Specific embodiment
As shown in Figure 1, 2, the powered warning failure body case of annunciator of overhead transmission line is by component housing 4, clip 2, the and of bracket 1
The combination of alarm mechanism 5 is constituted, and clip 2 is located at the top of component housing 4, for clamping cable, alarm is fixed on built on stilts
On circuit, bracket 1 is the umbrella-shaped structure that Open Side Down, and its upper surface is fixed with solar panel 3, therefore solar panel
3, to incline fixation, can preferably absorb solar energy, improve generating efficiency, and solar charging panel is the electricity in component housing 4
Pond is charged, and solar charging panel is preferably composed in series by 4 pieces of 1.5V solar panels, and maximum charge power is up to 0.5W/H, battery
The lithium electricity of use, because the electronic component power consumption of alarm is low, and the arrangement of solar panel 3 is rationally, and it can
The self-sufficient of alarm electricity consumption is realized by solar panel 3, it is ensured that power consumption, it is not necessary to which external power supply changes battery.
Alarm is transformer induced to current field by built-in current, the current transformer when high-tension line normally runs
Sense can collect cable duty parameter, and current transformer sense outputs signal to controller, controller conveying alarm signal to report
Alarm device, is worked by driving warning device, so as to realize that real time on-line monitoring is pointed out.
Warning device includes light source 6 and alarm mechanism 5, the preferred LED of light source 6, and power consumption is low and long service life, and light source 6 sets
There is multiple, be uniformly fixed on the lower section of bracket 1, it is general to set 3-6, reliable luminosity had so both been can guarantee that, can also allow work
Making personnel can see the flicker alarm of light source 6 in all angles, it is to avoid by the interference (gear of centrally located component housing 4
Firmly light), the lower section inwall of umbrella bracket 1 can set reflectorized material coating in addition, coordinate the structure of the depression of bracket 1, can
Ensure that the direction of illumination of alarm light is downward, it is to avoid the waste of light intensity, umbrella bracket 1 can also protect light source 6 to be invaded by rainwater
Erosion, improves the use reliability and use quality of product.
Component housing 4 uses cylindrical structural, and the motor of battery, current transformer, controller and alarm mechanism 5 is solid
It is scheduled in component housing 4, battery is current transformer, controller, light source 6, motor are powered.
The lower section of component housing 4 is provided with alarm mechanism 5, and alarm mechanism 5 is adopted as cylindrical structural, size and component shell
Almost, alarm mechanism 5 includes cylindrical shroud, the circular rotating cylinder being fixed in shield and drives the motor of rotation body 4,
Controller output drive signal is to motor such that it is able to control rotating cylinder to be rotated in shield, and the first-class angle of shield is interval with
Printing opacity and lighttight region, it is general total to set 4,6 or 8, it is necessary to using even numbers number, so as to just can guarantee that printing opacity and not
Transmission region interval setting, for example, set 6, then printing opacity and light tight region account for 60 degree of regions of shield, and interval setting,
As shown in Figure 3.
The first-class angle of cylinder be interval with alarm fill color and non-alarm fill color region, alarm fill color can use
The eye-catching color such as red, yellow, non-alarm fill color is then using white, silver color, light gray etc. and the light tight area's color phase of shield
Near or identical color, alarm fill color and non-alarm fill color region typically add up to setting 4,6 or 8, it is necessary to using even numbers
Number, so as to just can guarantee that alarm fill color and non-alarm fill color region interval setting, for example, sets 6, then alarm filling
Color and non-alarm fill color region account for 60 degree of regions of shield, and interval setting.
The angle of the interval region on shield is identical with the angle of interval region on cylinder, that is, alarm fill color and non-alarm
The total quantity in the region of fill color is identical with total quantity of printing opacity and light tight region, and such three-way motor revolving drum can
Alarm fill color and non-alarm fill color region is set to reveal as needed, because light source 6 is generally white or yellowish, daytime
Light is difficult to strongly, is changed colour by making alarm bottom, cable operating mode can be easily identified, while can also coordinate
Light source 6 is alarmed cable difference operating mode.
The top of component housing 4 is provided with the clip 2 for clamping cable, and clip 2 includes being fixed on the top of component housing 4
Two pillars, the rotating shaft being arranged on pillar, the torsion spring of the intermediate plate being fixed in rotating shaft and connection rotating shaft and pillar, two
The end of individual intermediate plate is in contact, and pillar and intermediate plate are metal material, then the induction end of D.C mutual-inductor can be constituted, in order to improve
The reliability of clamping, V-shaped line groove is provided between the top of component housing 4 and intermediate plate, and wire casing upper surface is provided with anti-slip veins.
Control method based on the powered warning failure alarm of above-mentioned overhead transmission line：
Current transformer Real-time Collection cable duty parameter is simultaneously delivered to controller；
If during the powered normal operation of cable, the low frequency flicker of light source 6, and alarm mechanism 5 non-alarm fill color rotate to
Shield transmission region；
If cable tie electrical anomaly runs, the high frequency flicker of light source 6, and the alarm fill color of alarm mechanism 5 rotated to shield
Cover transmission region.
Wherein cable tie electrical anomaly operates to It>=180A or △ I >=0.5I0Or I=0 or 0.02s≤△ T≤3s, wherein
ItIt is Sudden Changing Rate current start value, △ I are current changing rate, I0It is line current before short circuit, I is electric current, △ T after line fault
It is the current break time.
So, when circuit is short-circuited or during earth fault, the alarm fill color of product alarm mechanism 5 is revealed,
And with LED high frequency flicker alarm indication, average 0.5 time/second；By the alarm indication of fault detector, especially at night
Tour personnel just can accurately judge rapidly fault section, branch and trouble point at a distance.Usually normal flashing light can be
When thering is circuit to joint use or under the alert status on live wire road, preventing fault rod climbing is played, protects the life security of operating personnel,
LED intermittence flash caution above powered attention device, average 3 seconds/time；Track walker can be according to the LED of electrification display
Lamp judges the situation of current line, is more convenient for the night routing inspection of a line line maintenance personnel to work.The installation of product makes
The simpler clearing of work is patrolled and examined on night overhead transmission line, manual operation operation is simplified, while for track walker provides
Safe warning function, the malfunction elimination to distribution line provides reliable safe practice guarantee.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented and do not receive aforesaid way
Limitation, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing
Enter and design of the invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
