Abstract
Provided is an electric power temperature-control system, comprising a fiber grating temperature sensor arranged inside a high voltage switch cabinet, wherein the fiber grating temperature sensor sends the collected temperature signals to an optical cable terminal box via an optical cable; the optical cable terminal box is connected to an fiber grating demodulation instrument via the optical cable; the fiber grating demodulation instrument sends the temperature signals into a PLC; and the PLC compares the received temperature signals to the set value and eventually outputs the control signals to a fan motor. The electric power temperature-control system utilizes a fiber grating temperature sensor to collect the temperature value inside the high voltage switch cabinet and is provided with the control and cooling execution functions. When the temperature inside the high voltage switch cabinet is too high, the PLC can be utilized to control the operation of the fan motor, thus to start the fan and facilitate air-discharge and cooling. The electric power temperature-control system realizes the functions of real-time monitoring and timely adjustment.
Description
Technical field
The utility model belongs to the temperature monitoring system of electric system, specifically relates to a kind of fiber grating electric power temperature controlling system.
Background technology
At present, have for the temperature monitoring means of switch cubicle a variety of, such as infrared monitoring temperature or Electronic Nose monitor temperature or the like, but these all exist certain hysteresis quality with can't implementation.Conventional infrared thermometer can't detect for the switch cubicle of sealing; And detection by electronic nose has certain hysteresis quality and inexactness, has huge potential safety hazard.
Summary of the invention
The purpose of the utility model provides a kind of real-time monitoring high-voltage switch gear in-cabinet temperature, and can make the electric power temperature control system of timely adjustment.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises the fiber-optical grating temperature sensor that is positioned at high-tension switch cabinet; Described fiber-optical grating temperature sensor is sent into the temperature signal of gathering in the GPZ through optical cable; GPZ connects fiber Bragg grating (FBG) demodulator through optical cable; Fiber Bragg grating (FBG) demodulator is sent into temperature signal in the PLC controller, and the PLC controller compares temperature signal that receives and setting value, outputs control signals to fan electromotor at last.
During described fiber Bragg grating (FBG) demodulator is uploaded onto the server the temperature signal of demodulation.
The utility model of employing technique scheme is gathered the temperature value in the high-tension switch cabinet through fiber-optical grating temperature sensor, and has the control and the execution function of lowering the temperature particularly.Because fiber grating is a kind of optical passive component, be through in grating, forming the phase grating of refractive index cycle property variation, so the fiber-optic grating sensor of development can accurately be gathered the temperature value at each position in the high-tension switch cabinet thus.When the high-voltage switch gear in-cabinet temperature is too high, can open fan through the operation of PLC control fan electromotor, be convenient to air draft and cooling.Thereby the function that the utility model has reached real-time monitoring, in time adjusted.
Description of drawings
Fig. 1 is the structure principle chart of the utility model.
Embodiment
As shown in Figure 1; The utility model comprises the fiber-optical grating temperature sensor 1 that is positioned at high-tension switch cabinet; Fiber-optical grating temperature sensor 1 is sent into the temperature signal of gathering in the GPZ 2 through optical cable 3, and GPZ 2 connects fiber Bragg grating (FBG) demodulator 4 through optical cable 3, and fiber Bragg grating (FBG) demodulator 4 is sent into the temperature signal after the demodulation in the PLC controller 5; In PLC controller 5, prestore relatively determining program of temperature; PLC controller 5 compares temperature signal that receives and setting value, outputs control signals to fan electromotor 6 at last, and fan electromotor 6 is controlled the rotation of fans 7 and stopped.Like this, when high-tension switch cabinet contact generation overheating fault, the utility model can accurately detect, and in time starts fan and lower the temperature, and has guaranteed the safe operation of high-tension switch cabinet.
In addition, during fiber Bragg grating (FBG) demodulator 4 can also be uploaded onto the server the temperature signal of demodulation, so that remote monitoring.
