成果名称:大功率低频测试电源的研制完成单位:高压供电公司成果简介:随着电网容量的不断增大,系统的短路容量也在增大,于是互感器厂家开发出了高饱和及带TPY 级电流互感器,由于 TPY 级互感器选用带气隙铁芯,其饱和磁通将很高,励磁电压也较高,给测试工作带来了较大的困难,需应用低频电源,采用低频法进行测试。而国内低频大功率电源几乎是空白,国外的设备也 Achievements Name: High-power low-frequency test power supply unit: high-voltage power supply company results Description: With the increasing capacity of the grid, the system short-circuit capacity is also increasing, so the transformer manufacturers have developed a high saturation and with TPY Current transformers, as the choice of TPY transformer with air gap core, the saturation flux will be high, the excitation voltage is high, to the test has brought greater difficulties, the need to apply low-frequency power, the use of low-frequency method test. The domestic low-frequency power supply is almost blank, foreign equipment also
