Abstract
The utility model discloses an ice covering thickness testing device for a high-voltage transmission line, which is characterized by comprising a microprocessor, an alarm and a plurality of photoelectric sensors which are arranged on the two sides of a high-voltage transmission line to be tested. The photoelectric sensors are all connected with the microprocessor, the microprocessor is connected with the alarm, and two to eight photoelectric sensors are used. The utility model has a novel structure. With the novel structure, the utility model not only can detect the thickness of the ice covering on the high-voltage transmission line, but also has the alarm function.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of high voltage transmission line ice covering thickness pick-up unit.
Background technology
In grid, behind the big ice damages of economizing of the serious harm south that has experienced 08 year, icing is obvious to all to the harm of high voltage transmission line more, icing is too thick on the power transmission line, gently then causes power transmission line to be pressed down, and causes power breakdown, heavy then with the transmission of electricity an iron rake with three to six teeth can both break, cause bigger harm.Therefore, the detection of the ice covering thickness on the power transmission line is necessary, bigger support can be provided for the integral monitoring of power network.
The utility model content
The utility model wants the technical solution problem that a kind of high voltage transmission line ice covering thickness pick-up unit is provided, and this high voltage transmission line ice covering thickness pick-up unit is novel, not only can detect the ice covering thickness on the high voltage transmission line, also has warning function.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of high voltage transmission line ice covering thickness pick-up unit, it is characterized in that, comprise microprocessor, alarm and be arranged on a plurality of photoelectric sensors of high voltage transmission line both sides to be detected, described a plurality of photoelectric sensor all is connected with described microprocessor, and described microprocessor is connected with alarm.
Described photoelectric sensor is 2～8.
Principle of the present utility model is, when not having icing to exist, the signal that the transmitting terminal of photoelectric sensor sends can successfully be received termination and receive, the effective electric signal of photoelectric sensor (such as high level signal) output, and therefore microprocessor does not start warning.In case there is icing in power transmission line, and blocked the optical signal transmission path of photoelectric sensor when icing after, the receiving end of photoelectric sensor just can't receive the light signal that transmitting terminal sends, photoelectric sensor does not just have effective electric signal (such as low level signal) to output to microprocessor, and this moment, microprocessor can start warning.
The beneficial effects of the utility model have:
The utility model utilizes photoelectric sensor commonly used to detect ice covering thickness cleverly, and is novel.In addition, by a plurality of photoelectric sensors that are provided with side by side, can detect the general size of ice covering thickness, microprocessor can be according to the numerical value contrast of ice covering thickness value of setting and time detecting, start in good time and report to the police, the prompting staff in time handles, in order to avoid icing causes huge harm to electric system.Therefore, the utlity model has bigger social effect and economic implications.
Description of drawings
Fig. 1 is that the utility model embodiment 1 detects the ice covering thickness principle schematic.
Label declaration: 1-photoelectric sensor transmitter, 2-power transmission line, 3-icing, 4-photoelectric sensor receiver.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
A kind of high voltage transmission line ice covering thickness pick-up unit, comprise microprocessor, alarm and be arranged on 4 photoelectric sensors of high voltage transmission line both sides to be detected, described 4 photoelectric sensors all are connected with described microprocessor, and described microprocessor is connected with alarm.
As shown in Figure 1,4 photoelectric sensors (A among Fig. 1, B, C, D) are arranged on the both sides of power transmission line, equidistant arrangement setting as shown in Figure 1.A photoelectric sensor all comprises 1 photoelectric sensor transmitter 1 and photoelectric sensor receiver 4, supposes that photoelectric sensor exports high level signal, output low level signal when light path is blocked when light path does not stop.Therefore, contrast Fig. 1, when not having icing on the power transmission line, A, B, four photoelectric sensors of C, D are all exported high level signal to microprocessor, when the icing on the power transmission line has as shown in Figure 1 thickness, because the light path of A and B photoelectric sensor is blocked, therefore the level of A and B photoelectric sensor output is low level, the light path of C and D photoelectric sensor is not blocked, and therefore, the output high level is to microprocessor.In this way, microprocessor can detect the state of each photoelectric sensor in real time, also just knows the situation of current ice covering thickness, when icing reaches certain thickness (such as the equal output low level signal of A and B photoelectric sensor time), just starts and reports to the police.
