Description

Technical Field

[0001] The present invention relates to the field of sensor detection technology, and more specifically, to a MEMS optical fiber sensing temperature controller. Background Art

[0002] It is very important to control the temperature of oil-immersed transformers because temperature control directly affects the performance, life and safety of the transformer. The main reason is that the insulation system of oil-immersed transformers usually uses insulating oil (insulating medium) to maintain electrical isolation between electrical components. High temperature causes the insulating oil to decompose and age, impairing the insulation performance, thereby increasing the risk of insulation breakdown. By controlling the temperature, the life of the insulation system can be extended. And too high temperature will limit the load capacity of the transformer, so by controlling the temperature, it can be ensured that the transformer operates under rated load conditions. At the same time, the increase in temperature will cause thermal stress to the internal components of the transformer (such as windings and core iron), which may cause deformation, expansion and damage of the components. Harsh temperature conditions may cause mechanical failures. And by controlling the temperature of oil-immersed transformers can help reduce energy waste, and abnormal temperature increases may be an indication of internal faults or failures of the transformer. By timely detecting and controlling the temperature, serious faults and accidents can be prevented and the safe operation of the equipment can be ensured.

[0004] When this structure is in use, a high-spectral-fineness optical interference-sensitive microcavity is made inside the MEMS fiber FP temperature-sensitive chip, which can convert the displacement of the single-crystal silicon diaphragm under the action of temperature into a change in the wavelength of the interference light. It has high resolution, high voltage resistance and a large linear dynamic range, which is conducive to achieving ultra-high-precision measurement. However, when conducting temperature acquisition tests, this structure is not easy for the transformer oil to fully contact the sensor, resulting in inaccurate stable detection.

[0025] As attached Figure 1-7 A MEMS optical fiber sensing temperature controller shown in the figure has a flow guide detection component arranged on a reinforced housing 1. After the high-temperature oil is gathered in the reinforced housing 1 and wraps the second capillary temperature sensing detection tube 8 and the temperature transfer plate 5, it is gathered through the flow guide cone shell 12 and then discharged through the discharge frame opening 13, so that the oil can easily pass through the sensing temperature controller when flowing in the transformer, thereby ensuring the detection accuracy. The first capillary temperature sensing detection tube 7 transfers the temperature to the temperature transfer plate 5 for temperature detection through the detection head 4. At the same time, the second capillary temperature sensing detection tube 8 is arranged to increase the contact area with the high-temperature oil of the transformer, thereby avoiding inaccurate detection caused by excessively fast oil flow rate. When the oil flows in the reinforced housing 1, it is diverted through the dislocation frame opening 10, and at the same time, the temperature is transferred through each temperature transfer plate 5 and the second capillary temperature sensing detection tube 8, thereby realizing the function of detecting the temperature in different directions outside the device. In addition, each detection structure is compared with each other to ensure the detection accuracy. The specific structure of the component is arranged as follows;

[0026] The flow guide detection assembly includes a protective liner tube 2 disposed in a reinforced shell 1, a temperature detector body 3 is disposed inside the protective liner tube 2, the protective liner tube 2 is configured to be hollow, and the temperature detector body 3 is installed inside the protective liner tube 2 through a tight hoop;

[0027] A plurality of detection heads 4 for temperature detection are distributed on the outside of the temperature detector body 3. A plurality of through holes 11 are formed through the surface of the protective inner liner tube 2, and each through hole 11 is located in a corresponding through hole 11. The detection heads 4 pass through the through holes 11 and extend to the outside of the protective inner liner tube 2.

[0028] A plurality of temperature transfer plates 5 are distributed on the outside of the protective liner tube 2, and each temperature transfer plate 5 is located at one end of a corresponding detection head 4;

[0029] The outer side of the protective lining tube 2 is sleeved with a guide plate 9, which is located on the top of the detection head 4. A number of offset frame openings 10 are opened on the guide plate 9. A positioning buckle 6 is fixedly set on one side of the multiple temperature transfer plates 5, and each positioning buckle 6 is opened with a positioning arc groove 17. The vertical cross-section shape of the positioning arc groove 17 is arc-shaped. The first capillary temperature sensing detection tube 7 is clamped in the positioning arc groove 17. The second capillary temperature sensing detection tube 8 is set at both ends of the first capillary temperature sensing detection tube 7.

The second capillary temperature sensing detection tube 8 is located in the offset frame opening 10, and the second capillary temperature sensing detection tube 8 is sleeved on the guide plate 9.

[0030] A guide cone shell 12 is fixedly provided at one end of the reinforced shell 1. The vertical cross-section of the guide cone shell 12 is conical, and one end of the protective liner tube 2 extends to one side of the inner wall of the guide cone shell 12. A plurality of discharge frame openings 13 are penetrated through the outer side of the guide cone shell 12. A baffle 14 is provided at one end of the reinforced shell 1 away from the guide cone shell 12. The baffle 14 is installed on the reinforced shell 1 by bolts. The baffle 14 is sleeved on the outer side of the protective liner tube 2. A plurality of liquid inlet holes 15 are penetrated through the baffle 14. A signal transmission wire 16 is installed at one end of the temperature detector body 3 through an electrode. The signal transmission wire 16 is located in the protective liner tube 2.

[0032] When the high-temperature oil of the transformer contacts the second capillary temperature-sensitive detection tube 8, the second capillary temperature-sensitive detection tube 8 is heated and conducts heat to the first capillary temperature-sensitive detection tube 7. The first capillary temperature-sensitive detection tube 7 transmits the temperature to the temperature transfer plate 5 for temperature detection via the detection head 4. Meanwhile, the second capillary temperature-sensitive detection tube 8 increases the contact area with the high-temperature oil of the transformer, thereby avoiding inaccurate detection caused by excessively fast oil flow.

[0033] When the oil of the transformer flows in the reinforced shell 1, it is diverted through the offset frame 10, and at the same time, the temperature is conducted through each temperature transfer plate 5 and the second capillary temperature sensing detection tube 8, thereby realizing the function of detecting the temperature in different directions outside the device. At the same time, each detection structure is compared with each other to ensure the detection accuracy.

[0034] Different from the prior art, the present application discloses a MEMS optical fiber sensing temperature controller, in which high-temperature oil is gathered in a reinforced shell 1 and wrapped around a second capillary temperature sensing detection tube 8 and a temperature transfer plate 5, and then gathered through a guide cone shell 12 and discharged through a discharge frame opening 13, so that the oil can easily pass through the sensing temperature controller when flowing in the transformer, thereby ensuring detection accuracy. The first capillary temperature sensing detection tube 7 transfers the temperature to the temperature transfer plate 5 for temperature detection through a detection head 4, and at the same time, the second capillary temperature sensing detection tube 8 is provided to increase the contact area with the high-temperature oil of the transformer, thereby avoiding inaccurate detection caused by excessively fast oil flow rate, and when the oil flows in the reinforced shell 1, it is diverted through the offset frame opening 10, and at the same time, the temperature is transferred through each temperature transfer plate 5 and the second capillary temperature sensing detection tube 8, thereby realizing the function of detecting the temperature in different directions outside the device, and also comparing each detection structure with each other to ensure detection accuracy.
