Content of the invention
The present invention, in order to make up the defect of prior art, provides one and can automatically detect transmission line of electricity rapidly and accurately The failure detection device for power transmission line of fault.
The present invention is achieved through the following technical solutions:
A kind of failure detection device for power transmission line, it is characterised in that:Including processor, display and failure detector, multiple Described failure detector is at scattering device along transmission line of electricity, and described failure detector includes that voltage sensor, electric current pass Sensor and communication unit, described voltage sensor is for detecting the voltage-to-ground of current location in this fault detect transmission line of electricity simultaneously Sending to described communication unit, described current sensor is for detecting the electric current of current location in transmission line of electricity and sending extremely described Communication unit, described communication unit is connected to described voltage sensor and described current sensor, the voltage for receiving Information and current information send to described processor by way of being wirelessly transferred.Processor, for according to from described communication list Information of voltage that unit receives and current information judge the fault message of each failure detector present position;Described display Device, is connected to described processor, the fault message event corresponding with this fault message receiving from described processor for display The information of barrier detection device.
This failure detection device for power transmission line, also includes alarm device, and described processor is additionally operable to, and is judging at least one Alarm signal is sent to described alarm device during individual fault message;Described alarm device is connected to described processor, for connecing Alarm is sent when receiving alarm signal.By this technical scheme, operation maintenance personnel can be facilitated to find fault message more quickly, from And process transmission line malfunction in time.
The invention has the beneficial effects as follows:This failure detection device for power transmission line, workable, can quick and precisely find defeated Line fault point, it is achieved that detection automatically, upload and the display of fault, can facilitate operation maintenance personnel to find fault in time, Improve the reliability of operation of power networks, be that safety, the economical operation of power circuit provides powerful guarantee.
Brief description
The present invention is further illustrated below in conjunction with the accompanying drawings.
The block diagram that accompanying drawing 1 is failure detection device for power transmission line of the present invention.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.As shown in Figure 1, this failure detection device for power transmission line, such as Fig. 1 Shown in, transmission line malfunction detecting system according to an embodiment of the invention, including processor, display and multiple fault detect Device, multiple described failure detectors are at scattering device along transmission line of electricity, wherein:Described failure detector includes voltage Sensor, current sensor and communication unit, described voltage sensor is used for detecting present bit in this fault detect transmission line of electricity The voltage-to-ground put transmission are to described communication unit, and described current sensor is for detecting the electricity of current location in transmission line of electricity Flow and send to described communication unit, described communication unit be connected to described voltage sensor and described current sensor, for Send the information of voltage receiving and current information to described processor by way of being wirelessly transferred;Described processor, uses In judging each failure detector present position according to the information of voltage receiving from described communication unit and current information Fault message, and will determine that result and this judged result corresponding failure detector information send to described display.Described Display, is connected to described processor, and the fault message receiving from described processor for display is corresponding with this fault message The information of failure detector.Also include alarm device, wherein:Described processor is additionally operable to, and is judging at least one event Alarm signal is sent to described alarm device during barrier information;Described alarm device is connected to described processor, for receiving Alarm is sent during alarm signal.By this technical scheme, operation maintenance personnel can be facilitated to find fault message more quickly, thus and When process transmission line malfunction.
In case of a fault, patrol officer can be helped quickly to search position of failure point, such as short circuit trouble point, ground connection event Barrier point, overload section, thunderbolt section, power failure section, insulation decline section etc., it is adaptable to distribution overhead line, distribution cable Circuit, the online trouble shoot of transmission line of electricity, it can be determined that the classification of circuit running status change, ground connection, short circuit, broken string, real When prosecution circuit running status, detection line short, ground connection, overload, broken string etc., and on line map, show faulty line And position send audible alarm, simultaneously by the position of fault and type notification operator on duty, it is to avoid the expansion further of accident.
