Description
The utility model relates to power high voltage contact optical fiber on-Line Monitor Device in a kind of power supply system.
At present, in power supply system, following way is mainly adopted in monitoring to high-voltage contact: the one, and adopt infrared telescope observation high-voltage contact whether to have unusually, the 2nd, whether the electrician personnel adopt the way of sealing with wax, melt with wax and judge the whether working properly of high-voltage contact.More than the shortcoming of two kinds of ways be to need artificial observation, the poor reliability, even the omission of breaking down of being interrupted.In a word, working condition that can not the real time on-line monitoring high-voltage contact.
The purpose of this utility model is the deficiency at existing high-voltage contact monitoring technology, provide a kind of can on-line monitoring, in time feed back the power high voltage contact optical fiber on-Line Monitor Device of high-voltage contact working condition.
For reaching above-mentioned purpose, the utility model power high voltage contact optical fiber on-Line Monitor Device comprises the high-voltage contact fibre-optical sensing device, photoelectric conversion module, environment reference signal generating means, voltage amplifier circuit, signal processing module, display screen and connect the output interface of computing machine, described power high voltage contact fibre-optical sensing device are by the heat-conduction component that closely contacts with the high voltage supply line contacts, firmly be installed in the moving grating of heat-conduction component, the quiet grating that suitable distance is arranged and be oppositely arranged with moving grating, relative fixed is installed in moving grating, the input optical fibre and the output optical fibre in the quiet grating outside, the light source that another termination of input optical fibre connects is formed.
Because the utility model power high voltage contact optical fiber on-Line Monitor Device, when the power high voltage contact temperature changes, heat-conduction component produces linear displacement, drive moving pattern displacement, make output intensity produce linear change, convert the variation of electric signal to through optical-electric module, after the electric signal processing module compares processing to online electric signal and reference signal, being transported to display screen shows, simultaneously, signal is delivered to computer controlling center by outlet line carry out respective handling, the deficiency that the utility model has overcome existing high-voltage contact monitoring technology has realized on-line monitoring, the purpose of feedback high-voltage contact working condition variation in time, can make the relevant personnel in time grasp situation, the utility model is measured the temperature rise of contact in real time, and can set normal according to standard, hidden danger early warning, and fault warning.Scent a hidden danger in advance, advanced processing and the automatic excision of fault are fast avoided causing big loss, are significant improvement to prior art.
Accompanying drawing 1 is the fibre-optical sensing device synoptic diagram of power high voltage contact optical fiber on-Line Monitor Device.
Accompanying drawing 2 is a power high voltage contact optical fiber on-Line Monitor Device electrical schematic diagram.
In Fig. 1, heat-conduction component 10 closely contacts with the high voltage supply line contacts, moving grating 13 is connected with heat-conduction component 10, quiet grating 11 has suitable distance with moving grating 13, and be oppositely arranged, input optical fibre 14 and output optical fibre 12 are installed in moving grating 13, quiet grating 11 outsides by stationary installation 16 relative fixed, and input optical fibre 14 terminations connect light source 6.
In Fig. 2, the light detection signal of fibre-optical sensing device 1 output and the reference arm light signal that transmits through reference optical fiber 15 enter the voltage signal that obtains behind the photoelectric conversion module 2, send into after signal handover module 7 is selected and send into signal processing module 4 again after voltage amplifier circuit 3 carries out processing and amplifying; Also send into processing module 4 simultaneously by the environment reference signal that environment reference signal generating means 8 sends.Signal processing module 4 carries out becoming digital signal after AD changes with the signal that obtains and carries out sending into display screen 5 by output port after computing, processing, the arrangement, show the sign of normal, early warning, warning outage by the requirement of power supply department high-voltage contact temperature, carry out uninterrupted in real time monitoring.Another road is undertaken utilizing outlet line after the level conversion by Asynchronous Serial Interface module 9, and the control center that sends into power supply department by corresponding data-interface uninterruptedly monitors and controls.A plurality of contact fibre-optical sensing devices can be set as required.Photoelectric conversion module adopts CA3140, the signal handover module adopts CD4051, and three voltage amplifier circuit modules all adopt LM324, and signal processing module adopts P87LPC767, environment reference signal generating means is made up of LM35 and U2D, and 232 and 485 interface modules adopt MAX232.Also available other circuit are realized above function.But realize all falling into protection domain of the present utility model to the high-voltage contact on-line monitoring and by what photoelectric switching circuit became that electric signal in time feeds back the high-voltage contact working condition as long as adopt power high voltage contact fibre-optical sensing device.
