Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in more detail.
Embodiment 1
A kind of band punctures the insulator of display device, includes insulator body and inductor.Described insulator body comprises insulating part 1, steel foot 2, chapeau de fer 3, flange 4 and binding post 9.Described inductor comprises iron core 5, induction coil 6,555 integrated signal processes circuit 7, signal display circuit.
Described band punctures the insulator of display device, such as Fig. 1,2,3, by on the basis of the insulator of former common production, add installation inductor, iron core 5 is socketed and is fixed on insulating part 1 inside with the steel foot 2 upper end mucilage binding being arranged in insulator body after being wound around upper induction coil 6, forms electromagnetic field inducing signal and also exports to inductor signal processing circuit.Described inductor signal processing circuit is that the fault-signal that inductor detection receives is compared and enlarged process, exports finally by display circuit 8.
The inductor signal processing circuit stated uses 555 integrated amplifier compositions, and input amplifier connects two lead-in wires of induction coil, and the outfan of amplifying circuit connects luminous body, and whole device glue is fixed on below insulator.
Described inductor signal display circuit uses the LED light emitting diode 8 of super low consumption power.It is connected with the signal output part of 555 integrated amplifier compositions, and it is peripheral to be fixed on insulating part, it is achieved signal display effect during insulator breakdown, it is simple to equipment operation maintenance personnel finds in time and fixes a breakdown.
When the insulator of this structure is properly functioning, when i.e. insulator is the most breakdown, insulator is connected with electrical equipment or with steel foot 2 lower end of another insulator by binding post 9, now the binding post 9 of insulator is insulated by insulating part 1 completely with steel foot 2 upper end of insulator, inductor does not exist electric field signal, now, the induction coil 6 inlayed and be fixed in the iron core 5 of insulating part 1 internal steel foot 2 upper end does not has electric field induction signal, 555 integrated packages 2 being connected are exported with induction coil 6 signal, 6 feet are in high level, 555 integrated package 3 foot output low levels, LED display circuit lamp does not works, display insulator and other insulator equipment normal operation being attached thereto.
Insulator abnormal running when this structure, during the most breakdown operation, the binding post 9 of insulator is discharged by insulator between chapeau de fer 3 and ferrum foot 2, the electric arc produced makes insulator destroy, formed between the binding post 9 of insulator and ferrum foot 2 and be conductively connected, now, the induction coil 6 being fixed in the iron core 5 of insulating part 1 internal steel foot 2 upper end induces electric field signal, 555 integrated packages 2 being connected are exported with induction coil 6 signal, 6 feet are in low level, 555 integrated package 3 foot output high level, LED display circuit lamp is bright, display insulator and other insulator equipment being attached thereto are breakdown, wired earth is the most easily caused even to be short-circuited fault.In the middle of actual motion, a little insulator of also can connecting again between this device with grounding body, when there is the insulator breakdown display signal of this device, as long as operation maintenance personnel is replaced breakdown insulator in time, so that it may be prevented effectively from the generation of above fault.
