Abstract
The temperature measuring equipment of a kind of oil-filled transformer load tap changer oil chamber of the utility model, include temperature probe, temperature probe is connected with fiber Bragg grating (FBG) demodulator by optical cable, and fiber Bragg grating (FBG) demodulator connects warning module.Described temperature probe comprises fiber-optical grating temperature sensor and insulation crust, temperature probe access sub-connecting switch of transformer fuel tank.Described fiber-optical grating temperature sensor is GYT600 pottery monofocal fiber-optical grating temperature sensor.The utility model can implement thermometric accurately and rapidly to on-load tap changers of transformers grease chamber, good reliability, and directly can survey the timely faults of oil cabinet of tap switches internal temperature and send early warning.
Description
Technical field
The utility model relates to the thermometric of high-power transformer load tap changer oil chamber, belongs to automatic fields of measurement, especially relates to a kind of temperature measuring equipment of oil-filled transformer load tap changer oil chamber.
Background technology
Present oil-filled transformer temp measuring system does not include on-load shunting switch, and shunting switch is the key component of ULTC, and the good on-load tap changer of operation and maintenance is the basis ensureing safe operation of power system.Load ratio bridging switch can not only steady load center voltage, and is contact network, adjustment load trend and improves without indispensable visual plants such as the distribution of work, and therefore, ULTC occupies definitely large ratio in the electrical network of China.But in the last few years, load ratio bridging switch was in operation abnormal conditions constantly, and tripping fault is also have generation.Shunting switch has independent grease chamber, usually shows as the abnormal rising of oil temperature, so the temperature measuring equipment being provided with on-load shunting switch is necessary before load ratio bridging switch fault.
Utility model content
The technical problems to be solved in the utility model is the temperature measuring equipment providing a kind of oil-filled transformer load tap changer oil chamber.
The utility model solves the technical scheme that its technical matters adopts:
A temperature measuring equipment for oil-filled transformer load tap changer oil chamber, includes temperature probe, and temperature probe is connected with fiber Bragg grating (FBG) demodulator by optical cable, and fiber Bragg grating (FBG) demodulator connects warning module.
Described temperature probe comprises fiber-optical grating temperature sensor and insulation crust, temperature probe access sub-connecting switch of transformer fuel tank.
Described fiber-optical grating temperature sensor is GYT600 pottery monofocal fiber-optical grating temperature sensor.
Described insulation crust is ceramic pipe.
The beneficial effect that the utility model has is:
The utility model structure is simple, production cost is low, can implement thermometric accurately and rapidly, good reliability to on-load tap changers of transformers grease chamber, and directly can survey the timely faults of oil cabinet of tap switches internal temperature and send early warning.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. sub-connecting switch of transformer fuel tank, 2. fiber-optical grating temperature sensor, 3. temperature probe, 4. insulation crust, 5. optical cable, 6. fiber Bragg grating (FBG) demodulator, 7. warning module.
Embodiment
As shown in Figure 1, the temperature measuring equipment of a kind of oil-filled transformer load tap changer oil chamber of the utility model, includes temperature probe 3, and temperature probe 3 is connected with fiber Bragg grating (FBG) demodulator 6 by optical cable 5, and fiber Bragg grating (FBG) demodulator connects warning module 7.
Described temperature probe 3 comprises fiber-optical grating temperature sensor 2 and insulation crust 4, and fiber-optical grating temperature sensor 2 is placed in insulation crust 4, and temperature probe 3 accesses sub-connecting switch of transformer fuel tank.By the fiber-optical grating temperature sensor in temperature probe, temperature is measured, information transmission be optical cable, the output terminal of warning module connecting fiber grating demodulation instrument, just sends early warning signal when temperature exceeds standard value.
Described fiber-optical grating temperature sensor is GYT600 pottery monofocal fiber-optical grating temperature sensor.
Described insulation crust is ceramic pipe.
Principle of work of the present utility model is as follows:
Temperature probe 3 accesses in sub-connecting switch of transformer fuel tank 1, thermometric is carried out by the fiber-optical grating temperature sensor 2 in temperature probe 3, the transfer function of signal is realized by optical cable 5, the signal receiving that optical cable 5 transmits by fiber Bragg grating (FBG) demodulator 6, reflect the temperature of oil cabinet of tap switches, the temperature signal that warning module 7 exports according to fiber Bragg grating (FBG) demodulator 6 compares with default warning value, and when temperature exceedes warning value, warning module 7 sends early warning signal.
