The invention discloses a detection platform for a spectral type optical fiber sensor. The detection platform for the spectral type optical fiber sensor comprises a transformer oil tank, an oil-gas separator, a gas optical fiber detection device, a first oil passing pipe, a first oil discharge valve, a second oil passing pipe and a second oil discharge valve; transformer oil is filtered with the oil-gas separator to filter gas dissolved in oil, then the gas enters into a sensor chamber, a wavelength of incident laser light is regulated by a laser light source to enable an output spectrum of the incident laser light to be anastomosed to an absorption spectral line of the gas to be detected, detection of the concentration of the gas to be detected is realized by measuring a ratio of an incident light intensity and an emergent light intensity, then a processed data result is transferred to a monitor terminal, and an on-station worker can directly see the fault and the ageing state of a transformer. The detection platform for the spectral type optical fiber sensor can achieve the purpose of online detection without stopping transformer equipment, can accurately detect the content of characteristic gas produced by the fault and ageing of the transformer and thus diagnoses the fault type and the ageing degree of the transformer.
Description
technical field [0001] The application relates to the field of on-line insulation monitoring and fault diagnosis of electrical equipment, in particular to a detection platform for spectral optical fiber sensors. Background technique [0002] The safe and reliable operation of electrical equipment is the first line of defense to avoid major accidents in the power system. However, real-time online diagnosis of electrical equipment faults and aging status is one of the keys to ensure the safe production of the power system and realize efficient maintenance of equipment. During the operation of electrical equipment, electrical equipment will produce various characteristic quantities that reflect the operating state, such as characteristic gases that reflect failure and aging (oil-immersed equipment H2, CH4, C2H2, C2H4, C2H6, CO, CO2, etc.). [0003] Spectral optical fiber sensors are mainly divided into refractive index change type, absorption type and Raman type. Compared with...
