The collection of video, temperature, voice signal is carried out, and earthward main control computer provides intuitively cable fortune to have laptop computer to pass through network
Market condition, implements fault location when cable breaks down, because the parameter for detecting is more, so complex structure, operates also not side
Just；For another example Chinese patent 201410059038.6, disclose a kind of " cable local discharge detection device ", including concussion wave voltage
Generation module, signal acquisition module, analysis and Control module, equally exist complex structure, the shortcoming of inconvenient operation.
The generally short trouble it is well known that transformer station's inner high voltage cable breaks down, and electric arc is produced, and along with big
The luminous energy and heat energy of amount.Because cable duct is covered by cover plate, its interior visible ray is few, therefore the visible ray that cable fault is produced is
The detection that failure occurs provides preferable criterion.
At present, there is not yet judging the report of the equipment of cable fault position by the visible ray of cable fault generation.
The content of the invention
Cable fault position is judged by visible ray that cable fault is produced it is an object of the invention to provide a kind of and
And simple structure, the cable duct of substation cable discharge optically focused easily implementing, be exclusively used in cable duct of substation Cable fault examination
Alarm detector.
In order to reach object above, the technical solution adopted in the present invention is：The cable duct of substation cable discharge optically focused

Connect；The center of circle of collector lens is with the center of circle of photoelectric conversion module on an axis.
The present invention is also implemented by following measure：The upper end of described cylinder is provided with strip magnetic patch, in strip magnetic patch
Slide opening in penetrate insulation leading line, insulation leading line suspends and is fixed on the middle part upside of cable duct, from cable channel cover plate base plate
Face 4cm；The slip of strip magnetic patch is to attract strip magnetic patch using electromagnetic wand on the upside of cable channel cover plate by patrol officer
And pull realization.
Described photoelectric conversion module, including OPT101 chips, the pin 1 of OPT101 chips connect 12V dc sources,
The pin 2 of OPT101 chips and indirect the resistance R1 and electric capacity C4 in parallel of pin 5,6,7, for adjusting output voltage signal
Size；The pin 1 of OPT101 chips, pin 4 and pin 8 are grounded through electric capacity C1, C3, C2 respectively；The pin 5 of OPT101 chips is
Output voltage high level signal Vout, accesses the Vin pins of voice guard.
Described voice guard, including triode T1, relay K1, buzzer S, the Vin pins of voice guard lead to
The base stage that resistance R2 accesses triode T1 is crossed, the emitter stage of triode T1 is grounded by resistance R3；The grid of triode T1 passes through
Relay K1 is grounded, and connects one end of buzzer S simultaneously；Another termination 12V dc sources of buzzer S；Triode T1 is triggered
Conducting, buzzer S, power Vcc form conducting loop, and buzzer S shouts a shout, after pressing relay K1, triode T1 is short
Road, signal return.
The beneficial effects of the present invention are：The cable duct of substation cable discharge optically focused alarm detector, due to using
Arclight optically focused during cable short circuit is converted to the principle of alarm signal, at the same employ isolation cable channel cover plate, by magnetic
Suction pull detection means along cable move, so simple structure, easily implement, can soon check quickly and patrol cable location of short circuit,
Cable channel cover plate is opened in accurate position, so as to significantly reduce labor intensity, is raised labour efficiency, power transformation can be exclusively used in
Stand the detection of cable duct cable fault.
