Abstract

본 발명은 실험실등 저압 조건하에서 고압계통의 이상시 발생하는 아크를 수반하는 고장현상을 일으키는 실험용 고장 발생장치에 관한 것으로 전력설비의 고장현상을 파악하여 원인과 대책을 마련하기 위한 연구 및 교육용 설비이다.The present invention relates to an experimental failure generating device that causes a failure phenomenon involving an arc generated when an abnormality of a high pressure system occurs under low pressure conditions such as a laboratory. .

지금까지는 이러한 현상을 실제 규모인 고전압 하에서 수행해 왔으나 인력, 물자소모, 계통조건 및 실험에 대한 위험부담등으로 다양한 시험이 사실상 곤란하였으며 충분한 시험자료를 얻기 위한 많은 횟수의 시험시도가 어렵고 극히 제한적인 시험만을 수행할 수 밖에 없었다.Until now, this phenomenon has been carried out under high voltage, which is the actual scale, but various tests have been practically difficult due to manpower, material consumption, system conditions, and risks to experiments, and many tests are difficult and extremely limited to obtain sufficient test data. I couldn't help but do it.

따라서 저전압으로 구성된 모의 실험설비가 요구되며 이때 필연적으로 필요한 저전압 전극간에 자연고장 현상과 유사한 아크고장이 다양한 형태로 발생되어야 하는바 본 발명은 저압 시험회로에 아크고장을 임의로 인가시키므로서 고장에 수반된 제반전기 현상의 특성 및 분석에 유용한 연구시험 및 교육용 장치이다.Therefore, a simulation equipment consisting of low voltage is required, and at this time, an arc failure similar to a natural failure phenomenon must be generated between various low voltage electrodes, which is inevitably caused by a failure by arbitrarily applying an arc failure to a low voltage test circuit. It is a research test and educational device useful for the characterization and analysis of general electrical phenomena.
