摘　　要：介绍了安徽万瑞冷电科技有限公司研制的首条冷绝缘(CD)型10m/35kV/2kA高温超导电缆过冷液氮低温系统。系统主要由泵箱、冷箱、输液管道、液氮储槽及监控系统组成。该系统由G-M制冷机提供冷量,低温液氮泵提供循环动力,过冷液氮为闭循环介质。给出了过冷液氮低温系统调试运行结果。The first subcooled LN2 system with cool insulation CD -type and 10m/35kV/25kA for HTS cables was developed by Vacree. The system was mainly composed of pump box, cold box, transfusion pipe, liquid nitrogen storage tank and monitoring system. The cooling capacity for the system was from G - M cryocooler, the system was driven by LN2 pump and subcooled LN2 was used as refrigerants. The test results for the cryogenic system were given.
