Abstract
The invention provides a monitoring device in the electric field, in particular to a lightning stroke expansion displayer of a high-voltage power transmission line. A rod tower is fixedly pulled with a transmission line by an electrical insulator and a suspension clamp; the two sides of the rod tower are respectively fixedly provided with an expansion displayer which has the shape of plate and has a colorful cloth by a pressure spring and a hot melt needle pin; and when the plate-shaped expansion displayer is opened, a colorful cloth display fan face is exposed. After being installed on the power transmission line, the lightning stroke expansion displayer can be used for directly observing and judging the damage condition of the line according to whether being opened,, thereby preventing from the work due to artificially inspecting and researching lightning strike points on the spot. The lightning stroke expansion displayer is applicable to being installed on the power transmission line to use.
Description
Technical field
The present invention is to provide the supervising device of electric field, specifically lightning stroke expansion displayer of high-voltage power transmission line.
Background technology
After the 66-220KV transmission line is struck by lightning in the past, according to protection action situation, organize corresponding manpower that delivery circuit is maked an inspection tour, because damage to crops caused by thunder mostly occurred in summer, the road is muddy through a rainfall for thunder, the weather sweltering heat brings very big difficulty for tour work.Being located in the shaft tower of locating in high mountain, forest land, cropland, stream etc. all needs the tour personnel to check by the base, sometimes lightning strike spot is not obvious or be subjected to the influence of weather be difficult to find the fault point, also need to intersect again tour, in case of necessity by basic rod-rising tower inspection, difficulty increases, the dangerous increase, both just like this, also can not check the fault point sometimes, hidden danger can not in time be excluded, overlap and well or by force send the equipment of success also will move in spite of illness, power supply reliability is difficult to guarantee.
Summary of the invention
In order to realize in time finding after transmission line is struck by lightning, the invention provides lightning stroke expansion displayer of high-voltage power transmission line.This expansion displayer makes expansion displayer opened by the elastic force of gravity and stage clip and presents covering of the fan, thereby determine whether to be struck by lightning and corrupted by thunderbolt heat production fusing hot melt pin, solves the technical problem of thunderbolt back Direct observation lightning strike spot with this.
The scheme that technical solution problem of the present invention is adopted is: draw intrinsic power transmission line by insulator and suspension clamp on shaft tower, be fixed with tabular by stage clip and hot melt needle pin respectively in the shaft tower both sides and have the expansion displayer of colored cloth, when tabular expansion displayer open mode, manifest colored cloth and show covering of the fan.
Good effect is: after the present invention is installed on the transmission line, can whether opens Direct observation and judge the circuit damage situations by expansion displayer, the work of searching lightning strike spot with the scene of avoiding manual patrol.Suit on transmission line, to install and use.
Description of drawings
Fig. 1 is expansion displayer closure state figure of the present invention
Fig. 2 is expansion displayer open mode figure of the present invention
Among the figure, 1. insulator, 2. suspension clamp, 3. power transmission line, 4. expansion displayer, 4.1. shows covering of the fan, 5. stage clip, 6. hot melt needle pin.
Embodiment
According to shown in Figure 1, on shaft tower, draw intrinsic power transmission line 3 by insulator 1 and suspension clamp 2, be fixed with tabular by stage clip 5 and hot melt needle pin 6 respectively in the shaft tower both sides and have the expansion displayer 4 of colored cloth, when tabular expansion displayer open mode, manifest colored cloth and show covering of the fan 4.1.
Under the normal condition, be subjected to drawing of hot melt needle pin solid, tabular expansion displayer is the sealing state, and colored cloth is sheltered onboard.
When part of path is struck by lightning, produce heat effect between thunder and lightning and the circuit, make the fusing of hot melt needle pin, tabular expansion displayer loses the solid effect of drawing of hot melt needle pin, is subjected to the gravity sag effect of the elastic reaction and the display board self of stage clip, and its plate is perpendicular to the ground, the colored cloth that is fixedly connected with it is the covering of the fan state and opens and show, promptly can be observed the state of the expansion displayer of having opened by range estimation or telescope, thereby judge whether track section has suffered thunderbolt, and then repair.
But colored cloth fiber cloth, nonwoven fabrics or Polypropylence Sheet.
Claims (1)
1. lightning stroke expansion displayer of high-voltage power transmission line, on shaft tower, draw intrinsic power transmission line (3) by insulator (1) and suspension clamp (2), it is characterized in that: be fixed with tabular by stage clip (5) and hot melt needle pin (6) respectively in the shaft tower both sides and have the expansion displayer (4) of colored cloth, when tabular expansion displayer open mode, manifest colored cloth and show covering of the fan (4.1);
Under the normal condition, be subjected to drawing of hot melt needle pin solid, tabular expansion displayer is the sealing state, and colored cloth is sheltered onboard;
When part of path is struck by lightning, produce heat effect between thunder and lightning and the circuit, make the fusing of hot melt needle pin, tabular expansion displayer loses the solid effect of drawing of hot melt needle pin, is subjected to the gravity sag effect of the elastic reaction and the display board self of stage clip, and its plate is perpendicular to the ground, the colored cloth that is fixedly connected with it is the covering of the fan state and opens and show, promptly can be observed the state of the expansion displayer of having opened by range estimation or telescope, thereby judge whether track section has suffered thunderbolt, and then repair.
