The Application Research Of Oil Chromatogram Monitoring Technique For Transformer Base On The Distributed Transducer

The operation reliability of the power transformer, the key apparatus in electrical power system, influences the safe operation of electrical power system directly. In order to keep the electrical power system safe, inspection and diagnosis of transformer insulation must be reinforced. The components and contents of gases dissolved in transformer oil can be used to reflect internal insulation faults of operating transformer. On the base of investigation the status in quo of the on-line monitoring technology of gases dissolved in transformer oil at home and abroad, and analysis of the elements that can affect the generally experimental results of dissolved gases and the diagnoses technology, this paper presents the principle and solution of on-line monitoring system with eigenvalue of gases dissolved in oil. The researches are shown mainly as follows:Thorough analysis transformer oil inside various solvations gas on-line monitors and fault diagnosis technique research present condition and meaning, the research electric power transformer insulates the structure characteristics, operational reliability evaluation, assessment and familiar fault, failure, fail in transformer interior and resolve in the oil the gas correspondence relate to, have to out in the transformer oil the component that resolve the gas circulate the internal insulation in transformer the fault, failure, fail the circumstance with valid body of energy of abundance now.Research the transformer oil color spectrum on-line that regards the transducer technique of the routine as the principle monitors technique principle; Resolve inside to the high polymers membrane permeation separation oil the basic principle of the gas proceeded the thorough analysis.The basic principle of detection gas dissolved in oil is analysised based the distribution sensors.The paper concrete application analysis six gases monitoring system in Yibin BaiSha substation. The system runs stably, and has the function of on-line monitoring and discovers the latent fault effectively and can become the warrant of condition service.
