1.结构及布局 MAP-Ⅱ机柜由三部分组成: (1)电源和空调部分这部份单独安装在一个机架中,有场地电源系统送来的交流50周及中频400周两种电源,再由这里经过继电控制送到MAP-Ⅱ的机架1和机架2。在这个机架的下部,安装有氟里昂致冷压缩机,通过直径20 mm的铜管线将高压氟里昂送到机架1和机架2。在机架1、2中由约10 mm的铜管线向组合块输送氟里昂,冷却发热的电子器件。致冷系统的控制、压力温度指示以及整机交直流手动供电开关、调节直流电压的调整设备、指示设备也一并安装在这个机架里或机架面板上。
1. Structure and layout MAP-Ⅱ cabinet consists of three parts: (1) power and air-conditioning part of this part of a separate installation in a rack, a venue power supply system and the frequency of 50 weeks AC 400 weeks two power supply, Here again through the relay control to MAP-Ⅱ rack 1 and rack 2. At the lower part of this rack, a Freon refrigeration compressor is installed and the high-pressure Freon is delivered to Rack 1 and Rack 2 via a 20 mm diameter copper pipe. In the racks 1 and 2, the freon is fed to the combination block by a copper line of about 10 mm to cool the heat-generating electronic components. Refrigeration system control, pressure and temperature instructions and the whole AC and DC manual power switch, adjust the DC voltage adjustment equipment, indicating equipment are also installed in this rack or rack panel.
