Abstract
The invention discloses a system for intelligently measuring the temperatures of critical components in a power grid. The system comprises a photoelectric detector array and a fiber Bragg grating module. The photoelectric detector array detects, returns and outputs the power of a laser device, the power is amplified through an amplifier to be then input into an industrial personal computer through a data collecting card, the industrial personal computer outputs a control signal to control the laser device through a light source driving unit, the fiber Bragg grating module is arranged on the emitting light path of the laser device, collects temperature information through laser signals and is connected with photoelectric detectors through an optical fiber beam splitter, and a display module is connected to the industrial personal computer. According to the system, remote real-time measurement on the temperatures of various monitoring points in the power grid can be achieved, and the measurement results are accurate.
Description
?
Technical field
The present invention relates to intelligent grid technical field, particularly the system of critical component temperature in a kind of intelligent measure electrical network.
Background technology
Electrical network is in electric system, the general designation of the facilities and equipment of contact generating and electricity consumption.Belong to the intermediate link of carrying and distributing electric energy, it mainly forms by connecting power transmission sequence into the net, electric substation, distribution substation and distribution line.The safety of electrical network is most important, and fire is the biggest factor that affects power grid security, causes in the reason of electrical network fire, and electrical network parts are overheated is major reason.Therefore critical component in electrical network is carried out to temperature monitoring in real time very necessary.
Existing monitoring easy thermometer or the temperature sensors of adopting, by artificial observation reading, method equipment is all very backward, and reading can produce certain error, also has very large hysteresis quality simultaneously more.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide the system of critical component temperature in a kind of intelligent measure electrical network, there is feature easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
The system of critical component temperature in a kind of intelligent measure electrical network, comprise photodetector array and fiber grating module, photodetector array is surveyed the power of return laser light device, output inputs to industrial computer by data collecting card again after amplifier amplifies, industrial computer output control signal is by light source driving units control laser instrument, in the transmitting light path of laser instrument, fiber grating module is set, fiber grating module is by laser signal collecting temperature information, fiber grating module connects photodetector by fiber optic splitter, and industrial computer is connected to display module.
The present invention compared with prior art, can realize the long-range real-time measurement to each monitoring point temperature in electrical network, and measurement result is accurate.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is carried out to more detailed explanation.
As shown in the figure, the present invention is the system of critical component temperature in a kind of intelligent measure electrical network, comprise photodetector array and fiber grating module, photodetector array is surveyed the power of return laser light device, output inputs to industrial computer by data collecting card again after amplifier amplifies, industrial computer output control signal is by light source driving units control laser instrument, in the transmitting light path of laser instrument, fiber grating module is set, fiber grating module is by laser signal collecting temperature information, fiber grating module connects photodetector by fiber optic splitter, industrial computer is connected to display module.
Photodetector array is surveyed the power of return laser light device, be output as current signal, the signal of output first converts voltage signal to, after amplifying, amplifier inputs to industrial computer by data collecting card again, industrial computer is stored the data that gather, relatively wait after operation, output control signal control light source driver module drives laser works, make laser instrument send periodic exploring laser light, and fiber grating module can be obtained temperature information to the modulation of fiber optic wavelength by ambient temperature, industrial computer is crossed display module by the information exchange obtaining and is shown, and can be sent to remote server by wireless communication module.
