Description
Technical field
The utility model relates to feeder cable transmission context of detection, more particularly relates to a kind of high voltage power transmission cable insulation pick-up unit.
Background technology
Electric power is the topmost productive life energy of our times, and along with the progressively quickening of The development in society and economy and modernization construction paces, commercial production and people's lives are maked rapid progress, and are also more and more to the demand of electric power, how to ensure that the safe transport of electric power is directly connected to national economy.Electric wire and cable is the most widely used equipment and material in the power transmission system, and in the equipment and material that all kinds of electrical hazards relate to, and relevant with cable and wire has accounted for almost 50%, and wherein major part is again because due to the insulation damages.The high voltage power transmission cable is just as the artery of electrical network, and its insulating property concern safety and the high efficiency that electric power is carried, and are very necessary so develop a kind of high voltage power transmission cable insulation pick-up unit.
The utility model content
Technical problem to be solved in the utility model is, a kind of high voltage power transmission cable insulation pick-up unit is provided, can give transponder pulse signal in the cable of connecting, by receiving and analyze the damage in insulation situation that the reflected impulse signal is analyzed cable, thereby in time damaged cable is safeguarded, avoided causing damage to electric power conveying and personal security.It is simple to operation, and adaptability is strong, can reflect fast that the cable insulation situation changes.To timely detection streamer insulating property, prevention further loss plays an important role.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of high voltage power transmission cable insulation pick-up unit comprises high-voltage pulse power source (1), input/output module (5), single chip control module (2), pulsed signal device (4), A/D signal converter (3) etc.Wherein input/output module (5) comprises the by-pass cock (6) of the whole device operation of control and demonstration result's display screen (7).High-voltage pulse power source (1) connects single chip control module (2) as pulse signal generator by lead, single chip control module (2) is connected with A/D signal converter (3) by lead, A/D signal converter (3) is responsible for the digital signal that receives is converted to simulating signal, and A/D signal converter (3) is connected with pulsed signal device (4) by lead, the result that input/output module (5) is responsible for the operation of the whole device of control shows, and input/output module (5) is connected with single chip control module (2) by lead.After whole device energising starts, regulate the by-pass cock (6) on the input/output module (5), single chip control module (2) transmits instruction for high-voltage pulse power source (1), high-voltage pulse power source (1) sends pulse signal just for the feeder cable that is connected, pulse signal is propagated in feeder cable, when propagating into damage in insulation place on the cable, pulse signal can reflect a sudden change pulse signal, pulsed signal device (4) passes to A/D signal converter (3) after receiving this jump signal, A/D signal converter (3) converts the digital signal that receives to simulating signal and passes to single chip control module (2) again, single chip control module (2) is calculated by default program, at last this simulating signal is delivered to input/output module (5), and pulse signal waveform and result of calculation are shown at display screen (7).
The beneficial effects of the utility model are: the utility model utilizes pulse signal can reflect the sudden change pulse principle of returning running into breakpoint or breaking point, by transponder pulse signal in toward high-voltage pulse power source toward feeder cable and receive the reflected impulse signal, again the jump signal that receives is analyzed, thus the position that draws the feeder cable damage in insulation.The mistiming of utilizing pulse signal to propagate is like this obtained concrete positional information, and whole device is simple to operate, wide adaptability, and the economy height, safe and efficient, extraordinary popularizing application prospect is arranged.
