摘要
介绍了我国新研制成的首条双通道热绝缘型 4 M- 2 0 0 0 A高温超导电缆制冷系统。该系统由 G- M制冷机提供制冷量 ,过冷液氮为冷却介质 ,通过液氮泵循环 ,组成一个闭式循环制冷系统。给出了制冷系统的调试结果。系统上装有温度、压力、流量、液位等测量仪表 ,并备有一个减压抽空系统 。
The new development of the cryogenic LN 2 system for the first 4M-2000A two passages superconductor cable with hot insulates in China is described in this paper. The refrigeration of system is provided by AL300 G-M refrigerator, and circulated by the BNCP-30-000 liquid nitrogen pump. There are measuring with temperature, pressure, flow, level of liquid nitrogen etc. and have a decompression system for the affixation refrigeration. The successful results of tests and experiments of the cryogenic LN 2 system etc. are introduced.
