Abstract
The utility model relates to a thunderstroke display device for high voltage transmission and distribution lines, comprising a display body and an upper cap matched with the boy, and fixed legs are arranged at the external part. The inner periphery of the body is provided with a coil, the central part of the body is provided with an air expanded cavity corresponding part of the upper cap, a fuse point and expanding agent are arranged in the cavity, color bands are arranged at both sides of the expanded cavity and are connected via a top and a bottom connecting legs. The utility model solves the problems of hard searching, finding, etc. of damaged line insulator in high voltage transmission and distribution lines in the prior art caused by thunderstroke.
Description
The utility model belongs to the display unit of lightning protection after being struck by lightning of iron tower or other buildings of high pressure electric line.
Existing way is: very time-consuming, take a lot of work when the iron tower of high pressure electric line is struck by lightning and when causing line insulator to damage, is gone to search in tens iron towers in tens of kilometers by the people fully, can not in time pinpoint the problems, so also be prone to danger.Also can't know the strength range of lightning current.
The purpose of this utility model provides a kind of high pressure transmission line thunderstroke display device, and after high pressure transmission ﹠ distribution line was struck by lightning, he can promptly and accurately show.
This purpose realizes with following technical proposal: this high pressure transmission line thunderstroke display device, he has the body of a display and the loam cake that matches with body, outside at them is provided with fixed leg, wherein week be provided with induction coil in the body, the corresponding position of its centre and loam cake constitutes expansion chamber, and the gas swelling agent is arranged in the chamber, and the fire point of leading in coil and the expansion chamber joins, the both sides of expansion chamber are provided with sign band, and they are connected on the set joint pin of body and loam cake.
This thunderstroke display device can promptly and accurately show when the high pressure transmission line is struck by lightning, so the target that the line maintenance personnel can in time pinpoint the problems in time solves, avoids other dangerous generation; Can determine the magnitude range of lightning current in addition by its expression.
Following accompanying drawing has provided embodiment of the present utility model:
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
As shown in Figure 1, 2: this high pressure transmission line thunderstroke display device is used on the high pressure transmission line iron tower, it has monitor body 1, the loam cake 2 that matches with body, see from external form and to resemble an oblate article-container, side at box is equipped with fixed leg 3, this fixed leg is fixed on the high voltage line iron tower, as shown in Figure 2: all devices of body 1 inner bottom part have induction coil 4, are provided with a hollow cylinder at the body middle part.Loam cake cooperates for pegging graft with body.Middle part in loam cake also is provided with an open tubular column, he and the corresponding cooperation of hollow cylinder at body middle part.Make it constitute an expansion chamber 5, swelling agent 7 is housed in the expansion chamber.The left and right sides of expansion chamber (be body bottom and last tops) is equipped with fixed leg 8, identifies to be with 6 to be connected up and down on the fixed leg 8 respectively by holding piece 9.
After iron tower is struck by lightning, flow through lightning current on the iron tower, when the intensity of lightning current reaches the degree that the dielectric strength that makes insulator is damaged, coil produces induced current, and pass to by lead and to lead duration and degree of heating in the expansion chamber, this thunderstroke display device action, the gas swelling agent releases energy and arranges the display loam cake, emit the sign band simultaneously, demonstrate operate condition.For the line maintenance personnel provide tangible target.
