一种油浸式变压器故障时能自保持运行的方法研究

A Method Study of Oil-immersed Transformer Can Self-maintained Running When Faults Occurred

针对油浸式变压器由于故障产生的泄压和爆燃现象,提出一种变压器发生故障时能自保持运行的逻辑;并根据该逻辑设计一种油路设备的方案。上述逻辑和方案共同构建了一种油浸式变压器故障时能自保持运行的方法。该方法的应用能够缩减由于变压器故障导致的停电时间,达到及时恢复供电的目的。同时减轻了变压器产生泄压或者爆燃事故时,对周围人身、财产安全和环境的影响。为智能变压器的设计者提供了一个新思路。

Aiming at the phenomenon of pressure relief and deflagration caused by the faults of oil-immersed transformer,a logic was proposed that the transformer can keep self-maintained running when faults occurred,and according to the logic,a scheme of oil circuit equipment was designed. The above logic and the scheme together constructed a method of self-maintaining operation of oil-immersed transformer. The application of the method could reduce the power outage time caused by transformer failure to achieve the purpose of timely restoration of power supply. At the same time,it alleviated the influence on the surrounding personal and property safety and environment when the transformer produces pressure relief or deignition accident. The method provides a new idea for the designers of intelligent transformer.
