电力机车在运行中按有关技术规定,允许接触网电压在19～29kV间波动。如果超出此范围,特别是低于19kV时,电力机车上的劈相机及其他辅助电动机将会因电压过低而烧损。我段韶山1型323号电力机车于1984年8月24日在阳安线通过欧家坡车站时,因网压下降至12.6kV造成两台劈相机烧损的事故。据乘务人员反映及实测,电力机车上零压
Electric locomotive in operation according to the relevant technical regulations, allowing contact voltage fluctuations between 19 ~ 29kV. If this range is exceeded, especially when it is below 19kV, split-phase cameras and other auxiliary motors on electric locomotives will burn out due to low voltage. I section Shaoshan Type 323 electric locomotive on August 24, 1984 in the Yang An line through the European slope station, due to the network pressure dropped to 12.6kV two split-camera burning accident. According to the crew reflect and measured, zero pressure on the electric locomotive
