船舶电站是船舶的重要组成部分,各国验船部门对电站的校验入级都有明确的规定。但目前我国生产的船用交流发电机额定电压仍为400伏,这与我国及国际上在这方面的验收规定相矛盾。我国船用交流发电机额定电压是在解放初期参照苏联船规和一机部陆用发电机定下来的。当时在一机部陆用发电机中,有一个额定电压等级是400伏。这种发电机主要用于小型发电站。因发电站输送电力线路长,线路电压降比较大,所以定为400伏。船用发电机也套用了这个额定电压等级。这不仅对我国建造的船舶进入国际市场不利,也对380伏为额定电压的用电设备以及以220伏为额定电压的照明设备的使用不利。一、各国规范虽有许多不同点,但对
Ship power station is an important part of the ship, the ship inspection departments of all countries have clear provisions on the level of the power station. However, at present, the rated voltage of marine alternators produced in China is still at 400 volts, which conflicts with our country’s and international acceptance requirements in this regard. China marine AC generator rated voltage in the early liberation of the reference to the Soviet ship regulation and a machine set land generator set down. At that time in a plane with land generators, there is a rated voltage level is 400 volts. This generator is mainly used for small power stations. Due to the power plant transmission line length, line voltage drop is relatively large, so set to 400 volts. Marine generators also apply this rating. This is not only unfavorable to the entry into the international market of our country’s ships, but also to the use of 380 volt rated voltage electrical equipment and 220 volt rated voltage lighting equipment. First, although there are many differences between the norms, but right
