一、设备 1.电源变压器阻焊机的负载持续率较低,在一个单位周期的短时间内承受大电流,因此在选择电源变压器时要考虑两点:(1)从发热方面考虑要具有足够的容量;(2)通电时电压降不能太大。
First, the equipment 1. Power transformer Solder welder’s lower load sustained in a short period of time to withstand high current, so when choosing a power transformer to consider two points: (1) Consideration from the heat to have enough Capacity; (2) when the voltage drop can not be too large.
