Specific embodiment
As shown in Fig. 1, Fig. 2, a kind of fault detector for electric distribution network is made up of control end and mobile terminal；
The control end is by rectification unit 1, lithium battery 2, display screen 3, memory module 4, single-chip microcomputer 5, signal generating module
6th, current transformer 7, wireless communication module 8, alarm module 9 are constituted.
The rectification unit 1 connects lithium battery 2, the connection of lithium battery 2 display screen 3, single-chip microcomputer 5, wireless communication module 8 and report
Alert module 9；The connection of the single-chip microcomputer 4 display screen 3, memory module 4, signal generating module 6, current transformer 7, radio communication mold
Block 8 and alarm module 9.
The mobile terminal by rectification circuit 11, lithium battery 12, display screen 13, one-chip computer module 14, wireless communication module 15,
Current transformer 16, power transformer 17, GPS module 18, solar panels 19 are constituted.
The rectification circuit 11 connects lithium battery 12, the connection of the lithium battery 12 display screen 13, one-chip computer module 14, wireless
Communication module 15, GPS module 18 and solar panels 19；The one-chip computer module 14 connection display screen 13, wireless communication module 15,
Current transformer 16, power transformer 17 and GPS module 18.
When using, under faulty circuit power down mode, control end is by the connecting fault circuit of signal generating module 6 and order
Characteristic signal is sent to faulty circuit, current transformer 7 measures the electric current and magnitude of voltage of faulty circuit, and testing result is shown
On display screen 3, according to following 2 failure judgement situations：
If the firstth, distribution line be short-circuited failure when, control end to the loop between trouble point can flow through very big
Electric current, the present apparatus uses maximum current as basis for estimation, if detecting what line electricity flow valuve sent more than signal generating module 6
Current value is then judged as short trouble, and alarm module 9 is alarmed, then using the node inspection one by one of mobile terminal current transformer 16
Faulty line is surveyed, and testing result is included on display screen 13, the maximum place of current value is trouble point, then by nothing
Trouble point GPS position information is sent to control end and stored to memory module 4 by line communication module 15；
The secondth, if earth fault occurs in distribution line, according to Kirchhoff's law, characteristic signal is a little by ground connection
Point constitutes loop, and the signal sending point of control end is used as starting point, then with regard to energy on the path from starting point to earth fault
The characteristic signal equivalent with the signal for sending is measured, rather than faulty section can only measure very small characteristic signal（By on circuit
Caused by transformer and PT influences）, examined along faulty line using the current transformer 16 and voltage transformer 17 of mobile terminal
Survey, illustrate that trouble point, in test point downstream, illustrates trouble point if characteristic signal is not detected if characteristic signal is detected
In test point upstream, trouble point is eventually found around this principle, then by wireless communication module 15 by trouble point GPS location
Information sends to control end and stores to memory module 4.
The above, implementation method is only that the preferred embodiment of the present invention is described, not to of the invention
Scope is defined, and on the premise of the spirit for not departing from the technology of the present invention, this area engineers and technicians are to skill of the invention
Various modifications and improvement that art scheme is made, all should fall into the protection domain of claims of the present invention determination.
