| 摘 要： | 熔断器、单极开关等产品的短路试验需要单相电源。在利用三相试验变压器供电时，为满足不同试验电压的要求，除了三相试验变压器常用的调压方式外，还可通过变压器不同输入、输出连接方式及低压绕组的多种三相不对称接法进行调压，得到更多的单相电压等级。

| Abstract: | Single phase power supply are needed for the short circuit test of fuses, single pole switches etc.. While applying the power supply of three phase testing transformer, in order to satisfy the requirements for various test voltages , besides the usual voltage regulating modes of three phase testing transformer which have been used, it can also be regulated by different connecting modes for input and output of the transformer, and many asymmetrical three phase connections for low voltage windings, so that more single phase voltage classes are obtained. |
