ترویج تکنیک های ایمنی افزایش یک سیستم قدرتمند نیروگاه برق آبی تحت شرایط محیطی پر از قرار گرفتن در معرض بالا

Uninterruptible power systems in hydro plants under the surge environment of high exposure are susceptible to surge impact. In order to solve the problems of equipment malfunctions or failures caused by the surge, this paper applies the principle of surge energy transfer to design a low-voltage surge protection circuit, which prevents the surge from interfering with or damaging UPS devices. According to the IEEE and IEC standards test requirements, after the actual loads are connected to the load side of this circuit, surge generators are used to test the surge immunity of the surge protection circuit and actual load; test results confirm that the surge protection circuit proposed in this paper is effective for the protection of surge interference at low-voltage.
