- 摘要:
- 日前,国内普遍将磁放大器式和晶闸管式恒电位仪用于大型储罐以及长距离输油管道的外加电流阴极保护。随着大功率电子开关器件的出现,已成功开发一种新型逆变式恒电位仪,在2万m~3储罐阴极保护的实际应用表明,不仅其性能稳定可靠,而且节能效果显著,是一种理想的更新换代产品。
Magnetic amplifier and transistor constant electric potential instrument are usually applied in additional current cothode protection of large storage tank and long distance pipeline.With the invention of large power electronic switch unit,a new conversion constant potential unit has been researched and developed.In application of 20000 m3 storage tank engineering,it results in its stable property and obvious efficiency,and this new instrument is ideal substituted product.1999,3(3): 45-47 收稿日期:1999-1-14参考文献:
