows through coil e, the electromagnetic attraction of its generation attracts iron Heart C moves upward, and the course of work was ditto described after all the other display unit reached.
The utility model advantage:
Short trouble and cause that fault type that various breakers turn-off has and clearly show brings convenience to the maintenance personal.
Embodiment 1
Be assembled into the short trouble display device of armature structure by Fig. 1.Through using, display effect is obvious, and is easy to maintenance.
The main display device of being made up of drive link 5, spring 4, displaying block 3 etc. is that loop construction matches with electrical apparatus release, and Fig. 4 is the part synoptic diagram of the short trouble display device of loop construction.Through using, display effect is obvious, and is easy to maintenance.
Claims (1)
