当前,许多变压器在线监测系统的故障诊断率低,且自身的稳定性不好,致使其发挥的作用有限。由于光纤气体传感器基于光通信传播技术,其具有抗干扰性强、损耗低、本质安全、易于组网和智能化监测等显著特点。在光纤技术的基础上;设计了新型变压器油质在线监测分析系统。该系统用于监测变压器发生故障时油中产生的CH4,C2H4、C2H2和CO 4种气体的浓度,从而判断故障状况,提高系统的可靠性。 At present, many transformer online monitoring system fault diagnosis rate is low, and its stability is not good, resulting in its limited role. Fiber optic gas sensor based on optical communication technology, which has strong anti-interference, low loss, intrinsically safe, easy networking and intelligent monitoring and other notable features. On the basis of optical fiber technology, the design of a new transformer oil quality online monitoring and analysis system. The system is used to monitor the concentrations of CH4, C2H4, C2H2 and CO4 gases produced by the oil in the event of a transformer failure to determine the fault condition and improve the system reliability.
