摘要

摘要: 空间环境地面模拟装置是哈尔滨工业大学承建的国家重大科技基础设施项目，其包含的空间等离子体环境模拟与研究系统是用于提供磁重联过程等基本物理过程的时空演化规律研究的平台。在研究地球磁尾三维磁重联时，使用处于真空环境内的偶极磁场线圈和两个磁镜场线圈来提供研究所需的模拟背景磁场，其中偶极场线圈为一个总电感为17.4 mH、总电阻为30.25 mΩ的单个线圈，而磁镜场线圈为两个线圈镜像对称设置并串联连接，总电感30.16 mH，总电阻58.81 mΩ。为了产生实验所需背景磁场的幅值和持续时间，研制并测试了两套总能量3.36 MJ的脉冲电源，在进行地球磁尾三维磁重联实验时两套电源需要同时工作。用于驱动偶极场线圈的脉冲电源按照实验需求可以在充电压不大于20 kV的情况下，能够提供超过9 kA的峰值电流，95%峰值电流的持续时间超过了5 ms，由峰值时刻降低到10%峰值时刻的时间不超过130 ms；用于驱动磁镜场线圈的脉冲电源按照实验需求可以在充电压不大于20 kV的情况下，能够提供超过8 kA峰的值电流，95%峰值电流的持续时间超过了5 ms，由峰值时刻降低到10%峰值时刻的时间不超过130 ms。

Abstract: A new large research infrastructure for fundamental researches on the space environment, Space Environment Simulation Research Infrastructure (SESRI), is being constructed. When studying the three-dimensional magnetic reconnection of the earth’s magnetotail, the dipole coil and two magnetic mirror coils in vacuum environment are used to provide the simulated background magnetic field required for the study. To generate the amplitude and duration of the background magnetic field required by the experiment, two sets of pulsed power supplies with a total energy of 3.36 MJ are developed and tested. The pulsed power supply used to drive the dipole coil can provide a peak current of more than 9 kA when the charging voltage is not more than 20 kV, and the duration of 95% peak current is more than 5 ms, the time from peak time to 10% peak time does not exceed 130 ms; According to the experimental requirements, the pulsed power supply used to drive the magnetic mirror coil can provide a peak current of more than 8 kA when the charging voltage is not more than 20 kV, the duration of 95% peak current is more than 5 ms, and the time from peak time to 10% peak time does not exceed 130 ms. The two sets of pulsed power supplies need to work simultaneously in the three-dimensional magnetic reconnection experiment of the earth’s magnetotail.
