摘　　要：储能系统变流器低压侧通常采用单相多根电缆并联使用,敷设于集装箱夹层内,由于敷设空间较小,且电缆数量较多,电缆可能出现温升较高的问题。以某工程的典型储能单元为例,在储能单元交流侧电流不变的条件下,计算电缆敷设方式对温升的影响,并开展试验验证。结果表明,在电缆选型满足载流量要求时,电缆通过换位敷设,可使电缆周围磁场均匀分布,减小各相电缆的阻抗差异,抑制电缆夹层中产生的涡流损耗。各电缆之间间隔适当的距离,电缆表面的自然对流散热量将显著提高,可有效降低电缆温升。Many cables per phase were used for low voltage side of energy storage converter,and they were laid in a small layer of container.Many cables laying in a small space,thus the temperature may be very high.Taking a typical energy storage unit of a project as an example,under the condition that current on AC side of energy storage unit remain unchanged,the impact of cable laying mode on the temperature was studied and tested.The results showed that,for a reasonable current carrying capacity,swapping order could provide an even magnetic field and decrease the difference of impedance,and suppress the eddy current loss of container layer.Set a proper space between cables would increase the natural convection heat dissipation and control the temperature.
