Abstract
The invention discloses a portable line fault indicating device comprising a power supply, a detection pole plate, a central control unit, and an alarming prompting unit. The detection pole plate is the plate electrode capable of detecting the space electric field around the cable, and is connected with the central control unit provided with the alarming prompting unit. The central control unit is used to receive the space electric field information around the cable detected by the detection pole plate. When the received space electric field intensity reaches the threshold value, the cable is determined to be in the power-on state; when the received space electric field intensity is lower than the threshold value, the cable is determined to be in the power-off state, and the connected alarming prompting unit can be used for the acousto-optic alarming. The portable line fault indicating device is advantageous in that the structural composition is reasonable, and the use is convenient and reliable; after the occurrence of the fault, the fault section can be found out and determined quickly, and the fault point can be found out at the same time, and therefore the power supply reliability can be greatly improved, and the user satisfaction can be improved.
Description
Technical field
What the present invention relates to is a kind of portable circuit accident indicator, belongs to high-tension cable indicating fault technical field.
Background technology
Once high voltage cable breaks down, power failure can be difficult to search. First make troubles to people's life, disturb the normal production and operation of enterprise; Secondly cause greater loss to electric company. Can be solved in time for after breaking down at high-tension line, be improved the stable of power supply, so be necessary to develop a kind of portable circuit accident indicator.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of structure composition rationally, easy to use and reliable, can be after line failure, find out rapidly and definite fault section, find out trouble point simultaneously, can greatly improve the portable circuit accident indicator of power supply reliability, raising user satisfaction.
The object of the invention is to complete by following technical solution, a kind of pocket line fault indicating device, it comprises power supply, survey pole plate, central control unit and warning reminding unit composition, described detection pole plate is one can survey the plate electrode of cable surrounding space electric field, this detection pole plate line is in the central control unit with warning reminding unit, and receive and survey the cable surrounding space electric field information that pole plate detects by described central control unit, and in the time that the space electric field intensity receiving reaches threshold value, judge that this cable is as "on" position, if space electric field intensity is during lower than threshold value, think that cable is non-power status, and reported to the police by acousto-optic by the warning reminding unit being connected.
The present invention is mainly used in the path of indication fault electric current, and after line failure, line walking office worker can be by alarm indication of the present invention, finds out rapidly and definite fault section, finds out trouble point simultaneously; It has structure composition rationally, easy to use and reliable, can be after line failure, find out rapidly and definite fault section, and find out trouble point simultaneously, can greatly improve power supply reliability, improve the features such as user's satisfaction.
Brief description of the drawings
Fig. 1 is structure composition schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, a kind of pocket line fault indicating device of the present invention, it comprises power supply, survey pole plate 1, central control unit 2 and warning reminding unit 3 form, described detection pole plate 1 is one can survey the plate electrode of cable 4 surrounding space electric fields, this detection pole plate 1 line is in the central control unit 2 with warning reminding unit 3, and receive and survey the cable 4 surrounding space electric field informations that pole plate 1 detects by described central control unit 2, and in the time that the space electric field intensity receiving reaches threshold value, judge that this cable is as "on" position, if space electric field intensity is during lower than threshold value, think that cable is non-power status, and reported to the police by acousto-optic by the warning reminding unit being connected.
Embodiment: as Fig. 1, surveying pole plate is 1 one plate electrodes, system is surveyed cable 4 space electric field around by plate electrode, survey pole plate 1 induced signal is sent to control module 2, control module 2 converts data signal to after the small-signal of obtaining is amplified to shaping, by the extraction to data signal, if space electric field intensity reaches threshold value, think that this cable is "on" position, if space electric field is lower than thresholding, think that cable is non-power status, current state is confirmed current state by acousto-optic warning unit 3 to staff the most at last.
Claims (1)
1. a pocket line fault indicating device, it comprises power supply, survey pole plate, central control unit and warning reminding unit composition, it is characterized in that described detection pole plate is one can survey the plate electrode of cable surrounding space electric field, this detection pole plate line is in the central control unit with warning reminding unit, and receive and survey the cable surrounding space electric field information that pole plate detects by described central control unit, and in the time that the space electric field intensity receiving reaches threshold value, judge that this cable is as "on" position, if space electric field intensity is during lower than threshold value, think that cable is non-power status, and reported to the police by acousto-optic by the warning reminding unit being connected.
